Hydraulic tools: photo, history, safety when working with a hydraulic tool

Every day people, sometimes without noticing it, use a hydraulic tool. What is this? This is a manually used special mechanism that helps significantly speed up and alleviate various types of tasks. Each of us, one way or another, came across such a device. The secret is that the mechanism of operation of hydraulic assistants is based on this principle: the simpler - the more reliable.

Where can I see the work of such devices

In addition to working on the same principle of jacks, the work of a hydraulic tool can be seen in the rescue of the Ministry of Emergency Situations, special forces, firemen. In the case of road traffic accidents, the fate of many people depends on how quickly a person is rescued from a damaged car. Rescuers, making the release of people from the "iron captivity", actively use a hydraulic tool.

Working on the same principle of the press allows you to deform the metal parts of the car. The metal racks of the roof of the car and many other iron parts are cut with sufficient ease by hydraulic scissors . Such a tool does not emit sparks when working with metal, excludes sharp impacts on the material and the scattering of metal fragments. Safety of work is the most important requirement in carrying out this type of work. Tools that operate on a different basis do not guarantee the proper level of security.

Firemen for access to enclosed spaces where there is a fire are sometimes forced to "snack" the locks of locks, hinges of doors, grills on windows with the help of a hand tool with a hydraulic drive.
The visual work of the mechanism with hydraulic drive can be observed in the work of an excavator, bulldozer, tractor, truck crane, etc.

Hydraulic tools: photo and description

In this example, it is easy to understand the advantages, disadvantages and distinctive features of various hand tools. For example, a hydraulic car jack with its small size can lift a lot of weight. Such a device has a long service life, is unpretentious in maintenance and is distinguished by reliability.

The only disadvantage of such a jack is its weight, which stands out strongly against the background of alternative mechanisms that perform the same function. Of course, there are light, compact and more affordable options, but none of them will be able to lift more weight than its hydraulic competitor. And they will hardly manage to work the same number.

What tools are used in production

The tool with hydraulic drive is now actively used in small businesses and industrial enterprises. There are many types, types and purposes of mechanisms with a hydraulic drive. We list some of them:

• Hydraulic press by creating incredible pressure allows you to stamp metal parts. It is used in various fields: automotive, aircraft building, shipbuilding and many others.
• Hydraulic puller allows you to gently separate components and assemblies. For example, remove the bearing from the metal shaft.
• The hydraulic rail provides the required rails with the rails where necessary.
• The hydraulic pipe bender also provides the necessary position for the metal pipes.

This is not a complete list of instruments that have a hydraulic working principle. In many areas without them it is simply not possible to use other means.

History of the creation of mechanisms with hydraulic drive

The history of the creation of a hydraulic tool goes far into the past. By a similar principle, for example, in those days, water pumps worked to eliminate fires. As a single mechanism, combining in its design the presence of a hydraulic motor, a pump and a fluid distribution system, this tool has been used only for the last two centuries.

The first patented device, operating as a full-fledged hydraulic mechanism, was invented in 1795. Above his creation, the English inventor Joseph Bram worked. Two years after receiving the patent, the world was presented with the first ever hydraulic press.

Operating principle

The principle of operation of hydraulic mechanisms is two different in diameter cylinders. In each of them there is a piston corresponding to the diameter of the cylinder. Filling it is carried out by some kind of liquid. It can be oil or water. By pumping fluid from one cylinder to another, the hydraulic energy is converted into mechanical action. The resulting mechanical force has a very effective value and is sent to perform the necessary actions.

Repair and service

In the periodical maintenance and repair work, any hydraulic tool is needed. All manipulations should be conducted by persons who have the necessary qualifications for this. Maintenance includes periodic inspection of the condition of the tool, replacement of the working fluid, checking its operability and safety. Repair of the hydraulic tool is carried out in the event of replacement of the components of the mechanism, pistons, valves, bushes, hoses and so on. For the continuous and safe operation of hydraulic mechanisms, the purity of the liquid in the mechanism and the necessary sealing of the working units are important. In view of the difficult conditions in which the device is used, safety precautions should always be followed when working with hydraulic tools. It is important to notice signs in time that the tool needs repair. This sign can serve as fluid spills on the nodes of the device or a decrease in its efficiency.

Conclusion

In our time, a hydraulic tool helps to solve many complex problems in various spheres of human activity. In view of its safety, the application is in demand in places where there is a fire hazard environment during underwater works. Hydraulic mechanism, once created and manifested as a reliable assistant, firmly entered the life of a man. Every year the spheres of its application are expanding. And only the principle of work, showing excellent results, remains the same.
