1. What components should be checked if the water pump of the pure water machine does not produce water after starting?
If the water pump of the pure water machine does not produce water after starting, the core components should be checked in the following order.
1. Water source and inlet system • Inlet valve: Confirm whether it is fully opened and check if the valve is damaged • Pre filter element: Observe whether the PP cotton/activated carbon filter element is blocked (normal pressure difference should be less than 0.1MPa) • Inlet pressure: Use a pressure gauge to detect the standard value of 0.1-0.4MPa. If it is lower than 0.1MPa, a booster pump should be installed. 2. Water pump components • Power input: Use a multimeter to detect the water pump voltage. For 24V/36V models, ensure that the voltage fluctuation does not exceed ± 10% • Rotor jamming: Manually rotate the motor shaft after power failure, Non resistance rotation • Pressure switch: Test the continuity of the contact, and the shutdown pressure value is usually set at 0.2-0.25MPa3 Pipeline and sealing • Quick connector: Check if all interfaces are fully inserted and if the O-ring is damaged • Check valve: located at the water pump outlet, reverse pressure test for leakage (standard pressure>0.6MPa) • Membrane housing sealing ring: Open the RO membrane housing to check if the sealing rings at both ends have deformed and if there are any foreign objects on the sealing surface. 4 Key sensors • Low voltage switch: Short circuit test to determine if protection is triggered (positive Mu Bu constant closing resistance<1 Ω) • High voltage switch: Simulate full water state of the Zen hood to test if disconnection is timely (action value is usually 0
2. How to determine whether the filter element of the ultrapure water machine needs to be replaced?
To determine whether the filter element of the ultrapure water machine needs to be replaced, it is mainly based on five core indicators: water quality monitoring, equipment performance, usage time, and sensory changes.
. 1. Observing water quality data (TDS value): Ultra pure water machines are usually equipped with online water quality monitoring systems, and an increase in TDS value (total dissolved solids) is the most direct signal of a decrease in filter performance. When the TDS value of the effluent exceeds the normal range of the instrument (such as significantly increasing from the usual 1-5 µ S/cm), the chain pin means that the filter elements ability to intercept impurities is insufficient and needs to be replaced. If it cannot be restored after cleaning, the filter element must be replaced. 3. Calculate the usage time of the filter element. Following the official recommendation of the filter element replacement cycle is the basic guarantee, dear brother. The lifespan of different filter elements varies greatly: • PP cotton filter element: mainly filters large particle impurities such as sediment and rust, with a shorter lifespan, usually 3-6 months.
