1. Pornirea \u0219i func\u021bionarea<\/p>\n

\uff081\uff09porni\u021bi pompa autoamorsant\u0103 \u0219i verifica\u021bi dac\u0103 direc\u021bia arborelui pompei este corect\u0103.<\/p>\n

\uff082\uff09Privi\u021bi cu aten\u021bie dac\u0103 exist\u0103 sunete \u0219i vibra\u021bii anormale \u00een timpul rota\u021biei.<\/p>\n

\uff083\uff09Presta\u021bi aten\u021bie citirilor manometrului \u0219i vacuumometrului. Dup\u0103 pornire, atunci c\u00e2nd valorile manometrului \u0219i ale manometrului de vid fluctueaz\u0103 pentru o perioad\u0103 de timp \u0219i apoi indic\u0103 stabilitate, \u00eenseamn\u0103 c\u0103 pompa a fost umplut\u0103 cu lichid \u0219i a intrat \u00een func\u021bionare normal\u0103 de perfuzie.<\/p>\n

\uff084\uff09\u00cenainte ca pompa s\u0103 intre \u00een func\u021bionarea normal\u0103 de perfuzie, adic\u0103 \u00een timpul procesului de autoamorsare, trebuie acordat\u0103 o aten\u021bie deosebit\u0103 cre\u0219terii temperaturii apei din pomp\u0103. Dac\u0103 acest proces dureaz\u0103 prea mult \u0219i temperatura apei din pomp\u0103 este prea ridicat\u0103, opri\u021bi pompa \u0219i verifica\u021bi cauza.<\/p>\n

\uff085\uff09Dac\u0103 temperatura lichidului din pomp\u0103 este prea ridicat\u0103 \u0219i provoac\u0103 dificult\u0103\u021bi \u00een autoamorsare, pute\u021bi opri temporar pompa, pute\u021bi utiliza lichidul din conducta de refulare pentru a curge \u00eenapoi \u00een pomp\u0103 sau pute\u021bi ad\u0103uga lichid direct \u00een pomp\u0103 prin orificiul de stocare a lichidului de pe corpul pompei pentru a r\u0103ci lichidul din pomp\u0103 \u0219i apoi o pute\u021bi porni.<\/p>\n

\uff086\uff09Dac\u0103 pompa vibreaz\u0103 \u0219i scoate zgomote \u00een timpul func\u021bion\u0103rii, aceasta poate fi cauzat\u0103 de cavita\u021bie. Exist\u0103 dou\u0103 motive pentru cavita\u021bie: unul este c\u0103 debitul conductei de admisie este prea mare, iar cel\u0103lalt este c\u0103 intervalul de aspira\u021bie este prea mare. Atunci c\u00e2nd debitul este prea mare, supapa de control a ie\u0219irii poate fi reglat\u0103 pentru a cre\u0219te citirea manometrului. Dac\u0103 exist\u0103 un blocaj \u00een conducta de admisie, acesta trebuie eliminat la timp; dac\u0103 intervalul de aspira\u021bie este prea mare, \u00een\u0103l\u021bimea de instalare a pompei poate fi redus\u0103 corespunz\u0103tor.<\/p>\n

\uff087\uff09Dac\u0103 pompa este oprit\u0103 din anumite motive \u00een timpul func\u021bion\u0103rii \u0219i trebuie repornit\u0103, supapa de control a ie\u0219irii trebuie s\u0103 fie u\u0219or deschis\u0103 (nu complet \u00eenchis\u0103), ceea ce favorizeaz\u0103 evacuarea gazului din orificiul de evacuare \u00een timpul autoamors\u0103rii \u0219i poate asigura pornirea pompei cu o sarcin\u0103 mai u\u0219oar\u0103.<\/p>\n

\uff088\uff09Ajuta\u021bi aten\u021bie pentru a verifica dac\u0103 sistemul de conducte are scurgeri.<\/p>\n

2. Opri\u021bi pompa<\/p>\n

\uff081\uff09First, \u00eenchide\u021bi supapa de \u00eenchidere de pe conducta de evacuare.<\/p>\n

\uff082\uff09 Opri\u021bi pompa.<\/p>\n

\uff083\uff09\u00cen sezoanele reci, scurge\u021bi lichidul din corpul pompei \u0219i apa din camera de r\u0103cire a corpului rulmentului pentru a preveni \u00eenghe\u021barea \u0219i fisurarea pieselor.<\/p>\n
