Ko Multiple Activation Bypass Valve (MCBV) Inoshanda sei?

Panyaya yekurasika kutenderera panguva yekuchera, kushandiswa kweakawanda activation ye bypass valve inogona kuwana yakawanda yakakwira concentration, yakakura particle plugging materials uye kusvina simende plugging pasina kudhonza kunze kweBHA.

Kuvhurwa kwevhavhavhavha: usati wavhara pluging, tanga wadhonza kunze kweBHA kune yakachengeteka tsime chikamu uye kudonhedza bhora rinoshanda. Kana bhora rinoshanda riri pachigaro chebhora, pombi yakaderera inobata zvishoma nezvishoma kudzvinyirira. Kana mutsauko wekumanikidza unosvika 0.7-1.5mpa, kudzvanywa kwekubata kudzvinyirira kwakakura kupfuura simba remuchirimo kuita kuti sleeve inotsvedza iende pasi. Kana sleeve inotsvedza ichidzika kusvika kune yakaderera muganhu chinzvimbo, gomba rekupfuura remushonga unotsvedza rinoenderana negomba rekupfuura repamusoro sub, uye vharafu yekupfuura inovhurwa. Wedzera kuchinjika kune yekutamisa yekuvaka, pombi mu plugging slurry, uye iyo plugging slurry inopinda muyero yekuvuza kubva pagomba rekupfuura rekuvhara zvakananga. Kana pombi yamiswa, sleeve inotsvedza ichagadzirisa zvakare pasi pesimba rechirimo, uye vharafu inovhara inovhara yega, kuitira kuti kuderedze iyo inogona kunge yakaita U-yakaita pombi maitiro kana matambudziko ekudzora matsime. Kana gomba rekunzvenga richida kuvhurwazve, pombi inogona kushandiswa zvakare zvishoma nezvishoma.

Kuvhara kwe-by-pass valve: mushure mekupedzwa kwekugadzira plugging, kana zvichidikanwa kuti utangezve kuchera, donhedza mumabhora maviri akavharwa. Kana bhora rakavharwa rasvika paburi rekupfuura, rinotanga kubata kudzvanya uye zvishoma nezvishoma rinowedzera kudzvanywa. Kana mutsauko wekumanikidza unosvika kune yakagadziriswa shear kudzvanywa kweiyo activated bhora (iyo dhizaini dhizaini ndeye 10 MPa), iyo activated bhora inogerwa uye ichipfuura nepakati pechigaro chebhora, uye bhora rakabatidzwa uye rakavharwa bhora zvese zvinowira mubhasiketi rebhora. Sleeve inotsvedza inokwira ichienda kumusoro pasi pechiito chesimba rechirimo, gomba rekunzvenga remaoko rinotsvedza rinozunguzwa neburi rekubypass rejoinhi rekumusoro, vharafu yekupfuura yakavharwa uye kuchera kunotangazve.

Mukushanda kwetsime rakachinjika, rinotungamira mutsime uye rakatsauka zvakanyanya, kushandiswa kweMultiple activation bypass valve, iyo inogona kuona kusimuka kwakakura kuyerera uye matombo ekucheka mubhedha kugezesa, izvo zvisingangonatsiridza zvakanaka kugezesa, asiwo inodzivirira midziyo yepasi uye maturusi. , Kana zvichidikanwa, vhura gomba rekupfuura kuti uchenese madziro emukati ekesi kana BOP boka.

Kana iyo bypass system inoda kuvharwa, isa mabhora maviri akavharwa, svina bhora rekukiya nekubata kudzvanywa (iyo dhizaini yekumanikidza yekuvhara bhora extrusion ndeye 7MPa), uye ramba wakabata kumanikidza kuvhara iyo bypass system.
