浙江省电力安裝公司火电工程处,安装的一台1,500瓩鼓风机,在試轉中发生危急保安器轉速不对。按照从前的做法,是停机后将前面的盖拆开进行調整,調整好后,再将盖装上。这样一拆一装,不仅很費时間(一次約需要一个半小时),而且还不能保証一次調整成功。艮山門电厂新装的两台6,000瓩机,也曾因此而停机两次。为了消除这項缺陷,使設备早日投入生产,制成了調整危急保安器工具(見附图)。这个工具的特点是:制造簡单,使用方便。只要将工具插进彈簧外壳两条槽中,就可进行調整,每次只需15分
Zhejiang Electric Power Installation Company Thermal Power Engineering Department, the installation of a 1,500 瓩 blower, in the trial occurred in the critical safety gear speed is wrong. In accordance with the previous practice, after the shutdown will open the front cover to adjust, adjust, and then cover. Such a disassembly, not only time-consuming (one about an hour and a half), but can not guarantee a successful adjustment. Genshan door plant newly installed two 6,000 瓩 machine, has also been down twice. In order to eliminate this defect, the equipment was put into production as soon as possible, and a tool for adjusting the emergency security device was made (see attached figure). This tool is characterized by: easy to manufacture, easy to use. Just insert the tool into the two grooves of the spring case and adjust it, just 15 minutes at a time
