Q:About how to calculate the pump installation height?
See the design manual, town water, volume P312This formula is: NPSHA = HgHzhsZs > NPSHRAccording to the actual installation of NPSHA pump cavitation can provideThe pump NPSH provides NPSHR pump samplesAtmospheric pressure Hg pump installation siteHz liquid under certain temperature saturated steam pressure.The head loss of water pipe HsThe installation height of ZsIt is worth pointing out that, with regard to Hz, with temperature related, and some problems are not given temperature, and that value is also very small, in the calculation should be able to ignore (0 degrees C, 0.06mH2O).And atmospheric pressure, we usually use 10mH2O, in fact, and altitude also related. When the altitude is 0, it is 10.3
Q:What's the submersible pump?
Centrifugal pump, a general motor and pump body is one, you can pump the whole pump into the water
Q:Water pump "rated lift: 6m" what do you mean?
Popularly speaking, "lift head" is the ability of water pump to lift water. 6m means that the pump can pump water to the height of 6m.
Q:I have a mechanical well how to choose the size of the pump
Deep well pumps can be used. According to your parameters. 0. 75 or 1. The 1KW deep well pump is in line with your requirements. Elephant 0. 75KW head can reach 70 meters. The water output in an hour is about 3 tons.. I wonder how much you get out of the water every hour. If the amount of water is small, you can buy a larger power point. General domestic deep well pump 0. 75 or 1. The price of 1KW is between 500-700. In the case of ordinary brands. The price of imported goods is between 600-900. The products at this price are generally of good quality.. Of course they don't sell your shoddy premise.
Q:How to remotely control submersible pumps?
Now the remote control of submersible pumps and pumps is very mature, and the cost is relatively low. We use the Ji'nan Huichi electronic pump remote controller controlled step-down start control cabinet, convenient Clockwork SMS can control the pump start and stop, and return to the working condition of the water pump, water pump overload or lack of power can also feedback fault message to the responsible person
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
According to the water quality difference, the purpose is to provide the corresponding cooling water, for the system oil cooler, machine seal and other cooling. Open water directly from the circulating water pipe to use, the pump is delivered to the host, the small machine oil cooler, water quality is not very high, the circulating water drainage to the back pipe, water through the water filter filter impurities. The closed water takes the self closing water tank, which is used for removing salt water. General supply pumps, water pumps, sealing cooling water, condensate pumps, sealing water, generator, hydrogen cooler and other requirements of good water quality system, closed water self circulation, and through the cooler and open water circulating water heat exchange.
Q:55KW how large is the water pump wiring?
Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.
Q:How can the pump be stationary?
1, the pump can move under the premise of turning disc. Pump should be empty load start, that is, in the closing of the export valve in the state of start, there will be no rotation of the situation.2, look at the voltage of the circuit is normal, whether the lack of phase.
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:Diving pump voltage
Absolutely not, because 220V is not the same as the 380V waveform. Submersible pump single-phase motor is generally single-phase capacitor motor. The working principle is different from that of the single-phase 380 motor. If the power capacity is enough, it is recommended that you increase the wire (you can buy a line and go to use, to avoid waste), preferably with copper wire.
