The combined hydraulic cylinder is a new hydraulic cylinder that has emerged in recent years and is also a hydraulic cylinder produced by engineering and application needs. Dalan Hydraulic System tells you that there are currently two types of combined hydraulic cylinders:
1. Piston hydraulic cylinder
1 Composition: Two piston hydraulic cylinders are used to form a combined hydraulic cylinder, wherein the piston rod of one piston hydraulic cylinder is the cylinder of another piston hydraulic cylinder.
2 Features: a, reliable work, stable performance, simple structure, can achieve a combination of multiple pressure chambers;
b. It is convenient to realize speed control, especially to meet the various speed requirements of the large hooks of drilling rigs and workover rigs.
3 Scope of application: Combined hydraulic cylinders for large hydraulic equipment such as hydraulic energy storage oil drilling rigs and hydraulic energy storage oil workover rigs.
4 Experience: Provide a combined hydraulic cylinder for processing, maintenance and control of large hydraulic equipment such as hydraulic energy storage oil rigs and hydraulic energy storage oil workover rigs.
5 Disadvantages: It does not have the functions of large hydraulic cylinders, long strokes and other hydraulic cylinders. Suitable for small power, short stroke and other power and motion needs.
2, cylinder combined hydraulic cylinder
1 Principle and composition: The combination of multi-section cylinder and cylinder tube is conical surface meshing and positioning connection; the fastener for coupling is hydraulic nut fastening technology; the piston sealing structure adopts two-stage alternating sealing technology.
2 Application advantages: a, the length of the combination of at least two cylinders is several times the length of the conventional single cylinder, as long as the length that can be achieved by the piston rod can be matched with it, so as to achieve the long stroke action of the hydraulic cylinder and constant The ideal value of the output force;
b. It is easy to install, adjust, disassemble and overhaul, especially in the installation of the installation, the difficulty of disassembly, or the use of special work places;
c. It can directly reduce the use cost, and the inner cylinder damage or wear which will inevitably occur in the hydraulic cylinder. This structure type can repair or update only a certain cylinder cylinder without replacing the full-length cylinder.
3 Disadvantages: It does not have the functions of large hydraulic cylinders, long strokes and other hydraulic cylinders. Suitable for small power, short stroke and other power and motion needs.
