Generally, the so-called pump head should contain the pump body and pump cover part. Pump body is mainly connected to the pump rotor, the impeller through the bearings, seal, bearing components connected. The pump cover is a part of the corresponding part of the pump body, and a closed cavity is formed together with the pump cover. The pump body and the pump cover is internally lined slurry pump. The lining of the material is generally rubber and high chromium alloy, according to the general conditions of industrial and mining conditions to choose the pump is a rubber or metal lining.
1. When the pipeline pump starts to close the outlet valve, open the inlet valve, the pump must be filled with material, not allow leakage.
2. Pump start test, check the direction of rotation, right after the opening, the pump operation.
3. Adjust the outlet valve opening, so that the pump in the rated flow, head of the operating conditions.
4. Close the outlet valve, and then cut off the power supply. If the ambient temperature is below the freezing point of medium, should pump the liquid out, to avoid the cracking equipment.
