Explosion -proof electric gourds have explosion -proof steel wire rope electric gourd and explosion -proof ring chain electric gourd, each with different applications. Electricity -proof ring chain of ore needs to meet the corresponding standards in order to use it in the mine plant. The specifics are as follows:

1. Mine-out explosion-proof ring chain gourd conforms to GB3836.1-2010 "Explosive gas environment for explosion-proof electrical equipment part 1: General Requirements" and GB3836.2-2010 "Explosive Gased Gas Environment Part 2 "D" ", 12476.1-2000" The 1st part of the electrical equipment for flammable dust environment: Electrical Equipment 1 with shells and limited surface temperature Section 1: Technical Requirements for Electric Equipment ".

2. Divided into factory explosion -proof DII and DI divided into factory.

3. Mine explosion -proof ring chain gourds can be used with fixed suspension tracks under the mine.

4. The weighing weight of the explosion-proof ring chain of the mine is 1T-10T, and the working environment temperature is -20 ° C -40 ° C.

5. The BHH series of explosion -proof ring chain electric gourds are mainly used for 660V power under the coal mines, consisting of three parts: motor, deceleration port, and hanging mechanism. The motor uses the YBez -type ore explosion -type tapered electrical motor. It has the characteristics of large power -making torque and instantaneous braking. After the motor is decelerated by a three -stage gear, the hook and the chain of the hook are driven to raise the hook.
