Oil-free water lubrication air compressor is only water screw air compressor

The water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Thus, 100% oil-free clean compressed air is provided.

Product features:

1. High efficiency, high reliability, 100% pure oil-free compressed air, ideal isothermal compression, exhaust volume: 2.3-21.3m & sup3;/min.

2. Technical superiority of the electrical control system, caring and considerate maintenance instructions each unit adopts a microcomputer control system, with self-diagnosis and protection functions. Chinese LCD panel can display the actual operation of the unit. If the unit fails, the computer control system will respond accordingly according to different situations. The computer control system can prompt the user to replace parts and make necessary maintenance in time. The computer system of the unit has spare output, and the input terminal can realize interlocking control and remote control of multiple units. Guaranteed to work safely for you 24 hours a day. Granklin screw air compressor has mobile phone APP, which is convenient to monitor the use status of screw air compressor in time.

3. The water-lubricated air compressor head developed and produced by Grantklin Group has been verified for ten years to prove its advanced technical quality in air quality, energy saving and high reliability. Due to its perfect structure, it has a completely symmetrical balanced compression, which has smaller vibration and lower noise. ◇ Completely oil-free air quality water replaces oil, realizes the four major effects of lubrication, cooling, sealing and noise reduction, provides high-quality oil-free air of 100%, no pollution, no special treatment is required for discharged water, and meets the requirements of environmental protection. Due to the role of water, its compression is an ideal isothermal compression, and the air volume per unit horsepower is 15% higher than that of a general dry compressor.

In theory, when the air at 20 ℃ is compressed to 0.7Mpa in an adiabatic process, the discharged air will be higher than 250 ℃ because there is no cooling medium to participate in the compression. 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. 5. Meet the requirements of environmental protection air compressor and other accessories are the use of appropriate materials and processed to prevent rust, compression chamber gasket also use advanced materials such as ceramic, carbon fiber; high precision water filter high efficiency filter impurities, to ensure that the lubricating water to maintain clean water quality.

The temperature of the water-lubricated screw-free oil machine will drop to 40 degrees Celsius due to the injection of lubricating water into the compression chamber with cooling effect, achieving high-efficiency isothermal compression, while the temperature of the twin-screw dry-free oil machine will reach 250 degrees Celsius due to the lack of any medium for cooling in the compression chamber. This will consume a large part of the energy, because the higher the temperature of the air, the lower the compression efficiency, the operating temperature of the water-lubricated oil-free machine is not more than 50 degrees Celsius, which can greatly reduce power consumption, and the largest operating cost in the entire life cycle of the compressor is power consumption. General water-lubricated single-screw oil-free machine than the twin-screw dry oil-free 18-36% energy saving.
