What is the power calculation formula for Rotary air lock valve?
You need to know the torque the motor needs to produce to operate the valve before you can specify the motor. It's all about the amount of power that needs to be delivered to any application that is critical in specifying motors. Motors are rated according to the power needed, so once you have that, then you can select the motor according to rpm and power supply.
Explain why 3 phase induction motor at no load operates at a very low power factor?
An induction motor electrically appears much like an inductor with a resistive component. The resistive component is reflective of the mechanical power which the motor delivers. There are also some true resistive losses in the motor widings, but these are relatively smalll. At no load both these contribute to the total electrical resistive component of the IM. The resistive component at no load however will be small compared to the IM's inductance, resulting in a very low power factor. As the mechanical load on the motor is increased its effective electrical resistive component increases and so does its power factor. Another way of thinking about this is that a circuit's power factor is indicative of its electrical resistance, which dissipates watts. At no load very little actual electrical power (watts) is required to rotate the IM, so its power factor is low. If the IM is driving a large mechanical load more actual power must be delivered to the IM and this is indicated by a much larger power factor. _____ Under no load slip is almost zero, i.e.. there is almost no induced current in the inner coil. So power factor which is induced power to input power ratio is small. As load increases, slip increases for a given motor and so does the induced current and the torque generated in turn to run the load.
How is the rooftop wind turbine different from other wind energy devices?
The rooftop wind turbine is different from other wind energy devices in that it relies on a small motor in addition to wind power, whereas other devices rely only on wind power.
Is reactive power a vector or scalar?
I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.
What is meant by the term power overlap?
Like, Power Redundancy?
Put a 1 hp impeller on a 2 hp pool motor?
well the motor will like it, it will run cool but the power bill will be high. it will not have the flow of a 2hp impeller
Power required to drive a centrifugal pump is directly proportional to?
Cube of diameter of its impeller
Why is your submersible pump not working?
No power to pump. Motor burned out. Intake is clogged. Impeller disconnected from motor.
Is Power required to drive a centrifugal pump is directly proportional to diameter of the impellor?
yes....power is directly proportional to cube of dia.
How do you calculate 3ph AC motor power?
How do you calculate 3ph AC motor power?
How do you fix a leaking shaft seal on your Hayward SP-1515 power-flo pump?
Replace the seal assembly. Your local pool store should have them in stock. you'll have to remove the strainer basket to get to the impeller. The impeller will then have to be removed. the seal is under the impeller. Remove the impeller by taking the back cover off of your motor. Inside you'll see all the electrics of the motor. In the center, on the shaft, it is slotted to accept a 7/16" wrench. Place a wrench on the shaft and twist off the impeller. Replace the seal assembly and put back together.
How do you get the impeller off the motor super pump 1 hp?
Most pump impellers rotate off in the opposite direction as turning under power. So rotate the impeller anti-clockwise to loosen it. The real trick is to grasp the impeller hard enough to turn it without warping or bending it. There is almost always a screwdriver slot at the other end of the shaft to hold it from rotating as you remove the impeller.
How do you change impeller on Johnson 70 hp outboard?
Changing the impeller on a Johnson 70 hp outboard motor requires pulling the power head and disconnecting the engine. Once this is done, an open end wrench can be used to first loosen the fitting before removal.
How do you calculate machine capacity of overhead router?
Three measurment are given The throat depth of the arm The depth which you can plunge downward The drive power and speeds available from the motor will limit the cutter diameter and capacity to cut
How do you calculate the field diameter of the medium power lens?
The equation goes like this and works for both medium AND high feild diameter : Medium(High) DIA. = Low Diameter / [Med(High)mag/low mag] Brackets () are NOT for multiplication, they are for the other formula.
How do you take an impeller off a hayward power flo lx pool pump?
To remove the impeller from a Hayward Power-Flo LX pool pump, first turn off the power and disconnect the pump from the electrical supply. Next, remove the pump's front cover by unscrewing the screws, then take out the diffuser to access the impeller. Use a socket wrench to unscrew the impeller by turning it counterclockwise, and be cautious of any debris that may have accumulated. Once removed, inspect the impeller for damage or wear before replacing or cleaning it.
How does the blower unit on the High-speed Ribbon Blower get its power?
The blower unit on a High-speed Ribbon Blower typically gets its power from an electric motor. The electric motor drives the impeller inside the blower unit, creating airflow and generating the necessary suction or pressure for the blower to operate efficiently.
