Product introduction:
QD/Q series submersible pump consists of pump, mechanical seal and motor. Pump is at the bottom part of pump,which is adopted centrifugal impeller.Motor which is monophase or triphase is at the upper part of pump and seal is used where pump and motor combine, which is a kind of double end mechanicalseal,"0" rings are applied to all static joints.
Application:
The motor pump is adopted multistage impellers, and has advantage of high head, which is widely used in countryside and industry for elevating water from well, irrigation, sprinkling and tower water supply, and also used in draining off water for building sites.
Work Conditions:
The pump can work properly and continuously under following op¬erational conditions:
1.Medium is not corrosive. Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be
6.5-8.5.
3.The pump should be operated within rated head. The pump should be min.0.5m over the water bottom and not be inserted into sludge.
4.Power frequency should be 50Hz,single phase voltage 220V ， three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.
- Q: The function of centrifugal pump
- The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.
- Q: Advantages and disadvantages of centrifugal pumps?
- The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.
- Q: What are the basic technical parameters of the pump?
- The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
- Q: Does the reservoir water heater press the booster pump (high marks)?
- 60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.
- Q: How many kilograms of water pump are there in the automatic washing machine on the market?
- Suitable for supporting high pressure sprayer, portable car washer. Water pump with overflow circuit. And comes with pressure switch, overflow switch double insurance
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- In general, the pump removes the motor, and all the fittings are part of the pump head.A pump is a machine that transports liquids or pumps liquids.
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.
- Q: Filter backwash pump for what use, what is the principle of work ah?
- But the reverse cleaning can not completely regenerate the filter medium, or there will be some impurities remain, when the regeneration of residual impurities (pressure drop) to set the value, you need to replace the filter (filter media).
- Q: What are the characteristics of the piston pump?
- 1 、 built in overvoltage protection and flow correction system.6 、 large screen LCD display.7. The well designed exhaust device can effectively remove the bubbles in the liquid.8, flow and pressure settings can be memory, and PLC communication (custom).
