TUV umboni NSEN butterfly vavu NSS mayeso

Vavu ya NSEN posachedwapa idayesa kusalowererapo kwa mchere wa valve, ndipo idapambana mayesowo pansi pa umboni wa TUV.Utoto womwe umagwiritsidwa ntchito pa valavu yoyesedwa ndi JOTAMASTIC 90, mayesowo amatengera muyezo wa ISO 9227-2017, ndipo nthawi yoyeserera imatha maola 96.

NSEN BUTERFLY VALVE ISO9227-2017

Pansipa ndifotokoza mwachidule cholinga cha mayeso a NSS,

Mayeso opopera mchere amatengera chilengedwe cha nyanja yamchere kapena nyengo yamalo amchere amchere, ndipo amagwiritsidwa ntchito poyesa kukana kwa kutsekemera kwa mchere wa zinthu, zida ndi zigawo zawo zoteteza.

Muyezo woyezetsa kutsitsi umafotokoza momveka bwino momwe amayesera, monga kutentha, chinyezi, kusungunuka kwa sodium chloride solution ndi pH mtengo, ndi zina zambiri, komanso kumayika patsogolo zofunikira zaukadaulo pakugwirira ntchito kwa chipinda choyezera mchere.Njira zowonera zotsatira za mayeso opopera mchere ndi monga: njira yoweruzira, kuyeza kwake, njira yoweruza yowononga mawonekedwe, ndi njira yowunikira ziwerengero za corrosion data.Zogulitsa zomwe zimafunikira kuyesedwa kwa kupopera mchere ndizinthu zina zachitsulo, ndipo kukana kwa dzimbiri kumafufuzidwa poyesa.

Kuyesa kwachilengedwe koyerekeza ndi kugwiritsa ntchito mtundu wa zida zoyesera ndi bokosi loyezera mlengalenga-mchere wopopera, m'malo mwake, njira zopangira zimagwiritsidwa ntchito popanga malo opopera mchere kuti awone kuchuluka kwa dzimbiri la kupopera mchere. kukana kwa mankhwala .Poyerekeza ndi chilengedwe, mchere wambiri wa chloride m'malo opopera mchere ukhoza kukhala kangapo kapena kachulukidwe kambiri kakupopera mchere kachilengedwe, komwe kumawonjezera kuchuluka kwa dzimbiri.Kuyesedwa kwa mchere wa mchere wa mankhwalawa kumachitika ndipo zotsatira zake zimapezeka Nthawiyo imafupikitsidwanso kwambiri.Mwachitsanzo, ngati chitsanzo cha mankhwala chikayesedwa m'malo achilengedwe, zingatenge chaka chimodzi kudikirira kuti dzimbiri, pomwe kuyezetsa kofananira ndi momwe chilengedwe chimapangidwira mchere chimangofunika maola 24 okha kuti mupeze zotsatira zofanana.

Mayeso osalowerera ndale (mayeso a NSS) ndiye njira yoyamba komanso yogwiritsidwa ntchito kwambiri poyesa dzimbiri.Imagwiritsa ntchito 5% sodium chloride salt aqueous solution, pH value ya yankho imasinthidwa m'malo osalowerera (6-7) ngati njira yopopera.Kutentha kwa mayeso ndi 35℃, ndipo kuchuluka kwa sedimentation kwa kupopera mchere kumafunika kukhala pakati pa 1~2ml/80cm²·h.
