1. Yintoni i-accumulator
I-Hydraulic accumulator sisixhobo sokugcina amandla.Kwi-accumulator, amandla agciniweyo agcinwa ngendlela yegesi ecinezelweyo, intwasahlobo ecinezelweyo, okanye umthwalo ophakanyisiweyo, kwaye isebenzise amandla kulwelo olungenakuthintelwa.
Ii-accumulators ziluncedo kakhulu kwiinkqubo zamandla alwelo.Zisetyenziselwa ukugcina amandla kunye nokuphelisa i-pulses.Zingasetyenziselwa kwiinkqubo ze-hydraulic ukunciphisa ubungakanani bempompo yamanzi ngokuncedisa i-pump fluid.Oku kwenziwa ngokugcina amandla kwimpompo ngexesha lenqanaba lemfuno ephantsi.Zingasebenza njenge-slowdown kunye ne-absorber yokuguquguquka kunye ne-pulses.Bangakwazi ukuthintela ukuvuthela kunye nokunciphisa ukungcangcazela okubangelwa ukuqala ngokukhawuleza okanye ukumisa isilinda samandla kwisekethe ye-hydraulic.Xa i-liquid ichaphazeleka ngokunyuka kweqondo lokushisa kunye nokuwa, i-accumulator ingasetyenziselwa ukuzinzisa utshintsho loxinzelelo kwinkqubo ye-hydraulic.Ziyakwazi ukukhupha ulwelo phantsi koxinzelelo, njengegrisi neoli.

Okwangoku, ii-accumulators ezisetyenziswa ngokuqhelekileyo ziintlobo ze-pneumatic-hydraulic.Umsebenzi wegesi ufana ne-buffer spring, isebenza ngolwelo;Irhasi yahlulwe ngepiston, idiaphragm encinci okanye ibhegi yomoya.

2. Umgaqo wokusebenza we-accumulator

Ngaphantsi kwesenzo soxinzelelo, utshintsho lwevolumu yolwelo (phantsi kobushushu obuqhubekayo) buncinci kakhulu, ngoko ke ukuba akukho mthombo wamandla (oko kukuthi, ukongezwa kwe-high-pressure liquid), uxinzelelo lolwelo luya kuhla ngokukhawuleza. .

I-elasticity yegesi inkulu kakhulu, kuba igesi iyanyanzeliswa, kwimeko yokutshintsha umthamo omkhulu, igesi isenokuthi igcine uxinzelelo oluphezulu.Ngoko ke, xa i-accumulator yongezelela ioli ye-hydraulic ye-hydraulic system, i-gas ephezulu yoxinzelelo inokuqhubeka nokugcina uxinzelelo lweoli ye-hydraulic xa umthamo we-liquid utshintshile.Iba yincinci, ibangela ukuba ioli ye-hydraulic ilahlekelwe uxinzelelo ngokukhawuleza.

Ngokuphathelele i-nitrogen, isizathu esona sizathu kukuba i-nitrogen izinzile kwindalo kwaye ayinayo i-oxidation okanye iipropati zokunciphisa.Oku kuhle kakhulu ekugcineni ukusebenza kweoli ye-hydraulic kwaye ayiyi kubangela i-oxidation / ukunciphisa i-denaturation yeoli ye-hydraulic!

I-nitrojeni yingcinezelo yangaphambili, efakwe kwi-airbag ye-accumulator kwaye ihlukaniswe kwioli ye-hydraulic!Xa ugcwalisa i-accumulator ngeoli ye-hydraulic, ngenxa yoxinzelelo lwe-nitrogen air bag kwioli ye-hydraulic, oko kukuthi, uxinzelelo lweoli ye-hydraulic ilingana noxinzelelo lwe-nitrogen.Njengoko ioli ye-hydraulic ikhawuleza, isikhwama somoya se-nitrogen sixinzelelwe, kwaye uxinzelelo lwe-nitrogen luyanda.Uxinzelelo lweoyile luyanda de ioyile yehydraulic ifikelele kuxinzelelo olubekiwe!

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

3. Umsebenzi ophambili we-accumulator

1. Ukubonelela ngombane oncedisayo
Ii actuators zezinye iinkqubo zamanzi aphantsi komhlaba zisebenza ngamaxesha athile kwaye ixesha elipheleleyo lokusebenza lifutshane kakhulu.Nangona ii-activators zezinye iinkqubo ze-hydraulic zingasebenzi ngokukhawuleza, isantya sazo siyahluka kakhulu kumjikelo wokusebenza (okanye ngaphakathi kwe-stroke).Emva kokuba i-accumulator ifakwe kule nkqubo, ipompo enegunya eliphantsi ingasetyenziselwa ukunciphisa amandla omqhubi oyintloko, ukwenzela ukuba yonke inkqubo ye-hydraulic incinci ngobukhulu, ilula ngesisindo, kwaye ingabizi.

2. Njengomthombo wamandla kaxakeka
Kwezinye iinkqubo, xa ipompo ihluleka okanye amandla ahluleka (ukunikezelwa kweoli kwi-activator ngokukhawuleza kuphazamisekile), i-actuator kufuneka iqhubeke nokugqiba izenzo eziyimfuneko.Ngokomzekelo, ukwenzela ukhuseleko, intonga yepiston ye-hydraulic cylinder kufuneka ihoxiswe kwi-cylinder.Kule meko, i-accumulator enomthamo ofanelekileyo iyafuneka njengomthombo wamandla kaxakeka.

3. Gcwalisa ukuvuza kwaye ugcine uxinzelelo oluqhubekayo
Kwiinkqubo apho i-actuator ingasebenzi ixesha elide, kodwa ukugcina uxinzelelo oluqhubekayo, i-accumulator ingasetyenziselwa ukuhlawulela ukuvuza, ukwenzela ukuba uxinzelelo luhlala luhleli.

4. Funxa umothuko wehydraulic
Ngenxa yokutshintsha ngesiquphe kwesalathiso sevalve ebuyela umva, ukumisa ngequbuliso kwempompo ye-hydraulic, ukuyeka ngequbuliso ukuhamba kwe-actuator, okanye imfuno eyenziweyo yokuqhawuka okungxamisekileyo kwe-actuator, njl. njl., ukuhamba kolwelo ngaphakathi umbhobho uya kutshintsha ngokukhawuleza, okukhokelela kuxinzelelo lomothuko (i-oil hit).Nangona kukho i-valve yokukhusela kwinkqubo, kusengenakuphepheka ukuvelisa ukutshatyalaliswa kwexesha elifutshane kunye nokutshatyalaliswa koxinzelelo.Olu xinzelelo lothusayo luhlala lubangela ukusilela okanye nokonakala kwezixhobo, amacandelo, kunye nezixhobo zokutywina kwinkqubo, okanye ukugqabhuka kombhobho, kwaye kukwabangela ukuba inkqubo ivelise ukungcangcazela okucacileyo.Ukuba i-accumulator ifakwe phambi komthombo wothuso wevalve yokulawula okanye i-hydraulic cylinder, umothuko unokufunxwa kwaye uncitshiswe.

5. Funxa i-pulsation kwaye unciphise ingxolo
Ukuhamba kwe-pulsating yempompo kuya kubangela ukubethelwa koxinzelelo, kubangele isantya sokunyakaza esingalinganiyo se-actuator, kubangela ukungcangcazela kunye nengxolo.Qhagamshela i-accumulator ebuthathaka kunye nencinci ye-inertia ngokuhambelana kwindawo yokuphuma yempompo ukufunxa ukuhamba kunye noxinzelelo lwe-pulsations kunye nokunciphisa ingxolo.
