Umbuzo: yeyiphi imiba ekufuneka ithathelwe ingqalelo ekufakeni, ukusetyenziswa kunye nokugcinwa kwevalve yokhuseleko?

A:

Imiba efuna ingqwalasela kufakelo, ukusetyenziswa nokugcinwa kweevalvu zokhuseleko

Ukusebenza okuchanekileyo kwevalve yokhuseleko kubaluleke kakhulu, ngoko ke yiyiphi imiba ekufuneka iqwalaselwe ekufakeni, ukusetyenziswa kunye nokugcinwa kwevalve yokhuseleko?

Umgangatho wevalve yokhuseleko ngokwawo uyimfuneko yokuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo. Nangona kunjalo, ukuba umsebenzisi akayisebenzisi ngokufanelekileyo, i-valve yokhuseleko ayinakusebenza ngokuqhelekileyo, ngoko ke ukufakela kunye nokusetyenziswa kubaluleke kakhulu. Phakathi kweengxaki ezichazwe ngabasebenzisi, ukungaphumeleli kwe-valve yokhuseleko okubangelwa ukufakela okungafanelekanga kunye nokusetyenziswa kwe-akhawunti ye-80%. Oku kufuna ukuba abasebenzisi baphucule ukuqonda kwabo ulwazi lwemveliso yevalvu yokhuseleko kunye nobuchwepheshe kwaye balandele ngokungqongqo iinkcukacha zokusebenza.

Iivalvu zokhuseleko zizixhobo ezichanekileyo zoomatshini kwaye zineemfuno eziphezulu zofakelo nokusetyenziswa kwazo. Kumashishini enkqubo eqhubekayo, emva kokuba isethi yezixhobo zakhiwe, iya kuhamba kwiinkqubo ezininzi ezifana nokuhlanjululwa, ukuxinwa komoya, kunye novavanyo loxinzelelo, kwaye emva koko uthunywe. Impazamo eqhelekileyo eyenziwa ngabasebenzisi kukufaka ivalve yokhuseleko kumbhobho wenkqubo ngexesha lokucoca. Ekubeni i-valve yokukhusela ikwimeko evaliweyo, i-debris ingena kwi-inlet ye-valve yokukhusela ngexesha lokucoca. Ngethuba lovavanyo loxinzelelo, i-valve yokhuseleko igxuma kwaye ibuyele. Ngenxa yenkunkuma xa uhleli, ivalve yokhuseleko iya kusilela.

Ngokwemigangatho yesizwe, la manyathelo alandelayo kufuneka athathwe xa kuhlanjululwa:

1. Ivalve yokhuseleko ivumelekile ukuba ifakwe kumbhobho wenkqubo, kodwa ipleyiti eyimfama kufuneka yongezwe kwindawo yokungena yevalve yokhuseleko ukuyivala.
2. Ngaphandle kokufaka ivalve yokhuseleko, sebenzisa ipleyiti eyimfama ukuvala uqhagamshelo phakathi kwevalve yokhuseleko kunye nombhobho wenkqubo, kwaye ubuyisele ivalve yokhuseleko emva kokuba uvavanyo loxinzelelo lugqityiwe.
3. Ivalve yokhuseleko itshixiwe, kodwa kukho umngcipheko kulo mlinganiselo. Umsebenzisi unokulibala ukuwususa ngenxa yokungakhathali, okubangela ukuba ivalve yokhuseleko ingaphumeleli ukusebenza kakuhle.

Umsebenzi wenkqubo kufuneka uzinzile ngexesha lokusetyenziswa. Ukuba ukuguquguquka koxinzelelo kukhulu kakhulu, kuya kubangela ukuba ivalve yokhuseleko ixhume. Ngokwemigangatho kazwelonke, xa ivalve yokhuseleko itsiba, kufuneka ihlaziywe.

Ukongezelela, iiparitha zobugcisa ezinikezelwa ngumsebenzisi kufuneka zichaneke, kwaye i-medium yesicelo kufuneka ilungiswe. Ngokomzekelo, i-medium kwiiparameters zobugcisa ezinikezelweyo ngumoya, kodwa ukuba i-chlorine ixutywe nayo ngexesha lokusetyenziswa, i-chlorine kunye nomphunga wamanzi uya kudibanisa ukwenza i-hydrochloric acid, eya konakalisa i-valve yokukhusela. Ibangela umhlwa; okanye i-medium kwi-technical parameters enikeziweyo ngamanzi, kodwa eyona nto iphakathi iqulethe igrabile, eya kubangela ukuguga kwivalve yokhuseleko. Ke ngoko, abasebenzisi abanako ukutshintsha iiparameters zenkqubo ngokuthanda. Ukuba utshintsho luyafuneka, kufuneka bahlolisise ukuba i-valve yokukhusela enikezelwa ngumenzi we-valve ifanelekile kwiimeko zokusebenza ezitshintshileyo kunye nokunxibelelana nomenzi ngexesha elifanelekileyo.

Ukuba oku kungasentla kunokusebenza ngokuchanekileyo ngokwemigaqo ebekiweyo, isivalo sokhuseleko kufuneka sivavanywe minyaka le, kwaye umqhubi kufuneka afumane “iSatifikethi soMsebenzi weSixhobo esiKhethekileyo.”
