Variable-working-condition low-noise regulating and controlling device for ship cooling system and regulating and controlling method thereof

Abstract

The invention relates to a variable-working-condition low-noise regulating and controlling device for a ship cooling system and a regulating and controlling method thereof. The variable-working-condition low-noise regulating and controlling device for the ship cooling system comprises a control host composed of a processing module, a communication module and a man-machine interaction module; the input end of the processing module is connected with state monitoring devices, and the output end of the processing module is connected with regulating and controlling devices; the state monitoring devices are components which are arranged in cooling system pipelines and used for monitoring the temperature, the flow, the pressure and the noise of the cooling system pipelines in real time; the regulating and controlling devices comprise a frequency converter and an electric regulating valve; and the processing module is used for acquiring real-time data of the state monitoring devices through data acquisition cards, conducting comparison and analysis, conducting running configuration on a low-noise interval according to hydroacoustic characteristic curves of the regulating and controlling devices when the working condition changes and sending current signals to the regulating and controlling devices for execution after personnel determine the scheme, therefore, system main equipment runsin the low-noise interval, and the system running noise level is reduced. According to the variable-working-condition low-noise regulating and controlling device for the ship cooling system and the regulating and controlling method thereof, remote control over low-noise regulating and controlling is achieved, operation is easy and convenient, the adjusting precision is high, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of regulating and controlling the cooling system of a ship, in particular to a low-noise regulating device and a regulating method thereof under variable working conditions for the cooling system of a ship. Background technique [0002] The ship cooling system includes main equipment components such as heat exchangers, cooling water pumps, and regulating valves. The cooling water medium is driven by the water pump to run in the system pipeline, and the heat flow is exchanged with the high-temperature fluid medium flowing through the heating equipment in the heat exchanger. In this way, the heat is taken away, and the cooling function of the ship equipment is realized. [0003] Considering the functional safety in the design of the ship cooling system, the equipment is generally selected according to the maximum working condition, which not only results in high power redundancy, but also makes the operating c...

Problems solved by technology

[0004] In the prior art, most of the variable working condition control for the pipeline system is aimed at reducing the energy consumption of the system, and the operating power of the equipment is used as the control target parameter. There is no control system that takes the acoustic characteristics as the control target parameter, and the used The degree of automation of the adjustment means is low, and the system adjustment task cannot be effectively completed when the operating conditions change greatly
