[0002] Some pump bodies rely on oil mist lubrication system to guarantee its smooth operation. However, when the oil mist lubrication system is not equipped with a heat tracing device, the oil collecting speed of the oil collecting box becomes faster under the condition of low winter temperature, because the viscosity of the lubricating oil increases in the low temperature environment, and then the oil mist is more likely to gather in the oil collecting box.

[0027] When the embodiments give numerical ranges, it should be understood that unless the embodiments expressly state otherwise, every numerical range is a subset of every wider numerical range encompassed therein. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this technology pertains, and any methods and materials equivalent or similar to those described herein can be used in the practice or testing of the technology.

[0028] In the field of chemical production, there is a set of extraction devices, whose nominal scale is set to process several million tons of material per year. This large-scale device plays a crucial role in the internal OH2 pump during operation, and the oil mist lubrication system of the pump uses a complete oil mist distribution pipeline.

[0029] This special oil mist distribution pipeline design is originally to achieve more accurate and uniform distribution of lubricating oil mist, to ensure that all key parts of the pump, such as bearings, can be fully lubricated, thereby ensuring the stable operation of the pump. However, the main pipeline of the entire oil mist lubrication system is not equipped with a heating device.

[0030] In cold winter, the temperature is low, which leads to a series of problems. Because there is no heating to maintain the oil temperature, the flowability of the lubricating oil will be significantly reduced, and the oil in the oil collecting box 3 will be more prone to condensation and accumulation. Over time, the oil collecting speed in the oil collecting box 3 will be significantly accelerated.

[0031] In this case, if the operator fails to perform the oil discharge operation in time or the first oil discharge pipe 22 is blocked, the consequences will be very serious. On the one hand, the oil mist return in the bearing box 2 will be not smooth, because too much oil accumulation in the oil collecting box 3 will hinder the normal circulation loop of the oil mist, so that part of the oil mist cannot return to the bearing box 2 smoothly, thereby causing the imbalance of the lubrication system, on the other hand, there is also the risk of misoperation, that is, the operator may accidentally close the oil mist lubrication inlet valve 111, once this valve is closed, new oil mist cannot enter the lubrication system, and the bearing and other components will not be adequately lubricated.

[0032] Whether the oil mist return is not smooth or the oil mist lubrication inlet valve 111 is accidentally closed, it will cause the oil mist lubrication effect of the bearing to deteriorate sharply. As one of the core components of the pump, the bearing needs good lubrication during high-speed operation to reduce friction and wear, once the lubrication is insufficient, the bearing will bear greater pressure and friction, which is likely to cause the bearing to overheat, wear out and even damage. The damage of the bearing not only affects the normal operation of the pump, but also may cause the production of the entire extraction device to be interrupted, which brings huge economic losses and safety hazards to the enterprise.

[0033] Please refer to Figure 1 The utility model provides a pump body lubricating system, including oil mist distributor 1, bearing box 2 and oil collecting box 3, oil mist distributor 1 supplies oil mist through oil mist supply pipe 11, be provided with oil mist lubrication import valve 111 on oil mist supply pipe 11, bearing box 2 is communicated with oil mist distributor 1 through first pipeline 21,

[0034] Oil collecting box 3 is communicated with oil mist distributor 1 through second pipeline 31, be provided with oil outlet 32 on oil collecting box 3, wherein, bearing box 2 is drained to oil collecting box 3 through first oil drain pipe 22, be provided with second valve 221 on first oil drain pipe 22, still be provided with oil mist oil return pipe 23 between bearing box 2 and oil collecting box 3, be provided with third valve 231 on oil mist oil return pipe 23.

[0035] It should be noted that the oil mist distributor 1 is a device for converting lubricating oil into fine oil mist and uniformly distributing it to various lubrication points of mechanical equipment. The oil mist distributor 1 uses compressed air as a power source to convert lubricating oil into fine oil mist particles through a special atomizing device. These oil mist particles are suspended in the air and transported to various parts of the mechanical equipment that need to be lubricated with the airflow; for example, part of the oil mist distributor 1 generally includes an atomizing device, a compressed air system, a distribution pipeline network and a control valve; the atomizing device is the core component of the oil mist distributor 1, responsible for atomizing the lubricating oil into fine oil mist particles. Common atomizing devices include ultrasonic atomizers, pressure atomizers, etc. The compressed air system provides a power source, usually including an air compressor, an air tank and a pressure regulating valve, etc. The compressed air provides stable pressure and flow for the atomizing device after pressure regulation. The distribution pipeline network transports the atomized oil mist to various lubrication points of the mechanical equipment, and the design of the distribution pipeline network needs to be reasonably laid out according to the specific structure and lubrication requirements of the mechanical equipment to ensure that the oil mist can uniformly reach each lubrication point. The control valve is used to adjust the flow and pressure of the oil mist to adapt to different lubrication requirements, and the control valve can automatically or manually adjust the supply of oil mist according to the preset parameters. The bearing box 2 is the bearing box 2 of the pump body, used to support and accommodate the bearing assembly, usually located at the key position of the pump body, the bearing box 2 is a component in mechanical equipment used to support and position bearings, it is usually a closed or semi-closed box 201 structure, with bearings inside and connected to the power transmission components (such as shaft) of the pump body. The oil collecting box 3 is a device for collecting waste oil, the oil collecting box 3 includes a certain capacity to accommodate the collected waste oil. Its shape and size may vary depending on the specific application, but is usually designed as a rectangular or other shape suitable for the installation space. The oil outlet 32 is provided on the oil collecting box 3 for periodic discharge of accumulated oil, and the operator can clean the waste oil in the oil collecting box 3 by opening the oil outlet 32. It should be understood that the first pipeline 21, the second pipeline 31, the first oil discharge pipe 22 and the oil mist oil return pipe 23 are each provided with at least one.

