YA-1型肺通气量仪在测定工人肺通气量方面,虽具有流量、计时、计算数字显示等多功能。但在高温环境中测试问题尚未解决。 去年,我厂开发劳动强度分级调查时,让被测者背着仪器接近作业现场工作3～5分钟,发现该仪器外壳发烫,而流量、计时、计算、显示数字均都消失。为了使仪器在高温环境下正常运转,经返复选材试验。选用一种比重小,热导小,柔软性好、耐高温、耐腐蚀的隔热材料上海碳素厂产的碳毡。
YA-1-type pulmonary ventilation meter in the determination of workers pulmonary ventilation, although with flow, timing, calculated figures show that multi-function. However, the test problem in high temperature environment has not been solved yet. Last year, when I conducted a grading survey on labor intensity, I was told to carry my instrument close to the job site for 3 to 5 minutes and found the instrument’s case was hot. The flow, timing, calculation and display figures disappeared. In order to make the instrument operate normally under high temperature, the material selection test will be repeated. Use a small proportion of small thermal conductivity of small, good flexibility, high temperature, corrosion-resistant insulation materials carbon plant in Shanghai carbon felt.
