Description

TECHNICAL FIELD

[0001] The utility model relates to pressure stabilizer technical field, concretely is a kind of light weight compact oil circuit pressure stabilizer. BACKGROUND

[0002] In hydraulic system, pressure stabilizer is one of the key components to ensure the stable operation of oil circuit system. The traditional pressure stabilizer usually adopts counterweight or spring as the main means of pressure regulation, to compensate for the change of oil pressure caused by factors such as temperature change, load fluctuation, and maintain the normal working pressure of the system.

[0003] However, these traditional designs have certain limitations. The pressure stabilizer using counterweight needs a larger space to accommodate the weight block and its related mechanism, which makes the whole device relatively bulky and occupies a large space, not suitable for installation in limited space application scenarios. The traditional design is often limited by its mechanical structure, and it is difficult to achieve a wide range of pressure adjustment. Especially when the system requires accurate and fast response, the spring or counterweight method is not up to the task. With the passage of time, impurities generated by mechanical wear in hydraulic oil will gradually accumulate and may cause system performance degradation. After entering the pressure stabilizer, it will exacerbate the wear of the pressure stabilizer and affect its service life. Therefore, a light weight compact oil circuit pressure stabilizer is needed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a kind of light weight compact oil circuit pressure stabilizer, with the advantages of wider pressure regulating range and accurate pressure control, solving the problems of large volume, heavy weight, inconvenient pressure regulation and complex maintenance of traditional pressure stabilizer.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a kind of light weight compact oil circuit pressure stabilizer, including pressure stabilizing sleeve and pressure stabilizing piston, the pressure stabilizing sleeve is provided with pressure regulating assembly, and the pressure stabilizing sleeve is provided with oil filter cartridge in;

[0006] The pressure stabilizing sleeve is provided with piston chamber and filter chamber, the upper end of the piston chamber is provided with pressure regulating chamber, the lower end of the filter chamber is provided with maintenance chamber, the pressure stabilizing piston includes piston rod and piston head, the piston head is fixedly installed at the lower end of piston rod, the piston head is installed in piston chamber and is slidably connected with pressure stabilizing sleeve, the oil filter cartridge is detachably installed at the bottom of filter chamber, the side end surface of filter chamber is provided with oil inlet pipe, the pressure regulating assembly includes first electromagnet and second electromagnet, the first electromagnet is fixedly installed at the top of piston rod, and the second electromagnet is fixedly installed at the lower end surface of the top of pressure stabilizing sleeve and opposite to the first electromagnet.

[0007] As a preferred light weight compact oil circuit pressure stabilizer of the utility model, the top of the pressure stabilizing sleeve is provided with pressure regulating switch electrically connected with the first electromagnet and the second electromagnet.

[0008] As a preferred embodiment of the lightweight and compact oil circuit regulator of this utility model, the oil filter cartridge includes an outer cylinder, a filter screen and a base. The outer cylinder is fixedly installed on the base. A first through hole is provided on the side wall of the outer cylinder, and a second through hole is provided on the top of the outer cylinder. The filter screen is fixedly installed on the top of the inner end face of the outer cylinder.

[0009] As a preferred embodiment of the present invention, the base has an external thread on its side end face, the base is inserted into the filter chamber and threadedly connected to the pressure regulating sleeve, and a storage cavity is formed between the outer cylinder and the filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a pressure regulating component consisting of a first electromagnet and a second electromagnet to replace the traditional counterweight or spring structure, solving the problems of large size, heavy weight, and limited pressure regulating range of traditional pressure regulators. The first electromagnet is fixed to the top of the piston rod, and the second electromagnet is set opposite to the top of the pressure regulating sleeve. The electromagnetic force between the two is steplessly adjusted by the pressure regulating switch, directly controlling the balance position of the pressure regulating piston. This structure makes the device more compact and lightweight, while achieving a wider pressure regulating range and precise stepless pressure regulation, adapting to the needs of different hydraulic systems, and is especially suitable for complex oil circuit environments with limited space.

[0015] 2. This utility model effectively solves the problem of accelerated wear of the pressure regulator caused by metal debris in hydraulic oil through the layered structure design of the oil filter cartridge. The filter screen intercepts impurities generated by oil circuit wear, and the storage chamber uses gravity to collect debris. The limiting flange and annular flange force the oil to flow through the filter screen and enhance the interception effect, preventing impurities from entering the piston chamber and causing wear. The base adopts a threaded connection and is equipped with a knob, which can be manually disassembled without tools. Combined with the maintenance chamber design, it significantly simplifies the filter residue cleaning and maintenance process, extends the service life of the device, and ensures long-term stable operation of the oil circuit.

[0023] Please see Figures 1-6 A lightweight and compact oil circuit pressure regulator includes a pressure regulating sleeve 1 and a pressure regulating piston 2. The pressure regulating sleeve 1 is provided with a pressure regulating component 3, and the pressure regulating sleeve 1 is provided with an oil filter cartridge 4.

