Why Choose Lingyu 4 in 1 Screw Air Compressor With Dryer
(1) Output High Quality Compressed Air
Firstly, this integrated air compressor has 4-stage high-precision filters. Besides, it’s also with a high-performance refrigerated dryer. Therefore, the water removal efficiency is far more than 99%. The particle content is ≤0.01um. Oil content as low as 0.003 ppm. Moreover, the pressure dew point is as low as 2-10℃.
So it can remove tiny oil and water molecules. Then it produces high-quality dry and clean air. This is essential for our laser cutting production.
(2) Compact Structure Can Save Space
Secondly, the compact compressor adopts an integrated design. It brings all the parts together. That is a screw compressor, refrigerated dryer, air tank, and filters.
It’s a compact design. Thus, this industrial air compressor machine can save space costs. Besides, there is no need to install pipes. It realizes plug and play.
(3) 2 Years Warranty High Quality Compressor Airend
Our 4 in 1 air compressor uses the famous Hanbell brand airend. The airend is with Sweden’s original SKF bearings. Moreover, there is an internal temperature control system. Copper pipes, so it has high pressure and corrosion resistance.
In addition, we use the permanent magnet motor. High-performance RuFeB permanent magnets do not lose magnetism at 200°C. Besides, the energy saving of our screw compressor with dryer can be up to 30%.
(4) Intelligent Computer Control System
The air compressor rotary screw is easy to use. It realizes one-button control for the compact compressor. In addition, it has with alarm display. Moreover, we can switch Chinese/English freely. And it can intelligently monitor the usage time of filters and lubricating oil. Besides, there is a remote control function.
(5) Air Tank Can Ensure Stable Pressure
The air receiver reduces pressure fluctuations. So reduce the start and stop of industrial air compressor machines. In addition, it can also remove a part of water. So it can reduce the load of refrigerated dryers.
(6) Use High Efficiency Oil Filter, Air Filter And Separator
The air filter has a large filtration area. It has higher precision and longer life. In addition, it can pressure loss in the screw compressor with dryer.
The oil separator adopts a special design. It is composed of a gathering separation core and an oil return device. The service life is up to 6,000 hours. The oil filter is designed with a low-pressure drop. The service life can reach 4000 hours. High filtration precision can effectively protect the bearings and rotors of airend.
Why Does The Laser Industry Use The Integrated Compact Compressor?
Auxiliary gas is an indispensable substance for laser cutting. Compressed air is the most commonly used. Because compressed air is much cheaper than oxygen and nitrogen. In addition, it can blow away metal slag. It also prevents dust from clogging the laser nozzle.
At first, the laser cutting used low power. But it keeps developing to high power. Likewise, the pressure of the compact compressor is constantly increasing. At first, it was 8 bar. Later it increased to 13 bar. And now we usually use 16 bars. Of course, it is still developing towards 20~30bar.
The quality of compressed air has a direct impact on laser cutting. So we need to use a rotary screw compressor with dryer. Laser cutting generally requires multi-stage filtration. In order to better protect the service life of the laser cutter. If don’t clean water mist and oil, they will be sprayed on the protective mirror surface. As a result, it will severely affect the transmission of the laser beam. So it will scatter focus. Finally, the cutting efficiency is reduced. Besides, it is also possible to burn out the laser head.
Our 4-in-1 air compressor can effectively remove water and oil. Because the refrigerated dryer can remove 99% of the moisture. Moreover, the filters can also remove water, dust, and oil. So compact compressor ensures high-quality compressed air.
How Does Rotary Screw Compressor With Dryer Work?
The rotor of the PM motor directly drives the compact compressor. It is mounted on the output shaft. Firstly, the air goes through the air filter. After filtering, it passes via the intake control valve. And then enter the compressor intake chamber. The airend screw groove compresses air. Afterward, it is discharged from the air outlet. Next, it enters the oil separator. Oil and air separation takes place here. After separation, the oil content is very small.
Then compressed air passes via the minimum pressure valve and the aftercooler. Finally goes into the air tank. The air receiver can stabilize pressure. Besides, it can reduce temperature. Also, remove some moisture.
Hereafter, the air enters the air-water separator. It will separate out many water. Then air goes to the evaporator of the refrigerated dryer. Deep cooling takes place here. It can turn gaseous water into liquid water. Besides, liquid water will be drained. Finally, the air goes back to the heat exchanger of of dryer. It will heat up here.
In addition, the precision filters can remove dust, oil, and water. The separated lubricating oil will settle to the bottom of the oil-air separator. It is cooled by an oil cooler. Finally, it will return to the working chamber of the screw compressor with dryer. So it starts recycling.
