Hydraulic Torque Wrench ke eng?

Wrench ea hydraulic torque e qapiloe mathoasong a lilemo tsa bo-1970. [1] Khopolo ea "hydraulic powered torque wrench" e ile ea qala ho hlahisoa 'marakeng ka nako e' ngoe mathoasong a lilemo tsa bo-1960 ka mokhoa oa khale, 'me tsoelo-pele e' maloa e hlahisitsoe ke bahlahisi ho tloha ka nako eo e faneng ka tsoelo-pele e kholo ho thekenoloji le ts'ebeliso ea lisebelisoa hole hole. sesebelisoa sa mohopolo oa mantlha.

Lisebelisoa tse ncha li fana ka melemo e kang litekanyo tse bobebe, litekanyo tse nyane tsa radius ea nko bakeng sa ho kenella libakeng tse thata, tšebeliso ea li-alloys tse sa tloaelehang, li-actuation triggers sesebelisoa ka boeona, litho tse fapaneng tsa karabelo, 360 × 360 ° hose swivels, le bokhoni ba ho matha. lisebelisoa tse ngata ka nako e le 'ngoe ho tsoa paketeng e le' ngoe ea matla.

Ho na le mefuta e 'meli ea li-wrenches tsa hydraulic torque: square drive le boemo bo tlase. Ho ipapisitse le ts'ebeliso, e 'ngoe kapa e' ngoe e tla ba sesebelisoa se molemohali seo u ka se sebelisang.

Litšobotsi tse ka sehloohong tsa wrench ea torque ea hydraulic e e khethollang ho li-wrenches tse ling tse nang le matla a ts'ebetso e ts'oanang ke hore (1) e tlameha ho hlahisa torque e sebelisa mokhoa oa hydraulic feela (2) e tlameha ho itšehla thajana, 'me (3) e tlameha ho kenyelletsa e nepahetseng. mokhoa oa ho fumana palo ea torque e kentsoeng.

Ka 1985, Tlhaloso ea Lekhotla la Lipatlisiso mabapi le Likamano tsa Mehaho e ile ea lumella tšebeliso ea mokhoa oa ho kenya wrench e lekantsoeng, empa ka polelo e hlakileng haholoanyane ea litlhoko tsa mokhoa oo le meeli ea oona.

Ka mokhoa o lekantsoeng oa wrench, wrench e lekanngoa kapa e lokisoa hore e koalehe ha torque e lakatsehang e fihla. Li-hydraulic ha li na mokhoa o tloaelehileng oa calibration, empa mokhoa ona o latela litekanyetso tsa torque ea litaelo ASME B107.14-2004, ISO 6789: 2003, kapa tse tšoanang le tsona.[2]

Baetsi ba bang ba sebelisa moralo oa ho ts'oara li-pawl ho boloka wrench e notletsoe pele ho matla a mang le a mang, ha ba bang ba sebelisa meralo e fapaneng, e nang le liphoso le melemo e fapaneng.

Li-wrenches tsa torque tsa Hydraulic hangata li fana ka ho nepahala ha ± 1-3% 'me li na le boemo bo phahameng ba ho pheta-pheta ho etsa hore li tšoanelehe hantle lits'ebetsong moo ho amehang liboutu tse kholo 'me ho hlokahala tekanyo e phahameng ea ho nepahala.[3]

Mochine oa torque oa hydraulic o khutsitse haholo, o bobebe ebile o nepahetse ho feta li-wrenches tsa pneumatic tse khonang ho fana ka torque e tšoanang, e leng se etsang hore e be sebaka se khahlang bakeng sa basebelisi ba bangata ho li-wrenches tse matla le tse boima kapa li-multiplier tsa torque tseo pele e neng e le tsona feela khetho e sebetsang bakeng sa ho sebetsa ka linate tse kholo haholo le liboutu ho fihlela wrench ea torque ea hydraulic e hlahisoa. The Hydraulic Torque wrench e qapiloe ka 1968 ke George A. Sturdevant.

Hydraulic bolt tensioners ke mokhoa o mong ho fapana le hydraulic torque wrenches, empa eseng joalo ka ha e sebelisoa hangata.
