Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Low inlet and outlet
Q:Pump pumping small is what happened?
Multi pass is self-priming pump, right? Check that the water inlet pipe is connected. If there is a little leakage, the lift will not be high. If the submersible pump, impeller pump or screw pump, they do not have irrigation. If it starts small and then flows, it may be that the water in the well is not rising so fast, that is to say, the water is poor. This happens, too. If it starts small, which may be the well did not hit the good position. Suggest a little more. Is it used in your house? Still have other uses?. For home use. A bucket of water is enough.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:How large is the starting current for a 1.5 kW submersible pump?
1KW about 2 current, so the rated current is about 3A, and the starting current is usually 3-8 of the rated current, that is 9-24A.
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 is the minimum liquid temperature allowed at 2 DEG C instead of 0?
0 degrees water turns into a mixture of ice water. Do you think the water pump will work properly?
Q:How should the water pump breaker be selected?
Tell you a way, then go to the election, mainly to see his rated current to choose.The most general calculation of a KW==2 current (380V3 phase) 11KW==22 current, and then enlarge 1.2 times, that is, the current of the circuit breaker is selected to 25-30A. If it is started directly, zoom in to 1.5 times. Yes, no problem!! In addition, the 37KW 64 current short circuit selector 80-100A is ok.. Similarly, 4KW following unification can be done using 10A15A
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.
Q:Pump impeller diameter plus assembly what changes? What's the effect on the motor?
1., the larger the diameter of the impeller, the greater the head, the greater the flow rate, because the flow of water depends on the speed of rotation of the impeller generated by the centrifugal force and the line speed on the tangent, the greater the diameter, the centrifugal force and the greater the speed of the line. The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment.2., the head and impeller diameter is related, the larger the impeller, the greater the head, and vice versa. The flow rate has little to do with the impeller diameter. Under the rated conditions, the greater the head, the smaller the flow rate, inversely proportional.
Q:37KW how many contactors does the pump need to start directly?
Direct start requires 250A contactor.Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to power, power distribution and power consumption. Contactor broadly refers to the use of coils in industrial electricity that flow through the current to produce a magnetic field, so that the contacts are closed so as to control the load of the appliance.
