Q:About how to calculate the pump installation height?
When the water temperature is 4 degrees centigrade, the water pump is installed on the theoretical height of 10.33 meters, is the atmospheric pressure to the hydraulic pump inlet to the level of theory, in practical engineering, the water flow in the pipeline will produce resistance and other factors, the actual installation height generally less than 7 meters. The installation height limit of the pump shall be less than the design suction stroke of the pump.
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:Submersible pump and self-priming pump which is easy to use?
If the injection pump, submersible pump is self-priming pump well.
Q:1 water pump frequency converter constant pressure water supply wiring diagram
This depends on the frequency converter manual wiring diagram. Each converter is different. You're good at this converter.
Q:The difference between submersible pumps and centrifugal pumps
Submersible pump refers to the installation of pumps in the form of motor and pump body are installed underwater. It can be a sewage pump or a clean water pump or other purpose.Sewage pump to see the name will know, that is, playing sewage, you can use submersible pumps, you can also use other forms of pump.
Q:Relationship between power and flow of sewage pump
If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.
Q:50 meters deep well with what water pump: home?
What types of household water pump, self-priming pump, centrifugal pump, submersible pump, according to the size and utility of water pump, self suction pump is the advantage of direct water, normal household to 1500 watts can, but must keep the water clean, water there can be no silt or small sand. Centrifugal pump need drinking water, that is not self suction;But the advantage is a large amount of water. When used, the power will be reduced, because the use of centrifugal switch is automatically disconnected, energy savings can be used, the general household on these two, as for submersible pumps, home generally less than.
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:Water pump part is stainless steel, which part is it?
An overcurrent unit is a part of a liquid that passes through a pump when it is in contact with the liquid. Such as pump body, pump cover, impeller, shaft, shaft sleeve, impeller mother, key and expansion tube, etc..
Q:After the pump has a control box, but also the distribution box?
1, after the pump has the control box, do not need the distribution box.2. The control box is not the same as the distribution box.Wiring principle is as follows: from the distribution box power supply into the control box, L1, L2, L3 (usually so); from the control box to connect U, V, W to the water pump.
