Bus wing outside door open mechanism
Main techanical parameter:
1. Operating pressure: 0.5~0.8Mpa
2. Lift force: >1000N
3. Direction of rotation: Left(right)
4. Angle of rotation: 135 max
5. Height of lift: 20mm max
6. Voltage: DC24 (please indicate 12V if need when place an order)
Principle and Characteristic
This door pump is to compress air as the power of the door cylinder, electromagnetic valve change the direction, supply air to the upper and lower air chamber of cylinder respectivly, make pistons to move up and down, to make the spiral sets rotation by spiral device, then drive doors rotation, and control the open or close of door. When electromagnetic supply air to upper chamber of cylinder, pistons move down, spiral device make a clockwise rotation, then door open, otherwise, door closed. Adjust non-return throttle valve, can adjust the speed of open or close doors.
Self-locking function: When closing door, door close to door frame, so door can't rotate any more, but piston still do movement, then spiral device make door lift, and blocks in door and door frame locked; When opening door, piston will do reverse movement, drive door move down firstly, relieve self-locking, then open door by reverse rotation. |
