Treatment Of Common Problems In Screw Pump



1.The drive shaft or motor bearing is overheated: It can be caused by a lack of lubricating oil or bearing rupture. Treatment method: Fill the lubricating oil or replace the bearing.To get more news about SEEPEX Pump Part, you can visit hw-screwpump.com official website.

2. The screw pump body vibrates violently or produces noise: Cause: the water pump is not installed firmly or the water pump is too high; the motor ball bearing is damaged; the main shaft of the water pump is bent or is different from the main shaft of the motor, and is not parallel. Treatment method: install the water pump or lower the installation height of the water pump; replace the motor ball bearing; correct the bent water pump main shaft or adjust the relative position of the water pump and the motor.

3. The screw pump does not discharge water: Cause: the pump body and the water suction pipe are not filled with water diversion; the dynamic water level is lower than that of the water pump water filter pipe; the water suction pipe is broken, and the like. The sealing surface between the screw and the housing is a space surface. There is a non-sealing region, such as ab or de, on this surface, and a number of triangular notches abc, def are formed in the groove portion of the screw, with low vibration and low noise. The notches of the triangle form a channel of the liquid, and the driving screw groove A is communicated with the grooves B and C on the driven screw rod. While the grooves b, c are in turn wound on the back side along their spiral and are in communication with the grooves d, e on the back side, respectively. And has high efficiency. The D, F, E will also be in communication due to the fact that in the sealing surface which is engaged with the groove D, E and the groove F (which is a spiral on the other side), there is also a three-angle notch a '' '' '' '' '', which is similar to the front face. In this way, the groove ABCDA forms a sealed space in the form of a single head (for example, a single-head thread is used, the groove will cut the screw in the axial direction, and the suction port is passed through to form a seal).
