Examples

Referring to fig. 1, the present invention provides a technical solution: a cooling system for a vacuum pump includes a cooling assembly 100 and a gas-liquid separation assembly 200.

Referring to fig. 1, the cooling module 100 is mainly used for cooling, and the gas-liquid separation module 200 is mainly used for separating cooling water from hot water (hot gas) of the vacuum pump 130, so as to prevent the cooling effect of the original cold water from being reduced after the cold water and the hot water are mixed.

Referring to fig. 1 and 2, the cooling module 100 includes a water storage tank 110, a ground pool 120, and a vacuum pump 130, wherein the water storage tank 110 is configured to store heavy water, and the vacuum pump 130 is cooled by using waste heavy water instead of tap water, thereby completely solving the problem of tap water waste. Wherein, the water storage tank 110 has a water inlet pipe 111 and a water outlet pipe 112, and since the water flow rate of the water inlet pipe 111 needs to be greater than that of the water outlet pipe 112, the liquid level in the water storage tank 110 needs to be controlled between 1.4M and 1.5M. The underground pond 120 is internally provided with a submerged pump 121, the water inlet pipe 111 is connected with the submerged pump 121, the water level of the underground pond 120 rises, the submerged pump 121 is automatically started, and water is pumped back to the black heavy water storage tank. The outlet pipe 112 is connected with the cooling water pipeline 131 of the vacuum pump 130, specifically, the cooling water pipeline 131 is provided with a thermometer 1311, the thermometer 1311 is configured to measure the temperature data of the cooling water pipeline 131, so as to patrol the temperature of the heavy water storage tank, if the display temperature is higher than 35 ℃, the pump needs to be stopped, hot water is emptied, fresh heavy water is newly supplied or water is changed, the temperature inside the vacuum pump 130 is effectively reduced, the scaling problem of calcium and magnesium is relieved, the service life of the pump body is prolonged, and the maintenance frequency is reduced.

Referring to fig. 1 and 2, the gas-liquid separation assembly 200 includes an exhaust pipe 210 and an overflow pipe 220 connected to the exhaust pipe 210, the bottom of the exhaust pipe 210 is a closed structure, the exhaust pipe 210 is connected to the exhaust port 132 of the vacuum pump 130, the overflow pipe 220 can extend into the ground pool 120, and since the overflow pipe 220 forms a liquid seal under the liquid level, after the hot air pumped from the vacuum pump 130 enters the exhaust pipe 210, the liquid falls down and is discharged into the ground pool 120 along the overflow pipe 220, and the hot air can only be discharged to the outside from the exhaust pipe 210, so that the problems of humidity and the like caused by the hot air discharged from the vacuum pump 130 indoors can be thoroughly solved. And for better protection vacuum pump 130, interlock the low liquid level of storage tank 110 and vacuum pump 130 power, if detect when the liquid level is lower in the storage tank 110, will stop vacuum pump 130's operation, submerged pump 121 of ground pond 120 also need set up the interlock of high low liquid level equally in addition, neither lets the cooling water extravagant, can prevent again that the liquid level is too low, submerged pump 121 idle running, leads to the pump body to damage.

Specifically, the working principle of the cooling system for the vacuum pump is as follows: when the water storage tank 110 is used, the water in the water storage tank 110 flows into the vacuum pump 130 through the water outlet pipe 112 and the cooling water pipe 131 under the negative pressure action of the vacuum pump 130, so that the water in the water storage tank 110 can be used as cooling water to cool the vacuum pump 130, meanwhile, as the vacuum pump 130 operates, hot air pumped out can enter the exhaust pipe 210 through the air outlet 132, because the overflow pipe 220 forms a liquid seal under the liquid level in the ground pool 120, the hot air enters the exhaust pipe 210, the liquid falls down and is exhausted into the ground pool 120 along the overflow pipe 220, the hot air is directly exhausted outdoors from the exhaust pipe 210, after the water in the ground pool 120 is cooled, at the moment, the water level of the ground pool 120 also rises correspondingly, the submerged pump 121 is started, the water is recovered into the water storage tank 110, and the water is recycled;

when the cooling water in the water outlet pipe 112 enters the vacuum pump 130 through the cooling water pipe 131, the temperature of the cooling water can be visually observed through the thermometer 1311, so that the water storage tank 110 can be filled or the water can be changed in time.

It should be noted that the specific model specifications of the vacuum pump 130 and the submerged pump 121 need to be determined by model selection according to the actual specification of the apparatus, and the specific model selection calculation method adopts the prior art, so detailed description is omitted.

The power supply and the principle of the vacuum pump 130 and the submerged pump 121 are clear to a person skilled in the art and will not be described in detail here.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
