Technical advantages of water-lubricated oil-free screw air compressor

The water-lubricated oil-free screw air compressor is mainly composed of a multi-head screw, two star wheels and the body. Compact structure, small size and light weight. The screw rotates into one with multiple suction, compression, and exhaust processes. When the screw runs at high speed, the flow pulsation is small and the exhaust volume is large. Due to the symmetrical installation of the star wheel, the force of the screw is completely balanced, the vibration is small, and the noise is more than 10Φ lower than that of the twin screw type. Due to the balanced force of the single screw, the highest pressure of the first-level pressing can be greater than that of the twin screw: the single screw is more energy-saving than the twin screw, the bearing size is not as restricted as the twin screw type, and the life is longer. It is completely balanced and can work in a small working gap, with small leakage and high volume efficiency.

Characteristics of water-lubricated oil-free screw air compressor and dry oil-free screw air compressor

Theoretically, when a 20 ° C empty air is compressed to 0.7Pa in an adiabatic process; if no cooling medium is involved in the compression, the air discharged will be higher than 2 ° C. When lubricating water with excellent cooling efficiency is injected into the compression chamber, the exhaust temperature will be Will drop to 40 ℃, to achieve high efficiency isothermal pressure. Therefore, the water-lubricated oil-free compressor is an energy-saving product, especially compared with the dry oil-free screw compressor.

Core technology of water-lubricated oil-free screw machine

Using patented screw meshing line technology and unique processing special machining methods to improve the meshing precision of the star wheel and the screw, overcome the low viscosity characteristics of water, and achieve isothermal compression; use hydrophilic FE star wheel material; adopt advanced mechanical seal technology , To ensure that the compressed air is 100% oil-free; after a long-term durability test, the bearing can run for 50,000 hours or longer; the main body metal is made of special copper alloy material, which has strong corrosion resistance and high stability characteristics; the entire system design has the same Corrosion resistance.

With soft start function

The start of power frequency air compressor is star / delta mode, the starting current is 5 ~ 7 times of the small rated, the start of the variable frequency air compressor is the frequency lowering mode, the starting current is within 12 times of the rated. The frequency conversion starting method not only affects the electricity and the grid, but also significantly reduces the impact on the mechanical and electrical system of the air compressor wooden body.

Broaden the voltage range

The frequency converter adopts modulation technology, which can make the motor output enough torque when the voltage of the grid input is slightly lower. When the voltage of the grid input is slightly higher, it will not cause the motor current to be too large.

Save energy

Generally, the gas consumption will change at any time, and the power frequency air compressor will inevitably be frequently loaded and unloaded. During unloading, the motor consumes reactive power: the working pressure setting of the power frequency air compressor is at least 0.2Mpa higher than the working pressure of the gas equipment. In order to ensure that the discharge pressure of the air compressor during unloading can meet the requirements of the gas consumption equipment, according to the calculation: for this 0.2Mpa pressure, the air compressor consumes 20% more electricity, and the variable frequency air compressor is not in these pros and cons

Noise reduction

The electric frequency of the inverter air compressor motor is less than the power frequency and has a soft start function, and the operating noise of the air compressor is significantly reduced
