Madzi a Hydraulic Hoseskapena Machitidwe ali paliponse, mumangofunika kudziwa komwe mungayang'ane.Ngati muwona migolo yomanga lalanje, ndiye inu'kuyang'ananso zida zodzaza ndi ma hydraulic system.Wotchetcha udzu wotembenuza zero?Inde.Galimoto ya zinyalala?Inde, kachiwiri.Mabuleki pagalimoto yanu, kupendekeka kwa mota yanu yakunja, pamalo opanga...ali paliponse.
Ma hydraulic hoses kapena makina amagwiritsa ntchito pressurized hydraulic fluid kuti atulutse ntchito pamakina.Tiyeni'Ndipita pazinsinsi zachangu.Hydraulic fluid ndi mafuta kapena madzi opangidwa ndi incompressible fluid.Popeza ndi incompressible, imatha kusamutsa mphamvu kuchokera ku mpope ndikuitumiza ku mota kapena silinda.Kuti mufotokoze chomwe ma hydraulic system ndi, tiyeni's kulankhula za yosavuta kwambiri: chipika splitter.Pampu imakoka madzimadzi kuchokera m'nkhokwe kudzera pamzere wobwerera ndikuukakamiza.Madzi opanikizidwa amatumizidwa kudzera pa payipi ya waya wa 2 ndikuchita pa silinda yokhala ndi mphero, kukankhira pa chipika mpaka chigawanika.Pamene pisitoni ikubwerera, silindayo imakankhira madzimadziwo kudzera pa hose yobwerera m'malo osungiramo madzi kuti azizire ndikukonzekera ulendo wotsatira.Dongosolo ili-posungira, pampu, silinda ndi payipi-ndi hydraulic system.
Hydraulic System
Kudziwa zambiri za dongosolo lanu kudzakuthandizani kusankha payipi yoyenera.Kusankha payipi ya hydraulic sikovuta mukangomaliza 'ndayamba kumvetsetsa zosankha zosiyanasiyana komanso chifukwa chake zilipo.
Kumbali imodzi, pali matani a ma hydraulic hose specs opangidwa ndi wopanga aliyense.Heck, pali 19 SAE 100R zolemba ndi zochepa za European EN specs.M'malo mwake, 's kwenikweni wokongola losavuta.Inu'Ndili ndi zosankha zitatu: mphira wokhala ndi mawaya achitsulo, thermoplastic yokhala ndi nsalu zolimbikitsira, kapena Teflon yokhala ndi mawaya osapangapanga.Pali zina zochulukirachulukira za ntchito kunja uko, ndipo ife 'tilankhula za iwo pang'ono, koma, kwenikweni, izi ndi zosankha zanu zitatu.Mutadziwa zomwe mukufuna, ena onse amadzipanga okha.
Tisanayambe, pali zinthu zina zomwe muyenera kuzidziwa.Choyamba, manambala a gawo la hydraulic hose amasonyeza mkati mwake pogwiritsa ntchito dongosolo la 1/16ths.Mwachitsanzo, -04 ndi 1/4''mkati mwake, kapena ID (4/16=1/4), ndi -12 ndi 1/4''(12/16=3/4) ndi zina zotero.Chifukwa chake, nambala yagawo ngati H28006 ndi hose spec H280 ndi kukula 06, kapena 3/8'' ID
Chotsatira, payipi ya hydraulic nthawi zambiri imayikidwa pachitetezo cha 4: 1.Izi zikutanthauza kuti payipi ya 3,000-psi imaphulika pa 12,000 psi kapena kuposa.Kupatulapo kumaphatikizapo jack hose yomwe nthawi zambiri imakhala ndi chitetezo cha 2: 1, chifukwa ndi ntchito yokhazikika komanso yotsika kwambiri.Funsani Ma Hose Pros athu ngati inu 'nkhawa za chitetezo factor.
Kapangidwe kake ka payipi ya hydraulic ndi chubu, reinforcement, ndi chivundikiro.Chubu ndi mkati mwa payipi yomwe imatumiza madzimadzi amadzimadzi.Ndiye pali kulimbikitsa;izi zimapereka mphamvu ndikusunga kupsinjika.Chomaliza ndi chophimba.Chivundikiro's ntchito ndi kuteteza kulimbikitsa ku abrasion ndi dzimbiri.
Mitundu Yomanga
Pali mitundu ikuluikulu itatu yomangirira mbali yakukakamiza ya hydraulic system ndi imodzi ya mbali yobwerera.Ma hoses a mbali yakukakamiza ya dongosolo lanu nthawi zambiri amakhala opangidwa ndi mphira, thermoplastic, kapena Teflon.
