1. Kodi accumulator ndi chiyani
Hydraulic accumulator ndi chipangizo chosungira mphamvu.Mu accumulator, mphamvu yosungidwa imasungidwa mu mawonekedwe a gasi wothinikizidwa, kasupe woponderezedwa, kapena katundu wokwezedwa, ndipo amagwiritsa ntchito mphamvu kumadzi osadziwika bwino.
Accumulators ndi zothandiza kwambiri madzimadzi mphamvu kachitidwe.Amagwiritsidwa ntchito posungira mphamvu ndikuchotsa ma pulse.Atha kugwiritsidwa ntchito m'makina a hydraulic kuti achepetse kukula kwa pampu yamadzimadzi powonjezera pampu yamadzimadzi.Izi zimachitika posunga mphamvu mu mpope panthawi yomwe ikufunika kwambiri.Iwo akhoza kuchita monga slowdown ndi absorber wa kusinthasintha ndi pulses.Amatha kuletsa kuwomba ndikuchepetsa kugwedezeka komwe kumachitika chifukwa cha kuyambika kwadzidzidzi kapena kuyimitsidwa kwa silinda yamagetsi mumayendedwe a hydraulic.Madziwo akakhudzidwa ndi kukwera kwa kutentha ndi kugwa, cholumikizira chingagwiritsidwe ntchito kukhazikika kusintha kwamphamvu mu hydraulic system.Amatha kutulutsa madzi akapanikizika, monga mafuta ndi mafuta.

Pakalipano, ma accumulators omwe amagwiritsidwa ntchito kwambiri ndi mitundu ya pneumatic-hydraulic.Ntchito ya gasi ndi yofanana ndi kasupe wa buffer, imagwira ntchito ndi madzimadzi;mpweya umalekanitsidwa ndi pisitoni, diaphragm woonda kapena thumba mpweya.

2. Ntchito mfundo ya accumulator

Pansi pa kukakamizidwa, kusintha kwamadzimadzi (pansi pa kutentha kosalekeza) kumakhala kochepa kwambiri, kotero ngati palibe gwero lamagetsi (ndiko kuti, zowonjezera zamadzimadzi othamanga kwambiri), kuthamanga kwamadzimadzi kumatsika mofulumira. .

Kuthamanga kwa gasi kumakhala kwakukulu kwambiri, chifukwa gasiyo ndi yokhazikika, ngati kusintha kwakukulu kwa voliyumu, mpweyawo ukhoza kukhalabe ndi mphamvu zambiri.Choncho, pamene accumulator ikuwonjezera mafuta a hydraulic a hydraulic system, mpweya wothamanga kwambiri ukhoza kupitirizabe kusunga mphamvu ya mafuta a hydraulic pamene kuchuluka kwa madzi kwasintha.Zimakhala zazing'ono, zomwe zimapangitsa kuti mafuta a hydraulic achepetse kuthamanga msanga.

Ponena za nayitrogeni, chifukwa chachikulu ndikuti nayitrogeni ndi yokhazikika mwachilengedwe ndipo ilibe oxidation kapena kuchepetsa katundu.Izi ndizabwino kwambiri pakusunga magwiridwe antchito amafuta a hydraulic ndipo sizimayambitsa oxidation / kuchepetsa denaturation yamafuta a hydraulic!

Nayitrogeni ndiye kuthamanga kwa pre-charge, komwe kumayikidwa mu airbag ya accumulator ndikusiyanitsidwa ndi mafuta a hydraulic!Mukadzaza accumulator ndi mafuta a hydraulic, chifukwa cha kupanikizika kwa thumba la mpweya wa nayitrogeni pamafuta a hydraulic, ndiko kuti, kuthamanga kwamafuta a hydraulic ndikofanana ndi kuthamanga kwa nayitrogeni.Pamene mafuta a hydraulic akuthamangira mkati, thumba la mpweya wa nayitrogeni limaponderezedwa, ndipo mphamvu ya nayitrogeni imawonjezeka.Kuthamanga kwamafuta kumawonjezeka mpaka mafuta a hydraulic afika pakukakamiza kokhazikika!

