The leakage problem of hydraulic pump rotor and blade end surface is mainly manifested as oil leakage from the pump rotor and blade end surface, which will lead to a decrease in pump efficiency, increase energy consumption, and even cause pump failure. The reasons for the leakage of hydraulic pump rotor and blade end face may be as follows: Deformation: Due to the high hydraulic pressure when the hydraulic pump is working, it is easy to cause the deformation of the pump body, which will cause the end surface clearance between the pump rotor and the blade to become larger, resulting in leakage. Wear: Long-term use will cause the end faces of the pump rotors and blades to wear, resulting in leakage. Contamination: Contaminants in hydraulic pumps can clog the small gaps between the pump rotor and the vanes, causing oil loss and concentrating pressure on the end faces, causing leaks. To address these issues, the following measures can be taken: Select suitable materials: select hard and wear-resistant materials, such as cemented carbide, to make rotors and blades. Good lubrication: inject enough lubricating oil into the pump body to maintain the cleanliness and adequacy of the lubricating oil, and reduce the wear of the pump rotor and blades. Strengthen maintenance: maintain and clean the hydraulic pump regularly to prevent the accumulation of pollutants, and replace severely worn parts in time. 90R130-KN-5-BC-80-L-3-F1-F-03-GBA-35-35-24 90R130KN5BC80L3F1F03GBA353524 90-R-130-KN-5-AB-80-S-4-F1-H-02-GBA-42-42-24 90R130KN5AB80S4F1H02GBA424224 90R130-KN-5-AB-80-S-4-F1-H-02-GBA-42-42-24 90R130KN5AB80S4F1H02GBA424224 90-R-130-KN-5-AB-80-R-3-F1-H-03-GBA-29-29-24 90R130KN5AB80R3F1H03GBA292924 90R130-KN-5-AB-80-R-3-F1-H-03-GBA-29-29-24 90R130KN5AB80R3F1H03GBA292924 90-R-130-KN-5-AB-80-P-3-C8-H-03-GBA-42-42-20 90R130KN5AB80P3C8H03GBA424220 90R130-KN-5-AB-80-P-3-C8-H-03-GBA-42-42-20 90R130KN5AB80P3C8H03GBA424220 90-R-130-KN-5-AB-80-L-4-F1-F-03-GBA-42-42-24 90R130KN5AB80L4F1F03GBA424224 90R130-KN-5-AB-80-L-4-F1-F-03-GBA-42-42-24 90R130KN5AB80L4F1F03GBA424224 90-R-130-KN-2-NN-80-S-3-F1-F-03-GBA-35-35-24 90R130KN2NN80S3F1F03GBA353524 Control the working pressure: Try to control the working pressure of the hydraulic pump during work to avoid excessive pressure from bringing unnecessary load on the pump rotor and blade end faces. Optimum design: When designing parts such as the pump body and the pump rotor, the end face clearance shall be minimized to reduce the internal leakage of the pump, and at the same time, the strength and rigidity of the pump body shall be strengthened to prevent the deformation of the pump body. Strengthen inspection: Regularly inspect and test the hydraulic pump to avoid problems such as wear, deformation and corrosion of the pump main shaft, impeller and other components, ensure the stability and reliability of the hydraulic pump, and improve the efficiency and life of the pump. To sum up, the leakage problem of hydraulic pump rotor and blade end surface needs to be dealt with from various aspects and corresponding measures can be taken to effectively reduce the internal leakage of the pump, improve the efficiency and reliability of the pump, and prolong the service life of the pump. In addition, for the leakage of hydraulic pump rotors and blade end faces, some emergency measures can be taken to avoid more serious failures: Stop in time: Once the leakage of the hydraulic pump rotor and blade end face is found, it should be stopped immediately for inspection to avoid further deterioration. Replacement of seals: If the inspection finds that the leakage of the pump rotor and the end face of the blade is caused by the aging and damage of the seals, the corresponding seals should be replaced in time to ensure the normal operation of the pump. Install an anti-leakage device: install an anti-leakage device at the end face gap of the hydraulic pump, such as an O-ring, etc., to increase the sealing performance of the end face gap and reduce the leakage, thereby prolonging the service life of the