Seiko quality driven water Shengbokaisi no negative frequency constant pressure water supply equipment without negative pressure water supply equipment is no negative pressure device and the constant frequency of equipment consisting of water supply equipment. No negative pressure device is divided into open and closed, open-flow regulator for stainless steel tanks (tank said non-vacuum equipment). The devices connected to the municipal water system pipe network where insufficient pressure, the device is detected by the pressure sensor outlet pressure, the detection value and the set value, calculated on the basis of the existing municipal water pipe network pressure on the need to increase the pressure value determine the number of units in operation and the pump output frequency (response to the motor and pump for speed) constant pressure to conform to the curve of water. No negative constant pressure water supply equipment to maximize the use of existing municipal water pipe network pressure on municipal water pipe network does not produce negative pressure, replace the old tanks with stainless steel tanks or non-vacuum tank, reducing secondary pollution of water . Is a new generation of energy-saving products in the field of water supply. Scope 1. living water: as high-rise buildings, residential areas, villas, etc. 2. Public places: such as hospitals, schools, stadiums, golf courses, airports, etc. 3. Commercial Building: such as hotels, office buildings, shopping malls, large sauna four irrigation: such as parks, playgrounds, orchards, farms, etc. 5. Manufacturing: 6. Others such as manufacturing, cleaning equipment, food industry, factories, etc.: Pool water and other forms of transformation Shengbokaisi often used stainless steel tanks SUS304, SUS316L, SUS444, such as stainless steel, metal forming. General stamping into three dimensions, namely, 1x1 meters, 1x0.5 meters and 0.5x0.5 meters three, surrounding by TIG welding of high strength, light weight, low cost, environmental health and other characteristics.
