Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, and in particular relates to a heating and cooling device for electric control equipment. Background Art

[0002] With the rapid development of modern industry, in the processing of electrical equipment, more and more working conditions will make the shaft and bearing of horizontal centrifugal pump work in high temperature, high pressure and high speed environment. For example, the high-speed centrifugal pump for conveying boiler hot water in power plants, the waste heat removal pump for nuclear power plants, etc. The heat of high-temperature water is transferred to the shaft and bearing, and the friction heat generated by the high-speed rotation of the bearing makes the temperature rise of the shaft and bearing much higher than the allowable working temperature rise range. High temperature will cause coking of lubricating oil, carbon deposition of sealing ring and loss of elasticity and other adverse consequences. It is urgent to cool it with a shaft and bearing device with good cooling effect. In order to prevent the bearing from moving, the bearing fixed on the shaft generally adopts interference fit. Therefore, in the process of replacing the bearing, the bearing needs to be heated. After the bearing ring expands thermally, the bearing can be inserted or pulled out on the shaft.

[0003] At present, the bearing replacement method is usually to directly heat the bearing through an open flame of gas welding. After the bearing is heated, the bearing is separated from the shaft by knocking the bearing to complete the disassembly of the bearing. However, this method has some shortcomings: 1. During the process of knocking the bearing after the bearing is heated, the bearing is in direct contact with the air, and the heat dissipates quickly. The bearing needs to be burned continuously, which consumes energy and causes great damage to the bearing, which can easily cause the bearing to be scrapped; 2. Directly knocking the bearing to separate the bearing from the shaft makes the bearing easily deformed under high temperature, affecting the continued use of the bearing and even causing the bearing to be scrapped.

[0004] Generators generally use internal fans to cool the windings, and cooling of the bearings is achieved by adding heat dissipation ribs on the end covers. This can dissipate heat for the bearings, but the heat dissipation effect is not very good. Relatively speaking, the bearing temperature rise is still relatively high, which affects the service life of the bearings. Moreover, cooling through cold air flow or coolers not only has a poor cooling effect, but also is prone to uneven cooling during the cooling process, which can cause bearing breakage.
