1. Yintoni i-accumulator
I-hydraulic accumulator sisixhobo sokugcina amandla. Kwi-accumulator, amandla agciniweyo agcinwa ngendlela yegesi ecinezelweyo, intwasahlobo ecinezelweyo, okanye umthwalo ophakanyisiweyo, kwaye asebenzisa amandla kulwelo olungenakucinezelwa.
Ii-accumulators ziluncedo kakhulu kwiinkqubo zamandla olwelo. Zisetyenziselwa ukugcina amandla nokususa ii-pulses. Zingasetyenziswa kwiinkqubo ze-hydraulic ukunciphisa ubungakanani bepompo yolwelo ngokongeza ulwelo lwepompo. Oku kwenziwa ngokugcina amandla kwipompo ngexesha lesigaba semfuno ephantsi. Zingasebenza njengehla kunye nokufunxa ukuguquguquka kunye nee-pulses. Zinganciphisa ukubetheka kwaye zinciphise ukungcangcazela okubangelwa kukuqala okanye ukuyeka ngequbuliso kwesilinda yamandla kwisekethe ye-hydraulic. Xa ulwelo luchaphazeleka kukunyuka nokuwa kobushushu, i-accumulator ingasetyenziselwa ukuzinzisa utshintsho loxinzelelo kwinkqubo ye-hydraulic. Zingakhupha ulwelo phantsi koxinzelelo, njengegrisi kunye neoyile.

Okwangoku, ii-accumulators ezisetyenziswa kakhulu ziintlobo ze-pneumatic-hydraulic. Umsebenzi wegesi ufana ne-buffer spring, isebenza nolwelo; igesi yahlulwe yi-piston, i-diaphragm encinci okanye i-air bag.

2. Umgaqo wokusebenza we-accumulator

Phantsi kwesenzo soxinzelelo, utshintsho lomthamo wolwelo (phantsi kobushushu obungaguqukiyo) luncinci kakhulu, ngoko ke ukuba akukho mthombo wamandla (oko kukuthi, isongezelelo solwelo olunoxinzelelo oluphezulu), uxinzelelo lolwelo luya kwehla ngokukhawuleza.

Ukuqina kwegesi kukhulu kakhulu, kuba igesi inokucinezeleka, kwimeko yotshintsho olukhulu lomthamo, igesi isenokugcina uxinzelelo oluphezulu. Ke ngoko, xa i-accumulator isongeza ioyile ye-hydraulic yenkqubo ye-hydraulic, igesi enoxinzelelo oluphezulu inokuqhubeka nokugcina uxinzelelo lweoyile ye-hydraulic xa umthamo wolwelo utshintshile. Iba ncinci, nto leyo ebangela ukuba ioyile ye-hydraulic ilahlekelwe luxinzelelo ngokukhawuleza.

Ngokuphathelele i-nitrogen, isizathu esiphambili kukuba i-nitrogen izinzile ngokwendalo kwaye ayinazo iimpawu ze-oxidation okanye zokunciphisa. Oku kulungile kakhulu ekugcineni ukusebenza kwe-hydraulic oil kwaye akuyi kubangela i-oxidation/reduction denaturation ye-hydraulic oil!

I-nitrogen luxinzelelo lwangaphambi kokutshaja, olufakwa kwi-airbag ye-accumulator kwaye lwahlulwe kwi-hydraulic oil! Xa ugcwalisa i-accumulator nge-hydraulic oil, ngenxa yoxinzelelo lwe-nitrogen air bag kwi-hydraulic oil, oko kukuthi, uxinzelelo lwe-hydraulic oil lulingana noxinzelelo lwe-nitrogen. Njengoko i-hydraulic oil ingena ngokukhawuleza, i-nitrogen air bag iyacinezelwa, kwaye uxinzelelo lwe-nitrogen luyanda. Uxinzelelo lwe-oyile luyanda de i-hydraulic oil ifikelele kuxinzelelo olumiselweyo!

Indima ye-accumulator kukubonelela ngoxinzelelo oluthile lweoyile ye-hydraulic, eveliswa ngamandla e-nitrogen!

3. Umsebenzi ophambili we-accumulator

1. Ukubonelela ngombane oncedisayo
Ii-actuators zezinye iinkqubo ze-hydraulic zisebenza ngamaxesha athile kwaye ixesha lokusebenza lilonke lifutshane kakhulu. Nangona ii-actuators zezinye iinkqubo ze-hydraulic zingasebenzi ngamaxesha athile, isantya sazo siyahluka kakhulu ngaphakathi komjikelo wokusebenza (okanye ngaphakathi kwe-stroke). Emva kokuba i-accumulator ifakwe kule nkqubo, ipompo enamandla aphantsi ingasetyenziselwa ukunciphisa amandla e-main drive, ukuze yonke inkqubo ye-hydraulic ibe ncinci ngobukhulu, ilula ngobunzima, kwaye ingabizi kakhulu.

2. Njengomthombo wamandla ongxamiseko
Kwezinye iinkqubo, xa ipompo ingaphumeleli okanye umbane ungaphumeleli (ukunikezelwa kweoyile kwi-actuator kuphazamiseka ngequbuliso), i-actuator kufuneka iqhubeke nokugqiba amanyathelo afunekayo. Umzekelo, ukuze kukhuseleke, intonga yepiston yesilinda ye-hydraulic kufuneka ibuyiselwe kwisilinda. Kule meko, i-accumulator enomthamo ofanelekileyo iyadingeka njengomthombo wamandla ongxamisekileyo.

3. Gcwalisa ukuvuza kwaye ugcine uxinzelelo oluqhubekayo
Kwiinkqubo apho i-actuator ingasebenzi ixesha elide, kodwa ukuze igcine uxinzelelo oluqhubekayo, i-accumulator ingasetyenziselwa ukuhlawula ukuvuza, ukuze uxinzelelo luhlale luhleli.

4. Funxa uloyiko lwe-hydraulic
Ngenxa yokutshintsha ngesiquphe kwendlela ivalvu ejika umva, ukuyeka ngesiquphe kwepompo ye-hydraulic, ukuyeka ngesiquphe ukuhamba kwe-actuator, okanye kwanesidingo sokwenziwa sokubhuleka okungxamisekileyo kwe-actuator, njl.njl., ukuhamba kolwelo kumbhobho kuya kutshintsha kakhulu, okubangela uxinzelelo lokutshoka (ukubetha kweoyile). Nangona kukho ivalvu yokhuseleko kwinkqubo, kusenzima ukuvelisa ukunyuka kwexesha elifutshane kunye nokutshoka koxinzelelo. Olu xinzelelo lokutshoka ludla ngokubangela ukungaphumeleli okanye nokonakala kwezixhobo, izinto, kunye nezixhobo zokutywina kwinkqubo, okanye ukuqhekeka kombhobho, kwaye kukwabangela ukuba inkqubo ivelise ukungcangcazela okucacileyo. Ukuba i-accumulator ifakelwe phambi komthombo wokutshoka wevalvu yokulawula okanye isilinda ye-hydraulic, ukutshoka kunokufunxwa kwaye kuncitshiswe.

5. Funxa i-pulsation kwaye unciphise ingxolo
Ukuhamba kwepompo okutyhalayo kuya kubangela ukutyhalayo koxinzelelo, okubangela isantya sokunyakaza esingalinganiyo se-actuator, okubangela ukungcangcazela kunye nengxolo. Qhagamshela i-accumulator enobuthathaka nencinci ye-inertia ngaxeshanye kwindawo yokuphuma kwepompo ukuze ifunxe ukuhamba kunye nokutyhalala koxinzelelo kwaye inciphise ingxolo.
