Hammer Rock Mining Drill Machine

This product is mainly used underground in coal mines and has multiple protection functions. The human-machine dialogue of the product is easy to operate, with high measurement accuracy and stable and reliable protection functions. The product has convenient communication networking and is an ideal replacement product for building digital mines.

Application: Used in coal mines, in AC 50Hz, rated voltage of 660V or 1140V, rated current to800, 1000A three-phase neutral point undergrounded power supply system, as a main switch or branch switch, but also as a large-capacity motor infrequently for starting control.

It is used in coalminesin three-phase neutral ungrounded transmission lines with voltage AC 3300V,50Hz. It canmake local and remote control of three-phase asynchronous motor and concentrated control of coal cutter,scraper conveyor, crusher,reversed loader, pump station and other equipments of comprehensive mechanized coalfaces.

PLC (programmable logic. controller) programmable control cabinet is an electrical cabinet that can be programmed according to the needs of operating conditions, and can realize the automatic control of motors, switches and other equipment

KJS series mine pneumatic wet dust precipitator is designed to be suitable for dust removal in gas discharge drilling holes, Tunnel Shotcreting, tunnel driving, etc. the dust precipitator is placed next to the drilling machine and shotcreting mixer, the roadheader body, the second transport belt, or the place designated by Party A, and the underground high-pressure water pipe is connected to the filter inlet. The filter outlet is connected to the inlet joint of the dust precipitator through the high-pressure rubber pipe, and the compressed air is connected to the air inlet. Open the high-pressure water valve and air pressure valve for operation.

QJZ3-2400/1140(660)-8ML  mine explosion-proof and intrinsically safe type multi-loop  vacuum electromagnetic starter , it is applicable to the mine with explosive gas and coal dust. In the circuit with AC 50Hz and rated voltage of AC 1140 (660) V, it can control and protect the starting and stopping of 8  or less three-phase squirrel cage asynchronous motors at the same time, and can change the phase sequence when stopping. It is especially suitable for centralized monitoring of mining, transportation, mining and other working faces with concentrated power load.

Application:It is suitable for the dangerous environment of gas and coal dust explosion. Used for electrical control, monitoring and comprehensive protection of belt conveyor and other equipments in coal mine.

It is suitable for variable frequency asynchronous motor or ordinary asynchronous motor of AC 50Hz, motor power 11KW~1120KW, rated voltage 660V or 1140V to soft start, soft stop and operation process control under heavy load, its start, stop, process control curve can be set to “S” type curve, linear curve, function curve and other forms of curve.
