Machine Details:
1.Intelligent Control
The intelligent controller of Chinese & English interface
supervises the operation of the compressor in real time. Its auto
warning protection function solves the problems of short-circuit,
missing phase, overload or else. If the abnormal condition exits
after checking the multi - point temperature and pressure, it will
alarm and shut down automatically. The equipment up-time and state
is recorded to remind the equipment to make a repair and
maintenance. According to the gas consumption, it can control the
discharge rate to distinct energy-saving effect.
2.Cooler
A huge design of cooler volume to discharge 35% margin. As a
result, a machine can operate at high temperature and avoid the
phenomenon of carbon deposit caused by the high temperature of the
compressor.
3.Electrical Components
Electrical components are made by the world famous brands Schneider
and Siemens which use silver contact to make it possible to operate
more than three million times and ensure the long-term safety.
4.Flex-mounted Precision Tube
To protect the pipelines from leaking and reduce the loss of oil
pipeline pressure.
5.Main Motor
It adopts triphase high performance motor made by a famous brand
with IP54 protection level, F insulation level and "SKF" heavy-duty
bearing. The transmission efficiency up to 95%, with good
thermostability and long lifetime.
6.Oil and gas separator
It adopts a huge oil and gas separator. After a three times' deep
bed filtration, the oil volume is less than 3ppm and the pressure
loss is only 0.02Mpa. With the reduction of oil mist exhaustion,
the running cost of downstream equipment is increasingly lessen.
7.Intake Valve
None is easily damaged with an ON-OFF regulation and the adjusting
range of tidal volume is 0 to 100%. It has small pressure loss and
long operating life. At present, it is the most effective and
reliable adjusting method of intake.
Advantages of Screw Air Compressor:
1. The screw air compressor works smoothly, with less vibration and lower noise than the piston machine.
2. Oil and gas separator: the filter material is adopted, with high efficiency, and the oil content in the air is lower than 2ppm.
3. Controller: The running operation and related data are displayed on the control panel, which is easy and convenient to operate.
4. The sprayed lubricating oil has the functions of sealing, cooling, noise reduction and lubrication.
5. Compared with the piston machine, it has less wearing parts and lower failure rate.
6. Cooling methods are generally divided into: water cooling and air cooling. The screw compressor has fewer parts and wearing parts, and the operation and maintenance costs are lower. Reliable operation and long life.
7. The cooperation between the male and female rotors and the rotor and the casing is set, so that the leakage of gas backflow is less, and there is no gap volume at the same time, so the efficiency is high.
8. High stability, high efficiency, small vibration, low noise, etc.
9. The cooling system is good. Using plate-fin structure and materials, the cooler is pressure-resistant, has high heat dissipation efficiency and good corrosion resistance.
10. Air filter: heavy-duty, multi-stage air filter, large working surface.
