[0004] In order to improve the reliability of water pumps and pumping stations, the current technical route is mainly combined with the pumping station process to carry out corresponding redundant configuration and protection, such as adding redundant pumps, redundant power supply, overload and overcurrent phase loss protection, flow pressure temperature protection, etc. , switch or alarm in time according to the operation situation, repair and replace the equipment after the failure, but it is difficult to analyze the cause of the potential failure, and the relevant information cannot be obtained in advance before the failure, and the problem cannot be completely solved. It is necessary to establish a complete set of water pump health monitoring With the diagnosis and analysis method, the potential hidden dangers of the water pump can be monitored, and the precise location of the fault and the severity of the fault can be obtained according to the diagnostic information

Embodiment 1
[0076] Such as figure 1 As shown, the present invention is a water pump health monitoring and diagnosis method for a circulating water cooling system, and the method is specifically:
[0077] S1. Pre-store the data information of the pump in normal operation state;
[0078] S2. Obtain five types of data information on the real-time operation of the water pump;
[0079] S3. Analyze the five types of data information respectively and compare them with the data information in the normal operation state to generate a comparison result;
[0080] S4. Analyze the health indicators of the five types of data through different weights, and generate health indicator analysis results;
[0081] S5. Monitoring and diagnosing the failure of the water pump by comparing the results with the analysis results of the health indicators.
[0082] The five types of data are: one type of electric energy and hydraulic data, two types of vibration data, three types of leakage data, four types of noi...
Embodiment 2
[0128] This embodiment includes all the technical features in Embodiment 1, and at the same time, provides detailed judgment methods about health indicators:
[0129] The described pump health index is H(i):
[0130] H(i)= ×EQH+ ×VH+ ×NH+ ×WH+ ×TH+ ×CLH;
[0131] Among them, EQH is the electric energy and hydraulic index, VH is the vibration data index, NH is the noise data index, WH is the leakage data index, TH is the temperature data index, CLH is the key component life index, is the weight.
[0132] In specific implementation, the weight can be set as follows: Weight 15%, Weight 25%, Weight 10%, Weight 25%, Weight 15%, Weight 10%.
[0133] When Hi≥90; running in good condition;
[0134] 90
[0135] 75
[0136] Hi<60; the equipment is abnormal, which will lead to equipment damage. Through continuous monitoring, establish a...

Abstract
The invention relates to the technical field of water pump health diagnosis, in particular to a water pump health monitoring and diagnosing method for a circulating water cooling system. The water pump health monitoring and diagnosing method for the circulating water cooling system comprises the following steps that data information of a water pump in a normal running state is stored in advance; five types of data information of real-time operation of the water pump is obtained; the five types of data information is analyzed, and the five types of data information is compared with data information in the normal operation state to generate a comparison result; health index analysis is conducted on the five types of data through different weights to generate a health index analysis result; and monitoring and diagnosing are conducted on the fault of the water pump according to the comparison result and the health index analysis result. According to the water pump health monitoring and diagnosing method for the circulating water cooling system, through comprehensive judgment and analysis of multiple monitoring methods, potential faults of the water pump are found in advance, the severity degree and the position of the faults can be accurately analyzed, and maintenance opinions are given.
Description
technical field [0001] The invention relates to the technical field of water pump health diagnosis, in particular to a water pump health monitoring and diagnosis method for a circulating water cooling system. Background technique [0002] The pumping station composed of water pumps and water pumps is a mechanical device that transports liquids or pressurizes liquids. It transmits the mechanical energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspended emulsion, etc., and is widely used in urban water supply, HVAC, air conditioning and refrigeration, sewage , construction, power station, petrochemical industry, metallurgy, light industry, direct current transmission cooling, electronics, medical treatment, data center and many other fields. [0003] Water pumps and pump stations play an important role in the national economy and production. In some key areas,...
