Publish Time: Author: Site Editor Visit: 29
Rodless Cylinder, as the main shift drive component for the operation and travel of large well repair machines or other heavy equipment, plays an important role in the field of industrial automation with its unique working principle and high-efficiency performance.
I. Working principle
The rodless cylinder inputs compressed air into the cylinder through different air inlet holes on the cylinder sleeve to control the logical combination movement of a set of stop rings and pistons in the cylinder. This logical combination movement enables the piston push rod to extend and retract step by step, thereby driving the step valve spool of the hydraulic transmission to move step by step. The movement of the step valve spool controls the oil inlet and outlet of the hydraulic clutch of each gear of the hydraulic transmission, thereby realizing the shifting of the hydraulic transmission.
II. Structural features
The structure of the rodless cylinder is relatively complex, but the design is exquisite. It is mainly composed of cylinder sleeve, piston, stop ring, push rod and other components. There are multiple air inlet holes on the cylinder sleeve for inputting compressed air. The piston and stop ring realize logical combination movement through precise design. The push rod is connected to the step valve core of the hydraulic transmission to transmit the movement of the cylinder to the transmission.
III. Application scenarios
Rodless cylinders are widely used in heavy equipment that requires precise shifting, such as large well repair machines, engineering vehicles, etc. In these equipment, the accuracy and stability of shifting are crucial, and rodless cylinders have become the preferred shifting drive components for these equipment with their precise control capabilities and efficient performance.
IV. Advantage Analysis
Precise control: The rodless cylinder achieves precise shifting control through logical combination movement, ensuring the accuracy and stability of shifting.
Efficient performance: The efficient use of compressed air in the cylinder makes the shifting process quick and smooth, improving the working efficiency of the equipment.
Compact structure: The rodless cylinder has a compact design and a small footprint, making it suitable for installation in equipment with limited space.
Durable and reliable: Due to the use of high-quality materials and precise manufacturing processes, the rodless cylinder has a long service life and high reliability.
5. Maintenance Technology
In order to ensure the normal operation of the rodless cylinder and extend its service life, regular maintenance is required. The maintenance content mainly includes the following aspects:
Sealing inspection: Regularly check the sealing performance of the cylinder to ensure no leakage.
Cleaning and maintenance: Clean the dirt and impurities on the surface and inside of the cylinder to keep the cylinder clean.
Lubrication maintenance: Lubricate the sliding parts of the cylinder to reduce friction and wear.
Pneumatic system inspection: Check whether the pressure of the pneumatic system is normal to ensure that the cylinder can work normally.
