Ukhetho Olubalulekileyo Ekusebenzeni kweValve yeSolenoid: Isikhokelo Sokukhetha Izinto Zokuvala​

Intshayelelo​

Kwi-automation yemizi-mveliso, iivalvu ze-solenoid zisebenza njengezinto ezibalulekileyo zokulawula ukuhamba kolwelo kwizicelo eziqala ekuvelisweni nasekusetyenzisweni kweekhemikhali ukuya kumandla kunye nokhathalelo lwempilo. Ngelixa uyilo lweevalvu kunye nokusebenza kakuhle kwe-electromagnetic kuhlala kunikwa ingqwalasela ebalulekileyo, ukukhethwa kwezinto zokutywina kuhlala kuyinto ebalulekileyo ekusebenzeni kwexesha elide. Iitywina zithintela ukuvuza kwangaphakathi nangaphandle, zigcina ukuthembeka koxinzelelo, kwaye zimelana nokuwohloka okuvela kwimidiya, ubushushu, kunye nemijikelo yokusebenza. Ukungaqondi kakuhle ukuhambelana kwazo neemeko zokusebenza kunokukhokelela ekusileleni kwangethuba, kwiingozi zokhuseleko, kunye nexesha lokungasebenzi elingabizi kakhulu. Eli nqaku lihlola iipolymers ezintathu zokutywina ezisetyenziswa kakhulu—I-NBR, i-FKM, kunye ne-EPDM—kwaye ibonelela ngesakhelo esicwangcisiweyo sokufanisa iipropati zezinto kunye neemfuno zesicelo.

1. Indima yeZitywino kwiValve yeSolenoid ethembekileyo

Iitywina kwiivalvu ze-solenoid zenza imisebenzi emininzi ebalulekileyo:

Ukuthintela Ukuvuza: Ngokwenza imiqobo eqinileyo phakathi kwezinto ezihambayo kunye nemizimba yeevalvu, izitywino ziqinisekisa ukuba akukho kuvuza kuzo zombini iinkqubo ezizinzileyo nezitshintshayo.

Ukumelana neekhemikhali: Kufuneka zikwazi ukumelana nokuchatshazelwa zizinto ezirhabaxa, kuquka iioyile, iiasidi, izinyibilikisi, okanye umphunga, ngaphandle kokudumba, ukuqhekeka, okanye ukwehla komgangatho.

Uhlengahlengiso lobushushu: Izitywini zigcina ukuthamba kwazo zonke iimeko zobushushu ezigqithisileyo, ukusuka kwiimeko eziguquguqukayo ukuya kwiindawo ezinobushushu obuphezulu.

Ukuqina Kwemishini: Zinyamezela ukucinezelwa okuphindaphindiweyo kunye nokungqubana okuvela ekusebenzeni kwevalvu, zimelana nokuguguleka kunye nokuphuma kwimijikelo yezigidi ngezigidi.

Ukukhetha izinto ezingalunganga kunokukhokelela ekuqineni kwesitywino, ekukhupheni, okanye ekuboleni kweekhemikhali—izizathu eziqhelekileyo zokungasebenzi kakuhle kweevalvu.
