Chifukwa Chake Mini Excavators Amataya Mphamvu Yokumba: Buku Lothandizira Kuzindikira Hydraulic

Tangoganizirani izi: galimoto yanu yaying'ono yofukula inali kukumba ngalande mosangalala m'mawa wonse. Kenako mwadzidzidzi chidebecho chinakumana ndi kukana ndipo chinkachita ngati supuni yogona mu batala wozizira. Injini imamveka bwino, ma joysticks amasuntha, koma mphamvu yofukula ikuoneka kuti yapita ku tchuthi.

Ngati munadzifunsapo chifukwa chake ma mini excavator amataya mphamvu yakukumba , yankho nthawi zambiri limakhala kwinakwake mkati mwa dongosolo la hydraulic m'malo mwa chidebe kapena kulumikizana. Ma mini excavator amadalira mphamvu ya hydraulic kuti asinthe mphamvu ya injini kukhala mphamvu yeniyeni yakukumba. Mphamvu ikatsika, mphamvu imatha.

Bukuli likufotokoza vutoli m'njira yosavuta ya uinjiniya: momwe mphamvu yofukula imapangidwira, zomwe zigawo zake nthawi zambiri zimalephera poyamba, komanso momwe akatswiri amapezera vuto popanda kusintha theka la makina chifukwa cha kukhumudwa.

Kodi kwenikweni n’chiyani chimapangitsa kuti kukumba kukhale ndi mphamvu mu Mini Excavator?

Musanatsatire zolakwika, zimathandiza kumvetsetsa komwe mphamvu yokumba imachokera. Chodabwitsa n'chakuti sizikugwirizana kwenikweni ndi mano a ndowa koma zimakhudza kwambiri kuthamanga kwa mafuta.

Mkati mwa chofukula chaching'ono, mphamvu yokumba imatsatira unyolo wowongoka:

injini → pampu yamadzimadzi → mafuta opanikizika → valavu yowongolera → masilinda → mphamvu ya chidebe

Ngati chilichonse chikugwira ntchito bwino, mafuta a hydraulic amakankhira ma silinda a boom, arm ndi bucket ndi mphamvu yayikulu. Ngakhale chofukula chaching'ono chingapangitse matani angapo a mphamvu yophulika.

Zinthu zitatu zaukadaulo zimatsimikiza mphamvu ya mphamvu imeneyo:

• kuthamanga kwamadzimadzi

• kuchuluka kwa kayendedwe ka madzi

• kusindikiza bwino kwa silinda

Pamene chilichonse mwa zitatuzi chikugwa, mphamvu yokumba imagwa nayo.

Kodi Mungadziwe Bwanji Ngati Pumpu ya Hydraulic Ikuchepa Mphamvu?

Pampu ya hydraulic imagwira ntchito ngati mtima wa makina. Imazungulira mafuta opanikizika ku gawo lililonse logwira ntchito.

Pambuyo pa maola ambirimbiri ogwirira ntchito, ziwalo zamkati zimayamba kutha. Ma pistoni, ma valve plates ndi ma bearing pang'onopang'ono amataya mphamvu zawo zolimba. Izi zikachitika, mafuta amatuluka mkati mwa pampu m'malo mopita ku masilinda.

Zotsatira zake zimamveka motere:

• boom imakwera pang'onopang'ono ikanyamula katundu

• Chidebecho chikuvutika kulowa m'nthaka yolimba

• ntchito zambiri nthawi imodzi zimakhala zochedwa

Katswiri nthawi zambiri amatsimikiza kuti pampu yatha polumikiza choyezera kuthamanga kwa mpweya ku doko loyesera la hydraulic. Ngati kuthamanga sikungafike pamlingo womwe watchulidwa, pampuyo ikhoza kukhala chifukwa.

Mwachidule, pompu ikuzungulirabe, koma mafuta akugwiritsa ntchito njira zazifupi mkati m'malo mogwira ntchito yothandiza.

Kodi Valavu Yothandizira Kupanikizika Ikubera Mphamvu Yanu Yokumba?

Dongosolo lililonse la hydraulic lili ndi valavu yochepetsera kupanikizika. Ntchito yake ndikuletsa kupanikizika kwambiri komwe kungawononge zigawo zake.

Komabe, ngati valavu imeneyo yatsegulidwa msanga kwambiri, imagwira ntchito ngati chotchingira kuthamanga kwa mpweya.

