Izizathu ezithandathu zomonakalo kumphezulu wokutywina kwevalve

Ngenxa yomsebenzi wokwenza into yokuphawula kunye nokudibanisa, ukulawula nokusasaza, ukwahlula kunye nokudibanisa imithombo yeendaba kwivali, ihlelo, kwaye inxibe kakhulu kumonakalo.

There are two reasons for the damage to the sealing surface: human damage and natural damage. Human damage is caused by factors such as poor design, manufacturing, material selection, improper installation, poor use, and maintenance. Umonakalo wendalo kukudinwa kunye nokukrazula iimeko eziqhelekileyo zomsebenzi we-veli kwaye kubangelwa kukungafikeleli kunye nokukhukuliseka komhlaba wokutywina yimithombo yeendaba.

Umgangatho womatshini ohlutyuliweyo womgangatho wokutywina: Oku kubonakala ikakhulu kwiziphene ezinjengeendawo ezinqabileyo, iipores, kunye nekhubalo kumhlaba wokutywina. This is caused by improper selection of welding and heat treatment standards, as well as poor operation during welding and heat treatment. The sealing surface's hardness is too high or too low due to improper material selection or improper heat treatment. Umgangatho wokutywina komhlaba ongalinganiyo kunye nokunganyangeki okungalunganga kokuxhaphaza ikakhulu kubangelwa kukuvuthelwa kwentsimbi engaphantsi komhlaba ngexesha lenkqubo ye-welding, evaliweyo. Of course, design issues also exist in this regard.

ivalves ngokweemeko zokusebenza, usebenzisa ivalve evaliweyo njenge-valve evuthayo, kubangela uxinzelelo olugqithisileyo ngexesha lokuvalwa, ukuvalwa ngokukhawuleza, okanye ukuvalwa okungaphelelanga, kubangela ukhula. Ukufakwa okungalunganga kunye nolondolozo olubi kukhokelela ekusebenzeni okungaqhelekanga kumhlaba wokutywina, obangelaivalveukusebenza ngokugula kunye nokwenzakalisa umphezulu wetywina.

I-Chemical Shorsion yePhepha lePhepha lePhepha: Iphakathi ejikeleze umzantsi wokutywina kunye nomphezulu wokutywina ngaphandle kokuvelisa indawo yangoku, ekhulisa umphezulu wokutywina. Electrochemical corrosion, contact between the sealing surfaces, contact between the sealing surface and the closing body andivalveUmzimba, kunye nolwahluko kumxholo woxinzelelo kunye neoksijini ye-OXPIURE, zonke zivelisa umahluko onokubakho, kubangela ukususwa kwe-elektroniki kunye nokucoca umhlaba otyhidiweyo.

Ukhukuliseko lwe-Presium: Esi sisiphumo sokunxiba, ukukhukuliseka, kunye nocaphulo lomphezulu wokutywina xa ukuhamba okuphakathi. Kwindawo ethile ye-velocity, edada amasuntswana amahle kwindawo ephakathi enomgangatho wokutywina, obangela umonakalo wengingqi. Indawo ehamba ngesantya esiphezulu ihamba ngokuthe ngqo kumhlaba wokutywina, obangela umonakalo wengingqi. Xa i-Medium ixube kwaye ivalwe ngokuyinxenye, iiblubs ziyaqhushumba kwaye zinefuthe kumhlaba wokutywina, obangela umonakalo wengingqi. Ukudityaniswa kokhukuliseko kunye nokuthuka kweekhemikhali ze-Providences ephakathi kumhlaba wokutywina.

Umonakalo woomatshini: Umphezulu wokutywina uya kukrwitwa, ugxunyekwe, kwaye ucekeceke ngexesha lenkqubo yokuvula kunye nokuvala. I-Atom phakathi kwemicimbi emibini yokutywina ijongane nobushushu obuphezulu kunye noxinzelelo, ukuvelisa i-anomenon. Xa iindawo ezimbini zokutywina zihamba ngokuhambelana nomnye nomnye, indawo yokubulala i-adhesion iqhekekile. Ukuphakama komgangatho womhlaba wokutywina, kokukhona kusenokwenzeka ukuba le nto inokwenzeka. Xa ivalve ivaliwe, i-valve i-idic iya kuqhubela phambili kwaye ityumke umphezulu wokutywina, obangela ukunxiba okanye i-induction kumhlaba wokutywina.

Umonakalo wokudinwa: Umphezulu wokutywina uxakwe kutshintshile imithwalo ngexesha lokusetyenziswa kwexesha elide, obangela ukudinwa kunye nokukhokelela kubuqhetseba kunye nokufikelelwa. Irabha kunye neplastiki zithambekele ekubeni ziluphando emva kokusetyenziswa kwexesha elide, okukhokelela kwintsebenzo esemsebenzini. Ukusuka kuhlalutyo lwezizathu ezingentla zomonakalo wokutywina, unokubonwa ukuba ukwenzela ukuphucula umgangatho kunye nobomi benkonzo we-valve yokutywina, izixhobo zokutywina ezifanelekileyo, kunye neendlela zokulungisa ezinokukhethwa.
