Ukukhetha i-valve ye-hydraulic eyiyo yimeko ebalulekileyo yokwenza inkqubo ye-hydraulic ibe nengqiqo ekuyilweni, egqwesileyo kwintsebenzo yezobugcisa kunye nezoqoqosho, kulula ukuyifaka kunye nokugcina, kunye nokuqinisekisa ukusebenza okuqhelekileyo kwenkqubo.Ngenxa yokuba ukukhethwa kwe-valve ye-hydraulic ichanekile okanye akunjalo, inobudlelwane obukhulu kunye nempumelelo okanye ukungaphumeleli kwenkqubo, ngoko kufuneka kuthathwe ngokungathí sina.
Imigaqo ngokubanzi yokukhetha
1. Ngokweemfuno zokuqhuba kunye nokulawula imisebenzi yenkqubo, ngokufanelekileyo khetha umsebenzi kunye neentlobo zevalve ye-hydraulic, kwaye wenze i-circuit ye-hydraulic epheleleyo kunye ne-system schematic diagram kunye nepompo ye-hydraulic, i-actuator kunye nezixhobo ze-hydraulic.
2. Iimveliso ezisemgangathweni ezikhoyo zikhethwayo, kwaye iivalve ezikhethekileyo zokulawula i-hydraulic ziyilwe ngokwazo ngaphandle kokuba kuyimfuneko.
3. Ngokwenkqubo yokusebenza koxinzelelo kunye nokuhamba (ukuhamba komsebenzi) kwaye uqwalasele uhlobo lwevalve, ukufakwa kunye nendlela yokudibanisa, indlela yokusebenza, indawo yokusebenza, ubungakanani kunye nomgangatho, ubomi bokusebenza, uqoqosho, ukulungelelaniswa kunye nokugcinwa lula, ukubonelela kunye nemveliso. imbali njl zikhethwa kwiincwadana zoyilo ezifanelekileyo okanye iisampuli zemveliso.
Uhlobo olukhethiweyo lwevalve ye-hydraulic
Iimfuno zokusebenza zenkqubo ye-hydraulic zihluke, kwaye iimfuno zokusebenza kwevalve ye-hydraulic ekhethiweyo nazo zihluke, kwaye ezininzi iintsebenzo zichaphazelekayo yimpawu zesakhiwo.Umzekelo, kwinkqubo efuna isantya sokubuyisela umva ngokukhawuleza, ivalve ye-AC electromagnetic reversing valve ikhethwa ngokubanzi;ngokuchaseneyo, kwinkqubo efuna isantya esicothayo sokubuyisela umva, ivalve ye-DC electromagnetic reversing valve inokukhethwa;umzekelo, kwi-hydraulic system, i-spool reset kunye nokusebenza kwe-centering Ukuba iimfuno zingqongqo ngokukodwa, i-hydraulic centering structure ingakhethwa;ukuba i-valve yokukhangela i-hydraulically controlled check isetyenziswe, kwaye uxinzelelo lwangasemva lwe-oyile ye-reverse luphezulu, kodwa uxinzelelo lolawulo alukwazi ukunyuswa kakhulu, uhlobo lokuvuza lwangaphandle okanye uhlobo lomqhubi kufuneka lukhethwe.Ulwakhiwo: Ukuze i-valve yoxinzelelo ikhusele ukhuseleko lwenkqubo, kufuneka ibe nempendulo ebuthathaka, i-overshoot encinci yoxinzelelo, ukuphepha uxinzelelo lwempembelelo enkulu, kunye nokuthatha impembelelo eyenziwa xa i-valve yokubuyisela iguqulwa, ngoko ke. iyimfuneko ekukhetheni amacandelo anokufikelela kwiimfuno zokusebenza ezingentla.;Ukuba ivalve yokuqukuqela jikelele ayikwazi ukuhlangabezana neemfuno zokuchaneka kwentshukumo ye actuator ngenxa yotshintsho kuxinzelelo okanye ubushushu, ivalve elawula isantya enesixhobo sembuyekezo yoxinzelelo okanye isixhobo sembuyekezo yobushushu kufuneka ikhethwe.
