How to stop when stop screw screw, turn the discharge stop valves and pumps to be stopped completely after the suction stop valve closed. Screw screw length greater because of work, less rigid, prone to bend, causing malfunction. It must be well connected to the shaft of the pair; to work best positioning after installation pump prices in order to avoid distortion caused by pipeline involved; connecting pipe should be fixed independently, to minimize the involvement of the pump and the like. In addition, spare screws, when you save the best method of fixing using suspension pump manufacturers, to avoid distortion caused due to lay flat. Maintain a constant outlet pressure screw pump is a positive displacement rotary pump, when after the outlet end is blocked, pressure will be gradually increased vacuum that exceeds a predetermined pressure value. A sharp increase in motor load at this time. Transmission machinery related parts of the load will exceed the design value of the water ring vacuum pump, can occur in severe motor burned, transmission parts break. To avoid screw damage, usually in the screw pump will be installed at the outlet of the oil return valve, the outlet pressure to stabilize and maintain the normal operation of the pump.
