Abstract

The invention discloses a semi-closed oil injection screw supercharger. A suction end cover (1) is mounted at the outer end of a supercharger body (2); an exhaust end seat (4) is mounted at the inner end of the supercharger body (2); the other end of the exhaust end seat (4) is connected with a motor (8) through a motor connecting body (5); a female rotor (3) and a male rotor (17) are mounted in supercharger body (2); and the male rotor (17) is connected with the motor (8) through a coupler (7). Low-pressure gas (0.7-1MPa) is compressed to medium-pressure gas (3-4MPa) at high volume efficiency; a maximum volume flow of one machine can reach 72Nm<3> / min; and the complete supercharger is totally closed, and is less in wasted work, high in efficiency, compact in structure, reliable in operation, low in noise, and convenient to maintain.

Description

[0001] technical field [0002] The invention relates to an improved semi-sealed oil injection screw supercharger, which is mainly used in the field of mechanical power. Background technique [0003] Compressed gas is widely used in the field of mechanical power, especially medium pressure gas (3 ~ 4MPa). At present, piston compressors and centrifuges are mainly used for power gas in the medium-pressure field, but both piston compressors and centrifuges have the disadvantages of many wearing parts, low stability, and high maintenance costs, especially the piston compressors are noisy , oil leakage and other problems affect the normal use of users. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a semi-sealed oil-injected screw supercharger with high efficiency, compact structure, few wearing parts, reliable operation, small air flow pulsation, small vibration, low noise, no leakage, easy maintenance Convenient ...
