Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 2 and 3, a kind of main pump motor maintenance thrust collar heater, comprises terminal box 3 and heater 4.Terminal box 3 is arranged on the outer surface of heater 4, is connected with heater 4 by electric wire.Heater 4 entirety is cylindrical, and center has through hole, and sidewall is hollow structure.Heater 4 internal diameter is more than or equal to the external diameter of thrust collar 2.The hollow structure that heating tape 5 is arranged on heater 4 is inner.
Main pump motor maintenance thrust collar heater of the present utility model adopts two halves structure, and be bolted to connection, facilitate installation and removal, its internal diameter coordinates with thrust collar 2 crest clearance, is conducive to heat transfer but does not occur stressed.
In the present embodiment, heating tape 5 adopts casting aluminium material to make.
When needing to remove thrust collar 2, thrust collar heater is mounted to the outer ring of thrust collar 2, terminal box 3 is connected with power supply.After being heated to preset temperature, by thrust collar 2 and the lifting of thrust collar overall heater.
When needing back dress thrust collar 2, thrust collar 2 is placed on platform, installed thrust dish warmer, terminal box 3 is connected with power supply.After being heated to preset temperature, measure the swell increment of thrust collar 2 internal diameter, meet coordinate require after entirety to sling thrust collar 2 and thrust collar heater, be arranged on motor shaft 1.
The utility model comprises terminal box 3 and heater 4.In the disintegration demolishing process first of Qinshan two factory owner pump motor, use this covering device to heat thrust collar, make its thermal expansion amount reach the requirement of removing and installing, be successfully made and remove and return dress work, avoid the damage of equipment.
