Problems solved by technology

[0003] 1. The cooling pipeline system of the ship is complex, including water pumps, valves, mufflers and other equipment, pipeline components such as straight pipes, elbows, tees, and accessories such as pipeline supports and vibration isolators. The above equipment components can be The source of vibration and noise. After multiple equipment components form a system, the performance of equipment components will affect and limit each other, and the transmission of vibration and noise will also be coupled with each other.
It can be seen that the vibration and noise transmission of the cooling pipeline system is a complex process with multiple sources, multiple types, multiple paths, and multiple couplings, so it is difficult to evaluate the hydraulic and vibration and noise characteristics of the cooling pipeline system
[0004] 2. The low-noise operating conditions of each equipment component also have matching adaptability problems
There are many combinations and matching schemes of pump speed and valve opening to achieve the same cooling flow rate. In the scheme, the vibration and noise levels of the pumps and valves have opposite trends, and iterations must be repeated to obtain the best combination of pump speed and valve opening.
[0005] Therefore, the existing independent equipment vibration and noise characteristic test plus system vibration and noise transfer calculation method cannot comprehensively and accurately grasp the vibration and noise variation law of the entire cooling pipeline system, and realize low-noise operation under different working conditions

Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] This application discloses a low-noise operation control method for a ship cooling system based on real-time monitoring, please refer to figure 1 Shown in the flow chart, the method comprises the steps:

[0019] Step S1, determining the system operating characteristic map corresponding to the cooling system of the ship.

[0020] The system operation characteristic map stores sample operation data groups of the ship cooling system in different operation states, and the sample operation data groups corresponding to each operation state at least include the system flow rate, hydraulic balance matching scheme and vibration of the ship cooling system in the operation state. The noise data and the sample operation data group cover the entire range of the system flow of the ship cooling system, and the hydraulic balance matching scheme incl...

Abstract

The invention discloses a low-noise operation control method of a ship cooling system based on real-time monitoring, and relates to the technical field of ships. The method is based on the system flow, hydraulic balance matching scheme and vibration and noise data of the ship cooling system in different operating states to construct a system The operation characteristics map, according to the system operation plan given by the map that meets the system operation requirements, is used to control the system working conditions, and finally select the plan with the smallest vibration and noise data for execution. The formation process of the control plan is more scientific, the execution response speed is faster, and The mutual matching relationship between pipeline equipment can be considered, and the accuracy and engineering applicability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a low-noise operation control method of a ship cooling system based on real-time monitoring. Background technique [0002] To realize multi-working conditions and low-noise operation of the cooling pipeline system of a ship, two basic conditions must be met: 1. Fully grasp the change law of vibration and noise at the system level; Condition points match. However, it is difficult to achieve these two points at present, mainly because: [0003] 1. The cooling pipeline system of the ship is complex, including water pumps, valves, mufflers and other equipment, pipeline components such as straight pipes, elbows, tees, and accessories such as pipeline supports and vibration isolators. The above equipment components can be The source of vibration and noise. After multiple equipment components form a system, the performance of equipment components will affect and limit each other, and th...
