The hydraulic pump for dock loading and unloading machinery is an important equipment, which is widely used in various fields such as port cargo handling, excavating machines, compressors, and oil field drilling rigs. To ensure the proper functioning of your hydraulic pump, here are some maintenance recommendations: 1. Regular replacement of hydraulic oil: In order to avoid oil aging, oxidation, pollution and other problems, the hydraulic oil used in hydraulic pumps needs to be replaced regularly. It is recommended to formulate a reasonable replacement cycle according to the production situation, and operate according to the specification requirements. 2. Pay attention to the maintenance of seals: seals are one of the most important components of hydraulic pumps, and they play a very important role in sealing the pump body. The condition of the seals should be checked frequently and maintained and replaced in time. 3. Prevent overload: In the process of using the hydraulic pump, it is necessary to pay attention to the matching of output power and input power to prevent excessive load from causing damage to the pump. It is recommended to install an overload protection device. When the pump is impacted by overload, it will stop in time to prevent failure. 4. Stable installation: The installation of the hydraulic pump should be stable and reliable to avoid problems such as vibration and looseness. The pipeline of the hydraulic pump also needs to be kept unblocked to ensure smooth flow of fluid. 5. Regular inspection: In order to find problems and repair them in time, it is necessary to inspect all parts of the hydraulic pump at regular intervals, and carry out necessary maintenance and maintenance treatments. 90R130-KA-5-CD-80-L-4-C8-H-00-GBA-26-26-26 90R130KA5CD80L4C8H00GBA262626 90-R-130-KA-5-CD-80-L-4-C8-F-05-GBA-29-29-24 90R130KA5CD80L4C8F05GBA292924 90R130-KA-5-CD-80-L-4-C8-F-05-GBA-29-29-24 90R130KA5CD80L4C8F05GBA292924 90-R-130-KA-5-CD-80-L-4-C8-F-05-GBA-26-26-24 90R130KA5CD80L4C8F05GBA262624 90R130-KA-5-CD-80-L-4-C8-F-05-GBA-26-26-24 90R130KA5CD80L4C8F05GBA262624 90-R-130-KA-5-CD-80-L-4-C8-F-03-GBA-35-35-24 90R130KA5CD80L4C8F03GBA353524 90-R-130-KA-5-CD-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5CD80L3C8H03GBA424224 90-R-130-KA-5-CD-80-L-3-C8-H-03-GBA-32-32-24 90R130KA5CD80L3C8H03GBA323224 90R130-KA-5-CD-80-L-3-C8-H-03-GBA-32-32-24 90R130KA5CD80L3C8H03GBA323224 90-R-130-KA-5-CD-80-L-3-C8-F-03-GBA-42-42-28 90R130KA5CD80L3C8F03GBA424228 6. Reasonable use: Reasonable use of hydraulic pumps is also the key to ensuring their normal operation. Operate in accordance with the instructions provided by the manufacturer, master various parameters and performance indicators, and abide by relevant safety regulations. 7. Pay attention to the removal of gas in the pump: During the use of the hydraulic pump, air may enter the pump body, resulting in gas accumulation and unstable pressure. Therefore, it is necessary to pay attention to the removal of gas in the pump to keep the hydraulic system in a stable state. 8. Prevent overheating: When the hydraulic pump is working, due to the existence of energy conversion, a large amount of heat energy will be generated, resulting in a rise in temperature. If it is used for a long time, it may overheat. Heat dissipation conditions should be considered during installation, such as adding radiators and protective covers, to avoid overheating and damage to equipment. 9. Maintenance professionalism: hydraulic pump is a kind of complex mechanical equipment, which requires professional and technical personnel to maintain and repair. Parts cannot be replaced or repaired at will, and necessary inspections and tests should be carried out in accordance with professional maintenance specifications and operating procedures. 10. Pay attention to cleaning and maintenance: the hydraulic pump will inevitably be eroded by dust, water, particles and other pollutants during operation, so it needs to be cleaned and maintained regularly. Special cleaning agents and maintenance fluids can be used for cleaning and maintenance to keep the pump body clean, smooth and corrosion-resistant. 