Kubyerekeranye na hydraulic yamena, nkuko twese tubizi, ingaruka piston ningirakamaro murutonde rwibice byingenzi. Kubijyanye no kunanirwa kwa piston, akenshi usanga ari byinshi, kandi muri rusange bitera kunanirwa gukomeye, kandi ubwoko bwatsinzwe bugaragara bitagira iherezo. Kubera iyo mpamvu, HMB yavuze muri make impamvu nyinshi zitera piston.
1.Ibishushanyo hejuru yumurimo, Piston strain crack
Impamvu:
● Ubuso buke
Koresha igeragezwa rikomeye kugirango upime ubukana bwibanze (35 ≥ 45 nigiciro cyemewe cyemewe) ③Niba kiri munsi ya dogere 35 cyangwa se hejuru ya dogere 20 gusa, piston nini, cyane cyane yamenagura hydraulic ifite ingufu zingirakamaro cyane, cyane cyane kumeneka hejuru ④ Nyuma yo kugaragara, kwihanganira kuruhande rumwe bizaguka mumigozi mirongo, bityo bisenya icyuho gisanzwe kiri hagati ya piston na silinderi, bitera umurego ukomeye.
Imyanda ivanze n'amavuta ya hydraulic
● Ikinyuranyo kiri hagati yimyitozo yo kuyobora inkoni (ibihuru byo hejuru no hepfo) ni binini cyane, kandi amaboko yo kuyobora birananirana.
Iyo inkoni y'imyitozo ikora, umurongo uhengamye. Iyo piston ikubise inkoni ya drill, yakira imbaraga zifatika zifatika, zishobora kubora imbaraga za axial nimbaraga za radiyo, kandi imbaraga za radiyo zishobora gusunika piston kuruhande rumwe, icyuho cyambere kirazimira, firime yamavuta irasenyuka, yumye ubushyamirane bukorwa hagati ya silinderi nubuso bwa piston, kandi hejuru ya piston yashushanyije nkibisubizo.
Kumenagura piston
Impamvu:
Ikibazo
Carburized low-alloy piston piston nintandaro yimbere yingaruka zirangira ihungabana no gucika.
Itandukaniro ryubukomezi hagati yigitero cya piston nigice gikomeye cyinkoni ya drill igomba kuba ikwiye
②Ikibazo cyo kuvura ubushyuhe
Mugihe cyo guhimba cyangwa kuvura ubushyuhe, ibikoresho bya piston bitanga ibice, byagura ibice kugeza byacitse bitewe nigikorwa cyo guhinduranya.
3.Piston ifite umwobo wimbitse, kandi umubiri wa silinderi ufite ingingo-ku-ngingo ihuriweho na longitudinal;
Impamvu：
Kwinjiza umwanda, bigatuma piston itakaza uburinganire imbere ninyuma, hamwe nigitekerezo cyo kugoreka umutwe, bigatera umurego
Av Cavitation, cavitation muri rusange iboneka muri silinderi, ntabwo iri kuri piston. Cavitation izatera umwobo wimbitse, kandi ibikoresho birenze muri byo bizangirika mu ngaruka zihuse z’amavuta ya hydraulic, kandi silinderi yose izayungurura.
Ibinogo byangiza, nkuko bigaragara ku ishusho ntabwo ari ibyobo. Ibyobo byangirika mubisanzwe biterwa nibikoresho bya piston (urugero, ababikora bamwe bakoresha 42CRMO cyangwa bagakoresha gusa 40CR nibindi bikoresho kubera igitutu cyamasoko) cyangwa mugihe babibitse, ntibitaye kubisunika piston muri silinderi. Mu minsi yimvura, Ruswa iterwa igihe kirekire, kandi ingese yumuhondo ihinduka ingese yumukara amaherezo ikaba urwobo. Mubisanzwe, ibi bintu birasanzwe kumeneka mato na micro bitangira kumeneka amavuta mbere yigihe cyo kubungabunga.
NIBA hari icyo ufite, nyamuneka twandikire! Reka dukemure ikibazo hamwe, ngwino !!
