Makina osindikizira a hydraulicKutuluka kwa mafuta kumachitika chifukwa cha zifukwa zambiri. Zifukwa zodziwika bwino ndi izi:
1. Kukalamba kwa zisindikizo
Zisindikizo zomwe zili mu makina osindikizira a hydraulic zidzakalamba kapena kuwonongeka nthawi yogwiritsira ntchito ikawonjezeka, zomwe zimapangitsa kuti makina osindikizira a hydraulic atuluke. Zisindikizozo zitha kukhala ma O-rings, mafuta oikira, ndi ma piston seals.
2. Mapaipi amafuta osakhazikika
Pamene makina osindikizira a hydraulic akugwira ntchito, chifukwa cha kugwedezeka kapena kugwiritsidwa ntchito molakwika, mapaipi amafuta amakhala otayirira, zomwe zimapangitsa kuti mafuta atuluke.
3. Mafuta ambiri
Ngati mafuta ochulukirapo awonjezeredwa ku makina osindikizira a hydraulic, izi zimapangitsa kuti kuthamanga kwa madzi m'thupi kukwere, zomwe zimapangitsa kuti mafuta atuluke.
4. Kulephera kwa ziwalo zamkati mwa makina osindikizira a hydraulic
Ngati ziwalo zina mkati mwa makina osindikizira a hydraulic zalephera, monga ma valve kapena mapampu, izi zingayambitse kutayikira kwa mafuta m'dongosolo.
5. Mapaipi osagwira bwino ntchito
Nthawi zambiri, mapaipi a hydraulic amafunika kukonzedwa chifukwa cha kulephera. Komabe, ubwino wa mapaipi obwezeretsedwanso si wabwino, ndipo mphamvu yonyamula mphamvu ndi yochepa, zomwe zimapangitsa kuti ntchito yake ikhale yochepa kwambiri. Makina osindikizira a hydraulic amataya mafuta.
Pa mapaipi olimba amafuta, khalidwe loipa limawonekera makamaka mu: makulidwe a khoma la chitoliro kukhala osalingana, zomwe zimachepetsa mphamvu yonyamulira ya chitoliro chamafuta. Pa mapaipi, khalidwe loipa limawonekera makamaka mu khalidwe loipa la rabara, kupsinjika kosakwanira kwa waya wachitsulo, kuluka kosagwirizana, komanso mphamvu yosakwanira yonyamula katundu. Chifukwa chake, chifukwa cha mphamvu yamphamvu ya mafuta opanikizika, zimakhala zosavuta kuwononga mapaipi ndikupangitsa kuti mafuta atuluke.
6. Kukhazikitsa mapaipi sikukwaniritsa zofunikira
1) Paipiyo siipindika bwino
Mukalumikiza chitoliro cholimba, payipi iyenera kupindika malinga ndi utali wopindika womwe watchulidwa. Kupanda kutero, payipiyo ipanga ma stress osiyanasiyana amkati opindika, ndipo mafuta adzatuluka chifukwa cha kuthamanga kwa mafuta.
Kuphatikiza apo, ngati utali wopindika wa chitoliro cholimba ndi wochepa kwambiri, khoma lakunja la chitoliro lidzachepa pang'onopang'ono, ndipo makwinya adzawonekera pakhoma lamkati la chitoliro, zomwe zimayambitsa kupsinjika kwamkati mu gawo lopindika la chitoliro, ndikufooketsa mphamvu yake. Pakangochitika kugwedezeka kwamphamvu kapena kupsinjika kwakunja kwamphamvu, chitolirocho chidzapanga ming'alu yopingasa ndi mafuta otayikira. Kuphatikiza apo, poyika payipi, ngati utali wopindika sukwaniritsa zofunikira kapena payipi yapindika, zidzapangitsanso payipi kusweka ndikutulutsa mafuta.
2) Kukhazikitsa ndi kukonza mapaipi sikukwaniritsa zofunikira
Zinthu zofala kwambiri zosakhazikika ndi zomangira ndi izi:
① Akakhazikitsa chitoliro cha mafuta, akatswiri ambiri amaiyika ndi kuyikonza mokakamiza mosasamala kanthu kuti kutalika, ngodya, ndi ulusi wa chitolirocho ndi zoyenera. Chifukwa chake, chitolirocho chimasokonekera, mphamvu yoyika imapangidwa, ndipo zimakhala zosavuta kuwononga chitolirocho, zomwe zimachepetsa mphamvu yake. Akakonza, ngati kuzungulira kwa chitolirocho sikunayang'aniridwe panthawi yolimbitsa mabotolo, chitolirocho chikhoza kupindika kapena kugongana ndi ziwalo zina kuti chipange kukangana, motero kuchepetsa nthawi yogwira ntchito ya chitolirocho.