Mpira
Ma hydraulic hoses amapangidwa ndi mphira wa nitrile chifukwas yogwirizana ndi madzi ambiri a hydraulic.Mapaipi a mphira amatha kukhala ndi nsalu zomangira zomangira zotsika pansi pa 1,000 psi, kapena mawaya achitsulo olimba amphamvu mpaka 7,000 psi ndi kupitilira apo.Mitundu yowonjezereka ya waya ndiyo yofala kwambiri.Zomangamanga zimachokera ku gawo limodzi mpaka magawo asanu ndi limodzi olimbikitsa.
Zophimba nthawi zambiri zimapangidwa ndi mphira wopangidwa bwino kuti usasunthike ndi ma element ndi ma abrasion.Opanga ena amapanga mapaipi okhala ndi zovundikira zolimba kwambiri pazofunikira zomwe zimafunikira kutetezedwa koopsa;Izi zitha kukhala ndi zokutira za UHMW kuti zipirire kukwapula koopsa komanso kukhudzidwa.
Thermoplastic
Kumanga uku kumapangidwa ndi chubu cha nayiloni, chowonjezera cha fiber, komanso chivundikiro cha polyurethane.Thermoplastic hose nthawi zambiri imagwiritsidwa ntchito pama hydraulics wamba, kasamalidwe ka zinthu, ma forklift, komanso pafupi ndi magetsi.Imatha kuthana ndi zovuta zofananira ndi mapaipi awaya a 1- ndi 2 koma kuyikidwa m'malo omwe payipi ya rabara yokhala ndi mawaya sichingagwire ntchito.Chophimba cha polyurethane chimachita bwino kwambiri chikagwidwa ndi mtolo wa mtolo pa forklift.Nthawi zomwe magetsi amadetsa nkhawa, monga pokweza ndowa pokonza zingwe zamagetsi, payipi yosakhala ya conductive, thermoplastic ndi yabwino.
PTFE:
Wopangidwa ndi aPTFE chubu ndi zosapanga dzimbiri kuluka kulimbitsa, sichifuna chivundikiro chifukwa chotchinga chosapanga dzimbiri sichingawonongeke nthawi zonse.Teflon hose imagwiritsidwa ntchito pazinthu zomwe zimafuna kukana dzimbiri, kuyanjana ndi mankhwala, kapena komwe kutentha kumadetsa nkhawa.Imanyamula 450°F mlingo.
Zinthu zina zomwe muyenera kukumbukira pofotokozaPTFE payipi nkhawa kukula ndi kupindika utali wozungulira.Kukula kwake nthawi zambiri kumakhala 1/16''chocheperako kuposa nambala yagawo ikuwonetsa.Mwachitsanzo, -04 hose ndi 3/16''ndi -06 ndi 5/16''.Chifukwa chake, chifukwa chakuti gawo lanu limatha ndi 04 sizikutanthauza kuti payipi ndi 1/4''..Izi ndi zoona kwa masaizi onse.Ponena za bend radius, kumbukirani iziPTFE payipi ndi chubu cha pulasitiki cholimba chomwe chimakutidwa ndi luko.Mukapindika chubu chapulasitiki cholimba mpaka chikugwedezeka, mungakhale.tsopano ndawononga payipi yanu ndikupanga malo opanda mphamvu.Samalani poyenda m'malo othina.
Bwererani-Madzi a Hydraulic Hoses
Mzere wobwerera ndi payipi ya hydraulic yomwe imatha kuyamwa ndipo ikubwezeretsa madzimadzi a hydraulic kubwerera kumayambiriro kwa dongosolo.Kapangidwe ka payipi kameneka kamakhala ka chubu cha rabara ndipo chimakwirira ndi nsalu zoluka kuti ziwonjezeke bwino komanso waya woyamwa kuti azitha kuyamwa.
Hose ya Truck-Madzi a Hydraulic Hoses
Paipi yamagalimoto ndi gulu lake lapadera mkati mwa banja la hydraulic hose.SAE 100R5 imatanthauzira ngati chivundikiro cha nsalu, payipi ya waya wa 1 yomwe imagwiritsidwa ntchito pamakina ambiri pamagalimoto apamsewu.Monga payipi ya Teflon, kukula kwa payipi yamagalimoto sikutsata njira yokhazikika ya 1/16 yomwe imagwiritsidwa ntchito ndi payipi wamba wa hydraulic.ID yeniyeni ya hose ili paliponse kuchokera ku 1/16''to ⅛''zocheperako kutengera kukula.Apanso, itanani Hose Pros ku Besteflon, ndipo ife 'Ikuthandizani kumvetsetsa payipi ya 100R5.
Izi zikuphatikiza zoyambira zambiri zama hydraulic hoses.Ngati mungafunike kukumba mozama ndikulowa mu nitty gritty imbani imodzi mwama Hose Pros athuBesteflonndipo ife'ndidzakhala wokondwa kuthandiza.
Dinani batani pansipa kuti mufunse zambiri za PTFE hydraulic hoses.
