OEM 7.5kw~250kw Oil-Free Water Lubrication Screw Air Compressor Screw Compressors

                     High Quality Screw Air compressor Our company specialize in making various kinds of compressors, such as:Diaphragm compressor,Piston compressor, screw Air compressor,Nitrogen generator,Oxygen generator ,Gas cylinder,etc. All products can be customized according to your parameters and other requirements.The screw compressor is a volume -type gas compression machine with a volume of work volume. The compression of the gas is achieved by changes in volume, and the change of the volume is to achieve a rotation movement in the case with a pair of rotor of the compressor.Basic structure of the screw air compressor: In the body of the compressor, a pair of intertwined spiral rotors are parallel. Usually, there is a rotor with convex teeth outside the ball, which is called yang rotor or yang screw. The rotor with concave teeth in the festival is called a pussy rotor or yin screw. Generally, the yang rotor is connected to the original motivation. Axial force. The cylindrical roller bearing at both ends of the rotor enables the rotor to achieve radial positioning and is underneath the radial force in the compressor. At both ends of the compressor body, a certain shape and size of the pores are opened respectively. One is used for inhalation, which is called the air intake; the other is used for exhaust, called the exhaust port.Customized is accepted , Pls provide the following information to us :1.Working Pressure : ____ Bar 2.Rated Power : _____ KW/HP Do you really choose the right Screw compressor?About Power Saving1. The annual electricity bill for purchasing a 37KW ordinary screw air compressor is 37KWx24hx365 days x1. 2 (electric fee) xO. 6 (loading) Power consumption is as high as 233.3366 million!

Two-stage integrated design, oil mist spray cooling is used between stages, which reduces the temperature of the air, and the compression process is close to the most energy-saving isothermal compression. In principle, two-stage compression saves 5%-8% of energy compared to single-machine compression ;2. It is suitable for the compression ratio matching of medium voltage, the leakage in the main engine is small, and the volumetric efficiency is high;3. The bearing adopts imported heavy-duty bearing, which makes the force of the rotor better; the two-stage rotors are driven by helical gears respectively, so that each stage of the rotor has the best linear speed;4. The third-generation asymmetric rotor technology, the tooth surface is processed by the German KAPP rotor grinder, creating a high-precision rotor, which is the first guarantee for the high efficiency and stability of the host.02.High efficiency permanent magnet synchronous motor1. IP54 protection grade, which is more stable and reliable than IP23 in harsh environment;2. Low temperature rise design, higher efficiency, and extended the service life of the motor;3. Use ceramic plated bearings to completely eliminate the influence of shaft current on bearings;4. It is made of rare earth permanent magnet materials, with large torque and small current during startup and operation;5. With reasonable magnetic field design and magnetic density distribution, the working frequency range of energy-saving motors is wider and the operating noise is low;6. Cooperating with the operation of the frequency converter, the frequency conversion soft start is realized, which avoids the strong mechanical impact of the machine and equipment when the motor is started at full pressure, and is conducive to protecting the mechanical equipment, reducing equipment maintenance and improving the reliability of the equipment.03. Special valve group1. Intake valve: It adopts a special normally closed butterfly valve for medium voltage, with a non-return function, stable operation, high precision of air volume control, built-in noise reduction design, low cavitation noise and long service life;2. Minimum pressure maintenance valve: special valve for medium voltage, high pressure resistance, high temperature resistance, accurate opening pressure, ensuring stable pressure in the barrel, ultra-fast return to seat, strong sealing, ensuring no backflow of gas, low pressure loss and high efficiency ;3. Temperature control valve: The unit is equipped with a mixed-flow temperature control valve to ensure that the unit is more convenient to start in a low temperature environment, and to ensure the oil supply of the unit at any time; by controlling the oil supply temperature of the main engine to en
