Machine of pneumatics of air compressor abbreviation, it is the most commonly used air motive force in a kind of industrial and mining enterprises supplies equipment. Normally, pneumatics aircraft component is machine of screw type pneumatics, piston pneumatics machine to wait. How do a lot of people work not to understand to pneumatics machine, this article arranged pneumatics mechanic to make a principle relevant content, hope to be able to be helped somewhat to you. ?
? 1, inspiratory process: ?
The side taking energy of life of screw type is inspiratory mouth, must design so that make compress the room is OK and sufficient inspiratory, and screw type compressor is not had into gas and exhaust valve group, the open that relies on one control valve only into gas, shut adjust, when rotor is rotational, advocate when the space of roller seating space of deputy rotor is turning to wall of the end that take energy of life to start to talk, its space is the largest, right now the space of roller seating space of rotor and the free air of the mouth that take energy of life are interlinked, because of the air in the roller seating space when exhaust by total number eduction, when exhaust ends, roller seating space is in vacuum condition therefore, when turning to the mouth that take energy of life, outside air namely by inspiratory, edge axial is flowed into advocate inside the roller seating space of deputy rotor. When air fills whole roller seating space, the end panel of the side that take energy of life of rotor turns the opening taking energy of life that left housing, the air between roller seating space is closed namely, above is, [Intake process] . ?
2, close reach carry a process: ?
Advocate deputy two rotor are when inspiratory end, its advocate peak of deputy rotor tine can be shut with housing, right now air is shut inside roller seating space no longer outflow, namely [close process] . Two rotor continue to turn, its age peak and roller seating space are in inspiratory end be identical, be identical face carries shift to exhaust gradually, this namely [carry process] . ?
?
3, compress reach injection process: ?
In carrying a process, face of clench the teeth carries shift to exhaust gradually, i.e. is reduced gradually between the roller seating space between face of clench the teeth and vent, the gas inside roller seating space is compressed gradually, pressure increases, this namely [compress process] . And reduce the effect that at the same time lube also differs because of pressure and gush is entered compress indoor mix with room gas.
4, exhaust process: ?
When the end panel of clench the teeth when rotor turns to be interlinked with housing exhaust, (the pressure that reduces gas right now is highest) the gas that is compressed begins eduction, till age the scale of clench the teeth of peak and roller seating space moves,come exhaust end panel, right now space of this roller seating space is face of two rotor clench the teeth and housing vent 0, finish namely (exhaust process) , at the same time here face of rotor clench the teeth and housing enter the length of roller seating space between gas mouth to be achieved again the longest, its are inspiratory the process is undertaking again. ?
Principle of work of engine of pneumatics of * screw type?
Machine of screw type pneumatics is by the rotor of yin and yang of a pair of mutual and parallel clench the teeth (or weigh screw) rotational inside air cylinder, make rotor alveolar the air between produces periodic cubage to change ceaselessly, air is carried by inspiratory side along rotor axes to output side, those who realize machine of screw type pneumatics is inspiratory, reduce the whole process with exhaust. The mouth taking energy of life of pneumatics machine and gas outlet are located in the two end of housing respectively, the tine of the chamfer of shade rotor and in relief rotor by advocate electric machinery drive and rotate. ?
Does mechanic of * piston pneumatics make a principle?
Piston pneumatics machine is drive leather belt annulus to pass shaft coupling by electromotor direct drive crankshaft, drive connecting rod and piston staff, make the piston makes reciprocate inside compressor air cylinder, finish inspiratory, compress, the process such as eduction, will not have press or low-pressure gas step up, output store pressure inside coal tub. Among them, piston component, piston and cylinder wall and cylinder lid make the working pitch with alterable cubage, drive in brace connecting rod, the reciprocate compression with the gas inside implementation cylinder is made inside cylinder
