冷冻冰机的工作过程是依据物理转换:(压力×体积)/温度=常数(即p1v1/t1=p2v2/t2)使气氨转为液氨的物理工艺过程。所以气氨的压力、温度是工艺控制的重要参数。
生产中将压力低于2kg/m3的气氨通过系统的气氨总管进入进口处的氨分离器,分离出液氨雾滴,滤去液氨雾滴的气氨流过系统管进入压缩机组的吸气过滤器,再通过过滤器中的过滤网滤去气氨夹带的小杂物(其中吸气过滤器设有温度计指示吸气温度,并由一截止阀连接吸气压力表来指示吸气压力)。干净的气氨进入螺杆压缩机进行压缩升压(即气压由0.3mpa上升至1.57mpa),压缩后的气体至排气口排出。在压缩机运转中,油泵向压缩机内喷入大约占体积流量0.5~1%的润滑油,这部分润滑油起着冷却、密封、润滑的作用,此时要求油喷入的压力必须大于压缩机内气氨的压力,保证润滑油顺利喷入,这里的油气压差检测点为重要参数。这些润滑油随排气排入油分离器,进行油分离,油分离器中装有一安全阀,作用是当分离器内的压力过大,则通过安全阀放空。此后系统分为气路过程和油路过程。

从气路过程来看:经过油分离的氨气以温度为60~70℃、1.35~1.40mpa的压力进入冷凝器冷凝成液氨,液氨进入液氨收集器;从油路过程来看:在油分离器中分离出的油经过油冷却器,冷却后的油经过逆止阀(只能单方向流通)进入到油粗过滤器,滤去铁屑等大颗粒杂质后到喷油油泵进口,由油泵升压后,再经油精过滤器进一步过滤后回流到喷油总管进入压缩机。油泵并接了附线阀来调节油泵压力,油精过滤器接有压力表(正常时压力值应较小≤0.07mpa,压力值较大时说明过滤器中滤网被堵,需清理),其基本工艺流程框图如图1所示:
