What Are The Methods Of Cleaning Self-Priming Pumps?
TIME：2024-06-03 Author：admin Views：
Acid and alkali resistant self-priming pump cleaning is an essential part of the cleaning of the machinery has a great impact. Let us learn to use the correct cleaning method to improve the quality of cleaning and reduce costs, reduce damage. But first,we need to know how to disassemble before cleaning .
First of all, use the pulling horse to dismantle the coupling, the specific method is: with a special tool pulling horse hooked coupling, and its screw top pump shaft center, slowly turn the wrench, the coupling can be dismantled, in the process of hooking and pulling, can be used to copper hammer or copper rod lightly hit the coupling .
● Clean the water seal pipe and check whether the pipe is smooth.
● Clean the shaft tile and bearing, remove the grease, then clean the oil ring and oil level meter. Ball bearings should be cleaned with gasoline.
● The parts and components that are not assembled temporarily should be coated with oil for protection after cleaning.
Acid and alkali resistant self-priming pump disassembly methods:

Secondly, loosen the fastening bolts on the pump cover and pump body, and take out the rotor assembly from the pump body.
Thirdly,disassemble the impeller:
● Demolition of acid and alkali self-priming pump impeller need to measure the rotor axial runout and radial runout, measure the rotor axial runout and radial runout is normal and record, the rotor rotates for a week, the same measurement point of the large value of the value of the runout, that is, the runout amount of the point.
● Then disassemble the impeller back cap, remove the impeller, before disassembly to confirm the back cap rotating direction, prohibit reverse force damage to the back cap, the impeller with a pry bar pry down, pry in the impeller ribs, so as not to pry the impeller cracked, as shown in Figure 1-13, the appearance of the impeller back cap should be no biting and slippery silk phenomenon, otherwise it should be repaired or replaced.
● And then disassemble the impeller guiding flat key, flat key appearance check key should be no obvious deformation, defects and other defects, and key groove should meet the requirements, otherwise it should be repaired or replaced.
● Remove the self-priming pump cover and shaft sleeve, and loosen the bearing gland, you can pump the shaft from the suspension (note that in the use of copper rods to tap the head of the shaft, you should wear the impeller nut to prevent damage to the threads).
Cleaning methods of acid and alkali resistant self-priming pump:
● Scrape off the scale and rust accumulated on the inner and outer surfaces of the impeller, sealing ring and bearings, etc., and then clean and blow it with water or compressed air.
● Clean the grease and rust accumulated on the joint surfaces of the acid and alkali resistant pump casing.
Thirdly,disassemble the impeller:
● Demolition of acid and alkali self-priming pump impeller need to measure the rotor axial runout and radial runout, measure the rotor axial runout and radial runout is normal and record, the rotor rotates for a week, the same measurement point of the large value of the value of the runout, that is, the runout amount of the point.
