Hydraulic system ni hta ahkyak ai matut mahkai lam langai hku nna, hydraulic matut mahkai ai lam ni a madung bungli gaw, pipe hte daw ni a lapran hydraulic fluid (galaw madang sau) hpe kam mai ai hte hkrak hkra htawt sit ya lu na matu rai nna, system a n-gun hpe makawp maga na matu hte hka lim ai lam hpe makawp maga na matu re. Shanhte a bungli galaw ai lam hta, hka htung ni hpe n-gun jaw ai lam, arung arai ni hpe shinggyin la ai hpaji masa, jak rung hkrang ni a synergistic effects ni lawm ai. Lahta na sawk sagawn ai lam gaw, n-gun ja ai masa ni a npu e, npawt nhpang nsam, sealing ladat ni, bungli galaw ai lam ni hpe madung tawn ai.
1. Structural matut mahkai lam hte npawt nhpang bungli galaw ai shara ni hpe gram lajang ai lam
Hydraulic connector a madung hkrang gaw, madung hku nna daw masum lawm ai: hkum hkrang madung (connecting section), sealing assembly, hte locking galaw ai ladat. Hkum hkrang madung gaw hka n-gun (peli pipe hte hose zawn re ai) shing nrai hydraulic n-gun (p pump, valve, cylinder zawn re ai) ni hte matut mahkai na lit nga ai. Shi a kata na bunghku hkrang gaw, hka htung a diameter hte hkrang hte bung ra ai. Sealing component gaw core functional unit rai nna, common hkrang ni gaw O{3}}rings (rubber (sh) polyurethane), composite gaskets (metal hte rubber composites), shing nrai, n-gun ja ai sealing surfaces (conical/spherical surfaces zawn re ai) ni lawm ai. Dai locking mechanism gaw, threaded connection (NPT hte BSPP madang ni zawn re ai), compression fittings ( SAE J514 compression fittings zawn re ai), shing nrai, lawan ai- gaw, gap hkat jahkring ai jak ni hta law law lang lang lang ai, tsaw ai{7}}pressure n-gun kaba ai ni zawn re ai) hpe n-gun jaw ya nna, pat shingdang ya ai.
Magam bungli galaw ai hku yu yang, hydraulic connector ni gaw madung ra kadawn ai lam masum hpe kalang ta hkan sa ra ai: langai, n-hkap la ai sau lwi ai hpe hkam la lu na matu matut manoi hka lam hpe gawgap ra ai; lahkawng, system bungli galaw ai n-gun hpe hkam sharang lu ai (10-50 MPa, raitim grai sawng ai masa hta 100 MPa jan ai) hpe hkam sharang lu ai; masum ngu na hta, sealing component hku nna kata hte shinggan hka lim ai lam ni hpe pat shingdang ai hku nna, ngang grin ai system pressure hpe n-gun jaw na.
2. Sealing Mechanism: Pressure hku nna n-gun jaw ai lam
Hydraulic fittings ni a sealing galaw ai lam gaw shanhte a bungli galaw ai lam a madung rai nga ai. Shi a npawt tara gaw, "n-gun n-gun a hkum hkrang-tightening" ngu ai lahkawng lang na ladat ni hpe madung tawn ai. Hydraulic system hpe shamu shamawt ai shaloi, hka gaw pump a action npu hta shawng nnan na n-gun hpe shapraw ya ai. Ndai aten hta, n-gun rawt jat wa ai hte maren, sealing component ntsa na compressive n-gun grau law wa ai. Ga shadawn, O{6}}ring hpe radially hku nna shinggrup da ai, shi a matut mahkai ai shara hte matut mahkai ai lam hpe kalang ta jat wa ai, madung hkum hkrang hte matut mahkai ai lam lapran na microscopic gap ni hpe jahpring ya ai (ntsa kaw na n-gun n rawng ai majaw byin pru wa ai hka htung ni zawn re ai). Conical seals ni a matu (74℃taper angle zawn re ai ni a matu), n-gun kaba ai n-gun n-gun hpe n-gun rawng ai shara de nhtang wa shangun nna, sealing ntsa hpe grau ni htep hkra shadut ya ai, kaja ai ningmu hpe shabyin ya ai: "n-gun grau law ai, seal hpe grau n-gun ja hkra galaw ya ai."
