Hammer Rock Mining Drill Machine

The soft starter is suitable for coal mines containing explosive gas (methane) and coal dust.In an AC 50Hz, voltage 1140V or 660V, neutral ungrounded power supply system, various forms of soft start (such as current clipping, voltage ramp and power torque ramp) are performed on three-phase squirrel-cage motors with currents up to 200A and 400A.The controller also has the perfect protection function and the fault display function, greatly reduces the time of troubleshooting.

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

Taking advantage of the low-speed and high torque of permanent magnet motor, combined with the torque amplification function of planetary reducer and the control of frequency converter, the low-speed drive all-in-one machine has the smallest volume and the best performance. It is suitable for installation space limited and movable equipment.

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.

Mining explosion-proof and intrinsically safe low voltage AC soft starter (hereinafter referred to as starter) is suitable for mine containing explosive dangerous gas and coal dust. in AC 50Hz, rated voltage AC1140V (660V) power supply system, four three-phase squirrel cage motors with current below 400A can be started in many forms (such as current limiting, voltage slope and power torque slope).

It is also known as high voltage dynamic reactive power compensation generating device or static synchronous compensator, which is an equipment providing dynamic reactive power compensation through the self commutation of the power semiconductor bridge converter.

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.

Mining flameproof three-phase permanent magnet synchronous electric drum is a new low-speed and high torque external rotor permanent magnet motor independently developed by Wantai, commonly known as permanent magnet electric drum.
