What is the water speed of the boiler feed water pump?

Introduction The water flow rate of the boiler feed water pump is related to the flow rate and cross-sectional area. Flow rate, power and lift are important parameters of the water pump. linked to the power and lift of the pump.

What is the water speed of the boiler feed water pump?

Water flow is related to flow rate and cross section. Flow rate, power and lift are important parameters of water pumps. In other words, the water flow rate of the water pump is related to the power and lift of the pump.

Flow rate is inversely proportional to height and directly proportional to power.

In addition, the inlet water flow and outlet water flow of the water pump are different. The inlet water velocity is generally 2.5-3m/S and the outlet water velocity is 2.0-2.5m/S.

This is a very complex question. What is the guaranteed flow rate of the additional water source of 3 to 5 m3/S? Besides electricity production, what are the other uses of reservoirs? What is the design water level of the tank? How much traffic is allowed? Is it a riverbed hydroelectric plant or a diversion hydroelectric plant? Oris the site located? What is the annual level of wastewater from the power plant?

The design height H of the generator refers to the difference between the water level of the upstream reservoir and the water level of the tail basin of the power plant under normal generating conditions. 'electricity. The power generation flow rate Q of the power plant refers to the flow rate used for normal power generation, which is lower than the flow rate of the replenishment water source. When the plant throughput is determined, divided by the number of units, it is the electricity production rate Q1 of a single machine. The power generated by a single unit is N1 = 9.8 k Q1 H kilowatts. In the formula, k is the efficiency of the unit. The flow depends on the flow of this part. The flow rate divided by the cross-sectional area of ​​that part is the section flow rate.