[0036] In the case, the oil mist distributor 1 provides oil mist to the oil mist distributor 1 through the oil mist supply pipe 11, and the oil mist supply pipe 11 is provided with an oil mist lubrication inlet valve 111 for adjusting the flow and pressure of the oil mist, so that the oil mist can be uniformly distributed to each part needing lubrication; the bearing box 2 is communicated with the oil mist distributor 1 through the first pipeline 21. The bearing box 2 is an important part for storing and supporting bearings, and it receives oil mist from the oil mist distributor 1 through the first pipeline 21 to realize lubrication and cooling of the bearings; the oil collecting box 3 is communicated with the oil mist distributor 1 through the second pipeline 31. The oil collecting box 3 is used for collecting excess oil mist and lubricating oil discharged from the bearing box 2 to prevent them from accumulating too much in the bearing box 2. The oil collecting box 3 is provided with an oil discharge port 32 for periodically discharging accumulated oil; the first oil discharge pipe 22 connects the bearing box 2 and the oil collecting box 3, and is used for discharging oil mist and lubricating oil in the bearing box 2 into the oil collecting box 3; the second valve 221 (such as an oil collecting box 3 oil discharge valve) is arranged on the first oil discharge pipe 22, and an operator can adjust the oil discharge speed by controlling the valve; the oil mist oil return pipe 23 is arranged between the bearing box 2 and the oil collecting box 3, and is used for returning the oil mist that cannot be discharged in time back to the oil collecting box 3, which helps to avoid the problem of poor oil mist return of the bearing box 2 due to the operator's untimely oil discharge. The third valve 231 is installed on the oil mist oil return pipe 23, and is used for controlling the flow and pressure of the oil mist oil return. When the oil mist oil return pipe 23 needs to be used, the original oil return valve (i.e. the second valve 221) can be closed, and then lubricating oil is added to the bearing box 2 through the oil supplement port 204 of the bearing box 2 or the oil supplement port 204 of the bearing box 2 is waited for oil mist condensate to accumulate; the liquid level oil throwing ring 203 can bring the lubricating oil to the bearing for lubrication, and can be flexibly used according to the device condition; in summary, the improved lubricating oil circuit of the centrifugal pump is provided, the oil mist oil return pipe 23 and the corresponding control valve are added, the problems of fast oil collecting speed of the oil collecting box 3, untimely oil discharge of the operator and misoperation of closing the oil mist lubrication inlet valve 111 in winter are effectively solved, and the risk of damaging the bearings in the bearing box 2 is avoided or reduced.

[0037] Please refer to Figure 1 As an optional embodiment of the present application, the communication position of the oil mist oil return pipe 23 and the bearing box 2 is higher than the communication position of the first oil discharge pipe 22 and the bearing box 2.

