摘要

离心式冷水机组喘振严重影响冷水机组的稳定性和使用寿命，当机组发生故障时应及时进行故障分析。故障分析可以采用运行数据对比的方法进行初步判定。在某医学实验中心空调系统离心式冷水机组喘振故障分析中，依据离心式冷水机组的结构、运行特点和喘振机制，通过现场勘查及运行数据对比，分析得出导致冷水机组喘振的原因为冷凝压力过高，并通过对外围设备运行状况检查和检修，解决冷凝压力过高的问题，最终缓解该机组的喘振现象，验证了数据分析的可行性，为技术人员在分析处理此类故障时提供参考。

Abstract

The surge of centrifugal chiller seriously affects the stability and service life of chiller. Fault analysis should be carried out in time when surge happen. The fault analysis can adopt the method of operation data comparison for preliminary judgment. In the surge fault analysis of centrifugal chiller in the air conditioning system of a medical experimental center

according to the structure

operation characteristics and surge mechanism of centrifugal chiller

through on-site investigation and operation data comparison

it is concluded that the cause of surge of chiller is too high condensation pressure

and the problem of too high condensation pressure is solved through the inspection and maintenance of peripheral equipment. Finally

the surge phenomenon of the unit is alleviated

and the feasibility of data analysis is verified

which provides a reference for technicians in analyzing and dealing with such faults.
