Seven pumps use methods and precautions 1. The pump should be carefully checked before using the pump and motor for damage. Check the tightness of fasteners. 2. Barring pump friction sound check. Also check the pump shaft and motor shaft concentricity. Two cylindrical coupling deviation does not exceed the number of 0.5mm3. Access to pump out the liquid outlet pipe should be a separate bracket. prevents it from being added to the weight of the pump body. The pump in the absence of exceptional circumstances must be equipped with automatic pump control cabinet. Do not directly linked to the grid or use the knife switch to turn on the current. .5 Ensure the normal operation of the pump. The pump may not be in the low lift state long run (general use Head of not less than 60% of rated lift). The best control in the proposed use within the lift range. prevent overloading due to burn out the motor pump eight pump maintenance 1. someone should manage and use. and regularly check the pump Whether the circuit and pump is working properly. 2. Each time you use especially for thicker more viscous slurry after. Consumers should be placed in the water pump running for several minutes. Prevent sediment left in the pump guarantees Cleansing pump. Should fill or replace the oil in the oil chamber (10-30 # oil) 3. In the normal state. Pump every 300-500 hours. The mechanical seal to maintain good lubrication. Improve the mechanical seal life. 4. The seal between the pump impeller and the ring having a sealing function. The sealing ring is damaged will directly affect the performance of the pump. Necessary, replaced.
