The working time of underground coal bunker, water bunker, equipment chamber and other works in the coal mine is short. If the electric fan is used to connect the power and arrange the fan, it is very troublesome, time-consuming and labor-consuming. According to this situation, the company has developed FQ series mine pneumatic press in axial flow local fan, which is suitable for short-distance air supply during coal bunker, water bunker maintenance and roadway excavation.
Mining explosion-proof and intrinsically safe type multi-loop high-voltage vacuum electromagnetic starter is suitable for coal mine AC 3300V, frequency 50Hz, three-phase neutral point unearthed power supply system, local or remote control of three-phase asynchronous electric drive, to realize the centralized control of shearer, scraper conveyor, crusher, transfer machine, pumping station and other equipment in comprehensive mechanized coal mining face.
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.
The FJP series of mine spray dust suppression fans are used for dust removal in belt lanes, wind return lanes, and coal mining faces. The dust remover shall be placed on the top of the belt roadway, return air roadway, the rocker arm or body of the shearer or at the place designated by Party A. the underground high-pressure water pipe shall be inserted at the filter inlet, and the filter outlet shall be connected to the water inlet joint of the dust remover through the high-pressure rubber pipe, and the high-pressure water valve equipment shall be opened for operation.
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.
It is suitable for three-phase AC 50Hz, rated voltage 690V and below, rated current 4000A and below, in three-phase four wire system or three-phase five wire system and other power systems, used for power conversion, distribution and control.
It is suitable for the mine with explosive dangerous gas and coal dust. It can control and protect the start and stop of less than 4 three-phase squirrel cage asynchronous motors in the AC 50 Hz and rated voltage ac1140v (660V), and the phase sequence can be changed when stopping. It is especially suitable for the centralized monitoring of mining, transportation, coal mining and other dynamic loads.
Application: This product is applied to soft starting, soft stopping, operation process control and energy-saving application of motor in harsh environment such as coal mine, other mines, petroleum and chemical industry.
Application: this product is applied to soft starting, soft stopping, operation process control and energy-saving application of motor in harsh environment such as coal mine, other mines, petroleum and chemical industry.
The device is suitable for coal mine containing explosive gases like gas, coal dust, with AC 50HZ and voltage of 1140V or 660V. The ventilation of the driving surface and power supply are controlled by the device, with all control functions of dual power supply and fan.
It is suitable for communities, shopping malls, schools, supermarkets, substations, industrial enterprises and other power users, with Ac 50Hz, rated voltage 400V, 690V, rated current 1000 ~ 3150A power distribution system, used for power conversion, distribution and control device of the power, lighting and power distribution equipment.
It is a indoor high voltage switch equipment, applicable to 12 kv rated voltage, three-phase power system frequency 50 hz, used as protection and control electric equipment, as a result of the vacuum arc extinguishing performance is good, anti-fouling ability strong, almost maintenance-free special superiority, especially suitable for high current load frequent operation.
