Pneumatic butterfly valve daily maintenance cylinder debugging method and the matters needing attention

. Electromagnetic pneumatic valve and muffler check maintenance
every month for electromagnetic pneumatic valve for inspection and maintenance, check solenoid pneumatic valve mainly for dirt block, pneumatic valve core activities whether freely, muffler to have dirty plugged up, whether unobstructed. Air is clean water.
。 Cylinder inspection maintenance plan
usually do cylinder surface clean and axis of cylinder gas spring, open the cylinder end cover regularly every month check the presence of impurities and moisture in the air cylinder, and grease. Such as lack of grease or already dry solid, the cylinder must be open for full maintenance cleaning after add grease.
。 Pneumatic valve body check
check pneumatic valve body appearance is good, every month have installed flange without leakage, if it's convenient to check the pneumatic valve seal are in good condition, no wear and tear, and pneumatic valve plate operation is flexible, pneumatic valve presence of foreign bodies stuck.
。 Cylinder block disassembly and assembly method and the matters needing attention
the first will be detached from the pneumatic cylinder body, first unwrapped cylinder heads, piston down when must pay attention to the direction of the piston rack, and then use outside clockwise rotating cylinder axis piston run to the outside, then close the pneumatic valve hole ventilation gently with pneumatic piston top out slowly, slowly but this method must pay attention to ventilation, or piston will suddenly, a bit dangerous! Then put the cylinder shaft circlip tear down, cylinder shaft can take out from the other end. For each part to clean up, and then you can add grease, add grease parts as follows: the cylinder wall and piston seal, rack and the back ring, and the gear axis and seal ring. After add good grease will be installed in the disassembly sequence and place an order, it is important to note that the position of the gear and rack, make sure the pneumatic valve in open position is the position of the piston shrink into the gear shaft when the upper groove parallel to the cylinder block, pneumatic valve position when the piston to the outside to the position of the gear shaft upper trough and vertical cylinder block.
。 Cylinder and pneumatic valve installation and debugging method and the matters needing attention
will first pneumatic valve with external forces in the closed position, namely the pneumatic valve shaft clockwise until the pneumatic valve plate and seat sealing contact, at the same time, the cylinder is placed in the closed state of pneumatic valve ( The cylinder shaft above the small groove and the cylinder body into a state of vertical, for clockwise rotation to close the pneumatic valve pneumatic valves) And then to a pneumatic cylinder valve ( The installation direction and pneumatic valve parallel or vertical) , see if the screw hole for again, won't have too big deviation, if you have a little deviation, cylinder block turning point, then tighten the screw. Debugging pneumatic butterfly valve, pneumatic valves to check parts whether the installation is complete, the electromagnetic pneumatic valve and muffler, etc. , if there is not complete, not debugging, for a gas pressure is normal. MPA±. MPA, run to ensure that the pneumatic valve body without sundry card before pneumatic valve plate in place, for the first time debugging runtime with manual operating electromagnetic pneumatic valve manual button ( Manual operation when electromagnetic solenoid coil electric, manual operation is valid; Electric control operation puts manual twist, electric operation is valid, to close the pneumatic valve, pneumatic valve to open, quick open the pneumatic valve, close the pneumatic valve losing electricity if you need to close the pneumatic valve, pneumatic valve will open, install the electromagnetic coil rotation of the pneumatic valve) Pneumatic valve operation and observation. If found in the process of debugging run pneumatic valve pneumatic valve is in the starting position is slow, but as long as the action soon after, this kind of circumstance is pneumatic valves are closed tight, just put the cylinder stroke (a little On both ends of the cylinder stroke adjusting screw to adjust a bit at the same time, the adjustment when the pneumatic valve must be running to the open position, and then dispatch air off again) Easily transferred to the pneumatic valve is opened and closed in place does not leak. If the silencer for adjustable muffler can adjust the switching speed of pneumatic valves, muffler must be adjust to pneumatic valve switch speed is suitable for the opening. If a tuning is too small, may not be able to make the pneumatic valve action.
