Screw pump with load operation, the operation should be smooth, no noise, no vibration, the motor does not exceed the current, medium flow, pressure stable, meet the nameplate requirements or meet the production needs, seal leakage meet the requirements. Screw pump is the use of screw rotation to suction and discharge liquid. The middle of the screw for the active screw, driven by the prime mover rotation, the screw on both sides of the driven screw, with the active screw for reverse rotation. The main, driven screw thread are double-headed thread. Screw pump before the test, should check the quality of the repair is in line with quality standards, record is complete and accurate; crank lightly without jam; filler gland is not skewed, seepage to meet the requirements, the inlet valve to open the self-pressure pump, emptying. Due to the mutual engagement of the screws and the close cooperation of the screw with the inner wall of the liner, one or more sealed spaces are separated between the suction and discharge of the pump. As the screw is rotated and engaged, these sealed spaces are constantly formed at the suction side of the pump, sealing the liquid in the suction chamber therein and continuously displacing in the axial direction of the screw from the suction chamber to the discharge end to be closed in the respective spaces Continued discharge of liquid, like a nut in the screw rotation is constantly moving forward, as the case, which is the basic working principle of the screw pump.
