III. the system function

3.1, the salt content of less than or equal 40000ppm waters into compliance with GB5749-2006 standard fresh drinking water, the salt content of the water is less than 700ppm;

3.2, the filter uses three-way valve control can be easily and quickly complete the backwash, rinse and filter operations

3.3, the high-pressure pump water overpressure protection, when high-pressure pump outlet pressure exceeds 6.5MPa (adjustable) equipment automatically shut down concurrent sound and light alarm;

3.4, high-pressure pump is insufficient water pressure undervoltage protection, when pretreated water shortage caused by the high pressure pump inlet pressure is below 0.05MPa (can be set), the device automatically shut down concurrent sound and light alarms;

3.5 with cleaning water tanks, reverse osmosis membrane can be chemically cleaned and perfusion protective solution;

3.6, the process parameters (Concentrated water flow, product water flow rate, operating pressure, producing water conductivity, etc.) in situ monitoring function;

IV. Reliability & maintainability

Mechanical parts usually trouble-free working hours: MTBF≥10000h;

Electric control part of the average trouble-free working hoursMTBF≥5000h.

Maintenance of the device to meet GJB3683-87 "Maintainability versatility Specifications" in the application of common parts Maintenance requirements, specified in the maintenance space can disassemble and repair the main components, mean time to repair MTTR device ≤ 5h.
