How Does a Water Pump in a Water Cooler Operate and What Are Its Components?

AI Thread Summary
A water pump in a water cooler typically operates using a small centrifugal pump driven by an electric motor. Common issues with malfunctioning pumps include blocked water lines or a failed motor. Troubleshooting involves checking for water flow and ensuring the motor is receiving electrical power. If the pump is old, corrosion may also be a factor, and replacement parts can often be found online. Repair or replacement decisions should be based on the results of these checks.

I think the most common arrangement would be a small centrifugal pump driven by an electric motor.
If it isn't working, there are a number of possibilities...
(1) the water in or out is blocked
(2) the electric motor has failed

It is really a matter of checking the simplest/easy things first (eg is water in? does the motor run?) and then deciding whether to repair or replace.

Cheers,
Terry
 
Is electrical power getting to the pump? Check volts at the switch and on any connector block (carefully). Does it hum when it's supposed to be on?
It looks fairly elderly to me. Perhaps it has some corrosion inside it. Have you tried eBay for a replacement? If you can find a cheap one and it the present one passes all the tests that have been suggestion then it may not be too upsetting to fork out for a replacement.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
