Detailed description of the invention
Be described further with regard to technical scheme of the present invention below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention proposes a kind of reverse osmosis membrane purifier.
See figures.1.and.2, Fig. 1 is the water route schematic diagram of reverse osmosis membrane purifier one embodiment of the present invention; Fig. 2 is the circuit diagram of reverse osmosis membrane purifier one embodiment of the present invention.
In embodiments of the present invention, shown in Figure 1, this reverse osmosis membrane purifier comprises the booster pump 10, pressure sensor 20 and the reverse osmosis membrane assembly 30 that connect successively, reverse osmosis membrane assembly 30 is provided with the first reverse osmosis membrane water inlet 31, first reverse osmosis membrane wastewater outlet 32 and the second reverse osmosis membrane pure water inlet 33, wherein, pressure sensor 20 is arranged at the first reverse osmosis membrane water inlet 31, for measuring the current pressure values of the first reverse osmosis membrane water inlet 31 in real time; Second reverse osmosis membrane wastewater outlet 33 is connected with electrically-controlled valve 40.
Shown in Figure 2, this reverse osmosis membrane purifier also comprises controller 50, controller 50 is electrically connected electrically-controlled valve 40 and pressure sensor 20, controller 50 controls the restriction bore of electrically-controlled valve 40 according to the current pressure values that pressure sensor 20 records, and the current pressure values recorded to make pressure sensor 20 is in preset pressure value range.
The present invention is provided with pressure sensor 20 at the first reverse osmosis membrane water inlet 31, second reverse osmosis membrane wastewater outlet 33 is provided with electrically-controlled valve 40, and electrically-controlled valve 40 is all connected with controller 50 with pressure sensor 20, wherein pressure sensor 20 detects the pressure of reverse osmosis membrane cephacoria at the first reverse osmosis membrane water inlet 31 place, and the pressure signal source detected is fed back to controller 50, controller 50 then adjusts according to the restriction bore of signal feedback to electrically-controlled valve 40, under the prerequisite of booster pump 10 constant power, the restriction bore reducing electrically-controlled valve 40 can improve the hydraulic pressure in reverse osmosis membrane purifier water route, the restriction bore expanding electrically-controlled valve 40 then can reduce the hydraulic pressure in reverse osmosis membrane purifier water route, therefore, when causing the change of hydraulic pressure when the change because of water quality in water route, pressure sensor 20 will feed back to controller 50 in time, controller 50 can adjust according to the restriction bore of signal feedback to electrically-controlled valve 40, enter in preset pressure value range to make the hydraulic pressure in reverse osmosis membrane purifier water route, thus pressure before stablizing the film of reverse osmosis membrane, be conducive to the filter effect of stable reverse osmosis membrane, to reach the filter effect of expection.
With reference to shown in Fig. 3, Fig. 3 is the circuit diagram of another embodiment of reverse osmosis membrane purifier of the present invention.
