[0003] Traditional filter cores have many drawbacks in structural design. In terms of filtration efficiency, many filter cores use a relatively conventional filtration structure, and the filtration area is limited, making it difficult to efficiently remove impurity particles in oil, resulting in difficulty in meeting the use requirements of some high-precision equipment for filtered oil. In terms of installation and maintenance, the connection method of some filter cores is simple and rough, such as using a buckle type connection. This connection method is prone to loosening during equipment operation due to factors such as vibration. Once loosened, it not only affects the filtration effect, but also may cause oil leakage, posing a safety hazard to production. Moreover, the components of traditional filter cores are mostly fixed combinations, which are difficult to adjust flexibly according to the actual needs of different customers.

Detailed Implementation

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] like Figs. 1 to 3 As shown, a corrugated disc filter element includes a disc filter element 10 assembled from multiple corrugated filter element assemblies 20. A top adapter 40 is connected to the top of the disc filter element 10, and a bottom adapter 30 is connected to the bottom of the disc filter element 10. The corrugated filter element assembly 20 includes a series connecting tube 201. Two symmetrically distributed slots 204 are formed on the outer side of the series connecting tube 201. Sealing rings 205 are fitted into the slots 204. A corrugated filter chip 206, fitted onto the outer side of the series connecting tube 201, is disposed between the two sets of sealing rings 205. The corrugated filter chip 206 is movably inserted into the series connecting tube 201. There is a support plate 207, one end of which is inserted into the series connecting pipe 201. A connecting block 202 is connected inside the series connecting pipe 201. The connecting block 202 is connected to the support plate 207 through the first fixing wire 203. The sealing ring 205 is connected to the support plate 207 through the second fixing wire 208. The top of the series connecting pipe 201 of the top corrugated filter element assembly 20 of the disc filter element 10 is detachably connected to the top adapter 40. The bottom of the series connecting pipe 201 of the bottom corrugated filter element assembly 20 of the disc filter element 10 is detachably connected to the bottom adapter 30.

[0030] Working principle:

[0031] Assembly process: First, the connecting block 202 and the series connecting pipe 201 are integrally injection molded. Then, a sealing ring 205 is fitted onto the slot 204 of the series connecting pipe 201. Next, the corrugated filter chip 206 is fitted onto the series connecting pipe 201 between the two sets of sealing rings 205, and the support piece 207 is movably inserted into the corrugated filter chip 206, with one end connected to the series connecting pipe 201. The connecting block 202 and the support piece 207 are connected by the first fixing screw 203, and the sealing ring 205 is connected to the support piece 207 by the second fixing screw 208, thus completing the assembly of one corrugated filter element assembly 20. Multiple corrugated filter element assemblies 20 are assembled in the same way, and they are sequentially spliced ​​into a disc filter element 10 through the threaded structure of the series connecting pipe 201. Finally, connect the top of the series connection tube 201 of the topmost corrugated filter element assembly 20 of the disc filter element 10 to the top adapter 40, and connect the bottom of the series connection tube 201 of the bottommost corrugated filter element assembly 20 of the disc filter element 10 to the bottom adapter 30.

[0032] Usage: When filtering oil, connect to external equipment via bottom adapter 30 and top adapter 40. After the filtered oil enters the disc filter element 10, it is filtered by the corrugated filter chip 206 and then discharged. The corrugated filter chip 206 plays the main filtering role, and its corrugated structure greatly increases the filtration area.

[0033] During the operation of the corrugated filter sheet 206, the support sheet 207 plays an important supporting role. It is movably inserted on the corrugated filter sheet 206, one end is inserted with the series connection pipe 201, and is connected with the connection block 202 through the first fixing wire 203, which ensures the shape stability of the corrugated filter sheet during the filtering process, prevents it from deforming due to oil pressure and other factors, and thus ensures the stability of the filtering effect.

[0034] At the same time, the sealing rubber ring 205 also plays an indispensable role. The sealing rubber ring 205 is sleeved on the clamping groove 204 outside the series connection pipe 201, and is connected with the support sheet 207 through the second fixing wire 208. It can effectively prevent oil leakage between the filter core assemblies, so that the oil can only pass through the corrugated filter sheet according to the designed path, ensuring the completeness and efficiency of the filtering.

