Yadda za a Magance Lalacewar Haɗawa a cikin Tricone Bit?

A matsayin ginshiƙi na hakowa mai da iskar gas da kayan aikin injiniya marasa ma'ana, ɗaukar nauyi shine "zuciya" natricone rawar jiki. Duk da haka, sau da yawa yana kasawa da wuri saboda matsananciyar yanayi mai zurfi, ya zama maɓalli mai mahimmanci wanda ke hana haɓaka hakowa.

Akwai manyan dalilai guda uku na lalacewa: 

Na farko, babban tasiri lodi da madaidaicin damuwa downhole. Radial runout da axial extrusion namazugia lokacin hakowa zai iya haifar da gajiyar gajiyar hanyar tseren da ke ɗauke da ita; 

Na biyu, mamayewar ruwa mai hakowa da yankewa. Hatimin al'ada ba zai iya ware ƙazanta yadda ya kamata ba, wanda zai haifar da lalacewa ta jiki; na uku, gazawar man shafawa. A cikin yanayin zafi mai zafi da matsananciyar matsa lamba, man shafawa yana da sauƙin diluted ko carbonized, rasa tasirin kariya.

Don magance waɗannan abubuwan zafi, Drillmore ya haɓaka manyan fasahohin da aka yi niyya guda uku don haɓaka ingantaccen haɓaka. 

Na farko, mun dauki a carburizing ƙarfafa tsari ga high-carbon chromium hali karfe, wanda ke ƙara ƙarfin ƙarfin daɗaɗɗa zuwa sama da HRC62 yayin da yake riƙe da ƙarfi na ainihin, samun ci gaba biyu a cikin juriya mai tasiri da juriya. 

Na biyu, mun kirkiro a Multi-tashar labyrinth hatimi + high-matsi lubrication hadedde tsarin, wanda yadda ya kamata ya ware hakowa ruwa mamayewa da kuma ci gaba da kari high-zazzabi mai mai maiko don kauce wa lubrication gazawar. 

Na uku, mun inganta tsarin abin nadi mai siffar zobe don rarraba nauyin a ko'ina a duk hanyar tseren kuma rage yawan damuwa na gida.
