IMO screw pump It is a commonly used industrial pump, which is used to transport various liquids and high viscosity media. However, due to some special factors, Screw pump Blockage may occur during use, affecting the normal operation of the pump. In order to avoid the blockage of the screw pump, we can start from the following aspects:

1. Reasonably select the material and structure of the pump: select the appropriate pump body, screw and seal material according to the nature of the transmission medium to prevent the pump parts from being eroded by the medium. In addition, the risk of clogging can also be reduced by selecting appropriate screw pitch, screw groove and rotor shape.

2. Prevent solid particles from entering the pump: for media that may contain particles, pretreatment should be carried out, such as filtration and sedimentation, IMO agent To prevent particles from entering the pump and causing blockage. At the same time, filters or screens can be set to prevent particles from entering the pump body.

3. Regular cleaning and maintenance: For media that are easy to block, such as high viscosity liquid, viscous substances, etc., the pump body should be cleaned regularly to prevent media from accumulating in the pump. At the same time, maintenance work is also essential, including lubrication of screws, replacement of worn parts, etc.

4. Control the temperature and concentration of liquid: some liquids will expand under high temperature, resulting in blockage; ALLWEILER The over concentrated medium is also easy to condense and block in the pump. Therefore, reasonable control of liquid temperature and concentration can reduce or avoid blockage.

5. Conduct necessary pump flow and pressure control: excessive flow and pressure will increase the friction and compression of medium in the pump and increase the risk of blockage. Therefore, reasonably control the flow and pressure of the pump according to the process needs to avoid overload operation.

6. Monitoring and elimination of bubbles: when bubbles exist in the pump, the viscosity and resistance of the medium will increase, leading to blockage. Therefore, when using the screw pump, the bubbles in the pump should be monitored and eliminated to ensure the smooth transmission of the medium.

7. Pay attention to the start stop and circulation cycle of the pump: frequent start stop and circulation cycle will increase the risk of pump blockage, because the friction and compression of media between pump parts will make solid particles easier to gather and block. Therefore, the operation cycle of the pump should be reasonably arranged to avoid frequent startup and shutdown. ALLWEILER screw pump

In summary, to avoid the blockage of IMO screw pump, it is necessary to select appropriate pump materials and structures, prevent solid particles from entering the pump, clean and maintain the pump body regularly, control the temperature and concentration of liquid, conduct appropriate flow and pressure control, monitor and eliminate bubbles, and pay attention to the start, stop and circulation cycle of the pump. The effective application of these measures can reduce the risk of screw pump blockage and ensure the normal operation of the pump.
