Description

Technical Field

[0001] The utility model relates to the field of motor bearing cooling, and particularly to a cooling device for a motor bearing seat. Background Art

[0002] In the heating center of a factory, the boiler feed pump supporting the boiler is driven by an electric motor. Since the boiler feed pump room is mostly located in the main plant building, there are a large number of on-site steam and thermal pipeline equipment arranged, and the ambient temperature is relatively high. Especially in summer, due to the high ambient temperature, the temperature of the motor bearing continues to rise, and the temperature of the motor bearing bush is prone to exceed the standard. To control the temperature of the motor bearing and reduce a series of chain reactions such as equipment damage caused by overheating of the running feed pump motor bearing and equipment tripping, in the prior art, the ambient temperature of the pump room is mostly reduced by manual sprinkling, or an axial flow fan is added for forced cooling. However, the problems of the above solutions mainly include: manual sprinkling for temperature reduction cannot ensure that the ambient temperature is maintained at a low level, and it increases the labor intensity with an unobvious effect; adding an axial flow fan can improve the surface temperature of the motor bearing bush, but when the ambient temperature is high, the air circulation in the pump room is poor, and the overall cooling effect of the motor bearing cannot be satisfied; adding an axial flow fan does not achieve an obvious cooling effect and increases the power consumption of the equipment. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a cooling device for a motor bearing seat with good cooling effect and high efficiency.

[0004] To solve the above problems, the utility model provides the following technical solutions:

[0005] A cooling device for a motor bearing seat includes a cooling pipe penetrating through the inner cavity of the bearing seat. The connection between the cooling pipe and the bearing seat is sealed. The cooling pipe located in the inner cavity of the bearing seat is a coiled pipe. There is a gap between the coiled pipe and the oil ring in the bearing seat. The bottom of the coiled pipe is coated with an oil-resistant rubber pipe. A circulating water cooling system is provided outside the bearing seat. The water inlet end of the cooling pipe is connected to the water outlet end of the circulating water cooling system, and the water outlet end of the cooling pipe is connected to the water inlet end of the circulating water cooling system.

[0006] In this application, a through cooling pipe is added inside the front and rear bearing seats of the motor. The motor bearings are end - cover type spherical sliding bearings, using oil - ring self - lubrication. There is enough space between the coil of the cooling pipe and the lower surface of the oil ring to prevent them from colliding. An oil - resistant rubber pipe is added at the possible contact point between the coil and the bottom of the bearing seat to avoid wearing the cooling coil, extend the service life of the cooling water coil, and not affect the heat dissipation effect. By adopting the method of adding a cooling pipe to the motor bearing seat, the temperature of the motor bearing can be effectively controlled, the cooling efficiency can be improved, the risk of overheating of the running feed - pump motor bearing can be reduced, the service life of the equipment can be extended, and further the risk of temporarily externally connecting a fan for cooling measures in high - temperature seasons in summer can be reduced, the labor intensity of on - duty personnel can be reduced, and the effect of saving electricity can be achieved.

[0007] The technical solution of the present utility model further includes that the coil is a copper spiral coil, which is made by spirally winding copper pipes. Utilizing the high thermal conductivity of copper, the heat transfer efficiency between the lubricating oil and the cooling water can be accelerated, and the overall cooling efficiency can be improved.

[0008] The technical solution of the present utility model further includes that valves are provided at both the water inlet end and the water outlet end of the cooling pipe outside the bearing seat. Through valve control, when the temperature of the bearing is not high in cold weather, the water cooling can be turned off to save water.

[0009] The technical solution of the present utility model further includes that a filter is provided at the water inlet end of the coil. Installing the filter can filter out impurities in the cooling water and extend the service life of the cooling pipe and the coil.

[0010] The technical solution of the present utility model further includes that a pressure sensor is provided on the inner wall of the cooling pipe. The pressure sensor is located outside the bearing seat and at the water outlet end of the filter. The pressure sensor is used to monitor the water pressure change in the cooling pipe in real time to prevent safety risks caused by too high or too low water pressure.

[0011] The technical solution of the present utility model further includes that a temperature sensor is provided in the inner cavity of the bearing seat. The temperature sensor is used to monitor the temperature in the inner cavity of the bearing seat in real time to more accurately control the cooling device.

[0012] The technical solution of the present utility model further includes that the circulating water cooling system includes a water inlet pipe, a water storage tank, a pump, a cooling device, and a cooling water outlet pipe connected in sequence. The cooling water outlet pipe is connected to the water inlet end of the filter, and the water inlet pipe is connected to the water outlet end of the cooling pipe.

[0013] The technical solution of the present utility model further includes that the circulating water cooling system, the pressure sensor, and the temperature sensor are all communicatively connected to the controller, thereby improving the automation degree of the entire cooling device.

[0014] The beneficial effects of the present utility model are as follows: Compared with the prior art, the purpose of the present utility model is to provide a motor bearing housing cooling device with good cooling effect and high efficiency.
