Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, in particular to a hydraulic pump with a filtering function. Background Art

[0002] It is the power element of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure. Their function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid and provide power to the hydraulic system.

[0003] After searching, the existing patent (Announcement No.: CN 203023176 U) discloses a hydraulic pump protection device and a hydraulic pump. The hydraulic pump protection device includes a bypass oil pipe and a pressure limiting valve arranged on the bypass oil pipe.

[0028] In this embodiment, mounting holes 6 are provided on the side of the oil outlet 5 and the back of the oil inlet 9, and the mounting holes 6 are set in the middle of the span. Because mounting holes 6 are provided on the side of the oil outlet 5 and the back of the oil inlet 9, the connecting pipe can be connected to the oil outlet 5 and the oil inlet 9 respectively through the mounting holes 6, and the mounting holes 6 are set in the middle of the span, which can prevent oil from leaking and dripping onto the surface of the connecting part.

[0029] In this embodiment, the regulating valve 7 passes through the top of the pump body 4 and is rotatably connected to the pump body 4. The diameter of the regulating plate 8 is consistent with the inner diameter of the oil outlet 5. By setting the regulating valve 7 and the regulating plate 8, the staff can drive the regulating plate 8 to rotate by rotating the regulating valve 7. When the regulating plate 8 rotates to block the oil outlet 5, the oil delivery can be stopped.

[0030] In this embodiment, a groove matching the filter plate 10 is opened on the back of the oil inlet 9, and the filter plate 10 is embedded in the groove on the back of the oil inlet 9. The filter plate 10 is embedded in the groove on the back of the oil inlet 9 so that the fixed groove on the back of the filter plate 10 coincides with the fixed groove on the back of the groove of the oil inlet 9.

[0031] In this embodiment, the back of the filter plate 10 and the back of the groove of the oil inlet 9 are both provided with fixing grooves matching the screws 11, and the screws 11 are embedded in the fixing grooves on the back of the filter plate 10 and the groove of the oil inlet 9. When the fixing groove on the back of the filter plate 10 coincides with the fixing groove on the back of the groove of the oil inlet 9, the screws 11 are tightened in the fixing grooves on the back of the filter plate 10 and the back of the groove of the oil inlet 9, and the filter plate 10 can be fixed inside the oil inlet 9. At this time, the connecting pipes are respectively connected to the oil inlet 9 and the oil outlet 5 through the mounting holes 6. When the oil flows from the connecting pipe into the oil inlet 9, the filter plate 10 will block the debris inside the oil, thereby achieving the purpose of filtering the oil and preventing the debris in the oil from causing damage to the internal parts of the hydraulic pump, thereby improving the working efficiency of the hydraulic pump. Example 2

[0032] On the basis of Example 1, a preferred embodiment of a hydraulic pump with a filtering function provided by the utility model is as follows: Figures 1 to 6 As shown: a shock-absorbing base 12 is attached to the bottom of the base plate 1, and a shock-absorbing damper 13 is fixedly connected inside the shock-absorbing base 12.

[0033] In this embodiment, four groups of shock-absorbing bases 12 are provided, and four groups of rectangular grooves matching the shock-absorbing bases 12 are opened at the bottom of the base plate 1. By setting four groups of shock-absorbing bases 12, because four groups of grooves matching the shock-absorbing bases 12 are opened at the bottom of the base plate 1, the base plate 1 can be placed on the top of the four groups of bases 12 through its four groups of grooves, so that the four groups of shock-absorbing bases 12 are respectively embedded in the four groups of grooves at the bottom of the base plate 1.

[0034] In this embodiment, four groups of shock-absorbing dampers 13 are fixedly connected inside each group of shock-absorbing bases 12.

[0035] The working principle and use process of the utility model are as follows: first, four groups of shock-absorbing bases 12 are arranged. Since four groups of grooves matching the shock-absorbing bases 12 are provided at the bottom of the bottom plate 1, the bottom plate 1 can be placed on the top of the four groups of bases 12 through its four groups of grooves, so that the four groups of shock-absorbing bases 12 are respectively embedded in the four groups of grooves at the bottom of the bottom plate 1. Since the shock-absorbing base is provided with a shock-absorbing damper 13 inside, it can play a certain buffering role on the shaking of the motor body 2, thereby achieving the purpose of shock absorption. Then, the motor body 2 is placed on the top of the bottom plate 1 and installed on the top of the bottom plate 1 through the movable bolts 3. Then, the filter plate 10 is embedded in The inside of the groove on the back of the oil port 9 makes the fixing groove on the back of the filter plate 10 coincide with the fixing groove on the back of the groove of the oil inlet 9, and then tighten the screws 11 into the fixing grooves on the back of the filter plate 10 and the back of the groove of the oil inlet 9, so that the filter plate 10 can be fixed inside the oil inlet 9. At this time, the connecting pipe is connected to the oil inlet 9 and the oil outlet 5 respectively through the mounting hole 6. When the oil flows into the oil inlet 9 from the connecting pipe, the filter plate 10 will block the debris inside the oil, so as to achieve the purpose of filtering the oil and prevent the debris in the oil from causing damage to the internal parts of the hydraulic pump, thereby improving the working efficiency of the hydraulic pump. Finally, the motor main body 2 is started to drive the pump body 4 to work.
