Frequently Asked Questions
How to check for leaks in PV7 pump pipe connections?
Inject 0.5-1MPa compressed air into the system and apply soapy water to seals; check for bubbles.
Can the PV7 pump's rotation direction be reversed?
No, reverse rotation causes vane jamming and seal damage; verify with the nameplate arrow before startup.
How to verify the motor rotation direction for the PV7 pump?
Use "jogging" (1-2 seconds of power supply) to observe rotation; adjust wiring if reversed.
What is the requirement for the PV7 pump's drain line?
The case drain line must be routed below the tank liquid level to ensure smooth oil return; do not reuse drain oil for suction.
