Novel screw air compressor

Abstract

The invention provides a novel screw air compressor. An oil-gas separation mechanism of the novel screw air compressor is located on the rear portion of a shell. A control cabinet of the novel screw air compressor is located on the rear portion of the shell. A coarse separating plate of the oil-gas separation mechanism is located in the middle portion of an oil-gas separating cylinder. Multiple air inlet holes are formed in the side face of the shell. An air inlet region is formed in the side face of the shell. An output shaft of a motor of the novel screw air compressor is coaxial with a drive shaft of a main machine of the air compressor. The motor and the main machine of the air compressor form a main machine assembly. The main machine assembly is mounted on a bracket. The bracket is connected with the bottom face of the shell through an elastic buffering piece. A heat exchanger of the novel screw air compressor is located above the main machine assembly. A deflector is arranged below the heat exchanger. A permanent magnet motor is arranged below the deflector. The two sides of the permanent magnet motor are each provided with a centrifugal fan. The novel screw air compressor is small in noise and small in size, and the cooling effect of the heat exchanger is good.

Description

technical field [0001] The invention relates to a screw air compressor. Background technique [0002] The main body of the air compressor and the motor in the housing of the existing screw air compressor are arranged separately, and the main body of the air compressor and the motor are connected by connecting parts (usually couplings and other devices), which occupy a large space in the body , and there is no cushioning measure during installation, the noise is louder when the machine is running. [0003] Existing screw air compressors generally adopt the bottom surface air intake mode, that is, an air intake hole is provided on the bottom surface of the air compressor housing. This kind of air intake method is easy to suck the dust and other impurities on the ground into the air compressor; and because the bottom surface of the compressor casing is close to the ground, it will generate a lot of noise when inhaling. [0004] Screw air compressors generate a lot of heat dur...

Problems solved by technology

With this cooling method, the noise is loud, the vibration is large, and the cooling effect needs to be improved.

[0005] The oil-gas separation mechanism of existing screw air compressors mostly adopts rotary type vertical oil-gas barrels. Although this type of oil-gas barrels is relatively mature, there are still disadvantages under the increasingly fierce market competition, mainly manifested in: rough separation At the upper end of the oil and gas coarse separation barrel, the air intake component is also above the oil and gas rough separation barrel, so that the connecting pipe between the oil and gas rough separation barrel and the compressor main engine is too long, which in turn increases the manufacturing cost; the coarse separation and fine separation are superimposed on the top of the oil and gas rough separation barrel , so that the diameter of the oil and gas coarse separation barrel increases, thereby affecting the area occupied by the entire air compressor unit, resulting in waste; coarse separation and fine separation are superimposed on the top of the oil and gas coarse separation barrel, which increases the diameter of the oil and gas coarse separation barrel, and indirectly makes the oil and gas coarse The increase in the amount of refueling in buckets increases the manufacturing and maintenance costs of the air compressor
