Performance parameters of oil-free water lubrication screw air compressor

oil-free water-lubricated air compressor adopts the original mainframe of the water-lubricated air compressor head produced by Shanghai Granklin Group, which proves its advanced technical quality in air quality, energy saving and operation reliability.

Due to its perfect structure, it is completely symmetrical and balanced, it vibrates less and has lower noise. Completely oil-free air quality (complete machine without oil)

replacing oil with water to achieve the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality oil-free air, no pollution, and no special treatment for discharged water, which meets environmental protection requirements.

Due to the role of water, its compression is the ideal isothermal compression, the air per unit of horsepower than the general dry compressor (twin screw) to increase the output of 15%. Single machine capacity, no clearance volume single screw air compressor body is composed of a cylindrical screw and two symmetrical configuration of the plane star wheel.

the screw has 6 teeth, and the star wheel has 11 teeth. The two star wheels divide the screw into two spaces, each realizing the process of suction, compression and exhaust. Therefore, the screw compressor is equivalent to a six-cylinder piston compressor.

The screw rotates one week, each screw groove is used twice, and the screw groove space is fully utilized. Compared with other rotary compressors: the same structure size, smaller size when the displacement is the same.

No lubricating oil structure

high-performance wear-resistant silicon carbide sliding bearings, coupled with water lubrication, improve reliability.

waterway control

the use of microcomputer automatic control, including: automatic water supply, automatic drainage; automatic detection of water filters, etc., coupled with the use of high-density filters to effectively ensure the continuous operation of the compressor.

Cooling system

all models can be air-cooled and water-cooled, which is unmatched by other oil-free compressors. The special plate-fin heat exchanger is adopted, which has high energy, small volume and no maintenance cost. The low temperature difference design is adopted to avoid high temperature shutdown. The water temperature of water-cooled cooling water rope is 6-8 ℃, and the air outlet temperature is not more than 50 ℃.

Ideal isothermal compression

when the air at 20 C is compressed to 0 in an adiabatic process. 7Mpa; dry compressor because there is no cooling medium to participate in the compression, the discharge of air will be higher than 250 ℃. And we use lubricating water with cooling effect into the compression chamber, the exhaust temperature will be reduced to 40 ℃, to achieve high efficiency of isothermal compression. The moisture content in the compressed air will also decrease due to the decrease in temperature. At the same time, the lubricating water will further take away the dust in the air.

meet environmental requirements

the air compressor and other accessories are made of appropriate materials and treated to prevent rust. The compression chamber gasket is also made of advanced materials such as ceramics and carbon fiber. The high-precision water filter filters impurities efficiently to ensure that the lubricating water maintains clean water quality.

1. lifetime oil-free, good reliability

there is no lubricating oil in the main body of the oil-free water lubrication screw, and any failure of the main engine will not cause oil pollution of compressed air. Dry-type non-oil machine requires oil to participate in lubrication and sealing due to the bearings, gear box and intercooling system. Moreover, due to the high operating temperature of the unit, the seal is easily damaged. Once damaged, it will cause oil leakage, which will pollute the compressed air. It can only be continuously relied on. Maintenance and replacement of parts are guaranteed, and maintenance costs are extremely high. The company is a non-oil machine industry can promise "due to the oil pollution of compressed air, the loss caused by our company to bear" the enterprise.

2. isothermal compression, exhaust temperature does not exceed 45 ℃, put an end to the fire, and other hidden dangers

3. power consumption, water-lubricated compressor is currently on the market more energy-saving models.

4., because water participates in sealing, lubrication and cooling, the operating temperature of our oil-free screw machine does not exceed 45 ℃; all parts work at no more than 45 ℃; unlike dry-type oil-free machine, the exhaust temperature is as high as 180 ℃. At this temperature, bearings, screws, body, and sealing materials have to withstand high temperatures, so they are easily damaged and have a very short service life. If there is a slight problem with the working conditions of each part, it will produce high temperature and cause fire,.

5., due to the low operating temperature, the main machine has a long life, the maintenance cost is very low, and the failure rate is almost no.
