Explosion -proof electrical equipment is an electrical equipment designed and manufactured according to national standards that will not cause the explosion of surrounding explosive mixtures. In coal, petroleum, chemical industry and other industries, the production environment and explosive substances are different, and explosion -proof measures are also different. The safety operation of explosion -proof electric gourds is as follows:
1. It is strictly forbidden to use it in an unwanted environment and exceeding the rated load.2. It is forbidden to operate personally without training or obtained special equipment operation qualifications.
3. When operating, the machine is not allowed to be lifted and the horizontal drag tool is used.
4. Limiters prevent the safety device that causes the accident setting when the hook is rising and decreased by the limit position, so the limiter cannot be used as a switch.
5. After the work is completed, the total switch of the power supply must be opened to cut off the main power supply.
6. Normally use steel wire ropes lubricated at least once a month. When the temperature is low in winter, it must be coated with lubricating oil. Lubricating oil should be cleaned and should not contain impurities and dirt.
7. Before each use, check whether the steel wire rope is bent, knotted, whether the rope stocks are prominent or too reversed, the surface has a sign of twisting, whether the rope stock and individual steel wire are broken, the end of the rope is firm, whether the steel wire rope is clean, whether the wire rope is clean, whether Is lubricating oil sufficient?
8. During use, if a bad failure is found, the main power should be cut off immediately.
9. After the explosion -proof electric gourd is used, it should be stopped at the designated place, and the hook rises to a position of more than 2 meters from the ground.
10. When running, prevent and avoid hazardous sparks that can ignite the dangerous mixture of explosion.
