The blast-proof electromagnetic locks are applied primarily to the safety door locks of wellheads in the absence of gas from coal mines, and as the implementing agency for the locking device, the locking function is performed. It can also be used for the locking of the underground distribution room under the coal mine, which is not sprayed by gas, and the door of the well, which is transported by a cable motor vehicle, and the main electrical room along the tunnel. It can also be used separately。
Ds-30-i/ds-30-ii detonated electromagnetic lock-specific parameters:
Name: detonated electromagnetic lock
Model: ds-30i-1
Work voltage: 127v
Main lock current: 0. 85a
Locked current: 0. 48a
Name: detonated electromagnetic lock
Model: ds-30ii-2
Work voltage: 220v
Main lock current: 0. 8a
Lock currents: 0. 4a
Activation of blast-proof magnetic locks in mines:
When the ds-30 emp locks access the power source, unlock the power, lock it automatically after it has been cut, use a special structure, lock the sublocks into a circle group, generate a strong magnetic field that attracts the main lock when the main lock is signaled, locks it in a sublock, performs the unlock function, attracts the sublock core, automatically releases the main lock core and performs the locking function。
Use of attention:
1. When installed, the electromagnetic lock shall be vertically down。
2. The relative installation position of the electromagnetic lock and trough is appropriate to reach the 15-20mm depth of the lock, and the lock should be at the centre of the trough。
3. It is advisable to first use the four core cables of ø8-ø12 mm for the cable outlet that introduces the electromagnetic lock cavity。
4. This electromagnetic lock works intermittently and cannot be * driven to avoid burning。
5. When the electromagnetic locks are to be repaired, the electric cap shall be cut first。
