How to correctly choose mute oil free compressor

 Due to mute oil free compressor adopts the oilless self-lubrication technology, so its core parts piston ring and bearing on the material requirement is very high, has struggled to get a good solution. With the progress of science and technology, some special wear-resistant materials used, the technical barrier is breakthrough. In less than 10 years, mute oil free compressor first born in Europe, because of its environmental protection and energy saving, low noise, without any oily substances, compressed air quality characteristics of pure and fresh, clean, safe and durable, popularized and applied widely in European and American countries. In 2002, Ryan, mechanical and electrical first silent air compressor imported from German production technology, won many national invention patents, for domestic mute oil free air compressor vendors would provide technical support, soon get promoted in China. Get rid of the imports have been awkward situation.

But, because of some domestic manufacturer technology is not standard, manufactured, produced the mute oil free compressor can not meet the international standards. 

So how to correctly choose mute oil free compressor?

First be clear what is mute oil free compressor, understand how it works.

The mute oil free compressor host adopt miniature reciprocating piston compressor, if not this type, you can be sure judgment does not belong to this kind of air compressor mute oil free air compressor, air quality could not reach the requirements of mute oil free compressor. Mute oil free compressor working principle of the host: single shaft drive compressor crankshaft rotates, through connecting rod drive, has the self-lubricating without adding any lubricant piston reciprocating motion, it consists of the inner wall of the cylinder, cylinder head and piston top surface of working volume will change periodically. Piston compressor piston from cylinder head start, the work within the cylinder volume increases gradually, at this time, the gas along the inlet pipe, pushed open the inlet valve into the cylinder, until the work gets to maximum volume, the inlet valve close; Reverse movement, piston compressor piston within the cylinder working volume shrinking, gas pressure, when pressure in the cylinder reaches and slightly higher than the exhaust pressure, exhaust valve.

The second is the mute oil free compressor have those parameters requirements, is correct and complete.

If technical parameter identification is complete, the right. According to international practice identifying parameter contains metric units and American units. For example, Ryan, mechanical and electrical parameter identification is very formal and accurate. Parameter identification is simple, because there is no related test equipment, can't do such a test of technology parameter, or some parameters can not meet the general standard of technology, therefore, when the choice it is recommended that you require manufacturers to provide detailed parameters, so that you make the right choice.

One final note is in line with the domestic industry standard, whether through national mandatory technical certification

Host whether to pass 3 c and industrial product license certification. Most manufacturers are now passed the certification of the CE of some foreign countries, such as, but because do not conform to the domestic industry standard, not through domestic compulsory certification, there may be a risk when using.
