Pneumatics machine type selecting ” 3 big parameter ” what be?

Pneumatics machine has 3 essential factor commonly: Pressure, discharge, power. Normally manufacturer knows to be able to help user type selecting secondly. What correlation is there between them so?

1. the actuating pressure that what is pneumatics machine? 　　

The actuating pressure of pneumatics machine, domestic user often calls exhaust pressure. It is the pressure that points to gas of pneumatics machine eduction. Commonly used actuating pressure unit is: Bar or Mpa, conversion means is: 1 Bar = 0.1 Mpa. A lot of users call pressure unit normally Kg, conversion method is: 1 Bar = 1 Kg. 　

2. the cubage discharge that what is pneumatics machine? 　　

Cubage discharge, domestic user often weighs capacity or nameplate discharge. It is to show the exhaust pressure that asks in place falls, the aeriform cubage convert of the eduction inside time of pneumatics airplane unit arrives to be measured into what enrage condition. Cubage discharge unit is: M3/min or L/ Min, general, commonly used discharge unit is: M3/min. Its conversion means is: 1m3= 1000L. 　　

The power of pneumatics machine, it is the nameplate power that points to the drive electric machinery that matchs or diesel engine.

The unit of power is: KW or HP. Its conversion means is: 1.333HP of 1KW ≈ . 　　

① is run-of-mill, the power of pneumatics machine is the power of drive electric machinery that shows place matchs; 　　

The unit of ② power is: KW (kilowatt) or HP (be equal to / horsepower) , 1.333HP of 1KW ≈ . 　

Next, in light of us 3 person the relation between: In power changeless circumstance falls, when rotate speed happening changes, cubage discharge and actuating pressure also produce change accordingly; For example: The empty press of a 22KW, affirmatory when make actuating pressure is 7bar, according to rotate speed of computation of curve of compressor mainframe technology, when capacity should decide for 3.8 M3/min; actuating pressure is 8bar, rotate speed must be reduced (otherwise excess load of drive report opportunity) , at this moment, because,capacity is 3.6 M3/min; , rotate speed was reduced, exhaust also decreased accordingly, the rest may be deduced by analogy.
