The windowed overshot chishandiso chinoshandiswa kuredza short tubular, columnar kana stepped zvinhu, senge tubing pup joints with couplings, screen pipes, loggging weighting rods, etc. Inogonawo kushandiswa pamwe chete nembambo pazasi. chechokushandisa.
1. Mamiriro epamusoro pehwindo
Iwindo rinopfuura rakasungirirwa nezvikamu zviviri zvehumburumbira yemuviri uye yekumusoro joint (zvakare yakarukwa kubatana)
Zvinoenderana nezvinodiwa zvekununura, iyo yepasi yekupedzisira yecylinder inogona kuitwa mune anotevera mana akasiyana zvimiro:
(1) Iyo spiral semi-oblique cut iri nyore kutenderera uye kusuma hove.
(2) Iyo zigzag milling shoe cut inokodzera kuseta milling kuchenesa zvinhu zvakaoma pamusoro pehove uye kutungamira hove mairi.
(3) Muromo webhero wekoni yemukati wakanakira kuunza zvakananga hove.
(4) Kuchekwa kwakafanana nekubata Batanidza kubata nepamusoro pehwindo kuti uwedzere kubata hove.
2. Kushanda musimboti wewindow overshot
Apo hove inopinda muhumburumbira uye inosundira mururimi rwehwindo, rurimi rwehwindo runowedzera kunze, simba rayo rebound rinoruma muviri wehove zvakasimba, uye rurimi rwehwindo runosungawo zvakasimba matanho, kureva, hove inobatwa.
3. Kushanda nzira yehwindo overshot
(1) Tarisa uone kana shinda kana maweld echikamu chimwe nechimwe akasimba uye akasimba. Edza kana saizi yerurimi rwehwindo uye dhayamita yemukati yemukati yakavharwa inogona kukwana hove, uye chengeta mufananidzo kuti uwedzere kuferefeta.
(2)Dirai pasi kusvika pa2~3m pamusoro pehove, wotanga pombi kugeza tsime. Zvishoma nezvishoma tenderedza tambo yekuboora kuti udzikise. Cherechedza kuchinja kwehuremu hwehuremu uye kupinda kwekona, yeuka kubata hove kuti upinde, uye utungamirire silinda kuti ipinde muhove.
(3)Ramba uchidzikisa tambo yekuboorera kuti hove dzipinde mukati memugodhi wemudziyo. Kana urefu hwezvinhu zvinodonha hupfupi, tsime rakadzika, uye zvakaoma kutonga nzvimbo yekupinda uye kuchinja kwekuremerwa kwekuremerwa, tambo yekuchera inogona kusimudzwa ne 1-2m mushure mekubata hove imwe chete, uye yozotenderera uye. kuderedzwa. Dzokorora kakawanda kuti usimudze chibooreso.
(4) Paunenge uchisimudza chibooreso, chinofanira kuitwa zvakanaka. Usagunzva hove uye urove tambo yekuchera kamwe kamwe, kuti urege kuzunungusa hove pasi uye kuwira mutsime zvakare.
