Introduction of 1. Granklin Water Lubricated Oil-free Screw Air Compressor
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, and low specific power. It is the development trend of new oil-free oil machines.
Its working principle is through the pressure difference generated by the compressor itself. During the compression process, lubricating water is continuously injected into the compression chamber and the bearing. The working principle is as follows:
the injected lubricating water can form a water film with a certain rigidity between the rotor, the star wheel and the casing, and the star wheel is directly driven by the main rotor. The lubricating water directly lubricates the graphite bearings at both ends of the star wheel.
2. oil-free water lubrication characteristics are as follows:
the injected lubricating water can achieve the airtight effect, which is better than the general dry screw compressor.
Lubricating water can absorb a large amount of compression heat, improve the compression efficiency, and avoid the possibility of friction or jamming due to different thermal expansion coefficients between the rotor, star wheel, and casing.
The lubricating water also reduces noise due to high frequency compression.
Granklin water lubricated screw air compressor uses purified water suitable for Chin standard, and the parts and components used are international standard grades 304 and 316 stainless steel.
Compressed Host Appearance
compressor host internal structure
the system uses pure water suitable for standard use, and the water circulates in the system all the time: and the system automatically changes water every 200 hours to ensure that the calcium content in the water is stable at the lowest value, and the operating temperature of the main engine is not higher than 50 degrees, so there is no risk of fouling.
After the air is compressed, its water content has reached saturation. The water content of compressed air is only related to temperature and has nothing to do with others. The temperature of compressed air produced by water lubrication unit is not higher than 50 degrees, and its water content is saturated at 50 degrees. As the exhaust temperature of other types of compressors is higher than 50 degrees, the water content of compressed air of water lubrication unit is lower than that of other types of compressor units.
3. Key Core Configurations
1. Original host
the host adopts a new generation of stainless steel water lubrication original host, the host adopts Sweden's highest quality SKF taper roller bearings, 24 hours of continuous and efficient low-temperature operation, the host service life of up to 100000 hours or more.
How much does it cost to maintain an air compressor? There are many things to refer to for the cost of one maintenance. For example, according to the degree of maintenance, air compressor maintenance itself can be divided into large maintenance, small maintenance and medium maintenance. And different air compressor brands,
Screw air compressor sometimes work for a long time, resulting in the phenomenon of high temperature, especially in the summer, when the temperature is too high fault often occurs, then the air compressor temperature is too high is how to return a responsibility? 1. Poor environmental ventilation and heat dissipation There are three main situations in which the surrounding environment of the air compressor affects heat dissipation: first, it is too close to wall-like obstacles; Second, there are other heat sources near the air compressor; third, the front door and side doors of the air compressor are open during operation, and the fan cannot form strong airflow.
It is not appropriate to make a brand comparison of air compressors. All air compressors are suitable for one's own. The following are some good manufacturers selling air compressors in China. Shanghai granklin, we produce water-lubricated oil-free screw air compressors, using a single screw water lubrication scheme to achieve no
As a professional equipment that gets along with laboratory personnel for a long time, the noise control requirements of the machine are very high. The procurement of laboratory air compressors needs to be oil-free and quiet to provide a good working environment for laboratory staff.
Energy conservation and environmental protection is always advocated by our country, and the R & D teams of manufacturing enterprises are also trying to develop energy-saving equipment. The screw air compressor, as one of the important gas equipment for production enterprises, will inevitably cause environmental problems in the process of use.
Screw air compressor exhaust temperature is high, why more and more manufacturers choose the water lubricated air compressor produced by Shanghai Grankering Group? Screw air compressor has a special PLC master controller, which can display the operating status, operating temperature, pressure, current, voltage and other common faults 1. high exhaust temperature.
View detailsWhat brand of air compressor is good? These questions are many buyers are more concerned about the problem. Under the epidemic, the market downturn, business difficulties, the company's decision makers in the procurement of air compressor equipment is also a different mindset, air pressure.
The full name of the air compressor is the air compressor; a machine designed according to the working principle that the rotation of the twin screw (also known as the yin and yang rotor) causes the gas to produce volume changes. It can inhale natural air and then complete the work through several internal processes. The final discharge meets the pressure
Medical oil-free air compressor refers to the kind of air compressor suitable for use in medical environmental health conditions. It requires precision, stronger reliability, environmental protection and quiet, fresh and clean compressed air, and the output gas can directly contact the human body. Displacement in less than 1m 3/min medical air compressor is mostly micro screw reciprocating air compressor, also known as oil-free air compressor, foreign also called micro screw swing air compressor.
medical air compressor choose water lubricated oil free air compressor medical air compression system it is the best "shanghai granklin oil free air compressor". The compressed air needed for survival cannot be interrupted for a moment. A continuous supply of mechanical ventilation is essential.
