There are several potential causes for slow response of piston pump working parts
There are several potential causes of slow response from the working parts of a displacement pump. Here are some common factors to consider: 1. Fluid viscosity: The viscosity of the fluid being pumped will affect the response time of the plunger pump. Higher viscosity fluids create more drag than lower viscosity fluids, resulting in slower response times. It is important to ensure that the pump is designed and sized for the viscosity of the fluid being handled. 2. System back pressure: Excessive back pressure in the hydraulic system will slow down the response time of the plunger pump. Restrictions, narrow passages, or improperly adjusted pressure controls in the system can cause back pressure. Make sure the system is properly designed and all components are sized and adjusted correctly to minimize back pressure. 3. Pump wear or damage: Over time, the working parts of the plunger pump, such as the plunger, cylinder and seals, may wear or become damaged. This can lead to increased internal leakage and reduced efficiency, resulting in slower response times. Regular maintenance and inspection of pump components is essential to promptly detect and address any wear or damage. 4. Insufficient lubrication: Insufficient lubrication of the working parts of the pump will lead to increased friction and slower response time. Make sure the pump is properly lubricated according to the manufacturer's guidelines and recommendations. Insufficient lubrication can lead to premature wear and reduced efficiency.

Control system problems: Problems with the control system or control mechanism will also cause the plunger pump to slow down the response time. This could include problems with the control valve, control signal, or electronic control unit. Check control system components, connections and signals to ensure they are functioning properly and sending appropriate commands to the pump. 6. Improperly sized pump: If the plunger pump is undersized for the application or system, it may be difficult to deliver the required flow and pressure in a timely manner. Make sure the pump is correctly sized and matched to the specific requirements of your hydraulic system to ensure optimum performance. 7. Temperature effects: Extreme temperatures, whether too high or too low, can affect the performance of the pump and its working parts. Excessive heat can cause fluid thinning or a change in viscosity, while extreme cold can increase fluid viscosity and reduce lubrication. Make sure the pump and fluid are operating within the recommended temperature range. 8. System Leakage: Excessive internal or external leakage within the hydraulic system can cause the plunger pump to slow down its response time. Worn seals, damaged connections, or failed components can cause leaks. Check the system for any signs of leaks and fix the problem by replacing seals, tightening connections, or repairing/replacing faulty components.

Insufficient pump priming: Improper or incomplete pump priming will result in slower response times. Make sure the pump is filled with the proper fluid before running. Insufficient priming can cause cavitation or cavitation, affecting pump performance and response. 10. Control system setting: The setting and adjustment of the control system (including pressure control device and flow control valve) will affect the response time of the plunger pump. Check that these components are properly calibrated, adjusted and set within the desired operating parameters. 11. Drive system issues: Drive system issues, such as misalignment, worn couplings, or motor issues, can cause slower response times. Inspect drive system components, including motors, couplings, and related mechanical components, and correct any problems found. 12. Contamination: Contamination within the hydraulic system can affect the performance and response of the plunger pump. Foreign particles or debris can clog or restrict the flow path, resulting in slower response times. Monitor regularly and maintain proper filtration to prevent contamination problems.

System design: The overall design of the hydraulic system will affect the response time of the plunger pump. Undersizing piping, improper component placement, or inefficient system layout can introduce unnecessary flow restrictions and slow response times. Make sure the system is well designed with properly sized components and efficient fluid pathways. 14. Operating conditions: Operating conditions such as system temperature, ambient temperature and load changes will affect the response time of the plunger pump. Extreme temperatures or rapid load changes can affect fluid characteristics and pump performance. Ensure pump operating conditions are within recommended ranges and make necessary adjustments as needed. When troubleshooting slow response of piston pump working parts, it is important to systematically evaluate each potential factor and resolve any issues found. If the problem persists or is beyond your expertise, it is recommended to seek help from the manufacturer, Danfoss or its authorized representatives. They can provide expertise and guidance to help diagnose and resolve slow response problems unique to displacement pumps.
