Amagama 'ukugungxula' kunye 'nokucima' often seem to be confused or misused when discussing seal support schemes for >iimpompo ezinodaka. Njengoko iikhonsepthi zekhatriji yokutywina yomatshini kunye nekhatriji yokutywina egcweleyo yahluke kancinane, ndiza kuzixoxa ngokwahlukeneyo kwaye ngokulandelelana.

Mechanical amatywina

Inkqubo yokugungxulwa kwetywina koomatshini ilula kakhulu. Ifuna ukuba ulwelo olucacileyo/ olucocekileyo (ludla ngokuba ngamanzi) lungeniswe kwisithuba esiphakathi kwetywina lokwenyani kunye nesithintelo se-impeller side outlet. I-flushing fluid ifakwe kuxinzelelo oluphezulu kunoxinzelelo lokupompa, ngaloo ndlela iqinisekisa ukuphuma kakuhle / ukugungxulwa kwesitywina somatshini kunye nendawo yokusebenza ecocekileyo.
Ukugungxula kuchazwa “njengolwelo olungeniswa kumngxunya wetywina kwicala lolwelo lwenkqubo, kufutshane nobuso betywina, kwaye luqhele ukusetyenziswa ukupholisa nokuthambisa ubuso betywina.

When flushing is required, the >umboneleli wempompo eludaka icebisa i-API Option 32 yolungiselelo lwemibhobho etywiniweyo njengoko ifaneleke ngakumbi kwiinkonzo eziqulathe izinto eziqinileyo okanye ezingcolisayo ezinokonakalisa ubuso betywina xa ijikeleziswa kwakhona kwindawo yokugungxula.
Ulwelo olucacileyo olucocekileyo olunikezelwe kumthombo wangaphandle ludla ngokusetyenziswa oluhanjiswa kwindawo yokutywina ephambili kwicala lolwelo lwenkqubo yokutywinwa. Ngokusebenzisa i-gap throat bushing, ibhokisi yokuhlohla inokuphinda icinezelwe ukuya kuxinzelelo oluphezulu, ukuqinisekisa ukuba ulwelo olugungxulwayo aludanyazi kubuso betywina.

Isicwangciso sokucima, njengoko igama libonisa, lenzelwe ukucima okanye ukupholisa isitywina. Ngokuqhelekileyo isetyenziswa ukuba ixesha elifutshane lokubaleka lilindelekile. Njengoko kubonisiwe ngezantsi, ulwelo lungeniswa kwindawo ephakathi kobuso bomva wetywina kunye nokuvala ngokusondeleyo kokuphuma kwicala lokuqhuba lempompo.
Ihlala isetyenziswa ukuba ixesha elifutshane lokubamba elomileyo lilindelwe. Ulwelo lungeniswa kwindawo ephakathi komva wobuso betywina kunye nendawo yokuphuma eqinileyo kwicala lokuqhuba lempompo eludaka.

Ukucima kuchazwa "njengokuqaliswa kolwelo olungathathi hlangothi (ngokuqhelekileyo amanzi okanye umphunga) kwicala le-atmospheric yetywina ukuthintela ukubunjwa kwezinto eziqinileyo ezinokuphazamisa ukuhamba okanye ukusetyenziselwa ezinye iinjongo.
Amanye amatywina okucima acetywe ukuba athathe indawo yesithintelo esibambekayo ngotywino lwesibini kunye nendawo yokuphuma ephezulu enokufakwa umbhobho ukuze ibambe ulwelo olusetyenzisiweyo lokucima nokulukhupha kwindibano ejikelezayo. Nangona kunjalo umgaqo uyafana, sizama ukupholisa itywina kunokuligungxula nangayiphi na indlela.

Isilumkiso: Impazamo eqhelekileyo kukucinezela ibhokisi ngokugqithisileyo kwaye wonakalise itywina elibiza oomatshini.

Ukupakisha ibhokisi yokutywina

The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences.  The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.

Ukusuka kwindawo yokusebenza, ibhokisi yokuhlohla yahlukile njengoko ifuna ukuvuza okuthile ukuze kuqinisekiswe ukuthambisa kunye nokuthintela ukwanda kobushushu. Ibhokisi yokutywina yoomatshini kufuneka ingavuzi.
Umgaqo wobhontsi wokuseta uxinzelelo lwamanzi uyafana xa usebenzisa ibhokisi yokupakisha, nokuba uyagungxulwa. Uxinzelelo lokuvala impompo yodaka kunye ne-10% okanye kunye ne-20 psi, nokuba yeyiphi enkulu. Nangona kunjalo, izinga lokuhamba libekwe ngokwahlukileyo.

Ngeshedyuli eqhelekileyo yokugungxula, ukuhamba ngokuqhelekileyo kulungelelaniswa ngokucinezela ukupakisha de kube amaconsi ambalwa amanzi abonwa evuza kwiitywina kwicala lokuqhuba. Kwishedyuli yokucima isantya sokuhamba sisetwa ngokulungelelanisa i-valve yokungena, ngelixa i-valve isetyenziselwa kwicala lokukhupha ukugcina uxinzelelo oluchanekileyo lwetanki. Ukuba amanzi aphuma kwibhokisi yokutywina ashushu kakhulu, izinga lokuhamba liyenyuka de amanzi aphumayo aphole, ngelixa ugcina uxinzelelo oluchanekileyo lwebhokisi.

I hope this short blog has helped to clear up some of the confusion about the seal flush programme. Please always refer to the pump manual for specific details. If there are still questions, welcome to >Qhagamshelana nathi namhlanje.
