Product details
The charge pump is an important component of the chemical and volume control system of nuclear power plant. It provides volume control, chemical control, sealing water injection and other functions for the reactor coolant system. Its safe and stable operation has a crucial impact on the safety and economy of the power plant. The pump is driven by the motor and the growth box, the growth rate is 1:3, the motor drives the drive shaft of the growth gear box, which is driven by the gear to the driven shaft, and the driven shaft drives the charging pump and increases the speed. The speed box is lubricated by oil, and is equipped with an air oil cooler, which is driven by an oil motor. The oil motor consists of two shafts connected by an intermediate involute spline. With the increase of running time, the spline will wear, and when the wear appears to a certain extent, the spline will lose the transmission function. This paper mainly combined with the experience feedback of spline wear treatment, the oil motor structure design and spline wear treatment are comprehensively studied and discussed, to provide technical support for the future operation and maintenance of the gear box.
