Grundl\u00e6ggende data for valg af pumpe: <\/span><\/p>\n

1, mediets egenskaber: mediets navn, v\u00e6gtfylde, viskositet, korrosion, toksicitet osv. <\/span><\/p>\n

2, partikeldiameteren og indholdet af det faste stof i mediet. <\/span><\/p>\n

3, medium temperatur: (\u2103) <\/span><\/p>\n

4, kan det n\u00f8dvendige flow af generelle industripumper i processen ignorere l\u00e6kagen i r\u00f8rledningssystemet, men skal overveje indvirkningen af proces\u00e6ndringer p\u00e5 flowet.<\/span> Hvis landbrugspumper bruger \u00e5bne kanaler til at transportere vand, skal de ogs\u00e5 tage h\u00f8jde for m\u00e6ngden af l\u00e6kage og fordampning. <\/span><\/span><\/p>\n

5, tryk: sugetanktryk, afl\u00f8bstankens tryk, trykfald i r\u00f8rledningssystemet (hovedtab). <\/span><\/p>\n

6. Data om r\u00f8rledningssystemet (r\u00f8rdiameter, l\u00e6ngde, type og antal r\u00f8rtilbeh\u00f8r, geometrisk h\u00f8jde fra sugebassin til trykbassin osv.) <\/span><\/p>\n

7, pumpemateriale og t\u00e6tningsform <\/span><\/p>\n

8, i henhold til flow, hoved for at v\u00e6lge den passende brug af pumpeomr\u00e5det og strukturen <\/span><\/p>\n

9, i henhold til installationsstedet for at v\u00e6lge pumpeform (lodret, vandret, transmissionsform) <\/span><\/p>\n

10, v\u00e6lg drivkraft i henhold til str\u00f8mforsyningen <\/span><\/p>\n

11, v\u00e6lg pumpens struktur i henhold til brugen (rentvandspumpe, brandpumpe, spildevandspumpe osv.) <\/span><\/p>\n

Bestemmelse af flow: <\/span><\/p>\n

1, hvis produktionsprocessen har givet et lille, normalt, stort flow, skal overvejes i henhold til det store flow. <\/span><\/p>\n

2, hvis kun den normale str\u00f8mningshastighed er givet i produktionsprocessen, skal der tages h\u00f8jde for en vis margin.<\/span> For pumper med stort flow og lav l\u00f8fteh\u00f8jde med ns>100 er flowmargenen 5%, for pumper med lille flow og h\u00f8j l\u00f8fteh\u00f8jde med ns<50 er flowmargenen 10%, for pumper med 50\u2264ns\u2264100 er flowmargenen ogs\u00e5 5%, og for pumper med d\u00e5rlig kvalitet og d\u00e5rlige driftsforhold b\u00f8r flowmargenen v\u00e6re 10%. <\/span><\/span><\/p>\n

3, hvis grunddataene kun vedr\u00f8rer v\u00e6gtflowet, skal de konverteres til volumenflow. <\/span><\/p>\n
