Product Details
The refrigerator compressor valve plate, acting as the "heart valve" of the refrigeration cycle, directly impacts system efficiency and stability. With the iteration of refrigeration technology, valve plate structures are constantly innovating, evolving from traditional flat valve plates to multi-porous array valve plates using laser cutting technology, increasing gas flow efficiency by over 30%. The application of new composite materials, such as ceramic-coated valve plates, significantly enhances wear resistance and corrosion resistance, maintaining precise airtightness even under extreme conditions.
In practical use, various malfunctions may occur in the valve plate. Valve plate wear is a common problem; long-term high-frequency opening and closing causes the edges of the valve plate to thin and deform, leading to decreased suction and exhaust efficiency and slow refrigerator cooling. Aging of the sealing gasket will cause refrigerant leakage, increasing energy consumption and polluting the environment. In addition, carbon deposits or impurities blocking the valve plate surface will interfere with the normal suction and exhaust rhythm, producing abnormal noise.
Regular maintenance is crucial to address these issues. Regularly clean the dust inside the compressor to prevent impurities from entering the valve plate area; use pressure testing and noise detection to promptly identify signs of valve plate performance degradation. For commercial refrigerators that frequently start and stop, professional inspection and replacement of worn seals are recommended every six months to ensure the valve plate is always in optimal working condition. Scientific maintenance not only extends the service life of the valve plate but also improves the operating efficiency of the entire refrigeration system, reducing equipment operating costs.
