There are several reasons why the hydraulic cylinder of a piston pump may slow down. Here are some of the most common reasons: Low hydraulic fluid level: A low hydraulic fluid level can cause hydraulic cylinders to slow down or stop working altogether. This could be due to a leak in the system or insufficient fluid in the reservoir. Regularly checking and maintaining hydraulic fluid levels is very important to ensure the system is properly lubricated and functioning properly. Contaminated Hydraulic Fluid: Contaminants such as dirt, debris or water in hydraulic fluid can cause hydraulic cylinders to slow down or malfunction. This can be prevented by using filters or screens in the system to remove contaminants before they reach the cylinders. Worn or damaged hydraulic seals: Over time, hydraulic seals in hydraulic cylinders can wear, causing leaks or loss of pressure. This can cause the cylinder to slow down or stop working altogether. Regular inspection and replacement of worn or damaged seals can help prevent this problem. Blocked Hydraulic Lines: If a hydraulic line is blocked or restricted, it can cause the cylinders to slow down or stop working. This can be caused by debris or foreign objects in the system or by kinked or bent wiring. Regular inspection and cleaning of hydraulic lines can help prevent this problem. Incorrect pressure setting: If the pressure in the hydraulic system is not set correctly, it will cause the cylinder to slow down or malfunction. This can be caused by improper installation or adjustment of the pressure relief valve or other components in the system. It is very important to install and adjust the hydraulic system according to the manufacturer's instructions. Mechanical wear: Over time, the mechanical parts of the cylinder, such as the piston or rod, can wear or become damaged, causing the cylinder to slow down or fail. Regular inspection and maintenance can help prevent this problem, but eventually the cylinder may need to be replaced. 90L100-KA-5-AB-80-S-4-C7-F-04-GBA-35-35-24 90L100KA5AB80S4C7F04GBA353524 90-L-100-KA-5-AB-80-S-4-C7-F-04-GBA-35-35-24 90L100KA5AB80S4C7F04GBA353524 90L100-KA-5-AB-80-S-4-S1-F-03-GBA-42-42-24 90L100KA5AB80S4S1F03GBA424224 90-L-100-KA-5-AB-80-S-4-S1-F-03-GBA-42-42-24 90L100KA5AB80S4S1F03GBA424224 90L100-KA-5-AB-80-S-7-C7-E-09-FAC-35-35-30 90L100KA5AB80S7C7E09FAC353530 90-L-100-KA-5-AB-80-S-7-C7-E-09-FAC-35-35-30 90L100KA5AB80S7C7E09FAC353530 90L100-KA-5-BB-60-P-3-C7-E-03-GBA-35-35-20 90L100KA5BB60P3C7E03GBA353520 90-L-100-KA-5-BB-60-P-3-C7-E-03-GBA-35-35-20 90L100KA5BB60P3C7E03GBA353520 90L100-KA-5-BB-60-P-3-C7-E-03-GBA-42-42-24 90L100KA5BB60P3C7E03GBA424224 90-L-100-KA-5-BB-60-P-3-C7-E-03-GBA-42-42-24 90L100KA5BB60P3C7E03GBA424224 In summary, there can be a number of possible reasons for a hydraulic cylinder slowdown on a plunger pump, from low fluid levels and contaminated fluid to worn components and incorrect pressure settings. Regular maintenance and inspection of your hydraulic system can help prevent these problems and keep your cylinders running smoothly and efficiently. If the problem persists, it may be necessary to seek the advice of a professional technician. Air in the hydraulic system: Air can become trapped in the hydraulic system, causing the cylinders to slow down or stop working. This can be caused by a leak in the system or improperly venting the line. To prevent this problem, it is important to ensure that the hydraulic system is properly bled and any leaks are promptly repaired. Incorrect cylinder size: If a hydraulic cylinder is not properly sized for the application, it may cause the cylinder to slow down or fail. This can be caused by factors such as incorrect cylinder bore or stroke length. It is important to ensure that the cylinder is sized for the