This is a tower-shaped 6-port piston body for air pumps of massagers in pump-valve systems, a specialized component of Precision Piston Assemblies and Multi-Port Piston Units designed for low-pressure pneumatic applications. It works in tandem with Sealed Fluid Transfer Pumps (air pumps) and Mini Sealed Valves to ensure stable air supply for massagers, featuring an approximately circular overall shape with a gear-like convex outline on the edge. There is a large circular through-hole in the center, surrounded by six uniformly distributed ports with tower-shaped protrusions—when viewed from the top, these tower-shaped protrusions taper conically. The piston body has a certain thickness, forming upper and lower surfaces, with the tower-shaped protrusions extending from the lower surface to the upper surface. Its structural design aligns with the functional requirements of Pistons and Hydraulic Piston Components (adapted for pneumatic systems) in compact massager equipment.
Product Features
1. Functions
1)Sealing Function: During the operation of the massager’s air pump, the tower-shaped structure can fit well with corresponding components to seal the air circuit, preventing gas leakage. This ensures the air pump can effectively perform suction and exhaust actions, maintaining stable air pressure inside the pump. This sealing role meets the leak-proof standards of Sealed Fluid Direction Control Valves and auxiliary pneumatic components, critical for maintaining consistent air pressure in massager airbags.
2)Gas Propulsion: With the reciprocating movement of the piston body, the tower-shaped structure can squeeze and push air, realizing the gas transmission function of the air pump. This inflates or deflates the massager’s airbags to achieve the massage effect. This propulsion function complements the air delivery capability of Sealed Diaphragm Pumps (commonly used in small air pumps) and aligns with the operational needs of Reciprocating Pistons in cyclic pneumatic systems.
2. Required Characteristics
1)Excellent Sealing Performance: The material must have good elasticity and flexibility to fit tightly with other components, preventing gas leakage. This elastic property is consistent with the sealing requirements of Hydraulic Piston Components (for pneumatic scenarios) and ensures long-term airtightness of the air circuit.
2)Wear Resistance: During the air pump’s operation, the piston body needs to perform continuous reciprocating movements, generating friction with other components. Thus, it must have good wear resistance to ensure a long service life—meeting the durability standards of Precision Piston Assemblies in high-cycle pneumatic applications.
3)Corrosion Resistance: The massager’s operating environment may involve exposure to moisture; therefore, the piston body material must have a certain degree of corrosion resistance to prevent damage from corrosion. This property complies with the material stability requirements of Multi-Port Piston Units in humid household environments.
4)Appropriate Hardness: The hardness must be moderate—sufficient to prevent deformation during movement, while also enabling good coordination with other components to achieve sealing and gas propulsion functions. This balanced mechanical property aligns with the performance demands of Pistons used in small-scale, low-pressure pneumatic systems like massager air pumps.
