Clean water pump motor and pump together into a whole, motor rotor pivot bearing is water pump bearings, power transmission was rigid rotation of the pump impeller working valve. Vortex impeller and pump housing between only 0.10-0.22 mm gap, sand debris easily stuck impeller, the motor rotor can not be rotated and failure. From repairing the pump impeller failure analysis due to damage to the motor rate stuck above accounted for eighty percent. When the power switch off the motor does not turn 安国清 found wholesale pumps should promptly turn off the power when the motor is working to produce a rotating magnetic field inductance water pump factory, a short time will not damage the motor. You can use a screwdriver to remove the motor cover by hand until about rotating fan blades flexible Replace the cover and then power. Beat with a twist standings straightening this method is to use a curved concave twist stick beat shaft axis extending surface alignment. In the alignment, the axis of the concave upward, and the maximum bending convex vertex as a supporting point, strict support live, both ends of the downward pressure with the clamp, and then with 1 ~ 2 kg weight of a hammer twist rod, so that concave surface extending axis by beating. Central were the lowest since the first concave beat An Guoqing pump manufacturers, and gradually moves on both sides, and along the circumferential arc of 1/3, but more to the center tap density should be greater. Be careful not to damage the surface of the shaft when the beat. Water pump accessories wholesale, Zhejiang, water pump, water pump provided by Hebei Xin-Xin Cheng pump factory.
