Pressurizing system of double-screw air blower

Abstract

The pressurization system comprises an air blower body, a screw rotor set is arranged in the air blower body, the two shaft ends of a male screw rotor and a female screw rotor are supported in the air blower body in a rotating connection mode through bearing pedestals, turbine blades are fixed to the shaft ends of the sides, close to a pressurization machine base, of the male screw rotor and the female screw rotor, and the turbine blades are fixed to the two shaft ends of the male screw rotor and the female screw rotor. A supercharging conical inner cavity matched with the turbine blade in shape is formed in the supercharging machine base. When the male screw rotor and the female screw rotor rotate in the working process, the pair of turbine blades conduct gas guiding work, the guiding-out rate of gas in an inner cavity of the air blower body is further increased, the blades on the turbine blades are all in a conical condensation shape, and a supercharging conical inner cavity matched with the turbine blades in shape is formed in the supercharging machine base; and when air enters the pressurizing conical inner cavity in the pressurizing machine base, the air pressure of the entering air is increased, and the pressurizing effect is achieved.

technical field [0001] The invention relates to the technical field of blowers, in particular to a booster system of a twin-screw blower. Background technique [0002] The twin-screw oil-free blower belongs to the volumetric gas power device. It is essentially a rotary piston machine with high working efficiency. The twin-screw oil-free blower belongs to the volumetric gas power device. The air rigidity is large, the flow rate is very stable, and the regulation is also very convenient. The superior performance of the twin-screw oil-free blower is welcomed and recognized by the majority of users. [0003] The twin-screw oil-free blower forms a working volume based on two parallel male and female rotors meshing with each other in the "∞" shaped cylinder. Through the synchronous gear, the rotor rotates in reverse at a high speed, and the working volume changes periodically with the rotation of the rotor.

Problems solved by technology

[0003] The twin-screw oil-free blower forms a working volume based on two parallel male and female rotors meshing with each other in the "∞" shaped cylinder. Through the synchronous gear, the rotor rotates at a high speed in the opposite direction, and the working volume changes periodically with the rotation of the rotor. The gas is compressed during the gas delivery process. Because the structure of the traditional twin-screw oil-free blower relies solely on two male and female rotors to compress the air, the air compression capacity is affected by the motor speed, and it is difficult to achieve a better compression effect on the air. , so there is a need for a booster system structure that improves the traditional twin-screw oil-free blast
