我站是一九八○年开始使用立式内循环BAB—1型屏蔽氨泵的。由于原抽气管和放油管设置的位置不当,完全失去作用。多年来深受“气蚀”、“积油”之害,给操作和管理,带来很大麻烦。为了彻底摆脱这种局面,一九八二年开始,经过几年的论证和准备,于一九八七年底,对所有六台屏蔽泵全部进行了革新,具体措施如下: 一、在立式屏蔽泵的上端盖法兰,焊接一个抽气管。(取消玻璃窥视镜,电机的正反转由排出压力判断)。停泵其间和运行中产生的气体以及由于库温波动产生的“气体”,
I started to use vertical internal circulation type BAB-1 shield ammonia pump in 1980. As the original exhaust pipe and drain pipe set in the wrong place, completely lost its effect. Over the years by the “cavitation”, “oil accumulation” of the harm to the operation and management, brought great trouble. In order to completely get rid of this situation, all six shielding pumps were completely renovated at the end of 1987 after several years of demonstration and preparation starting from 1982. The specific measures are as follows: 1. In vertical shielding Pump upper cover flange, welding a suction pipe. (Cancel glass goggles, the positive and negative motor discharge pressure judgment). Stop the gas during operation and during operation, and the “gas” generated by the fluctuation of the reservoir temperature,
