The principle of operation of the hydraulic cylinder

The principle of operation of the hydraulic cylinderIt is based on the use of an inconsistent fluid (usually hydraulic oil) to transmit pressure from one end of the cylinder to another, creating a linear movement. The piston inside the cylinder moves under the influence of fluid pressure, which allows various mechanical work, such as lifting, pushing or moving goods.

What is a hydraulic cylinder?

The hydraulic cylinder is an executive mechanism that converts the energy of hydraulic fluid into linear mechanical movement. It consists of several main components:

• Cylinder sleeve:The main case withstanding high pressure.
• Piston:The part moving inside the sleeve.
• Piston rod:An element that transfers the force from the piston to the external load.
• Seals:Provide the tightness between the piston and the sleeve, preventing fluid leaks.
• Entrance and output holes:Used to feed and diverted hydraulic fluid.

The main types of hydraulic cylinders

There are several types of hydraulic cylinders, the most common:

• Unilateral cylinders:The movement in one direction occurs under the action of a hydraulic fluid, and the return is under the influence of a spring or external force.
• Bilateral cylinders:Movement in both sides occurs under the action of a hydraulic fluid.
• Telescopic cylinders:They consist of several invested sections that allow you to get a large move with compact sizes.

The principle of operation of the hydraulic cylinderone -sided action

In a one -sided cylinder, a hydraulic fluid is supplied to only one cylinder cavity. The pressure of the liquid pushes the piston, moving the stem. When the fluid supply is stopped, the spring or external force returns the piston to its original position.

Unilateral cylinder scheme

1. The hydraulic fluid is supplied to the cylinder cavity.
2. The fluid pressure increases and pushes the piston.
3. The piston rod moves, performing useful work.
4. The fluid supply is stopped.
5. The spring or external force returns the piston to its original position.

The principle of operation of the hydraulic cylinderbilateral action

In a bilateral cylinder, hydraulic fluid can be supplied to both cavity of the cylinder. This allows you to move the piston in both directions under the action of hydraulic pressure.

Two -way cylinder scheme

1. To put forward the rod, the hydraulic fluid is supplied to one cylinder cavity.
2. The pressure of the liquid pushes the piston, moving the stem.
3. To draw a rod, a hydraulic fluid is supplied to another cylinder cavity.
4. The pressure of the fluid pushes the piston in the opposite direction, drawing the stem.

Advantages of hydraulic cylinders

Hydraulic cylinders have a number of advantages compared to other types of drives:

• High power:They are able to develop a large effort with compact sizes.
• Smoothness:Provide smooth and accurate movement.
• Reliability:Durable and reliable in operation.
• Universality:Can be used in various fields of industry and equipment.

Areas of the use of hydraulic cylinders

Hydraulic cylinders are widely used in various areas:

• Construction equipment:Excavators, bulldozers, taps.
• Agricultural equipment:Tractors, combines, plows.
• Industrial equipment:Presses, machines, casting machines.
• Transport:Cars, planes, ships.

How to choose a hydraulic cylinder?

When choosing a hydraulic cylinder, the following factors must be taken into account:

• The necessary effort:Determine the maximum effort that the cylinder should develop.
• Rod move:Determine the required movement of the rod.
• Working pressure:Select a cylinder designed for the required operating pressure.
• Type of cylinder:Determine which type of cylinder (one -sided or bilateral) is better suited for your use.
• Terms of Use:Consider the operating conditions of the cylinder (temperature, humidity, pollution).

Maintenance of hydraulic cylinders

To ensure reliable and durable operation of hydraulic cylinders, it is necessary to regularly maintain their maintenance:

• Checking the level of hydraulic fluid:Maintain fluid level in accordance with the manufacturer's recommendations.
• Checking for leaks:Spend the cylinder regularly for fluid leaks.
• Snack lubrication:Lubricate the cylinder rod to prevent wear and corrosion.
• Replacement of seals:Replace the seals when signs of wear or damage appear.

Company LLC Internal Mongolia Zhitsyan Construction equipment and hydraulic cylinders

LLC Internal Mongolia Zhitsyan Construction equipment available at the addresshttps://www.nmgrq.ru/, is a supplier of construction equipment and components, including hydraulic cylinders. When choosing hydraulic equipment, it is important to consider the manufacturer and product quality. The company offers a wide range of hydraulic cylinders for various construction equipment.

An example of using a hydraulic cylinder in an excavator

In the excavator, hydraulic cylinders are used to drive a bucket, arrows and handle. Consider an example of the work of the cylinder leading the bucket:

1. The operator controls the lever by supplying hydraulic fluid to the bucket cylinder.
2. The pressure of the liquid pushes the cylinder piston.
3. The piston rod is connected to the bucket through the lever system.
4. Moving the rod leads to the rotation of the bucket, allowing you to dig the soil.
5. To unload the bucket, the operator switches the lever, directing the hydraulic fluid to the other cylinder cavity.
6. The piston moves in the opposite direction, turning the bucket and pouring the soil.
