Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, and particularly relates to a bearing rapid cooling device for a water ring vacuum pump. Background Technique

[0002] A water ring vacuum pump (hereinafter referred to as a water ring pump) is a rough vacuum pump. The ultimate vacuum it can obtain is 2000 - 4000 Pa, and the vacuum degree of the unit composed of the vacuum pump can reach 1 - 600 Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which belongs to a low-pressure compressor, and its pressure range is 1 - 2×10^5 Pa gauge pressure. The water ring vacuum pump is equipped with an eccentric rotor with fixed blades, which throws water (liquid) towards the stator wall. The water (liquid) forms a liquid ring concentric with the stator. The liquid ring and the rotor blades together form a rotary variable volume vacuum pump with a variable volume. The water ring vacuum pump is a very common pump. When the motor drives the rotating shaft to work, a large amount of heat will be generated at the bearing due to friction. If it is not dissipated in time, the bearing temperature will become higher and higher, and the bearing is easily damaged. Therefore, a cooling device is generally provided in the existing water ring vacuum pump to solve this problem.

[0003] However, the existing cooling device can only reduce the bearing temperature by water cooling, and the cooling efficiency is not high. It cannot provide sufficient cooling when the pump is working at full load, and the bearing is still easily damaged and the cooling effect is not ideal. For this reason, we propose a bearing rapid cooling device for a water ring vacuum pump to solve the above problems. Content of the Utility Model

And an atomizing nozzle is arranged at the end of the water spraying pipe located inside the cooling box. By arranging the water spraying pipes, when cooling the bearing, the water sprayed out by the water spraying pipes will be atomized through the atomizing nozzles, and then the atomized water is sent to the bearing by the fan, which can quickly cool the bearing.

[0009] Preferably, a square hole penetrating through the interior of the cooling box is opened at the top of the water tank. When cooling the bearing, the backflow water can flow back into the water tank through the square hole opened on the water tank for recycling, saving water resources.