application and meets the pressure and flow requirements of the system. Extreme Temperatures: Extreme temperatures can cause hydraulic fluid to thicken or thin, which can cause cylinders to slow down or fail. This can be prevented by using a hydraulic fluid suitable for the temperature range of the application and ensuring that the system is properly insulated or cooled where necessary. Electrical problems: Electrical problems such as a motor or power failure can cause the cylinder to slow down or stop working altogether. It is important to regularly check your system's electrical components and make sure they are functioning properly. External loads or forces: If there are external loads or forces acting on a hydraulic cylinder, such as weight or pressure from an application, it may cause the cylinder to slow down or fail. It is important to ensure that the cylinder is properly designed to handle the external load or force. In summary, there are several potential causes for piston pump cylinder deceleration. Regular maintenance and inspection of the hydraulic system, including the cylinders, can help prevent these problems and keep the cylinders running smoothly and efficiently. If the problem persists, it may be necessary to seek advice from a professional technician or contact the manufacturer for further assistance. Improper Lubrication: Improper lubrication of hydraulic cylinders can cause the cylinder to slow down or malfunction. This can be caused by using the wrong type of lubricant or insufficient cylinder lubrication. It is very important to use the lubricant recommended by the manufacturer and to ensure that the cylinder is properly lubricated according to the manufacturer's instructions. 90-L-100-KA-5-BB-60-P-4-C7-F-03-GBA-26-26-24 90L100KA5BB60P4C7F03GBA262624 90L100-KA-5-BB-60-R-3-S1-E-03-GBA-42-42-26 90L100KA5BB60R3S1E03GBA424226 90-L-100-KA-5-BB-60-R-3-S1-E-03-GBA-42-42-26 90L100KA5BB60R3S1E03GBA424226 90L100-KA-5-BB-60-S-3-C7-D-03-GBA-45-45-24 90L100KA5BB60S3C7D03GBA454524 90-L-100-KA-5-BB-60-S-3-C7-D-03-GBA-45-45-24 90L100KA5BB60S3C7D03GBA454524 90L100-KA-5-BB-60-S-3-C7-E-03-GBA-42-42-24 90L100KA5BB60S3C7E03GBA424224 90-L-100-KA-5-BB-60-S-3-C7-E-03-GBA-42-42-24 90L100KA5BB60S3C7E03GBA424224 90-L-100-KA-5-BB-60-S-3-C7-E-03-GBA-45-45-24 90L100KA5BB60S3C7E03GBA454524 90L100-KA-5-BB-60-S-3-C7-F-04-GBA-35-35-24 90L100KA5BB60S3C7F04GBA353524 90-L-100-KA-5-BB-60-S-3-C7-F-04-GBA-35-35-24 90L100KA5BB60S3C7F04GBA353524 Improper Alignment: If a hydraulic cylinder is not properly aligned, it can cause the cylinder to slow down or malfunction. This can be caused by factors such as incorrect installation or adjustment of the cylinder or improper alignment of the application. It is important to follow the manufacturer's instructions for installing and adjusting the hydraulic cylinder and to ensure proper alignment for the application. Wear or damage to other components: Wear or damage to other components in the hydraulic system, such as pumps or valves, can cause hydraulic cylinders to slow down or fail. Regular inspection and maintenance of all components in your hydraulic system can help prevent this problem. Age or use: Over time, hydraulic cylinders can simply wear out or become damaged from frequent use or exposure to environmental factors such as heat or moisture. If the cylinder is old or has been in use for a long time, it may just need to be replaced. In summary, there can be a number of possible reasons for a hydraulic cylinder deceleration of a plunger pump, ranging from improper lubrication and alignment to wear of other components or cylinder age and use. It is important to maintain and inspect the hydraulic system and cylinders regularly to prevent problems and ensure the cylinders are running smoothly and efficiently.
