ERT(Kunyange Rubber Kukora):
Zvinonzwisisika kushandura chimiro che stator imba, iyo stator elastomer layer yeUniform Ukobvu downhole mota yakatetepa uye kunyange. Hunhu hweiyo downhole mota hurefu hupfupi, simba repamusoro, kudonha kwakanyanya, kuderera kutenderera kumhanya, kutonhora kwakanyanya, kunyangwe kuwedzera kwemafuta, kushandiswa zvakanyanya, kuwedzeredza chimiro uye kureruka. Kunyanya, hunhu hunogona kurebesa hupenyu hwemota yekudzika uye kuvandudza kudhirowa mutsime rekupedzisira-rakadzika, rinotungamira zvakanaka uye tembiricha yakakwira zvakanaka.
Resistance High-temperature Uye Oiri Yakavakirwa Madhaka:
Iyo downhole mota inokodzera yakakwirira-tembiricha, yakakwira mafuta base mud system. Mumamiriro ezvinhu asingasviki 180 ° C uye mafuta akakwirira, yakanyatsogadzirwa stator elastomer ine mazinga ekuchengetedza akakwirira esimba rakasimba resimba, kubvarura simba uye zvimwe zvinhu. Iyo inodzivirira oiri elastomer ine hukuru hwekuvhiringidza ine zvirinani kushandisa mhedzisiro mune yakakwirira-tembiricha, yakakwira mafuta base madhaka.
Corrosion-resistance:
Mushure mekupfapfaidza ngura kuti igadzire kupfekedzwa kwakakosha, rotor iri nani kukora, kukukurwa uye kusagadzika. Uye downhole mota inokodzera kwenguva yakareba mumvura inoparadza.
Air Drilling:
Kuchera mhepo kunogona kuchengetedza dura zvakanaka, kunatsiridza mwero wekupinda, kupfupisa zvakanyanya nguva yekuchera, kutora chenjedzo pakurasikirwa nedhaka uye kudonha kwechibhorani, iko zvino kuri kushandiswa zvakanyanya zvishoma nezvishoma. Mhepo yekuchera pasi mota inofambiswa negasi, furo uye zvimwe zvinwiwa zvinomisikika, zvinopa simba rekudzika uye kutyaira zvishoma kuti ipinde mudombo. Mhepo kudhiraivha downhole mota ine yepamusoro tekinoroji zvinodiwa zvechimiro chegungano, mutsara dhizaini yemota stator uye mashandiro ekuita.