[0035] In addition, the number of sheets of the filter core can be increased or decreased according to customer needs. When higher filtering precision is required, the number of corrugated filter sheets 206 can be increased to allow the oil to pass through more levels of filtering; when larger flow of oil needs to be processed, the number of sheets can be appropriately reduced to ensure that the oil can smoothly pass through the filter core, meeting different use requirements

[0036] Maintenance process: when the filter core needs to be cleaned or replaced, only the top adapter 40 and the bottom adapter 30 need to be disassembled from the disc filter core 10, and then each corrugated filter assembly 20 is disassembled in turn, so that each part can be cleaned or replaced. After cleaning or replacement is completed, reassemble in the reverse order of the assembly process.

[0037] Example 2

[0038] As Figs. 1 to 3As shown, a corrugated disc filter element includes a disc filter element 10 spliced by a plurality of corrugated filter element assemblies 20, a top adapter 40 connected to the top of the disc filter element 10, and a bottom adapter 30 connected to the bottom of the disc filter element 10. The corrugated filter element assembly 20 includes a series connection pipe 201, two sets of symmetrically distributed clamping grooves 204 formed on the outer side of the series connection pipe 201, a sealing rubber ring 205 sleeved on the clamping grooves 204, a corrugated filter sheet 206 sleeved on the outer side of the series connection pipe 201 between the two sets of sealing rubber rings 205, a support sheet 207 movably sleeved on the corrugated filter sheet 206, one end of the support sheet 207 being sleeved on the series connection pipe 201, a connecting block 202 connected in the series connection pipe 201, the connecting block 202 being connected to the support sheet 207 through a first fixing wire 203, the sealing rubber ring 205 being connected to the support sheet 207 through a second fixing wire 208, the top of the series connection pipe 201 of the corrugated filter element assembly 20 at the top of the disc filter element 10 being detachably connected to the top adapter 40, and the bottom of the series connection pipe 201 of the corrugated filter element assembly 20 at the bottom of the disc filter element 10 being detachably connected to the bottom adapter 30.

[0039] The series connection pipe 201 and the connecting block 202 are both plastic products.

[0040] The above arrangement has the following advantages:

[0041] Cost advantage

[0042] Plastic materials are relatively cheaper than many other materials such as metals. In mass production, using plastic to make the series connection pipe 201 and the connecting block 202 can effectively reduce production costs. This makes the filter element more price competitive in the market and can provide users with a product with higher cost performance.

[0043] For example, compared with metal materials such as stainless steel, the raw material price of plastic may be only a fraction of that of metal, and the processing technology is simple and the processing cost is relatively low, which helps enterprises to reduce the overall production investment while ensuring product quality.

[0044] Good chemical stability

[0045] In an oil filtering environment, plastic products can resist chemical corrosion of oil. Most plastics have good resistance to oil substances and will not be corroded by chemical reaction with oil as some metal materials are.

[0046] For example, polycarbonate and other plastic materials can maintain chemical stability in various oil environments, ensuring the structural integrity of the series connection pipe 201 and the connecting block 202, thereby prolonging the service life of the filter element.

[0047] Light weight

[0048] The density of plastic is relatively small, which makes the series connection pipe 201 and the connection block 202 relatively light in weight. This is very advantageous for the installation and movement of the entire filter element.

[0049] When 3-4 such filter elements need to be installed in a filter, the relatively light weight facilitates the operation of the operator and reduces the physical exertion during the installation process. Moreover, when the filter element needs to be moved or replaced, it is also easier to carry, and the operator will not be inconvenienced by the excessive weight.

[0050] Easy to process and form

[0051] Plastic can be made into complex shapes through various processing methods such as injection molding. The series connection pipe 201 and the connection block 202 are integrally injection molded, which ensures the tightness of the connection between the two and the integrity of the structure.

