Axial piston pump is a common type of hydraulic pump. Due to its small size, light weight, and high efficiency, it is widely used in construction machinery, metallurgical equipment, aerospace and other fields. However, due to the complexity of the internal components of the axial piston pump, it is susceptible to damage and failure due to the influence of material particles and other factors. The following are the diagnostic and troubleshooting methods for internal component damage of axial piston pumps: 1. Bad noise: When the axial piston pump has abnormal noise during operation, it may be caused by damage to the internal components of the pump such as bearings, gears, bearing housings, etc. At this point, the pump needs to be disassembled and its components inspected. If some parts are found to be worn or deformed, the corresponding parts need to be replaced in time. 2. Leakage: When the axial piston pump leaks, it may be due to the failure of seals such as O-rings, seal rings, etc. In this case, it is necessary to check whether the seals inside the pump are intact, and replace worn or aged seals in time. 3. Vibration during operation: When the axial piston pump has abnormal vibration during operation, it may be caused by the imbalance of the internal components of the pump. At this time, it is necessary to check whether the rotor of the pump is out of balance and whether there is any deviation between the rotor and the supporting structure, and repair or replace it according to the situation. 4. Small or no flow output: If the output flow of the axial piston pump is reduced or completely stopped, it may be due to damage to the suction valve and overflow valve inside the oil pump, or it may be due to failure of the bearing or damage to the rotor. . In this case, the corresponding parts need to be inspected and replaced. 90L130-KN-5-BC-80-R-3-F1-H-00-GBA-32-32-24 90L130KN5BC80R3F1H00GBA323224 90-L-130-KN-5-BC-80-R-3-F1-H-00-GBA-32-32-24 90L130KN5BC80R3F1H00GBA323224 90L130-KN-5-BC-80-R-4-F1-F-03-GBA-14-14-24 90L130KN5BC80R4F1F03GBA141424 90-L-130-KN-5-BC-80-R-4-F1-F-03-GBA-14-14-24 90L130KN5BC80R4F1F03GBA141424 90L130-KN-5-BC-80-R-4-F1-F-03-GBA-42-14-24 90L130KN5BC80R4F1F03GBA421424 90-L-130-KN-5-BC-80-R-4-F1-F-03-GBA-42-14-24 90L130KN5BC80R4F1F03GBA421424 90L130-KN-5-CD-80-D-4-F1-L-03-GBA-35-35-24 90L130KN5CD80D4F1L03GBA353524 90-L-130-KN-5-CD-80-D-4-F1-L-03-GBA-35-35-24 90L130KN5CD80D4F1L03GBA353524 90L130-KN-5-CD-80-D-4-F1-L-03-GBA-35-35-28 90L130KN5CD80D4F1L03GBA353528 90-L-130-KN-5-CD-80-D-4-F1-L-03-GBA-35-35-28 90L130KN5CD80D4F1L03GBA353528 5. Temperature rise: When the axial piston pump finds that the temperature rises when it is working, it may be caused by poor circulation of the internal hydraulic oil or failure of the cooling system. At this time, it is necessary to check whether the flow rate of the hydraulic oil is normal and whether the cooling system is normal, and repair or replace the hydraulic oil and hydraulic oil filter in time. 6. Increased operating force: When the axial piston pump is working, it is found that the operating force increases, which may be due to damage to the piston or bearing inside the pump and the decrease in sealing performance. At this time, it is necessary to disassemble and check the corresponding parts, and replace or repair them according to the situation. 7. The pressure drop of the pump: When the output pressure of the axial piston pump drops, it may be due to the damage or poor sealing of the suction valve and overflow valve parts inside the pump. In this case, these parts need to be inspected or replaced directly. 8. Oil leakage: Oil leakage occurs when the axial piston pump is working, which may be caused by wear, aging or improper installation of the seals. At this time, it is necessary to check all the seals of the pump, and replace the worn or aged seals in time to ensure the normal sealing performance. 9. The noise of the pump is high: when the axial piston pump makes abnormally loud noises when it is working, it may be caused by damage to the internal components of the pump such as gears and bearings. At this time, it is necessary to disassemble and repair, repair or replace damaged parts to ensure the normal operation of the equipment. 