Indlela yekukhetsa kahle tintfo tekuvala .

Ngutiphi letinye tintfo letibalulekile lokufanele uticabangele nawukhetsa tintfo letifanele tekuvala tesicelo?

Intsengo lenhle kanye nemibala lefanelekile

Kutfolakala kwetimphawu

Tonkhe tintfo letinemtselela eluhlelweni lwekuvala: sib. libanga lekushisa, lutfuli kanye nemfutfo

Leti tonkhe tintfo letibalulekile lokufanele uticabangele eluhlelweni lwakho lwekuvala. Nangabe tonkhe letintfo tatiwa, kutawuba melula kukhetsa tintfo letifanele.

Kepha imfuneko kutsi lemphahla kumele ihlale isikhathi lesidze. Ngako-ke intfo yekucala lokufanele uyicabangele kusebenta kwebuchwepheshe. Ake sicale ngesici sekusebenta.

Sikhatsi sekuphila kweluhlelo kanye netindleko tintfo letibalulekile (I-Tianjin Tanggu I-Valve Yekuvala Emanti) kutsi sicabangele. Tonkhe tintfo titawutsintsa kusebenta kwesicelo sakho. Kubalulekile kucabanga ngetintfo tekuklama ngekuya kwesicelo. Loku kufaka tintfo letisetjentisiwe, bobunjwa be hardware kanye netinchubo tekukhicita. Kukhona netintfo temvelo letifanele kutsi ticatjangelwe kufaka: kucindzeteleka, kushisa, sikhatsi, kuhlangana kanye netindzaba.

i-elastomera

Elastomers bathandwa ngoba kugucugucuka kwawo lokuhle. Kute letinye tintfo letinelizinga lelifanako lekugucugucuka.

Letinye tintfo letifana nema polyurethanes kanye nemapulasitiki lashisako timelana kakhulu nekucindzeteleka kunema elastomers.

Tintfo tenjoloba tingasetjentiswa ngetindlela letehlukahlukene tekusebenta letehlukene.

Timphahla letibalulekile temshini tifaka ekhatsi .

Letinye tintfo letibalulekile tifaka ekhatsi .

•Isethi yekucindzetela

•kumelana nekushisa

•kugucugucuka lokuphansi kwekushisa

•kuhambisana kwemakhemikhali

•Kulwa nekuguga

•kumelana nekuguga

Sici lesibaluleke kakhulu elasticity impahla iraba. Ase sifundze kabanti ngaloku.

Kugucugucuka kungumphumela wekutsi kube ne-vulcan. Tintfo te-elastomeric, letifana nerabha le-vulcanized, titawubuyela esimeni sato sekucala uma tikhubatekile.

Tintfo letingagucuki, njengerabha lengakagucuki, angeke tibuyele esimeni sato sekucala uma tikhubatekile. Kukhicitwa kwemlilo (njengeIvalvu levivane lephindvwe kabili) yinchubo yekugucula iraba ibe yintfo ye-elastomeric.

Kukhetfwa kwe-elastomers kusekelwe kakhulu ku:

•libanga lekushisa lokusebenta

•Kumelana netintfo letimanti kanye nemagesi

•Kumelana nesimo selitulu, i-ozone kanye nemisebe ye-UV

Kukhetfwa kwe-elastomers kusekelwe kakhulu ku:

Tintfo letisitfupha lokufanele ticatjangelwe nawukhetsa tintfo tekuvala emavalvu

Indzawo yekuvala yindzawo lebaluleke kakhulu yekusebenta ye .ivalvu, lizinga lendzawo yekuvala litsintsa ngalokucondzile imphilo yekusebenta ye .ivalvu, futsi tintfo tendzawo yekuvala tiyintfo lebalulekile kucinisekisa lizinga lendzawo yekuvala. Ngako-ke, letintfo letilandzelako kufanele ticatjangelwe uma ukhetsa ivalve kuvala ebusweni impahla:

1Kumelana nekugcola. “Kugcola” yinchubo lapho khona indzawo yekuvala ilimala ngaphansi kwesento sendzawo lesemkhatsini. Uma indzawo yekuvala igcobile, kusebenta kwekuvala angeke kucinisekiswe, ngako-ke tintfo tendzawo yekuvala kumele timelane nekugcola. Kumelana nekugcola kwentfo kuya kakhulu ngekwakheka kwentfo kanye nekusimama kwayo kwemakhemikhali.

2Kulwa nekuguga. “Kuklwebheka” kusho umonakalo lobangelwa kukhuhlana kwetintfo ngesikhatsi sekuhamba lokuhlobene kwendzawo yekuvala. Loluhlobo lwemonakalo nakanjani lutawubangela kulimala endzaweni yekuvala. Ngakoke, lentfo yekuvala lesetulu kumele ibe netimphawu letinhle tekulwa nekuklwebheka, ikakhulukati kumavalvu esango. Kumelana nekuklwebheka kwentfo kuvame kuncunywa timphahla tangekhatsi talentfo.

3Kumelana nekuguguleka kwemhlabatsi. “Kuguguleka” yinchubo yekubhubhisa indzawo yekuvala uma lendzawo lesemkhatsini igeleta kulendzawo yekuvala ngesivinini lesikhulu. Loluhlobo lwemonakalo lubonakala kakhulu kuma throttle valves kanye nema valve ekuphepha lasetjentiswa ekushiseni lokusetulu kanye nekucindzeteleka lokusetulu kwemphunga, futsi kunemitselela lemikhulu ekulimaleni kwekusebenta kwekuvala. Ngakoke, kumelana nekuguguleka nako kungulenye yetintfo letibalulekile tekuvala tintfo letingetulu.

4Kufanele ibe nebucini lobutsite, futsi bucini butawuwela kakhulu ngaphansi kwekushisa lokusebenta lokucacisiwe.

5Le linear expansion coefficient yendzawo yekuvala kanye nemphahla yemtimba kumele ifane, lokuyintfo lebaluleke kakhulu ekwakhiweni kwendandatho yekuvala, kwentela kugwema kucindzeteleka lokungetiwe kanye nekukhululeka ngesikhatsi sekushisa lokusetulu.

6Isetjentiswa ngaphansi kwetimo tekushisa letisetulu, kumele kube ne anti-oxidation leyenele, kumelana nekudzinwa ngekushisa kanye netindzaba temjikeleto wekushisa.

Ngaphansi kwetimo letikhona nyalo, kumatima kutfola intfo yekuvala lesetulu lehlangabetana ngalokuphelele naletidzingo letingenhla. Singagcila kuphela ekuhlangabetaneni netidzingo tetici letitsite ngekuya kwetinhlobo letehlukene tevalve kanye nekusetjentiswa. Sibonelo, emavalvu lasetjentiswa etindzabeni letinesivinini lesikhulu kumele anake kakhulu tidzingo tekumelana nekuguguleka kwemhlabatsi wekuvala; futsi uma lendzawo lesemkhatsini icuketse kungcola lokucinile, lendzawo yekuvala lesetulu lenebucini lobuphakeme kumele ikhetfwe.
