Description

technical field [0001] The invention relates to an intelligent control system for a pure water machine. Background technique [0002] At present, with the improvement of people's living standards, people pay more and more attention to the sanitation of drinking water. However, many drinking water have been polluted by various germs, microorganisms, heavy metals and compounds, which seriously endanger people's health. Therefore, a lot of drinking water filtration and purification equipment have emerged to provide people with safe and hygienic drinking water. The pure water machine made on the principle of liquid reverse osmosis is one of the most common water purification treatment equipment. [0003] In the pure water machine disclosed in the prior art, the core components of the pure water machine are the pressure pump and the reverse osmosis membrane, and the working performance of the pressure pump and the reverse osmosis membrane mainly depends on their working pressure ...

Problems solved by technology

[0003] In the pure water machine disclosed in the prior art, the core components of the pure water machine are the pressure pump and the reverse osmosis membrane, and the working performance of the pressure pump and the reverse osmosis membrane mainly depends on their working pressure conditions. However, the existing Most of the pure water machines do not effectively monitor the working pressure of the pressure pump and reverse osmosis membrane

In commonly used pure water machines, the working pressure of the reverse osmosis membrane is 60psi~125psi. When the pressure in front of the reverse osmosis membrane is less than 60psi, the water molecules cannot effectively pass through the reverse osmosis membrane, and the desalination rate of the equipment is low. It is difficult to achieve the purpose of producing pure water well, and when the pressure in front of the reverse osmosis membrane is greater than 125psi, the osmotic membrane will be damaged due to excessive pressure. At the same time, the pressure of the pressure pump is also above 125psi, and the pressure of the pressure pump The diaphragm will be torn due to excessive water pressure, which will affect the normal operation of the pressure pump and greatly shorten the service life of the whole machine

Therefore, the pure water machine without effective monitoring of the working pressure of the pressure pump and the reverse osmosis membrane has low control accuracy, and the equipment cannot be protected in real time, and the equipment will often be damaged due to the low or high working pressure. Not working or damaged, reducing the performance and life of the whole machine

In addition, there are two shortcomings in the commonly used pure water machines: first, the equipment often lacks accurate water quality monitoring devices, and the water quality monitoring is not strict, which poses a great hidden danger to the health of drinkers; Most pure water machines use mechanical micro switches, which have low control precision and slow response speed. When the equipment fails, the protection signal is often not delivered in time, which is easy to cause damage to the equipment.
