[circle in the air Yue science and technology] pneumatics machine is main manufacturing motive force supplies equipment, scientific type selecting is bought, will tell to the user, very important. This period roll out pneumatics machine type selecting 6 big notes, for you science is energy-saving, provide mighty power for production.
One, consideration exhaust pressure and capacity
The capacity look that the tolerance that selects pneumatics engine wants and wants matchs, leave the surplus that has 10% at least, if use gas end and pneumatics machine space further, or the near future has a few budgets that add new pneumatic tool, can increase surplus to 20% .
If use tolerance big and pneumatics aircraft capacity is small, cannot drive uses gas tool. If use tolerance small and capacity is large, can let pneumatics machine increase add uninstall a frequency, long-term low frequency runs empty perhaps press, create waste of the sources of energy.
When pneumatics machine type selecting, formula is:
Air needs dosage = will be all tool + machine equipment + wastage of relevant flow air + leak + wear away + future uses gas + use coefficient (1.1 to 1.2) .
Additional, consider a height even when choosing capacity dosage and normally dosage reachs trough dosage, it is firm that workshop section uses tolerance finalize the design or wave motion, for example: AThe pressure when the workshop is produced and keep balance basically with tolerance, empty press needs to often leave, labour frequency series or permanent magnetism series all but;B workshop fluctuates with tolerance and pressure opposite bigger, part of the equipment that use gas often leaves, choose permanent magnetism series to suit more, so when many workshops are used with tolerance inhomogenous, criterion the pneumatics machine paralell connection with many lesser capacity acquires larger capacity, as increase with tolerance and one by one switchs on the mobile phone, with managing the sources of energy.
Pressure of pneumatics machine exhaust is the aeriform pressure that points to final eduction compressor (gauge pressure) , the unit is for: MPa. Inside course of study commonly used ” kilogram ” as pressure unit, 1 kilogram of =0.1Mpa.
The force of platoon atmospheric pressure of the mark on pneumatics machine nameplate calls rated exhaust pressure, when type selecting, cannot pay close attention to a baric force of nameplate only, and should undertake assessment to the whole system that use gas, consideration pressing falls reach control damage, will tell commonly:
The final user of actuating pressure = that decides finally + end class filters + pipeline system + grit filters + drier + compressor adjustment extent.
The use pressure that lists all sorts of machine are planted still answers when type selecting, differ like use pressure too much, need the empty press that purchases different pressure, cannot reduce pressure to use, in order to raise expenditure pay.
2, consideration can effect and than power
Of pneumatics machine can effect grade is evaluated through comparing power to be worth, namely pneumatics engine power / a tolerance of pneumatics machine.
One class can effect: ? Wan of which Long of of Sao of flatter of a kind of net used for fishing or for dredging up river sludge of of sword of of of Ran of anxious mace does turn over?
2 class can effect: ? Does Ran administer flatter?
3 class can effect: ? Nocturnal humorous > А of benzyl of sodium arrogant ?
3, the consideration uses smell situation and condition
Ventilated condition is good, have installation space to choose wind cold machine to suit; to use more when tolerance is big, the circumstance with better water quality, choice water-cooling machine suits more.

4, the consideration reduces air quality
Reduce air quality pure spend commonly used standard to be GB/T13277.1-2008, the machine that do not have oil is commonly used IS08573-1:2010 international mark
Accurate.
Machine of pneumatics of fuel injection screw produces compress air, contain miniature oil grain content, water, reach content of grain of small this world, wait for an aftertreatment through configuring gas tank, cold dry machine, accurate filter implement make compress air to purify, the part measures tall situation with temperament, can configure blot machine to filter further.
Of machine of the pneumatics that do not have oil compress air, can achieve very high air quality, nurture heart compresses air to reach the level of CLASS 0 grade of ISO 8573 standard entirely without what oily series produces.
The compression of need air quality, the demand of facilities of the product that needs to see production, production and pneumatic tool and calm. Compress air not to amount to mark, light bring about commodity quality to drop, weigh an attaint to produce equipment, but not be pure degree it is good to jump over Gao Yue, excessive and pure compression air, it is addition equipment purchases cost, 2 was to increase electric power waste.
5, the security that considers pneumatics accident travel
Pneumatics machine is the machine that a kind of belt pressing works, the gas tank of 1 cubic above belongs to special type to produce equipment, the security that its run should be put in the first place.
When pneumatics machine type selecting, the user is sure to check pneumatics aircraft manufacturer produces aptitude, assure the product quality of pneumatics machine.
6, the after service that considers a manufacturer
Protect character period the care and maintenance inside is in charge of by manufacturer or service business directly, but use process still has certain cannot unknown factor, when pneumatics machine has trouble, after service is seasonable, it is professional that dimension maintains a level, it is the problem that the user is sure to care.
Machine of more screw pneumatics, problem of engine of centrifugal type pneumatics, seek advice please without science and technology of Xi Xiang Yue. # of machine of pneumatics of screw of # of # pneumatics machine