11. Regularly replace the filter element: The filter element is used to filter pollutants in the hydraulic system. If it is not replaced for a long time, it may cause excessive impurities to accumulate inside the hydraulic pump and affect its normal operation. Therefore, the filter element needs to be checked and replaced regularly. 12. Adjustment and calibration: After the hydraulic pump is used for a period of time, some performance changes may occur, such as output pressure, flow and other parameters are unstable. If a problem is found, it should be adjusted and calibrated in time to ensure that the performance index of the hydraulic pump is normal. 13. Pressure test: Every year or at regular intervals, a hydraulic pump pressure test is required to check whether its output pressure and flow meet the specification requirements. The test results can be used as a reference for future maintenance and adjustments. 14. Clean the hydraulic pipeline: During the use of the hydraulic pump, the hydraulic pipeline will grow with time and gradually accumulate dirt and impurities, which will affect the stability of the hydraulic system. Therefore, it is necessary to clean the hydraulic pipeline regularly to ensure that the hydraulic system is unimpeded. 15. Protect the interface and electrical equipment: The interface and electrical equipment of the hydraulic pump also need to be protected. The interface should be checked regularly to ensure good connection; electrical equipment such as controllers, switches, etc. should pay attention to moisture-proof, short-circuit proof and other issues, and carry out regular inspection and maintenance. 16. Hydraulic pump installation location: When selecting the hydraulic pump installation location, the surrounding environmental factors should be considered to avoid interference from rain, sunlight or other external factors. At the same time, it is also necessary to consider whether the installation location is convenient for maintenance and inspection. 90R130-KA-5-CD-80-L-3-C8-F-03-GBA-42-42-28 90R130KA5CD80L3C8F03GBA424228 90-R-130-KA-5-CD-80-L-3-C8-F-03-GBA-42-42-24 90R130KA5CD80L3C8F03GBA424224 90R130-KA-5-CD-80-L-3-C8-F-03-GBA-42-42-24 90R130KA5CD80L3C8F03GBA424224 90-R-130-KA-5-CD-80-L-3-C8-F-03-GBA-35-35-24 90R130KA5CD80L3C8F03GBA353524 90R130-KA-5-CD-80-L-3-C8-F-03-GBA-35-35-24 90R130KA5CD80L3C8F03GBA353524 90-R-130-KA-5-CD-80-D-4-F1-L-05-GBA-35-35-24-F059 90R130KA5CD80D4F1L05GBA353524F059 90R130-KA-5-CD-80-D-4-F1-L-05-GBA-35-35-24-F059 90R130KA5CD80D4F1L05GBA353524F059 90-R-130-KA-5-CD-80-D-4-F1-L-05-GBA-35-35-24 90R130KA5CD80D4F1L05GBA353524 90R130-KA-5-CD-80-D-4-F1-L-05-GBA-35-35-24 90R130KA5CD80D4F1L05GBA353524 90-R-130-KA-5-CD-80-D-4-F1-L-03-GBA-42-42-24 90R130KA5CD80D4F1L03GBA424224 17. Use standard accessories: In order to ensure the normal operation of the hydraulic pump, standard accessories and accessories should be used, and low-quality accessories that do not meet the standards should be avoided, which will have a negative impact on the performance and life of the hydraulic pump. 18. Regularly check the pressure gauge: The output pressure of the hydraulic pump is detected by the pressure gauge, so it is necessary to regularly check whether the pressure gauge is working normally, and if any problem is found, it should be replaced or adjusted in time. 19. Pay attention to the sealing performance: the sealing performance of the hydraulic pump is directly related to its working efficiency and life, so it is necessary to pay attention to the maintenance and replacement of the seals. Especially when it is restarted after a long period of non-use, it is necessary to pay attention to whether the sealing performance is normal. 20. Use hydraulic oil: The liquid medium of the hydraulic pump is hydraulic oil, and the appropriate hydraulic oil should be selected according to the use of the equipment, and the use of hydraulic oil that does not meet the standards should be avoided. The cleanliness and viscosity of the hydraulic oil also need to be checked regularly to avoid contamination and poor fluidity that lead to failure of the hydraulic pump. The above are the precautions for using and maintaining hydraulic pumps for dock loading and unloading machinery. The service life of the hydraulic pump can be extended to ensure the normal operation and production efficiency of the equipment, and can be extended through careful and professional maintenance.
