Big-flow pure water supplying equipment and pure water producing technology

The invention provides big-flow pure water supplying equipment. The big-flow pure water supplying equipment is characterized by comprising a raw water booster pump, a pre-filter device, a precision filter, a high-pressure pump, an RO system and a pure water tank, and further comprises a loop pressure adjusting device, wherein the raw water booster pump, the pre-filter device, the precision filter,the high-pressure pump, the RO system and the pure water tank are connected in sequence from a raw water end to a water supply end, and the loop pressure adjusting device is used for adjusting watersupply pressure of the pure water tank. The invention further provides a pure water producing technology based on the big-flow pure water supplying equipment. According to the pure water producing technology, the loop pressure adjusting device is applied to make the water supplying pressure of the pure water tank and the pressure of the water supply end balanced, pipe pressure fluctuation caused by pure water supplying ins
