The vacuum pump unit is widely used in the production process of chemical enterprises. Because the production of chemical enterprises is accompanied by high temperature, flammable and explosive, corrosive gas, toxic and harmful substances, etc., the application performance of the vacuum pump unit is often affected by multiple factors, reducing the vacuum effect. Today, I will analyze the impact of the cooling system failure of the vacuum pump unit:
When the vacuum pump unit is running, in order to maintain the suction capacity, its sealing water must maintain a certain degree of supercooling. If the water temperature rises, the sealing water of the vacuum pump unit will vaporize, and its limit vacuum pumping value is the saturation pressure corresponding to this temperature. Although the sealing water of vacuum pump unit will not reach the saturation value in design, in actual operation, because the end difference of industrial closed cooling water system and plate heat exchanger of vacuum pump unit itself increases due to scaling, and there is no safety margin for the degree of supercooling of sealing water in design, problems will occur after a period of operation.
As the temperature of the sealing water of the vacuum pump unit is too high, its air extraction capacity will continue to decline as the sealing water temperature approaches saturation, reaching saturation and vaporization, which seriously affects the vacuum pumping capacity of the vacuum pump unit, causing air accumulation in the condenser and rising back pressure. If not noted, it will not only seriously affect the output of the unit and seriously reduce the operating economy of the unit, but also cause cavitation damage to the impeller of the vacuum pump unit due to the vaporization of the sealing water.
Therefore, in order to reduce the impact of the cooling system on the operation of the vacuum pump unit, it is necessary to take appropriate improvement measures. The cooling water system shall be modified, and the vacuum pump shall be directly cooled by circulating water to reduce the intermediate links, which can effectively reduce the temperature of the sealing water of the vacuum pump.