[0052] For example, injection molding can accurately manufacture complex structures such as the clamping slot 204 on the series connection pipe 201 and the part connecting the support sheet 207 on the connection block 202, and can achieve large-scale and high-efficiency production, improving production efficiency.

[0053] Good insulation

[0054] In some special filtration scenarios, there may be problems such as static electricity. Plastic products have good insulation performance, which can avoid potential risks caused by static electricity, such as the influence of impurities in oil on the filtration effect due to static adsorption, etc.

[0055] The series connection pipe 201 and the connection block 202 are integrally injection molded.

[0056] The advantages of the above arrangement are:

[0057] High structural integrity

[0058] Integrally injection molded makes the series connection pipe 201 and the connection block 202 form a whole structure. Compared with other connection methods such as welding, gluing, etc., there is no connection interface, which avoids the structural damage caused by the loosening and breaking of the connection part.

[0059] For example, during the filtration process, the pressure and flow of oil may impact the internal structure of the filter element. The integrally injection molded structure can better withstand such pressure, ensuring the stable connection between the series connection pipe 201 and the connection block 202, and maintaining the normal working state of the filter element.

[0060] Enhanced sealing

[0061] The integrally injection-molded series connection pipe 201 and the connection block 202 can effectively prevent oil leakage due to the absence of a connection gap. In the process of filtering oil, sealing performance is crucial, and any slight leakage can affect the filtering effect.

[0062] For example, compared with threaded connection or other detachable connection methods, the integrally injection-molded structure does not have the risk of leakage caused by factors such as aging of sealing gaskets and loose connection, thereby ensuring that the oil flows inside the filter element according to the predetermined path and improving the accuracy and reliability of the filtering.

[0063] High production efficiency

[0064] The integrally injection-molded process can achieve large-scale and high-efficiency production under reasonable mold design. The series connection pipe 201 and the connection block 202 are injection molded together, reducing the production steps and shortening the production cycle.

[0065] For example, on an automated injection molding production line, only plastic raw materials need to be injected into the mold, and the series connection pipe 201 with the connection block 202 can be obtained by one-time molding. Compared with the method of manufacturing separately and then connecting, the production efficiency is greatly improved, and the production cost is reduced.

[0066] High dimensional accuracy

[0067] Injection molding can accurately control the size and shape of the series connection pipe 201 and the connection block 202. In a filter element structure with strict design requirements, this high-precision size control can ensure the fitting accuracy between various components.

[0068] For example, the position and size accuracy of the clamping slot 204 on the series connection pipe 201 can be guaranteed, facilitating the installation of the sealing rubber ring 205 and ensuring that the sealing rubber ring 205 tightly fits the clamping slot 204, further improving the overall performance of the filter element.

[0069] The top of the series connection pipe 201 is provided with internal threads, and the bottom of the series connection pipe 201 is connected with external thread bosses. A group of external thread bosses of the series connection pipe 201 is inserted into the internal threads of another group of series connection pipes 201.

[0070] The advantages of the above arrangement are:

[0071] High connection stability

[0072] The threaded connection method can provide reliable connection force. During the operation of the filter element, especially during the filtering of oil, it will be affected by factors such as oil pressure and equipment vibration. Through the tight fit of the external thread bosses and the internal threads, a group of series connection pipes 201 is firmly connected with another group, avoiding loosening or separation between the filter element assemblies during use.

[0073] For example, in an industrial environment, the filter may be subjected to continuous vibration due to the operation of the machine. The threaded connection can effectively resist vibration, ensuring the structural integrity of the disc filter element 10 and ensuring the stable progress of the filtration process.

[0074] Convenient assembly and disassembly

[0075] Threaded connection is a relatively simple and easy-to-operate connection method. When assembling multiple corrugated filter element assemblies 20, the operator can easily screw the outer threaded protrusion of one series connection pipe 201 into the inner thread of another series connection pipe 201 to complete the splicing. Similarly, when maintenance, cleaning or replacement of parts of the filter element is required, the assembly can also be easily disassembled.

[0076] For example, compared with some connection methods that require special tools or complex operation steps, threaded connection only requires the use of simple tools, and even in some cases, manual assembly and disassembly can be completed, greatly improving work efficiency.

