709-62-12101VALVE SSSY(B)
Kwindibano yevalvu yebulldozer, ivelufa yokwalatha licandelo elingundoqo elilawula intshukumo yesixhobo esisebenzayo (njengefotsholo yebulldozer, isixhobo sokukhulula umhlaba) kunye nendlela yokuhamba. Umsebenzi wayo ophambili kukutshintsha indawo ehambelanayo yesiseko sevalve kumzimba wevalve, utshintshe indlela yokuhamba kweoyile ye-hydraulic, kwaye ngaloo ndlela ufezekise "isenzo sangaphambili, isenzo sokubuyisela umva okanye ukumisa" kumacandelo aphumezayo (afana ne-hydraulic cylinder, hydraulic motor). Oku kulandelayo kunika inkcazo eneenkcukacha yesakhiwo, imigaqo engundoqo, iintlobo eziqhelekileyo, kunye nokusetyenziswa okuthe ngqo kwe-bulldozers: I-1, Ulwakhiwo olusisiseko lwe-valve ye-directional Amacandelo angundoqo e-valve ye-directional abandakanya iindawo ezintathu eziphambili: Umzimba weValve: Njengesiseko esisisigxina, uneendlela ezininzi ze-oyile kunye namachweba acutshungulwayo ngaphakathi, ngokuqhelekileyo aquka: I-oil inlet (P port): {Qhagamshela kwi-hydraulic hydraulic high} i-oyile;Izibuko lokuBuyisa (izibuko le-T): Qhagamshelana itanki yeoli kwaye ukhuphe i-oyile ephantsi{4}}i-oyile yoxinzelelo ibuyele kwitanki;Izibuko ze-oyile ezisebenzayo (Izibuko, izibuko le-B): Qhagamshela iinxalenye ze-actuator (ezifana namagumbi angenantonga kunye ne-rodless ye-hydraulic cylinders, okanye izibuko ezimbini zeoyile zeenjini zehydraulic) . igxalaba eliyilwe ngokuchanekileyo (okanye igroove) kumphezulu. Ukucocwa phakathi kwegxalaba kunye nomzimba wevalve kuncinci kakhulu (ngokuqhelekileyo kuluhlu lwe-micrometer), kwaye indawo ehambelanayo kunye ne-oil port ingatshintshwa yintshukumo yokulawula ukuvulwa kunye nokuvalwa kwe-oyile passage.Drive device: Umthombo wamandla oqhuba ukuhamba kwe-valve core. Ngenxa yesidingo sokuthwala imithwalo emikhulu, i-hydraulic drive idla ngokusetyenziswa kwii-bulldozers (ngokulawula i-oyile yoxinzelelo kwi-oyile yesiphaluka ukutyhala i-valve core), kunye nezinye ii-bulldozers ezincinci zinokuncedisa ukuqhuba ngesandla; Ukusetwa kwakhona kwesiseko se-valve ngokuqhelekileyo kuxhomekeke kwintwasahlobo (ukuqinisekisa ukuba ibuyela kwindawo engathathi hlangothi xa kungekho mandla okuqhuba).
amatyala aphumeleleyo
Khetha isicwangciso esikufaneleyo.
Umkhombandlela wokuhamba kwe-oyile kwiindawo ezahlukeneyo (uthatha ibulldozer ephakamisa njengomzekelo)
Indawo ephakathi (undoqo wevalvu uphakathi):
Igxalaba eliphumayo le-valve core litywina zonke izibuko ze-P (i-oil inlet), izibuko (ezidityaniswe kwi-cylinder ye-hydraulic ye-bulldozer ngaphandle kwegumbi lentonga), kunye namazibuko e-B (adityaniswe negumbi lezintonga), kunye ne-T port kuphela (i-oil return) evulwe ngokwahlukileyo. Ngeli xesha, ukukhutshwa kweoli ngepompo ye-hydraulic ayikwazi ukungena kwi-cylinder ye-hydraulic kwaye ibuyiselwe ngokuthe ngqo kwitanki yeoli ngokusebenzisa i-valve yokunceda, ngelixa i-bulldozer ihlala imile (ingayikhuli okanye iwa).
Indawo yasekhohlo (undoqo wevalvu ushukuma ekhohlo):
Emva kokuba i-valve core ihamba, i-port ye-P iqhagamshelwe kwi-port A, kunye ne-B port idityaniswe kwi-T port.
