Industrial Rotary Air Compressors

The industrial rotary air compressor adopts a two-stage main engine with a unique main engine design. The first-stage compression unit and the second-stage compression unit are integrated into one body. They are driven by gears so that the rotors of each stage of the compression unit can obtain linear speed.

The rotor profile reduces leakage area and improves compression efficiency.

Between the primary and secondary compression chambers, oil injection cooling is introduced to replace the intercooler, which significantly reduces the loss of compressed air. At the same time, the dew point temperature of the compressed air is controlled to prevent liquid water from entering the secondary main engine and causing corrosion, and it also prevents oil of emulsification.

Both the primary and secondary main engines have introduced a partial axial air inlet design, making full use of the effective length of the screw to maximize compression efficiency; reduce radial unbalanced forces and improve component life; and also significantly reduce operating noise.

Features of two-stage screw air compressor air compressor:

The two-stage screw air compressor can achieve common power system exhaust pressures with only a single stage of compression. However, from the perspective of energy consumption, using two-stage compression can effectively reduce energy consumption. For this reason, two-stage compression models have been introduced among oil-injected screw air compressors above 90kw. Under the same power, a two-stage compression oil-injected screw air compressor can produce 12%-18% more air volume than a single-stage compression oil-injected screw air compressor. In other words, when compressing the same air volume, two-stage compression can save an average of 15% of power than single-stage compression. The two-stage compression oil-injected screw air compressor is not only more energy-saving than the single-stage oil-injected screw air compressor. Moreover, due to the low compression ratio of each stage, the small force on the rotor and bearings, the large diameter of the rotor and the low speed, so

Two-stage compression screw air compressor super cooling oil:

Under normal operating conditions, it only needs to be replaced every 8,000 hours or 2 years, which greatly reduces operating costs.

High separation, reducing the amount of oil in the gas by half

Good thermal conductivity for better cooling effect

High flash point (271℃), making operation safer

Not easy to accumulate carbon and dirt, making the service life longer

The two-stage compression screw air compressor adopts an efficient oil and gas separation system:

The efficient two-stage oil and gas separation system reduces the oil content of the outlet compressed air to only 3ppm. Moreover, the oil filter and the oil and gas cylinder are integrated together to make the internal structure compact, which effectively solves the problem of oil leakage.

Stage filtration uses mechanical separation, so that about 95% of the oil is separated through a complete separation system.

The multi-layer glass fiber filter element used in the second stage filtration makes the compressed air quality better and ensures lower oil content.

Rotary compressors are generally divided into

 

1. Screw compressor

Screw compressor is a type of rotary compressor. It consists of two parts: a stator and a rotor. The gas compression process is completed through the meshing between them. The screw compressor has a simple structure and smooth operation, and is suitable for compression in refrigeration, air conditioning and industrial gases.

 

2. Scroll compressor

The scroll compressor consists of a fixed scroll impeller and a rotating rotor. The gas is accelerated by the rotating impeller and then further compressed by the rotor. Scroll compressors are suitable for high-pressure ratio compression and are often used in gas turbines.

 

3. Rotary vane compressor

A rotary vane compressor is a mechanical device that compresses gas. It pushes the gas to a pressure outlet through a set of rotating impellers. The rotary vane compressor has small vibration, low noise and easy maintenance when working, but its compression degree is not high and its use range is narrow.

 

4. Rotor compressor

Rotor compressors are driven by an engine or electric motor (mostly electric motors), and the other rotor (also called the female rotor or concave rotor) is driven by the oil film formed by the main rotor through oil injection, or by the end of the main rotor and the concave rotor. Synchronous gear drive at the end.
