Product introduction:
QDX. QX 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 three phase is at the upper pa" of pump and seal is used where pump and motor combine, which is a kind of double end mechanical seal "O " rings are applied to all static joints. Floator switch can be equipped to control pump" starting and stopping automatically according to the water level.

Application:
This series pump is small and light, which is widely used in countryside for elevating water from well, irrigation, sprinkling and domestic water supply, and also used in draining off water for fishpond and building site.

Work Conditions:
The pump can work properly and continuouslyunder following operational conditions:
1 .Medium is not corrosive, Sand contents shouldbe max. 0.10% by volume and granular sizeshould be max.0.2mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be6.5-8.5.
3.The pumps should be operated within rated head.
4.The pumps should be fully submerged into water with depth of less than 3m mad max. the pump should be min.0.5m over the water bottom and not be inserted into sludge.
5.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: Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q: What is the minimum continuous flow of a pump?
At'-- the allowable temperature rise of pumping medium,C- pumping medium specific heat, kj/ (kg DEG C);Ho- off dead center lift, M.Minimum continuous flow minimum continuous stable flow and minimum continuous thermal flow and the maximum value in the selection, or use the pump process, the minimum continuous flow process requirements must be greater than the minimum flow rate of the pump, otherwise it will cause the pump cavitation, vibration and noise, so that the pump parts damaged. If the minimum continuous flow the pump can not meet the minimum requirement's process, can install the bypass reflux device or reflux system in the pump pipeline, to ensure that the minimum continuous flow pump.
Q: What is the dry running protector of screw pump? What's the principle and function? Thank you
The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
Q: If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q: Is vane pump good or gear pump good?
The main parts of a gear pump are gears that mesh with each other. The meshing driving gear and the driven gear are respectively arranged on two parallel rotating shafts. Because the gear teeth enter and exit the meshes, the volume of the teeth is changed, and the suction and discharge effect is formed.
Q: Which nuclear submarines use the shaftless pump technology?
At present, the submarine has been used in the pump jet technology, the most representative is the United States Virginia class submarine and the Russian North Sea God class submarines.. And shaftless pump is a derivative application of superconducting technology, which is more advanced than pump jet technology..If you want to learn more about shaftless pump technology, you can find relevant papers online.
Q: Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
Q: Do you have a suction pump higher than 9 meters?
Pump rated suction generally 7 meters or so, it is estimated that no one calibration pump suction stroke 9 meters. Calibration suction range of 9 meters is not reliable.
Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
