Cov neeg kho tshuab qhov chaw ntawm hydraulic hoses yog qhov tsim nyog rau kev sib txuas ntawm circuits, twj, li qub, lim, hoses, hlau hoses, thiab lwm yam. Qhov ntau yam ntawm hoses yog complex, cov qauv muaj ntau haiv neeg, thiab tej yam kev mob ntawm kev siv yog txawv. Qhov ntev ntawm lub neej hose nyob ntawm qhov tsis yog tsuas yog nyob ntawm qhov zoo, tab sis kuj yog siv thiab tu. Yog li ntawd, txawm tias cov khoom lag luam zoo, yog tias nws tsis siv thiab tswj kom raug, nws yuav cuam tshuam rau nws qhov zoo thiab lub neej.
Nyob rau hauv qhov project pressurized drilling, yog hais tias lub high-pressure hose siv muaj roj surge thiab to, cov hauv qab no yuav siv tau rau kev kho mob thaum muaj xwm ceev.
Ib tug yog txoj cai restructuring.
Vim muaj qhov sib txawv ntawm cov yeeb nkab sib txuas ntawm cov roj hmab hoses nyob rau hauv hydraulic systems, high-pressure los yog ultra-high-pressure rupture hoses yuav tsum tsis txhob sib koom, bundled los yog pob txha-bonded. Yog li ntawd, ib txoj kev kho dua tshiab tuaj yeem raug saws: sawing tawm ntawm cov yeeb nkab sib txuas ntawm lub ruptured hose; nrhiav lwm qhov hose nrog lub peev xwm zoo sib xws thiab qhov ntev mus rau qhov ruptured hose, sawing tawm nws cov yeeb nkab sib txuas; welding lub kaum sab xis ntawm lub ruptured hose sib koom ntawm lub hloov hose ntawm cov yeeb nkab; ntxuav lub welded hose thiab nws yog npaj siv.
Qhov thib ob yog txoj kev teeb tsa pob txha.
Thaum lub rupture ntawm cov roj hmab hose yog loj los yog yuav tawg vim yog sab nraud quab yuam (shrapnel tawg, extrusion rupture) los yog system overload, cov pob txha grafting txoj kev yuav siv tau: so lub ruptured ib feem ntawm lub hose huv si, txiav tawm. ruptured ib feem; Ntxig rau hauv lub hose txiav, thiab clamp lub hose thiab cov pob txha nrog ib tug self-made steel phaj clip (thaum muaj xwm ceev, siv No. 8 hlau hlau es tsis txhob ntawm tus kheej-ua steel phaj clip); ntxuav lub hose txuas thiab siv nws.
Qhov thib peb yog txoj kev khi.
Cov txheej txheem bundling yog tsim rau kev kho thaum muaj xwm ceev ntawm ruptured roj hmab hoses nrog siab tshaj 16MPa. Txoj kev tshwj xeeb yog siv ib qho ntawm cov roj hmab uas tau hais los saum toj no feem ntau siv hauv kev tsim kho tshuab ntawm qhov tawg ntawm lub hose, thiab cov roj hmab-resistant daim tawv nqaij uas nws qhov dav yog 2 mus rau 3 npaug ntawm qhov ntev ntawm qhov ruptured yog qhwv ib ncig ntawm 2. mus rau 3 txheej ntawm rubberized ib feem (txheej txheej txhua txheej), thiab siv roj-resistant roj hmab daim tawv qhwv nrog 12-gauge hlau
Qhov thib plaub yog txoj kev siv hluav taws xob hluav taws xob.
Hauv hydraulic system ntawm kev tsim kho tshuab, qee cov roj hluav taws xob ua lub luag haujlwm hauv kev tiv thaiv kev nyab xeeb ntawm qhov system. Thaum cov roj hmab hose hauv cov roj hluav taws xob no tawg, cov txheej txheem hluav taws xob tuaj yeem siv tau; pov tseg cov cuab yeej tiv thaiv hauv cov roj hluav taws xob (xws li lub valve kev nyab xeeb, thiab lwm yam); thaiv cov roj Circuit Court uas ua rau cov hose tawg, thiab disconnect cov roj Circuit Court. Thaum siv txoj kev qhib Circuit Court, lub kaw lus load yuav tsum tswj ntawm 85 feem pua -95 feem pua ntawm cov ntsuas load.
Qhov thib tsib yog txoj kev nplaum.
Thaum cov roj hmab hose nrog lub siab ntawm {{0}}.0 MPa nyob rau hauv lub hydraulic system puas lawm, txoj kev sib khi yuav siv tau: so ib ncig ntawm lub hose tawg; siv anaerobic adhesive, epoxy kua nplaum, 801 kua nplaum rau qhov tawg hose Ib qho ntawm cov kua nplaum los yog 502 kua nplaum (qhov ntev ntawm cov txheej yog li ntawm 2-3 npaug ntawm qhov ntev ntawm qhov tawg); siv cov ntaub nplaum los yog cov ntaub pua plag rau pawg 4-5 cov txheej txheej (txhua txheej yuav tsum tau nplaum); Ob qhov kawg ntawm lub canvas strips yog knotted; nws tuaj yeem siv tom qab kho rau 15-20 feeb.
Qhov thib rau yog txoj kev hloov pauv.
Nyob rau hauv lub hydraulic system, roj hmab hoses nyob rau hauv tib lub roj Circuit Court muaj tib yam specifications, tab sis dais txawv roj pressures. Ruptured hoses feem ntau yog hoses nrog roj siab. Yog li ntawd, txoj kev hloov pauv tuaj yeem siv tau: kev sib txuas yooj yim lossis kev sib txuas ntawm cov hoses tawg; hloov cov roj kav ntawm cov roj inlet thiab qhov hluav taws xob.
Tag nrho cov nyob rau hauv tag nrho cov, txoj kev yog ib tug txheej txheem thaum muaj xwm ceev, thiab lub siab-siab hose yuav inevitably poob nws thawj Performance index. Yog li ntawd, hloov tom qab qhib, thiab cov cuab yeej siv tseem nyob hauv qhov zoo. Hauv kev siv tswv yim, hose rupture yuav tsum raug zam, thiab kev tshuaj xyuas thiab tu yuav tsum tau ua.
