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: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:The role of impeller in water pump
Pump impeller through the motor to drive rotation, so that the medium (water) by centrifugal force or lifting force, so that the medium has mechanical energy (kinetic energy)
Q:How can I pump the motor insulation?
The cable head in the distribution box should be relieved. What's more, the motor insulation is not the pump insulation. Usually, just shake it in the middle of the water and the ground.
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:What does diving pump 80JYWQ40-15-1600-4 stand for?
3, sewage pump flow per hour 40 square water head 15 meters, 1600 rpm, with power 4KW
Q:How to introduce water pump?
The so-called Practice makes perfect., read the three hundred Tang poems will not recite poetry.Suggest a good understanding of the basic knowledge of water pumps, industry trends, understand the needs of the industry, as an expert in the industry!
Q:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:Water pump part is stainless steel, which part is it?
Of any part of the body that is in contact with water
Q:How many pumps does a 50 meter water head use?
Well pump head selection for pump + water depth height (water pressure) + head loss, head loss of water system is not complicated with 3-5 meters can, refers to the depth of pump well pump down into the well depth, generally shallow wells is down to the bottom, is based on deep well pumping well test data to determine the position of the pump.
