Because the pump manufacturer is different from the model, the structure of the pump will be different. The disintegration and maintenance steps of energy -saving water pumps are roughly two. The previous one was disassembled from bottom to top, and the latter method was to remove from top to bottom.

(1) Loose the screws connected to the pipe network with the pipe network, and twist the pump body with the base.

(2) Disassemble the cooling water pipe first, and then empty the gas of the pump body.

(3) Disassemble the bolt of the pump cover, disassemble the cover cover bolt, remove the cover cover, and then hang the pump cover smoothly on the pillow wood.

(4) Remove the bearing cover on both sides, then cover the bearings up, and then hang the rotor out.

(5) Use the tool to remove the coupling.

(6) Remove the rolling bearing and the cap, and then gently knock out the bearing with a copper stick.

(7) Loose the axes on both sides and caps. After removing the axis sleeve, remove the Grandon, and then remove the components such as the filler seat, seal ring. If the impeller is more severe, the impeller can be disassembled by heating method.

(6) If the bearing walks in the outer ring, you can detect the cooperation of the bearing seat and the bearings of the end cover. When it is not good, you need to deal with the end cover bearing seat.
