该系列罗茨泵原可作为增压泵使用，但不能直接地把气体排到大气中去，其前级泵可用滑阀泵或旋片泵、水环泵、油环泵等真空泵。本系列罗茨泵的主要特点有：●极限真空度高，用双级滑阀泵作前级泵时，极限真空可进入10-5托。●本身配带溢流阀起自动保护作用。●泵腔内无互相滑动的零件，因此无需用油润滑。●转动部件作过细心的平衡，因此连接平稳、噪音低。●泵的传动采用可靠的消结构，因此可在高压差下长期工作。●在各种真空炉、真空镀膜机、真***装、真空冶炼、真空干燥、真空浸渍、航空航天、高真空模拟试验、太阳能电池以及其他真空作业上广泛地应用。●尤其在金属镁和海绵钛行业应用更为广泛。TheseriesZJPRootsvacuumpumpcanbeusedasboosterscombinedwithabackingpumpsuchasarotarypistonorarotaryvanevacuumpump.Oraliquidringvacuumpump.Buttheycannotbeusedtoexhaustgasdirectlytoatmosphere.TheseriesZJPRootspumpsarehighinultimatepressure（Withadoublestagerotarypistonpumpitsbackingpump.Arootspumpcanattainanultimatepressureof10-4hpa）Theirinherentoverflowvalveplayauto-protectiverole.Lubricationisunnecessaryasthereisnocontactbetweenrotors，rotorandhousing.Therobustdriveofthepumpandoperatingpartsbalancedcarefullypermitthatthepumpbestableoperatedcontinuouslyundertheconditionofhighpressuredifferential.TheseriesZJProotspumpalsoh***eafeatureoflowernoise.Itwidelyusedforvacuumfurnace,vacuumcoating,vacuumpacking,vacuummetallurgical,vacuumdrying,***iationaerospace、highvacuumimitationexperiment、solarpowerenergybatteryandothervacuumworkwidelyused.ItwidelyusedforTitaniumSpongeMagnesiummetal.技术数据TECHNICALDATA项目Item极限压力UltimatePressure抽气速率PumpingSpeedL/S溢流阀压差Pressurereliefvalve进气口径InletDiametermm排气口径OutletDiametermm电机功率MotorPowerKW冷却水量CoolingwaterKG/h推荐配用前级泵RecommendofBackingVacuumPump型号TypePaTorrZJP-705×10-23.75×10-4704×10380501.1—2H-15ZJP-1501501001002.2202H-152H-30AZJP-3003001501504252H-30A2H-70AZJP-6006002.7×1032002007.5302H-70AZJP-120012002502001135ZJ-300H-70BZJP-250025003203202240ZJ-600H-150外形尺寸与安装尺寸OUTLINEINSTALATIONDIMENSI***(mm)代号Code型号TypeZJP-70ZJP-150ZJP-300ZJP-600ZJP-1200ZJP-2500A166580600760950830A1838383838383B300489470690730810B1—275285375386400B2162320305462.5520590B3223027293035B4308865128130130H286510475730760750H1278475450672.5700705H217903069.58590H3—190145234.5235220L8278851140140016101630L1270297330405470600L21886206408121000920D180100150200250320Da1145170220275335425Db1125145195250300425n-M14-M84-M108-M108-M108-M1212-M12D250100150200200250Da2110170220275275335Db290145195250250310n-M24-M84-M108-M108-M108-M1012-M10)
