Q:What is LG water pump?
LG pump LG refers to the name of the water pump brand, not on behalf of practical significance.LG pump is a high-rise building feed pump.1, LG, LG-B type of high-rise building water supply pump is a vertical multistage type structure, bolt the inlet section, the middle section of the water pump are fixed together, each containing a impeller and the guide vanes, the axial force of the hydraulic balance, the residual axial force by one or a pair of ball bearing;2, the shaft seal adopts special design mechanical seal, so when dismantling mechanical seal, do not need to remove the motor, the middle casing coupling can be removed from the seal, it has the advantages of replacement and convenient maintenance;3, pump transmission is through the shell coupling, vertical motor drive, from the motor side to see, the pump clockwise rotation;4, the suction inlet of the pump is below, the water outlet is above, and its relative position can be chosen according to the user's requirements, 0 degrees, 90 degrees, 180 degrees, 270 degrees for assembly, factory. General pump 180 degrees factory.5, assembly without adjustment, easy disassembly;6, the motor can be equipped with standard Y series of ordinary models.
Q:About water pump selection
Domestic I do not understand, only know that you dock water, it is best to use sea water pump, or allow manufacturers to do your anti-corrosionVille, Grundfos.Lift up, I'll do it. 30m is pretty muchThe self-priming pump is OKWhich brand do you want to use? Just call them directlyLet them count it for you and then type itFirst know about yourself, generally know a power head water quantity on the line
Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
According to the horizontal distance of 10 meters is 1 meters lift, 200 meters is 20 meters and 5 meters height difference of 30 Mega elbow, pump head floating down 10%, should be about 60 meters.
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:Can the water from the fire pump enter the roof fire tank? Why?
This should be divided into two cases, the key depends on the use of your water tank!If you fire water tank roof is a constant pressure water tank fire control system, the requirements must be set on the water tank outlet check valve, which can only flow from the tank outflow, then pump the water can not enter the roof fire water tank.If the roof fire water tank acts as a water transfer tank and uses it to transport water to a higher building, the fire pump water can enter the water tank
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
If you want to install simple, you choose vertical single stage pipeline pump, he imports and exports in a straight line above, installation super simple. If the installation does not require, IS ah, GD ah, you can.
Q:Does the lift of pump relate to the water level of import and export?
What's the relationship?! When the inlet level is low, the head is slightly higher than the liquid level!
Q:Water pump is not Sheung reason
You should look at the suction port of the pump, there is no check valve, if there is water will not flow back to the pump bodyIf the pump is not water and not bad, the main reason is that the pump does not flush water, or suction pipe into the air
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:What does the pump lift mean?
The pump head is the height or length of the distance from the pump to the outlet
