Product Features
1. Functions
1)Liquid Transfer and Metering: In household coffee machines, the solenoid pump diaphragm cooperates with the solenoid pump to precisely control the extraction and pressurization of water flow, delivering water to the coffee grounds area in a set volume to produce coffee with stable concentration and taste. In some household water purification equipment, it regulates water flow rate, ensuring filtered water enters the water storage tank or water terminal at an appropriate speed. This metering function complements the precise control capabilities of Sealed Fluid Transfer Pump in small household systems.
2)Gas Transfer and Pressure Regulation: In some household equipment with air pumps (such as small inflators), the solenoid pump diaphragm enables gas suction and discharge. It changes the pump cavity volume through reciprocating movement to provide stable air pressure for the equipment, which is used to inflate balloons, air cushions, etc. Meanwhile, in some air purification equipment, it adjusts the size and pressure of air flow to ensure purification efficiency. This pressure regulation role supports the functional stability of Sealed Fluid Direction Control Valve in household gas systems.
3)Isolation and Sealing: It isolates the transported liquid or gas from other components of the solenoid pump, preventing the medium from corroding or contaminating the pump body and ensuring the normal operation and service life of the equipment. For example, in some household liquid medicine dispensers, the diaphragm ensures that the medicine does not leak into the mechanical parts of the pump, maintaining the hygiene and accuracy of the equipment. This isolation performance meets the protective standards of Sealing Elements for Valves in household sanitary-related fluid systems.
2. Required Characteristics
1)High Elasticity and Flexibility: Since it needs to perform frequent reciprocating deformation driven by the solenoid pump, good elasticity and flexibility ensure the diaphragm resists fatigue and damage during long-term use, and can quickly return to its original shape after deformation to maintain the pump’s normal working cycle. For instance, in coffee machines, the diaphragm may undergo multiple expansion and contraction movements per minute; poor elasticity will lead to premature damage of the diaphragm. This mechanical property is comparable to the elastic requirements of Diaphragms & Sealing Gaskets in dynamic household applications.
2)Excellent Sealing Performance: The joint between the diaphragm and the pump cavity must have outstanding sealing capabilities to prevent liquid or gas leakage. Any leakage may cause abnormal equipment functions, such as unstable water output from coffee machines or insufficient air pressure in inflators. This sealing reliability complies with the leak-proof standards of Pressure Seal Components and Fluid-Tight Diaphragms in household equipment.
3)Chemical Stability: It must withstand various common media in household equipment, such as acidic substances in coffee liquid, minerals in tap water, and chemical components in medicines. It should not react chemically with the media or leach harmful substances to contaminate the media. This stability meets the material safety standards of Sealing Elements for Valves in household scenarios involving food or medicine contact.
4)Temperature Resistance: The operating temperature of household equipment may vary (e.g., coffee machines generate heat during operation). The solenoid pump diaphragm must maintain stable physical and chemical properties within a certain temperature range (e.g., 0℃ - 80℃), without softening or deforming at high temperatures, or becoming brittle and losing elasticity at low temperatures. This temperature adaptability aligns with the environmental resilience requirements of Gasket & Membrane Assemblies in household working conditions.
5)Long Service Life and Reliability: As a component of household equipment, it must have a long service life and high reliability, reducing the frequency of equipment maintenance and replacement, and lowering users’ usage costs and maintenance troubles. This durability meets the practical application needs of Sealed Diaphragm Pump supporting components in long-term household use.
