1. Kuyini i-accumulator
I-hydraulic accumulator iyithuluzi lokugcina amandla. Ku-accumulator, amandla agciniwe agcinwa ngesimo segesi ecindezelwe, isiphethu esicindezelwe, noma umthwalo ophakanyisiwe, futhi asebenzisa amandla oketshezini olungacindezelwe kakhulu.
Ama-accumulator awusizo kakhulu ezinhlelweni zamandla oketshezi. Asetshenziselwa ukugcina amandla nokususa ama-pulse. Angasetshenziswa ezinhlelweni zama-hydraulic ukunciphisa usayizi wephampu yoketshezi ngokufaka uketshezi lwephampu. Lokhu kwenziwa ngokugcina amandla ephampu ngesikhathi sesigaba sokufunwa okuphansi. Angasebenza njengokunciphisa ijubane kanye nokumunca ukuguquguquka nama-pulse. Anganciphisa ukushaywa futhi anciphise ukudlidliza okubangelwa ukuqala noma ukuma okungazelelwe kwesilinda samandla kusekethe ye-hydraulic. Lapho uketshezi luthintwa ukwenyuka nokwehla kwezinga lokushisa, i-accumulator ingasetshenziswa ukuzinzisa izinguquko zokucindezela ohlelweni lwe-hydraulic. Angakhipha uketshezi ngaphansi kwengcindezi, njengamafutha namafutha.

Njengamanje, ama-accumulator asetshenziswa kakhulu yizinhlobo ze-pneumatic-hydraulic. Umsebenzi wegesi ufana nesipilingi se-buffer, usebenza noketshezi; igesi ihlukaniswa yi-piston, i-diaphragm encane noma isikhwama somoya.

2. Isimiso sokusebenza se-accumulator

Ngaphansi kwesenzo sokucindezela, ushintsho lwevolumu yoketshezi (ngaphansi kokushisa okungaguquki) luncane kakhulu, ngakho-ke uma kungekho mthombo wamandla (okungukuthi, isengezo soketshezi olunomfutho ophezulu), umfutho woketshezi uzokwehla ngokushesha.

Ukuqina kwegesi kukhulu kakhulu, ngoba igesi iyacindezeleka, uma kwenzeka ushintsho olukhulu lwevolumu, igesi ingase isalondoloze ingcindezi ephezulu. Ngakho-ke, lapho i-accumulator ifaka uwoyela we-hydraulic wesistimu ye-hydraulic, igesi enomfutho ophezulu ingaqhubeka nokugcina ingcindezi kawoyela we-hydraulic lapho ivolumu yoketshezi isishintshile. Iba ncane, okwenza uwoyela we-hydraulic ulahlekelwe ingcindezi ngokushesha.

Ngokuphathelene ne-nitrogen, isizathu esiyinhloko ukuthi i-nitrogen izinzile ngokwemvelo futhi ayinazo izakhiwo ze-oxidation noma zokunciphisa. Lokhu kuhle kakhulu ekugcineni ukusebenza kukawoyela we-hydraulic futhi ngeke kubangele ukuwohloka/ukuncipha kukawoyela we-hydraulic!

I-nitrogen ingcindezi yangaphambi kokushaja, efakwa esikhwameni somoya se-accumulator futhi ihlukaniswe namafutha e-hydraulic! Uma ugcwalisa i-accumulator ngamafutha e-hydraulic, ngenxa yokucindezela kwesikhwama somoya se-nitrogen kumafutha e-hydraulic, okungukuthi, ingcindezi yamafutha e-hydraulic ilingana nengcindezi ye-nitrogen. Njengoba uwoyela we-hydraulic ungena ngokushesha, isikhwama somoya se-nitrogen siyacindezelwa, futhi ingcindezi ye-nitrogen iyanda. Ingcindezi yamafutha iyanda kuze kube yilapho uwoyela we-hydraulic ufinyelela ingcindezi ebekiwe!

Indima ye-accumulator ukuhlinzeka ngengcindezi ethile kawoyela we-hydraulic, ekhiqizwa ngamandla e-nitrogen!

3. Umsebenzi oyinhloko we-accumulator

1. Ukunikezwa kwamandla okusiza
Ama-actuator ezinhlelo ezithile ze-hydraulic asebenza ngezikhathi ezithile futhi isikhathi sokusebenza sifushane kakhulu. Nakuba ama-actuator ezinhlelo ezithile ze-hydraulic engasebenzi ngezikhathi ezithile, isivinini sawo siyahlukahluka kakhulu ngaphakathi komjikelezo wokusebenza (noma ngaphakathi kokushaya kwenhliziyo). Ngemva kokufakwa kwe-accumulator kulolu hlelo, iphampu enamandla aphansi ingasetshenziswa ukunciphisa amandla edrayivu enkulu, ukuze lonke uhlelo lwe-hydraulic lube luncane ngobukhulu, lube lula ngesisindo, futhi lungabizi.

2. Njengomthombo wamandla ophuthumayo
Kwezinye izinhlelo, lapho iphampu ihluleka noma ugesi uphela (ukunikezwa kukawoyela ku-actuator kuphazamiseka ngokuzumayo), i-actuator kufanele iqhubeke nokuqedela izenzo ezidingekayo. Isibonelo, ukuze kuphephe, induku yepiston yesilinda se-hydraulic kumele ibuyiselwe emuva ku-cylinder. Kulesi simo, i-accumulator enamandla afanele iyadingeka njengomthombo wamandla ophuthumayo.

3. Gcwalisa kabusha ukuvuza futhi ugcine ingcindezi engaguquki
Ezinhlelweni lapho i-actuator ingasebenzi isikhathi eside, kodwa ukuze igcine ingcindezi engaguquki, i-accumulator ingasetshenziswa ukukhokhela ukuvuza, ukuze ingcindezi ihlale ingaguquki.

4. Munca ukushaqeka kwe-hydraulic
Ngenxa yokushintsha okungazelelwe kwendlela ivalvu yokubuyisela emuva, ukuma okungazelelwe kwephampu ye-hydraulic, ukuma okungazelelwe kokunyakaza kwe-actuator, noma ngisho nesidingo sokwenziwa sokubhuleka okuphuthumayo kwe-actuator, njll., ukugeleza koketshezi epayipini kuzoshintsha kakhulu, okuholela ekucindezelweni kokushaqeka (ukushaya kukawoyela). Nakuba kukhona ivalvu yokuphepha ohlelweni, kusese yinto engenakugwenywa ukukhiqiza ukukhuphuka kwesikhashana kanye nokushaqeka kwengcindezi. Lokhu kucindezela kokushaqeka kuvame ukubangela ukwehluleka noma ngisho nomonakalo wezinsimbi, izingxenye, kanye namadivayisi okuvala ohlelweni, noma ukuqhekeka kwepayipi, futhi kubangele nokuthi uhlelo lukhiqize ukudlidliza okusobala. Uma i-accumulator ifakwa ngaphambi komthombo wokushaqeka wevalvu yokulawula noma isilinda ye-hydraulic, ukushaqeka kungamuncwa futhi kuncishiswe.

5. Munca ukushaya kwenhliziyo futhi wehlise umsindo
Ukugeleza kwephampu okugobhozayo kuzobangela ukushaya kwengcindezi, okubangela isivinini sokunyakaza esingalingani se-actuator, okubangela ukudlidliza nomsindo. Xhuma i-accumulator ebucayi nencane ye-inertia ngesikhathi esifanayo endaweni yokukhipha iphampu ukuze umunce ukugeleza nokushaya kwengcindezi futhi unciphise umsindo.
