Generally, lift the pump in place, find the connection position with the pipeline, lift the prime mover in place, align it according to section 9 "selection and use of pump drive device" in Chapter 5, and finally tighten the connecting bolts with the base. If there are cooling water pipes and lubricating oil pipes, first connect and install them, and finally connect the pump inlet and outlet pipes, and support the inlet and outlet pipes, and then the pump installation is completed.
For large pump units, when the pump and prime mover do not share the base but separate the base, the feet of the pump and prime mover can be regarded as the base, and the base installation can be carried out together with the unit installation.
IV. installation of vertical long shaft pump and deep well pump
If the vertical long shaft pump is short-term, the whole pump can be hoisted, put on the basis of the pool mouth (wellhead), find the level, tighten the foundation bolts, and the installation is very convenient.
If the length of vertical long shaft pump and deep well pump is long, in order to solve the difficulty of packaging and transportation, they are usually loose parts, so they need to be assembled and installed on site. The vertical long shaft pump deep well pump is generally installed on the wellhead or pool mouth, so two square wooden frames shall be prepared on the wellhead before installation, and two pairs of installation splints shall be provided. During installation, first assemble the pump head, clamp the upper end of the pump head with a splint, hang it on the splint with a steel wire rope, put it into the wellhead, then drop it, put the splint on the two square trees on the wellhead, and take away the steel wire rope. Connect the intermediate transmission shaft, install the intermediate bearing bracket with guide bearing, and then use another pair of splints to clamp the lifting water pipe to lift it, put it down through the transmission shaft, and connect the pump and the lifting water pipe. If you want to save the lifting height, you can put the transmission shaft in the middle of the lifting water pipe and lift it down together. First connect the transmission shaft, then connect the lifting pipe, as shown in Fig. 6-5. Then lift the installed part, take down the lower installation splint, slowly drop it, and lay the upper splint on two square timbers. According to this method, the middle transmission shaft and the water lifting pipe are lengthened one by one and put down. After installing the lifting pipe, connect the upper moving shaft, drop the pump seat through the transmission shaft and connect it with the lifting pipe, lift the pump seat and remove the splint on the lifting pipe. Put the pump base on the prepared wellhead to find the level, tighten the foundation bolts, and finally install the shaft seal, bearing component coupling, motor bracket and motor.
