一九五四年八月,我们参观了东北区劳动保护展览会,对安全与生产统一的方针,有了较明确的认识。在先进经验的鼓舞与启发下,我们已集中力量改进与创造了几项较适用的安全措施,如马达起动安全装置,瓦斯警报器,缺油指示灯等,尚有几项因技术条件的限制,正在继续研究中。(1)马达起动安全装置:为了避免操作人员在起动马达时,因违反操作规程而造成重大事故起见,首先我们仿照了高压送电切断器的原理,在高压氨水泵上增添了安全设备(见图Ⅰ)。
In August 1954, we visited the Northeast Labor Protection Exhibition and had a clearer understanding of the policy of unifying security and production. Inspired and inspired by advanced experience, we have focused on improving and creating several more appropriate safety measures, such as motor starting safety devices, gas alarms, and lack of oil indicators. There are still several restrictions due to technical conditions. , is continuing to study. (1) Motor starting safety device: In order to avoid the operators causing serious accidents due to the violation of the operating procedures when starting the motor, we first modeled the principle of the high voltage power transmission disconnector and added safety equipment to the high-pressure ammonia pump (see Figure I).
