Abstract

The invention discloses a reverse osmosis pure water machine controller for intelligently detecting and adjusting the recovery rate, which is characterized in that: a core control part is a singlechip; a data line of a display screen is connected with the singlechip; inlet water and pure water flow signals are connected with the singlechip; inlet water and pure water conductivity detecting probes are connected with the singlechip; the conductivity detecting probes and a temperature thermistor are connected with an analogue to digital conversion circuit; a concentrated water regulating valve is controlled by the singlechip, and is an analog quantity regulating valve; in an operation control method, a working program is compiled by adopting assembler language, and hardware circuits are controlled by the singlechip; and a removal rate calculation and alarm function and a recovery rate calculation and adjustment function are included in control functions. The reverse osmosis pure water machine controller has the advantages that: by detecting and intelligently controlling the flow and conductivity of the inlet water and pure water, the concentrated water regulating valve is automatically adjusted to make the recovery rate of the reverse osmosis pure water machine always positioned in the most reasonable state so as to fully utilize water resources.

Description

technical field [0001] The invention relates to measurement and control technology, in particular to a reverse osmosis pure water machine controller for intelligent detection and adjustment of recovery rate. Background technique [0002] The reverse osmosis pure water machine uses the separation function of the semipermeable reverse osmosis membrane to pass the water through the reverse osmosis membrane under a certain pressure, and some water molecules flow out through the reverse osmosis membrane, which is pure water. Impurities in water (such as inorganic salts, organic matter, microorganisms, etc.) are relatively concentrated and flow out, which is technically called concentrated water. Since the reverse osmosis membrane needs sufficient pressure to work, in general, a throttling device is installed at the concentrated water outlet to ensure sufficient osmotic pressure for the reverse osmosis membrane by controlling the concentrated water flow. At the same time, in orde...
