Water lubricated oil-free single screw air compressor 7.5KW-315KW oil-free screw air compressor system and compressed air cleanliness (can be used for breathing pure air): innovative patented stainless steel water-gas separator barrel, and all stainless steel pipeline design, to avoid generation.
Screw air compressor system and clean compressed air (clean air for breathing):
Innovative patented stainless steel water-gas separating barrel and all stainless steel pipeline design can avoid rust corrosion while being cleaner and have longer service life.
There is no lubricant in the system and there is no risk of oil pollution. Compressed air cleaned by water is more environmentally friendly and clean.
The dew point of saturated compressed air is low and the water content is 25% less than that of ordinary dry screw air compressor without oil.
Energy-saving water-lubricated screw air compressor
1: Water-lubricated oil-free single screw compressor is energy-saving converter to control motor and main engine operation. Compared with compressor controlled by power frequency, energy saving is of practical significance. It is an economic operation mode to supply compressor power according to air demand. It saves about 15-30% of the electricity cost, and can recover the invested funds from half a year to one year. High-speed water-lubricated oil-free variable-frequency single screw compressor, according to the customer's gas consumption, achieves speed regulation, and maintains a good operating efficiency between the output gas volume and system consumption. To achieve energy-saving effect. Because of its strong automatic adjustment ability, it can quickly respond to the change of system pressure and maintain good operation efficiency. Compared with ordinary compressor, the advantages of frequency conversion compressor are not only clear benefit of saving power, but also stable exhaust pressure, improving motor power factor, effectively reducing starting power supply, and prolonging compressor service life.
2: The principle of frequency conversion and energy saving system of Water-lubricated variable-frequency oil-free single screw air compressor is as follows: Comparing the pressure value of pipeline network measured by pressure transmitter with the set value of pressure, the deviation is obtained.
The PiD regulator calculates the frequency of the converter acting on the asynchronous motor. The corresponding frequency and amplitude AC output by the converter obtains the corresponding speed on the motor. Then the compressor output corresponding compressed air to the storage tank, so that the pressure changes until the pipe network pressure is the same as the given pressure value, which has obvious energy-saving effect.
3: Water-lubricated oil-free single screw air compressor also has the following advantages; generally it does not operate in high-speed areas, prolonging the life of motor and main engine bearings. The pressure at the outlet of the gas storage tank can be kept stable in the operation state of frequency conversion, and the pressure fluctuation range can not be too large (+0.2 bar). Frequency converter starting compressor from OHz, its starting acceleration time can be adjusted, so as to reduce the impact of starting on compressor's electrical and mechanical components, enhance the reliability of the system, and prolong the service life of the compressor. The motor runs slowly, which effectively reduces the noise and vibration of the air compressor. Noise decreases by about 3 to 7 decibels compared with the original system. Frequency conversion control can reduce the current fluctuation during unit start-up, which will affect the power consumption of power grid and other equipment. Frequency converter can effectively reduce the peak value of starting current to a low level. It does not affect the power consumption of power grids and other equipment.
The main thing is low operating costs. Its energy cost is reduced by about 44.3%, and its benefits are considerable.
