Hydraulic punching of hydraulic pumps usually occurs for the following reasons: 1. Improper oil pipe layout. Bending, shortages, or improper placement of the tubing can cause hydraulic punching of the hydraulic pump. 2. The slide valve is not moving smoothly. Hydraulic ramming can also occur if the slide valve of the hydraulic pump is not moving smoothly. 3. The internal parts of the hydraulic pump are worn. If the components inside the hydraulic pump are severely worn, it may cause the hydraulic pump to hydraulically ram. 4. The inlet flow of the hydraulic pump is too large. If the inlet flow of the hydraulic pump is too large, it may also cause hydraulic ramming. The solution is as follows: 1. Adjust the layout of the oil pipe to ensure that the oil pipe is straight and not bent, and install it according to the correct arrangement. 2. Maintain and maintain the hydraulic pump, check whether the slide valve moves smoothly, and replace severely worn parts. 3. Install auxiliary components such as throttle valves to control the inlet flow of the hydraulic pump. 90-L-130-KA-5-NN-80-R-3-C8-H-03-GBA-30-30-24 90L130KA5NN80R3C8H03GBA303024 90L130-KA-5-NN-80-R-3-F1-F-03-GBA-42-42-24 90L130KA5NN80R3F1F03GBA424224 90-L-130-KA-5-NN-80-R-3-F1-F-03-GBA-42-42-24 90L130KA5NN80R3F1F03GBA424224 90L130-KA-5-NN-80-R-3-F1-H-03-EBA-42-42-24 90L130KA5NN80R3F1H03EBA424224 90-L-130-KA-5-NN-80-R-3-F1-H-03-EBA-42-42-24 90L130KA5NN80R3F1H03EBA424224 90L130-KA-5-NN-80-R-3-F1-H-03-GBA-14-14-20 90L130KA5NN80R3F1H03GBA141420 90-L-130-KA-5-NN-80-R-3-F1-H-03-GBA-14-14-20 90L130KA5NN80R3F1H03GBA141420 90L130-KA-5-NN-80-R-3-F1-H-03-GBA-35-35-24 90L130KA5NN80R3F1H03GBA353524 90-L-130-KA-5-NN-80-R-3-F1-H-03-GBA-35-35-24 90L130KA5NN80R3F1H03GBA353524 90L130-KA-5-NN-80-R-3-F1-H-03-GBA-42-42-24 90L130KA5NN80R3F1H03GBA424224 4. Add low-noise, high-efficiency oil to the hydraulic system, and maintain sufficient oil pressure to run smoothly, avoiding sharp flow changes during operation. 5. Make sure that the hydraulic system is installed correctly, check whether the quick connectors, threads and other connecting parts are firm and reliable, and avoid hydraulic shock caused by the loosening of the system. 6. Add an oil pump anti-shock buffer to the hydraulic system to make the oil pump run more stably. 7. Use a large enough oil tank to relieve oil pressure shock. 8. Increase the throttling device and damping device to slow down the change of flow rate and pressure, thereby reducing the possibility of hydraulic shock. 9. Select appropriate hydraulic valves, such as pressure reducing valves, sequence valves, overflow valves, etc., to maintain the smooth operation of the hydraulic system. 10. Observe the correct operating procedures, avoid operations such as rushing or emergency stop, and keep the flow and pressure in a stable state during the work process. 11. Minimize the air and impurities in the hydraulic system to ensure that the hydraulic oil is of good quality. 12. Observe the working parameters of the hydraulic system and avoid overload operation. 13. For the aging hydraulic system, parts should be replaced in time to ensure the normal operation of the system. 14. Before operating the hydraulic system, operations such as filling and exhausting should be performed first to ensure that the hydraulic oil and gas in the system are fully removed to avoid shocks caused by liquid compression. 15. Regularly check and replace the seals in the system to prevent failures caused by leakage. 16. Operate in strict accordance with the operating procedures of hydraulic equipment, and do not change or ignore the safety operation requirements. 17. For newly installed hydraulic equipment, a comprehensive trial run and test should be carried out before official use to find and eliminate possible problems. 18. Regularly maintain and maintain hydraulic equipment, replace worn and aged parts and hydraulic oil, and check whether the connections in the system are firm and reliable. 19. During the operation of hydraulic equipment, strictly control the flow and pressure to avoid dangerous situations such as overload operation and rapid changes resulting in hydraulic shock. 20. For the failure and abnormal situation of hydraulic equipment, the operation should be stopped in time and the investigation should be carried out to avoid further expansion of losses and safety accidents. 21. When designing and manufacturing hydraulic equipment, devices such as shock absorption and buffering should be used as much as possible, and the type and viscosity of hydraulic oil should be reasonably selected to reduce pressure fluctuations in the system. 90-L-130-KA-5-NN-80-R-3-F1-H-03-GBA-42-42-24 90L130KA5NN80R3F1H03GBA424224 90L130-KA-5-NN-80-R-4-C8-F-03-GBA-26-26-24 90L130KA5NN80R4C8F03GBA262624 90-L-130-KA-5-NN-80-R-4-C8-F-03-GBA-26-26-24 90L130KA5NN80R4C8F03GBA262624 90L130-KA-5-NN-80-R-4-F1-F-03-GBA-38-38-24 90L130KA5NN80R4F1F03GBA383824 90-L-130-KA-5-NN-80-R-4-F1-F-03-GBA-38-38-24 90L130KA5NN80R4F1F03GBA383824 90L130-KA-5-NN-80-S-3-C8-F-03-GBA-32-32-24 90L130KA5NN80S3C8F03GBA323224 90-L-130-KA-5-NN-80-S-3-C8-F-03-GBA-32-32-24 90L130KA5NN80S3C8F03GBA323224 90L130-KA-5-NN-80-S-3-C8-F-03-GBA-35-35-24 90L130KA5NN80S3C8F03GBA353524 90-L-130-KA-5-NN-80-S-3-C8-F-03-GBA-35-35-24 90L130KA5NN80S3C8F03GBA353524 90L130-KA-5-NN-80-S-3-C8-F-03-GBA-38-38-30 90L130KA5NN80S3C8F03GBA383830 22. Use sequential control technology or flow and pressure regulators to control the pressure and flow in the hydraulic system to avoid dangerous situations such as hydraulic shock caused by sudden changes. 23. Install pressure sensors, flow sensors and other instruments inside the hydraulic equipment to monitor the operating status of the system in real time, find abnormalities in time and deal with them. 24. Enhance the safety awareness and skills of operators, and improve their awareness and resilience to dangerous situations such as hydraulic shocks. In short, in the process of using and maintaining hydraulic equipment, it is necessary to comprehensively consider multiple factors, design a reasonable hydraulic system, strictly abide by operating procedures and safety standards, and strengthen education and training to jointly reduce the risk of hydraulic shock. Ensure the safety of staff and the normal operation of equipment.
