Mining explosion-proof starter
Main model:
B/B./B/B/B
This product is explosion-proof electrical equipment for mining, according to / " B(3.)/Mining flameproof starter" product standard production, as a starting device for explosion-proof diesel engines, it can be used in coal mines or other places with explosive mixtures such as methane and coal dust.
Main features: This starter is a four-pole DC series-excited explosion-proof motor. It adopts a roller-type one-way clutch to implement overspeed protection, and an electromagnetic switch controls the main contact circuit connection and gear meshing. This starter is a short-time working system, each working time is no more than seconds, and the interval is - seconds to prevent the starter from overheating and damage.
Working conditions:
.Ambient temperature -℃~℃
B

Notes:
The starter and explosion-proof power supply must be reliably connected with mining cables before use. Try to avoid long-distance connections.
Be careful to open the cover while the power is on and disconnect it from the external power supply before repairing
3. The one-way clutch and electromagnetic switch are non-detachable structures. If damaged, please replace the accessories before use.
Carry out regular maintenance, add grease and replace brushes from time to time according to the use environment.
If there is insufficient power, the starter will be difficult to start, especially in low temperature environments. Please pay attention during use.
Underground and non-professionals are not allowed to open the cover for maintenance
