1. Kusankha Malo Oyenera: PPL vs. Okhala ndi Zitsulo

Kusankha pakati pa PPL (Polyparaphenylene) ndi Metal-Seated trims kumadalira makamaka kutentha kogwirira ntchito, kuchuluka kwa tinthu tating'onoting'ono ta media, ndi kalasi yofunikira yotsekera.

2. Zinthu Zauinjiniya Za Malo Otentha Kwambiri

•Kapangidwe Kowonjezera ka BonnetChotsani chipinda chopakira tsinde kutali ndi malo otentha kwambiri. Zipsepse zoziziritsira zomwe zimamangidwa mkati mwake zimateteza zipangizo zopakira tsinde (graphite/V-ring yosinthasintha) ndi ma actuator opangidwa ndi manja/okha ku kutentha kwa mapaipi, zomwe zimapangitsa kuti ntchitoyo ikhale yayitali.
•Mapaketi Onyamula Zinthu ku Belleville Okhala Ndi MoyoKufutukuka ndi kupindika kwa kutentha kungayambitse kupumula kwa kulongedza. Ma diski athu a Belleville disc spring stacks amasunga kupanikizika kosalekeza kwa radial gland pa seti yolongedza, kuchotsa kutuluka kwa kutentha ndikutsatira miyezo ya API 641 / ISO 15848-1 yotsika mpweya.
•Mpumulo Wokulitsa Kutentha & KudziyeretsaMipando yachitsulo imakhala ndi zinthu zolimbitsa mphamvu za masika zomwe zimayamwa kutentha komwe kumachitika chifukwa cha madzi popanda kumangirira mpira. Kapangidwe kake ka scraper kamene kali ndi m'mphepete mwake kamapukuta tinthu tating'onoting'ono tomwe timasungunuka pamwamba pa mpira panthawi yozungulira kotala.
•Zophimba Zolimba za HVOF ZapamwambaUkadaulo wa High-Speed ​​​​Oxygen-Fuel (HVOF) umagwiritsa ntchito Tungsten Carbide kapena Chrome Carbide pa mpira ndi mphete za mipando zomwe zimakhala ndi mphamvu zomangira zopitilira 10,000 PSI, zomwe zimapangitsa kuti zikhale zolimba mpaka HRC 70 kuti zisawonongeke kwambiri.

5. Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri pa Uinjiniya)

Q1: Kodi kutentha kwakukulu kogwirira ntchito kwa ma valve a mpira okhala ndi PPL ndi kotani poyerekeza ndi ma valve a mpira okhala ndi zitsulo?

Mipando ya PPL (Polyparaphenylene) imagwira ntchito bwino mpaka 280°C–300°C (536°F–572°F) ya zakumwa zoyera ndi nthunzi. Ma valve a mpira okhala ndi zitsulo okhala ndi HVOF hardfacing (Tungsten Carbide, Chrome Carbide, kapena Stellite) amapangidwa kuti azitha kugwira ntchito molimbika mpaka 550°C–650°C (1022°F–1202°F) komanso malo olumikizirana.

Q2: N’chifukwa chiyani bonnet yotalikirapo imafunika pa ma valve a mpira otentha kwambiri?

Boneti yotambalala imasuntha bokosi lonyamulira tsinde kutali ndi thupi la payipi yotentha, ndikuchotsa kutentha kowala. Izi zimasunga zomatira za tsinde (monga graphite yosinthasintha) mkati mwa kutentha komwe zimagwira ntchito bwino, zimaletsa kuwonongeka kwa kutentha, ndipo zimateteza ma actuator amagetsi kapena opumira kuti asatenthe kwambiri.

Q3: Kodi mumaletsa bwanji kutsekeka/kugwa kwa mpira pa kutentha kwakukulu?

Kukula kwa kutentha kumayendetsedwa kudzera mu kusankha zinthu zosiyanasiyana molondola (kufananiza ma coefficients okulitsa kutentha kwa thupi, mpira, ndi tsinde) ndikuyika zopatsa mphamvu za masika zomwe zimakhala ndi moyo kumbuyo kwa mphete za mipando. Masisikawa amakanikiza kuti atenge kukula kwakukulu kwa kutentha popanda kuwonjezera mphamvu yogwirira ntchito kapena kuyambitsa kulumikizana kwa makina.