Ukukhethwa koxinzelelo lweMimandla kunye nokuQuquza okuQiniweyo
(1) Ukukhethwa koxinzelelo oluqhelekileyo (uxinzelelo olulinganisiweyo)
Ivalve ye-hydraulic yenqanaba loxinzelelo oluhambelanayo inokukhethwa ngokuhambelana noxinzelelo olusebenzayo olugqitywe kuyilo lwenkqubo, kwaye uxinzelelo olusebenzayo lwenkqubo kufuneka lube ngaphantsi ngokufanelekileyo kunexabiso eliphantsi loxinzelelo olubonakaliswe kwimveliso.Iivalve ze-hydraulic zechungechunge loxinzelelo oluphezulu zisebenza ngokubanzi kuzo zonke iintlobo zoxinzelelo olusebenzayo ngaphantsi koxinzelelo olulinganisiweyo.Nangona kunjalo, ezinye izibonakaliso zobugcisa ezenzelwe amacandelo aphezulu oxinzelelo lwe-hydraulic phantsi kweemeko zoxinzelelo ezilinganisiweyo ziya kwahluka ngandlel' ithile phantsi koxinzelelo oluhlukeneyo lokusebenza, kwaye ezinye izalathisi ziya kuba ngcono.Ukuba uxinzelelo olusebenzayo lwenkqubo ye-hydraulic luphezulu kancinci kunexabiso loxinzelelo olulinganisiweyo oluboniswe yi-valve ye-hydraulic ngexesha elifutshane, ngokuqhelekileyo kuvunyelwe.Kodwa akuvumelekanga ukusebenza kweli lizwe ixesha elide, ngaphandle koko kuya kuchaphazela ubomi obuqhelekileyo bemveliso kunye nezinye izikhombisi zokusebenza.
(2) Ukukhethwa kokuhamba okulinganisiweyo
Umqukuqelo olinganisiweyo wevalve nganye yolawulo lwe-hydraulic kufuneka ngokubanzi ube kufutshane nokuhamba kwayo kokusebenza, olona ngqamaniso lunoqoqosho nolufanelekileyo.Kwakhona kunokwenzeka ukusebenzisa i-valve kwixesha elifutshane lokuhamba kwexesha elifutshane, kodwa ukuba i-valve isebenza ngokuhamba komsebenzi omkhulu kunomlinganiselo wokuhamba kwexesha elide, kulula ukubangela ukuba i-hydraulic clamping kunye namandla e-hydraulic kwaye ichaphazele kakubi. umgangatho wokusebenza kwevalve.
Ukuhamba kwesekethe nganye yeoli kwinkqubo ye-hydraulic ayikwazi ukufana, ngoko ke iiparameters zokuhamba kwevalve azikwazi ukukhethwa nje ngokuhambelana nokuphuma okuphezulu komthombo we-hydraulic, kodwa ukuhamba okunokwenzeka kwevalve nganye ngokusebenzisa inkqubo ye-hydraulic phantsi kwayo yonke into. Iimeko zoyilo kufuneka ziqwalaselwe.Ubuninzi bezinga lokuhamba, umzekelo, isantya sokuhamba kwesekhethi yeoli yechungechunge ilingana;isantya sokuhamba kwe-parallel oil circuit esebenza ngexesha elifanayo lilingana nenani lezinga lokuhamba kwesiphaluka ngasinye seoli;kwi-valve yokubuyisela i-different cylinder hydraulic cylinder, ukhetho lokuhamba kufuneka luthathele ingqalelo isenzo sokuguqula i-cylinder ye-hydraulic., Isantya sokuhamba esikhutshwe kwi-rodless cavity sikhulu kakhulu kunombhobho wentonga, kwaye ingaba mkhulu kuneyona nto iphezulu yokuphuma kwipompo ye-hydraulic;kwivalve yokulandelelana kunye ne-valve yokunciphisa uxinzelelo kwinkqubo, ukuhamba komsebenzi akufanele kube kuncinci kunomlinganiselo olinganisiweyo.Ngaphandle koko, ukungcangcazela okanye ezinye izinto ezingazinzanga ziyakwenzeka ngokulula;kwiivalve ze-throttle kunye ne-speed control valves, ingqwalasela kufuneka ihlawulwe kwinqanaba elincinci elizinzile.
