油库输油泵房,由于油蒸气的存在酿成爆炸而引起火灾事故屡见不鲜。究其原因,多是输油泵转轴与泵壳之间的间隙而漏油所致。虽然泵厂已采取了诸如机械密封等装置,但仍未能根绝泵轴滴油。现采用图示的泵轴密封装置漏油回收设施,则可杜绝油蒸气的产生。其结构是在两端交承轴承壳体下部开一个丝孔,装上倒接管,引出塑料软管与阀门连接,再用钢管与真空罐相连。开泵时,开启阀门,泵轴密封装置滴漏的油就可随时吸入真空罐内。同时,在支承壳体上部安装了有机玻璃护罩,是防止泵转甩油而设置的,其外形为“∩”形。倒接管的内径尽可能小(φ1~2mm),其外径以能插入φ8
Oil storage pump room, due to the presence of oil vapor explosion caused by fire accidents are commonplace. The reason, mostly oil pump shaft and the gap between the pump and oil leakage caused. Although the pump plant has taken such as mechanical seals and other devices, but still can not eliminate the pump shaft drip. Now the use of the pump shaft seal leakage oil recovery facilities, you can eliminate the generation of oil vapor. Its structure is in the lower end of the bearing housing at both ends to open a wire hole, fitted with inverted pipe, leading plastic hose and valve connection, and then connected to the vacuum tube with steel. Open the pump, open the valve, pump shaft seal dripping oil can be drawn into the vacuum tank at any time. At the same time, in the upper part of the support housing installed plexiglass shield, is to prevent the pump set off the oil, the shape of “∩” shape. The inner diameter of the inverted pipe is as small as possible (φ1 ~ 2mm), and the outer diameter of the pipe can be inserted into φ8