10. Odor: When the axial piston pump has an odor when it is working, it may be caused by hydraulic oil pollution, or it may be that impurities such as metal filings generated by the wear of the internal components of the pump enter the hydraulic system. At this time, it is necessary to check the quality of the hydraulic oil. If any problem is found, the hydraulic oil and hydraulic oil filter should be replaced in time, and the impurities inside the hydraulic system should be cleaned. 11. Vibration: Abnormal vibration occurs when the axial piston pump is working, which may be caused by poor assembly, worn internal components or damaged bearings. At this time, it is necessary to disassemble and overhaul the pump, find out the problem, and replace the damaged parts according to the situation. 12. Reduced speed: When the axial piston pump is working, the speed is reduced, which may be caused by the failure of the motor or drive system. At this time, it is necessary to check the motor and drive system, find out the cause of the failure, and carry out corresponding maintenance. 13. Large pump resistance: When the axial piston pump has high resistance when it is working, it may be due to the blockage of the suction port or the high viscosity of the hydraulic oil. At this time, it is necessary to check whether the suction port is blocked, and check whether the viscosity of the hydraulic oil meets the specified requirements. If there is a problem, it should be dealt with in time. 90L130-KN-5-CD-80-R-3-F1-F-03-GBA-42-42-24 90L130KN5CD80R3F1F03GBA424224 90-L-130-KN-5-CD-80-R-3-F1-F-03-GBA-42-42-24 90L130KN5CD80R3F1F03GBA424224 90L130-KN-5-CD-80-R-3-F1-H-03-GBA-35-35-24 90L130KN5CD80R3F1H03GBA353524 90-L-130-KN-5-CD-80-R-3-F1-H-03-GBA-35-35-24 90L130KN5CD80R3F1H03GBA353524 90L130-KN-5-CD-80-R-4-F1-F-03-GBA-35-35-24 90L130KN5CD80R4F1F03GBA353524 90-L-130-KN-5-CD-80-R-4-F1-F-03-GBA-35-35-24 90L130KN5CD80R4F1F03GBA353524 90L130-KN-5-CD-80-S-3-C8-H-03-GBA-32-32-24 90L130KN5CD80S3C8H03GBA323224 90-L-130-KN-5-CD-80-S-3-C8-H-03-GBA-32-32-24 90L130KN5CD80S3C8H03GBA323224 90L130-KN-5-CD-80-S-3-C8-H-03-GBA-35-35-26 90L130KN5CD80S3C8H03GBA353526 90-L-130-KN-5-CD-80-S-3-C8-H-03-GBA-35-35-26 90L130KN5CD80S3C8H03GBA353526 14. The temperature of the pump is too high: When the temperature of the axial piston pump is too high when it is working, it may be caused by poor lubrication, poor sealing or excessive heat generated by internal friction. At this time, it is necessary to check the quality and lubrication of the hydraulic oil, and check the status of each seal inside the pump. If a problem is found, it is necessary to replace the hydraulic oil and hydraulic oil filter in time, and check and replace the damaged seal. 15. The outlet pressure of the pump is unstable: when the axial piston pump is working, the outlet pressure is unstable, which may be caused by air or impurities in the hydraulic system, valve damage or improper adjustment, and internal component wear and other reasons. . At this time, it is necessary to check the hydraulic system to find out the cause of the unstable pressure, and carry out corresponding maintenance according to the situation. 16. The pump cannot start normally: When the axial piston pump cannot start normally, it may be due to power failure, motor damage, poor wiring or fuse blown and other reasons. At this time, it is necessary to check the power supply and circuit to determine whether there is a fault, and to repair or replace it accordingly. In short, for the diagnosis and elimination of the internal component damage of the axial piston pump, it is necessary to comprehensively consider various factors, and select corresponding methods and measures for maintenance and maintenance according to the specific situation. At the same time, daily maintenance and maintenance work is also very important. It is necessary to clean and check the equipment in time to ensure its normal operation and avoid failures.