[0077] Good connection tightness and good sealing

[0078] When the outer threaded protrusion and the inner thread are correctly screwed together, they can form a tight fit between them, effectively preventing oil leakage between the series connection pipes 201. This tight connection can ensure that the oil flows inside the filter element according to the predetermined path, i.e. from the top adapter 40, through the corrugated filter sheet 206, and then from the bottom adapter 30.

[0079] For example, when filtering oil with high precision requirements, good sealing can prevent unfiltered oil from mixing with filtered oil, ensuring the quality of the filtered oil.

[0080] Flexible adjustment of the number of filter element assemblies

[0081] Due to the use of threaded connection, the number of corrugated filter element assemblies 20 can be easily increased or decreased according to the specific needs of the customer. Users can flexibly assemble the appropriate number of corrugated filter element assemblies 20 to form the disc filter element 10 according to the required filtration precision, flow rate and other factors.

[0082] For example, when the flow rate of the oil to be treated is large and the filtration precision requirement is not particularly high, the number of corrugated filter element assemblies 20 can be appropriately reduced to reduce the resistance of the oil passing through the filter element, ensuring smooth passage of the oil; conversely, when higher filtration precision is required, the number of assemblies can be increased to achieve multi-stage filtration.

[0083] The top of the series connection pipe 201 of the corrugated filter element assembly 20 at the top of the disc filter element 10 is screwed with the top adapter 40, and the bottom of the series connection pipe 201 of the corrugated filter element assembly 20 at the bottom of the disc filter element 10 is screwed with the bottom adapter 30.

[0084] The advantages of the above arrangement are:

[0085] Connection stability and sealing

[0086] Leakage prevention: During the oil filtration process, the threaded connection at the top and bottom can effectively prevent oil leakage. Oil enters from the top adapter 40, passes through the disc filter element 10 for filtration, and then flows out from the bottom adapter 30. This tight threaded connection acts as a reliable barrier, ensuring that oil flows along the predetermined path during the entire filtration process and does not seep out of the interface. For example, in a high-pressure oil filtration system, if the interface is not sealed well, oil may be ejected under high pressure, causing safety hazards and oil waste. Proper sealing measures in conjunction with threaded connections can effectively prevent this situation.

[0087] Stable connection structure: During equipment operation, various vibrations and impact forces may occur, such as the operating vibration of the oil pump and the impact force caused by the pressure fluctuation of the oil in the pipeline. Threaded connections can tightly combine the top adapter 40, the bottom adapter 30, and the series connection pipe 201 of the corrugated filter element assembly 20, making the entire filter element structure more stable. This stable connection structure ensures that the filter element can still work normally under complex working conditions and does not affect the filtration effect due to loose connections.

[0088] Easy installation and removal

[0089] Easy to operate: Threaded connections are a relatively simple and intuitive connection method. When installing the filter element, the operator only needs to align the top series connection pipe 201 of the disc filter element 10 with the top adapter 40, and then rotate to complete the connection. The bottom connection is the same. This connection method does not require complex tools or special skills, and is convenient and fast. In contrast, methods such as welding or gluing not only require professional equipment and technology, but also make it very difficult to disassemble and reassemble if the connection fails.

[0090] Easy maintenance: When the filter element needs to be cleaned, parts replaced, or repaired, the advantages of threaded connections are more obvious. The top adapter 40 and the bottom adapter 30 can be easily removed from the series connection pipe 201, and then the corrugated filter element assembly 20 inside the filter element can be operated. For example, if the corrugated filter sheet 206 is clogged or damaged, it can be quickly disassembled and replaced, reducing equipment downtime and improving equipment maintenance efficiency.

[0091] Standardization and compatibility

[0092] Strong versatility: threaded connection is a standardized connection method widely used in the industry. This makes the disc filter 10 more easily compatible when connected to different pipeline systems or filtration equipment. As long as the interfaces of other equipment also adopt the corresponding thread standard, the filter can be easily connected to the system, improving the versatility and applicability of the filter.

