What is Hydraulic Piston?
A hydraulic piston is a component used in a hydraulic system. These pistons, which are generally cylindrical in shape, are used to produce mechanical force using the pressure of hydraulic fluid. In hydraulic systems, high pressure fluid produced by a hydraulic pump is applied to one side of the piston. This pressure moves the piston, creating a force that pushes or pulls a mechanism or load on the opposite side.
Hydraulic pistons are located within the cylinder, usually with a leak-proof seal. The seal is an important component that separates the pressure of the hydraulic fluid on one side of the piston from the other, thus allowing the piston to move effectively.
Hydraulic pistons are used in a variety of applications, from industrial machinery to automotive systems. They are known for providing powerful and precise motion control.
Hydraulic Cylinders Hydraulic energy is converted to linear motion (mechanical energy) with the help of a cylinder.
HYDRAULIC CYLINDER What are the Types?
SINGLE ACTING CYLINDERS
It is the type of cylinder in which hydraulic fluid is applied to the piston from one direction. The return of the piston to the reverse position is provided by external forces (spring, weight, etc.).
DOUBLE ACTING CYLINDERS
It is a type of cylinder in which hydraulic fluid is applied to the piston from two directions. The forward and backward movement of the piston is provided by the pressure fluid effect. It is the most commonly used type of cylinder, as jobs are usually required in both directions.
TELESCOBIC CYLINDERS
It is used in places where high stroke is required. It is the most important reason for not to take up much space. It consists of pistons of different diameters, nested together. It is usually done with a single effect. It is used very often in construction machinery and tipper vehicles.
PILLOW ROLLERS
Especially in cases where the piston speed exceeds 6m / min and when moving heavy objects, impact occurs at the end of the piston stroke. These pulses reduce the working life of the circuit elements. It may also cause the work done to be irregular. Therefore, impact is an undesirable feature in hydraulic systems.
In such cases, cylinders are used at the end of the course to slow down the piston speed and prevent shocks. These types of cylinders are called padded cylinders. Cushioning process; cushioning bushing and tapered cushioning journal. At the end of the course, the section where the fluid passes is narrowed and the speed is reduced. Padded rollers can be single-sided or double-sided padded.
ROTARY CYLINDERS
Rotary cylinders, also called angular motors, are used to achieve angular rotational movements of 90,180,270,360 degrees. There are toothed or winged types.
GEAR TYPE IS ROTARY CYLINDER
Rack gear is opened to the piston rod. As a result of the back and forth movement of the piston, it turns the rack gear toothed straight or helical gear opened to the piston rod and creates angular motion.
WINGED TYPE ROTARY CYLINDER
The fluid sent into the cylinder causes the wing to rotate. On the other hand, hydraulic fluid is applied for the back movement of the wing. Thus, angular rotation movement is obtained. Wing-type rotary cylinders are not used at high torques
Issues to Consider When Choosing Hydraulic Piston
Some important issues to consider when choosing a hydraulic piston are:
1. **Application Requirements**: First, the requirements of the application in which the hydraulic piston will be used must be determined. These requirements may include factors such as the amount of load the piston must carry, its speed, frequency, and operating environment.
2. **Pressure and Force Capacity**: The maximum pressure and force values that the piston must carry are an important factor in selection. These values must be taken into account to ensure safe and effective operation of the piston.
3. **Size and Geometry**: The size and geometry of the piston must be compatible with the physical constraints of the application. These may include the dimensions of the area in which the piston will be mounted, travel distance, and other mechanical constraints.
4. **Material and Durability**: The material from which hydraulic pistons are made has a great impact on their durability and performance. Materials suitable for the operating conditions of the application should be selected. For example, wear-resistant steel alloys or special coatings can ensure long-lasting and reliable performance.
5. **Sealing**: The sealing properties of hydraulic pistons are very important. The quality and durability of the seals must be taken into account to prevent fluid leakage and ensure effective piston operation.
6. **Ease of Maintenance**: The selected hydraulic piston should be easy to maintain and repair. This may include factors such as accessibility of parts and complexity of disassembly and assembly.
7. **Price and Cost**: Finally, the cost of the hydraulic piston should also be considered. But instead of focusing only on price, other factors such as long-term performance, durability and maintenance requirements should also be taken into account.
Considering all these factors, choosing a suitable hydraulic piston can help you build a safer and more efficient hydraulic system.
How to Maintain Hydraulic Piston?
Regular maintenance of hydraulic pistons is important to ensure long-lasting and reliable performance. Here are some general steps for maintaining hydraulic pistons:
1. **Cleaning**: It is important to remove dirt and contaminants around and on the piston. This ensures proper piston operation and reduces the risk of wear or leakage. A clean cloth or a suitable cleaning solution can usually be used for cleaning.
2. **Lubrication**: It is important that the seals and moving parts of the hydraulic pistons are properly lubricated. This prevents fluid leakage and reduces piston friction, providing more efficient operation. The lubrication requirements of the piston must be carried out in accordance with the lubrication instructions specified by the manufacturer.
3. **Tightness Check**: The sealing gaskets of the hydraulic piston should be checked regularly. If there is any damage, wear or leakage, the seals must be replaced. This prevents fluid leakage and increases the efficiency of the piston.
4. **Corrosion Prevention**: It is important to protect hydraulic pistons against rust and corrosion. Especially for pistons used outdoors, protective coatings or anti-rust oils can be used.
5. **Connecting Parts**: The connecting parts of the hydraulic piston, nuts and bolts should be checked regularly. Loose or damaged fittings can pose a potential risk to the safety and performance of the piston.
6. **General Check**: The general condition of the hydraulic piston should be reviewed periodically. If there is any damage, deformation or wear, the problem must be repaired and parts replaced if necessary.
7. **Periodic Maintenance**: It is important to create regular periodic maintenance plans for hydraulic pistons. These plans should include checking, cleaning and maintaining the piston at regular intervals.
These maintenance steps are important to ensure long-lasting and reliable operation of the hydraulic piston. If any problems are detected, it is important to make the necessary repairs as soon as possible.
