Hloov Cov Throttling Valve Cheebtsam rau Drilling Rigs:
Hloov lub Valve Disc thiab Valve Rooj: Tshem lub siab nyob rau hauv lub valve kab noj hniav, tshem tawm lub valve cover bolts, thiab tshem tawm lub valve disc nrog rau sab sauv ntawm lub valve cover los ua ke. Tshem cov txiv ntoo puag ncig, hloov tus pin, hex screws, thiab lub kaus mom rau pem hauv ntej thiab nram qab; lub cylindrical valve disc tuaj yeem hloov tau, thiab lub rooj zaum valve hloov ib txhij. Ntxuav lub valve kab noj hniav, them nyiaj tshwj xeeb rau cov sealing nto. Thaum txhim kho lub valve disc tshiab thiab lub rooj zaum valve, qhov kev tshem tawm ntawm lub valve disc thiab tus thawj coj ntawm lub valve yuav tsum tau ntim nrog cov roj sealing; Tsis tas li ntawd, sab hauv ntawm lub hau yuav tsum tau ntim nrog calcium -raws li lubricating roj los lubricate cov bearings.
Hloov daim di ncauj Foob (Packing): Ua ntej, txo lub siab nyob rau hauv lub valve kab noj hniav; Tom qab ntawd, disassemble lub cover tiv thaiv, round txiv ntseej, handwheel, bearing caj pas, bearings, thiab packing gland ua ntej hloov lub di ncauj seals.
Hloov Cov Bearings: Disassemble lub hau tiv thaiv, round txiv ntseej, handwheel, thiab bearing caj pas; cov kabmob tuaj yeem hloov tau. Yog hais tias qhov qis bearing yuav tsum tau hloov, lub valve qia txiv ntoo yuav tsum tau muab tshem tawm. Cov kabmob clearance yog kho los ntawm cov kabmob npog; Thaum qhov kev hloov kho tiav lawm, tig lub log ntawm tes yuav tsum ua rau kev txav mus los tsis muaj kev khi lossis jamming.
