SDB系列水冷挡板安装在油扩散真空泵的入口与高真空阀之间，用来阻挡油扩散真空泵中的油蒸汽，降低泵的返油率，起到清洁真空室的作用。本公司生产的水冷挡板采用百叶窗式（A1、A2型）和锥塔形（B1、B2型冷剂为水或氟里昂两用），捕集面积大，结构紧凑，冷却效果好。B1、B2型采用不锈钢拉伸制造工艺，减少焊缝，增加强度，降低放气量。订货注意：请选定型式A1、A2、B1或B2技术数据TECHNICALDATA项目Item型号Type漏率LeakRatePa·L/s流导ConductanceL/s净重NetWeightkgA1A2B1B2A1A2B1B2SDB-1001.3×10-51601601901406.37.31520SDB-16074074085070010.5132328SDB-200940940113085012.615.93550SDB-250120012001500108017.5204265SDB-300190019002280171020306080SDB-320200020002400180028396590SDB-4003400340040803060324775100SDB-5005000500060004500416090120SDB-6007100710085206400549095130SDB-630780078009360702062101100135SDB-8001250012500150001125080140110150SDB-9001720017200182401368098179125165SDB-100019600196002352017640117221135180SDB-1200223002230026760200700162319185250SDB-140038000380004500033800220380245308SDB-160050200502005900044200270430300360外形尺寸与安装尺寸OUTLINE＆INSTALATIONDIMENSI***(mm)项目Item型号TypeDND1D2D3D4D5n-dn-MHA1A2B1B2SDB-1001001451701001451704-Ф124-M1050100100150SDB-1601602002251602002258-Ф118-M1050120120180SDB-2002002502752002502758-Ф128-M1050135135200SDB-25025031033525031033512-Ф1112-M1050135135200SDB-3003003503803003503808-Ф148-M1250145145220SDB-32032039542532039542512-Ф1412-M1250145145220SDB-4004004655004004655008-Ф188-M1650160160250SDB-50050056560050056560012-Ф1812-M1650160160250SDB-60060067071060067071012-Ф2112-M1850180180275SDB-63063072075063072075020-Ф1420-M1250180180275SDB-80080088092080088092020-Ф2120-M1850200200300SDB-90090097810609001060106028-Ф2228-M1850200200300SDB-100010001090114010001090114024-Ф2324-M2050200200300SDB-120012001310136012001310136028-Ф2528-M2250210210320SDB-140014001550160014001550160044-Ф2344-M2050260260320SDB-160016001760180016001760180044-Ф2344-M2050260260320)
