Pneumatics machine sort is various, type diversity, small the pump that uses to car, tractor, arrive greatly the cut into a mountain, large empty press that digs mine to use, value also is differ to hundred thousands of yuan by thousands of yuan. How to undertake to pneumatics machine type selecting is mixed purchase, involve not only how reasonable setting budget, the cost of the requirement that also should run considering follow-up production and care and maintenance. Want to choose pair of empty press so, must want to understand these problems first.

Machine of general use pneumatics presses national level to set, exhaust pressure is 0.7MPa. If prep above or under this pressure, belong to namely nonstandard machine of special type pneumatics. If user place is used compressor is more than 0.8MPa, want commonly special make, cannot adopt forcibly the method of pressure boost, lest cause an accident. Additional, consider a height even when choosing capacity dosage and normally dosage reachs trough dosage. If trough dosage is bigger, and dosage and height dosage are not normally big, abroad normally method is the pneumatics machine paralell connection with lesser capacity acquires larger capacity, as increase with tolerance and one by one switchs on the mobile phone, such not only have profit to electrified wire netting, and can managing the sources of energy.
2. uses gas occasion
If use gas field narrow (marine, car uses) , should choose vertical; If use smell situation to have the change of Sunday run (more than 500 meters of) , should consider movable type; If use an occasion cannot power supply, should choose form of diesel engine drive; If make do not have tap water with the circumstance, must choose wind cold form. In wind cold, water-cooling cools two kinds on means, the user often has wrong knowledge, think water-cooling is good, actually otherwise, wind is cold have respective actor drawback with water-cooling, the user should decide according to effective demand.
3. uses temperamental amount
General pneumatics opportunity arises compress air to all contain certain amount lubricating oil, have the water of certain amount, some circumstances are to ban oil and ban water, at this moment not only want to notice to compressor type selecting, want to add auxiliary unit when necessary. Settlement way: It is to choose without lubricant compressor. In air cylinder of this kind of compressor can accomplish basically 1005 not oiliness. 2 it is will empty press (no matter which are planted) increase one level again or 2 class purifying device or desiccator.
4. runs safety
Pneumatics machine is the machine that a kind of belt pressing works, the companion when the job has temperature rise and pressure, the security that its run should be put in the first place. The country executes standardization to the production of compressor ” two card ” system, namely compressor production licence and licence of pressure vessel production (gas tank) . Accordingly, when product of compressor of choose and buy, should examine strictly ” two card ” . The product warranty system that has card manufacturer normally is perfect, won’t appear big quality question, although go out,show a few issues, also can be in charge of 3 packets by manufacturer.
