Contact: Miss Europe Contact: 159-7414-3465 Online QQ: 1922601218 a secondary water supply equipment introduction of new products using conventional secondary pressure water supply equipment, the use of sealed tanks, so that the local water supply booster achieve the purpose, it Work is the pump starts, the water into the tank through the check valve, so that the tank body pressure, when the pressure reaches the set limit on the pressure, pressure automatic controller automatically turn off the pump, the pump stops running. Due to the water tank body pressure is higher than the water supply network pressure, automatic blood pressure water supply, when the pressure is reduced to the set pressure limit, the automatic control of pump start, automatic water tank to the water, and so forth, Hanson secondary water supply equipment On the basis of the existing water supply pressure on the bold innovation, the integration of the world's advanced inverter technology, PID regulation technology, changing the traditional pressure water supply for constant pressure water supply. Replace the original must be some pressure tank. And the pump frequency control, according to changes in water to adjust the pump speed, not only can save a lot of energy, but also reduces the pump running noise, ting long pump life. Secondary water supply equipment with novel technological advantage. Second, the main principles of secondary water supply equipment Hanson secondary water supply equipment through the analog signal detection pipeline pressure sensor, the signal transmitted to the microcomputer controller P and P0 are compared with the set value, with a comparison of the results of P as an adjustment to change the frequency parameter output frequency f. Because the pump speed and outlet pressure P n are proportional to the frequency f. So, when PP0, decreased frequency f, n pump speed slows, P down this way, the system pressure P is always close to the set pressure P0. When the system is the thermal expansion of water, resulting in a higher pressure than the upper limit set alarm pressure value, the system automatically opens the pressure relief valve discharge control blood pressure, when the pressure returns to normal, the pressure relief valve closes automatically stop sluicing down. Third, the secondary water supply equipment technical parameters Flow range 0-600 m3 / h pressure range 0-2.0MPa control the pump motor power ≤180KW single precision pressure regulator ≤0.01MP ambient temperature 0 ~ + 40 ℃ relative humidity of 90% or less (electricity control section) Power 380V × (1 + 10%) 50Hz + 2Hz four, no negative pressure water equipment applications (1) applies to the geographical scope: Suitable for ample areas Chengshiguanwang pressure pressurized water; (2) the applicable engineering Type: Large water supply intermediate industrial and mining production, domestic water, water plant booster pump station; (3) applicable engineering areas: secondary pressurized water supply system; (4) Other Scope: new construction, renovation, expansion of residential buildings, office buildings, hotels, restaurants and other public buildings, domestic water; (5) the use of unit types: design units, construction units, supervision units.
