1. Before starting the pump, check the inlet, outlet and steering. The direction of rotation of the pump should be consistent with the direction indicated on the product label.
2. Before the initial start-up, the pump casing should be filled with oil (through the drain port), and the coupling should be turned by hand. It should feel even and flexible when rotating. When starting for the first time, the system should be run in a liquid-free state. The purpose is to fill the system with liquid and exhaust the pumps and pipes. Only after the air in the system has been evacuated can the system be pressurized.
3. When starting for the first time or restarting after a long-term shutdown, there will be a suction phenomenon, so an exhaust valve should be installed at the output port, or the outlet flange should be slightly loosened to exclude air, and as far as possible under no-load conditions Perform a trial operation.
4. When adjusting the displacement of the variable vane pump, loosen the locknut first, then rotate the adjustment screw, and pay attention to the direction of the adjustment screw when increasing or decreasing the displacement. After adjustment, the nut should be tightened. When adjusting the pressure of the variable vane pump, you should also pay attention to the correct rotation of the pressure regulating screw when increasing and decreasing the pressure. After the adjustment, the nut should be tightened.