pump. In short, in daily use, it is necessary to pay attention to the maintenance and maintenance of the hydraulic pump, and carry out regular inspection and repairs to avoid problems such as leakage of the hydraulic pump rotor and blade end faces. At the same time, if there is a leakage problem, take emergency measures in time to avoid more serious failures and impacts. In addition, if the leakage of the hydraulic pump rotor and blade end surface is found, the leakage can also be reduced by adjusting the working mode of the pump: Reduce the load: If the hydraulic pump works under the condition of excessive load, it is easy to cause the gap between the pump rotor and the end face of the blade to become larger, resulting in leakage. Therefore, the load can be appropriately reduced, and the working pressure and load of the pump can be reduced. Reduce the speed: If the speed of the hydraulic pump is too fast, it is easy to cause the gap between the pump rotor and the end face of the blade to increase, and increase the leakage. Therefore, the speed of the hydraulic pump can be appropriately reduced, and the friction force of the pump rotor and blades can be reduced, thereby reducing the leakage. 90R130-KN-2-NN-80-S-3-F1-F-03-GBA-35-35-24 90R130KN2NN80S3F1F03GBA353524 90-R-130-KN-1-NN-80-S-4-F1-F-03-GBA-35-35-24 90R130KN1NN80S4F1F03GBA353524 90R130-KN-1-NN-80-S-4-F1-F-03-GBA-35-35-24 90R130KN1NN80S4F1F03GBA353524 90-R-130-KN-1-NN-80-L-4-F1-H-00-GBA-29-29-24 90R130KN1NN80L4F1H00GBA292924 90R130-KN-1-NN-80-L-4-F1-H-00-GBA-29-29-24 90R130KN1NN80L4F1H00GBA292924 90-R-130-KN-1-NN-80-L-4-F1-F-03-GBA-36-36-20 90R130KN1NN80L4F1F03GBA363620 90R130-KN-1-NN-80-L-4-F1-F-03-GBA-36-36-20 90R130KN1NN80L4F1F03GBA363620 90-R-130-KN-1-NN-80-L-4-C8-H-03-GBA-32-32-24-F001 90R130KN1NN80L4C8H03GBA323224F001 90R130-KN-1-NN-80-L-4-C8-H-03-GBA-32-32-24-F001 90R130KN1NN80L4C8H03GBA323224F001 90-R-130-KN-1-CD-80-S-4-F1-H-03-GBA-35-35-24 90R130KN1CD80S4F1H03GBA353524 Adjust the inlet and outlet connections of the pump: If the inlet and outlet connections of the hydraulic pump are inappropriate, it will easily cause the gap between the rotor and blade end faces of the hydraulic pump to become larger and cause leakage. Therefore, it can be considered to adjust the connection mode of the inlet and outlet to make the connection tighter and reduce the leakage. In short, the leakage problem of hydraulic pump rotor and blade end surface is a comprehensive problem, and it is necessary to start from many aspects and take corresponding measures to reduce leakage and improve the efficiency and reliability of hydraulic pump. The most important thing is to keep the hydraulic pump in good condition, maintain and repair it in time, and prevent the occurrence of problems such as leakage of the hydraulic pump rotor and blade end face. In addition, some operational details need to be paid attention to to avoid the leakage of hydraulic pump rotor and blade end face: Avoid overload: When using hydraulic pumps, avoid overloading and try to make the hydraulic pump work within the standard load range. Overload is easy to aggravate the wear of hydraulic pump rotor and blade end face, thus causing leakage. Avoid reverse operation: The direction of rotation of the hydraulic pump is regulated, if reverse operation occurs, it will not only affect the efficiency of the pump, but also cause leakage problems. Maintain the quality of hydraulic oil: select high-quality hydraulic oil, and regularly replace and check the oil quality to avoid oil pollution or aging affecting the normal operation of the hydraulic pump, and at the same time reduce friction and wear on the rotor and blade end faces of the hydraulic pump, reduce Leakage. In short, in daily use, it is necessary to pay attention to the operation details of the hydraulic pump, keep the hydraulic system clean and in good condition, and strengthen the maintenance and maintenance of the hydraulic pump to prevent the occurrence of problems such as leakage of the rotor and blade end faces of the hydraulic pump.
