Frequently Asked Questions
How to adjust the output flow of the PV7-2X variable-displacement pump?
The PV7-2X is equipped with a pressure compensation or flow compensation control mechanism; adjust the set value of the compensation valve through the adjusting screw on the pump body to change the output flow of the pump.
What causes the PV7 series pump to fail to build pressure?
Possible reasons include severe internal leakage of the pump, incorrect setting of the relief valve, blocked oil suction path, damaged control valve core of the variable-displacement pump, or insufficient oil in the tank.
Can the PV7 series pumps be used in series or parallel connection?
Yes, multiple PV7 pumps can be connected in series (to increase system pressure) or in parallel (to increase system flow) under the condition of matching the motor power and pipeline diameter; it is necessary to set separate check valves and pressure relief devices for each pump.
What maintenance work should be done regularly for the PV7 series pumps?
Regular maintenance includes checking the oil level and cleanliness of the hydraulic oil, cleaning the suction filter and return filter, inspecting the tightness of the shaft seal and pipeline joints, checking the vibration and noise of the pump, and replacing the hydraulic oil and filter elements according to the maintenance cycle.
What is the material of the vanes in the PV7 series pumps?
The vanes are made of high-strength cast iron or phenolic resin composite materials, which have good wear resistance and self-lubricating properties to adapt to the high-speed sliding environment inside the pump.
