Problems solved by technology

The use of high-voltage switches and low-voltage switches will occupy the space in the RO machine, increase assembly man-hours, increase product costs, and reduce production efficiency. Moreover, high-voltage switches and low-voltage switches are prone to failure, which will cause frequent startup or disconnection of the booster pump. Negative effects caused by booster pump and RO machine

Abstract

The invention provides a RO water treating system and a control method thereof. The system comprises a water treating module, a control module and a booster pump, which are arranged between a raw water inlet pipe and a water purifying faucet, and the system further comprises a pressure sensor and a one-way valve; the water treating module comprises a RO filter element, the booster bump is connected with a water inlet end of the RO filter element, the pressure sensor is arranged between the booster bump and the water purifying faucet, the one-way valve is arranged between the raw water inlet pipe and the pressure sensor, and the pressure sensor is used for detecting pressure between the one-way valve and the water purifying faucet; a control module receives a signal of the pressure sensor and controls on-off of the RO water treating system. According to the system, an original high-tension switch and a low-tension switch are canceled, one pressure sensor completes the control on the whole RO water treating system, the inner space of a RO machine is saved, the production cost of the RO machine is reduced, the structure is simple, the assembly is convenient and quick, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an RO water treatment system and a control method thereof. Background technique [0002] The pure water machine is a kind of water purification equipment that uses multi-stage filter elements for water purification treatment. The treatment mostly uses physical methods such as filtration, adsorption, and reverse osmosis without adding chemical substances. According to the water purification accuracy of the pure water machine, it can be divided into two types: the drinking type pure water machine and the laboratory pure water machine that can meet the laboratory pure water quality requirements. Most water purifiers adopt advanced ultra-low pressure reverse osmosis technology and accessories, with high-quality water production, safe operation, stable and reliable operation, simple operation, small footprint, and effective removal of calcium, magnesium, bacteria, organic matt...
