When the oil suction vacuum of the plunger pump is too high, the flow output will be low. The following are the effects of excessive suction vacuum on flow output: 1. Cavitation: Cavitation will occur if the oil suction vacuum is too high. When the pressure at the oil suction port is lower than the vapor pressure of the hydraulic oil, cavitation will occur. Cavitation causes air bubbles to form in the fluid, resulting in reduced flow efficiency and a reduction in the volumetric output of the pump. 2. Incomplete filling of the pump chamber: High suction vacuum will cause the pump chamber to not be completely filled with fluid during each suction stroke. Incomplete filling reduces the amount of fluid pumped, resulting in reduced flow output. 3. Efficiency reduction: Excessive oil suction vacuum will increase the resistance of fluid flow in the pump. This increased resistance requires the pump to work harder to overcome the vacuum and move the fluid, which results in a lower overall pump efficiency and reduced flow output. 4. Viscosity increase effect: High oil suction vacuum will cause hydraulic oil viscosity to increase. The increased viscosity further impedes fluid flow through the pump, resulting in reduced flow output.

Increased energy consumption: When the plunger pump operates under high oil suction vacuum conditions, more energy is required to suck fluid and maintain the necessary flow. Increased energy consumption can lead to lower overall system efficiency and higher operating costs. For the problem of low flow output due to excessive oil suction vacuum, the following steps can be considered: 1. Check for blockages: Make sure there are no obstructions or blockages in the suction line or filter that could prevent fluid flow into the pump. Clean or replace any clogged filters or screens. 2. Check the oil level: Check the oil level in the pump tank or in the system. Insufficient oil quantity will cause excessive suction vacuum. Make sure the oil level is within the recommended range. 3. Check and adjust system pressure: Check the system pressure settings and make sure they are in the proper range. Excessive system pressure will result in an excessively high suction vacuum. Adjust the relief valve if necessary.

Check for leaks: Check all connections, fittings and seals for leaks that could allow air to enter the system. Air leaks can cause cavitation and high suction vacuum. Repair any leaks promptly. 5. Consult manufacturer for recommendations: Refer to manufacturer's piston pump guidelines and specifications. Follow their recommendations for suction vacuum limitation, pump speed and other operating parameters to ensure optimum performance and flow output. 6. Check oil viscosity: Verify that the viscosity of the hydraulic oil is within the range recommended by the manufacturer. If the viscosity is too high, it will lead to increased resistance and increased suction vacuum. Consider using a lower viscosity fluid to improve flow performance. 7. Evaluate the pump speed: The operating speed of the plunger pump will affect the suction vacuum and flow output. Make sure the pump is running at the manufacturer's recommended speed. Running the pump at a slower speed may help reduce suction vacuum and increase flow output. 8. Review System Design: Evaluate the entire system design, including suction lines, piping diameters and lengths. Insufficient suction line diameter or excessive line length will result in high suction vacuum and reduced flow output. Make sure the system is properly designed for optimal fluid flow. 9. Solve the problem of air leakage: air leakage on the suction side of the pump will lead to a higher vacuum degree of oil suction. Check for air leaks in suction lines, fittings or seals. Properly seal any leaks to eliminate air from entering the system and improve flow performance. 10. Assess pump condition: Inspect the plunger pump for wear, damage, or misalignment that could cause high suction vacuum. Worn or damaged parts may require repair or replacement to restore proper pump operation and flow output. 11. Consult an Expert: If you are having difficulty solving the problem yourself or if the problem persists, consider consulting the manufacturer's technical support or seeking the help of a qualified hydraulic technician. They can provide expert advice, perform further diagnostics, and recommend appropriate solutions based on the specific characteristics of your system.

Check pump efficiency: Evaluate the overall efficiency of the plunger pump. If the pump wears or develops internal leaks, this can result in a higher suction vacuum and reduced flow output. Consider inspecting the pump's internal components, such as pistons, valves, and seals, and performing any necessary maintenance or repairs to restore efficiency. 13. Assess suction line design: Check the design of the suction line and make sure it is sized and configured correctly. Suction tubing should be of sufficient diameter and free from sharp bends or restrictions that could result in increased resistance and suction vacuum. Optimize the design of the suction pipeline to promote the smooth flow of fluid into the pump. 14. Adjust pump displacement: Depending on the design of the plunger pump, adjusting the pump displacement or stroke length may help relieve high suction vacuum. Consult the manufacturer's guidelines and specifications to determine if adjusting the pump displacement is appropriate for your particular pump model. 15. Optimize pump inlet conditions: Pay attention to pump inlet conditions and make necessary improvements. Make sure the pump inlet is in an area with adequate fluid supply and minimal air entrainment. Consider adding a well-designed suction filter or inlet stabilizer to improve inlet conditions and reduce the risk of air ingestion. 16. Monitor the fluid temperature: If the fluid temperature is too high, the viscosity will increase and the suction vacuum will increase. Monitor fluid temperature and ensure it remains within recommended operating range. If necessary, implement appropriate cooling measures such as heat exchangers or chillers to maintain optimum fluid temperature. 17. Consider Alternative Pump Configurations: If the high suction vacuum problem persists despite troubleshooting efforts, consider consulting the manufacturer or a hydraulics specialist to explore alternative pump configurations or technologies that may be better suited to your specific application requirements. 18. Regular maintenance and monitoring: Implement a regular maintenance plan for the plunger pump and the entire hydraulic system. Regularly monitor oil level, system pressure and flow output for early detection of any abnormalities. Perform routine maintenance tasks such as oil changes, filter changes and component inspections to ensure optimal pump performance and prevent problems that cause high suction vacuum. By following these additional steps and taking appropriate measures, you can effectively resolve the problem of low flow output caused by high suction vacuum of the piston pump. Proper maintenance, system optimization and regular monitoring will help ensure the efficient operation and performance of your hydraulic system.
