Description
Technical Field
A gas quantity adjustable water ring vacuum pump belongs to the technical field of water ring vacuum pumps.
Background
The water ring vacuum pump is a displacement pump, a proper amount of liquid (generally water) is filled in a pump body to serve as a working medium, when an eccentrically-installed impeller rotates, the liquid is thrown to the periphery due to the action of centrifugal force to form a closed circular ring similar to the shape of a pump cavity, a closed cavity is formed between a hub of the impeller and the liquid ring, and air enters the closed cavity on the air suction side through an air suction port of a distribution plate at a certain flow rate.
In the working process of the water ring vacuum pump, if the flow rate of gas from a system pipeline is too high, the impeller is full of the cavity when rotating to a half angle of the air suction port, and at the moment, the gas continuously enters the air, and the gas in the air suction cavity is subjected to backflow under the impact of the air inlet speed, so that the air suction amount is reduced; when the air inlet pressure of the pipeline of the whole production system of a user where the water ring vacuum pump is located is reduced or the flow speed is reduced, the air flow speed from the pipeline of the system is reduced, and at the moment, when the impeller rotates through the air suction cavity of the distribution plate, if the outer boundary line of the air suction port of the distribution plate is too small, when the impeller rotates through the air suction port of the distribution plate, the air cannot completely fill the closed cavity at the air suction side, and the air suction amount of the water ring vacuum pump is also reduced. When the exhaust pressure of a pipeline of the whole production system of a user where the water ring vacuum pump is located is increased, the flow velocity of gas discharged into the system is reduced, and at the moment, when the impeller rotates through an exhaust port of the distribution plate, the gas cannot be completely discharged at the stage, so that a part of gas returns to the suction side along with the impeller cavity to occupy the volume of the suction side, the actual volume of the sucked gas at the suction side is reduced, and the air suction amount of the water ring vacuum pump is reduced; when the pipeline exhaust pressure of the whole production system of a user where the water ring vacuum pump is located is reduced, the flow velocity of gas discharged into the system is increased, at the moment, when the impeller rotates through the exhaust port of the distribution plate, the gas is completely discharged when the impeller does not completely rotate through the exhaust port of the distribution plate, a part of gas in the exhaust pipeline returns to the impeller cavity, then the impeller cavity returns to the suction side, the volume of the suction side is occupied, the actual suction gas volume of the suction side is reduced, and the air suction amount of the water ring vacuum pump is reduced.
