Mortar pump maintenance and care precautions are what?

Mortar pump maintenance and repair methods:

1, the pump operation at the time of closing the outlet valve is called closed-pressure operation, and the closing pressure operation time of the plastic pump or lined plastic pump should be shortened as much as possible. Normal temperature medium is limited to no more than 5 minutes and high temperature medium is the best Do not exceed 2 minutes

2, sub-pump shell pump, such as the import of more than 150mm pump, the middle of the surface of the plastic seal, due to thermal expansion and contraction of some changes in size, the installation should be at the first sub-connecting bolts tighten, and then connect the inlet pipe Road, in case of surface leakage, this article is particularly important for users in the north;

3, lubricating oil should be replaced on a regular basis, usually about six months to replace;

4, to prevent the motor from damp, the motor can not have water.

5, the winter temperature is low, if there is freezing phenomenon after stopping the pump, it should be connected to the seal of the cooling water, if necessary, heated water into the thaw, then hand-drive coupling until flexible operation, and then follow the startup steps to drive ;

6, a cooling water pump device, driving should be connected before the cooling water, pump normal operation, can continue to connect, if the conditions can not be stopped, the cooling water flow and pressure are not required, tap water can ;

7, the pump can not withstand the weight of the import and export pipeline, the import pipeline is as short as possible, the pump outlet to the valve at the vertical height should be as short as possible;
