Universal coupling of wind turbine

Wind turbineUniversal couplingThe main fan unit is a three-unit coaxial unit. The flue gas turbine and the main fan are not connected by the current coupling, but by the 3S clutch produced in the UK. The advantage of the 3S clutch is that the flue gas turbine has Larger maneuvering flexibility, the flue gas turbine can be started and stopped at any time according to the production needs or the condition of the flue gas turbine equipment itself, without affecting the normal operation of the main fan. The 3S clutch can automatically realize the flue gas turbine shaft according to the speed of the flue gas turbine. It is separated and closed with the main fan shaft, but the 3S clutch also has the characteristics of sometimes large vibration.Due to various reasons such as the delivery period, the main fan was updated and transformed with a coupling instead of the original 3S clutch. The load of driving the flue gas turbine was considered when the main fan motor was selected, that is, the flue gas turbine was not put into use. Or the motor drives the flue gas turbine and the main fan to roll at the same time when the work is started, but when the flue gas turbine equipment itself fails, it is impossible to stop the flue gas turbine alone as with the 3S clutch, but the main fan unit can only be stopped and unlocked. The logical relationship between the flue gas turbine and the main fan.The original main fan instrument control system is the FC series instrument, the mechanical measurement instrument is the 7200 series instrument produced by American BENTLY Company, and the interlocking protection system is realized by the American M-84 programmable controller.
