1. Kusarudza Nzvimbo Yakakodzera: PPL vs. Yakagarwa nesimbi

Kusarudza pakati pePPL (Polyparaphenylene) neMetal-Seated trims kunonyanya kuenderana nekupisa kwekushanda, mazinga ezvimedu zvepakati, uye kirasi yekuvharira inodiwa.

2. Zvinhu zveUinjiniya zveNzvimbo Dzinopisa Zvakanyanya

•Dhizaini Yekupenya Kwebhoniti YakawedzerwaBvisa kamuri rekurongedza tsinde kure nenzvimbo dzemuviri dzinopisa zvakanyanya. Zvidimbu zvekutonhodza zvinodziya zvakavakirwa mukati zvinodzivirira zvinhu zvekurongedza tsinde (graphite/V-ring inochinjika) uye manual/automated actuators kubva pakupisa kwepaipi inopenya, zvichiita kuti igare kwenguva refu.
•Maseti ekutakura eBelleville Akazara MhenyuKukura uye kudzikira kwekupisa kunogona kukonzera kuzorora kwepakeji. Mapuringi edu eBelleville disc spring anoramba achimanikidza radial gland paseti yekurongedza, achibvisa kudonha kwekupisa uye achitevedzera mitemo yeAPI 641 / ISO 15848-1.
•Kurerutsira Kuwedzera Kwekupisa & KuzvichenesaZvigaro zvesimbi zvine zvinopa simba rematsime zvinotora mvura yakawanda zvichikwidza kupisa pasina kusunga bhora. Dhizaini yekubvisa bhora iri muchimiro cheacute-edged scraper inoita kuti pave nezvikamu zvakaungana pamusoro pebhora panguva yekutenderera kwekota.
•HVOF Yepamusoro-soro Hardfacing CoatingsTekinoroji yeHigh-Velocity Oxygen-Fuel (HVOF) inoshandisa Tungsten Carbide kana Chrome Carbide kubhora nepazvigaro zvine simba rekubatanidza rinodarika 10,000 PSI, zvichiita kuti hunyoro husvike HRC 70 kuti husanyanya kukwesha.

5. Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa NezveUinjiniya)

Mubvunzo 1: Ndeipi tembiricha yepamusoro yekushandisa mavharuvhu ebhora ePPL seated vs. mavharuvhu ebhora esimbi seated?

Zvigaro zvePPL (Polyparaphenylene) zvinoshanda zvakanaka kusvika 280°C–300°C (536°F–572°F) kuti zvive zvemvura yakachena uye utsi. Mavharuvhu ebhora ane simbi ane HVOF hardfacing (Tungsten Carbide, Chrome Carbide, kana Stellite) akagadzirwa kuti ashande zvakanyanya kusvika 550°C–650°C (1022°F–1202°F) uye abrasive media.

Mubvunzo wechipiri: Sei bhoneti yakareba ichidiwa pamavharuvhu ebhora anodziya zvakanyanya?

Bhoneti refu rinobvisa bhokisi rekuisa stem kubva mumuviri wepombi inopisa, richibvisa kupisa kunopenya. Izvi zvinochengetedza stem seals (senge flexible graphite) mukati menguva yakachengeteka yekushanda, zvinodzivirira kupera kwekupisa, uye zvinodzivirira ma actuator emagetsi kana epneumatic kuti asanyanya kupisa.

Mubvunzo wechitatu: Unodzivirira sei kuvharika kwebhora/kutsemuka kwemhepo pakupisa kwakanyanya?

Kuwedzera kwekupisa kunotarisirwa kuburikidza nekusarudza zvinhu zvakasiyana-siyana (kuenzanisa ma coefficients ekuwedzera kwekupisa kwemuviri, bhora, uye tsinde) uye kuisa ma spring energizers ari mhenyu ari kumashure kwezvigaro. Ma springs aya anodzvinyirirwa kuti atore kuwedzera kwakanyanya kwekupisa pasina kuwedzera torque yekushanda kana kukonzera kubatana kwemechanical.
