A liquid pump assembly sequence (1) the bearings were installed in the bearing box and the bearing housing. (2) of the felt ring is mounted on the bearing cap A, C and the bearing box. (3) the bearing cap B, propionyl, is mounted in the bearing housing and secured with bolts. (4) will be installed bearings bearing box wearing round nut screwed on, the shaft and bearing cover A fastening the bearing box. (5) of the shaft into the bearing seat bolted, screw on the adjusting screw and bearings installed in the bearing seat, retaining the appropriate location of the trap at the lower bearing. (6) of the coupling tube is fixed in the bearing housing, and mounted in the lower part of the coupling tube on the pump cover mounted on the impeller and tightening the lower part of the shaft, in turn mounted on the pump body front cover, and bolts, with the bearing housing at the adjustment screw adjustment impeller and the gap between the front cover, (controlled at the 1 - 1.5mm) is adjusted by the nut and bolt fastening. (7) The liquid pump motor bearing mounted in the bearing housing is secured with bolts, installed in the upper end of the shaft coupling member, and the motor coupling with the fastening screw is fastened to the head of the motor shaft, the motor mounted on the motor support, and fastened with bolts, nuts. Liquid pump (8) from the pump Publisher order asbestos pad, liquid elbow a liquid pipe pieces, and fixed on the bearing seat. The liquid pump disassembly sequence, liquid pumps closing pressure of the valve in the pipeline, relieved discharge pipe on the part of the flange coupling bolts or join to take over. Period piping removed, its length does not interfere with the lifting of the pump. 2, liquid pumps release the motor frame and motor coupling bolts, hanging to go motor. 3, remove the pump bracket bolts, spin out impeller. Remove the middle bracket, pull down the coupling. 5, remove the bearing body up and down the bearing cap, you can check the condition of the bearings. The liquid pump is started and stopped a liquid pump motor before installation should be turned on the power and check the direction of rotation must be consistent with the provisions of the direction of rotation of the pump. Observation pump installed base has a solid, all parts bolts are tightened. 3. Liquid pumps fitted with motors, disk move couplings, check whether the pump shaft and motor concentric rotation whether the severity of the irregularity to normal after the operation. Liquid pump oil marked the calcium-based butter. 5. Submerged pump starter motor, open the pressure gauge cocks, pressure gauge open the outlet valve to the desired position, when the pump at full revolutions, regulating valve opening to the desired range. 6, liquid pumps normal parking should close the outlet valve, and then stop the motor, turn off the pressure gauge. 7, liquid pumps shut down the export pipeline valves and pressure gauges. Liquid when the pump is stopped for a long run, should pump apart and wipe clean, coated with anti-rust oil properly preserved. 9, submerged pump bearing housing should ensure that enough grease, bearing temperature shall not be higher than 70 ° C.
