One, QSP type fountain dedicated pump characteristic structural features: The motor is self-circulating cooling water-filled; phase four-wire cable type JHS fountain dedicated cable; impeller anti-loosening devices; color filter cover with full stainless steel; motor rotor cavity imported anti-rust enamel, improved corrosion resistance underwater motor, the above structural improvements to make it more suitable for the requirements of the fountain engineering requirements and flat and horizontal use. Motor Performance: Motor materials Premium DR470 cold-rolled steel evening, increasing the number of turns and the diameter of the pump motor winding resistance to frequent starting. Hydraulic parts: hydraulic model design, the pump flow rate, head, efficiency three more reasonable. Two, QSP type a fountain dedicated pump conditions, special fountain pump should be completely immersed in water running, diving depth of not less than 0.5 meters, no more than 5 meters. 2, ambient water temperature should not be higher than 40 ℃. 3, the working medium is non-corrosive water, sediment concentration of not more than 0.1%, PH value of 6.5 to 8.5. 4, three-phase 50 Hz power supply should ,, rated voltage of 380 volts, the power supply voltage must be guaranteed within the range of 342 to 420 volts. 5, QSP fountain dedicated pump type should be used within the scope of the rated lift nearby. 6, fountain pump should start to configure the appropriate control cabinet grounded. Three, QSP type pump fountain dedicated special purpose QSP type fountain pump is mainly used for large plaza fountain, park fountains, waterfalls, garden fountains, aquaculture and other places. Widely used in the city's residential fountains, garden fountains, agricultural irrigation, sprinkler irrigation; industrial and civil supply, drainage system, hills, mountains water, as well as low-lying land exclude water. Four, QSP type fountain dedicated pump model significance QSP20-30 / 2-3 QSP- 20- fountain dedicated pump flow (m? / H) 30- Head (m) 2- 3- series impeller motor power (kw) five QSP type fountain dedicated pump Ordering Information: Please provide the following details: ① fountain dedicated pump product name and model; ② pump fountain dedicated caliber (mm); ③ fountain dedicated pump head (m); ④ fountain dedicated pump flow ; ⑤ fountain dedicated pump motor power (KW); ⑥ fountain dedicated pump speed (r / min); ⑦ fountain dedicated pump voltage [V]; ⑧ fountain dedicated pump suction (m); ⑨ fountain pump is dedicated with attachments, so that we can correct for your selection.
