Mayelana ne-hydraulic breaker, njengoba sazi sonke, i-piston yomthelela ibaluleke kakhulu ohlwini lwezingxenye eziyinhloko.Ngokuqondene nokwehluleka kwe-piston, ngokuvamile kuvame kakhulu, futhi ngokuvamile kubangela ukwehluleka okukhulu, futhi izinhlobo zokwehluleka zivela ngokungapheli.Ngakho-ke, i-HMB ifinyeze izimbangela eziningana zokuhluleka kwepiston.
1.Ukuklwebheka endaweni yokusebenza, ukuqhekeka kwe-Piston
Isizathu:
● ubulukhuni bobuso obuphansi
Sebenzisa isihloli sokuqina ukuze ulinganise ubulukhuni bomgogodla (35 ≥ 45 inani elamukelekayo lesikhawu sobulukhuni) ③Uma lingaphansi kwamadigri angu-35 noma ngisho nangaphezu kwama-degree angu-20, ama-piston amakhulu, ikakhulukazi ama-hydraulic breaker anamandla amakhulu uma kuqhathaniswa, ayakhona. ikakhulukazi ethambekele ekuqhekekeni komhlaba ④ Ngemva kokuvela kwemifantu, ukubekezelelana kolunye uhlangothi kuzokhula kumashumi ezintambo, ngaleyo ndlela kucekele phansi igebe elivamile phakathi kwepiston nesilinda, okubangela ubunzima obukhulu.
● Ukungcola okuxutshwe kuwoyela we-hydraulic
● Igebe phakathi komkhono we-drill rod (izihlahla ezingenhla nezingaphansi) likhulu kakhulu, futhi umkhono womhlahlandlela uyehluleka.
Lapho i-drill rod isebenza, i-axis iyashintsha.Lapho i-piston ishaya induku yokubhoboza, ithola amandla okusabela athambekele, angabolisa amandla e-axial namandla e-radial, futhi amandla e-radial angakwazi ukusunduza i-piston ohlangothini olulodwa, igebe lokuqala liyanyamalala, ifilimu kawoyela iyabhujiswa, yomile. kwakheka ukungqubuzana phakathi kwesilinda nendawo yepiston, futhi ingaphezulu lepiston liyaklwejwa ngenxa yalokho.
2.ukuphuka kwepiston
isizathu:
①Inkinga yezinto
I-carburized low-alloy steel piston iyimbangela yangaphakathi yokuphela komthelela ukudangala kobuso nokuqhekeka.
Umehluko wobulukhuni phakathi kwengxenye eshayayo yepiston nobulukhuni bengxenye yenduku yokubhoboza kufanele ufane
②Inkinga yokwelashwa kokushisa
Ngesikhathi sokufakelwa noma ukwelashwa kokushisa, impahla ye-piston ikhiqiza imifantu, eyandisa imifantu kuze kube yilapho iphukile ngaphansi kwesenzo sokushintshana kokucindezeleka.
3.I-piston inomgodi ojulile, futhi umzimba we-cylinder une-point-to-point symmetrical longitudinal strain;
Isizathu:
①Ukufaka ukungcola, okubangela ukuba ipiston ilahlekelwe ibhalansi ngaphambili nangemuva, ngomqondo wokutshekisa ikhanda, okubangela ubunzima
② I-Cavitation, i-cavitation ngokuvamile ivela ku-cylinder, hhayi ku-piston.I-Cavitation izobangela umgodi omnyama ojulile, futhi impahla eyengeziwe kuyo izochithwa emthelela osheshayo wamafutha we-hydraulic, futhi yonke i-cylinder izohlukunyezwa.
③Imigodi yokugqwala, njengoba kuboniswe esithombeni ayiyona imigodi yokugqwala.Imigodi yokugqwala ngokuvamile ibangelwa impahla ye-piston (isibonelo, abanye abakhiqizi basebenzisa i-42CRMO noma bamane basebenzise i-40CR nezinye izinto ngenxa yengcindezi yemakethe) noma lapho begcina, abazange banake ukuphusha ipiston kusilinda.Ezinsukwini zemvula, i-Corrosion ibangelwa isikhathi eside, futhi ukugqwala okuphuzi kuphenduka ukugqwala okumnyama futhi ekugcineni kube umgodi.Ngokuvamile, lesi simo sivamile kuma-breaker amancane namancane aqala ukuvuza uwoyela ngaphambi kwesikhathi sokunakekela.
UMA unokuthile, sicela ukhululeke ukuxhumana nathi!Asixazulule inkinga ndawonye, woza!!
