1. Iyini i-accumulator
I-Hydraulic accumulator iyithuluzi lokugcina amandla.Ku-accumulator, amandla agciniwe agcinwa ngendlela yegesi ecindezelwe, intwasahlobo ecindezelwe, noma umthwalo ophakanyisiwe, futhi ifaka amandla oketshezini olungenakucindezelwa.
Ama-accumulators awusizo kakhulu ezinhlelweni zamandla eziwuketshezi.Zisetshenziselwa ukugcina amandla nokuqeda ama-pulses.Angasetshenziswa ezinhlelweni zamanzi ukuze kuncishiswe ubukhulu bepompo eliwuketshezi ngokwengeza uketshezi lwepompo.Lokhu kwenziwa ngokugcina amandla empompini ngesikhathi sesidingo esiphansi.Zingasebenza njengehlisa ukwehla kanye ne-absorber yokuguquguquka nama-pulses.Bangakwazi ukunqanda ukushaywa futhi banciphise ukudlidliza okubangelwa ukuqala noma ukuma kwesilinda samandla kumjikelezo we-hydraulic.Lapho uketshezi luthintwa ukukhuphuka nokuwa kwezinga lokushisa, i-accumulator ingasetshenziswa ukuze kunzinziswe izinguquko zengcindezi ohlelweni lwe-hydraulic.Bangakwazi ukukhipha uketshezi ngaphansi kwengcindezi, njengamafutha namafutha.

Njengamanje, ama-accumulators asetshenziswa kakhulu yizinhlobo ze-pneumatic-hydraulic.Umsebenzi wegesi ufana ne-buffer spring, usebenza ngoketshezi;igesi ihlukaniswe i-piston, i-diaphragm encane noma isikhwama somoya.

2. Umgomo wokusebenza we-accumulator

Ngaphansi kwesenzo sokucindezela, ukuguqulwa kwevolumu yoketshezi (ngaphansi kokushisa okungapheli) kuncane kakhulu, ngakho-ke uma kungekho mthombo wamandla (okungukuthi, isengezo se-high-pressure liquid), ingcindezi yoketshezi izokwehla ngokushesha. .

I-elasticity yegesi inkulu kakhulu, ngoba igesi iyacindezelwa, uma kwenzeka ushintsho olukhulu lwevolumu, igesi ingase igcine ingcindezi ephakeme kakhulu.Ngakho-ke, lapho i-accumulator ifaka uwoyela we-hydraulic wesistimu ye-hydraulic, igesi ephezulu yokucindezela ingaqhubeka nokugcina ukucindezela kwamafutha we-hydraulic lapho umthamo we-liquid ushintshile.Iba yincane, ibangele uwoyela we-hydraulic ulahlekelwe ukucindezela ngokushesha.

Ngokuqondene ne-nitrogen, isizathu esiyinhloko ukuthi i-nitrogen izinzile emvelweni futhi ayinayo izici ze-oxidation noma zokunciphisa.Lokhu kuhle kakhulu ekugcineni ukusebenza kwamafutha we-hydraulic futhi ngeke kubangele i-oxidation / ukunciphisa ukuchithwa kwamafutha we-hydraulic!

I-nitrogen iyingcindezi yangaphambi kokushaja, efakwa ku-airbag ye-accumulator futhi ihlukaniswe kuwoyela we-hydraulic!Uma ugcwalisa i-accumulator ngamafutha we-hydraulic, ngenxa yokucindezela kwesikhwama somoya we-nitrogen emafutheni we-hydraulic, okungukuthi, ukucindezela kwamafutha we-hydraulic kufana nokucindezela kwe-nitrogen.Njengoba uwoyela we-hydraulic egijima, isikhwama somoya se-nitrogen siyacindezelwa, futhi umfutho we-nitrogen uyanda.Umfutho kawoyela ukhuphuka kuze kube yilapho uwoyela we-hydraulic ufinyelela umfutho obekiwe!

Indima ye-accumulator ukuhlinzeka ngomfutho othile wamafutha we-hydraulic, okhiqizwa amandla e-nitrogen!

3. Umsebenzi oyinhloko we-accumulator

1. Ukuze uthole amandla asizayo
Ama-activator amanye amasistimu asebenza ngogesi asebenza ngezikhathi ezithile futhi isikhathi esiphelele sokusebenza sifushane kakhulu.Nakuba ama-activator ezinhlelo ezithile ze-hydraulic engasebenzi ngezikhathi ezithile, isivinini sawo siyahluka kakhulu phakathi komjikelezo wokusebenza (noma ngaphakathi kokushaywa unhlangothi).Ngemuva kokuthi i-accumulator ifakwe kulolu hlelo, iphampu enamandla aphansi ingasetshenziswa ukunciphisa amandla okushayela okuyinhloko, ukuze lonke uhlelo lwe-hydraulic luncane ngosayizi, lulula ngesisindo, futhi lungabizi.

2. Njengomthombo wamandla ophuthumayo
Kwezinye izinhlelo, lapho iphampu ihluleka noma amandla ehluleka (ukunikezwa kwamafutha ku-actuator kuphazamiseka ngokuzumayo), i-actuator kufanele iqhubeke nokuqedela izenzo ezidingekayo.Isibonelo, ukuze kuphephe, i-piston rod yesilinda esisebenza nge-hydraulic kufanele ihoxiswe kusilinda.Kulokhu, i-accumulator enamandla afanelekile iyadingeka njengomthombo wamandla ophuthumayo.

3. Gcwalisa ukuvuza futhi ugcine ingcindezi engapheli
Kuzinhlelo lapho i-actuator ingasebenzi isikhathi eside, kodwa ukuze kugcinwe ukucindezela okuqhubekayo, i-accumulator ingasetshenziswa ukunxephezela ukuvuza, ukuze ingcindezi ihlale njalo.

4. Gcoba ukushaqeka kwe-hydraulic
Ngenxa yokushintsha kungazelelwe kokuqondisa kwe-valve ehlehlayo, ukuma kungazelelwe kwepompo ye-hydraulic, ukuma kungazelelwe kokuhamba kwe-actuator, noma ngisho nesidingo sokwenziwa sokubhuleka okuphuthumayo kwe-actuator, njll., ukugeleza koketshezi ngaphakathi ipayipi izoshintsha kakhulu, okuholela ekucindezelekeni kokushaqeka (ukushaywa kwamafutha).Nakuba kune-valve yokuphepha ohlelweni, kusengenakugwemeka ukukhiqiza ukuqhuma kwesikhashana kanye nokushaqeka kokucindezela.Lokhu kucindezela kokushaqeka kuvame ukubangela ukwehluleka noma ngisho nokulimala kwamathuluzi, izingxenye, nemishini yokuvala ohlelweni, noma ukugqabuka kwepayipi, futhi iphinde ibangele isistimu ukuthi ikhiqize ukudlidliza okusobala.Uma i-accumulator ifakwe ngaphambi komthombo wokushaqeka wevalvu yokulawula noma isilinda esidonsa amanzi, ukushaqeka kungamuncwa futhi kuncishiswe.

5. Misa ukushaya kwenhliziyo futhi unciphise umsindo
Ukugeleza kwe-pulsating kwepompo kuzodala ukucindezela kokucindezela, kubangele isivinini sokunyakaza esingalingani se-actuator, kubangele ukudlidliza nomsindo.Xhuma i-accumulator ye-inertia ezwelayo nencane ngokuhambisana endaweni yokuphuma yepompo ukuze ubambe ukugeleza nokushaya kwengcindezi futhi unciphise umsindo.
