西安重型机械研究所和成都611研究所最近研制成功了 PY 型水环蒸汽喷射泵。共有两种型号,其技术指标是:型号 PY11000 PY25000工作蒸汽压力(公斤/厘米~2) 8 8蒸汽耗量(吨/小时) 1.5 2.5冷却水量(吨/小时) 100 150冷却水温(℃) 30 30耗电功率(千瓦) 70 70在粗低真空范围内,PY 泵兼有水环真空泵的低真空度(200～760托),大抽气量和蒸汽喷射泵较高真空度(10~(-2)～30托)大抽气量的特点。并在30～200托弥补了两者的不足。与水
Xi’an Heavy Machinery Institute and Institute of Chengdu 611 recently developed a PY-type water ring steam jet pump. There are two models, the technical indicators are: Model PY11000 PY25000 Working steam pressure (kg / cm ~ 2) 8 8 Steam consumption (tons / hour) 1.5 2.5 Cooling water (tons / hour) 100 150 Cooling water temperature 30 Power Consumption (kW) 70 70 Low vacuum (200 ~ 760 Torr), high suction capacity and high vacuum degree of steam jet pump (10 ~ (- 2) ~ 30 Torr) large amount of exhaust characteristics. And make up for both the deficiencies in 30 ~ 200 Torr. with water
