Title: Water-level control method of deaerator
Inventor: AKASHI TEIICHIROU
IPC: G05D9/00
Filed: 1980-12-16
Abstract: PURPOSE:To efficiently control a water-level of a deaerator of a heat power plant, by controlling the rotational frequency of a condensing and boosting pump under the control of a fluid joint, and controlling a flow rate of condensation to a deaerator from a condenser. CONSTITUTION:A fluid joint 20 is placed between each condensing and boosting pump 5, and each driving motor 4, and a rotational frequency control device 21 is attached to the joint 20, respectively. For instance, when a water-level detector 13 of a deaerator 1 detects a drop of a water-level, the detector 13 sends a signal to a deaerator water-level control device 15, the signal controlled and operated by the device 15 is sent to the device 21, and rotational frequency of the joint 20 is increased by a rotational frequency increasing command. As a result, the rotational frequency of the pump 5 is increased, a flow rate of condensation sent to the deaerator 1 from a condenser 2 is increased, and a water-level of the deaerator 1 rises up to a prescirbed water-level. Also, in case when the water- level rises, the water-level of the deaerator is adjusted by decreasing the rotational frequency of the pump on the contrary, and decreasing the flow rate of condensation.

IPC: G01F23/66
Filed: 1989-07-11
Abstract: PURPOSE:To measure a level in a connection position by providing a main pipe with a joint part in a prescribed measuring position and connecting a measuring pipe, as necessary. CONSTITUTION:When a joint part 11 of a measuring pipe 1 is connected to a joint part 10 placed in a prescribed measuring position of a main pipe 2, the measuring pipe 1 and the main pipe are connected and the liquid level rises. The liquid level is measured based on the output of a detector 15 after settling of the liquid level to clarify the level in the position where the measuring pipe 1 is connected. After measurement in this position, the measuring pipe 1 is detached from the joint part 10 and is moved to the next measuring position. Liquid is not leaked from the position from which the measuring pipe 1 is detached because a check valve 12 of the joint part 10 is closed at this time, and liquid in the measuring pipe 1 itself does not flow out in the same manner. The measuring pipe 1 is connected to the joint part 10 in the next measuring position to measure the level in this position.
