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.
Air compressor mentioned earlier, is the air compressor, the main job is to compress gas, air compressor is divided into many kinds, let's take a look at it in the end what classification,
Factory air compressor air pressure setting standards and industry application specifications In the field of industrial production, air compressor as the core power equipment, its air pressure setting should strictly follow the process requirements and safety specifications. Industry practice has proven that the air pressure configuration of the factory air compressor system should follow the following techniques.
Air compressor type variety, wide range of uses, and different types of air compressor, the lubrication requirements vary greatly. In the air compressor parts, the lubricating oil plays a role in preventing wear, sealing, and cooling, minimizing the influence of air on the viscosity of the lubricating oil and the reaction between additives and air, so as
Screw air compressor operating procedures: 1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor. 2. operators must undergo technical training and safety training and pass the examination.
This depends on the brand of the air compressor, and whether it is imported or made in China. Relatively speaking, the price of the domestic 10 cubic screw air compressor is definitely a little cheaper than the imported one. 10 cubic screw air compressor price is not
Purchasing air compressors in Taiwan, especially screw air compressors, can choose Shanghai Granklin Group in mainland China. A focus on water-lubricated air compressor enterprises, products to achieve oil-free, stable gas supply, in the domestic air compressor industry belongs to the high-end industry.
View detailsWhy should ordinary oil injection screw air compressor be replaced by water lubricated air compressor? We first understand what is the air oil content. Compressed air as the second largest power energy after electricity, its application in all walks of life. Different industries have different requirements for the quality indicators of various pollutants in compressed air. Some industries have higher requirements for the quality of compressed air, and there is no lack of demand for oil-free compressed air.
View detailsThe water lubricated air compressor produced by Shanghai granklin group belongs to screw type in the air compressor category. Screw type air compressor is divided into twin screw and single screw. The water lubricated air compressor uses single screw compression. Under the condition of the same power consumption, the single screw gas production is more sufficient. Air compressors are classified according to the principle. Air compressors can be divided into two categories: rate type and capacity type. The gas machine is divided into: rate type; Capacity type; Capacity type is divided into tube type and reciprocating type; Tube type: rotor type; Screw type; Slide built-in type.
View detailsGranklin Group is a manufacturer specializing in the production of water-lubricated air compressors. The water-lubricated air compressors we sell are very suitable for medical equipment and hospital oxygen supply. Water lubricated oil-free air compressors are often used in hospitals, laboratories and other industries where the environment is quiet and the quality of the gas source is high.
View detailsThe general classification of air compressors has the following methods: 1. According to the gas transmission volume, the so-called gas transmission volume refers to the volume of each minute of gas discharged by the air compressor when it is working, which is converted into the suction state. The small exhaust volume is less than 10 cubic meters/minute, the medium volume is 10-100 cubic meters/minute, and the large volume is large.
