Product use of two-stage compression screw air compressor

At present, many screw air compressors in the traditional sense of society are single-stage compression screw air compressors, and their energy consumption and electricity consumption greatly consume a lot of electric energy and functional conversion rate. This is constantly guiding the continuous innovation and progress of the air compressor industry, enabling our air compressors to make more energy-saving long-term plans for the existing air compressors on the basis of reducing energy consumption and increasing power.

General injection screw air compressor only single-stage compression can also reach the common power system exhaust pressure and other normal use. However, from the perspective of energy consumption and power use, the use of two-stage compression can effectively reduce energy consumption and bring higher power and gas value. For this reason, in the oil-injected screw air compressor, an energy-saving two-stage compression screw air compressor is introduced.

What is two-stage compression? The compression process is that natural air enters the first stage of compression through an air filter, mixes with a small amount of lubricating oil in the compression chamber, and compresses the mixed gas to interstage pressure. The compressed gas enters the cooling channel and comes into contact with a large amount of oil mist, thereby greatly reducing the temperature. The cooled compressed gas enters the second-stage rotor for two-stage compression and is compressed to the final exhaust pressure. The compressor is discharged through the exhaust flange to complete the entire compression process.

The two-stage compression energy-saving oil-injected screw air compressor has 10%-20% more air volume than the single-stage compression oil-injected screw air compressor under the same power. In other words, under the same amount of compressed air, the two-stage compression ratio can save 5-8% of the power on average.

High-end energy-saving two-stage compression oil-injected screw air compressor is not only energy-saving than single-stage oil-injected screw air compressor, but also because of the low compression ratio of each stage, the small force on the rotor and bearings, and the large rotor diameter and low speed., So the operation is more reliable. Not only has the advantages of single-stage oil injection screw air compressor.

The two-stage compression energy-saving oil-injected screw air compressor has a host design. It combines the first-stage compression rotor and the second-stage compression rotor in a casing, and directly drives through gears respectively, so that each stage of the rotor can obtain a good linear speed, so that the compression efficiency is higher. Compared with single-stage compression, two-stage compression is close to isothermal compression with energy saving. In principle, two-stage compression can save 5 ~ 8% of energy than single-stage compression. Using two-stage compressor means using two sets of screw rotors with different sizes to realize reasonable pressure distribution and reduce each compression ratio. Low compression ratio also has several special advantages: one is to reduce internal leakage and improve volumetric efficiency; the other is to greatly reduce the load of the bearing, improve the life of the bearing, and extend the life of the host.

Two-stage compression and energy-saving fuel injection screw air compressor is different from other brands. Another feature is that it adopts a highly effective and energy-saving built-in cooling method, which not only has a good cooling effect, but also reduces the pressure loss between stages and improves compression efficiency.

In addition to the screw host, other systems and structural arrangements of the unit are exactly the same as the single-stage oil-injected screw air compressor, which brings convenience to the maintenance and use of users. As the air compressor is a large energy consumption of general machinery, so, with a large amount of gas, long-term continuous operation of the user, should give priority to the use of energy-saving two-stage compression injection screw air compressor.

As a two-stage air compressor practitioners and promoters, with its highly effective, stable, high-definition touch screen and other more user-friendly design to meet more customer needs, which is also as the air compressor industry brand value application mode.
