Ma hydraulic torque wrench ndi chida champhamvu chomwe chimapangidwa kuti chigwiritse ntchito torque pa chomangira kuti chikwaniritse kumangika koyenera kapena kumasula kulumikizana pogwiritsa ntchito ma hydraulics. Wrench ya torque imagwiritsidwa ntchito ku nati mwachindunji kapena molumikizana ndi socket. Mawotchi a hydraulic torque amayika torque yodziwikiratu, yoyendetsedwa bwino pachomangira chopaka mafuta bwino.
Wrench ya hydraulic torque idapangidwa koyambirira kwa zaka za m'ma 1970. [1] Lingaliro la hydraulic powered torque wrench lidayambitsidwa koyamba pamsika nthawi ina kumayambiriro kwa zaka za m'ma 1960 m'mawonekedwe akale, ndipo zotsogola zingapo zapangidwa ndi opanga kuyambira nthawi imeneyo zomwe zidapititsa patsogolo kwambiri ukadaulo ndi kugwiritsa ntchito zida kupitilira apo. chida choyambirira cha lingaliro.Zida zatsopano zimapereka zopindulitsa monga zolemetsa zopepuka, miyeso yaying'ono ya mphuno kuti igwirizane ndi malo olimba, kugwiritsa ntchito ma alloys achilendo, zoyambitsa ma actuation pa chida chokha, mamembala amitundu yambiri, 360 ° × 360 ° hose swivels, komanso kuthamanga. zida zingapo nthawi imodzi kuchokera pa paketi imodzi yamagetsi.
Pali mitundu iwiri ya ma hydraulic torque wrenches: square drive ndi low profile. Kutengera kugwiritsa ntchito, imodzi kapena inayo idzakhala chida chabwino kwambiri chogwiritsa ntchito.
Makhalidwe akuluakulu a hydraulic torque wrench yomwe imayisiyanitsa ndi ma wrench ena opangidwa ndi mphamvu zofananira ndikuti (1) imayenera kupanga torque pogwiritsa ntchito ma hydraulic okha (2) iyenera kukhala yodzigudubuza yokha, ndipo (3) iyenera kuphatikiza yolondola. njira yodziwira kuchuluka kwa torque yomwe imagwiritsidwa ntchito.
Mu 1985, kafukufuku wa Research Council on Structural Connections adalola kugwiritsa ntchito njira yolumikizira wrench, koma ndi mawu omveka bwino a zofunikira za njirayo ndi malire ake.
Mu njira yolumikizira wrench, wrench imawunikidwa kapena kusinthidwa kuti itseke pamene torque yomwe mukufuna ifika. Ma hydraulic alibe njira yowongolerera, koma mchitidwewo umatsatira miyeso yamakokedwe apamanja ASME B107.14-2004, ISO 6789:2003, kapena zofanana. [2]
Opanga ena amagwiritsa ntchito kapangidwe ka pawl kuti asunge wrench yotsekedwa pamalo aliwonse amagetsi asanayambe, pomwe ena amagwiritsa ntchito mapangidwe osiyanasiyana, omwe ali ndi zolakwika ndi zabwino zake.
Mawotchi a torque ya Hydraulic amapereka kulondola kwa ± 1-3% ndipo amakhala ndi kuchuluka kwa kubwerezabwereza komwe kumawapangitsa kukhala oyenera kugwiritsa ntchito pomwe ma bawuti akulu amakhudzidwa komanso kulondola kwakukulu kumafunika.[3]
Wrench ya hydraulic torque ndi yabata kwambiri, yopepuka komanso yolondola kwambiri kuposa ma wrenches a pneumatic omwe amatha kutulutsanso torque yofananira, zomwe zimapangitsa kuti ikhale njira yosangalatsa kwa ogwiritsa ntchito ambiri ku ma wrenches okwera kwambiri komanso ovuta kwambiri kapena ma torque multiplier omwe kale anali njira yokhayo yopangira ma torque. kugwira ntchito ndi mtedza waukulu kwambiri ndi ma bolt mpaka wrench ya hydraulic torque idayambitsidwa. Wrench ya Hydraulic Torque idapangidwa mu 1968 ndi George A. Sturdevant.
Ma hydraulic bolt tensioners ndi m'malo mwa ma hydraulic torque wrenches, koma osati momwe amagwiritsidwira ntchito nthawi zambiri.
