Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
Lift is usually used to overcome vertical height and pipe loss. Now you can determine the vertical height of 30 meters, 230 meters long pipeline losses but you lack of data not calculated. With the following conditions can be calculated: 1, flow; 2, pipe diameter; 3; pipeline material; 4, elbow number; 5, valve types and quantities.
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:How large is the starting current for a 1.5 kW submersible pump?
The starting current is 2-7 times the power
Q:How to connect the household pump capacitor?
1) in a line in the AC220V string into a large light bulb (Bai Chideng), and then the capacitor as shown in figure A, then, that B and C are three terminals; 2) the number of pump motor three lines 1, 2 and 3; 3) A, B, C and 1 2, 3, a total of six kinds of wiring combination: ABC/123, ABC/ 231, ABC/321, ABC213, ABC132 ABC312; 4) you have a a try, if you can turn up, and the fastest start wiring is correct, 5) if not turn up, you have to increase the number of watt bulb, such as 200 watts, 300 watts, 500 watts...... With a few 100 watt parallel one; 6) string into the bulb is designed to prevent the current is too large, it certainly must be removed after determining the connection method; 7) there is no suitable bulb that according to the motor power generation to choose the appropriate insurance.
Q:What does the temperature range of the pump mean?
Not be too cold or hot water, will be frozen.
Q:How to determine the pump installation elevation, why should we determine the pump installation elevation?
This depends on the water pump cavitation, in theory, suction is equal to the atmospheric pressure minus the margin, the installation is too high to suck the water ah. What kind of pumps do you want?.
Q:What is a 1 inch water pump?
The outlet is 1 inches (25MM) of the water pump
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Pump selection is based on flow, lift, power to determine, the actual situation is different, the choice of pump specifications and models are different, the key to your needs to choose.
Q:Pump power ratio design is small, the problem is big?
No problem, despite the good use of different water pump factory manufacturing process is different, the product of the rich value of different factors, power difference is inevitable, as long as the flow and head to meet your use requirements.The calculation formula tells you: your flow is 72 tons / hour, lift 90 meters, motor power P=2.73HQ/0.75*1.2=28.5KW