Udindo wa accumulator ndikupereka kukakamiza kwina kwamafuta a hydraulic, omwe amapangidwa ndi mphamvu ya nayitrogeni!

3. Ntchito yaikulu ya accumulator

1. Kwa magetsi othandizira
Ma actuators a ma hydraulic systems amachita modumphadumpha ndipo nthawi yonse yogwira ntchito ndi yochepa kwambiri.Ngakhale ma actuators a ma hydraulic system samachita modukizadukiza, kuthamanga kwawo kumasiyana kwambiri mkati mwa kuzungulira kwa ntchito (kapena mkati mwa sitiroko).Pambuyo pa accumulator imayikidwa mu dongosolo lino, pampu yokhala ndi mphamvu yochepa ingagwiritsidwe ntchito kuchepetsa mphamvu ya galimoto yaikulu, kotero kuti dongosolo lonse la hydraulic ndi laling'ono, lolemera kwambiri, komanso lotsika mtengo.

2. Monga gwero lamphamvu ladzidzidzi
Kwa machitidwe ena, pompayo ikalephera kapena mphamvu ikulephera (mafuta opangira magetsi amasokonezedwa mwadzidzidzi), woyendetsa ayenera kupitiriza kukwaniritsa zofunikira.Mwachitsanzo, pofuna chitetezo, ndodo ya pistoni ya silinda ya hydraulic iyenera kubwezeredwa mu silinda.Pankhaniyi, accumulator yokhala ndi mphamvu zoyenerera imafunika ngati gwero lamphamvu ladzidzidzi.

3. Bweretsani kutayikira ndi kusunga kupanikizika kosalekeza
Kwa machitidwe omwe actuator sagwira ntchito kwa nthawi yayitali, koma kuti apitirizebe kupanikizika nthawi zonse, accumulator angagwiritsidwe ntchito kubwezera kutayikira, kotero kuti kupanikizika kumakhala kosalekeza.

4. Tengani hydraulic shock
Chifukwa cha kusintha kwadzidzidzi kwa njira yosinthira valavu, kuyimitsidwa kwadzidzidzi kwa pampu ya hydraulic, kuyimitsidwa kwadzidzidzi kwa kayendedwe ka actuator, kapenanso kufunikira kochita kupanga braking mwadzidzidzi kwa actuator, etc., madzi akuyenda mkati. payipi idzasintha kwambiri, zomwe zimapangitsa kuti pakhale kugwedezeka (kugunda kwamafuta).Ngakhale kuti pali valavu yotetezera m'dongosolo, sikutheka kutulutsa kuphulika kwa nthawi yochepa komanso kugwedeza kwamphamvu.Kupanikizika kodabwitsa kumeneku nthawi zambiri kumayambitsa kulephera kapena kuwonongeka kwa zida, zigawo, ndi zida zosindikizira mu dongosolo, kapena kuphulika kwa payipi, komanso kumapangitsa kuti dongosololi lipange kugwedezeka koonekeratu.Ngati accumulator imayikidwa pamaso pa gwero lamphamvu la valve yolamulira kapena hydraulic cylinder, kugwedezeka kungathe kutengeka ndikuchepetsedwa.

5. Tengani kugunda ndi kuchepetsa phokoso
Kuthamanga kwa pampu kumayambitsa kugunda kwamphamvu, kuchititsa kuthamanga kwamphamvu kwa actuator, kupangitsa kugwedezeka ndi phokoso.Lumikizani cholumikizira chodziwikiratu komanso chaching'ono cholumikizira molumikizana potuluka pampu kuti mutenge kuthamanga ndi kuthamanga ndikuchepetsa phokoso.
