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. Performance parameters of Sihong medium pressure non-oil and water lubrication screw air compressor
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.
Frequency conversion air compressor power saving? To ask whether the frequency conversion air compressor saves electricity, but also depends on the machine structure and product quality of the air compressor manufacturer. The same screw air compressor, the difference between different manufacturers is still very big. Starting from the parts used in the products, small factories pay more attention to the price, take the low price route to do the market, and earn some maintenance costs by replacing parts after sales.

View detailsSingle screw air compressor is a leader in the modern air compressor industry, and its working principle is better than that of twin screw air compressor. Shanghai Granklin Group is a factory specializing in the production of water-lubricated oil-free single screw air compressors. It is an industry leader in the industry of water-lubricated oil-free single screw air compressors. From research and development to production and sales, Granklin Group integrates all-round service users.
View detailsAt present, the completely oil-free air compressor equipment that can be seen in the market mostly adopts two schemes: "water lubrication oil-free" or "dry oil-free". Different lubrication methods lead to great differences in power consumption and machine loss and maintenance of oil-free air compressors.
View detailsThe maintenance methods and precautions of the air compressor are as follows: The maintenance of the air compressor is divided into small maintenance and large maintenance. The depth of the process components of the air compressor is the same and different. The following is a common and practical air compressor maintenance method and Precautions.
Compressor is an essential power equipment for chemical and petrochemical production. From the energy point of view, the compressor is a machine that converts the power energy of the prime mover into gas pressure energy. With the development of science and technology, the application of pressure
As a commonly used power source in factories, air compressors mainly supply pneumatic valves, instruments, cylinders and other equipment to provide effective protection for the normal operation of production. However, the air compressor system often has some problems, and even seriously affect the production. In this paper, some snail
Q: How to choose the pressure and gas volume of the air compressor? Granklin Air Compressor Answer: The air volume and pressure of the air compressor are based on the gas volume and gas pressure of the equipment you use, and do a good job of upgrading the production line or reserving a part of the surplus gas volume in the future.
Water-lubricated single-screw air compressor is an oil-free air compressor series. Water is used as a lubricant to fundamentally solve the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has the advantages of simple and compact structure: low speed, low vibration and noise: low exhaust temperature: high thermal efficiency: stable and reliable performance, low specific power, etc.
