Abstract

The invention discloses a vacuum pump system and method for adjusting the working fluid flow. The vacuum pump system comprises a vacuum pump pipeline, a working liquid flowmeter, a variable-frequencybooster pump, a pump outlet pressure gauge, a pump outlet platinum resistance thermometer and the like; and working fluid of a current power plant system is directly driven by the pressure of the system to enter a pump, and the flow of the working fluid entering the vacuum pump is difficult to adjust. According to the system, a booster pump and a high-precision flowmeter are additionally arrangedon an input pipeline of the working fluid, so that the pressure of the working fluid can be effectively adjusted, accurate flow change can be obtained through pressure adjustment, the working fluid entering the pump body of the vacuum pump is increased when the working fluid of the vacuum pump is insufficient, the suction capacity of the vacuum pump is improved, and the working efficiency of the vacuum pump is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of energy saving and consumption reduction of coal-fired units, and in particular relates to a vacuum pump system and method for adjusting the flow rate of working fluid. 【Background technique】 [0002] The power plant vacuum pump is an important auxiliary equipment of the power plant, which is used to improve, generate and maintain the vacuum of the turbogenerator unit. The water ring vacuum pump is composed of impeller, pump body, suction and exhaust disc, water ring formed by water on the inner wall of the pump, suction port, exhaust port, auxiliary exhaust valve, etc. The impeller is installed eccentrically in the pump body. When the impeller rotates, the water entering the water ring pump body is thrown around by the impeller. Due to the centrifugal force, the water forms a closed water chamber of equal thickness similar to the pump cavity. ring. [0003] The working fluid of the current vacuum pump...
