What is the importance of the measurement accuracy of the water purifier pressure gauge for water purifier performance monitoring

In modern water treatment, water purifiers have become essential equipment for ensuring household drinking water safety. The performance of their core components directly determines the quality of the water they produce and the lifespan of the equipment. The water purifier pressure gauge, a seemingly simple accessory, is crucial for effectively monitoring water purifier performance due to its accuracy.

Pressure Gauge Accuracy and Filter Life Management

Water purifiers typically consist of multiple filter cartridges, including PP cotton, activated carbon, and RO membranes. Each filter stage has a specific service life. A pressure gauge provides real-time information on pressure changes as water flows through the filter cartridges. When a filter cartridge, particularly the pre-filter PP cotton and activated carbon filter, becomes clogged due to trapped impurities, the pressure differential between the filter cartridge and the pre-filter increases. A high-precision pressure gauge can keenly detect these subtle pressure fluctuations, providing users with an accurate warning of filter clogging.

For example, a pressure gauge with an accuracy of 1% FS (Full Scale) can accurately display even the smallest fluctuations in pressure. When the pressure begins to rise slowly and continuously, it can be inferred that the pre-filter cartridge is nearing saturation and needs to be replaced. Conversely, if the pressure gauge has low accuracy, its readings may be significantly inaccurate, preventing users from promptly detecting filter clogs. This can not only affect water flow and quality, but may also cause irreversible damage to the subsequent RO membrane. This is because prolonged high-pressure water flow on the membrane surface accelerates scaling and failure. Therefore, a high-precision pressure gauge is a prerequisite for accurate filter life management.

Pressure Gauge Accuracy and RO Membrane Health Diagnosis

The RO membrane is the core of a water purifier, and its performance directly determines the water quality of the purifier. The RO membrane operates by forcing water molecules through the semipermeable membrane under high pressure, while retaining pollutants and ions. The ideal operating pressure of an RO membrane is typically between 60 and 90 PSI (pounds per square inch). The accuracy of the pressure gauge directly affects the assessment of the RO membrane's operating condition.

A high-precision pressure gauge provides stable pressure readings, helping technicians or users accurately determine whether the RO membrane's operating pressure is within the ideal range. Excessively high pressure readings may indicate severe scaling or clogging on the membrane surface, hindering water flow. Low readings may indicate decreased booster pump efficiency or a leak in the water inlet line. Any minor pressure anomaly could signal deteriorating RO membrane health.

In addition, during water purifier maintenance, technicians assess RO membrane performance by comparing the pressure difference before and after the membrane. Excessive pressure differences may indicate the membrane needs to be cleaned or replaced. An inaccurate pressure gauge can lead to uncertainty in obtaining these critical readings, compromising diagnostic accuracy. This can result in unnecessary membrane replacements, increased maintenance costs, or misdiagnosis leading to delayed resolution and ultimately, complete membrane failure. Therefore, a high-precision pressure gauge is a professional tool for RO membrane health diagnosis and performance assessment.

Pressure Gauge Accuracy and System Troubleshooting

In addition to monitoring filter element and RO membrane performance, pressure gauges also play an indispensable role in troubleshooting the entire water purification system. Water purifier system failures can stem from a variety of factors, including booster pump failure, line leaks, and clogged solenoid valves.

For example, if the booster pump is operating normally but the pressure gauge reading is significantly lower than normal operating pressure, this may indicate a leak in the water inlet pipe or deterioration in the booster pump's performance. Conversely, if the pressure gauge reading slowly decreases instead of returning to zero after the booster pump stops operating, this could indicate an air lock or pipe blockage within the system. A high-precision pressure gauge can clearly display these subtle pressure fluctuations, helping technicians quickly and accurately locate the fault.

Pressure gauge accuracy is particularly important in commercial water purification equipment. Commercial customers typically have higher requirements for water output and stability. A high-precision pressure gauge can help businesses monitor equipment operating status in real time, predict potential failure risks, and develop preventative maintenance plans, thereby minimizing production interruptions and financial losses caused by equipment failure.