[0024] The pressure stabilizing sleeve 1 is provided with a piston chamber 101 and a filter chamber 102. The upper end of the piston chamber 101 is provided with a pressure regulating chamber 104, and the lower end of the filter chamber 102 is provided with a maintenance chamber 105. The pressure stabilizing piston 2 includes a piston rod 201 and a piston head 202. The piston head 202 is fixedly installed at the lower end of the piston rod 201 and is installed in the piston chamber 101 and slidably connected to the pressure stabilizing sleeve 1. The oil filter cartridge 4 is detachably installed at the bottom of the filter chamber 102. The side end face of the filter chamber 102 is provided with an oil inlet pipe 103. The pressure regulating component 3 includes a first electromagnet 301 and a second electromagnet 302. The first electromagnet 301 is fixedly installed at the top of the piston rod 201, and the second electromagnet 302 is fixedly installed at the lower end face of the top of the pressure stabilizing sleeve 1 and is opposite to the first electromagnet 301.

[0025] By replacing the traditional counterweight-based voltage stabilization and buffering method with the first electromagnet 301 and the second electromagnet 302, the space occupied is greatly saved, the compactness of the voltage regulator is improved, and the weight of the equipment is reduced. Compared with the spring-type voltage stabilization and buffering method, it also saves space and has a larger pressure adjustment range, which can adapt to oil circuit systems with different oil pressures.

[0026] Furthermore, a voltage regulating switch 303 is provided on the top of the voltage stabilizing sleeve 1, which is electrically connected to the first electromagnet 301 and the second electromagnet 302.

[0027] The voltage of the first electromagnet 301 and the second electromagnet 302 is adjusted by the voltage regulating switch 303, thereby changing the interaction force between the first electromagnet 301 and the second electromagnet to meet the needs of different oil circuit pressures, and the stepless speed regulation is more precise.

[0028] Furthermore, the oil filter cartridge 4 includes an outer cylinder 401, a filter screen 402, and a base 403. The outer cylinder 401 is fixedly installed on the base 403. A first through hole 4011 is provided on the side wall of the outer cylinder 401, and a second through hole 4012 is provided on the top of the outer cylinder 401. The filter screen 402 is fixedly installed on the top of the inner end face of the outer cylinder 401.

[0029] During long-term use, a small amount of worn metal powder may be mixed into the hydraulic oil circuit. This powder is intercepted by the filter screen 402 and enters the piston cavity, aggravating the wear of the pressure regulator.

[0030] Furthermore, the side end face of the base 403 is provided with external threads. The base 403 is inserted into the filter chamber 102 and threadedly connected to the pressure stabilizing sleeve 1. A storage cavity 405 is formed between the outer cylinder 401 and the filter screen 402.

[0031] The metal debris intercepted by the filter screen 402 settles to the bottom of the storage chamber 405 under the action of gravity. The threaded base 403 structure makes it easy to remove the oil filter cartridge 4 to clean the filter residue.

[0032] Furthermore, a knob 404 is provided on the lower end face of the base 403.

[0033] The base 403 can be easily rotated manually using the knob 404 to remove the oil filter cartridge 4 without the need for external tools, making it convenient for the voltage regulator to be inspected and maintained.

[0034] Furthermore, the inner end face of the filter chamber 102 is provided with a limiting flange 1021 that fits against the top of the oil filter cartridge 4.

[0035] The insertion stroke of the oil filter cartridge 4 is limited by the limiting flange 1021, while preventing hydraulic oil from flowing from the outer end face of the outer cylinder 401. This forces the hydraulic oil to pass through the first through hole 4011, the filter screen 402, and then through the second through hole 4012, thus improving the filtration effect.

[0036] Furthermore, an annular flange 4013 is provided on the inner end face of the first through hole 4011.

[0037] The annular flange 4013 increases the interception effect of the oil filter cartridge 4 on the filter residue, making it easier for metal debris to enter the outer cylinder 401 and less likely to flow out, thus improving the interception effect and facilitating the removal of metal debris during maintenance.

[0038] In use, the device first connects the oil inlet pipe 103 to the oil circuit of the hydraulic equipment. Hydraulic oil enters the oil filter cartridge 4 at the bottom of the filter chamber 102 through the oil inlet pipe 103. The oil then enters the inner cavity of the outer cylinder 401 through the first through hole 4011 on the side wall of the outer cylinder 401. The filter screen 402 intercepts metal debris in the hydraulic oil and causes it to settle at the bottom of the storage chamber 405. The filtered oil then flows into the piston chamber 101 through the second through hole 4012 at the top of the outer cylinder 401. Next, the oil entering the piston chamber 101 pushes the piston head 202 and piston rod 201 upwards. This connects the first electromagnet 301 and the second electromagnet 302 to an external power source via the pressure regulating switch 303. The first electromagnet 301 at the top of the piston rod 201 is connected to the top of the pressure stabilizing sleeve 1. The second electromagnet 302 generates electromagnetic repulsion. By adjusting the voltage difference between the two electromagnets through the top pressure regulating switch 303, the magnitude of the electromagnetic repulsion is dynamically adjusted to balance the oil pressure. When the oil pressure changes, the piston rod 201 moves up and down under the action of electromagnetic force and oil pressure, and the piston head 202 slides in the piston chamber 101 to stabilize the oil pressure. When maintenance is required after long-term use, the equipment is inverted and the oil circuit is cut off. The knob 404 at the lower end of the base 403 is manually rotated to unscrew the oil filter cartridge 4 from the bottom of the filter chamber 102 through the external thread. After cleaning the metal debris in the filter screen 402 and the storage chamber 405, the filter cartridge 4 is reinstalled. The limiting flange 1021 ensures that the oil filter cartridge 4 is correctly positioned, and the annular flange 4013 enhances the interception effect. The maintenance chamber 105 facilitates operation.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
