Hydraulic jack or hydraulic cylinder is one of the most widely used equipment in the industry, which is often used in industrial machinery and for lifting heavy objects. It is necessary to have a comprehensive definition for hydraulic jack. A hydraulic cylinder is a device that is made according to Pascal's law and uses non-compressible liquids.
Incompressible liquid (mostly oil) inside a cylindrical environment with a little pressure to the cylindrical environment. The bigger one enters and hits the piston in it. The pressure force that the oil puts on the piston, eventually leads to the object and device rising above the cylinder.

To better understand the working procedure of the hydraulic jack, it is better to understand its internal components and their relationship with each other. In the internal structure of this type of jack, two cylinders with different cross-sections, an incompressible liquid and a piston are placed. .
The oil in the first cylinder enters it with a low pressure, and due to its incompressibility, it enters the larger cylinder at a high speed and pressure. Oil hitting the piston with high pressure eventually causes the equipment to rise on the cylinder. Of course, there are other parts inside the hydraulic jack, such as the shaft, cylinder, cylinder nut and sealing parts.
Because of the incompressibility of liquids, they are used to transform and transfer work. For example, this property of liquids is used in the design of simple machines with which it is possible to obtain a great resistance force with a small driving force. One of the most widely used liquids is oil. A hydraulic jack is a device that applies force to a cylinder that contains oil and causes the oil, which is incompressible, to be transferred to another cylinder that is larger. and the oil puts pressure on the piston of the big cylinder and causes the load to move on it. Cranes or other machines have such a mechanism. The noteworthy point is that the small force that the piston enters causes pressure on the larger piston and causes the load to move on the large cylinder.
Hydraulic jack is also called hydraulic motor. This type of jack is used in both industrial applications such as hydraulic presses, machinery packaging, cranes and forging, and in mobile equipment such as construction equipment and agricultural and marine equipment.
Hydraulic jack in comparison With mechanical systems and pneumatic and electric jacks, they are more powerful, simpler and more durable. Nowadays, the use of all kinds of jacks is useful for many people. One of the jacks that is widely used in the industry and repairs of many machines today is a hydraulic jack that has different parts.

Simply put, the meaning of hydraulics is to be able to do something by pressurizing liquids. This system can be used in open and closed form. When water is used to turn the mill, in fact, an open hydraulic system is used, that is, during it, only water is used in the liquid. It has been used once.
In a closed hydraulic system, the desired liquid is placed in a fixed and defined circuit and its movement is limited to the same space. In these cases, the desired liquid is usually oil. This system is used in the structure of this type of jack. The hydraulic system is used in the braking of cars, giant cranes, excavators, mobile bridges, aviation industries, etc. This system has a simple design, is easy to use, has the ability to increase power, has good flexibility, and has high efficiency.

1- Hydraulic jacks have different designs and generally do not require a lot of space for operation. 2- Their design is simple and they are easy to use.
3- They are considered the best option for moving and lifting heavy objects.
4- They have a lighter weight than other jacks.

Types of hydraulic jacks have many applications in various industries. It can be said that wherever there is a need to raise and lift objects in the automotive industry, traces of an oil jack can be seen. Forklifts, machinery and equipment for road construction, mining and agriculture, dumpers, elevators, drilling industries, architecture, tower construction of refineries... all of them use this system in some way for different purposes.
This type of jack is used to move objects. This jack has many uses, which can be used in heavy machines such as tractors, cranes, etc., which is very practical and makes it easy to do things. The hydraulic cylinder for moving tires and heavy machines is mainly made of jack is used These jacks are available in different models due to their diversity in efficiency and use, each of which has a different length and diameter, and each of them has special features and characteristics, and can be used for different applications. They used it.
It should be said that hydraulic cylinders or linear actuators are divided into three types. Displacement cylinders, single-action cylinders, multi-action cylinders, but these cylinders have problems such as incorrect installation, non-axial loading, internal and external leaks, etc. The hydraulic cylinder rod can withstand a lot of pressure. The reason is that the pipe must have a sufficient and suitable diameter. The internal diameter of hydraulic jacks and piston rod are 125 and 75 mm.
These cylinders and jacks in this size are used to move loads up to a certain weight. If we want to say the components of this jack, including two screws at the beginning and end of it, the use of a restraining rod, welded covers, etc. is.

The telescopic jack is known as one of the most widely used types of hydraulic jacks. You may also know them as multi-stage cylinders. Several tubular piston rods are considered in their design, which are known as sleeves.
The number of sleeves reaches four to five numbers, which have different sizes and diameters. Their diameter is such that they fit inside each other. They are designed and marketed as one-sided and two-sided. They are more expensive than other types of jacks. These jacks are used in the construction of elevators and unloading machines.
قیمت جک هدرولیک و عوامل تاثیرگذار بر آن
The price of hydraulic jack varies depending on its type, size, power and application. Some of the factors affecting the price are:
Type of jack: single-sided, double-sided, electric, and telescopic jacks have different prices.
Power and capacity of the jack: jacks that have the ability to lift heavier weights have a higher price.
Build quality and brand: Jacks that are made of high-quality materials and produced by reputable brands are usually more expensive.
