What are the classifications of hydraulic tools?


Hydraulic tools are a common tool type, with light weight, small size, small movement inertia, fast response speed, convenient operation and control, and can be conveniently and flexibly arranged according to needs. So what are the types of hydraulic tools? How to use various hydraulic tools? The following editor will introduce to you the types and usage methods of commonly used hydraulic tools.


Hydraulic wrench A conventional hydraulic torque wrench kit is generally composed of a hydraulic torque wrench body, a special pump station for hydraulic torque wrenches, a dual high-pressure hose and a high-strength heavy-duty sleeve. Uses: Shipbuilding, petrochemical, wind power, hydropower, thermal power, mining, machinery, steel plants, rubber, pipelines and other construction maintenance and emergency repair work. Usage: Press the RUN button to advance, release, and reset. Repeat several times. When the wrench rotates without abnormality, put the wrench on the nut to confirm the direction of the wrench, and repeat the forward and backward cycles of the cylinder until it is tightened or removed. Nut. Model specifications: M36 nut hexagonal opposite side 55, M42 is 65, M48 is 75. M36 bolts, strength grade 8.8, torque 1764Nm; strength grade 10.9., torque 2453Nm; strength grade 12.9.


Hydraulic jack A jack that uses a plunger or a hydraulic cylinder as a rigid lifting member. Simple lifting equipment generally only has a lifting mechanism for lifting heavy objects. Simple structure, light weight, easy to carry and easy to move. Uses: power maintenance, bridge repair, heavy lifting, static pile driving, foundation settlement, bridge and ship repair and construction, especially in road and railway construction, mechanical adjustment, equipment disassembly, etc. Usage: Reasonably choose the focus point of the jack, the bottom surface should be leveled, put it in place, tighten the oil drain screw on the oil pump, move the handle in and out of the upgrade control head, and press the handle to start work. Model specifications: thin hydraulic jack models: JRCS, RCS; flat jack models: QB, QBS, etc. Ultra-thin hydraulic jack models: JRSM, RSM. The ultra-thin jack model has STC.


Hydraulic bolt tensioner, also known as hydraulic tensioner, power element, its function is to convert the mechanical energy of the prime mover into liquid pressure energy, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. Uses: Widely used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. Usage: Connect the bolt tensioner, the oil pipe and the manual hydraulic pump, the dry running will use gravity to reset the piston rod, and put the bolt tensioner on the nut to be locked. Use a hand pump to push out the piston rod of the bolt tensioner, and use the handle provided with the bolt tensioner to unscrew the nut to be locked. Then loosen the handwheel on the unloading valve of the hand pump counterclockwise, then use gravity to reset the piston rod, and then unload the bolt tensioner in the reverse direction of “3″ above.


The hydraulic puller is a new ideal tool to replace the traditional puller. It has the characteristics of compact structure, flexible use, convenient carrying and operation, less labor-saving, and less restricted by the site. It is suitable for various maintenance places. Press the starting lever to move forward, and the claws move back correspondingly to pull out the object being pulled. Uses: suitable for factories, ships, repair places. Usage: Tighten the oil return valve rod clockwise before use, adjust the claw seat until the claw catches the object being pulled, tilt the piston starting rod back and forth to move forward steadily, and the claw hook backs back accordingly to pull the object The object is pulled out. Model specifications: Models are PH106, PH108, PH110, PH113, PH116, PH206, PH210, PH213, PH216. Different models correspond to different tonnage, reach, tension and oil volume of the cylinder.


Hydraulic flange separator The required size of the insertion port is only 6mm, and the maximum separation amount is 65mm. The design of the stepped cantilever allows each step to bear the full load. It is ensured that the separating piece is close to the flange when it is opened, and will not expand excessively. It will automatically return to position when it is closed. It has fewer moving parts, is durable and easy to maintain. Uses: Widely used in petrochemical, electric power, steel mills and other fields, suitable for maintenance, overhaul, testing and valve replacement applications. Usage: measure the gap size, adjust the tip, insert the gap, and then shake the rocker. Model specifications: UFS-150 has a maximum separation force of 15 tons, and UFS-150D has a maximum separation force of 2*15 tons.


Hydraulic nut cutters Hydraulic nut cutters are also called nut cutters. In some industries, for corroded nuts that cannot be disassembled, nut cutters can be used to cut easily without damage to the anchor rod. It can be used next time. Uses: mining, industrial and explosion-proof environments. Usage: Open the oil filling screw plug, fill the manual oil pump box with oil, and close the unloading valve. Put the head hole of the cutter into the nut to be broken, and lay it flat. Press the manual oil pump to push the wedge out to the nut, split the nut and damage the bolt thread. When you hear the cracking sound of “bang”, stop pressing. Unscrew the unloading valve, return to the original position after the chopping knife, and remove the chopper. Model specifications: Models are LP-20, LP-42, LP-61, LP-72, LP-82, LP-103, LP-115, LP-160, and the destructive power corresponds to 75, 200, 400, 600, 900, respectively , 1400, 3000 and 5000 (unit KN), the bolt range ranges from M6-M110.
