RO machine intelligent water saving system and control method thereof

Abstract

The invention relates to an intelligent water-saving system of an RO (Reverse Osmosis) machine and a control method of the intelligent water-saving system. The control method comprises the following steps of judging whether the water pressure is normal or not after power on, if yes, turning on a first water inlet solenoid valve, turning on a rinsing solenoid valve and rinsing; making water after finishing rinsing until a pressure tank is full, turning on a second water inlet solenoid valve, closing the first water inlet solenoid valve, turning on the rinsing solenoid valve, and rinsing; lowering the pressure to a critical value after the pressure tank gets water normally, judging whether the water pressure is normal or not, if yes, turning on the first water inlet solenoid valve, turning on the rinsing solenoid valve, rinsing, and then stopping the rinsing solenoid valve; collecting data simultaneously with a TDS contact and a temperature contact, and calculating through a chip to determine whether the system needs to be rinsed; if no, making water directly; if yes, turning on the first water inlet solenoid valve, and turning on the rinsing solenoid valve; making water until the pressure tank is full, turning on the second water inlet solenoid valve, closing the first water inlet solenoid valve, meanwhile turning on the rinsing solenoid, rinsing and then stopping the machine. According to the intelligent water-saving system, a water-saving effect is realized, and a way is paved for the machine to become a machine suitable for promotion in the market.

Description

technical field

[0001] The invention relates to the technical field of water saving, and more specifically relates to an intelligent water saving system of an RO machine and a control method thereof. Background technique

[0002] Working characteristics and defects of the traditional RO machine: when purifying water, the concentrated water produced is too much, which is not easy to manage, passive management, and serious waste of water resources (especially the RO membrane decays to the later stage); when the RO membrane decays to 50%, the purified water : Concentrated water = 1:6, such a ratio of concentrated water is unacceptable to consumers, and RO will have to be replaced, and the cost of use for customers will increase, and the value of RO membrane will not be maximized, resulting in waste; the water quality treatment method is single, and there is no combination of raw water The water quality adopts proper water production process management, the working principle is ...
