In order to facilitate a better understanding of the reverse osmosis water purification system described above, a detailed explanation is given below with reference to specific examples.
The reverse osmosis filter element of the reverse osmosis water purifier is influenced by various characteristics, the water production quantity and the temperature change have a direct relation, and generally, the water production quantity of the reverse osmosis water purifier is reduced along with the reduction of the temperature. The main reason is that the viscosity of water is affected by temperature, the lower the temperature, the greater the viscosity of water. Under normal conditions, the water yield of the water purifier can be reduced by about 2.5% when the temperature is reduced by 1 ℃. At present, the water purification mode of the existing reverse osmosis water purifier is generally that tap water which is not treated is directly introduced, so that the water yield of the reverse osmosis water purifier is low in a low-temperature environment.
In order to optimize the water outlet experience of the reverse osmosis water purification system, the method is realized by the following technical scheme:
the structure of the reverse osmosis water purification system is shown in fig. 1 and fig. 2, a controller 302 processes detected input signals, then the detected input signals are matched with correspondingly designed control logics, the duty ratio of a duty ratio adjusting device 303 is adjusted, so that the 36V voltage input by a power adapter 301 is converted into different output voltages, the adjustment of the booster pump 5 in the voltage range of 18V-36V is realized, the higher the voltage is, the higher the rotating speed of the booster pump 5 is, the higher the output flow rate is, and the change of the input voltage of the booster pump 5 is changed, so that the change of the pure water flow rate of the reverse osmosis water purification system under different use conditions is realized.
The temperature detection device 4 is arranged at the water inlet of the reverse osmosis system and is used for detecting the water temperature change in the reverse osmosis system; the pressure detection device 6 is arranged in front of the reverse osmosis filter element and can detect the pressure change in front of the reverse osmosis filter element membrane; the flow meter 10 is provided at the pure water port position and can detect the change in the pure water flow rate. Through temperature, pressure and the flow variation among the detection reverse osmosis system, judge the pure water flow that different conditions lead to and reduce, adjust the input voltage of booster pump 5 through controlling means 3 and change the rotational speed and the output flow of booster pump 5, realize the pressure regulation before the reverse osmosis membrane, and then make the stability of the pure water flow of reverse osmosis water purification system under different service conditions.
Further, the voltage regulation is calculated by:
operating target pressure value P2 ═ P1/TCF
Wherein TCF is the temperature correction coefficient of the diaphragm, and P1 is the current system pressure before the diaphragm.
Voltage regulation value X ═ K1K2P2+ K2C1+ C2-C3)/K3
K1, C1 is the pressure-flow rate change constant of the standard pump (under the same voltage);
k2, C2 is the voltage-flow rate change constant of the standard pump (at the same pressure);
k3, C3 is the voltage-pressure variation constant of the standard pump (at the same flow rate);
the value of X is between 12 and 36V.
Further, if attenuation of the RO (Reverse Osmosis) membrane is considered, then
Operating target pressure value P2 ═ (P1 × Q1)/(Q2 × TCF)
Wherein TCF is the temperature correction coefficient of the diaphragm, and P1 is the current system pressure before the diaphragm. Q1 is the flow at 25 ℃ of the initial state, and Q2 is the current system flow.
Voltage regulation value X ═ K1K2P2+ K2C1+ C2-C3)/K3
K1, C1 is the pressure-flow rate change constant of the standard pump (under the same voltage);
k2, C2 is the voltage-flow rate change constant of the standard pump (at the same pressure);
k3, C3 is the voltage-pressure variation constant of the standard pump (at the same flow rate);
the value of X is between 12 and 36V.
If only the pure water flow fluctuation caused by the water temperature change is considered, the temperature adjusting range needs to be set, for example, the temperature is set to be lower than 20 ℃ to start adjusting, the temperature detecting device 4 detects the change of the temperature of the raw water entering the reverse osmosis system, the pressure detecting device 6 detects the pressure change before the membrane, the control device 3 obtains an operation target pressure value P2 which is P1/TCF according to the detected condition change, and then the input voltage of the booster pump 5 is adjusted through the formula X which is (K1K2P2+ K2C1+ C2-C3)/K3. Pure water flow reduction due to water temperature: the temperature of the raw water entering the reverse osmosis system is detected by the temperature detection device 4 and input to the controller 302. When the temperature is more than or equal to 20 ℃, the working voltage of the booster pump 5 is 18V; when the temperature is 15-20 ℃, the pure water flow of the reverse osmosis water purification system is reduced to a certain extent, the output flow of the booster pump 5 under the same pressure is increased by adjusting the working voltage of the booster pump 5 to be 20V, and the reduction of the pure water flow in the temperature range is compensated; the temperature is 10-15 ℃, and the working voltage of the booster pump 5 is adjusted to 22V; the temperature is 5-10 ℃, and the working voltage of the booster pump is adjusted to 24V.
Further, considering the pure water flow rate attenuation caused by the RO cartridge attenuation, it is necessary to determine the pure water flow rate Q1 at a temperature of 25 ℃ according to actual conditions, start adjustment after the flow meter 10 detects that the pure water flow rate is reduced by 100ml or more from the pure water flow rate Q1 at a temperature of 25 ℃, the temperature detection device 4 detects a change in the temperature of the raw water entering the reverse osmosis system, the pressure detection device 6 detects a change in the pre-membrane pressure, the control device 3 obtains an operation target pressure value P2 (P1Q 1)/(Q2 TCF) according to the detected condition change, and adjusts the input voltage of the booster pump 5 by using a formula X (K1K2P2+ K2C1+ C2-C3)/K3). When the flowmeter 10 detects that the pure water flow rate is attenuated to be within the range of 50 ml-100 ml relative to the pure water flow rate Q1 at 25 ℃ in the initial state, the input voltage of the booster pump 5 is adjusted to be 20V, and the change of the pure water flow rate caused by the attenuation of the reverse osmosis membrane is compensated; when the temperature is higher than 20 ℃, the pure water flow rate is attenuated within the range of 100ml to 200 ml; the input voltage of the booster pump 5 is adjusted to be 22V; when the temperature is higher than 20 ℃ and the pure water flow rate is attenuated to be more than or equal to 200ml, the input voltage of the booster pump 5 is adjusted to be 24V.
The reverse osmosis water purification system with the four-stage filtration can monitor the water temperature change, the pure water flow change and the pressure change in front of the reverse osmosis membrane of the reverse osmosis water purification system in real time, and judges different using conditions of the reverse osmosis water purification system through the control device 3. The pure water flow of the reverse osmosis system with low water temperature in winter is reduced, the control device 3 automatically adjusts the voltage of the booster pump 5 to increase the rotating speed of the booster pump 5 by detecting the water temperature change and the pure water flow change, and further increases the pressure in front of the reverse osmosis membrane to increase the pure water flow of the reverse osmosis water purification system under the condition of low water temperature. The reverse osmosis water purification system uses the in-process because reverse osmosis membrane's decay leads to pure water flow to reduce, detects this kind of change, improves the rotational speed of booster pump through the voltage that improves booster pump 5, improves the pressure in front of the reverse osmosis membrane, and then reduces the pure water flow that leads to because reverse osmosis membrane decay and reduces.
