DYZ-20 integrated hydraulic gear puller (puller) Product Name: DYZ integral hydraulic gear puller (Puller) Describe: the DYZ-20 integrated hydraulic gear puller (Puller) working principle of hydraulic gear puller is the forward movement of the hydraulic actuating lever, so the push rod itself is not rotating. The knuckle seat can be forward and back of controllable pitch, as long as the operation around the small swing handle, hydraulic start lever forward, hook corresponding to backward, pull out pulled objects directly with the thread. The DYZ-20 integrated hydraulic Rama (Puller) application range of hydraulic gear puller the idealized new tool is an alternative to the traditional Rama. Easy to operate, effort, without space constraints, this Rama compact structure, the use of flexible, light weight, small size, easy to carry, suitable for factories, repair sites. Third, the DYZ-20 integrated hydraulic gear puller (puller) performance parameter model specifications DYZ-5 DYZ-10 DYZ-20 DYZ-30 DYZ-50 safety weight T 5 10 16 25 45 Stroke mm 60 6060 60 100 three-jaw adjustment range (mm) 50-250 50-300 100-400 150-500 200-550 pump Rated pressure (MPa) 40 63 63 63 70 four, the DYZ-20 integrated hydraulic gear puller (Puller) use Note 1, the use of when first slotted end of the handle is set into the oil return valve stem, and tighten the oil return valve stem clockwise direction. The knuckle seat adjustment to claw hook seize the pull objects. 3, hole handle insert lift hand back and forth ruffles the piston actuating lever forward steady advance, claw hook corresponding back and pulled out pulled objects. 4, the the piston actuating lever hydraulic Ramli effective distance is only 50mm when using the extended distance shall not be greater than 50mm, stop when not pulled out, loosen the oil return valve, piston starter rod retracted go second after a good tune Repeat steps 1, 2, 3 pulled out so far. 5, purports to the piston actuating lever retracted, only need to handle slotted end of the oil return valve stem counterclockwise slightly loosen the piston starter lever spring action gradually retraction. 6, prior to use should be based on the outside diameter of the pulled objects, draw length and load force, select the corresponding tonnage hydraulic Rama avoid overloading of use, to avoid damage. 7, the hydraulic Rama -5 ℃ ~ 45 ℃ (GB443-84) N15 machine oil; -20 ℃ ~ -5 ℃ (GB442-64) synthesis of spindle oil. To prevent overload damage caused by machinery, hydraulic devices are equipped with hydraulic overloading automatic unloading valve, pulled the object exceed the rated load, overload valve automatically unloading, and instead use a larger tonnage Rama.