[0093] Good interchangeability: if a component is damaged, it is very easy to replace the same specification component due to the standardization of threaded connection. This helps to reduce maintenance costs and quickly restore the normal operation of the equipment.

[0094] Embodiment 3

[0095] As shown in Figs. 1 to 3 , a corrugated disc filter includes a disc filter 10 spliced by multiple groups of corrugated filter assemblies 20, a top adapter 40 connected to the top of the disc filter 10, and a bottom adapter 30 connected to the bottom of the disc filter 10. The corrugated filter assembly 20 includes a series connection pipe 201, two groups of symmetrically distributed clamping grooves 204 are formed on the outer side of the series connection pipe 201, a sealing rubber ring 205 is sleeved on the clamping grooves 204, a corrugated filter sheet 206 is sleeved on the outer side of the series connection pipe 201 between the two groups of sealing rubber rings 205, a support sheet 207 is movably inserted into the corrugated filter sheet 206, one end of the support sheet 207 is inserted into the series connection pipe 201, a connecting block 202 is connected in the series connection pipe 201, the connecting block 202 is connected to the support sheet 207 through a first fixing wire 203, the sealing rubber ring 205 is connected to the support sheet 207 through a second fixing wire 208, the top of the series connection pipe 201 of the corrugated filter assembly 20 at the top of the disc filter 10 is detachably connected to the top adapter 40, and the bottom of the series connection pipe 201 of the corrugated filter assembly 20 at the bottom of the disc filter 10 is detachably connected to the bottom adapter 30.

[0096] The sealing rubber ring 205 is a rubber product.

[0097] The advantages of the above arrangement are:

[0098] Good sealing performance

[0099] The rubber material itself has excellent elasticity and softness. When the sealing rubber ring 205 is installed in the clamping groove 204 of the series connection pipe 201, it can tightly fit the clamping groove and the surface of the component in contact with it. Under the action of oil pressure, the rubber sealing rubber ring 205 will be elastically deformed, filling the small gap between the components, thereby effectively preventing oil leakage.

[0100] For example, during the filtration process, the oil liquid may exert pressure on the connection part in different directions. The rubber sealing ring 205 can adapt to such changes in pressure and always maintain good sealing performance, ensuring that the oil liquid can only flow in the predetermined filtration channel, thereby ensuring the accuracy and efficiency of the filtration.

[0101] Oil resistance

[0102] The filter core used for oil filtration requires that the sealing material can resist the corrosion of oil. Rubber products generally have good oil resistance and can work in an oil environment for a long time without being corroded or damaged.

[0103] Different types of rubber have different degrees of resistance to oil. In oil filtration applications, the appropriate rubber material can be selected according to the specific type of oil to make the sealing ring 205, so as to ensure that it can maintain stable performance in the corresponding oil and prolong the service life of the sealing ring 205.

[0104] Adapt to various working conditions

[0105] The rubber sealing ring 205 can adapt to a certain degree of vibration, temperature change, and size change of the parts. During the operation of the equipment, vibration may occur, and the elasticity of the rubber can buffer the impact of such vibration on the sealing effect.

[0106] At the same time, when the temperature changes, the rubber material can maintain its sealing performance within a certain range. Moreover, if the connecting parts change in size due to thermal expansion and contraction, the rubber sealing ring 205 can also adapt to such changes through its own elastic deformation and still maintain good sealing effect.

[0107] Easy to install and replace

[0108] The softness of the rubber sealing ring 205 makes it easy to install into the clamping groove 204 of the series connection pipe 201. The operator only needs to put it into the clamping groove to complete the installation, without the need for complex tools or special installation skills.

[0109] When the sealing ring 205 needs to be replaced due to aging or damage, it is also very convenient. The old sealing ring 205 can be quickly removed from the clamping groove, and then the new sealing ring 205 can be installed, which helps to reduce the equipment maintenance time and improve the operation efficiency of the equipment.

[0110] The corrugated filter core sheet 206 is a wood pulp cellulose product.

