The invention discloses a novel high-pressure roller Roots blower, which comprises a cylinder body, wherein the cylinder body is a hollow cylinder; a main oil tank is connected to one lateral surface of the cylinder body, and an auxiliary oil tank is connected to the other lateral surface of the cylinder body; the main oil tank and the auxiliary oil tank are hollow hemispheroids; wallboards are connected to the two lateral surfaces of the cylinder body, one of the wallboards is arranged in a cavity in the main oil tank, and the other wallboard is arranged in a cavity in the auxiliary oil tank; an air inlet is formed on the upper surface of the cylinder body, and an air outlet is formed on the lower surface of the cylinder body; an inner cavity like the figure '8' is formed in the cylinderbody; left and right ends of the inner cavity are connected with the cylinder body by ribbed plates; a cavity between the inside of the cylinder body and the inner cavity is divided into an upper cavity and a lower cavity by the ribbed plates; the upper cavity is communicated with the air inlet, and the lower cavity is communicated with the air outlet; and two support plates are symmetrically arranged on the outer surface of the lower part of the cylinder body. The novel high-pressure roller Roots blower has the advantages of simple structure, large bearing pressure and improvement on work efficiency and service life.
Description
technical field [0001] The invention relates to a volumetric rotary blower, especially a high-pressure Roots blower, which is suitable for various industries and departments such as metallurgy, chemical industry, petrochemical, instrument, building material, petroleum, mine, textile, gas station, and pneumatic conveying. Background technique [0002] At present, the traditional Roots blower is mainly composed of cylinder body, wall panel, rotor, synchronous gear, bearing, seal, oil tank and other parts, and the shaft extension part is sealed by mechanical seal. The working chamber is composed of a cylinder, a rotor, and a wall panel. Its working principle is: under the action of the synchronous gear installed on the shafts of the two parallel rotors, the two parallel rotors in the cylinder rotate in opposite directions relative to each other. Due to the appropriate working gap between the impellers and between the impeller and the cylinder body and the wallboard, the intake ...