Tangoganizirani kuyesa kupopera tayala pamene wina akutsegula valavu mwakachetechete nthawi yomweyo. Pampu ya mpweya imagwirabe ntchito, koma mphamvu siimakula.

Izi zikachitika mu excavator, ogwiritsa ntchito nthawi zambiri amazindikira:

• mphamvu yofooka yokumba pa ntchito zonse

• makinawo amaima asanafike nthawi yodzaza ndi chidebe

• kutentha kwa mafuta a hydraulic kumawonjezeka panthawi yogwira ntchito

Kuyesa kwa pressure gauge kumavumbula vutoli mwachangu. Ngati pressure ya system ikadali yotsika kuposa momwe imafunikira ngakhale ikalemera kwambiri, valavu yothandiza iyenera kusamalidwa.

Kodi Chimachitika N'chiyani Ma Silinda a Hydraulic Akatuluka Mkati?

Masilinda a hydraulic amapanga mphamvu yeniyeni yokumba. Mkati mwa silinda iliyonse muli pistoni yokhala ndi mphete zotsekera zomwe zimalekanitsa mbali ya kuthamanga kwambiri ndi mbali ya kuthamanga kochepa.

Pakapita nthawi zisindikizo zimenezo zimatha. Zikatero, mafuta amadutsa pa pistoni m'malo moikankhira patsogolo.

Kuchokera pampando wa woyendetsa, izi nthawi zambiri zimawoneka ngati:

• boom ikumira pang'onopang'ono pamene ikunyamula katundu

• chidebecho chikupindika kumbuyo pokankhira dothi

• mphamvu yofukula yachepa ngakhale kuti injini imathamanga bwino

Akatswiri amachita mayeso osavuta: gwirani chowongoleracho mosasunthika ndikuwona ngati silinda ikugwedezeka. Ngati ikuyenda pamene iyenera kukhala chete, mwina kutuluka kwa mkati kungachitike.

Taganizirani izi ngati njira yochepetsera mafuta: mafutawo amatenga njira yosavuta m'malo mogwira ntchito.

Kodi Mafuta Odetsedwa a Hydraulic Angayambitse Kukumba Mofooka?

Inde. Mafuta a hydraulic si madzi okha, koma ndi njira yomwe imanyamula mphamvu m'dongosolo lonse.

Pamene kuipitsidwa kwalowa m'thupi, zinthu zingapo zimayamba kuchitika:

• ma valve amamatira

• zida zopopera zimawonongeka mwachangu

• kutayikira kwamkati kumawonjezeka

Kuipitsidwa nthawi zambiri kumachitika m'njira zitatu:

• fumbi lolowera kudzera m'zisindikizo zowonongeka

• tinthu tachitsulo tomwe timapangidwa ndi kuvala kwa zigawo

• madzi ochokera ku condensation

Kuipitsidwa kukafalikira m'dongosolo, magwiridwe antchito amachepa pang'onopang'ono. Chofukula chingagwirebe ntchito, koma mphamvu yofukula imachepa pang'onopang'ono.

Kusanthula mafuta nthawi zonse kumathandiza akatswiri kuzindikira mavutowa makina asanayambe kufooka.

Kodi Mpweya mu Dongosolo la Hydraulic Ungachepetse Mphamvu Yokumba?

Makina a hydraulic amagwira ntchito bwino akadzazidwa ndi mafuta onse. Ma thovu a mpweya amachita mosiyana kwambiri ndi madzi a hydraulic.

Mafuta amatumiza mphamvu mwachindunji. Mpweya umapanikizika.

Ngati mpweya ulowa m'dongosolo kudzera m'mapayipi otayirira kapena mafuta ochepa, makinawo angasonyeze zizindikiro monga:

• kayendedwe ka ndowa yogwedezeka

• yankho losasinthasintha la kukumba

• kutayika kwa mphamvu kwakanthawi panthawi yokumba kwambiri

Kuchotsa mpweya wotsekeredwa ndi kukonza kutayikira kwa mpweya nthawi zambiri kumabwezeretsa khalidwe labwinobwino.

Kodi Injini Imayambitsa Kutayika kwa Mphamvu Yokumba?

Ngakhale kuti makina a hydraulic amapanga mphamvu yokumba, injini imapereka mphamvu kumbuyo kwake.

Ngati mphamvu ya injini yatsika, mphamvu ya hydraulic imatha kutsatizana.

