Medium pressure water lubricated oil-free air compressor

The medium pressure oil-free screw machine has the advantages of compact structure, high working efficiency, low noise, low vibration, convenient maintenance, low operating cost and good air quality. At the same time, this series of machines adopts microcomputer control system, and the whole machine is equipped with multiple protection functions such as pressure, temperature and overload.

The screw host with high volumetric efficiency is adopted, which has low specific power and is more efficient and energy-saving than twin-screw anhydrous compressors.
The main engine is lubricated by water, the compressed air is not polluted, and the waste lubricating oil is avoided at the same time, which meets the requirements of environmental protection.
It is quieter than the oil-injected screw compressor, and the noise is 4-5db(A) lower than that of the oil-injected screw compressor of the same specification.
Since no lubricating oil is used, there is no need to exchange waste oil, oil filter, oil separator, etc., and the operating cost is lower.
The motor is a special special motor, SKF bearing, insulation class F, protection class IP54 to ensure trouble-free operation. The efficiency is 3-5% higher than similar products.

High-precision rotor: The rotor is made of durable corrosion-resistant stainless steel, and the tooth surface is processed by five-link high-precision rotary teeth. Secondary enveloping helical processing, the surface is like a mirror surface, reducing internal leakage, avoiding thermal expansion during operation, ensuring proper clearance between mirror surfaces, and generating 5-10% higher air volume. Verify the existence of dynamic pressure water film, never worry about corrosion.
Stainless steel alloy shell The durable shell is forged as a whole without welding. The strength and hardness are far beyond the welding technology. The speed of 2970 rpm will generate a certain pressure. Rotary teeth of the technology, when the compressor is running, the rotor has zero contact with the casing, no wear, and long life. The suction port and the air outlet are respectively located on the upper and lower symmetrical planes, and no negative pressure is generated in the axial direction, thereby prolonging the service life of the bearing. All twin-screw machines run with oil, the chambers are sealed and separated, and we seal and lubricate with water.
Clean, zero pollution oil-free compressed air, its zero emission and zero pollution treatment method can effectively protect the environment. Water - Lubrication, Sealing, Cooling Ideal for isothermal compression (large displacement) Cryogenic compression (less than 40°C) No need for intercoolers and aftercoolers
No oil is used, no oil-free filters and oil-gas separators are required for oil-free treatment, which reduces industrial waste, avoids oil and gas, and causes fire hazards; reduces pressure loss, saves energy and is environmentally friendly, and is a green product advocated in the era of energy crisis. The condensed water is oil-free and requires no special treatment.
