Momwe Mungasankhire Mafuta a Hydraulic Moyenera pa Makina Osindikizira a Hydraulic

Makina osindikizira a hydraulic okhala ndi mizere inayi amapereka mafuta a hydraulic ku valavu pansi pa ntchito ya pampu ya mafuta. Dongosolo lowongolera limalamulira valavu iliyonse kuti mafuta a hydraulic amphamvu kwambiri afike m'zipinda zapamwamba ndi zapansi za silinda ya hydraulic, zomwe zimapangitsa kuti makina osindikizira a hydraulic asunthe. Makina osindikizira a hydraulic ndi chipangizo chomwe chimagwiritsa ntchito madzi kuti chitumize mphamvu.

Mafuta a hydraulic ndi ofunikira kwambiri pa makina osindikizira a hydraulic okhala ndi mizere inayi ndipo ndi imodzi mwa njira zofunika kwambiri zochepetsera kuwonongeka kwa makina. Kusankha mafuta oyenera a hydraulic kumagwirizana mwachindunji ndi nthawi ya ntchito ya makina a hydraulic.

Mukasankha mafuta a makina osindikizira a hydraulic okhala ndi mizere inayi, choyamba muyenera kusankha kukhuthala koyenera. Kusankha kukhuthala kwa mafuta kuyenera kuganizira mawonekedwe a kapangidwe kake, kutentha kogwirira ntchito ndi kupanikizika kwa ntchito kwa makina oyendetsera magetsi. Mu makina oyendetsera magetsi oyendetsera magetsi, pampu ya mafuta ndi imodzi mwa zigawo zomwe zimakhudzidwa kwambiri ndi kusintha kwa kukhuthala kwa mafuta a hydraulic. Mitundu yosiyanasiyana ya mapampu iliyonse imakhala ndi kukhuthala kocheperako komanso kovomerezeka. Kuti muchepetse kugwiritsa ntchito mphamvu, mafuta okhala ndi kukhuthala kochepa nthawi zambiri ayenera kugwiritsidwa ntchito momwe mungathere. Komabe, kuti mafuta ofunikira azilowetsedwa ndikuletsa kutuluka kwa madzi, mafuta a hydraulic okhala ndi kukhuthala koyenera ayenera kusankhidwa.

1. Kugawa Chitsanzo cha Mafuta a Hydraulic

Mitundu ya mafuta a hydraulic imagawidwa m'magulu atatu a dziko lonse: mtundu wa HL, mtundu wa HM, ndi mtundu wa HG.

(1) Mafuta a hydraulic amtundu wa HL amapangidwa kuchokera ku mafuta oyeretsedwa bwino komanso akuya kwambiri, kuphatikiza zowonjezera zotsutsana ndi dzimbiri komanso zotsutsana ndi dzimbiri. Malinga ndi kayendedwe ka madigiri 40 Celsius, kukhuthala kumatha kugawidwa m'magulu asanu ndi limodzi: 15, 22, 32, 46, 68, ndi 100.
(2) Mitundu ya HM imaphatikizapo alkaline yambiri, alkaline yochepa, neutral high zinc ndi mitundu yopanda phulusa. Malinga ndi kayendedwe ka madigiri 40 Celsius, kukhuthala kwa madzi kumagawidwa m'magulu anayi: 22, 32, 46, ndi 68.
(3) Mtundu wa HG uli ndi mphamvu zotsutsana ndi dzimbiri komanso zotsutsana ndi okosijeni. Kuphatikiza apo, chowonjezera cha viscosity index chimawonjezedwa, chomwe chili ndi makhalidwe abwino a viscosity-temperature.

2. Kugwiritsa Ntchito Mafuta a Hydraulic Model

(1) Mafuta a HL hydraulic amagwiritsidwa ntchito popaka mafuta m'mabokosi onyamula katundu ndi makina oyendera mpweya otsika mphamvu ya zida zosiyanasiyana zamakina komwe kulibe zofunikira zapadera za mafuta ndipo kutentha kwa malo ozungulira kuli pamwamba pa madigiri Celsius zero. Zogulitsa zotere nthawi zambiri zimakhala ndi kusinthasintha kwabwino kwambiri, ndipo kutentha kwakukulu kogwirira ntchito kumatha kufika madigiri Celsius 80.
(2) Mafuta a HM hydraulic amagwiritsidwa ntchito makamaka m'makina a hydraulic a mapampu olemera, apakati komanso amphamvu kwambiri, mapampu a plunger ndi mapampu a gear. Kuphatikiza apo, mafuta a hydraulic awa ndi oyeneranso zida zaukadaulo zapakati komanso mphamvu zambiri komanso makina a hydraulic a magalimoto.
(3) Mafuta a HG hydraulic ali ndi mphamvu zabwino zoletsa dzimbiri, zoletsa okosijeni, zoletsa kusweka, komanso zoletsa kutsetsereka, kotero ndi oyenera kwambiri machitidwe opaka mafuta omwe amagwiritsa ntchito ma hydraulic a zida zamakina ndi njanji zowongolera.

