Pneumatics machine, compressor, pump is people 3 kinds of machines of very easy confuse sth with sth else, this article takes everybody to understand this 3 person different point and easy and promiscuous place

Pneumatics machine is air compressor. Advocate if be used,reduce airy machinery product, be in a lot of places to be able to be used. For instance a of pneumatics machine the most commonly used function is can have air compression using as thereby motivation, apply in power industry more extensive. Still can use refrigeration and detached gas besides, carry gas to wait action a moment. Very main effect is being produced in the life and job. And compressor is floorboard. And compressor has a lot of sort, enrage compressor and sky to enrage compressor to wait a moment like cold intermediary compressor, hydrogen. Air compressor is one of compressor only, its compression agency is air, and compressor can be used compress a lot of things, it is air not just. Accordingly, of pneumatics machine and compressor divisional, resembling is Chinese and mankind same. The Chinese is to include in the mankind in this category, air compressor is included to be in compressor in this total concept, it is one of compressor.
Average person can think pump is pneumatics machine. But pump is in very long before what what say is piston pneumatics machine, empty now press is phyletic ” link ” more, screw machine, without oily machine, machine of pneumatics of energy-saving frequency conversion is waited a moment. The principle of pump and empty press still is discriminating.
The working principle of 2. pneumatics machine
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. By electromotor direct drive dynamic pressure shrinks machine, make crankshaft produces whirligig, drive connecting rod to make the piston produces reciprocate, cause change of air cylinder cubage. By the change at force of air cylinder internal pressure, through entering gas a powerful person to make air passes air filter (muffler) enter air cylinder, in reducing the travel, by at air cylinder cubage contractible, compress air to pass the action of exhaust valve, classics vent-pipe, one-way a powerful person (check valve) enter gas tank, achieve rated pressure 0.7MPa when exhaust pressure when stop automatically by pressure switch control machine. Fall to join automatically to switch of the pressure when 0.5 – 0.6MPa when gas tank pressure start.
The working principle of 3. pump
The engine of pump passes crankshaft of pump of two V-belt drive, thereby drive piston undertakes encouraging, the gas that makes guides through cop receiver. On the other hand receiver enrages cop to guide the gas inside receiver through again fixed inside the pressure regulator valve on pump, control the atmospheric pressure inside receiver thereby. When the pressure that did not achieve setting of pressure regulator valve when the atmospheric pressure inside receiver, from the gas that pressure regulator valve enters inside receiver cannot when opening; of valve of pressure regulator valve to achieve the pressure of setting of pressure regulator valve when the atmospheric pressure inside receiver, from the gas that pressure regulator valve enters inside receiver the top opens valve of pressure regulator valve, enter the morale talk that is interlinked with pressure regulator valve inside pump, the opening taking energy of life that dominates pump through be being enraged often leaves, make pump no load thereby movement, achieve reduce dynamical loss, protect the purpose of pump. When the atmospheric pressure inside receiver when the because of loss pressure under setting of pressure regulator valve, the valve inside pressure regulator valve answers his by return spring, disconnect the control gas district of pump, pump begins to encourage afresh again.
