Application of hydraulic coupling in boiler

Nowadays, in most thermal power plants, the pressure of boilers is higher and higher, and the pressure to pump is higher and higher.

The drive speed of the hydraulic coupling is very important to the pump.

For the economical operation of the boiler, the best solution is to adjust the speed adjustment to the change of working conditions.

During which a solution is to choose direct transmission of small steam turbine to drive the feed water pump, but it must have a backup in the unit startup steam source to adapt to the needs, organization set up complex.

Another option is to use the hydraulic coupling to change the pump speed to get used to the starting condition of the unit.

So on the one hand can be dramatically reduced electric equipment allowance of feed water pump motor, make the speed of the feed water pump can be smaller than the start, on the other hand will not render constant speed motor pump when the unit starting to save a buck for the working condition of habits, improve the economic benefit of the unit, and to avoid the high pressure valve due to save in a short period of time is invalid due to erosion, wear phenomenon
