Hydraulic tools are a common type of tool in our daily life. They have the characteristics of light weight, small size, small motion inertia, fast response speed, and convenient manipulation and control. It can be arranged conveniently and flexibly according to the needs, so it is deeply loved by the users.

So what are the types of hydraulic tools? How to use various hydraulic tools?

Next, TorcStark will introduce the types and usage of commonly used hydraulic tools to you.

1. Hydraulic wrench

A conventional hydraulic torque wrench kit is generally composed of a hydraulic torque wrench, a special hydraulic pump station for hydraulic torque wrenches, a double high-pressure hose and a high-strength heavy-duty socket.

Applications: Ship engineering, petrochemical, wind power, hydropower, thermal power, mining, machinery, steel mills, rubber, pipelines and other construction maintenance and repair work.

Operation: First connect the hydraulic wrench and the hydraulic wrench pump through the hydraulic hose, and then press the RUN button of the hydraulic wrench pump to advance, release and reset. Repeat several times, when the wrench rotates without abnormality, put the wrench on the nut. Confirm the direction of the wrench, and repeat the working cycle of the hydraulic wrench forward and backward until the nut is tightened or removed.

2. Hydraulic jack

A hydraulic jack is a jack that uses a plunger or a hydraulic cylinder as a rigid jacking member. Simple lifting equipment is generally only equipped with a lifting mechanism to lift heavy objects. It is simple in structure, light in weight, easy to carry and easy to move.

Applications: power maintenance, bridge maintenance, lifting of heavy objects, static pressure piles, foundation settlement, bridge and ship repair and construction, especially in highway and railway construction, mechanical adjustment, equipment dismantling, etc.

Operation: Reasonably choose the focus point of the jack, and the bottom surface should be leveled and placed in a good position. The hydraulic pump is connected by a hydraulic hose. If a manual hydraulic pump is connected, the hydraulic jack can be lifted or supported by pressing the handle of the manual pump repeatedly. If an electric, pneumatic or other hydraulic pump is used as the power source, the hydraulic jack can be easily lifted or supported by pressing the switch.

3. Hydraulic bolt tensioner

Hydraulic bolt tensioner, also known as hydraulic tensioner. Its function is to convert the pressure energy of hydraulic oil into tensile force on the bolt, so that the bolt can be tightened without the influence of friction.

Applications: Widely used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields.

Operation: Connect the bolt tensioner, hose and manual hydraulic pump. Idling will use gravity to reset the piston rod. Fit the bolt tensioner over the nut to be tightened. Pressurize with a hand pump to push out the piston rod of the bolt tensioner, and then use the handle provided with the bolt tensioner to unscrew the nut to be locked. Unscrew the handwheel on the unloading valve of the manual pump counterclockwise, then reset the piston rod with gravity, and finally remove the bolt tensioner in reverse.

4. Hydraulic puller

Hydraulic puller is a new ideal tool to replace traditional puller. It has the characteristics of compact structure, flexible use, convenient carrying and operation, less restrictions on site, etc. It is suitable for various maintenance places. As long as the handle slightly swings back and forth, the hydraulic starting lever moves forward, the hook claws retreat correspondingly, and the object can be pulled out.

Applications: Suitable for factories, ships and repair places.

Operation: Tighten the oil return valve rod clockwise before use, and adjust the hook seat so that the hook catches the pulled object. Tilt the piston starting rod back and forth to move forward smoothly, and the claw hook moves back accordingly to pull out the object.

5. Hydraulic flange separator

The required size of the insertion port is only 6mm, and the maximum separation amount is 65mm. The design of the step-shaped arm allows each step to bear full load. It ensures that the separator is close to the flange when it is opened, and will not expand too much, and it will automatically return when it is closed. It has fewer moving parts, durable and easy to maintain.

Applications: Widely used in petrochemical, electric power, steel mill and other fields, and suitable for maintenance, overhaul, testing and valve replacement.

Operation: measure the gap size and adjust the tip. Insert the gap, and then shake the rocker.

6. Hydraulic Nut Cutter

Hydraulic nut cutters are also called nut cutters. In some industries, for rusted nuts that cannot be disassembled, a nut cutter can be used to easily cut the bolt without damage to the bolt, and the bolt can be used next time.

Applications: Mining, industrial and explosion-proof environments.

Operation: Open the oil filling plug, and fill the pump tank with oil, and then close the unloading valve. Insert the hole of the head of the cutter into the nut to be broken, and lay it flat. Press the hand pump to push the rivet out to the nut. When the rivet is pushed into half of the nut, the hand pump must be pressed carefully, so as not to cause the rivet to quickly split the nut and damage the bolt thread due to excessive force. When you hear the cracking sound of “pop”, it means that the nut has been broken, and the pressing can be stopped.
