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:What is the current of the pump when it is started?
When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.
Q:Submersible pump reverse impact on the pump
Small amount of water, large current, long running time, easy overheating, or even burning pump.
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 mutual switching device
You can refer to the DCL and DCS microcomputer access control system, you can achieve the purpose of remote control. Specific installation methods can be found in local instrument engineering inquiries.
Q:What does water flow mean?
The quantity of water produced per hour
Q:Pump frequent start will reduce the service life, I ask what kind of frequency is called frequent start?
How to define this frequently, this can only say, for example, the life of the switch is 60 thousand times, once every hour you move, it can be used for a long time, and that if you move one minute, it would not necessarily for long.Pumps frequently start the first self wear problems, as well as the impact on the pipe network, especially the soft connections.Water pump if the frequency of use or time, it is recommended to adopt: variable frequency constant pressure control.
Q:What is a 1 inch water pump?
The caliber of the water inlet and outlet pipe is 1 inches of water pump,
Q:How many lift pumps should be used for 100 meters tall buildings?
At least 130m guarantee that the top floor customer has 3KG water pressure
Q:Pump performance parameters have three sets of data, how to understand the flow, lift, flow speed
Mainly expressed the ability of the pump, mainly as a basis for selecting the pump users.Lift represents the performance of the pump to boost water pressure. Such as the pump head H=38 meters, that the pump outlet pressure normal to 0.38MPa.The flow rate represents the water supply capacity of the pump. Such as 100 m3/h. The general flow pump design, and the corresponding flow, little significance.
