1. Start og betjen<\/p>\n

\uff081\uff09 Start den selvansugende pumpe, og v\u00e6r opm\u00e6rksom p\u00e5, om pumpeakslens retning er korrekt.<\/p>\n

\uff082\uff09 V\u00e6r opm\u00e6rksom p\u00e5, om der er unormale lyde og vibrationer under rotation.<\/p>\n

\uff083\uff09 V\u00e6r opm\u00e6rksom p\u00e5 afl\u00e6sningerne af trykm\u00e5leren og vakuumm\u00e5leren. N\u00e5r afl\u00e6sningerne af trykm\u00e5leren og vakuumm\u00e5leren svinger i en periode efter start og derefter viser stabilitet, betyder det, at pumpen er blevet fyldt med v\u00e6ske og er g\u00e5et over til normal infusionsdrift.<\/p>\n

(4) F\u00f8r pumpen g\u00e5r i normal infusionsdrift, dvs. under selvansugningsprocessen, skal man v\u00e6re s\u00e6rlig opm\u00e6rksom p\u00e5 stigningen i vandtemperaturen i pumpen. Hvis denne proces er for lang, og vandtemperaturen i pumpen er for h\u00f8j, skal du stoppe pumpen og kontrollere \u00e5rsagen.<\/p>\n

(5) Hvis temperaturen p\u00e5 v\u00e6sken i pumpen er for h\u00f8j, og det giver problemer med selvansugning, kan du midlertidigt stoppe pumpen, bruge v\u00e6sken i afgangsr\u00f8ret til at str\u00f8mme tilbage i pumpen eller tilf\u00f8je v\u00e6ske direkte til pumpen gennem v\u00e6skeopbevaringsporten p\u00e5 pumpehuset for at afk\u00f8le v\u00e6sken i pumpen og derefter starte den.<\/p>\n

\uff086\uff09 Hvis pumpen vibrerer og larmer under drift, kan det skyldes kavitation. Der er to grunde til kavitation: Den ene er, at indl\u00f8bsr\u00f8rets str\u00f8mningshastighed er for h\u00f8j, og den anden er, at sugeomr\u00e5det er for h\u00f8jt. N\u00e5r flowhastigheden er for h\u00f8j, kan udl\u00f8bsventilen justeres for at \u00f8ge trykm\u00e5lerens afl\u00e6sning. Hvis der er en blokering i indl\u00f8bsr\u00f8ret, skal den fjernes i tide; hvis sugeomr\u00e5det er for h\u00f8jt, kan pumpens installationsh\u00f8jde s\u00e6nkes p\u00e5 passende vis.<\/p>\n

(7) Hvis pumpen af en eller anden grund stoppes under drift og skal genstartes, skal udl\u00f8bsventilen \u00e5bnes lidt (ikke lukkes helt), hvilket bidrager til udledning af gas fra udl\u00f8bsporten under selvansugning og kan sikre, at pumpen starter under en lettere belastning.<\/p>\n

\uff088\uff09 V\u00e6r opm\u00e6rksom p\u00e5 at kontrollere, om r\u00f8rledningssystemet har l\u00e6kage.<\/p>\n

2. Stop pumpen<\/p>\n

\uff081\uff09 Luk f\u00f8rst skydeventilen p\u00e5 udl\u00f8bsr\u00f8ret.<\/p>\n

\uff082\uff09 Stop pumpen.<\/p>\n

\uff083\uff09 I kolde \u00e5rstider skal du dr\u00e6ne v\u00e6sken i pumpehuset og vandet i lejekroppens k\u00f8lerum for at forhindre frysning og revnedannelse af delene.<\/p>\n
