A hydraulic torque wrench isimba rekushandisa rakagadzirirwa kushandisa torque pane yekusimbisa kuti iwane kusimba kwakaringana kana kusunungura kwekubatanidza kuburikidza nekushandisa hydraulics. Iyo torque wrench inoiswa kune nati zvakananga kana pamwe chete neanokanganisa socket. Hydraulic torque wrenches inoisa yakafanotemerwa, inodzorwa huwandu hwetorque kune yakanyatsogadziriswa yekusimbisa.
Iyo hydraulic torque wrench yakagadzirwa kutanga kwema1970. [1] Pfungwa ye hydraulic powered torque wrench yakatanga kuunzwa pamusika imwe nguva mukutanga 1960s mune yekare fomu, uye akati wandei mafambiro akakosha akagadzirwa nevagadziri kubva panguva iyoyo izvo zvakapa kufambira mberi kukuru muhunyanzvi uye kushandiswa kwezvishandiso zvakapfuura. iyo yekutanga pfungwa chishandiso.Zvishandiso zvitsva zvinopa mabhenefiti akadai seakareruka maredhiyo, madiki emhuno eradius madiki ekukodzera munzvimbo dzakasimba, kushandisa ekunze alloys, actuation zvinokonzeresa pachishandiso pachacho, akawanda-nzvimbo maitiro ekuita nhengo, 360 ° × 360 ° hose swivels, uye kugona kumhanya. maturusi akawanda panguva imwe chete kubva kune rimwe simba pack.
Kune marudzi maviri e hydraulic torque wrenches: square drive uye low profile. Zvichienderana nekushandiswa, imwe kana imwe ichave yakanakisa chishandiso chekushandisa.
Hunhu hukuru hwe hydraulic torque wrench iyo inoiisa parutivi kubva kune mamwe magetsi emagetsi ebasa rakafanana ndeyekuti (1) inofanirwa kugadzira torque ichishandisa hydraulic nzira chete (2) inofanirwa kunge ichizvirova yega, uye (3) inofanirwa kusanganisira chaiyo. nzira yekuona huwandu hwe torque yakaiswa.
Muna 1985, iyo Research Council pamusoro peStructural Connections tsanangudzo yakabvumira kushandiswa kweiyo calibrated wrench nzira yekuisa, asi nekutaura kwakajeka kwezvinodiwa nzira uye zvisingakwanisi.
Mune yakagadziriswa wrench nzira iyo wrench inogadziriswa kana kugadziridzwa kuti ivhare kana torque yaunoda yasvika. Iwo ma hydraulic haana chiyero che calibration maitiro, asi maitiro anotevera manyorerwo torque zviyero ASME B107.14-2004, ISO 6789:2003, kana mamwe akafanana.[2]
Vamwe vagadziri vanoshandisa kubata pawl dhizaini kuchengetedza wrench yakakiyiwa pachinzvimbo pamberi pega yega sitiroko yemagetsi, nepo vamwe vachishandisa akasiyana madhizaini, ane zvikanganiso zvakasiyana uye zvakanakira.
Hydraulic torque wrenches dzinowanzopa huchokwadi hwe ± 1-3% uye dzine chiyero chepamusoro chekudzokororwa zvichiita kuti dzinyatsokodzera maapplication apo mabhaudhi mahombe anosanganisirwa uye chiyero chepamusoro chechokwadi chinodiwa.[3]
A hydraulic torque wrench yakanyarara zvakanyanya, yakareruka uremu uye yakaringana kupfuura pneumatic impact wrenches inokwanisa kuburitsa torque yakafanana, zvichiita kuti ive imwe nzira inokwezva kune vakawanda vashandisi kune yakanyanya ruzha uye inorema yekukanganisa wrenches kana torque multipliers iyo yaimbove ndiyo yega sarudzo inoshanda kushanda nenzungu dzakakura kwazvo uye mabhaudhi kusvikira hydraulic torque wrench yaunzwa. Iyo Hydraulic Torque wrench yakagadzirwa muna 1968 naGeorge A. Sturdevant.
Hydraulic bolt tensioners ndiyo imwe nzira kune hydraulic torque wrenches, asi kwete seanowanzo shandiswa.
