The abnormal sequence action of the plunger pump may be caused by the following aspects: 1. Displacement error: When the plunger pump is working, if the displacement is inconsistent, the residence time of the plunger on each working stroke will be different, which will affect the sequential action of the pump. At this time, the problem can be solved by adjusting the displacement of the plunger pump. 2. Oil leakage: The oil seal, sealing ring and other components inside the plunger pump are damaged, which will cause oil leakage, which will affect the normal operation of the pump. At this point the pump seals need to be inspected and replaced. 3. High stagnant pressure: In some cases, the stagnant pressure in the hydraulic system is too high, which will affect the sequential action of the plunger pump. At this time, the problem can be solved by reducing the system pressure (such as by reducing the load or increasing the pressure setting of the system pressure relief valve). 4. Other reasons: For example, the internal parts of the plunger pump are damaged, polluted, worn, etc., which may cause the plunger pump to operate abnormally in sequence. At this time, it is necessary to check the hydraulic pump in detail to find out the fault, and then repair or replace it. In view of the above reasons that may lead to the abnormal sequence action of the plunger pump, we should take corresponding measures to eliminate the fault. The specific method is as follows: 90R130-KA-5-CD-80-P-4-C8-F-03-GBA-35-35-24 90R130KA5CD80P4C8F03GBA353524 90-R-130-KA-5-CD-80-P-3-F1-H-03-GBA-42-42-24 90R130KA5CD80P3F1H03GBA424224 90R130-KA-5-CD-80-P-3-F1-H-03-GBA-42-42-24 90R130KA5CD80P3F1H03GBA424224 90-R-130-KA-5-CD-80-P-3-C8-H-03-GBA-42-42-24 90R130KA5CD80P3C8H03GBA424224 90R130-KA-5-CD-80-P-3-C8-H-03-GBA-42-42-24 90R130KA5CD80P3C8H03GBA424224 90-R-130-KA-5-CD-80-P-3-C8-H-03-GBA-35-35-24 90R130KA5CD80P3C8H03GBA353524 90R130-KA-5-CD-80-P-3-C8-H-03-GBA-35-35-24 90R130KA5CD80P3C8H03GBA353524 90-R-130-KA-5-CD-80-P-3-C8-H-03-GBA-30-30-24 90R130KA5CD80P3C8H03GBA303024 90R130-KA-5-CD-80-P-3-C8-H-03-GBA-30-30-24 90R130KA5CD80P3C8H03GBA303024 90-R-130-KA-5-CD-80-P-3-C8-F-04-GBA-32-32-24 90R130KA5CD80P3C8F04GBA323224 1. Check and adjust the displacement: Check whether the displacement of the hydraulic pump in the hydraulic system is consistent, if not, you need to adjust the displacement of the hydraulic pump to achieve consistency. 2. Replace the seals: Check whether the oil seals, seal rings and other components inside the hydraulic pump are damaged or worn. If you need to replace them, you can contact the hydraulic pump manufacturer for replacement. 3. Reduce stagnant pressure: In view of the problem of excessive stagnant pressure in the system, the stagnant pressure can be reduced by reducing the load and increasing the pressure setting of the system pressure relief valve. 4. Conduct a detailed inspection: If the above measures cannot effectively solve the problem, a detailed inspection is required to determine the specific cause of the failure inside the hydraulic pump, and then repair or replace it. 5. Clean the hydraulic system: When there are a lot of pollutants in the hydraulic system, it will affect the normal operation of the hydraulic pump. At this time, the method of cleaning the hydraulic system can be used to troubleshoot. 6. Check whether the ball valve is stuck or damaged: the ball valve is a key component of the plunger pump sequence action, if the ball valve is stuck or damaged, it will also cause the pump sequence action to be abnormal. At this time, it is necessary to check whether the ball valve is normal, and replace the damaged ball valve. 7. Adjust the control electromagnet: The control electromagnet is an important part of the hydraulic pump control system. If the control electromagnet is not adjusted properly, it will also cause the plunger pump to operate abnormally. At this time, the control solenoid needs to be adjusted to ensure its normal operation. 8. Check the oil circuit connection: check the oil circuit connection of the hydraulic system at all times to ensure that each connection is well sealed. 9. Check the quality of hydraulic oil: The quality of hydraulic oil in the hydraulic system directly affects the normal operation of the plunger pump. If the hydraulic oil is polluted or too old, the plunger pump will not work properly. At this time, new hydraulic oil can be replaced or cleaned. 90R130-KA-5-CD-80-P-3-C8-F-04-GBA-32-32-24 90R130KA5CD80P3C8F04GBA323224 90-R-130-KA-5-CD-80-L-4-F1-F-05-GBA-35-35-24 90R130KA5CD80L4F1F05GBA353524 90R130-KA-5-CD-80-L-4-F1-F-05-GBA-35-35-24 90R130KA5CD80L4F1F05GBA353524 90-R-130-KA-5-CD-80-L-4-F1-F-03-GBA-14-14-24 90R130KA5CD80L4F1F03GBA141424 90R130-KA-5-CD-80-L-4-F1-F-03-GBA-14-14-24 90R130KA5CD80L4F1F03GBA141424 90-R-130-KA-5-CD-80-L-4-F1-F-00-GBA-14-14-24 90R130KA5CD80L4F1F00GBA141424 90R130-KA-5-CD-80-L-4-F1-F-00-GBA-14-14-24 90R130KA5CD80L4F1F00GBA141424 90-R-130-KA-5-CD-80-L-4-C8-H-03-GBA-42-42-24 90R130KA5CD80L4C8H03GBA424224 90R130-KA-5-CD-80-L-4-C8-H-03-GBA-42-42-24 90R130KA5CD80L4C8H03GBA424224 90-R-130-KA-5-CD-80-L-4-C8-H-00-GBA-26-26-26 90R130KA5CD80L4C8H00GBA262626 10. Check whether the oil return path is smooth: the smoothness of the oil return path is also a prerequisite for the normal operation of the plunger pump. If the oil return path is blocked, the sequence of the plunger pump will not operate normally. At this time, it is necessary to check whether the oil return circuit is unblocked, and carry out maintenance in time. 11. Check the wear of the pump body and plunger: During the long-term operation of the plunger pump, the pump body and plunger will wear out, which will lead to abnormal sequence action of the plunger pump. At this time, it is necessary to check the wear of the pump body and plunger and replace it in time. 12. Adjust the speed regulating screw of the pump: the speed regulating screw of the plunger pump is an important part to adjust the flow and pressure of the pump. If the speed regulating screw is loose or damaged, it will cause the plunger pump to act abnormally in sequence. At this time, the adjustment screw needs to be adjusted or replaced. In short, it needs rich experience and professional knowledge to troubleshoot the abnormal sequence action of the plunger pump. If you are not sure how to troubleshoot, it is best to find professional hydraulic maintenance personnel to check and deal with it. It is recommended to strengthen the maintenance of the hydraulic system in daily use, replace the hydraulic oil in time, and check the hydraulic components to reduce the possibility of failure.