[0038] It should be noted that the communication position of the oil mist return pipe 23 with the bearing box 2 is higher than the connection position of the first oil drain pipe 22 with the bearing box 2, for example, the oil mist return pipe 23 communicates with the oil supplement port 204 of the bearing box 2, and the oil supplement port 204 is higher than the connection position of the first oil drain pipe 22 with the bearing box 2, so that the smoothness of the oil mist return pipe 23 can be better guaranteed. When the oil mist completes the lubrication mission of the bearing and other components in the bearing box 2, part of the oil mist may not be able to be discharged in time due to various reasons. In winter, the flowability of the lubricating oil becomes poor, and this situation is particularly obvious. At this time, if these oil mists accumulate in the bearing box 2, not only will it occupy limited space and affect the entry and distribution of fresh oil mist, but also it may cause the abnormal increase of the air pressure in the bearing box 2, thereby affecting the stability and reliability of the entire lubrication system; when the first oil drain pipe 22 is blocked, the communication of the oil mist return pipe 23 with the oil supplement port 204 of the bearing box 2 can provide a channel for the accumulated oil mist. They can flow back along the oil mist return pipe 23 to avoid accumulation in the bearing box 2, and ensure that there is always enough space in the bearing box 2 to receive new and clean oil mist, and maintain a good lubrication environment. In the actual production process, the operator may not be able to perform the oil draining operation in time due to various reasons, or it is difficult to accurately control the timing and amount of oil draining in some special situations, and through the communication of the oil mist return pipe 23 with the oil supplement port 204, even in the case of untimely oil draining, the accumulated oil mist can automatically flow back to the oil collecting box 3; this not only reduces the workload of the operator, but also reduces the risk of lubrication system failure caused by human operation errors. In addition, the returned oil mist can enter the lubrication cycle again, mix with fresh lubricating oil mist, and continue to provide lubrication for bearings and other components, which not only reduces the waste of lubricating oil, but also ensures that the bearings are always adequately lubricated, prolongs the service life of the bearings, and reduces the production cost of the enterprise.

[0039] Please refer to Figures 2-3 , as an optional embodiment of the present case, the bearing box 2 comprises a box body 201 and a rotating shaft 202 arranged in the box body 201, and the rotating shaft 202 is provided with a liquid level oil throwing ring 203.

[0040] It should be noted that the bearing box 2 is a crucial component of the pump body lubrication system, and the bearing box 2 mainly includes a box body 201 and a rotating shaft 202 arranged in the box body 201, and the rotating shaft 202 is rotatably connected with the box body 201. On the rotating shaft 202, a liquid level oil throwing ring 203 is arranged. The liquid level oil throwing ring 203 is usually located on the side of the rotating shaft 202 close to the inner wall of the bearing box 2, and its function is to throw the excess lubricating oil accumulated at the bottom of the bearing box 2, so as to form oil mist or oil droplets, and then uniformly distribute these oil mist or oil droplets in various parts of the bearing box 2, including the bearing surface, the surface of the rotating shaft 202 and other parts needing lubrication. When the rotating shaft 202 starts to rotate, the liquid level oil throwing ring 203 will rotate at high speed with the rotating shaft 202, and due to the special shape and structure design of the liquid level oil throwing ring 203, it can effectively capture the lubricating oil at the bottom of the bearing box 2 and throw it up. The thrown lubricating oil will form fine oil droplets and oil mist under the action of centrifugal force, and these oil droplets and oil mist will be brought to all corners of the bearing box 2 with the flow of air and the rotation of the rotating shaft 202, realizing comprehensive lubrication of all parts. In addition, the liquid level oil throwing ring 203 can also adjust the oil level height in the bearing box 2 to a certain extent. When the oil level in the bearing box 2 is too high, the liquid level oil throwing ring 203 will throw away the excess lubricating oil, so that it returns to the oil collecting box 3; and when the oil level is too low, the liquid level oil throwing ring 203 can fully utilize the small amount of lubricating oil accumulated at the bottom of the box, ensuring that the bearing can always be sufficiently lubricated. This self-regulating function makes the lubrication state in the bearing box 2 more stable and reliable, reducing the lubrication risk caused by oil level fluctuation. When the oil mist return pipe 23 is in use, the original first oil drain pipe 22 can be closed, and when lubricating oil is added to the bearing box 2 through the oil supplementing port 204 of the bearing box 2 or the oil mist condensate self-accumulates to the oil supplementing port 204 of the bearing box 2, the liquid level oil throwing ring 203 can bring the lubricating oil to the bearing for lubrication, and can be flexibly used according to the device condition.

[0041] As an optional embodiment of the present case, the oil mist lubrication inlet valve 111 has multiple valve positions, including a closed valve position, a running valve position and a maintenance valve position.

[0042] It should be noted that the closing valve position is used when the device is in a stop state or does not need to be lubricated, at which position the oil mist lubrication inlet valve 111 is fully closed, cutting off the passage between the oil mist supply pipe 11 and the oil mist distributor 1, and preventing any oil mist from entering the lubrication system. The running valve position is a valve position frequently used during normal operation of the device. When the device starts and begins to run, the operator will adjust the oil mist lubrication inlet valve 111 to the running valve position, at which position the valve is opened to a suitable opening degree, allowing oil mist to enter the oil mist distributor 1 through the oil mist supply pipe 11 at a stable and precise flow rate. This opening degree is determined by strict calculation and debugging according to the speed, load and lubrication requirements of the bearings and other components of the device, ensuring that the oil mist can form a uniform and appropriate lubricating film in the bearing box 2, providing good lubrication and cooling for the shaft 202 and bearings, reducing friction and wear, and ensuring the smooth operation of the device. The maintenance valve position is a valve position specially set to meet the maintenance needs of the device. Before performing maintenance work on the device, the operator will first switch the oil mist lubrication inlet valve 111 to the maintenance valve position. At this valve position, the opening degree of the valve is adjusted to a specific small value, so that only a small amount of oil mist enters the lubrication system. The purpose of this is to maintain a certain lubrication environment in the bearing box 2 during maintenance, prevent damage to components due to long-term exposure without lubrication, and avoid excessive oil mist affecting the progress of maintenance work. For example, when checking, cleaning or replacing bearings, the maintenance valve position can ensure that the bearing surface is always protected by a thin oil film, while not making the maintenance work complicated and difficult due to the presence of a large amount of oil mist.

