Installation of supporting water pump in clean room
A small integral centrifugal pump is usually used in the air-conditioning water system, which is mainly used for the circulation of cold and hot medium and cooling water system; the foundation of civil construction should be reviewed and accepted before construction, especially the foundation size, elevation, axis, reserved holes It should meet the design requirements, the foundation surface is flat, and the strength meets the equipment installation requirements; before the water pump is installed, check the name, specification and model of the water pump, and the appearance of the water pump should be in good condition, free of rust and damage. Check whether the parts are complete and whether there is any defect or rust; manually crank the pump, the crank should be flexible, and there should be no jamming or abnormal sound; when the pump is hoisted, the hook, rigging, and wire rope should be hung on the base or pump body And the lifting ring of the motor, it is not allowed to hang on the shaft, bearing seat or the inlet and outlet flanges of the pump or motor.
Before installing the pump, clean the dirt on the concrete foundation, check again whether the size, location, and elevation of the foundation meet the design requirements, check the size of the pump base and the size of the concrete foundation, the anchor bolt holes of the base and the reserved anchor bolts of the foundation Whether the size and position of the holes are consistent, the levelness of the foundation plane should meet the requirements of the relevant specifications; the hoisting water pump is located on the foundation, install the anchor bolts, level and align with a flat shim, and then screw on the nut for secondary grouting; The anchor bolts should be installed vertically. The distance between any part of the bolt and the hole wall is greater than 15mm. The bottom end should not touch the bottom of the hole. The oil and oxide scale on the bolt should be cleaned up. The base should be in close contact, and the nuts should be tightened when the strength of the concrete reaches more than 75%. The tightening force of each nut should be the same; there should be a set of pads next to each anchor bolt, and each set of pads should not exceed three. Each group of pads should be pressed tightly. After the pump is leveled, the pads should be firm with each other, and the pads should be exposed 10-30mm from the outer edge of the base. The length of the pads inserted into the pump base should exceed the center of the anchor bolts. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean workshops. It has qualifications in decoration, electromechanical installation, and purification industries, and has many successful cases.
When installing a water pump with vibration isolation requirements, in addition to rubber flexible joints on the pump inlet and outlet pipes and elastic supports and hangers for pipe brackets, vibration isolation pads and shock absorbers can also be installed on the pump base; The rubber vibration isolation pad of the water pump is suitable for the horizontal centrifugal pump with the motor power less than 110KW and the working environment temperature less than 42 ℃; the rubber vibration isolation pads of each support point of the pump base should be an even number and arranged according to the central axis of the pump Around or around the base, the load of each support point should be uniform; the area, hardness and number of layers of the rubber spacer for each fulcrum of the same pump should be exactly the same; the vibration damping part under the pedestal should be placed in the position required by the design or standard drawing , place a cushion block slightly larger than the height of the shock absorber next to it, then hoist the water pump and install it in place, and remove the cushion block after the pedestal is raised; when the water pump is adjusted and leveled, piping and other constructions, place the shock absorber next to the pedestal shock absorber. For pads with the same height, remove the pads after the pump adjustment and piping are completed.
