Rodless Cylinder is the main shift drive component for the operation and travel of large well repair rigs or other heavy equipment, and its importance is self-evident. Through precise design and complex working principle, the cylinder realizes precise control of each gear of the hydraulic transmission, thereby ensuring the smooth operation and efficient operation of heavy equipment.
The structure of the rodless cylinder is relatively complex, but the design is exquisite. It is mainly composed of cylinder body, piston, stop ring, spring, push rod and other parts. There are multiple grooves in different positions inside the cylinder body, in which the piston can move, and the position of the piston determines the output of the cylinder, thereby controlling the mechanical shifting action. The combination of the stop ring and the spring plays a role in positioning and buffering, ensuring the stability and accuracy of the piston during movement.
In terms of 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 group of stop rings and pistons in the cylinder. These movements include the step-by-step extension and retraction of the piston push rod, and the step-by-step movement of the step valve core of the hydraulic transmission. These actions then control the oil inlet and outlet of the hydraulic clutches of each gear of the hydraulic transmission, thereby controlling the clutch state of each gear clutch, and finally realizing the shifting of the hydraulic transmission.
The compressed air source for the piston of the shift cylinder and the stop rings at each level to generate the action is realized through the operation of the eight-position shift valve. In the air circuit system composed of the cylinder and the shift valve, the shift valve is the control element and the shift cylinder is the actuator. The structure and working principle of both are relatively complex, and they are precision components, and the requirements for the working medium (compressed air) are also high.
In addition, the rodless cylinder also has high reliability and durability. It uses high-quality materials and advanced manufacturing processes to ensure the stable operation and long service life of the cylinder under harsh working conditions. At the same time, the cylinder also has good sealing and buffering performance, which effectively prevents leakage and impact.
In summary, the rodless cylinder is the core component of the shift drive of heavy equipment, with complex structure, precise working principle, high reliability and durability. It plays a vital role in large-scale workover rigs and other heavy equipment, providing a strong guarantee for the smooth operation and efficient operation of the equipment.