[0043] Please refer to Figure 1 As an optional embodiment of the present application, the upper part of the oil collecting box 3 is provided with an oil mist recovery pipeline 33, and a fourth valve 331 is arranged on the oil mist recovery pipeline 33. The oil mist recovery pipeline 33 can realize the recovery of oil mist in the oil collecting box 3.

[0044] It should be noted that because oil mist has higher cleanliness and higher recycling value compared to liquid oil, the setting of the oil mist recovery pipeline 33 can realize the recovery and reuse of oil mist in the oil collecting box 3. The pipe diameter of the oil mist recovery pipeline 33 is moderate, which can ensure the smooth flow of oil mist therein, and will not occupy too much space due to too large pipe diameter, or cause too large flow resistance of oil mist due to too small pipe diameter. The fourth valve 331 is arranged on the oil mist recovery pipeline 33, and the operator can accurately adjust the opening degree of the fourth valve 331 through the control system when it is necessary to recover the oil mist in the oil collecting box 3; the opening degree of the valve can be flexibly adjusted according to the amount of oil mist in the oil collecting box 3 and the recovery requirements, so as to realize accurate control of the oil mist recovery amount.

[0045] The oil mist recovery pipeline 33 can realize efficient recovery of oil mist in the oil collecting box 3. When the oil mist in the bearing box 2 enters the oil collecting box 3 through various channels, the oil mist recovery pipeline 33 will suck the oil mist in the oil collecting box 3 into the pipeline under the action of negative pressure. In the pipeline, the oil mist will flow with the airflow and finally be transported back to the oil mist distributor 1 or other designated treatment equipment for further treatment and reuse, which not only can effectively reduce the emission of oil mist and reduce the pollution to the environment, but also can improve the utilization rate of lubricating oil and reduce the production cost of enterprises. In addition, in order to ensure the smoothness of the oil mist recovery pipeline 33, filter devices and cleaning interfaces are also arranged at some key positions of the pipeline. The filter devices can prevent impurities and particles from entering the pipeline and prevent them from clogging the pipeline or damaging the subsequent treatment equipment.

[0046] As an optional embodiment of the present case, the bearing box 2 is provided with a sight glass.

[0047] It should be noted that the installation position of the sight glass is usually located at a suitable viewing angle of the bearing box 2, so that the operator can conveniently and clearly observe the working condition in the box body 201. The sight glass is generally made of high-strength and transparent materials, such as special tempered glass or high-performance plastic, which can withstand the complex working environment in the bearing box 2, including high temperature, high pressure and corrosion of lubricating oil, and also can ensure good light transmission, so that the operator can clearly see each component in the box body 201.

[0048] Please refer to Figure 1 As an optional embodiment of the present case, the oil discharge port 32 includes a second oil discharge pipe 321 and a fifth valve 322 arranged on the second oil discharge pipe 321, so as to facilitate the oil collecting box 3 to discharge oil as required.

[0049] As an optional embodiment of the present case, the oil mist recovery pipeline 33 communicates with the oil mist supply pipe 11 or an oil mist supply source, and an oil pump is arranged between the communication position of the oil mist supply pipe 11 and the oil mist recovery pipeline and the oil mist lubrication inlet valve 111.

[0050] The oil mist recovery pipeline 33 is communicated with the oil mist supply pipeline 11 or an oil mist supply source, and forms a closed lubricating system, aiming at realizing efficient recycling of lubricating oil.

[0051] Referring to Figures 1-3 The utility model provides a pump body, including the pump body lubricating system, can use the pump body of pump body lubricating system of the utility model all may.

[0052] Referring to Figures 1-3 As an optional embodiment of the utility model, the body is a single-stage cantilever pump, such as a single-stage cantilever pump of foot mounting type or a single-stage cantilever pump of center line mounting type.

[0053] In summary, the utility model effectively overcomes some practical problems in the prior art, thereby having high utilization value and use significance.

[0054] The above embodiments only exemplarily illustrate the principle and effect of the utility model, and are not used for limiting the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
