Simple introduction of screw air compressor without oil and water lubrication

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.
