Description

Impregnating vessel for insulating paint impregnating and curing process of motor winding

Technical Field

The utility model relates to the technical field of motor winding impregnation containers, in particular to an impregnation container for an insulating paint impregnation and curing process of a motor winding. And more particularly to multilayer composite structures thereof.

Background

The impregnating and curing process of insulating paint on the motor winding 13 is an important process for manufacturing a motor, and an impregnating vessel is used as a main component of the impregnating process, and is widely applied to impregnating curing process equipment of motor windings (including transformer windings). The insulating paint is an electrical insulating resin, is liquid at normal temperature, and gels or even solidifies when the temperature rises to a specific temperature, and the motor winding needs to be preheated and dried before being immersed, so that the immersed winding can be continuously heated to the resin, and the resin in the container generally needs to be cooled to avoid the over-high temperature and the gel or even solidification in order to keep the process stable. At present, a cooling mode is commonly used, a spiral water pipe is arranged on the inner wall of a container, and circulating water with a set temperature is injected into the water pipe by a water chiller to perform heat exchange with resin in the container, so that the effect of cooling the resin is achieved. Meanwhile, the liquid level can drop due to continuous consumption of the resin, and the liquid level height needs to be detected and the resin needs to be timely replenished.

The current impregnation vessel has the common problems: 1) The cooling efficiency is lower, and the speed is slow: the spiral water pipe is adopted, so that the water pipe can only be arranged around the inner wall of the container to avoid occupying excessive space, and the temperature control is realized through heat conduction between the water pipe wall and the insulating paint and convection of cold and hot resin in the cylinder, so that the speed is low; the resin in contact with the water pipe for heat exchange occupies small proportion of all the resins in the cylinder, and the heat exchange efficiency is low; 2) The dipping process can consume resin in a container, the liquid level can be lowered continuously, the dipping depth of workpieces needs to be adjusted continuously, if in automatic process equipment, the liquid level height needs to be detected continuously and the dipping depth of each workpiece needs to be adjusted correspondingly, and the dipping depth control error is large due to the liquid level detection error and the workpiece volume difference; 3) Frequent manual replenishment of insulating paint is required or additional automatic filling equipment is adopted, so that the cost of manpower or equipment is increased; 4) When the apparatus is stopped for a long period of time, the resin in the container does not flow and is easily solidified to deteriorate.
