The RO reverse water purifier originated from American space technology and was introduced to China in the 1990s. Reverse osmosis is a membrane separation technique that relies on a reverse osmosis membrane to separate the solvent and solute in solution under pressure. Reverse osmosis is the application of a pressure greater than the natural osmotic pressure in salty water (such as raw water), allowing water to penetrate from the higher concentration side to the lower concentration side, separating the water molecules in the raw water from other substances. Since the micropores on the reverse osmosis membrane are extremely small, the pores are only 0.0001 μ, which is a few thousandth of the volume of bacteria and viruses. The water prepared by this technology is pure water, does not contain any minerals and trace elements, and even can be directly consumed after being filtered by urine. The speed of water passing through the reverse osmosis membrane is extremely low, so the amount of treated water is small. Generally, the ratio of effluent to water inflow is 1:4. The advantages and disadvantages of water osmosis water purifier are as follows: Advantages: The effluent water quality of the reverse osmosis water purifier is safe, and it can remove all kinds of harmful impurities in the water. It has a good effect on the water supply special event, and the water outlet taste is good, which can reduce the hardness of the water. The container does not produce scale after boiling water.
Absolute Encoder
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
