Bulldozer sau dazik ni a madung amyu ni hte arawn alai ni hpe .
Sau hte seng ai amyu bawsang ni hte arawn alai ni hpe .
Hka hpe hka ja ai sau seal
Metal mechanical seals ni a majaw, lahkawng lang cone sau seals (sh) prat tup na seals ngu nna mung shamying ai, n-gun ja ai hkrang hte n-gun ja ai n-gun hpe ninghkap lu ai atsam nga ai. Dai gaw, n-gun ja ai, hkra machyi ai, n-gun kaba ai zawn re ai grai sawng ai bungli masa ni hpe hkan sa mai ai, dai hpe lam ni, gearbox ni, engineering hte lung seng htu ai jak ni a kaga shara ni hta grai lang mai ai. Shi a sealing npawt tara gaw O{2}ring (sh) n tara ai ring karum shingtau lam ni hpe kam hpa nga ai, hka lim ai lam hpe makawp maga ai lam hte n san seng ai lam ni hpe pat shingdang ai lam lahkawng lang galaw ai.
Skeleton sau dazik
Lahkawng hku garan nna, kata na n-gup hte shinggan na n-gup magap:
Internal skeleton sau seal: Rubber shinggan jut hpe magri n-gang hte shinggrup da ai, dai gaw n-gun ja ai bungli galaw ai lam hte htuk manu ai lam ni hpe hkam la lu ai, n-gun ja ai n-gun n-gun hpe pat da lu na matu htuk manu ai, n-gun n-gun hpe shayawm lu ai shafts ni hpe atsawm sha shayawm lu ai, n-gun n-gun hpe shayawm lu ai hte shaft hpe 35% shayawm lu ai.
Shinggan na n-gup n-gu sau seal: N-gup n-gu n-gun rawng ai n-gup n-gu hpe hpraw hkra galaw nna, n-gup n-gu n-gun n-rawng ai shara ni hta grai sawng ai makau grup yin ni a matu htuk manu ai.
O{0}}ring seal: N-gun ja ai mungkan ting hpe n-gun ja ai hku nna, arung arai hte n-gun ja ai lam ni hte maren (50Duro, 80Duro zawn re ai) hte maren, masat masa amyu myu hku garan mai ai, shing nrai, n-gun n-gun n-gun n-gun n-gun n-rawng ai n-gun n-gun n-gun n-gun n-rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai lam ni hpe n-gun n-rawng ai dynamic sealing scenario ni hta lang mai ai.
Madung galaw ra ai lam ni
Bulldozer ni law malawng gawgap ai shara ni, lung seng htu ai shara ni, kaga shara ni hta law law nga ai shara ni hta bungli galaw ai makau grup yin a majaw, sau seal ni gaw lawu na zawn galaw ra ai lam ni hpe hkan sa ra ai:
Sau hpe ninghkap lu ai atsam: Hka htung sau, gear sau hte kaga sau ni a n-gun hte n-gun yawm ai hpe ninghkap lu ai, n-gun rawng ai n-gun hpe n-gun jaw lu ai.
Hkringhtawng hpe ninghkap lu ai: jak rung bungli galaw ai aten hta nbung katsi ai lam hpe galai shai ai lam (galaw majaw -30℃kaw nna 120℃du hkra), nbung katsi ai shara hta n-gun n rawng ai, nbung n-gun n law ai shara ni hta n-gun n rawng ai.
War hpe ninghkap ai lam: Shafts (sh) bai htang ai daw ni hte matut mahkai ai shaloi, n-gun n rawng ai lam hpe shayawm ya lu nna, daw jau ai lam hpe jat ya lu ai.
Elastic hkam sharang ai lam: Dai gaw aten galu- aten ngut ai hpang mung, n-gun ja ai lam hpe n-gun jaw lu ai, sealing n-gup hte dazik shakap da ai npu lapran ngang kang ai hpe madi shadaw ya lu ai.
4, Masha law law a mara hte hpa lam ni .
Bulldozer sau n-gun n-gun yawm ai lam gaw, madung hku nna sau lwi ai lam hku nna dan dawng wa ai, dai lam ni gaw:

N kaja ai hku jung ai: skewed sau seals, scwwid n-gup, shing nrai, n-gun n rawng ai hka lim ai zawn re ai ni hpe jung ai shaloi, sau bang ai sau hpe n bang ai majaw byin pru wa ai.
Asak kaba wa ai hte bu hpun ai: Aten galu- aten la ngut ai hpang, rubber arung arai ni gaw asak kaba wa nna, shing nrai, pat da ai n-gup hpe n san seng ai majaw bu hpun ai majaw, n-gun n rawng mat ai.
N kaja ai bungli masa ni: n-gun rawng ai, katsi ai, shing nrai, sau awu asin byin ai ( metal n-gun ni hte kayau ai zawn re ai) gaw sau seal hkra machyi ai lam hpe lawan ladan byin shangun ai.
5, Maintenance hpaji jaw ai
Sau dazik a seal daw ni hpe ayan jep yu nna, sau lwi ai (sh) hka lim ai hpe mu yang, lawan ladan galai kau u.
Sau n-gun hpe galai ai shaloi, n-gun hte arung arai ni bung hkra, shawng na jak rung (sh) htuk manu ai hkrang hpe lata u.
N bang shi yang, n san seng ai lam ni hpe pat da ai shara ntsa na n san seng ai lam ni hpe jasan jaseng nna, n-gun n rawng ai sha, sau seal a n-gup hta sau bang ai sau law law hpe bang u.
Hydraulic sau hte gear sau hpe ayan galai nna, sau n san seng ai hpe shayawm na matu filter hpe jasan jaseng u.
Bulldozer sau dazik ni gaw kaji kajaw daw ni rai tim, arung arai ni hpe n-gun n rawng ai hku galaw na matu ahkyak ai. Sau n-gun hpe kade daram lata la nna gram lajang ai gaw, jak rung ni hkrat sum ai lam hpe atsawm sha shayawm ya lu nna, bungli galaw ai lam hpe grau kaja hkra galaw ya lu ai.
