Kusindikiza mphete ndi ntchito zomwe zimagwiritsidwa ntchito kwambiri mu masilinda a hydraulic

Makina omanga sangasiyanitsidwe ndi masilinda amafuta, ndipo masilinda amafuta sasiyanitsidwa ndi zidindo. Chisindikizo wamba ndi mphete yosindikizira, yomwe imatchedwanso kuti mafuta osindikizira, omwe amagwira ntchito yolekanitsa mafuta ndi kuteteza mafuta kuti asasefukire kapena kudutsa. Apa, mkonzi wamakina amakusankhani mitundu ina yodziwika bwino ndi mitundu ya zisindikizo za silinda.

Zisindikizo zodziwika bwino zama hydraulic cylinders ndi zamitundu iyi: zisindikizo zafumbi, zosindikizira za pisitoni, zisindikizo za buffer, mphete zothandizira, zosindikizira zomaliza ndi zosindikizira za piston.

Mphete yafumbi
Mphete yopanda fumbi imayikidwa kunja kwa chivundikiro chomaliza cha silinda ya hydraulic kuti ateteze zowononga zakunja kulowa mu silinda. Malinga ndi njira yokhazikitsira, imatha kugawidwa mumtundu wa snap-in ndi mtundu wa press-in.

Mitundu yoyambira ya snap-in fumbi zosindikizira
Chosindikizira cha fumbi cha snap-in ndicho chofala kwambiri. Monga momwe dzinalo likusonyezera, chisindikizo chafumbi chimamatira pakhoma pakhoma lamkati la kapu yomaliza ndipo chimagwiritsidwa ntchito m'malo ovuta kwambiri. Zomwe zimapangidwa ndi chisindikizo cha fumbi nthawi zambiri zimakhala polyurethane, ndipo mawonekedwe ake amakhala ndi zosiyana zambiri, monga H ndi K zigawo zodutsana ndi milomo iwiri, koma zimakhala zofanana.

Zosintha zina za ma wiper ophatikizika
Chopukuta chamtundu wa makina osindikizira chimagwiritsidwa ntchito pansi pa zovuta komanso zolemetsa, ndipo sichimangirira mu poyambira, koma chitsulo chosanjikiza chimakutidwa ndi zinthu za polyurethane kuti chiwonjezere mphamvu, ndipo chimakanikizidwa kumapeto kwa chivundikiro cha hydraulic. yamphamvu. Zisindikizo za fumbi zosindikizira zimabweranso m'njira zosiyanasiyana, kuphatikizapo milomo imodzi ndi milomo iwiri.

Chisindikizo cha piston
Chisindikizo cha piston rod, chomwe chimadziwikanso kuti U-cup, ndiye chosindikizira chachikulu cha pisitoni ndipo chimayikidwa mkati mwa chivundikiro cha hydraulic cylinder kuteteza mafuta a hydraulic kuti asatuluke. Mphete yosindikiza ya piston imapangidwa ndi mphira wa polyurethane kapena nitrile. Nthawi zina, iyenera kugwiritsidwa ntchito limodzi ndi mphete yothandizira (yomwe imatchedwanso mphete yosungira). Mphete yothandizira imagwiritsidwa ntchito pofuna kuteteza mphete yosindikiza kuti isafinyidwe ndi kupunduka popanikizika. Zisindikizo za ndodo zimapezekanso m'mitundu ingapo.

Chisindikizo cha buffer
Zisindikizo za ma cushion zimakhala ngati zisindikizo zachiwiri kuti ziteteze ndodo ya pistoni kuti isawonjezeke mwadzidzidzi pakukakamiza kwamakina. Pali mitundu itatu ya zisindikizo za buffer zomwe ndizofala. Mtundu A ndi chisindikizo chimodzi chopangidwa ndi polyurethane. Mitundu B ndi C ndi zigawo ziwiri kuteteza chisindikizo extrusion ndi kulola chisindikizo kupirira mavuto apamwamba.

chiwongolero chothandizira mphete
Mphete yothandizira kalozera imayikidwa pachivundikiro chomaliza ndi pisitoni ya silinda ya hydraulic kuti ithandizire ndodo ya pisitoni ndi pisitoni, kutsogolera pisitoni kuti iyende molunjika, ndikuletsa kukhudzana kwachitsulo ndi chitsulo. Zida zimaphatikizapo pulasitiki, mkuwa wokutidwa ndi Teflon, etc.

Chisindikizo chomaliza
Mphete yosindikizira yomaliza imagwiritsidwa ntchito kusindikiza chivundikiro cha silinda ndi khoma la silinda. Ndichisindikizo chokhazikika ndipo chimagwiritsidwa ntchito kuteteza mafuta a hydraulic kuti asatuluke kuchokera pampata pakati pa chivundikiro chomaliza ndi khoma la silinda. Kawirikawiri imakhala ndi mphira wa nitrile O-ring ndi mphete yobwerera (kusunga mphete).

Piston chizindikiro
Chisindikizo cha pistoni chimagwiritsidwa ntchito kupatula zipinda ziwiri za silinda ya hydraulic ndipo ndiye chisindikizo chachikulu mu silinda ya hydraulic. Kawirikawiri zidutswa ziwiri, mphete yakunja imapangidwa ndi PTFE kapena nayiloni ndipo mphete yamkati imapangidwa ndi mphira wa nitrile. Tsatirani Mechanical Engineers kuti mudziwe zambiri zamakina. Zosiyanasiyana zimapezekanso, kuphatikiza mkuwa wokutidwa ndi Teflon, pakati pa ena. Pa masilinda ochita kamodzi, palinso makapu opangidwa ndi polyurethane U.
