SIHI真空泵中国总代理(福斯FLOWSERVE集团) 2024-05-04 22:21:03 0 0 SIHI真空泵中国总代理(福斯FLOWSERVE集团) 产地中国上海,德国品牌,美国福斯FLOWSERVE集团总公司全资收购。 Liquid ring vacuum pumps 液环式真空泵in close coupled design 机泵同轴设计LEMC 25, 50, 90, 125, 150, 250PRESSURE RANGE:入口压力范围: 33 – 1013 mbarSUCTION VOLUME:入口流量: 24 - 280 m³/hCONSTRUCTION TYPE结构型式SIHI liquid ring vacuum pumps are displacement pumps ofuncomplicated and robust construction with the following particularfeatures:SIHI 液环式真空泵是结构简单使用可靠的容积变化式泵,具有如下特点:nearly isothermal compression几乎等温压缩,oil-free, as no lubrication in the working chambertherefore non-polluting在工作腔内无需润滑,因而无油,纯净Capable of handling of nearly all gases and vapours可处理几乎所有的气体和蒸汽small quantities of entrained liquid can be handled可处理少量的夹带液体easy maintenance and reliable operation易维护,高可靠性low noise and nearly free from vibration低噪音,几乎无振动wide choice of materials, therefore applicable nearlyeverywhere广泛的材质选择,基本上可用于所有场合shaft not in contact with the medium轴不接触介质protection against cavitation as standard气蚀保护作为标准配置incorporated dirt drain一体式排污no metallic contact of the rotating parts旋转部件没有金属接触SIHI liquid ring vacuum pumps LEMC are single-stageSIHI LEMC 系列液环式真空泵是单级泵。 APPLICATION应用Handling and exhausting of dry and humid gases; entrained liquid canbe handled during normal duty. The pumps are applied in all fieldswhere a pressure of 33 to 900 mbar must be generated干气和湿气的处理和抽除;正常条件下可处理夹带的液体. 此真空泵可用于所有需要33 mbar到900 mbar的场合。NOTE 泵运转期间需连续不断地补充工作液(通常为水),以带走气体压缩而产生的热量和补充部分随气体排出的工作液。此部分工作液可在汽液分离器中与气体分开(请见样本附件部分),以重新利用。泵可按需要配备一个连接,以保证在运转条件下连续地排放被污染的工作液。The direction of rotation is clockwise, when looking from themotor towards the pump.从泵的驱动端看,泵的旋转方向为顺时针。2GENERAL TECHNICAL DATA 常规技术数据Pump type泵型号 Unit单位LEMC25LEMC50LEMC90LEMC125LEMC150LEMC250Synchronous speed同步转速 50 Hz rpm 3000 1500Max. compression over atmospheric pressure较大背压 bar 0,3Max. admissible pressure difference允许较大压差 bar 1,1Test pressure above atmospheric pressure水压试验(表压) bar 1 1 3 3 3 3Moment of inertia of the rotating pump parts and water filling满水时转动部件的惯性力矩 kg . m² 0,003 0,0095 0,035 0,053 0,069 0,097Sound pressure level at a suction pressure of 80 mbar在80mbar 入口压力下的噪音 dB (A) 68 69 65Dry gasMax. gas temperature 干气 °C 200较大吸气温度Saturated gas饱和气 °C 100Service liquid 工作液max. recommended temperature for water as working liquid工作液为水的较大推荐温度 °C 40max. admissible temperature for other suitable working liquids对其他适合的工作液较大允许温度 °C 80max. kinematic viscosity较大动粘度 mm²/s 4max. density较大密度 kg/m³ 1200volume up to shaft level到轴中心线的容积 liter 0.3 0.4 2.4 2.8 3.2 4.0The combination of several limiting values is not admissible.不允许将几种较限值同时选择Material design 材料设计 Item 0K 0E位号Component零件 LEMC 25/50 LEMC 90/125/150 LEMC 25010.10 Casing泵盖10.90 Central body中间体13.70 Guide disc导流盘0.602523.50 Vane wheel impeller叶轮 1.4301 1.4408XBPFF GBVGG EBPFFCeramic 陶瓷 Cr-Ni-St 铬钢 Cr-Ni-St 铬钢Carbon 石墨 Carbon 石墨 Carbon 石墨Perbunan 丁苯橡胶 Viton 氟橡胶 Perbunan 丁苯橡胶Mechanical sealMaterial option 1机械密封材料选择1Cr-Ni-St 铬钢 Cr-Ni-Mo-St 铬镍钼钢 Cr-Ni-St 铬钢GBMGGCr-Ni-Mo-St 铬镍钼钢Carbon 石墨Viton PTFE encapsulated 氟橡胶外包裹聚四氟乙烯43.30Mechanical sealMaterial option 2机械密封材料选择2Not available 不提供Cr-Ni-Mo-St 铬镍钼钢PTFE75.40 Valve balls阀球 聚四氟乙烯 收藏(0)