② Mukakonza chomangira cha payipi, ngati chamasuka kwambiri, kukangana ndi kugwedezeka kudzapangidwa pakati pa chomangira ndi payipi. Ngati chalimba kwambiri, pamwamba pa payipi, makamaka pamwamba pa payipi ya aluminiyamu, padzaphwanyidwa kapena kusokonekera, zomwe zimapangitsa kuti payipiyo iwonongeke ndikutuluka madzi.
③ Mukalimbitsa cholumikizira cha payipi, ngati mphamvu yake yapitirira mtengo womwe watchulidwa, pakamwa pa cholumikiziracho padzasweka, ulusi udzakokedwa kapena kuchotsedwa, ndipo ngozi yotulutsa mafuta idzachitika.
7. Kuwonongeka kapena kukalamba kwa payipi ya hydraulic
Kutengera ndi zaka zambiri zomwe ndakhala ndikugwira ntchito, komanso kuwona ndi kusanthula kusweka kwa mapaipi olimba a hydraulic, ndapeza kuti kusweka kwa mapaipi olimba kumachitika chifukwa cha kutopa, kotero payenera kukhala katundu wosinthana pa mapaipi. Pamene dongosolo la hydraulic likugwira ntchito, mapaipi a hydraulic amakhala ndi mphamvu yayikulu. Chifukwa cha mphamvu yosakhazikika, mphamvu yosinthana imapangidwa, zomwe zimapangitsa kuti pakhale zotsatira zosakanikirana za kugwedezeka, kusonkhana, kupsinjika, ndi zina zotero, zomwe zimapangitsa kuti pakhale kupsinjika kwakukulu mupaipi wolimba, kusweka kwa mapaipi, komanso kutayikira kwa mafuta.
Pa mapaipi a rabara, kukalamba, kuuma ndi kusweka kumachitika chifukwa cha kutentha kwambiri, kupanikizika kwambiri, kupindika kwambiri ndi kupotoka, ndipo pamapeto pake chitoliro cha mafuta chimaphulika ndi kutayikira kwa mafuta.
Mayankho
Pa vuto la kutayikira kwa mafuta lomwe limayambitsidwa ndi makina osindikizira a hydraulic, choyamba chomwe chimayambitsa kutayikira kwa mafuta chiyenera kudziwika, kenako yankho loyenera liyenera kupangidwa pa vuto lenilenilo.
(1) Sinthani zisindikizo
Zisindikizo zomwe zili mu makina osindikizira a hydraulic zikakalamba kapena kuwonongeka, ziyenera kusinthidwa pakapita nthawi. Izi zitha kuthetsa vuto la kutayikira kwa mafuta. Mukasintha zisindikizo, zisindikizo zapamwamba ziyenera kugwiritsidwa ntchito kuti zitsimikizire kudalirika kwa nthawi yayitali.
(2) Konzani mapaipi amafuta
Ngati vuto la kutayikira kwa mafuta layamba chifukwa cha mapaipi amafuta, mapaipi amafuta oyenera ayenera kukonzedwa. Mukakonza mapaipi amafuta, onetsetsani kuti ali olimba mokwanira ndipo gwiritsani ntchito zotsekera.
(3) Chepetsani kuchuluka kwa mafuta
Ngati mafuta ambiri, mafuta ochulukirapo ayenera kutulutsidwa kuti achepetse kuthamanga kwa madzi m'thupi. Kupanda kutero, kuthamangako kungayambitse mavuto otulutsa mafuta. Mukatulutsa mafuta ochulukirapo, muyenera kusamala kuti mafuta otayidwawo atayidwe bwino.
(4) Sinthani ziwalo zomwe zawonongeka
Zigawo zina mkati mwa makina osindikizira a hydraulic zikalephera, zigawozi ziyenera kusinthidwa pakapita nthawi. Izi zitha kuthetsa vuto la kutayikira kwa mafuta m'dongosolo. Mukasintha zigawo, zigawo zoyambirira ziyenera kugwiritsidwa ntchito kuti zitsimikizire kuti zikugwira ntchito bwino.
