The invention discloses an automatic ultrafiltration water purification flushing system which comprises a first ultrafiltration membrane, a second ultrafiltration membrane, a first solenoid valve, a second solenoid valve, a third solenoid valve and a flow meter, wherein the first solenoid valve and the second solenoid valve are connected to a first pipeline, and running water enters the first pipeline; the first solenoid valve is connected with the first ultrafiltration membrane, and the second solenoid valve is connected with the second ultrafiltration membrane; first outlet ends of the firstultrafiltration membrane and the second ultrafiltration membrane are connected with the second pipeline in a parallel manner; the second pipeline is connected to the third solenoid valve, and the third solenoid valve is connected with the third pipeline; second outlet ends of the first ultrafiltration membrane and the second ultrafiltration membrane are connected with a fourth pipeline in a parallel manner; the fourth pipeline is connected with the flow meter; and the flow meter is connected with a water valve by a fifth pipeline. The automatic ultrafiltration water purification flushing system disclosed by the invention has main beneficial effects that with the adoption of multiple flushing methods, fixed-point flushing is realized, using experience of a user is not influenced, and a flushing effect is achieved; and the service life of the ultrafiltration membrane is scientifically and reasonably prolonged, the service time of the material is prolonged and the usage rate of the raw materials is increased, and resources are saved.
Description
Technical field: [0001] The invention relates to the technical field of ultrafiltration water purifiers, and more specifically relates to an ultrafiltration water purification automatic flushing system and a control method. Background technique: [0002] Ultrafiltration water purifiers on the market usually use regular flushing for n hours (for example: 24 hours) after the machine is powered on, or the machine is powered on for flushing. The flow rate at the water outlet of the ultrafiltration membrane was not detected, or fixed-point flushing. The flushing time and frequency of the ultrafiltration membrane directly affect the service life of the ultrafiltration membrane, and an effective flushing method with a large flow rate will effectively ensure the service life of the ultrafiltration membrane. Invention content: [0003] What the present invention aims to solve is the technical problem that the ultrafiltration flushing method is unreasonable, which causes the servic...
