Background

The screw air compressor is a positive displacement type gas compression machine with a working volume doing rotary motion. The compression of the gas is achieved by a change in volume which is achieved by a pair of rotors of the compressor rotating within a housing.

In a screw compressor, a pair of spiral rotors meshing with each other are arranged in parallel in a compressor body, and a rotor having a convex tooth on the outer periphery of a pitch circle is generally called a male rotor or a male screw. The rotor with concave teeth in pitch circle is called as female rotor or female screw, the male rotor is connected with prime mover, the male rotor drives the female rotor to rotate the last pair of bearings on the rotor to realize axial positioning and bear the axial force in compressor. Cylindrical roller bearings at both ends of the rotor enable radial positioning of the rotor and withstand radial forces in the compressor. Two ends of the compressor body are respectively provided with orifices with certain shapes and sizes. One for suction, called the inlet, and the other for exhaust, called the outlet.

At present, screw air compressor machine at the in-process of work, can produce a large amount of heats in the machine, if not in time dispel the heat and cool down, the temperature that rises in the organism can indirectly influence breathe in and exhaust pressure to influence its normal work, and can reduce the life of equipment.

Detailed Description

The present invention is described in further detail below with reference to fig. 1.

Example 1: the embodiment of the utility model discloses a screw type air compressor. Referring to fig. 1, a screw air compressor machine, including

studio

3, 3 outer wall one sides of studio are equipped with ventilation cooling chamber 1, and the offside is equipped with air exhauster 10, and ventilation cooling chamber 1 can cool down the outside air, then inputs the refrigerated air of cooling into studio 3 in, air exhauster 10 then can export the high temperature gas in studio 3 to the outside to realize that studio 3 air is in the cooling state all the time.

The specific structure that the ventilation cooling chamber 1 can cool down the outside air may be: roof sets up in ventilation cooling chamber 1 and sprays board 6, sprays 6 upper ends of board and leads to pipe connection and is in ventilation cooling chamber 1 roof outside cooling water tank 5, and ventilation cooling chamber 1 left side is equipped with air intake 7, and air intake 7 connects
