This is an oxygen pump component for fish tanks in pump-valve systems, a specialized Specialty Device Components and Equipment-Specific Fittings designed for aquatic oxygenation applications. As a key part of small-scale fluid control systems, it works in tandem with Sealed Fluid Transfer Pumps (adapted for air) and Mini Sealed Valves to ensure stable oxygen supply for fish tanks. It features a small "stepped" shape with a raised cylindrical head, matched with a bottom disk, and usually has a through-hole in the middle (for air flow passage). Its overall compact and delicate structure fits the tight cavity space of the oxygen pump, facilitating installation and fixation; the surface is smooth, with subtle annular grooves and convex points—these structures are used to enhance sealing or fit with other internal components of the pump, ensuring installation stability and air flow control accuracy. This design aligns with the functional precision requirements of Custom Equipment Parts and Niche Machinery Accessories for specialized aquatic equipment.
Product Features
1. Functions
1)Air Flow Control: As a critical component of the oxygen pump’s air circuit, it controls the "on-off" rhythm of air flow through its own elastic deformation. During the operation of the oxygen pump, it cooperates with electromagnetic components to achieve intermittent air intake and exhaust, continuously delivering a stable pulsed oxygen flow to the fish tank and simulating a natural water flow oxygen dissolution environment. This control function complements the air delivery accuracy of Sealed Diaphragm Pumps (commonly used in small oxygen pumps) and Sealed Fluid Direction Control Valves in low-pressure air systems.
2)Sealing and Leakage Prevention: It fits tightly with the air circuit cavity of the oxygen pump to block gas leakage, maintaining stable air pressure inside the pump. This ensures efficient delivery of oxygen to the fish tank, avoiding reduced oxygenation effects due to air leakage and ensuring sufficient oxygen for fish. This sealing performance meets the strict leak-proof standards of Specialized Equipment Accessories and auxiliary components for aquatic oxygenation systems.
2. Required Characteristics
1)High Air Tightness: It must achieve precise sealing under the pressure environment of the oxygen pump (generally low pressure to normal pressure), with extremely low gas leakage. Poor air tightness will significantly reduce the oxygenation capacity of the oxygen pump, or even make it unable to effectively supplement oxygen to the fish tank. This air tightness requirement is consistent with the performance standards of Equipment-Specific Fittings for low-pressure air systems.
2)Water Resistance and Anti-Aging: In long-term contact with water (the oxygen pump comes into contact with water vapor during operation), it must be water-resistant without swelling or deformation; at the same time, it must resist aging in humid environments. After long-term use (1–2 year cycle), its elasticity and sealing performance should not decline significantly, ensuring stable operation of the oxygen pump. This durability complies with the environmental adaptability standards of Custom Equipment Parts for aquatic environments.
3)Elasticity and Toughness: It must have good elasticity to be easily snapped into the pump body during installation and control air flow through elastic deformation during operation; it should also have toughness to avoid breakage. Even under long-term air flow impact and mechanical vibration, it can maintain its shape and function. This mechanical property aligns with the functional demands of Niche Machinery Accessories for small-scale, dynamic air control.
4)Chemical Stability: In contact with fish tank water (which may contain fish medicine, minerals, etc.), it must have stable chemical properties, not react with substances in the water, and not release harmful substances to contaminate the water quality—ensuring the safety of the fish’s living environment. This stability meets the material safety standards of Specialty Device Components for aquatic applications.
5)Precise Dimensions: It must have strict dimensional tolerances (e.g., within ±0.1mm for key dimensions) to fit precisely with the oxygen pump cavity and other components. Large dimensional deviations can easily lead to difficult installation and sealing failure, directly affecting the oxygenation effect. This precision is consistent with the manufacturing standards of Specialized Equipment Accessories for small-scale pump-valve systems.
