Usually we say no negative pressure water equipment without negative pressure water equipment manufacturers, generally refers to no negative frequency of water supply equipment without negative pressure water equipment purchases, also called frequency without negative pressure water equipment, is directly connected to the water supply pipe line pressurized equipment. The traditional way of water supply reservoir is inseparable from how much negative pressure water equipment, water reservoir supplying water pipes in general, after such pressure water into the pool becomes zero, resulting in a large amount of energy wasted original. No negative pressure water: the negative pressure water main by non-negative steady flow tank, pressure tank (diaphragm or bladder-type expansion tank), negative control cabinet, pumps, motors, filters, backflow prevention device, sensors, electrical contacts, piping components, chassis and other components. On the market there are various forms of non-vacuum equipment: 1. regulator compensated negative pressure water equipment box 2. 3. overlying negative pressure water equipment high water supply of high-quality equipment 4. No Tap Water Pressure Station negative pressure water equipment, negative pressure water supply equipment, energy saving is provided by Rui Teng Teng Rui energy-saving equipment Anyang City Limited.
