Q:The reason why the pump is overloaded
The description of the problem is very clear. Most of this kind of circumstance is overload, is also the outlet pressure is very low, the flow is greater than the rated value caused by the resistance can be adjusted by increasing exports or close the outlet valve, reducing the flow resistance increased by less than or equal to the rated flow. Lift is not an influencing factor.
Q:About how to calculate the pump installation height?
When the water temperature is 4 degrees centigrade, the water pump is installed on the theoretical height of 10.33 meters, is the atmospheric pressure to the hydraulic pump inlet to the level of theory, in practical engineering, the water flow in the pipeline will produce resistance and other factors, the actual installation height generally less than 7 meters. The installation height limit of the pump shall be less than the design suction stroke of the pump.
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP55 represents the waterproof and dustproof rating of the motor
Q:Water pump motor often inlet
I don't know what the pump is upstairsThe ordinary centrifugal pump inlet outdoor installation, in order to prevent the motor fan end can be installed in the end of 0.5 with the maple leaf canopy, the sheet can be, the supporting leg can be installed in the wind leaf cover screws; if your motor output is water, and the output end of the motor bearing can be installed with the same motor shaft the outer diameter of the rubber water retaining ring (the market for rubber seal should be easy to buy)Submersible pump (pump) often water, you should consider replacing the good points of the mechanical seal, such as to choose oil resistant, acid and alkali resistant, selected according to the transmission medium and the pump itself, if you can confirm the correct, check whether the pump shaft bending, made into concentric mechanical seal damage. And check whether the casting on the motor side is defective or not;Choose a higher level of protection of sewage pump, preferably in the pump leakage probe, float switch, overload, lack of protection, generally will not burn the motor
Q:TDH what units are present in the pump parameters?
TDH, Total, Discharge, Head, that means the head, the unit is usually feet. 1 feet =0.3048 meters.
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:Relationship between power and flow of sewage pump
There is a formula for motor power = flow (m3/h) * lift head (meter), *9.81/3600/ efficiency (general sewage pump efficiency is about 55%), *1.2 (motor safety factor)For example, 10 tons of flow, lift 10 meters, how much power?N=10*10*9.81/3600/0.55*1.2=0.595. so the motor power we chose should be 0.75KW
Q:50 meters deep well with what water pump: home?
What types of household water pump, self-priming pump, centrifugal pump, submersible pump, according to the size and utility of water pump, self suction pump is the advantage of direct water, normal household to 1500 watts can, but must keep the water clean, water there can be no silt or small sand. Centrifugal pump need drinking water, that is not self suction;But the advantage is a large amount of water. When used, the power will be reduced, because the use of centrifugal switch is automatically disconnected, energy savings can be used, the general household on these two, as for submersible pumps, home generally less than.
Q:The water burst how to repair?
This is used by welding and making AB calls
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.
