In pharmacy industry, need of general pharmaceutical factory undertakes be controllinged strictly to compressing the water in air and oil. And the oil in compressing air still basically produces the empty press that compresses air place to use to bring. Below strict requirement, without oil model pneumatics machine becomes more and more welcome. To this, the article will introduce a few kinds of market to go up not to have model of oily pneumatics engine commonly to everybody, include not to have type of machine of oily piston pneumatics, vortex not to have oily machine, dry type not to have oily machine, water to lubricate without oily machine, centrifugal type the machine that do not have oil.

Without machine of oily piston pneumatics

Machine of pneumatics of the piston that do not have oil is to use colophony material to lubricate, the gas of eduction not oiliness, as we have learned, it is to have the oil-lubricated opportunity that do not have oil commonly on Chinese market, in recent years new developed a kind to be on base of engine of pneumatics of the former piston that do not have oil chance of improved devoid oily pneumatics, the equipment after improving used block to heat up a piston, make bearing grease suffers high temperature to conduct with radiation prediction of a person’s luck in a given year no longer.

Of this kind of type having dominant position of oil pneumatics plane is relatively cheap. But noise is big, maintain frequent, cost is high, gas damage is big. Basically apply at unit of clinic of small small-sized private and the enterprise that just started, small-sized dentistry, scientific research to wait at present.

Vortex type does not have oily machine

The working principle that vortex type does not have oily machine is, move eddy the heart makes voluminous static Guo Panzhong the plane with very small radius is rotational, formation working antrum expands accordingly or narrow, what realize gas from this is inspiratory, compress and exhaust process.

The advantage of this kind of equipment is Jing Yin the effect is good, low-cost, and have brand effect, but because it is small capacity type, specific power consumption is big, lead plane life is brief. Be in at present unit of clinic of hospital, dentistry, scientific research, presswork, the circumstance such as spray industry has the market.

Centrifugal type does not have oily machine

Centrifugal type does not have oily machine is the gas of unifoliate wheel pair that runs through high speed does work make aeriform pressure and speed elevatory, the carriage of the gas that finish, aeriform edge radial has shed the compressor of impeller.

Current, centrifugal type is using broad-minded biology to ferment without oily machine, separate an industry for nothing, the industry of chemical industry, oil, natural gas, refrigeration market with having particular.

Dry type does not have oily machine

Doing type not to have the working principle of oily machine is, the gas of double leaf wheel pair that runs through high speed does work make aeriform pressure and speed elevatory, the carriage of the gas that finish.

The market of this kind of machine that do not have oil is had rate is high, brand effect, the technology is stable. Nevertheless blemish is to purchase cost tall, specific power consumption is big, maintain cost is high, put in oily risk. Apply to the need such as medicine, food, chemical industry, electron to reduce the trade of pneumatics completely at present.

Water is lubricant the machine that do not have oil

Water is lubricant the machine that do not have oil is to use pure water to regard as compress medium, astral annulus piece, the roll that compresses the housing, sealed space that forms with screw snail chamfer to pass screw, cubage is reduced, and form pair of airy to compress.

Its advantage is a gender valence comparing is tall, the operation is simple, moving cost is low, maintain simple. Nevertheless water lubricates to be had without the market of oily machine little, the trademark is well-known degree low. The industry that waits for need to compress pneumatics completely in medicine, food, chemical industry, electron at present applies somewhat.

The user can handle demand according to what differ, combine the condition of the choose and buy, the selection gives chance of equal the pneumatics that do not have oil. Notable nevertheless is, when the user is choosing a kind of model, because congener product is more on the market, the user still needs sharpen one’s eyes, “ goods compares 3 ” , choose normal manufacturer, the quality that lets a product and after service have safeguard, such in case equipment is unavailable after occurrence breakdown the circumstance of the help.
