After years of accumulation and precipitation of Hannos oil-free screw technology, 7.5KW to 132KW new oil-free screws have been officially produced in batch. Today, with two oil-free models of 11KW15kg pressure laser and 22KW8kg normal pressure, we came to Dongguan Houjie Modern Exhibition Center South China International Air Compressor Exhibition again. The light green coat with black columns, the bright appearance immediately attracted many professionals to visit, see the picture:

Can external color and external details determine everything? If you think so, you are very wrong. Now it's time for the editor to give you a proper introduction:

1. Autonomous host:

The water-lubricated oil-free air compressor must first depend on the machine head: it is made of 304&316 stainless steel, which is made of the most advanced imported high-precision machine tool, and the three-dimensional detection error is about 1 wire. What is the concept? Let me tell you: the diameter of our boys' hair is 6, and the error of one-sixth of the hair ensures the perpendicularity and concentricity of the host machine. The high-speed operation for a long time will not wear the star wheel and the screw groove. The star wheel piece is basically fully meshed with the screw groove by arc machining, and the movement gap between them is sealed by multi-point injection of pure water. The internal air tightness and lubricity are comparable to that of lubricating oil, the energy efficiency can reach the energy-saving standard of oil engine, and the durability can be guaranteed for five years.

2. Cooling system:

Two types of water cooling and air cooling are adopted. The water cooling adopts stainless steel plate heat exchanger, which is characterized by fast and efficient heat exchange. The air cooler adopts copper tubular radiator, and the operating temperature is controlled within 50 ℃. The sample adopts the inner rotor axial flow fan, which is durable and practical. At this time, some people may ask why not use the centrifugal fan? The centrifugal fan is characterized by high wind pressure and power, which is not conducive to energy saving and high cost. Under what circumstances? Generally, the centrifugal fan must be selected when the area of the copper radiator is small, the fin is too dense and the thickness is relatively thick. Hannos oil-free heat dissipation design has a large and thin heat exchange area, so it is not necessary to use centrifugal fans. Of course, if you think the outlet temperature should be lower, you can also customize it.

3. Moisture separation system:

The water and gas separation barrel is made of 304 stainless steel, with built-in mechanical separation device, which can never be replaced. The water removal rate reaches 99%, which is safe and without pressure loss, and improves the energy efficiency of the whole machine.

4. Drive and control system:

The motor adopts the most famous brand of permanent magnet motor, with the efficiency of 96%. The control also uses the domestic famous brand control panel and permanent magnet frequency converter, which makes the control flexible and durable. If it is equipped with remote box and software, the machine operation can be monitored remotely, which really forms Hannos Internet plus.
