一、对蝴蝶阀工作油路的改进该发电机(单机容量1500千瓦)蝴蝶阀的操作配压阀电动机刹车有时失灵,不能正常工作,手动操作不便;特别是主配压阀的水活塞阀配合面易锈蚀,有时影响开机和停机,对安全生产十分不利。为了解决锈蚀问题,曾经多次检修,每检修一次只能工作不长时间,随后又发生新的锈蚀现象。为了彻底解决上述问题,技术人员根据蝴蝶阀油路工作情况,改进了油路管道,除去了操作配压阀和主配压阀,增装了四只电磁阀和四只闸阀(具体安装详见附图),分别为电动和手动操作。开机和停机的操作过程是:电动机开机操作1、2号电磁阀,停
First, the improvement of the butterfly valve work oil The butterfly valve operation of the generator (single capacity of 1500 kW) with the pressure valve motor brake sometimes fails, can not work properly, manual operation inconvenience; especially the main pressure valve with water piston valve with Surface easy to rust, and sometimes affect the boot and downtime, is very detrimental to the safety of production. In order to solve the problem of corrosion, it has been repeatedly overhauled, can not work for a long time after each inspection, and then new rust phenomenon occurs again. In order to completely solve the above problems, technical personnel based on butterfly valve oil road work, improved oil pipeline, eliminating the operating pressure distribution valve and the main pressure valve, an increase of four solenoid valves and four gate valve (see the specific installation Figure), respectively, electric and manual operation. Boot and shutdown of the operation process is: the first motor solenoid valve operation, stop
