Features, advantages and applicable industries of oil-free water lubricated screw air compressor

Under the general environment of national policies, the government, on the one hand, advocates energy conservation and emission reduction through incentives such as incentives and subsidies to encourage users to reduce energy consumption and promote low-carbon emissions; On the other hand, the industry quality specifications of manufacturing enterprises are improved from time to time, and the corresponding detection techniques and instruments are becoming more and more accurate, forcing enterprises to further improve product quality. As the oil-bearing screw air compressor cannot meet the gas demand of sophisticated users, it is also difficult to pass the national environmental assessment specification. Therefore, in recent years, water lubricated oil-free screw air compressor has been developed unprecedentedly.

The oil-free air compressor is different from the micro oil air compressor. Both the working principle and the lubrication method are quite different from the traditional screw air compressor. Zhuoying Machinery (Shanghai) Co., Ltd. specializes in producing single screw oil-free screw air compressor with water lubrication. The following is a detailed introduction to the working principle and advantages of oil-free water lubricated single screw air compressor.

Basic principle: a cylindrical screw and two symmetrical planar star gear bodies form a meshing pair. Generally, there are six screw grooves on the screw, and each star gear tooth divides the screw grooves engaged with it into upper and lower spaces, respectively realizing the working process of the compressor. As there are two star gear teeth, the single screw compressor is equivalent to a six cylinder double acting piston compressor. Because the cylindrical screw is symmetrically arranged with the star wheel body, it has balance, so its axial force and radial force can offset each other.

Features, advantages and applicable industries of oil-free water lubricated screw air compressor

characteristic

1. Reasonable structure and ideal force balance

Both sides of the screw of the oil-free air compressor are equipped with a star wheel body symmetrical layout, so that the oil-free air compressor not only has no unbalanced inertial force, but also the axial force and radial force used on the screw offset each other, making it have ideal force balance.

2. High efficiency

In theory, oil-free air compressor has no clearance volume, large unit capacity and ideal isothermal compression. Due to the good thermal conductivity of water, the temperature of lubricating water when injected into the compression chamber will drop to 45 ℃, close to the suction temperature.

3. Compressed gas does not contain oil

Use water instead of oil to achieve the functions of lubrication, cooling, sealing and noise reduction, and provide high-quality oil-free air without pollution. The discharged water does not need special treatment to meet the environmental requirements.

4. Low noise and small vibration

The superior dynamic balance system of oil-free air compressor can effectively control the vibration source. The stable operation has no special requirements for the foundation and low operating noise.

5. Long service life of main engine

The symmetry of the structure and the setting of flow holes enable the balance of the radial and axial forces generated by the compressor during operation, so the rotor bearing load is small, and it can operate for 50000 hours.

The above is an introduction to the working principle and advantages of oil-free water lubricated screw air compressor. This is the premise guarantee that the machine can operate normally for a long time.

advantage

Compared with other oil-free air compressors, oil-free water lubricated air compressors have obvious advantages:

1. The water is used as the compression sealing and cooling medium, and the use cost is low.

2. Through the advanced sealing and isolation technology, the compressed air is cleaner and can be pure without oil.

3. It has higher volumetric efficiency and more energy saving. It can save more than 15% energy compared with the two-stage dry twin screw and more than 36% energy compared with the primary dry twin screw.

4. Avoid the frequent occurrence of dry screw and expensive maintenance of main engine, making it more stable and reliable.

5. The noise is lower. The axial and radial forces of the single screw are balanced. The star wheel rotates freely with the screw under water film lubrication. Therefore, the main engine components operate stably under low load, ensuring low noise and durability.

6. Consumables such as lubricating oil, oil filter and oil-gas separator core are saved compared with the traditional air compressor, thus reducing the maintenance cost. (1/5 of the maintenance cost of the traditional tiny oil air compressor in one year)

7. No fuel consumption, so the use is more environmentally friendly

Applicable industries

Water lubricated oil-free air compressors are widely used in high-end industries such as aerospace, chemical industry, textile, electronics, medicine, food, bottle blowing and cap making, laboratories, high-precision instruments, photovoltaic products and new energy, as well as special process requirements.
