                     High Quality Screw Air compressor 

 

Our company specialize in making various kinds of compressorssuch 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.

About Power Saving
1. 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!


Power saving after switching to permanent magnet variable frequency screw air compressor:
23. 3366x30% save electric fee 7. 00.98 million!

Advantages of screw air compressor :
01.
Advanced Medium Voltage Dual Stage Mainframe
1. 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 motor
1. 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 group
1. 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 ensure that the unit is in the best performance state;
4. Oil cut-off valve: special normally closed valve for medium voltage, controlled by the exhaust pressure of the machine head. When starting up, the valve opens quickly to ensure that the compressor is lubricated and warmed up as soon as possible; when shutting down, the valve prevents oil from being ejected from the intake end.

4.Advanced and reliable electric control system
1. Large-size color LCD touch screen, with good man-machine communication interface, touch screen with anti-mistouch and sleep function;
2. It adopts double frequency conversion system, which is more energy-saving. The frequency converter and the motor are perfectly matched, and the low frequency and high torque can output 180% of the rated torque;
3. According to the characteristics of medium voltage, a special program is developed, with multiple pressure sensors and multiple temperature sensors, which can comprehensively detect the operating status of the unit, and automatically control the machine status without special care;
4. Configure the Internet of Things, you can check the operating status of the unit on the mobile phone;
5. Independent air duct design, suitable for various working conditions.
5.
Silent centrifugal fan
1. Adopt centrifugal fan, brand-new separate radial cooling fan design, with special cooler, better cooling effect and more energy saving;
2. Compared with axial flow fans, centrifugal fans have higher wind pressure and lower noise;
3. Using variable frequency fan control, the oil temperature is constant, prolonging the service life of lubricating oil;
4. Due to the high wind pressure, the cooler and the filter are less likely to be blocked.
6..High quality triple filter

1. The filtration area of the air filter exceeds 150% of the normal requirement, the inlet pressure loss is low, and the energy efficiency is good;2. The oil filter adopts a full-flow built-in pressure-bearing oil filter suitable for medium voltage conditions. The rated processing capacity of the oil filter is 1.3 times the circulating oil volume. The imported filter material and the design scheme of large margin are selected, which has high filtration precision and good durability.
3. The oil is divided into special customized oil, which is designed and developed for medium-pressure working conditions, with wide applicable pressure range, good separation effect and low operating pressure loss; imported glass fiber material is selected;
4. The design of the three filter positions is reasonable, the maintenance is convenient, and the downtime is reduced.
High quality and efficient coupling

1. The coupling is a torsional elastic coupling with a failure protection function, which can effectively damp and reduce the vibration and impact generated during operation;
2. The elastic body is only under pressure and can bear a larger load, and the drum-shaped teeth of the elastic body can avoid stress concentration.
