Unidirectional Motion: Motion in a single direction is achieved solely through hydraulic pressure; the return stroke relies on gravity, spring force, or other external forces.
Structural Components: Primarily composed of a cylinder barrel, plunger, guide sleeve, seals, and gland. The plunger does not make contact with the inner wall of the cylinder barrel; instead, motion precision is ensured by the guide sleeve.
Excellent Manufacturability and Low Cost: Since the inner wall of the cylinder barrel does not require precision machining, this design is well-suited for long-stroke applications.
Output Characteristics: Thrust and speed are determined by the pressure-bearing surface area of the plunger's end face; as the plunger remains under constant compressive stress during operation, it must possess sufficient rigidity.
Installation Requirements: Due to the significant self-weight of the plunger, vertical installation is recommended to prevent horizontal positioning from causing uneven, unilateral wear on the seals.
Achieving Bidirectional Motion:** Reciprocating motion is typically achieved by arranging two plunger cylinders in an opposing configuration or by integrating them with other mechanical mechanisms.
