***ITH PUMP SQ-HH
所有标准型号SQ系列的***泵入口端和出口端有3/4”F.N.P.T.和5/8”驱动轴。由于压差超过150P.S.I.D.,1英寸驱动轴被推荐。这个型号强烈的推荐大型的机械或旋转密封轴是必需的,低噪音标准很重要。推荐的***大压差是800P.S.I.D.,液体粘度500S.S.U.以上。每个型号内置旁通阀与外部方向相连接,长期设置在90P.S.I.D.。由于压差超过这个数字,阀出口向左插入,外部旁通阀安装在泵出口附近的球座上。大多数泵直接安装到小型C-框架马达上,如下所示。像这种情况,泵端的部件被支撑必须通过与另一端的底座接触或适当地通过支架焊接。当泵的运行速度慢于直接驱动速度时,底座安装支架也是可以的,带有传送带或减速齿轮部件。AllstandardmodelSQ-Sreies***ithpumpsh***e3/4”F.N.P.T.inletandoutletports,anda5/8”driveshaft.Fordifferentialpressureinexcessof150P.S.I.D.,theone-inchdriveshaftisrecommended.Modelsshownarehighlyrecommendedwherealargemechanicalorrotaryshaftsealisrequired,andlownoiselevelsareimportant.Maximumrecommendeddifferentialpressureis800P.S.I.D.onliquidsabove500S.S.U.viscosity.Eachmodelhasabuilt-ininternalbypassvalvewhichmustbeconnectedwithanexternalline,andispermanentlysetat90P.S.I.D..Fordifferentialpressuresinexcessofthisfigure,thevalveoutletcanbeleftplugged,andanexternalbypassvalveinstalledinateenearthepumpoutlet.Mostpumpsaredirectlymountedto***allC-Framemotorsasshown,suchcases,thepumpendoftheassemblymustbesupportedbyeithercontactingthebase,orbymeansofasupportblockweldedinplace.Footmountingbracketsare***ailablealso,whenthepumpmustberunslowerthandirect-drivespeedsallow,withbeltorgear-reductionassembly.)
