If the external relief valve of the plunger pump is set too low, it will indeed cause the system to respond slowly. The reasons are as follows: 1. Pressure limiting function: The external relief valve is designed to limit the maximum pressure in the hydraulic system by flowing excess fluid back to the tank when the system pressure exceeds the set limit. This helps protect the pump and other components from damage due to excessive pressure. 2. Pressure relief delay: When the relief valve is set too low, it means that the system pressure needs to reach a lower threshold before the relief valve opens. Therefore, the pressure relief valve will be activated late in the system operation, thereby delaying the pressure relief process. 3. Slow system response: The pressure relief delay caused by the low relief valve setting will cause the hydraulic system to respond slowly. When system pressure increases beyond desired levels, the relief valve takes longer to open and divert excess fluid flow. This delay affects the system's ability to respond quickly to changes in load or command signals.

Increased pressure spikes: If the relief valve is set too low, the system pressure may continue to rise beyond the desired level before the relief valve finally opens. This can cause pressure spikes, or sudden increases in pressure. These pressure peaks can negatively impact system performance, potentially causing vibration, instability, and even damage to components. 5. Impaired function of other system components: The slow response caused by a low setting relief valve can also affect the function of other components in the hydraulic system. For example, if a relief valve is part of a closed-loop control system, delaying relief may affect the response of other control elements, such as actuators or valves, causing the system to run slowly or inaccurately. 6. Increased load on the pump: When the safety valve is set too low, the pump will be subjected to higher working pressure before the safety valve opens. This increases the load on the pump, which over time can lead to increased wear and reduced pump efficiency. The pump may have difficulty maintaining the required pressure and flow, resulting in decreased overall system performance. 7. Inefficient power consumption: A low setting relief valve can cause the pump to overwork, resulting in inefficient power consumption. The pump may expend more power to overcome higher pressure resistance before pressure relief occurs. This inefficiency leads to increased energy consumption and increased operating costs.

Potential system overload: If the relief valve cannot open at the required pressure because it is set too low, the system may experience an overload condition. This occurs when the pressure exceeds the maximum capacity of the pump or other system component. System overloading can lead to equipment failure, reduced reliability, and potential safety hazards. 9. Impact on control and stability: If the overflow valve is set too low, the system will respond slowly, which will affect the overall control and stability of the hydraulic system. Delayed pressure relief can result in delayed or inaccurate actuator control, resulting in compromised system performance, reduced accuracy and potentially unstable operation. 10. Pressure fluctuations and noise: Relief valves set too low may cause pressure fluctuations in the hydraulic system. When a safety valve opens and closes in response to fluctuating pressure, it creates noise and vibrations within the system. These pressure fluctuations and associated noise can adversely affect overall system performance and can even cause damage to sensitive components. 11. Inefficient system performance: Low setting safety valves can lead to inefficient system performance. When a relief valve opens later than expected, overpressure builds up in the system. This can lead to inefficiencies such as increased energy consumption, heat generation, and reduced overall system efficiency. It can also limit the system's ability to respond quickly to changing demands or operating conditions. 12. Potential component damage: Delayed pressure relief due to a relief valve set too low can subject various system components to higher than expected pressures for extended periods of time. Prolonged exposure to high pressure can cause damage to components, including seals, valves, hoses and other hydraulic system components. It accelerates wear and reduces the overall lifespan of these components.

Reduced system safety: A safety valve with a low setting may compromise system safety. If the relief valve fails to open at the required pressure, it can cause overpressure, which can lead to catastrophic system failure or damage. This could pose a safety risk to personnel and equipment operating within the hydraulic system. 14. Insufficient Control Response: Slow response caused by setting the safety valve too low can affect the ability of the system to maintain precise control. For example, in systems that require precise pressure regulation, such as in hydraulic presses or positioning applications, delayed pressure relief can result in inaccuracy, poor control response, and decreased system stability. 15. Increased maintenance and downtime: Improperly set safety valves can lead to increased maintenance needs and potential downtime. If a system experiences issues such as component damage or system failure due to overstressing, extensive repairs, component replacement, or even system redesign may be required. This can lead to increased maintenance costs and unplanned production interruptions. To alleviate these problems, the relief valve must be set to the appropriate pressure level based on system requirements and specifications provided by the pump manufacturer. Relief valves must be inspected, adjusted and maintained regularly to ensure optimum system response, efficiency and safety. In addition, monitoring system pressure and response time can help identify various problems related to safety valves and take corrective action accordingly.
