كيف تقاوم مقاييس الضغط المملوءة بالسوائل الاهتزازات والتداخل النبضي بشكل فعال في قياس الضغط

Liquid filled pressure gauges are specialized instruments designed for harsh working environments, with their liquid-filled design being one of their core advantages. In conditions with pulsation or vibration, ordinary pressure gauges often suffer from pointer jitter or mechanical wear, leading to measurement errors or even equipment damage. Liquid filled pressure gauges can effectively absorb vibration and pulsation, ensuring accurate and stable pressure measurement. Some liquid-filled pressure gauges adopt a dual-scale design. The مقياس ضغط مملوء بالسائل بمقياس مزدوج not only has the anti-vibration and pulsation protection functions of the liquid-filled design, but also provides the convenience of multi-unit readings through a dual-scale display, which significantly improves the flexibility and applicability of pressure measurement.

Working Principle of the Liquid-Filled Design
The interior of a liquid filled pressure gauge is filled with a special liquid (usually glycerin or silicone oil), which has high viscosity and excellent damping properties. When the gauge is subjected to external vibration or pulsating pressure, the liquid absorbs and buffers this energy, reducing the impact on the internal mechanical structure. This damping effect not only protects the pointer and gear mechanism of the gauge but also significantly reduces pointer jitter, ensuring clearer and more stable readings.

Practical Applications of Vibration Resistance
In industrial machinery, compressed air systems, and hydraulic equipment, vibration and pulsation are common issues. For example, during the operation of hydraulic pumps or compressors, high-frequency pulsating pressure is generated within the system, making it difficult for ordinary pressure gauges to accurately reflect the actual pressure values. Liquid filled pressure gauges can effectively filter out these high-frequency pulsations, providing smooth pressure readings. Additionally, in heavy machinery such as stamping machines or injection molding machines, the vibration resistance of liquid filled pressure gauges allows them to operate stably in high-vibration environments for extended periods, reducing the frequency of maintenance and replacement.

Key Role of Pulsation Protection
In systems with pulsating pressure, the liquid-filled design of liquid filled pressure gauges can significantly reduce the interference of pulsation on measurement results. For instance, in the oil and gas industry, fluid flow within pipelines generates intense pulsating pressure, which may cause ordinary pressure gauges to produce inaccurate readings due to severe pointer oscillations. Through the damping effect of the liquid, liquid filled pressure gauges can smooth out pulsating pressure, ensuring accurate and reliable measurement results. This feature is particularly important for pressure monitoring in high-pressure pipelines and storage tanks.

Adaptability to Harsh Working Conditions
The liquid-filled design of liquid filled pressure gauges is not only suitable for environments with vibration and pulsation but also maintains stable performance under extreme temperatures and corrosive media. Stainless steel liquid-filled pressure gauges can withstand corrosive gases or liquids in industries such as chemical, pharmaceutical and food. The thermal stability of the filling liquid ensures reliable operation of the gauge in high or low-temperature environments.

Versatile Installation Options
The liquid-filled design of liquid filled pressure gauges, combined with their versatile installation options (such as center-back, lower, lower-back, and flange mounting), further enhances their applicability. For example, in space-constrained equipment, lower or lower-back mounting saves installation space, while flange mounting provides a more secure fixation in situations requiring high stability. This flexibility allows liquid filled pressure gauges to meet the needs of various industries and equipment.
