Indawo yokuvala ivamise ukugqwala, iguguleke, futhi igqokwe yi-medium futhi yonakaliswa kalula ngoba uphawu lusebenza njengokusika nokuxhuma, ukulawula nokusabalalisa, ukuhlukanisa, kanye nokuxuba idivayisi yemidiya esiteshini sevalvu.

Umonakalo ongaphezulu ungavalwa ngezizathu ezimbili: umonakalo owenziwe umuntu kanye nomonakalo wemvelo. ukuklama okubi, ukwakhiwa okubi, ukukhetha okungalungile kwempahla, ukufakwa okungalungile, ukusetshenziswa kabi, nokungakhathalelwa kahle ngezinye zezimbangela zomonakalo owumphumela womsebenzi womuntu. Umonakalo wemvelo ukuguga kwei-valveokwenzeka ngesikhathi sokusebenza okuvamile futhi kuwumphumela wokugqwala okungenakubalekelwa kwendawo kanye nesenzo sokuguguleka endaweni evalayo.

Izizathu zokulimala kwendawo yokuvala zingafingqwa ngale ndlela elandelayo:

1. Ikhwalithi yokucubungula yendawo yokuvala ayilungile.

Izimpawu zayo eziyinhloko amaphutha afana nokuqhekeka, izimbotshana, kanye nokufaka endaweni evalekayo, elethwa ngokunganele kwe-welding engaphezulu kanye nokusebenza kwenqubo yokwelashwa kokushisa kanye nokukhethwa kwemininingwane engafanele. Ukukhetha okungalungile kwempahla kubangele izinga eliphezulu kakhulu noma eliphansi kakhulu lobulukhuni endaweni yokuvala. Ngenxa yokuthi insimbi engaphansi ivuthela phezulu ngesikhathi senqubo yokuvela phezulu, ethambisa ukwakheka kwengxubevange yendawo yokuvala, ukuqina kwendawo yokuvala abulingani futhi ayimelani nokugqwala, kungaba ngokwemvelo noma ngenxa yokwelashwa okungalungile kokushisa. Ngokungangabazeki, kukhona nezinkinga zokuklama kulokhu.

2. Umonakalo olethwa ukukhetha okubi nokusebenza kabi

Ukusebenza okuyinhloko ukuthi ukusikai-valveisetshenziswa njenge-throttlei-valvenokuthi i-valve ayikhethelwa izimo zokusebenza, okuholela ekuvaleni okukhulu kwengcindezi ethile kanye nokuvalwa okushesha kakhulu noma okuxegayo, okuholela ekugugulekeni nasekugugekeni endaweni evalekayo.

Indawo yokuvala izosebenza ngokungajwayelekile ngenxa yokufakwa okungafanele kanye nokugcinwa ngokunganaki, futhi i-valve izosebenza kabi, ilimaze ngaphambi kwesikhathi indawo yokuvala.

3. Ukuwohloka okuphakathi kwamakhemikhali

Uma singekho isizukulwane samanje nge-medium ezungeze indawo yokuvala, i-medium ixhumana ngokuqondile nendawo yokuvala futhi igqwalise. Indawo yokuvala ngasohlangothini lwe-anode izogqwala ngenxa yokugqwala kwe-electrochemical kanye nokuxhumana phakathi kwendawo yokuvala, ukuthintana phakathi kwendawo yokuvala nomzimba ovalayo kanye nomzimba we-valve, umehluko wokugxilisana we-medium, umehluko wokuhlushwa komoyampilo, njll.

4. Ukuguguleka okuphakathi

Kwenzeka lapho okuphakathi kugijima endaweni evaliwe futhi kubangela ukuguga, ukuguguleka, kanye ne-cavitation. Izinhlayiya ezinhle ezintantayo endaweni ephakathi nendawo yokuvala lapho ifinyelela isivinini esithile, okuholela ekulimaleni kwendawo. Umonakalo owenziwe endaweni uphuma kumithombo yezindaba egeleza ngesivinini esiphezulu ekhuhla ngqo indawo yokuvala. Amabhamuza omoya aqhuma futhi athintane nendawo yophawu lapho okuphakathi kuhlangene futhi kuhwamuke kancane, okuholela ekulimaleni kwendawo. Indawo evalekayo izoguguleka kakhulu ngenxa yokuguguleka kwenhlabathi kanye nesenzo sokugqwala kwamakhemikhali.

5. Ukulimala kwemishini

Ukuklwebheka, imihuzuko, ukuminyanisa, nomunye umonakalo endaweni yokuvala kuyokwenzeka kuyo yonke inqubo yokuvula nokuvala. Ngaphansi kwethonya lokushisa eliphezulu nokucindezela okukhulu, ama-athomu angena omunye komunye phakathi kwezindawo ezimbili zokuvala, okubangela ukwenzeka kokunamathela. I-adhesion iklebhuka kalula lapho izindawo ezimbili zokuvala zihamba ngokuhlobene. Lesi simo cishe singenzeka uma indawo evalekayo inobunzima obungaphezulu obungaphezulu. Indawo evalekayo izoguga kancane noma ihlehle ngenxa yokulimala kwediski ye-valve nokumpintsha kwendawo evalayo lapho ibuyela esihlalweni sevalvu ngesikhathi sokuvala.

6. Ukuguga

Indawo yokuvala izokhathala ngokuhamba kwesikhathi ngenxa yesenzo sokushintshana kwemithwalo, okuholela ekuthuthukisweni kwemifantu kanye nezingqimba zokuxebuka. Ngemuva kokusetshenziswa isikhathi eside, irabha namapulasitiki ajwayele ukuguga, okuphazamisa ukusebenza.

Kuyacaca ocwaningweni lwezimbangela zomonakalo owenziwe ngenhla ukuthi ukukhetha izinto ezifanele zokuvala, izakhiwo zokuvala ezifanele, nezindlela zokucubungula kubalulekile ukuze kwandiswe izinga nempilo yesevisi yendawo yokuvala kumavalvu.
