官厅水电站每台机的自动化回路中用有五个电磁阀,电磁阀直流电磁铁为9M3-1型,电压220伏,吸力12公斤,行程30毫米。五个电磁阀中有两种型式:一种用在总水源管上的电磁液压阀,即电磁铁带动液压分配阀,经液压阀放大操作阀门,控制水源开放与关闭,运行情况良好;另一种为直接操作式的电磁阀,分别装在蝴蝶阀主油管、水轮机轴承润滑水管、调相给风管上,运行中经常发生动作不灵、跳跃、甚至造成开启线圈烧毁,故每次开停机均须手动操作。
Guanting Hydropower Station automation circuit for each machine with five solenoid valves, solenoid valve solenoid DC 9M3-1 type, voltage 220 volts, suction 12 kg, stroke 30 mm. There are two types of five solenoid valves: one is used in the total water pipe on the electromagnetic hydraulic valve, the solenoid that drives the hydraulic distribution valve, the hydraulic valve to enlarge the operation of the valve to control the water open and closed, running in good condition; the other Species for the direct operation of the solenoid valve, respectively, installed in the butterfly valve main oil pipe, turbine bearing lubrication pipe, phase to the wind pipe, often in operation is not working, jumping, or even open the coil burned, so every time the shutdown All must be operated manually.
