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 suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
- A standard atmospheric pressure can be 10.33 meters to 30 meters of water, suction is atmospheric pressure there are three standard atmospheric pressure so high? This is impossible in general, remove the vaporization removed 0.5 meters critical yo,
- Q: What are the causes of pump shock?
- 3. the water pump set screws loose, adjust the concentric, fastening the foot4. pump into foreign body, open cover overhaul5. the flow is too large or too small, adjust the equipment to control the water output
- Q: How to select metering pump head?
- The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.
- Q: What is double hydraulic pump?
- The 2 pumps are all coaxial connected together, driven by a motor, the general gear pump, piston pump
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.
- Q: How many kinds of pumps are available and the operating principles of various pumps?
- There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..
- Q: What are the main performance parameters of hydraulic pumps?
- speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q: What are the parts of a pump? How do you classify it?I just want to know
- According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
- Q: Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?
- Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
