Umphezulu wokutywina udla ngokugqwala, ukhukuliswe, kwaye unxitywe liphakathi kwaye wonakaliswe ngokulula ngenxa yokuba itywina lisebenza njengokusika nokudibanisa, ukulawula nokusasaza, ukwahlula, kunye nesixhobo sokuxuba kumajelo eendaba kumjelo wevalve.

Umonakalo womphezulu unokutywinwa ngenxa yezizathu ezibini: umonakalo owenziwe ngumntu kunye nomonakalo wendalo.uyilo olubi, ukwenziwa kakubi, ukukhetha izinto ezingafanelekanga, ukufakela okungafanelekanga, ukusetyenziswa kakubi, kunye nokugcinwa kakubi zezinye zezinto ezibangela umonakalo osisiphumo somsebenzi womntu.Umonakalo wendalo kukunxiba kwiivalveolwenzeka ngexesha lokusebenza okuqhelekileyo kwaye sisiphumo somhlwa ongenakubaleka kunye nesenzo sokhukuliseko kumphezulu wokutywina.

Izizathu zokonakaliswa komphezulu wokutywina zingashwankathelwa ngolu hlobo lulandelayo:

1. Umgangatho wokusetyenzwa komphezulu wokutywina usezantsi.

Iimpawu eziphambili zalo ziziphene ezifana nokuqhekeka, ii-pores, kunye nokufakwa kwindawo yokutywinwa, eziziswa ngokungafanelekanga kwe-welding ye-surfacing kunye nokusebenza kwenkqubo yokushisa ukushisa kunye nokukhethwa kwenkcazo engafanelekanga.Ukukhethwa kwezinto ezingalunganga kubangele umgangatho ophezulu kakhulu okanye ophantsi kakhulu wobunzima kumphezulu wokutywina.Ngenxa yokuba isinyithi esisezantsi sivuthelwa phezulu ngexesha lenkqubo yokujonga phezulu, ethi idibanise i-alloy surface yokutywina, ubulukhuni bomphezulu wokutywina abulingani kwaye abukwazi ukumelana nomhlwa, mhlawumbi ngokwendalo okanye ngenxa yonyango olungachanekanga lobushushu.Ngokungathandabuzekiyo, kukwakho iingxaki zoyilo kule nto.

2. Umonakalo owenziwe kukhetho olubi kunye nokusebenza kakubi

Umsebenzi omkhulu kukuba ukunqunyulwaivalveisetyenziswa njenge throttleivalvekunye nokuba ivalve ayikhethwanga kwiimeko zokusebenza, okukhokelela ekuvaleni ngokugqithiseleyo uxinzelelo oluthile kunye nokuvalwa ngokukhawuleza okanye ukuyekelela, okukhokelela kukhukuliseko kunye nokuguga kumphezulu wokutywina.

Umphezulu wokutywina uya kusebenza ngokungaqhelekanga ngenxa yofakelo olungafanelekanga kunye nokugcinwa ngokungakhathali, kwaye i-valve iya kusebenza ngokugula, yonakalise kwangaphambi kwexesha indawo yokutywina.

3. Ukonakala okuphakathi kweekhemikhali

Xa kungekho sizukulwana sangoku ngokujikeleza indawo yokutywina, i-medium isebenzisana ngokuthe ngqo nomphezulu wokutywina kwaye uyidle.Umphezulu wokutywina kwicala le-anode uya kugqwala ngenxa ye-electrochemical corrosion kunye nokunxibelelana phakathi kwendawo yokutywina, unxibelelwano phakathi komphezulu wokutywina kunye nomzimba wokuvala kunye nomzimba wevalvu, umahluko wokuxinana kwendawo ephakathi, umahluko wokuxinana kweoksijini, njl.

4. Ukhukuliseko oluphakathi

Kwenzeka xa i-medium ihamba ngaphesheya kwendawo yokutywinwa kwaye ibangele ukuguga, ukukhukuliseka, kunye ne-cavitation.Amasuntswana amahle adadayo kwi-medium hit kunye nomphezulu wokutywina xa ifikelela kwisantya esithile, okukhokelela kumonakalo wendawo.Iziphumo zomonakalo wendawo ukusuka kwi-high-speed-flowing media ekhuhla ngokuthe ngqo indawo yokutywina.Amaqamza omoya agqabhuke kwaye anxibelelane nomphezulu wokutywina xa i-medium idityanisiwe kwaye ingumphunga ngokuyinxenye, okukhokelela kumonakalo wendawo.Umphezulu wokutywina uya kukhukuliseka kanobom ngenxa yokhukuliseko lwale ndlela kunye nenye intshukumo yokuhlwa kwekhemikhali.

5. Ukwenzakala koomatshini

Imikrwelo, ukugruzuka, ukucudisa, kunye nomnye umonakalo kumphezulu wokutywina kuya kwenzeka kuyo yonke inkqubo yokuvula nokuvalwa.Ngaphantsi kwefuthe lobushushu obuphezulu kunye noxinzelelo oluphezulu, ii-athomu zingena omnye komnye phakathi kweendawo ezimbini zokutywina, ezibangela into yokubambelela.I-adhesion ikrazuka ngokulula xa iindawo ezimbini zokutywina zihamba ngokumalunga nomnye.Le nto inokwenzeka kakhulu ukuba umphezulu wokutywina unoburhabaxa obuphezulu.Umphezulu wokutywina uya kuguga okanye ujike kancinane ngenxa yokugruzuka kwediskhi yevalvu kunye nokucinezelwa komphezulu wokutywina xa ibuyela kwisitulo sevalve ngexesha lomsebenzi wokuvala.

6. Ukunxitywa kunye nokukrazula

Umphezulu wokutywina uya kuphelelwa ngamandla ngokuhamba kwexesha ukusuka kwisenzo sokutshintshana kwemithwalo, okukhokelela ekuphuhliseni iintanda kunye neeleyile zokuxebula.Emva kokusetyenziswa ixesha elide, irabha kunye neeplastiki zivame ukuguga, nto leyo ephazamisa ukusebenza.

Kucacile kuphononongo lwezizathu zokutywinwa komonakalo owenziwe ngasentla ukuba ukukhetha izinto ezifanelekileyo zokutywinwa komhlaba, izakhiwo zokutywina ezifanelekileyo, kunye nobuchule bokucubungula kubalulekile ukunyusa umgangatho kunye nobomi benkonzo yendawo yokutywina kwiivalvu.
