ZL.72-DS-30 Explosion proof Electromagnetic Lock for Mining Safety Doors

I. OverviewExplosion proof electromagnetic locks are mainly suitable for the safety door locking device at the wellhead of coal mines without gas distribution. As the actuator of the locking device, they implement the function of locking the safety door.
It can also be used for the locking of underground distribution chambers without gas emissions in coal mines, as well as for the locking of shaft doors in tunnels transported by overhead electric locomotives and the main mechanical and electrical chambers along the tunnels.
It can also be used separately.
The explosion-proof electromagnetic lock is a general structure for mining, with a protection level of IP54. It has fast locking and unlocking action speed, large stroke, high reliability, stable performance, good anti smashing strength, wide working voltage range, and is an intermittent instantaneous worktable, which saves electrode consumption. At the same time, it does not need to change the original working mode of the mine when used, and can directly use the 127V and 220V AC voltage of the mine. Installation, use, and maintenance are also very convenient.
2、 Technical parameters of explosion-proof electromagnetic lock (1) Technical indicators a. Working voltage: 127V 220V AC b. Rated power: 50HZ c. Main lock working current: 0.5A Unlocking auxiliary lock working current: 0.35A Locking d. Rated stroke: 30mm e. Operation frequency: 500 times/hour f. Rated action time: 2 minutes (2) Environmental conditions for use a. Altitude not exceeding 2000m b. Working environment temperature -20 ° -40 ° C. When the ambient temperature is 25 ° C, the maximum relative humidity is 95% ± 3 d. In the absence of severe shaking and vibration and inclination from the vertical plane not exceeding 5 ° e. In the absence of methane and coal dust f. In the absence of dust, which is sufficient to corrode the metal box and damage the insulation. g. In the absence of direct water spraying