Sealing gaw arung arai elasticity hpe sha n kam ai hpe sadi ra ai. Pre{1}}compression design gaw ahkyak ai. Ga shadawn, O{3}}rings ni gaw, n-gun n law ai npu hta pyi, shawng nnan na sealing hpe galaw lu na matu, n-gun n law ai aten hta pyi, 15%{7}30% shingjawng ai lam (dai manu gaw, rubber n-gun hte bungli galaw ai nbung katsi ai lam hta madung nga ai) ra ai. Hpa majaw nga yang, n-gun ja ai n-gun rawng ai lam ni a npu hta, n-gun rawng ai arung arai ni gaw, n-gun n-gun (ga shadawn, fiber{9}} n-gun rawng ai polyurethane O{11}rings) hte media n-gun shayawm ai lam hpe ninghkap lu ai (ga shadawn, fluoroelolome hpe phosphate ester hydaulic ntsin ni a matu htuk manu ai). N law htum pre-{12}}compression gaw, n-gun n law ai shara ni hta micro{13}}leakage byin shangun nna, pre-compression grai law ai majaw, sealing surface ntsa hta grai law hkra n-gun yawm mat chye ai (sh) hpawng chyawm ai hte garan ginhka ai lam ni hpe yak hkak shangun chye ai.
3. Hkum hkrang bungli galaw ai masa ni a npu e bungli galaw ai lam
Kaja wa nga yang, hydraulic connector ni gaw, chyahkring hkring n-gun galai shai ai lam ni hpe hkam sharang ra ai (ga shadawn, hydraulic shock a majaw byin pru wa ai, n-gun n-gun n-gun galai shai ai lam ni), katsi ai lam galai shai ai lam ( {2}℃du hkra -40℃du hkra nbung laru kaba ai hku galaw ai), hte jak rung ni a n-gun (ga shadawn, gawgap ai jak ni a n-gun n-htum ai zawn re ai). Ndai mayak mahkak ni hpe hparan na matu, shi a bungli galaw ai npawt tara gaw lawu na ladat ni hku nna ngang grin ai lam hpe lu la ai:
Shawng nnan, n-gun n-gun-absorbing hkrang: High{1}}end matut mahkai ai lam ni hta, n-gun n rawng ai hkrang ni hpe law law lang bang da ai (throttle grooves (sh) buffer chambers zawn re ai). Hydraulic shock byin wa ai shaloi, hka lim ai hkrang gaw n-gun jat wa ai aten hpe galu shangun nna, aten kadun laman hta n-gun grai law ai majaw seal hkrat sum ai hpe pat shingdang ya ai. Ga shadawn, tsaw ai{4}}}}} pressure hose connector nkau mi hta, shock n-gun hpe shayawm na matu, sau lwi ai lam hpe jat ya ai kata na spiral flow channel ni nga ai.
Lahkawng, thermal jat wa ai hka wa ai lam: Temperature galai shai ai lam gaw, n-gun jat ai lam hte n-gun shayawm ai lam ni hta shai hkat ai lam ni hpe byin shangun chye ai (ga shadawn, rubber gaw nbung katsi ai shara hta 10 lang jan na n-gun hte jat wa lu ai), dai gaw shawng na dazik hpe n-gun n rawng hkra galaw lu ai. Ndai lam hpe hparan na matu, matut mahkai lam nkau mi gaw "floating seal ring" hkrang hpe jai lang ma ai (dai zawn re ai ni gaw, n-gun rawng ai lahkawng lang O{2}ring lajang ai lam zawn re ai) hpe jai lang ma ai, dai gaw, n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun hpe gram lajang ya ai, n-gun n-gun n-gun n-gun n-gun n-gun hpe gram lajang ya ai.
Hpang jahtum, vibration hpe pat shingdang ai lam: Locking mechanism a anti- hpaw ai hkrang gaw ahkyak dik rai nga ai. Ga shadawn, threaded joints ni hpe spring washers (sh) nylon locknuts ni hte kayau nna, n-gun n rawng ai majaw n-gun n rawng hkra, n-gun n rawng ai hpe pat shingdang ai lam ni hpe lang ai. Maga mi de, n-gun rawng ai lam ni gaw, aten galu n-gun rawng ai npu hta pyi, matut mahkai lam a kam hpa mai ai lam hpe makawp maga na matu, pipe bunghku kata de hka lim ai jak hte matut mahkai ai lam hpe kam hpa nga ai.
Daw dan lam
Hydraulic fittings ni a bungli galaw ai tara gaw, madung hku nna "fluid lam hpe gawgap ai lam", "n-gun n-gun hpe shingdaw ai lam" hte "bungli galaw ai masa ni hpe n-gun n-gun hte galai shai ai lam" ni hpe kahkyin gumdin ai lam rai nga ai.