[0111] The advantages of the above arrangement are:

[0112] Good filtration performance

[0113] Micro-particle interception capability: Wood pulp cellulose has a fibrous microstructure that creates a large number of micro-pores and channels. When oil flows through the corrugated filter sheet 206, these pores and channels can effectively intercept tiny impurity particles in the oil, such as metal particles, dust, etc. For example, in the process of filtering lubricating oil, it can intercept metal shavings generated by wear, preventing these impurities from causing further wear to mechanical equipment.

[0114] Deep filtration effect: Due to its fiber interlacing characteristics, wood pulp cellulose products can achieve deep filtration. When oil passes through the filter sheet, impurity particles will be intercepted and adsorbed multiple times between the fibers, thereby improving the precision and efficiency of filtration and ensuring higher quality of filtered oil.

[0115] Renewable and environmentally friendly

[0116] Resource sustainability: Wood pulp is a renewable resource, mainly derived from wood. Compared with some synthetic materials, using wood pulp cellulose to make filter sheets is more sustainable in terms of resource utilization. Wood can be regenerated through proper forestry management, reducing dependence on non-renewable resources.

[0117] Environmental friendliness: After the service life of the filter sheet ends, wood pulp cellulose products are relatively easy to dispose of. It can decompose in the natural environment, causing less environmental pollution. Moreover, from the production process, the processing of wood pulp cellulose generally has less environmental impact than the production of some chemical synthetic materials.

[0118] Chemical stability and compatibility

[0119] Adaptability to oil: Wood pulp cellulose exhibits good chemical stability in an oil environment. It does not chemically react with most oils, does not release harmful substances into the oil, and does not decompose or deteriorate due to the chemical properties of the oil. This allows the corrugated filter sheet 206 to maintain stable performance in the filtration of different types of oil.

[0120] Good compatibility with other materials: Wood pulp cellulose can work well with other components in the filter, such as the sealing ring 205, the support sheet 207, and the series connection pipe 201, etc. It does not corrode or adversely affect other components, helping to maintain the stability and reliability of the entire filter system.

[0121] Cost-effective

[0122] Lower raw material cost: Wood pulp, as a widely used raw material, has a relatively low cost. Compared with some high-performance synthetic filtration materials, using wood pulp cellulose to make corrugated filter sheets 206 can reduce production costs while ensuring certain filtration performance, making the entire filter product more competitive in the market in terms of price.

[0123] Reasonable processing cost: The processing technology of wood pulp cellulose is relatively mature, and the processing cost is also reasonable. Through appropriate molding and processing methods, the wood pulp cellulose can be made into filter core sheets with corrugated structure, and the production efficiency is higher, which further optimizes the cost benefit.

[0124] The top and bottom of the corrugated filter core sheet 206 are provided with corrugated structures.

[0125] The advantages of the above arrangement are:

[0126] Increase the filtering area

[0127] Efficient use of space: The corrugated structure makes the surface of the filter core sheet not a flat plane, but a number of ups and downs. This wrinkle greatly increases the contact area of the filter core sheet and the oil. In the same filter core volume, the filter core sheet with corrugated structure can provide more filtering area than the flat filter core sheet. For example, when filtering oil containing a large amount of impurities, the larger filtering area means that more impurities can be intercepted, thereby improving the filtering efficiency.

[0128] Multi-level filtering: When the oil flows through the corrugated structure, it will flow along the ups and downs of the corrugated path. This allows the oil to be filtered in multiple layers inside the filter core sheet. Impurity particles have more opportunities to contact the fiber structure of the filter core sheet and be intercepted, further improving the filtering effect and effectively removing small particle impurities.

[0129] Enhance structural strength

[0130] Resistance to deformation: The corrugated structure makes the filter core sheet itself have a certain three-dimensional shape and supporting force. When the oil pressure acts on the filter core sheet, the corrugated structure can disperse the pressure, avoiding the deformation of the filter core sheet due to excessive local pressure. For example, in the case of high-pressure oil filtration, flat filter core sheets may be concave or damaged under pressure, while corrugated filter core sheets can better maintain their shape and filtering function.

