This is an medical sealing rubber piston. It’s made for spray hydrating devices in the healthcare industry. It’s a key sealing and functional part. It meets the performance standards of Pump Valves and Sealing Parts for Testing Equipment and Detection Device Seals.It has an overall hemispherical-like structure. This structure has a certain curvature. Its edges are thin, soft, and elastic. This lets it change shape when pressed. The central area has a protrusion and an opening. These are for connection or positioning. They make it easy to fit with parts of the spray hydrating device. Things like the piston and pump body.It’s made of high-quality elastic materials. These materials meet the basic requirements of medical silicone seal. It gives reliable pressure control and sealing support to spray hydrating devices. It also helps keep the functional integrity of Testing Instrument Sealing Parts.
Product Features
1.Functions
1)Pressure Chamber Formation:It’s installed inside the pump body of the spray hydrating device. It works with other parts to form a closed pressure chamber. When the piston or push rod moves, the elastic cup changes shape along with it. This changes the volume of the pressure chamber. When the volume gets bigger, the pressure inside the chamber gets lower. This pulls water from the water tank into the pressure chamber. When the volume gets smaller, the pressure inside the chamber gets higher. This squeezes water through the nozzle to make a spray. This pressure regulation function is as good as the fluid control performance of Testing Pump Valves in precision fluid systems.
2)Sealing and Leak Prevention:It uses its own elasticity. It fits tightly against the inner wall of the pump body. This creates a sealing effect. It stops water from leaking out of the pressure chamber. It also makes sure pressure is built up and kept effectively. This lets the spray hydrating device spray uniform water mist stably and continuously. Its sealing reliability meets the strict standards of Medical Device Seals and Sterile Medical Seals for holding fluids.
2. Required Characteristics
1)Excellent Elasticity and Flexibility:It must be able to change shape elastically many times. After changing shape, it must bounce back to its original form quickly. This makes sure its sealing performance doesn’t get worse during long-term use. At the same time, it must fit different pressure changes. This keeps the pump body of the spray hydrating device working normally. This mechanical performance is as good as that of high-quality Medical Grade Silicone Seals. It meets the dynamic sealing requirements of Lab Equipment Gaskets.
2)Chemical Stability:It must stand being worn away by water. It also must stand components that may be added to water. Things like moisturizers and fragrances. It can’t have chemical reactions that cause problems. Like swelling, getting worse, or hardening. This makes sure the elastic cup lasts a long time. It also makes sure the spray hydrating device is safe to use. This stability meets the material standards of Pump Valves and Sealing Parts for Testing Equipment that touch daily-use fluids.
3)Wear Resistance:It moves relative to the pump body parts. During this movement, it must have a certain degree of wear resistance. This reduces wear caused by friction. It lowers how often you need to replace it. It also makes the spray hydrating device more reliable overall. This durability matches the service life requirements of Testing Instrument Sealing Parts in dynamic working scenarios.
4)Hygiene:The material itself must stop microorganisms from growing. Things like bacteria and mold. This makes cleaning and maintenance easy. This ensures the water mist sprayed by the device is clean and hygienic. It won’t cause bad effects on the skin. This hygienic attribute meets the safety standards of Sterile Medical Seals for medical accessories that touch the skin.
5)Dimensional Adaptability:It must have precise dimensions. It must fit tightly with the installation position of the spray hydrating device’s pump body. This avoids water leakage from big gaps after installation. It also stops dimensional deviations from getting in the way of the pump body’s normal operation. This dimensional precision is the same as the assembly requirements of Detection Device Seals and Medical Vial Cap Seals for tight fitting.
