Problems solved by technology

When the Roots blower is used to transport ordinary gas, the gas will partly leak from the gap between the shaft and the wall panel. This leakage has no impact on the fan and the environment; when the Roots blower is used to transport toxic gases such as gas wind, the above-mentioned Leakage will cause an accident

Abstract

The invention relates to a Roots blower wallboard. The wallboard is provided with a shaft hole; a rotating shaft is inserted in the shaft hole; an outer sleeve is arranged in the shaft hole; an inner sleeve is arranged on the shaft section of the rotating shaft, which is positioned in the shaft hole; a skeleton oil seal and / or a labyrinth seal is arranged between the inner sleeve and the outer sleeve; the skeleton oil seal sleeves the outer surface of the inner sleeve; an oil seal seat is arranged between the outer surface of the skeleton oil seal and the inner surface of the outer sleeve; the wallboard is provided with a cooling jacket filled with circulating water or a cooling cavity is formed in the wallboard. The rotating shaft is subjected to double sealing by the skeleton oil seal and the labyrinth seal and gas can be effectively prevented from being leaked from a fit clearance of the rotating shaft and the shaft hole, so that a Roots blower can implement conveying of dangerous gas.

Description

Background technique [0001] The invention relates to a roots blower, in particular to a roots blower wall panel. Background technique [0002] The three-blade Roots blower is a double-impeller synchronous compression machine. Each three-blade rotor is supported by two bearings. A pair of synchronous gears is used to keep the relative position of the two rotors constant. It is a positive displacement blower with the characteristics of forced air delivery. When a Roots blower is used to transport ordinary gas, the gas will partially leak from the matching gap between the shaft and the wall. This leakage has no effect on the blower and the environment; when the Roots blower is used to transport toxic gases such as gas wind, the above mentioned Leakage will cause accidents. Summary of the invention [0003] The purpose of the present invention is to provide a leak-proof Roots blower wallboard. [0004] The technical scheme adopted by the present invention ...