[0131] Improved impact resistance: During equipment operation, there may be sudden changes in oil flow, pipe vibration, etc., which will impact the filter core sheet. The corrugated structure can enhance the impact resistance of the filter core sheet, so that it can still work stably under complex working conditions, prolonging the service life of the filter core sheet.

[0132] Optimize oil flow characteristics

[0133] Even distribution of oil: The corrugated structure can guide the oil to be more evenly distributed on the surface and inside the filter element. When the oil enters the filter element from the inlet adapter 40, the corrugations can cause the oil to be evenly dispersed to various parts of the filter element, avoiding the oil flowing in local areas. In this way, the filtering area of the entire filter element can be fully utilized, preventing the situation of over-filtering in some parts and under-utilization in other parts.

[0134] Reduced flow resistance: A reasonably designed corrugated structure can reduce the flow resistance of the oil in the filter element to some extent. The oil can flow smoothly along the natural path of the corrugations, rather than directly impacting the flat surface of the filter element, thereby reducing energy loss and enabling the oil to pass through the filter more efficiently.

[0135] The support sheet 207 is made of stainless steel.

[0136] The advantages of the above arrangement are:

[0137] Excellent mechanical properties

[0138] High strength and rigidity: Stainless steel has very high strength and rigidity. During the operation of the corrugated filter element 206, the support sheet 207 can provide stable support. When the oil pressure acts on the filter element, the stainless steel support sheet 207 can prevent the filter element from excessive deformation or damage. For example, in the environment of high-flow and high-pressure oil filtration, the support sheet 207 can withstand a large pressure, ensuring that the filter element maintains its shape and filtering function, thereby ensuring the stability and reliability of the filtration.

[0139] Good fatigue resistance: During the long-term operation of the equipment, the flow of oil will continuously exert pressure and vibration on the filter element. The stainless steel support sheet 207 has good fatigue resistance and can withstand such long-term cyclic loading without being prone to cracking or damage. This allows the filter element to maintain good performance during long-term use, reducing the risk of filter failure due to failure of the support structure.

[0140] Strong corrosion resistance

[0141] Adapt to oil environment: In oil filtration, the oil may contain some corrosive components. Stainless steel material has good resistance to most corrosive substances in the oil. It is not as easily corroded as some ordinary metals, thereby ensuring the structural integrity and service life of the support sheet 207. For example, for lubricating oil or fuel containing trace amounts of acidic substances, the stainless steel support sheet 207 can effectively resist its corrosion, ensuring the long-term stable operation of the filter element.

[0142] Increased durability: Due to its corrosion resistance, the stainless steel support sheet 207 can maintain good performance in various complex oil filtration environments. Even in humid or chemical environments, it will not easily rust or be corroded, reducing the frequency of replacing the support sheet and reducing maintenance costs.

[0143] Good temperature adaptability

[0144] Wide temperature range operation: Stainless steel can maintain its mechanical properties within a wide temperature range. In some special oil filtration scenarios, such as high-temperature lubricating oil systems or low-temperature fuel filtration systems, temperature changes are large. The stainless steel support sheet 207 can work normally under these different temperature conditions and will not soften or become brittle due to temperature changes, thereby providing stable support for the filter sheet.

[0145] Heat conduction performance assistance: Stainless steel has certain heat conduction performance. In some filtration systems that require temperature control, the support sheet 207 can help heat transfer within the filter core, which is conducive to maintaining stable oil temperature and improving filtration efficiency.

[0146] Easy to clean and maintain

[0147] Smooth surface characteristics: The surface of stainless steel is relatively smooth and impurities are not easily attached. When the filter core needs to be cleaned and maintained, impurities on the support sheet 207 can be easily removed. This makes maintenance work more convenient and efficient, reducing maintenance time and workload. For example, when cleaning the filter core, oil stains and impurities on the surface of the support sheet 207 can be easily wiped or rinsed off.

[0148] The examples made by the utility model are not a limitation on the implementation mode. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description, and all implementation modes do not need to be exhausted here, and the obvious changes or variations derived therefrom are still within the protection scope of the utility model.