Zifukwa zomwe zimafala kwambiri chifukwa cha injini ndi izi:

• zosefera zamafuta zotsekedwa

• mpweya wochepa wolowa

• kuvala kwa jakisoni

• kuchepetsa kupsinjika

Makina ofukula amakono nthawi zambiri amagwiritsa ntchito injini za dizilo kuchokera kwa opanga monga Yanmar kapena Kubota. Mphamvu ya injini ikatsika ikatsika, pampu ya hydraulic imachepa ndipo kuthamanga kwa mpweya kumachepa.

Akatswiri asanachotse zida zamagetsi, nthawi zambiri amatsimikiza kuti injini ikhoza kusungabe RPM yoyesedwa pansi pa katundu wogwiritsidwa ntchito.

Njira Yothandiza Yodziwira Matenda Yomwe Akatswiri Amagwiritsa Ntchito

Akatswiri odziwa bwino ntchito yawo sadziwa kawirikawiri. M'malo mwake, amatsatira dongosolo loyenera loyang'anira lomwe limaletsa kukonza kosafunikira.

1. Yang'anani momwe injini ikuyendera komanso RPM yovomerezeka.

2. Yesani kuthamanga kwa madzi pogwiritsa ntchito njira yoyesera.

3. Yang'anani kuchuluka kwa mafuta a hydraulic ndi kuipitsidwa kwake.

4. Yang'anani ngati masilinda amayendayenda pansi pa katundu.

5. Yang'anani momwe ma valve opumulira amakhalira ndi ma hydraulic filters amagwirira ntchito.

Kutsatira ndondomekoyi kumachepetsa vutoli mwachangu. Mavuto ambiri okhudzana ndi kukumba mphamvu amatha kupezeka m'malo amodzi mwa awa popanda kusokoneza kwakukulu.

Mapeto

Pamene chofukula chaching'ono chikumva kufooka mwadzidzidzi, makinawo nthawi zambiri "amasweka" m'njira yovuta kwambiri. Nthawi zambiri, gawo la hydraulic limataya mphamvu pang'onopang'ono. Kuwonongeka kwa pampu, mavuto a valavu yothandizira kupanikizika, kutuluka kwa silinda kapena mafuta a hydraulic oipitsidwa ndizomwe zimayambitsa nthawi zambiri pamene zofukula zazing'ono zimataya mphamvu yakukumba.

Kumvetsetsa momwe kuthamanga kwa madzi, kuyenda kwa madzi, ndi kutsekeka kwa madzi kumagwirira ntchito kumathandiza akatswiri kuzindikira vutoli mwanzeru m'malo mosintha ziwalo mwachimbulimbuli. Chimene chimayambitsa vutoli chikadziwika, kubwezeretsa mphamvu ya madzi moyenera nthawi zambiri kumabwezeretsa mphamvu yake yokumba.

Mafunso Ofunsidwa Kawirikawiri - Mavuto a Mphamvu Yokumba Mini Excavator

Kodi ma mini excavator nthawi zambiri amagwiritsa ntchito mphamvu ya hydraulic yotani?

Makina ambiri ofukula zinthu ang'onoang'ono amagwira ntchito pakati pa mipiringidzo 200 ndi 350 kutengera kukula kwa makina ndi kapangidwe ka hydraulic.

N’chifukwa chiyani chofukula changa chimakumba bwino mu nthaka yofewa koma chimavutika mu nthaka yopapatiza?

Dothi lolimba limafuna mphamvu yochulukirapo ya silinda. Ngati mphamvu ya hydraulic ili pansi pang'ono pa zomwe zafotokozedwa, vutoli limawonekera pokhapokha ngati mukukumba zinthu zovuta.

Kodi zosefera za hydraulic zotsekeka zingayambitse kutayika kwa magetsi?

Inde. Zosefera zoletsedwa zimachepetsa kuyenda kwa mafuta kufika pampope, zomwe zimachepetsa kutulutsa kwa hydraulic ndikuchepetsa kuyenda kwa actuator.

Kodi mafuta a hydraulic ayenera kuyesedwa kangati?

Ma ndandanda ambiri okonza amalimbikitsa kuti aziyang'aniridwa maola 500 aliwonse ogwirira ntchito, ngakhale kuti kusanthula mafuta kungatalikitse kapena kufupikitsa nthawi yosinthira kutengera momwe zinthu zilili.
