我厂SZL型双纵汽包链条锅炉,因油泵电动机经常换向,振动剧烈,齿轮泵反向,困油造成弹性联轴节损坏,油泵电动机轴也易断裂。为解决这个问题,我们对锅炉液压电气部分进行了改革,即在液压系统回路,增加一个二位三通电磁滑阀;在电气系统回路,减掉一个交流接触器。这样,可以使油泵电 Our factory SZL double longitudinal steam drum chain boiler, because the pump motor commutation, violent vibration, reverse gear pump, trapped oil elastic coupling damage, pump motor shaft is also easy to break. In order to solve this problem, we have reformed the hydraulic electrical part of the boiler by adding a two-position, three-way solenoid valve to the hydraulic system circuit and subtracting an AC contactor from the electrical system circuit. In this way, you can make the oil pump
