5. Cov Lus Nug Feem Ntau (Cov Lus Nug Txog Kev Tsim Kho)

Q1: Qhov kub siab tshaj plaws rau PPL zaum lub pob valve piv rau cov hlau zaum lub pob valve yog dab tsi?

Cov rooj zaum PPL (Polyparaphenylene) ua haujlwm tau zoo txog li 280 ° C–300 ° C (536 ° F–572 ° F) rau cov kua huv thiab cov pa dej. Cov pob valve uas muaj hlau nrog HVOF hardfacing (Tungsten Carbide, Chrome Carbide, lossis Stellite) tau tsim los rau kev pabcuam hnyav txog li 550 ° C–650 ° C (1022 ° F–1202 ° F) thiab cov khoom siv abrasive.

Q2: Vim li cas thiaj yuav tsum muaj lub hau ntev rau cov pob qhov kub siab?

Lub hau npog ntev ua rau lub thawv ntim khoom txav mus deb ntawm lub cev kav dej kub, ua rau lub cua sov ploj mus. Qhov no ua rau cov foob pob (xws li graphite yooj ywm) nyob hauv lawv qhov kub thiab txias, tiv thaiv kev puas tsuaj los ntawm cua sov, thiab tiv thaiv cov actuators hluav taws xob lossis pneumatic los ntawm kev kub dhau.

Q3: Koj ua li cas thiaj tiv thaiv tau lub pob kom tsis txhob xauv/qaug zog thaum kub siab?

Kev nthuav dav ntawm qhov kub thiab txias yog tswj los ntawm kev xaiv cov khoom siv sib txawv (sib phim cov coefficients ntawm kev nthuav dav ntawm lub cev, lub pob, thiab lub qia) thiab kev siv cov khoom siv zog ntawm lub caij nplooj ntoos hlav tom qab lub nplhaib ntawm lub rooj zaum. Cov caij nplooj ntoos hlav no nias kom nqus tau qhov kev nthuav dav ntawm qhov kub thiab txias yam tsis ua rau lub zog ua haujlwm nce ntxiv lossis ua rau muaj kev sib txuas ntawm cov khoom siv.
