DN(50~300)mm大口径热量表检测装置较为复杂,且造价昂贵,对安全性要求较高。本文逐一分析了大口径热量表检测装置的加热系统、稳压系统、夹表系统、回水系统、气路系统、流量控制系统、恒温水槽以及标准铂电阻温度计方面的安全因素,其中加热系统的安全性尤其需要重视。通过认识这些安全因素,指导检定人员正确操作,保证大口径热量表检测装置的安全使用,降低装置的维护成本,提高整个装置的使用寿命。本文的研究内容对类似装置的安全维护有一定借鉴意义。
DN (50 ~ 300) mm large calorimeter detection device is more complex, and expensive, high security requirements. This article analyzes one by one the heating system, the regulator system, the clamp system, the backwater system, the gas system, the flow control system, the constant temperature water tank and the standard platinum resistance thermometer safety factor of the large calorimeter detection device, in which the heating system In particular, safety needs attention. By recognizing these safety factors, we can instruct the verifiers to operate correctly, ensure the safe use of the large-calorimeter detector, reduce the maintenance cost and improve the service life of the whole device. The research contents of this paper can provide reference for the safety maintenance of similar devices.
