Voith manufactures 1000th TPKL fluid coupling

Voith recently manufactured its 1,000th TPKL fluid coupling. This coupling will go to the DaTong Coal Mining Group in China.

A new coal mine owned by the group will receive four TPKL fluid couplings. The fill-controlled couplings will be used in a 6.4 MW belt conveyor drive with demanding requirements. The 3.16m-long underground belt conveyor is driven by four 1.6 kW motors, with a planned capacity of 4.000 tonnes per hour.

Voith started the production of the TPKL coupling series in 1997. This fluid coupling type was especially developed for demanding belt conveyor applications in mining. The coupling type provides torque limitation for a smooth start-up of the belt conveyor and allows active load sharing with multi-motor drives. Thanks to its standstill cooling function it can handle the most difficult start-ups multiple times in succession.

DaTong Coal Mining Group is located in DaTong City, Shanxi province, China. It is one of the top three coal groups in China, with a coal production capacity of 152 million tons per year. The coal group operates a large number of coal mines across the country. Many of them use Voith fluid couplings in underground applications like AFCs, belt conveyors, stage loaders and crushers.
