2 Stage Screw Air Compressor

2 Stage Screw Air Compressor Manufacturer

Ordinary screw compressors use a single host to compress air from 1bar to 8bar of air. The two-stage compression screw machine divides the compression process into two stages, and uses an equal pressure ratio to set the interstage pressure, so the compression ratio of each stage is much lower than the single-stage compression ratio, the return leakage between the rotors is greatly reduced, and the volumetric efficiency And the adiabatic efficiency has been greatly improved, and the final output has been correspondingly improved.

Two Stage Variable Speed Air Compressor

The use of bipolar compression main engine is to use two sets of screw rotors with different sizes, and the equal pressure ratio is used to set the interstage pressure, so as to realize the total pressure distribution and reduce the compression ratio of each compression.

It adopts two-stage compression main engine, high-precision large rotor, low-speed design, cascaded series, independent compression, and inter-stage cooling, which saves energy by 12%-15% compared with single-stage compression main engine.
The main engine adopts the low load design of bearings and gears, and the main engine has a long service life.
The large space design of ultra-energy-saving products is a direct-connected split structure, with strong interchangeability and convenient maintenance.
Meet different application requirements and application conditions.
The two-stage compression permanent magnet variable frequency fixed air compressor is the most energy-saving product in the series, and is recommended for occasions where energy-saving requirements are extremely strict.

Two Stage Fixed Speed Screw Air Compressor

General screw air compressors can also be used in normal applications such as common power system exhaust working pressure with only unipolar compression. However, from the perspective of energy consumption and power application, the use of dual-stage compressors can effectively reduce energy consumption, thereby reducing energy consumption. Come to higher application output power and gas consumption value.

From the perspective of energy consumption and power consumption, the use of two-stage compression can effectively reduce energy consumption and bring higher power consumption and gas consumption value. For this reason, an energy-saving two-stage compression screw air compressor is introduced in the screw air compressor.

What is two-stage compression? The compression process is that the natural air enters the first-stage compression through the air filter and is mixed with a small amount of lubricating oil in the compression chamber. At the same time, the mixed gas is compressed to the interstage pressure. The compressed gas enters the cooling channel and contacts with a large number of oil cables, thereby greatly reducing the temperature. The cooled compressed gas enters the second-stage rotor and is compressed to the final exhaust pressure for two-stage compression. Finally, the compressor is discharged through the exhaust flange to complete the entire compression process.

The diversity of industrial development has led to a wide variety of air compressors. From the perspective of energy-saving air compressors, two-stage (two-stage) compressors are a rising star in the industry.

From the perspective of energy consumption and power consumption, the use of two-stage compression can effectively reduce energy consumption and bring higher power consumption and gas consumption value. To this end, among the screw air compressors, an energy-saving two-stage compression screw air compressor is introduced.

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

In fact, everyone knows that the two-stage screw air compressor uses the principle of isothermal compression. Isothermal compression will not generate a lot of heat waste, so the utilization efficiency of energy is relatively high, and the volume ratio of the host with the other two-stage compression is higher, so Gas production is also higher. In summary, two-stage compression saves power. Permanent magnet frequency conversion is relatively less reliable. If a high-power machine wants to save energy, the first two-stage compression is recommended. Below 22KW, a permanent magnet inverter can be considered.

The main engine design can combine the compression rotor and the two-stage compression rotor in one casing, and directly drive them through gears respectively, and each stage of the rotor can obtain the best linear speed. Compared with single-stage compression, two-stage compression is close to the most energy-saving isothermal compression. In principle, two-stage compression saves 58% of energy compared to single-stage compression. The internal leakage is reduced and the volumetric efficiency is improved; the other is to greatly reduce the bearing load, improve the bearing life and prolong the life of the main engine. Since the air compressor is a general-purpose machine with high energy consumption, for users with large air consumption and long-term continuous operation, the energy-saving two-stage compression screw air compressor should be given priority.