Ioyile yoxinzelelo oluphezulu ingena kwigumbi elingenantonga le-cylinder ye-hydraulic ukusuka kwi-port P ukuya kwi-port A (igumbi elingenazintambo linendawo enkulu kunye ne-high thrust), iqhube i-piston ukuba yandise kwaye iqhube i-bulldozer ukuba iphakame;
Ioyile ekwigumbi lentonga ye-hydraulic cylinder ibuyela kwitanki yeoli ukusuka kwi-port B ukuya kwi-port T, ukugqiba umjikelo.
Indawo ekunene (undoqo wevalvu ushukuma ukuya ekunene):
Emva kokuba i-valve core ihamba, i-port ye-P idityaniswe kwi-port B, kwaye i-port A iqhagamshelwe kwi-T port.
Ioli yoxinzelelo oluphezulu ingena kwigumbi lentonga ye-hydraulic cylinder ukusuka kwi-port P ukuya kwi-port B, iqhube i-piston ukuba ihoxise kwaye iqhube i-bulldozer ukuba yehle;
Ioyile ekwigumbi elingenantonga le-hydraulic cylinder iqukuqela ibuyela kwitanki yeoli ukusuka kwizibuko A ukuya kwizibuko T, igqibezela ukujikeleza okubuyela umva.
Iinkcukacha zoyilo eziphambili zevalve yolwalathiso kwi-bulldozer
Ukutywina kunye noThintelo lokuvuza:
Ucoceko phakathi kwesiseko sevalve kunye nomzimba wevalve kufuneka ilawulwe ngokungqongqo (ngokuqhelekileyo i-0.005-}0.01mm) ukuqinisekisa ukunyakaza okuguquguqukayo kwesiseko sevalve kunye nokunciphisa ukuvuza kwangaphakathi (ukuba ucoceko lukhulu kakhulu, i-oyile yoxinzelelo oluphezulu iya kuvuza ngokuthe ngqo kwi-P port ukuya kwi-T port, ebangela ukuba i-actuator ibe buthathaka). Inxalenye yomgangatho wevalve iya kuba yi-chrome efakwe kwiplatifomu ukuze kuphuculwe ukumelana nokunxiba kunye nokutywinwa.
Uzinzo kuhambo:
Isantya sokuhamba sondoqo wevalve kufuneka silawuleke (esiyilwe ngemingxunya ye-throttle okanye i-buffer slots) ukuphepha impembelelo ebangelwa ukuguqulwa kwe-oyile ngequbuliso (efana "nokuxhuzula" ngexesha lokuphakanyiswa kwefosholo ye-bulldozer), kunye nokukhusela i-cylinder ye-hydraulic kunye ne-structural components.
Uhlengahlengiso lokulayisha:
Ngethuba lokusebenza kwe-bulldozer, kukho ukuguquguquka okuphawulekayo komthwalo (njengokuhlangabezana neebhloko zomhlaba okhuni), kwaye i-valve yesikhokelo kufuneka idibaniswe ne-valve yokunceda: xa umthwalo kwi-actuator udlula ixabiso elibekiweyo, i-valve yokunceda iya kukhulula uxinzelelo ukuze ugweme umonakalo kwi-valve yesikhokelo ngenxa yoxinzelelo oluphezulu.
Iimeko ezithile zokusetyenziswa kwiibulldozers
Isenzo se-Bulldozer: I-cylinder ye-hydraulic ye-bulldozer ilawulwa ukuba yandise kwaye ihlehlise ngevalve ye-directional, iphumelele "ukuphakamisa, ukwehlisa, kunye nokumisa". Ngevalve yendlela ye-cylinder ejikelezayo, i-bulldozer inokulawulwa ukuba ijikeleze ngakwesobunxele okanye ngasekunene (ukulungelelanisa i-angle bulldozer).
Isenzo sesixhobo sokukhulula: Lawula ukwandiswa kunye nokucutheka kwesilinda esiqhutywa ngamanzi esixhobo sokukhulula umhlaba ukuze siphumeze "ukungena emhlabeni, ukuphakamisa", nokwaphula umhlaba oqinileyo okanye iileya zamatye.
Utshintsho lwendlela yokuhamba: Ezinye iibulldozers' walk hydraulic motors (iingoma zokuqhuba) zikwalawula icala le-oyile ngeevalvu eziya ngakulo, ukufikelela "phambili nangasemva" ukutshintshela.
Isishwankathelo, i-valve ye-directional itshintsha indlela yokuhamba kweoli ngokulawula ngokuchanekileyo indawo engundoqo yevalve, eyona nto ingundoqo ye-bulldozers ukufezekisa "ulwalathiso lwesenzo esilawulwayo". Ukusebenza kwayo kuchaphazela ngokuthe ngqo isantya sempendulo yokusebenza, uzinzo lokusebenza, kunye nobomi besixhobo.
