Cylinder use of the note;
1. The air quality standards
To use clean and dry compressed air. The air may not contain organic solvent synthetic oil, salt, corrosive gas, etc., in case of cylinder, valve action bad. Before installation, connection with tube should fully blow off, don't put dust, cutting end, sealing tape debris and other impurities into cylinder, valve inside.
2. To use environmental requirements
In the dust, the place of water, bar side should take expansion protective sleeve, installation, don't appear twist twist state. Can't use telescopic protective sleeve place, should be chosen with powerful shield of the cylinder or waterproof cylinder.
3. About cylinder lubrication
Give oil lubrication cylinder, should configure flow suitable oil mist device.
4. About cylinder load
Piston rod are usually can only carry axial load. To avoid in the piston rod applied lateral load and eccentric load. A transverse load, the piston rod should add guiding device, or choose to guide cylinder
5. About cylinder installation
Install stationary cylinder, load and the axis of the piston rod should agree. Installation earrings type and trunnion type cylinder, shall ensure that cylinder swinging with the load swing in a plane within. Otherwise, the light is seal eccentric wear, cause gas leakage, make the cylinder loss of life, Heavy then cylinder not action. Sometimes, cylinder also can appear impact action, may cause damage to the human body and device.
Cylinder field installation, want to prevent drilling chip from cylinder at the end of the inlet air in cylinder mixed.
Feet seat type cylinder if at the feet seat have positioning hole, can be used for positioning
Trunnion bearing support mounting surface from bearing distance is very large, attention should be paid to install the mounting screw shall not force is too big and damage.
With fixed cylinder make connection arm for circular motion, the arm long open hole shape, open long shaped hole should be considered in the guide sleeve on the lateral load by do not exceed the specified value.
Pin shaft and so on rotary should be coated with grease, in order to prevent the sintering.
Trunnion type cylinder don't decomposition, for ear shaft axis and cylinder axis after decomposition in assembly is difficult to ensure that fit well, can lead to bad of a cylinder.
In the piston rod end screwing in nut or installation accessories, piston rod must all to retract. To stem don't rotary type cylinder, piston rod on installation accessories, should be avoided in the piston rod under rotation moment. Tighten the piping thread, the strength should be appropriate, lest damage interface thread or leak.
6. Cylinder speed adjustment
Use speed control valve for cylinder speed adjustment, the throttle valve should be full close gradually is big, transferred to the speed of hope. Adjusting ring number no more than the most giant slalom turns. After the adjustment, will lock mother fastening.
7. Cylinder buffer
Cylinder energy of movement can't rely on cylinder completely absorbed, should be in external additional buffer organization or design buffer circuit.
8. Cylinder maintenance
Cylinder and piston rod of sliding parts shall not be damaged, in case of a cylinder bad, damage piston rod seal rings etc caused by gas leakage.
Buffer valve place should be set aside appropriate maintenance adjustments space, magnetic switch should be set aside appropriate installation adjustment space.
If a cylinder in a long need not, should be a month action once, and oil protection to rust.
9. About safety countermeasures
Cylinder for impact action, in drive a and fixed between parts, must design the brothers will not be clamping position.
Drive objects should add protective cover, cannot direct contact with the human body.
Midway stop cylinder, must pay attention because of air leakage occurred mobile cause accidents may.
High frequency action cylinder, cylinder to the high temperature, don't touch.
Due to the pressure drop, cylinder clamp not object, the lifting device's weight may fall, want to have prevent heavy fall, pressure drop security measures. Such as design a certain capacity of the tank in order to maintain gas pressure in a certain value above.
Cylinder in the specified position does not stop, endanger personal and device safety place, can install two layer limit switch, all kinds of sensor etc.
Power and emergency stop, to prevent the cylinder action cause personal injury and device, can let the pressure inside the cylinder remain unchanged or all emptying way.
Power and emergency stop after the reset, loop should be designed with manual let cylinder returns to the provisions of the respective position, and then carry on automatic operation. Let the cylinder return to a certain position, with the pressure reducing valve will pressure lower operation as well. Long time stop gas supply, not running mechanical to reset, also will be the same consideration.
10. Electromagnetic valve installation used, should pay attention to electric head control voltage, electromagnetic valve use manual knob operation must ensure that the state of power supply.
