Classification of jacks-hydraulic tools

Jack is divided into two kinds of mechanical jacks and hydraulic jacks.
1, in principle, the principle of hydraulic jack is based on the Pascal principle, namely: the liquid pressure everywhere is the same, so, in the balance of the system, the piston above relatively small pressure is relatively small, and exert great pressure on the piston is relatively large, which can keep the stationary liquid. Therefore, through the transfer of liquid, you can get different ends of the different pressure, so that you can achieve the purpose of a transformation. We are common to the hydraulic jack is the use of this principle to achieve the transfer of force.

2, mechanical jack by mechanical principle, the reciprocating pull handle, pull claw push ratchet gap, small bevel gear drive gear, the lifting screw rotation, so that the lifting sleeve was lifting or dropping, and the lifting force function to. But not as simple as hydraulic jacks.

Safety precautions for cutting machine-hydraulic tools

Image
Installation and commissioning 1, steel straightening machine should be installed on a flat solid ground. 2, the installation of the bearing frame, the center of the bearing groove to be aligned with the guide cylinder, the straightening cylinder, the lower cutter hole or the center line of the shear gear groove, and keep straight. 3, after the installation of the machine, must check whether the electrical circuit and parts are damaged, the connection of the machine is reliable, the transmission part is flexible, confirm the error before the trial operation. 4, the first empty machine operation, check the bearing (focus on examination of the straightening cylinder bearing), hammer, knife or cutting gear is working properly. Ensure that no abnormal condition, before feeding, test straightening and cutting. safety precautions in operation 1, according to the straight bar diameter, selecting proper straightening block, traction wheel groove and the rotation speed. Straightening block di...
