1. Telescopic hydraulic cylinder

Introduction to the telescopic hydraulic cylinder: The telescopic hydraulic cylinder has two or more stages of pistons. The order of the extension of the piston in the telescopic hydraulic cylinder is from large to small, while the order of no-load retraction is generally from small to large.

Features of the telescopic hydraulic cylinder: The telescopic cylinder can achieve a longer stroke, while the retracted length is shorter and the structure is more compact. Such hydraulic cylinders are often used in construction machinery and agricultural machinery.

2. Swing hydraulic cylinder

Introduction of swing hydraulic cylinder: swing hydraulic cylinder outputs torque and realizes reciprocating swing, also known as swing hydraulic motor, usually has two types a single blade and double blade. The stator block is fixed to the cylinder, while the vanes and rotor are connected together. According to the oil inlet direction, the vanes will drive the rotor to swing back and forth.

The characteristics of the swing hydraulic cylinder: The swing cylinder has a compact structure and a large output torque, but it is difficult to seal. Generally, it is only used for reciprocating swing, indexing, or intermittent motion in low and medium-pressure systems.

3. Piston hydraulic cylinder

1. Double rod piston hydraulic cylinder. Double rod piston hydraulic cylinders have rods extending from both sides of the piston. When the diameters of the piston rods on both sides are the same, and the oil supply pressure and flow rate are unchanged, the movement speed and thrust F of the piston (or cylinder) in both directions are equal.

2. The single piston rod hydraulic cylinder only has a piston rod at one end. One end of the hydraulic cylinder has a piston rod protruding, and there is no piston rod protruding at the other end. The inlet and outlet oil ports at both ends can pass pressure oil or return oil to realize bidirectional movement, so it is called a double-acting cylinder.

4. Plunger hydraulic cylinder

Introduction of plunger-type hydraulic cylinder: The inner hole of the piston cylinder requires high precision. When the stroke is long, it is difficult to process. At this time, the plunger cylinder should be used. The plunger cylinder can only be made into a single-acting cylinder, and the return stroke is realized by external force or its own weight.

Plunger hydraulic cylinder features: The plunger and the inner wall of the cylinder do not contact, so the inner hole of the cylinder does not need to be finished, with good manufacturability and low cost. In addition, the plunger cylinder has a simple structure and is convenient to manufacture, and is often used in long-stroke machine tools, such as gantry planers, guide rail grinding, and large-scale broaching machines.

5. Combined hydraulic cylinder

1. Booster cylinder - A booster cylinder is also known as a booster, which can convert the input low-pressure oil into high-pressure oil for the high-pressure branch in the hydraulic system;

2. Rack piston cylinder - The rack piston cylinder consists of a double piston cylinder with a rack rod and a rack and pinion mechanism. The reciprocating motion of the piston is transformed into the reciprocating rotation of the pinion shaft through the rack and pinion mechanism, which is mostly used in indexing or indexing mechanisms such as automatic lines and combined machine tools;

3. Multi-stage cylinder - Multi-stage cylinder, also known as a telescopic cylinder, is composed of two or more stages of piston cylinders. Multi-stage cylinders are suitable for construction machinery and other traveling machinery, such as crane telescopic boom hydraulic cylinders, dump truck lifting hydraulic cylinders, etc. are multi-stage cylinders.
