MEASURING SYSTEM WATER LEVEL IN THE DRUM power boiler hydrostatic method

摘要

The solution relates to measuring equipment for remote measurement of feedwater level in the steam drum of power boilers. Proposed system for measuring water level in the drum of a power boiler, consisting of an equalizing vessel constant level, impulsive pipes connected to the water and steam space of the boiler, pressure switch having a plus and minus chambers separated by a membrane which is connected via rods with tenzopreobrazovatel, whose output is connected to the input of the electronic converter, a minus differential pressure chamber to introduce an additional contour gauge pressure, the same consists of a membrane connected via a second thrust tenzopreobrazovatel, whose output is connected to a second input of the electronic converter. It provides continuous monitoring and automatic control of permanent protection boiler at different modes of operation. 1 SP f-ly 1 Fig.
