1、概述我厂尿素生产系统是我国自行设计、制造的第一套中型尿素生产装置,所用高压液氨泵是在氨生产用铜液泵基础上的试制产品,存在一些问题,不能满足生产需要,为此我们对氨泵进行了改造。高压液氨泵技术特性: 型号卧式三联柱塞泵;流量Q=20m~3/hr;进液压力P_1=18kgf/cm~2;排液压力P_2=225kgf/cm~2;柱塞直径d=82mm;行程
1. Overview Our urea production system is the first set of medium-sized urea production equipment designed and manufactured by our country. The high-pressure liquid ammonia pump used is a prototype product based on copper liquid pump for ammonia production. There are some problems that can not meet the production needs , For which we have to transform the ammonia pump. High pressure liquid ammonia pump technical characteristics: Model horizontal triple piston pump; flow Q = 20m ~ 3 / hr; inlet pressure P_1 = 18kgf / cm ~ 2; discharge pressure P_2 = 225kgf / cm ~ 2; plunger diameter d = 82mm; travel
