Applications

Ⅰ、 WQD.WQ Waste/sewage Submersible Pump

1. Use and characteristics

  This series of pumps is electric drainage and irrigation equipment that is composed of motor and pump structure below the water pump. It adopts a stainless steel motor shaft. Double mechanical seal is used between water pump and motor. All fixed seam allowances use O-ring for static sealing. This series of motor pumps is applicable to irrigation and drainage of sewage at construction site, coal mine, printing and dyeing and textile industries and is able to pump solid particles like staple fibers, scraps of paper and sediment. Pumps of certain specification adopt channel impellers which can greatly improve anti-clogging capability of water pumps. Thus they are ideal equipment for agricultural irrigation and drainage, and also river & pond desilting.

2. Working condition

  Pmped medium is serous fluid at constant temperature (lower than 40℃ and at PH4-10). Volume ratio of solid phase materials of the pumped medium is below 2%. Lift of submersible motor pump should not be too low, because a lift that is lower than 80% of specified value will easily cause the running of thermal protector, thus make pump stop operation and even bring about damage to the motor.

  Sewage pump is used to irrigate and drain thick serous fluid. It must be stored only after automatically running and washed in clean water for several minutes.


II 、 Q D X. QX.QY Series Small Submersible Pump

1. Use and characteristics

  D X. QX.QY series small submersible pump consists of water pump and motor. This series of pumps is featured by small volume, compact structure and light weight and is particularly applicable to farmland irrigation, oxygenation water supply and drainage in breeding industry, garden sprinkling and water supply for hotels, restaurants and high-rise buildings.

2. Working conditions

  mped medium is normal clean water. Its max water temperature should not be greater than 40℃. Volume ratio of solid impurity in the medium should not be larger than 0.1%, particle size no more than 0.2mm and PH value at 6.5-8.5. For example: river water, lake water and well water.

  Pump should be used within specified lift. Input supply frequency is 50Hz and voltage is 220V (for single phase) and 380V for (three-phase). Magnitude of voltage fluctuation should not be greater than 10%.

  In working, the pump should be completely immersed into water. Immersion depth should not be larger than 5m.


III. QJ(D)Y Series Multi-stage Submersible Pump for Wells

1. Use and characteristics

QJ(D)Y submersible pump for wells is composed of water pump, seal and motor. Water pump over the motor consists of multi-stage impeller and warp-wise guide blade. Mechanical seal is used between water pump and motor. All fixed seam allowances use O-ring for static sealing. This type of water pump is featured by high lift and is applicable to water lifting in deep wells, urban water supply, fire water supply, pipeline pressurization and long-distance water supply.

2. Working conditions

  Pumped medium is normal clean water. Its max water temperature should not be greater than 40℃. Volume ratio of solid impurity in the medium should not be larger than 0.1%, particle size no more than 0.2mm and PH value at 6.5-8.5. For example: river water, lake water and well water.

  Pump should be used within specified lift. Input supply frequency is 50Hz and voltage is 220V (for single phase) and 380V for (three-phase). Magnitude of voltage fluctuation should not be greater than 10%.

  In working, the pump should be completely immersed into water. Immersion depth should not be larger than 20m
