The role of fluid coupling

In liquid oil as the working medium of the liquid by the pump wheel into mechanical kinetic energy of the motor and the working machine can be connected to the power transmission implementation. Hydraulic pipe fittings It has a load to start the motor, a smooth CVT, etc., used to adjust the speed ofthe pump station to simplify the boiler feed water control system, reducing the number of high-pressure valves, due to the water by changing the speed and pressure to adapt to the unit from stop and load change, adjust characteristics, before and after the valve pressure drop, piping loss is small, difficult to damage, reduce the water supply system failure, occurs when the feed pump jam, killed, etc., are available from the pump and motor to the protective effect. Therefore, the modern power plant, boiler feed pump unit with hydraulic coupling generally adopted The governor will feed pump.
