Sealing and pressure resistance are important considerations for any hydraulic pump, including Danfoss piston pumps. Here are some common sealing and pressure resistance issues that can occur with these pumps: Seal failure: One of the most common problems with piston pumps is seal failure, which can lead to oil leakage and reduced pump performance. Seals in piston pumps are often exposed to high pressure and wear, and may need to be replaced periodically to ensure proper operation. Pressure drop: Another issue that can affect the performance of a piston pump is pressure drop, which can occur if there is a blockage or restriction in the hydraulic circuit. This causes pressure and flow to drop and can affect the overall operation of the hydraulic system. Cavitation: Cavitation is a phenomenon that occurs when the pressure in a hydraulic system drops below the vapor pressure of the hydraulic oil. This can cause air pockets to form that can damage the pump and other components in the system. Overpressure: Overpressure is another common problem that can occur with hydraulic pumps. If the pressure in the system exceeds the rated pressure of the pump, it can cause damage to the pump and other components in the system. To prevent these problems, it is important to ensure that the displacement pump is sized and installed for the application. Regular maintenance, including checking and replacing seals as needed, can also help prevent seal failure and other problems. It is also important to monitor the pressure and flow in the hydraulic system to ensure it is operating within the rated capacity of the pump. Additionally, selecting the correct type of seal and material for a plunger pump is important to ensure proper sealing and pressure resistance. Factors such as pumped fluid type, temperature, pressure and operating conditions should be considered when selecting the proper seal material. 90R130-MA-5-DE-80-L-4-C8-F-C5-GBA-29-29-24 90R130MA5DE80L4C8FC5GBA292924 90-R-130-MA-5-DE-80-L-3-F1-F-C5-GBA-26-26-24 90R130MA5DE80L3F1FC5GBA262624 90R130-MA-5-DE-80-L-3-F1-F-C5-GBA-26-26-24 90R130MA5DE80L3F1FC5GBA262624 90-R-130-MA-5-CD-80-S-4-F1-F-C5-GBA-42-42-24 90R130MA5CD80S4F1FC5GBA424224 90R130-MA-5-CD-80-S-4-F1-F-C5-GBA-42-42-24 90R130MA5CD80S4F1FC5GBA424224 90-R-130-MA-5-CD-80-S-3-C8-H-C5-GBA-42-42-24 90R130MA5CD80S3C8HC5GBA424224 90R130-MA-5-CD-80-S-3-C8-H-C5-GBA-42-42-24 90R130MA5CD80S3C8HC5GBA424224 90-R-130-MA-5-CD-80-S-3-C8-H-C5-GBA-26-26-24 90R130MA5CD80S3C8HC5GBA262624 90R130-MA-5-CD-80-S-3-C8-H-C5-GBA-26-26-24 90R130MA5CD80S3C8HC5GBA262624 90-R-130-MA-5-CD-80-S-3-C8-F-C5-GBA-35-35-24 90R130MA5CD80S3C8FC5GBA353524 Proper installation of the piston pump and its components, including the use of proper fittings and connections, can also help prevent leaks and pressure-related problems. Be sure to follow the manufacturer's installation guidelines, including torque specifications for bolts and fasteners, to ensure a secure, leak-free connection. Regular inspection and maintenance of hydraulic systems can help identify and resolve potential problems before they become more serious. This may include checking for leaks, monitoring pressure and flow, and replacing worn or damaged parts. Generally speaking, the correct selection, installation and maintenance of the plunger pump and its components are very important to ensure the stable and efficient operation of the hydraulic system. In addition to the above measures, it is also important to address any wear or damage to the piston pump components as soon as possible. Even small amounts of wear or damage can affect a pump's tightness and pressure resistance, resulting in leaks or reduced efficiency. Regular inspection of the condition of piston pump components such as plungers, cylinders, valve plates, and seals can help identify any signs of wear or damage. Replacing or repairing these components will help restore proper sealing and pressure resistance and prevent further damage to the hydraulic system. Another way to solve the problem of sealing and pressure resistance is to use a pressure relief valve. This valve helps regulate the pressure within the hydraulic system, preventing damage to the piston pump or other components due to excessive pressure. In summary, proper material selection, proper installation, regular inspection and maintenance, addressing wear and damage, and the use of pressure relief valves all help to ensure proper tightness and pressure resistance of Danfoss piston pumps. In addition, it is important to ensure that the displacement pump is operating within its specified range, both pressure and flow. Running the pump outside of the recommended ranges can cause increased component wear, which can lead to sealing and pressure-resistant problems. 90R130-MA-5-CD-80-S-3-C8-F-C5-GBA-35-35-24 90R130MA5CD80S3C8FC5GBA353524 90-R-130-MA-5-CD-80-R-4-F1-F-C5-GBA-35-35-24 90R130MA5CD80R4F1FC5GBA353524 90R130-MA-5-CD-80-R-4-F1-F-C5-GBA-35-35-24 90R130MA5CD80R4F1FC5GBA353524 90-R-130-MA-5-CD-80-R-3-C8-H-C5-GBA-45-45-28 90R130MA5CD80R3C8HC5GBA454528 90R130-MA-5-CD-80-R-3-C8-H-C5-GBA-45-45-28 90R130MA5CD80R3C8HC5GBA454528 90-R-130-MA-5-CD-80-R-3-C8-H-C5-GBA-35-35-30 90R130MA5CD80R3C8HC5GBA353530 90R130-MA-5-CD-80-R-3-C8-H-C5-GBA-35-35-30 90R130MA5CD80R3C8HC5GBA353530 90R130-MA-5-CD-80-L-4-F1-F-C5-GBA-32-32-24 90R130MA5CD80L4F1FC5GBA323224 90-R-130-MA-5-CD-80-L-4-C8-H-C5-GBA-35-35-28 90R130MA5CD80L4C8HC5GBA353528 90R130-MA-5-CD-80-L-4-C8-H-C5-GBA-35-35-28 90R130MA5CD80L4C8HC5GBA353528 Regularly monitoring hydraulic system pressure and flow, and making adjustments as needed, helps ensure that the displacement pump is operating within its recommended range and is not being subjected to excessive pressure or flow. Finally, it is also important to properly clean and maintain the hydraulic fluid in your system. Contaminants in the fluid can cause damage to pump components and impair the pump's tightness and pressure resistance. Regular hydraulic fluid changes, use of quality filters and ensuring hydraulic fluid is stored and handled properly can help prevent these problems. Overall, the proper operation, maintenance and monitoring of the piston pump and the entire hydraulic system are critical to ensuring proper sealing and pressure resistance and long-term reliable and efficient operation.
