Unokukhetha njani izihluzi zoxinzelelo lwehydraulic?
Umsebenzisi kufuneka aqale aqonde imeko yenkqubo yabo ye-hydraulic, kwaye emva koko ukhethe isihluzo. Injongo yokukhetha: ubomi benkonzo ende, kulula ukuyisebenzisa, kunye nesiphumo esinelisayo sokucoca.
Imiba enempembelelo kubomi benkonzo yokucocaInto yokucoca efakwe ngaphakathi kwisihluzo solwelo lolwelo lubizwa ngokuba sisihluzo, kwaye imathiriyeli yayo ephambili sisihluzo sesikrini. Isihluzi silukiweyo ikakhulu umnatha, isihluzo sephepha, isihluzo sefayibha yeglasi, isihluzo sefayibha yekhemikhali kunye nesihluzo sefayibha yesinyithi. Imithombo yeendaba yokucoca eyenziwe ngocingo kunye neefayili ezahlukeneyo zibuthathaka kakhulu kwi-texture, nangona inkqubo yokuvelisa ezi zixhobo ziphuculwe (ezifana ne: i-lining, impregnating resin), kodwa kusekho imida kwiimeko zokusebenza. Izinto eziphambili ezichaphazela ubomi bokucoca zichazwe ngolu hlobo lulandelayo.
1. Uxinzelelo lwehla kuzo zombini iziphelo zesihluziXa ioli idlula kwindawo yokucoca, ukuhla koxinzelelo oluthile kuya kuveliswa kuzo zombini iziphelo, kwaye ixabiso elithile lokunciphisa uxinzelelo lixhomekeke kwisakhiwo kunye nommandla wokuhamba kwendawo yokucoca. Xa into yokucoca isamkela ukungcola kwioyile, oku kungcola kuya kuhlala phezu komhlaba okanye ngaphakathi kwendawo yokucoca, ukukhusela okanye ukuvala ezinye ngemingxuma okanye iziteshi, ukwenzela ukuba indawo yokuhamba esebenzayo incitshiswe, ukwenzela ukuba ukuhla koxinzelelo kwi-filter element kwandiswe. Njengoko ukungcola okuvalwe yinto yokucoca kuqhubeka nokunyuka, uxinzelelo lwehla ngaphambi nangemva kokuba into yokucoca nayo iyanda. La masuntswana acunyuziweyo aya kucudisa kwimingxuma ye-medium kwaye aphinde angene kwinkqubo; Ukuhla koxinzelelo kuya kwandisa ubungakanani bomngxuma wokuqala, ukutshintsha ukusebenza kwento yokucoca kunye nokunciphisa ukusebenza kakuhle. Ukuba ukuhla koxinzelelo kukhulu kakhulu, kudlula amandla okwakhiwa kwecebo lokucoca, i-elementi yokucoca iya kucandwa kwaye idilike, ukuze umsebenzi wokucoca ulahleke. Ukuze wenze into yokucoca ibe namandla okwaneleyo ngaphakathi koluhlu loxinzelelo olusebenzayo lwenkqubo, uxinzelelo oluncinci olunokubangela ukuba into yokucoca icwecwe idla ngokusekwa njenge-1.5 amaxesha oxinzelelo olusebenzayo lwenkqubo. Oku kunjalo, xa ioli kufuneka inyanzeliswe ngoluhlu lokucoca ngaphandle kwevalve yokudlula. Olu yilo luhlala luvela kwizihluzi zemibhobho yoxinzelelo oluphezulu, kwaye amandla esixhobo sokucoca kufuneka aqiniswe kwi-skeleton yangaphakathi kunye ne-lining network (seeiso 2941, iso 16889, iso 3968).
2. Ukuhambelana kwezinto zokucoca kunye ne-oyileIfayile yokucoca iqulethe zombini izinto zokucoca isinyithi kunye nezixhobo zokucoca ezingezizo zetsimbi, ezona zininzi, kwaye zonke zinengxaki yokuba ziyakwazi ukuhambelana neoli kwinkqubo. Ezi ziquka ukuhambelana kweenguqu zeekhemikhali kunye neenguqu kwimiphumo ye-thermal. Ngokukodwa kwiimeko eziphezulu zokushisa akunakuchaphazeleka kubaluleke kakhulu. Ke ngoko, izinto ezahlukeneyo zokucoca kufuneka zivavanyelwe ukuhambelana kweoyile kumaqondo obushushu aphezulu (bona ISO 2943).
3.Impembelelo yobushushu obuphantsi bomsebenziInkqubo esebenza kumaqondo obushushu aphantsi nayo inefuthe elibi kwisihluzi. Kuba kumaqondo obushushu aphantsi, ezinye izinto ezingezizo ezentsimbi kwindawo yokucoca ziya kuba buthathaka ngakumbi; Kwaye kwiqondo lokushisa eliphantsi, ukunyuka kwe-oil viscosity kuya kubangela ukunyuka koxinzelelo, okulula ukubangela ukuqhekeka kwezinto eziphakathi. Ukuze uvavanye imeko yokusebenza kwesihluzi kwiqondo lokushisa eliphantsi, uvavanyo "lokuqala olubandayo" lwenkqubo kufuneka luqhutywe kwiqondo lokushisa eliphantsi lokugqibela lenkqubo. I-MIL-F-8815 inenkqubo yovavanyo olukhethekileyo. I-China Aviation Standard HB 6779-93 nayo inamalungiselelo.
4. Ukuhamba kweoyile ngamaxesha athileUkuqukuqela kweoyile kwinkqubo kudla ngokungazinzanga. Xa izinga lokuqukuqela litshintsha, liya kubangela ukugoba kobume becebo lokucoca. Kwimeko yokuhamba kwexesha, ngenxa yokuguqulwa okuphindaphindiweyo kwesixhobo sokucoca okuphakathi, kuya kubangela umonakalo wokukhathala kwezinto kwaye zenze iintanda zokukhathala. Ke ngoko, icebo lokucoca kuyilo lokuqinisekisa ukuba into yokucoca inokumelana nokudinwa okwaneleyo, ekukhetheni izixhobo zokucoca kufuneka ivavanywe (jonga i-ISO 3724).
