Abasebenzisi abaningi be-imishini yokumba ejikelezayouhlangabezane nenkinga yeibha kellyukushelela phansi ngesikhathi sokwakha. Eqinisweni, lokhu akuhlangene nomkhiqizi, imodeli, njll. Kuyiphutha elivamile. Ngemva kokusebenzisa i-rotary drilling rig isikhathi esithile, ngemva kokubuyisela isibambo sokusebenza endaweni engathathi hlangothi, ibha ye-kelly izoslayida yehle ibanga elithile. Lesi simo sivame ukubiza ngokuthiibha kellyeshelela phansi. Ngakho siyixazulula kanjani inkinga yokushibilika kwe-kelly bar?
1. Indlela yokuhlola
(1) Hlola i-valve ye-solenoid 2
Hlola ukuthi i-solenoid valve 2 ivalwe ngokuqinile yini: khipha amapayipi kawoyela amabili aholela ku-solenoid valve 2 kumotho, bese uvimbele izimbobo zikawoyela ezimbili ekugcineni kwenjini ngamapulaki amabili ngokulandelanayo, bese usebenzisa indlela yokuwina eyinhloko. Uma isebenza ngokujwayelekile, ibonisa iphutha Kusuka ku-valve ye-solenoid 2 ayivaliwe ngokuqinile; uma kuseyinto engavamile, kuyadingeka ukuhlola izingxenye zayo.
(2) Hlola ingidi ye-hydraulic
Hlola ukuthi ingabe kukhona inkinga nge-hydraulic lock: qala ulungise amasilinda amabili wokukhiya, uma kungasebenzi, bese ususa ilokhi ukuze uhlolwe ngokucophelela. Uma isizathu singatholakali, isikhiya esenziwe ngomumo singasetshenziselwa ukuhlolwa kokufakwa ukuze kutholwe imbangela yokwehluleka. Ngenxa yokuthi i-hydraulic lock ye-axiliary hoist ifana neye-hoist eyinhloko, ingidi ye-axiliary hoist nayo ingaboleka futhi ishintshwe ngayinye ngayinye ukuze kuhlonzwe ikhwalithi ye-hoist lock eyinhloko. Uma ingekho inkinga ngawo womabili amalokhi, qhubekela eshekeni elilandelayo.
(3) Hlola amafutha esignali yebhuleki
Hlola ijubane lokunikezwa kwamafutha esignali ye-brake kanye nekhefu: i-drilling rig yamanje, ukugeleza kwamafutha esignali kungalungiswa, okungukuthi, isikhathi lapho i-winch eyinhloko ikhulula i-brake ingalungiswa. Ngakho-ke, ezinhlotsheni ezimbili zemishini yokumba, ukugeleza kwamafutha esignali kungalungiswa nge-valve yayo yokulawula. Uma isimo sokusebenza somshini sisangavamile, kuyadingeka ukuhlola ukuthi ipayipi lamafutha lamafutha esignali ye-brake livinjelwe yini. Uma lezi zingxenye zokuhlola zivamile, ungaqhubeka kuphela ukuhlola
(4) Hlola ibhuleki:
Hlola ukuthi i-brake piston ihamba kahle yini emgqeni wokusebenza, futhi uyilungise noma uyishintshe ngokwembangela yokwehluleka.
Ibha ye-kelly ye-I-Rotary drilling rigigxilile esigubhuni sokuphakamisa esikhulu ngentambo yocingo, futhi ipayipi lokubhoboza lingaphakanyiswa noma lehliswe ngendlela efanayo lapho isigubhu noma intambo yocingo ikhululwa. Amandla e-reel avela kunjini yokuphakamisa eyinhloko eyehliswa kaningi. Ukuma kwayo kutholwa yibhuleki elifakwe ngqo kumshini wokuwashisa. Ngesikhathi sokuphakamisa noma ukwehlisaibha kelly, uma isibambo sokusebenza sibuyiselwa phakathi Uma iibha kellyayikwazi ukuma ngokushesha bese uslayida phansi ibanga elithile ngaphambi kokuma, kunezizathu ezintathu zalezi zizathu ezilandelayo:
1. I-braking lag;
2. Izingidi ezimbili ze-hydraulic ekuphumeni kokuphela kwemoto ziyahluleka, futhi injini ayikwazi ukuyeka ukujikeleza ngokushesha ngaphansi kwesenzo setorque yentambo yocingo;
Esivame ukungakunaki isizathu sesithathu. KonkeI-Rotary drilling rigube aibha kellyumsebenzi wokukhipha. Lo msebenzi uhlinzekwa i-valve ye-solenoid ukukhulula uwoyela wesignali ye-brake, bese i-valve ye-solenoid ixhunywe enjinini enkulu ngamapayipi amabili kawoyela. I-oil inlet kanye ne-outlet ye-hoist motor iqinisekisa ukuthi i-rotary drilling rig encane ingahlala ithintana nomhlabathi osebenzayo futhi ibe nokucindezela okuthile phakathi nenqubo yokumba. Kwezinye izimo zokusebenza, i-valve ye-solenoid inqamula amapayipi amabili kawoyela aholela endaweni yokungena kawoyela nokuphuma kukawoyela enjini. Uma ukunqanyulwa kungenasikhathi, iphutha elishiwo ngenhla lizokwenzeka.
