Description

Technical Field

[0001] This utility model belongs to the field of oil pump technology, and specifically relates to a novel oil pump assembly. Background Technology

[0002] Gear oil pumps are suitable for conveying various lubricating liquids at temperatures not exceeding 70℃. For high-temperature applications up to 200℃, high-temperature resistant materials can be used. This pump is not suitable for conveying corrosive liquids, liquids containing hard particles or fibers, highly volatile liquids, or liquids with low flash points, such as gasoline and benzene.

[0003] Existing gear oil pumps require filtering impurities from the oil during transport to prevent internal blockage. However, existing filtration devices require disassembly for cleaning and maintenance, which is inconvenient, time-consuming, labor-intensive, and disrupts the normal operation of the gear oil pump. Therefore, this application provides a high-pressure gear oil pump to meet this requirement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel oil pump assembly with easy-to-disassemble filter.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel oil pump assembly, comprising a pump body and front and rear covers on both sides of the pump body, wherein a drive shaft is provided on the upper part of the pump body, and a bevel gear is provided at the front end of the drive shaft, characterized in that a driving gear and a driven gear are provided in the pump body, and the driving gear is sleeved on the drive shaft, and an oil inlet and an oil outlet are provided at both ends of the pump body, wherein a filter assembly is provided on the oil inlet, the filter assembly comprising a support frame and a filter screen, an opening groove is provided in the support frame, and a snap-fit ​​unit is provided in the opening groove, and a snap-fit ​​groove is provided on the pump body at the snap-fit ​​unit.

[0006] In the aforementioned novel oil pump assembly, the snap-fit ​​unit is provided with a snap-fit ​​block that fits into the snap-fit ​​groove, and the top of the snap-fit ​​block has an elastic button. The bottom of the snap-fit ​​block is provided with a base located in the opening groove, and a return spring with an elastic reset function is provided under the base. A limiting groove for fixing the return spring is provided at the bottom of the base.

[0007] In the aforementioned novel oil pump assembly, the pump body has a concave groove at the upper port of the snap-fit ​​groove.

[0008] Compared with existing technologies, this new type of oil pump assembly has a filter component designed in front of the oil inlet of the gear oil pump to ensure the purity of the liquid medium entering the pump body; the filter component is equipped with a detachable snap-fit ​​unit, which facilitates later cleaning or replacement and improves working efficiency.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, the novel oil pump assembly includes a pump body 1 and front and rear covers 2 and 3 on both sides of the pump body 1. A drive shaft 4 is installed inside the pump body 1, and a bevel gear 5 is installed at the front end of the drive shaft 4. A drive gear 6 and a driven gear 7 are installed inside the pump body 1, and the drive gear 6 is sleeved on the drive shaft 4. An oil inlet 8 and an oil outlet 9 are opened at both ends of the pump body 1. A filter assembly is installed on the oil inlet 8. The filter assembly includes a support frame 10 and a filter screen 11. The purity of the liquid is improved by adding a filter assembly to the oil inlet 8. An opening groove 12 is opened in the support frame 10, and a snap-fit ​​unit 13 is installed in the opening groove 12. A snap-fit ​​groove 14 is opened at the snap-fit ​​unit 13 of the pump body 1. The snap-fit ​​unit 13 is installed in the snap-fit ​​groove 14 to prevent the filter assembly from falling off due to the flow of liquid.

[0015] To elaborate further, the snap-fit ​​unit 13 is provided with a snap-fit ​​block 15 that fits into the snap-fit ​​groove 14, and the snap-fit ​​block 15 has an elastic button 16 on its top. The bottom of the snap-fit ​​block 15 is provided with a base 17 located in the opening groove 12. A reset spring 18 with elastic reset function is provided under the base 17, and a limiting groove 19 for fixing the reset spring 18 is provided at the bottom of the base 17.

[0016] To elaborate further, when inserting the filter assembly into the oil inlet 8, first press the elastic button 16 to fully insert the snap-fit ​​unit 13 into the opening groove 12. This inserts the filter assembly deep into the oil inlet 8. After insertion, locate the snap-fit ​​groove 14 and place the snap-fit ​​unit 13 below it. Then, fully insert the snap-fit ​​block 15 into the snap-fit ​​groove 14 to secure the filter assembly. When replacement or maintenance is required, press the elastic button 16 with one hand and use the other hand to reach into the oil inlet 8, clamp the filter assembly, and slowly pull it out.

[0017] To elaborate further, the pump body 1 has a concave groove 20 at the upper end of the snap-fit ​​groove 14, which facilitates pressing the elastic button 16 inside the snap-fit ​​groove 14.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as pump body 1, pump body front cover 2, pump body rear cover 3, drive shaft 4, bevel gear 5, driving gear 6, driven gear 7, oil inlet 8, oil outlet 9, support frame 10, filter screen 11, opening groove 12, snap-fit ​​unit 13, snap-fit ​​groove 14, snap-fit ​​block 15, elastic button 16, base 17, return spring 18, limit groove 19, and concave groove 20, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
