Injection pump with gas-liquid separation device

Abstract

The invention discloses an injection pump with a gas-liquid separation device. According to the injection pump, the gas-liquid separation device is installed in a gas-liquid separation chamber of theinjection pump, the gas-liquid separation device is formed by a reticular plate with a certain of grid density and distribution shape, and the gas-liquid separation device is clung to the outer side of an injector and extends to the wall surface of the gas-liquid separation chamber; the gas-liquid separation device of an annular reticular structure penetrates through the gas-liquid separation chamber of a whole pump casing and is installed at a certain included angle together with a horizontal plane; the top end of the gas-liquid separation device is arranged between a water outlet of the injection pump and a return inlet of the injector; and the bottom end of the gas-liquid separation device is over against the position of the return inlet of the injector, and a large mesh opening is left. According to the injection pump, in order to reduce the air content of working fluid of the injector, the gas-liquid separation device is additionally arranged in the gas-liquid separation chamber,so that the self-suction capacity of the pump is increased, and additionally, the anti-cavitation performance is improved.

Description

technical field [0001] The invention relates to a jet pump, in particular to a jet pump capable of improving gas-liquid separation efficiency, and belongs to the field of fluid machinery. Background technique [0002] Pump is a general-purpose fluid machine with abundant output, wide range of uses, and huge energy demand. Pumps can be seen in almost all industries related to industrial fluids. It transmits the mechanical energy or other energy of the prime mover to the liquid to increase the energy of the liquid, so as to achieve the purpose of conveying liquid and pressurizing the liquid. Among them, the jet pump is a pump with strong self-priming ability composed of centrifugal impeller, guide vane, ejector and water diversion chamber (gas-liquid separation chamber). The jet pump has the advantages of reliable operation, simple structure, safe and convenient use, and convenient comprehensive utilization. It is widely used in agriculture, water conservancy, electric power,...
