[0002] An oil pump is a mechanical device that is usually used to transport liquids (such as petroleum, diesel or lubricating oil) from one location to another. Oil pumps are widely used in the fields of petrochemicals, machinery manufacturing, transportation, etc. Their main function is to transport liquids stored in the oil tank to the engine, lubrication system, gearbox and other equipment to maintain the normal operation of these equipment. Oil pumps are usually divided into three categories: in-line, distributed and single-unit, and require a power source to operate.

A plurality of filter holes 47 are provided on one side of the inner wall of the rectangular filter frame 45. An oil inlet 43 is provided on one side of the filter cover 41, and an oil outlet 44 is provided on the other side of the filter cover 41. One side of the oil outlet 44 is located at one end of the oil inlet channel 33, and a plurality of filter holes 47 are located on the other side of the oil outlet 44. An oil inlet groove 46 is provided on one side of the rectangular filter frame 45, and the oil inlet groove 46 is located on one side of the oil inlet 43. A pipe connector 42 is installed on one side of the filter cover 41, and the pipe connector 42 is located on the other side of the oil inlet 43.

[0022] In this embodiment, through the cooperation of the pipe connector 42, the oil inlet 43 and the oil inlet groove 46, it is convenient to discharge the oil inside the external oil pipe into the rectangular filter frame 45, and the impurities in the oil can be filtered through the setting of the rectangular filter frame 45, and then through the setting of the filter hole 47, the oil outlet 44 and the oil inlet channel 33, the filtered oil is conveniently discharged into the interior of the oil pump body 3, and through the cooperation of the motor 2, the driving gear 31 and the driven gear 32, the oil is convenient to be transported, so that the oil can be discharged through the oil outlet channel 34.

[0023] Embodiment 2:

[0024] like Figure 1-5 As shown, a threaded sealing cover 48 is threadedly sleeved on the top of the filter cover 41, a sealing gasket 483 is fixedly connected to the bottom of the threaded sealing cover 48, an annular limiting groove 482 is provided at the bottom of the threaded sealing cover 48, limiting sliders 481 are fixedly connected to the two sides of the top of the rectangular filter frame 45, the outer wall of the limiting slider 481 is slidably connected to the inside of the annular limiting groove 482, an annular sealing groove 484 is provided on the top of the filter cover 41, and the outer wall of the sealing gasket 483 is arranged inside the annular sealing groove 484.

[0025] In this embodiment, the sealing performance between the threaded sealing cover 48 and the filter cover 41 can be increased by cooperating with the sealing gasket 483 and the annular sealing groove 484. For example, when the rectangular filter frame 45 is disassembled, the threaded sealing cover 48 is spirally rotated, and the annular limiting groove 482 at the bottom of the threaded sealing cover 48 moves on the outer wall of the limiting slider 481. By cooperating with the annular limiting groove 482 and the limiting slider 481, the threaded sealing cover 48 can keep the rectangular filter frame 45 in its original posture while rotating, so that the rectangular filter frame 45 will not rotate with the threaded sealing cover 48. When the threaded sealing cover 48 is separated from the top of the inner cavity of the filter cover 41, the threaded sealing cover 48 is moved upward again, and the threaded sealing cover 48 drives the rectangular filter frame 45 to be taken out from the inside of the filter cover 41 through the limiting slider 481. At this time, the staff can clean the oil impurities inside the rectangular filter frame 45 through the oil inlet groove 46.

[0026] In summary, if Figure 1-5As shown, this oil pump structure is connected to the external oil pipe through the pipe connector 42 when in use. The oil inside the oil pipe can be discharged into the rectangular filter frame 45 through the pipe connector 42, the oil inlet 43 and the oil inlet groove 46. After being filtered by the rectangular filter frame 45, it is discharged into the oil pump body 3 through multiple filter holes 47, the oil outlet 44 and the oil inlet channel 33. The output end of the motor 2 drives the driving gear 31 to rotate, and the driving gear 31 drives the driven gear 32 to rotate in the opposite direction, so that the oil can be transported and discharged through the oil outlet channel 34. When there are more oil impurities in the rectangular filter frame 45, the staff can spirally rotate the threaded sealing cover 48, and at the same time, the annular limiting slide groove 482 at the bottom of the threaded sealing cover 48 moves on the outer wall of the limiting slide block 481, so that the threaded sealing cover 48 is separated from the filter cover. 41 inner cavity, then move the threaded sealing cover 48 upwards, the threaded sealing cover 48 drives the rectangular filter frame 45 to move through the limit slider 481, and the rectangular filter frame 45 can be taken out from the inside of the filter cover 41. At this time, the staff can clean the oil impurities inside the rectangular filter frame 45 through the oil inlet groove 46. After cleaning, move the rectangular filter frame 45 to the inside of the filter cover 41, and make the oil inlet groove 46 located on one side of the oil inlet 43. At this time, rotate the threaded sealing cover 48 in the opposite direction, and thread the threaded sealing cover 48 to the top of the inner cavity of the filter cover 41 in the same way. While moving, the threaded sealing cover 48 drives the sealing gasket 483 to move to the inside of the annular sealing groove 484, and utilizes the cooperation of the sealing gasket 483 and the annular sealing groove 484 to increase the sealing between the threaded sealing cover 48 and the filter cover 41.