Kutentha kwa ntchito ya mafuta a hydraulic amitundu yosiyanasiyana ya viscosity pansi pa zofunikira zosiyanasiyana ndi motere.

Pali mitundu yambiri ya mafuta a hydraulic pamsika, ndipo palinso mitundu yambiri ya makina a hydraulic. Ngakhale kuti ntchito za mafuta a hydraulic ndizofanana, ndikofunikirabe kusankha mafuta osiyanasiyana a hydraulic pamakina osiyanasiyana a hydraulic. Posankha mafuta a hydraulic, ogwira ntchito ayenera kumvetsetsa zomwe akufunsidwa kuti achite, kenako kusankha mafuta oyenera a hydraulic pamakina a hydraulic.

Momwe Mungasankhire Mafuta Oyenera a Hydraulic Press

Njira ziwiri nthawi zambiri zimagwiritsidwa ntchito posankha mafuta a hydraulic. Njira imodzi ndi kusankha mafuta a hydraulic malinga ndi mitundu ya mafuta ndi zofunikira zomwe zimaperekedwa ndi zitsanzo kapena malangizo a wopanga makina osindikizira a hydraulic. Njira ina ndi kuganizira mozama za kusankha mafuta a hydraulic kutengera momwe makina a hydraulic alili, monga kuthamanga kwa ntchito, kutentha kwa ntchito, liwiro la kuyenda, mtundu wa zigawo za hydraulic ndi zina.

Posankha, ntchito zazikulu zomwe ziyenera kuchitika ndi izi: kudziwa kuchuluka kwa mafuta a hydraulic, kusankha mtundu woyenera wa mafuta a hydraulic, ndikukwaniritsa zosowa zapadera za makina a hydraulic.
Kawirikawiri amasankhidwa malinga ndi mfundo zotsatirazi:

(1) Malinga ndi mitundu yosiyanasiyana ya makina osindikizira a hydraulic

Makina olondola ndi makina wamba ali ndi zofunikira zosiyana za kukhuthala. Pofuna kupewa kusintha kwa ziwalo za makina chifukwa cha kukwera kwa kutentha ndikukhudza kulondola kwa ntchito, makina olondola ayenera kugwiritsa ntchito mafuta a hydraulic okhala ndi kukhuthala kochepa.

(2) Sankhani malinga ndi mtundu wa pampu ya hydraulic

Pampu ya hydraulic ndi gawo lofunika kwambiri la makina osindikizira a hydraulic. Mu makina osindikizira a hydraulic, liwiro lake loyenda, kupanikizika kwake ndi kukwera kwa kutentha zimakhala zambiri, ndipo nthawi yake yogwira ntchito ndi yayitali, kotero zofunikira pakukhuthala zimakhala zovuta kwambiri. Chifukwa chake pampu ya hydraulic iyenera kuganiziridwa posankha kukhuthala.

(3) Sankhani malinga ndi kuthamanga kwa ntchito kwa makina osindikizira a hydraulic

Ngati kuthamanga kuli kokwera, mafuta okhala ndi kukhuthala kwakukulu ayenera kugwiritsidwa ntchito kuti apewe kutayikira kwambiri kwa dongosolo komanso kugwira ntchito mopanda mphamvu. Ngati kuthamanga kogwira ntchito kuli kotsika, ndi bwino kugwiritsa ntchito mafuta okhala ndi kukhuthala kochepa, zomwe zingathandize kuchepetsa kutayika kwa kuthamanga.

(4) Ganizirani kutentha kwa malo ogwirira ntchito a makina osindikizira a hydraulic

Kukhuthala kwa mafuta a mchere kumasintha kwambiri chifukwa cha kutentha. Pofuna kuonetsetsa kuti kutentha kwa ntchito kuli koyenera, kutentha kwa malo ozungulira kuyeneranso kuganiziridwa.

(5) Ganizirani liwiro la kayendedwe ka magawo ogwirira ntchito a makina osindikizira a hydraulic

Pamene liwiro loyenda la ziwalo zogwirira ntchito mu dongosolo la hydraulic lili lalikulu kwambiri, kuchuluka kwa mafuta kumachepanso, kutayika kwa hydraulic kumawonjezeka mwachisawawa, ndipo kutuluka kwa madzi kumachepa pang'ono, kotero ndi bwino kugwiritsa ntchito mafuta omwe ali ndi kukhuthala kochepa.

(6) Sankhani mtundu woyenera wa mafuta a hydraulic

Kusankha mafuta a hydraulic kuchokera kwa opanga wamba kungathandize kuchepetsamakina osindikizira a hydraulickulephera ndi kukulitsa moyo wa makina osindikizira.
