摘要
冷端密封间隙调整装置采用Z-80A单板机与其它功能板组成微机控制系统。由微机单元、执行机构、测量传感器、被控对象(密封间隙)等组成闭环控制,使密封间隙控制在0.5mm—9.9mm范围内,可将泄漏减至最低程度。
The cold end seal play control for the air heater is a computer-based control system composed of Z-80A single board computer and other function boards. Computer unit,actuators,sensors, controlled object(seal play ) form a closed control loop which keeps the seal play in the range of 0.5-9.9mm to minimize air hearter leakage.
