Q:What is the water pump population pre rotation, what harm?
The turbulence formation flow entrance, the flow direction is complex, impact, vibration, easy to damage the device before; if there is no water pump entrance pre swirl design will affect the safety and service life of equipment.
Q:1 water pump frequency converter constant pressure water supply wiring diagram
This depends on the frequency converter manual wiring diagram. Each converter is different. You're good at this converter.
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.
Q:Why does the pump decay when connected in parallel?
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
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:Water pump eliminates air
By rotating the water pump is thrown from the impeller center, resulting in pressure, the back of the water sucking over, this is the pump working principle, if air, air will not be left out without impeller, the flow rule, no pressure, so we can not draw water!
Q:What is the defection of water pump
Water pump installation of a one-way valve on it.
Q:Water pump motor overload
170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180
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:Does the pump accessories have a shelf life?
Yes, it's probably a year
