Three, pneumatic driving device structure characteristic and main component and part

1, axle bearing [metal lining PTEE] friction coefficients small , lubricate to seal off effect well. 2, baffle plate [HT200 (FC200)] makes an air chamber isolate from the organization turning round , cuts down air consumption , prevents dead person from carrying out an air cylinder , at the same time, is piston guiding , ensures that action is stable. 3, enters gas mouth [RC1/4, 3/8 , 1/2]. 4, the piston [HT200 (FC200)] is deft be able to bear pressure , the propulsive force losing the sex minor , sealing up completely well. 5, the piston rod [45 (S45C + HCr)] intensity is high , the surface plates with the hard chromium , able to endure mean. 6, plates with the hard chromium axis pin [45 (S45C + HCr)] outside , balances piston rod output power supplying with a shift fork. 7, hand movement worm gear operation implement assembles platform 8, scrolls [45 (S45C + HCr)] are able to endure mean. 9, air cylinder [QT450-10 (FCD450)]. 10, 5 degree of position-limit double-screw bolt adjustment switch angle , respectively adjustable positiveness and negativeness of switch. The O type circle [NBR] is water-proof 11. 12, shift forks, [QT450-10 (FCD450)] changes linear motion into the motion turning round , the valve exporting force moment characteristic property adapting to the middle heavy calibre twists from characteristic property. 13, the box experiences and observes [HT200 (FC200)].

Double movement type characteristic: 1st, dials the fork transmission system, its output pitch of strand characteristic suits in the heavy-caliber valve actuates the pitch of strand characteristic. 2nd, the air chamber and the swiveling mechanism isolate, the air consumption are few. 3rd, the two-cylinder double-piston, the output strength is big. 4th, the volume is small, the weight is light, perform reliably. 5th, works P:0.3-0.7MPA ambient temperature T:-20-+80

And dyadic Shan action spring replacement Shan action spring place style pretends to have the spring jar in AW type one side side of pair of air cylinders, pressure adapting to two kinds operation, the athlete selected for a sports meet moves device (HW , the side hand wheel). AW-S: Standard form P: 0.4-0.7MPA AW-L: Low pressure type P: AW13L; 0.25-0.40MPA AW17L:0.23-0.36MPA AW20L:0.28-0.46MPA AW28L:0.24-0.39MPA AW35L: AW40L:

Four, pneumatic driving device pair of action style and Shan action style exterior dimension picture

Six, AW type pair of action style exports the moment of torsion form

Seven, AW-S type Shan action style exports the moment of torsion form

Eight, pneumatic driving device air wastages secretly scheme against

Nine . The air-operated drive equipment selects with the installation and trial run and the maintenance. 1. before selecting the pneumatics considered first valve’s pressure, the temperature, the medium, then determines valve’s torque strength: The lubricating fluid increases 20% to take the safety coefficient; The pellet powder lot medium increases 65% to take the safety coefficient, acts according to again was mad that the hydraulic pressure selects the double movement type or the single movement-like torque, the determination air-operated drive equipment model. 2. Before the pneumatics and the valve install, must achieve: 1. valve lever and pneumatics main axle on identical spool thread;
2. The connector and the chassis go through accurate machine work; 3. Ascertain valve operation way (Chang come untied or normal close) , the chassis linking up is assembled on the valve; 4. Ascertain a chassis linking and assembling what be needed direction (straight line or cross spider) a angle , revolution valve stem to get to necessaries handle necessary location; 5. Forbid dismantling the valve being pressed on , use appropriate safety procedure to be a pneumatic device, the installation linking a chassis’s is equipment; 6. And then dimension examining that the transmission shaft is suitable including the axis implement and the pneumatic device, the connector uses bolt and valve holder to firm , be OK to pay attention to a valve stem with pneumatic device transmission shaft alignment and implement joint is appropriate including the axis.
3. The pneumatic device is scene appearance , should carry out an upkeep at the regular intervals and takes good care of. Carry out the implement gas source responding to keep clean , clean; The air-filter go along that corresponding to pneumatic device composition uses turns on the water , blows off at the regular intervals, affect the regular job to avoid entering electromagnetic valve and carrying out an implement. Under regular usage situation, respond to every six months check an once , examine and repair an once every year. Ten. Pneumatic driving device accessories function and use. Pair of pneumatic effect driving devices: Control a valve opening an account and being closed down;
Pneumatic driving device of Shan effect: Circuit , the gas road are broken up or are close a valve voluntarily when faulty,; The Shan electricity charges electromagnetic valve: The valve opens (be closed down) current supply now and then , the valve closes (open) when blackout;
Pair of electricities charge electromagnetic valve: The valve opens a coil when electrify , the valve closes when another coil electrifies. Have the memory function; Answer the message implement: Distant distance delivers valve switch location signal; Electrical equipment locator: The aperture to the valve (is medium according to the size of electric current signals (4 ~ 20 mA) rate of flow) carries out adjustment under the control of; May provide the pneumatic type’ locator preventing explosion equally: According to the size of pressure signal (0.02 ~ 0.1 Mpa), control the valve aperture , carry out adjustment under the control of; Pneumatic trigeminy document: Pressure reducing , filter , oil fog implement. To gas source stabilivolt,clean and move component lubrication action; Hand takes up organization: Pawn circuit , the gas road when breaking a malfunction up or having , be used to handle the valve starting and stopping.十一. The points for attention driving device ordering goods is a complicated automation check meter , the consumer control need in the light of , choose following accessories detailedly, and give clear indication of on technology contract to be made up of pneumatic various component. 1, pneumatic driving device: A moves an effect pair , b moves the effect c type only 2, electromagnetic valve: A charges electromagnetic valve b for charging electromagnetic valve c for using the average type of voltage d explosion protection type e pair only 3, the signal couples back: Dyadic a machinery switch b induced average type of dyadic switch d explosion protection type e

4, locator: 5, makes the average type of pneumatic valve of a electricity valve locator b locator c electricity converter d explosion protection type e angry the source sells the trigeminy document at reduced prices: 6, moves a fliteration pressure reducing b oil fog implement personally handling organization 7, peculiar interface dimension 8.
