Description:

QW type submersible nonclog sewage pump is made up of motor and pump, they are separated through oil isolation room and mechanical seal, it is short in length that motor and pump share the same axle (rotor), the structure is compact. Equipped with many kinds of protectors, it is running reliably, the function of its main parts are as follows:
 1. signal line: equipped with control box, protecting the pump fully, including leakage, phase reversal, short circuit, overheated, overload, etc
2. motor stator: its insulation is B grade or F grade.
3.water leakage probe. This component is installed in the oil room, if the mechanical seal was damaged, and water enters into the oil room, it will send out the signal to the control system so as to protect the pump.
4.Mechanical seal: Adopting in-series seal, the material is the wear-resisting carbonization tungsten, featuring being reliable, wear resisting, longer life, etc.
5.Impeller: have better handling capacity, can reduce the trouble of jamming and twisting of big fiber rubbish, etc.
6.Pump body: harmonize with impeller, ensure the pump has high efficiency.
7. seal rings: Installed at the mouth place of pump body, make mouth surround as impeller office wear and tear, can change the sealed ring because of operating, so as to ensure the pump runs with the best efficiency.

Q:QDX is a submersible pump. What does "X" mean?
It should be small.There is no "downdraft" term;Do not say submersible pumps do not suck, what kind of pump is not on suction, or left and right suction
Q:1.5KW water pump caliber is 40, what is the flow rate?
Caliber 40 pumps, 1.5KW model IRG40-160A, flow 5.9 cubic meters, 28 meters per hour head
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:Do you need a stop valve for the pump at home?
It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
Q:The wiper pump is broken. How much will it cost to fix it?
This can not be repaired, can only be replaced, change a thirty or forty
Q:What motor with Grundfos pumps
General Motors Malaysia gelanfu! Can also be optional!
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
Q:Fully automatic self-priming pump
It's difficult to answer your question only from the name you give! There are many automatic self suction pumps on the market. Generally, the pump outlet is equipped with a pressure switch. It starts automatically when the pressure is low, and stops after a certain pressure.If the pump outlet is the pool (water tank), then it is not a simple "automatic self-priming pump".It is an automatic water supply system. The whole system includes water pump, water tank, liquid level meter, electromagnetic starter (contactor), switch and so on
Q:Pump head is too high what's the impact?
Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.
Q:37KW how many contactors does the pump need to start directly?
First of all, you have to see what voltage you use If 380V then current per KW is about 2A, if it is 660V per KW at about 1.1A, then it is the starting current is 3 to 7 times for the starting current, but for the moment, 380V voltage: 37*2=74A 100A on the line, 660V voltage: 37*1.1=40.7A 63A on the line.
