Q:25KW what is the lift of the pump?
2 floor, the following formula is not accurate, the margin of safety is too large.N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85As follows: for reference only: (pump flow * pump lift) / (367* pump efficiency) * pump motor power safety margin (constant general take 1.1-1.2) = pump power.Unit: flow M3/H, head MNow you know the power of the pump, but you do not know the efficiency of the pump and flow, so the pump head can not be calculated.Can the normal operation of pump flow velocity detection using ultrasonic detection equipment, combined with the calculation of pump diameter of the flow and shaft power testing equipment can use foreign advanced measure pump, electric motor with related input parameters to calculate the pump efficiency. Then use the formula above to calculate the pump head.The simple way is to ask the designer directly about the design parameters.
Q:Power flow conversion of water pump
Pump shaft power (kw) = water supply (L / s) x lift (m) /102 * efficiency = flow * lift * density * acceleration of gravity.Explanation:102 is the unit collation constant.Pump effective power / pump shaft power = pump efficiency (general 50%--90%, large pump higher)Unit time pump liquid volume flow is, flow by Q, a unit of measure: m3 / h (m3/h), L / S (l/s), L/s=3.6 m3/h=0.06 m3/min=60L/minG=Q G refers to weight - liquid proportionThe energy obtained by pumping a liquid of a unit weight is called a lift. The pump head, including suction stroke, is approximately the difference between the pump outlet and inlet pressure. The lift is expressed in H, and the unit is m.The efficiency of a pump is the ratio of the effective power to the axial power of the pump. ETA =Pe/P pump power usually refers to the input power, the motive power to the pump shaft, it is also called the shaft power, denoted by P. Effective power is the product of pump head and mass flow and gravity acceleration
Q:Submersible pump reverse impact on the pump
Water pump is easy to burn out.Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. Mainly used for irrigation and high mountain areas, drinking water, but also for the central air conditioning cooling, heat pump, cooling pump unit, city, factories, mines, railways, construction site drainage use. The general flow can be achieved (5m per hour, fand fand ~650m) head can reach 10-550 meters.There are several kinds of electric submersible pump, in line package is oil immersed and water invasion there is dry must first read the instructions before use, cannot be wrong, not long before use, must have to make the impeller turn, or because of long time card dead burning.Before the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube.At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
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:What is the defection of water pump
Reversing the pump will cause the motor to increase current, small water or no water
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
The design code of sprinkler system GB 50084 - 2001 (2005 Edition) stipulates that the sprinkler system shall be provided with an independent water supply pump, that is, the water pump shall not be shared with the hydrant system. The aim is to ensure the reliability of the water supply and prevent interference.See the code for design of automatic sprinkler system, GB 50084 - 2001 (2005 Edition), 10.2.1 and the corresponding provisions of the following interpretation.
Q:How do I calculate the power of the pump?
Power P (kw) =9.81*Q (second cubic meter) *H (head, unit m) / efficiency;The efficiency can be found on the pump nameplate or sample.This is the rated power, if the head down, the flow increases, the power will increase, so the actual motor power is often much larger than this calculation.Generally buy pumps are equipped with motors, manufacturers can refer to the same model or similar models of motor power.
Q:Pump flow 6M3/H is an hour, how many tons of water?
Flow 6M3/H, that is, an hour can smoke 6 tons of water. But according to the power, head and flow calculated by formula, the water pump efficiency is 98%, can it be achieved?
Q:What are the commonly used tools for repairing water pumps?
Because had done a mechanic, and relates to a pump, not including motor repair, commonly used tools: pliers, pliers, adjustable wrench, wrench, screwdriver, bench drill, multimeter, electric iron, Lamar, hammer, ruler, chisel. Commonly used parts: bearings, impellers, screws, terminals, lubricants and so on.
Q:Pump head is too high what's the impact?
Water pressure is too large, energy consumption is too high, you can choose near the flow of Yang Cheng
