Pumps (water pumps), widely used in rural areas, such as centrifugal pumps, axial pumps, submersible pumps, mixed-flow pumps, etc. exist in the use of burning machine, high energy consumption, high repair costs and increase the economic burden on users. Therefore, special mention to farmers friends wake up.
Matching power and pump rated power to match. How many kilowatts a pump needs to be made, there is a clear rule on the pump nameplate. If you do not complete, the power of power is too large, it will result in "big car", wasting power and increase costs; on the contrary, there will be "small horse drawn cart", the water flow is insufficient or overload work, damage to the parts , Can not work normally.
New machine starts pumping, wipe the pump shaft and other parts of the protective oil. Carefully check the impeller rotation is normal, the pump shaft rotation is flexible, the bearing clearance is appropriate to see the pump body joint gasket is damaged, the connection is solid parts, whether leaks. If there is a problem, it should be promptly repaired.
Pumps and power machinery should be firmly installed. So pump shaft and power shaft parallel; install the belt, you should pay attention to the loose belt in the belt to increase the efficiency of transmission work.
Driven by the motor pump pumping, prohibited in the same line 2 pumps at the same time start the job, in case the line current is too large and burn the motor.
To promptly check the water pump inlet valve is weeds blocked. Note that the water flow is normal, if problems are found, to be ruled out immediately to ensure normal operation.
Stop the pump, you must first close the pressure valve, and then stop, and remove the belt. Such as a long time down without, it is necessary to clean up the machine, the water pump completely put away. On the easy corrosion of machinery and spare parts, to be coated with protective oil to prevent rust.
