Ukuhlaziywa kokusetshenziswa komshini wokusika we-hydraulic?
Isici somshini wokusika we-hydraulic ukuthi lapho ikhanda lokusika lisetshenziswa ezintweni ezicutshungulwayo ngokusebenzisa isikhunta sommese, ingcindezi ku-cylinder esebenzayo ayifinyeleli ukucindezela okulinganiselwe, ingcindezi izokhula ngesikhathi sokuxhumana (sike sibe yi- into esebenzayo), kuze kube yilapho i-valve yokuhlehla kagesi ithola isignali, i-valve ehlehlayo iyashintsha, futhi ikhanda lokusika liqala ukusetha kabusha;
Ngalesi sikhathi, ingcindezi ku-cylinder ingase ingafinyeleli inani elilinganiselwe lokucindezela elilinganiselwe ngenxa yokulinganiselwa kwesikhathi samafutha okucindezela ukungena ku-cylinder; okungukuthi, ingcindezi yesistimu ayifinyeleli inani lokuklama, futhi ukubhoboza kuqediwe.
Umshini wokusika we-Hydraulic
Ukudluliswa kwe-Hydraulic komshini wokusika, endaweni evamile. Emshinini wokusika we-hydraulic, inani elikhulu lalokho okusetshenzisiwe yi-tonnage ku-8-20 amathani omshini wokusika izingalo ezinyakazayo. Uhlobo lwepuleti eliyisicaba kanye nemishini yokusika i-gantry isetshenziswa kakhulu kubakhiqizi abakhulu kakhulu, bafaneleka kakhulu isikhumba, izinto zokwenziwa ezingezona ezensimbi.
I-valve yokuhlehlisa umoya yesiphakeli somshini wokusika inephutha
Amaphutha e-valve ehlehlayo yomshini wokusika okuzenzakalelayo yilezi: i-valve ayikwazi ukushintsha noma ukuhamba kancane, ukuvuza kwegesi, futhi i-valve yomshayeli we-electromagnetic inephutha.
(1) i-valve ehlehlayo ayikwazi ukushintshwa noma isenzo sihamba kancane, ngokuvamile esibangelwa ukugcotshwa okungalungile, ukubhajwa kwentwasahlobo noma okonakele, uwoyela noma ukungcola okubhajwe ingxenye eshelelayo nezinye izizathu. Mayelana nalokhu, qala uhlole ukuthi idivayisi yenkungu yamafutha isebenza kahle yini; kungakhathaliseki ukuthi i-viscosity yamafutha okugcoba ifanelekile. Uma kunesidingo, shintsha uwoyela wokugcoba, hlanza ingxenye eshelelayo yevalvu ehlehlayo, noma shintsha i-spring nevalve yokuhlehla.
(2) I-valve yokushintsha yomshini wokusika ozenzakalelayo isikhathi eside kulula ukubonakala i-valve core yokuvala indandatho yokuguga, isiqu se-valve kanye nomonakalo wesihlalo, okuholela ekuvuzeni kwegesi ku-valve, isenzo esihamba kancane se-valve noma ukungashintshi okujwayelekile kokuqondisa kanye namanye amaphutha. . Ngalesi sikhathi, indandatho yokuvala, isiqu se-valve kanye nesihlalo se-valve kufanele kushintshwe, noma i-valve yokuhlehla kufanele ishintshwe.
(3) Uma izimbobo zokungena nokukhipha i-valve yomshayeli we-electromagnetic pilot zivalwe ngodaka nezinye izibi, ukuvala akuqinile, umgogodla onyakazayo unamathele, iphutha lesifunda, lingaholela ku-valve ehlehlayo ayikwazi ukushintshwa ngokujwayelekile. Ezimweni ezi-3 zokuqala, i-sludge yamafutha kanye nokungcola ku-valve yokushayela kanye nensimbi ehambayo kufanele kuhlanzwe. Futhi iphutha lesekethe livame ukuhlukaniswa ngephutha lesekhethi yokulawula kanye nephutha lekhoyili kagesi izigaba ezimbili. Ngaphambi kokuhlola iphutha lesifunda, kufanele siphendule inkinobho ye-manuwali ye-valve yokuhlehlisa izikhathi eziningana ukuze sibone ukuthi ingabe i-valve yokuhlehla ingashintsha ngokujwayelekile ngaphansi kwengcindezi elinganiselwe. Uma isiqondiso esivamile singashintshwa, isifunda sinephutha. Ngesikhathi sokuhlolwa, ithuluzi lingasetshenziswa ukukala i-voltage yekhoyili kazibuthe ukuze kubonakale ukuthi i-voltage elinganiselwe ifinyelelwe yini. Uma i-voltage iphansi kakhulu, qhubeka uhlole ukunikezwa kwamandla kumjikelezo wokulawula kanye nesekethe yokushintshwa kwe-stroke ehambisanayo. Uma i-valve yokuhlehla ingakwazi ukushintsha ngokujwayelekile ku-voltage elinganiselwe, hlola ukuthi isixhumi (ipulaki) se-solenoid sikhululekile noma asixhumene. Indlela yokukhipha ipulaki nokukala ukubaluleka kokumelana kwekhoyili. Uma inani lokumelana likhulu kakhulu noma lilincane kakhulu, ikhoyili kagesi ilimele futhi kufanele ishintshwe.
