What is a centrifugal pump and how does it work?
A centrifugal pump has a bit that spins round, (an impellor) inside a case. When the inside of the casing is full of liquid and the bit inside spins round, the fluid is flung outward to the sides, by centrifugal force. An outlet pipe in the case allows the fluid to exit.If the fluid exits, then something must take it's place, a vacuum is formed. The point where cenrifugal force has least effect, is the dead centre of the bit that spins, the impellor. Arrangement is made in the casing (volute), for fluid to enter at the centre of the impellor and get flung to the sides again.A cenrifugal pump needs to be full of fluid, before it can act as a pump. They are no good at gasses, like air. They are best placed below a liquid so that they fill naturally. They can be made to work above a liquid, but must first be filled with liquid, before starting. This is known as 'priming'.
How does an electric siren work?
An electric siren works by connecting the positive and negotive wires to the correct places. The current flows through and powers a small speaker. An air raid siren works by having an impellor and a cover. The cover has holes and as the impellor spins, it pushes out air and causes a deep and loud sound.
Your aquaclear power filter has stopped working?
It's possible the impellor is gunked up and the motor froze. Remove the black motor portion from the plastic container. Gently pull the impellor out and clean with an old toothbrush, try using one or two Q-Tips to clean the channel where the impellor spins, be careful not to damage the guide pin. Reassemble everything and try using the power filter in water, filter should never ever be used without water. If you don't hear any noise from the motor, try tapping on the motor housing to unfreeze the motor, it that doesn't work, it's time to purchase a new power filter.
How does a regenerative pump work?
Turbine is confusing - regenerative is better. The energy within the impellor, which is divided into small segmented compartments is regenerated many times to increase the head pressure. The trade off is low volume.
I have a 2001 grand Cherokee AC is cold but seems to just dribble out even on high. At the same time the blower motor below the glove compartment makes a whirring sound - louder when on high. ideas?
Perhaps the impellor on the fan motor is loose or broken
What could cause a 1995 dodge ram 1500 pickup to overheat?
Low coolant? Thermostat not opening? Radiator plugged? Radiator air flow restricted? Hoses collapsing? System airbound? Water pump not working (defective impellor)? Bad radiator cap?
What causes the alternator to get very hot after just a few minutes of running on a 1991 Ford F-1506 4 speed manual?
Check for the impellor or fan rubbing on the casing. Check for worm bearings. If the alternator is running at full load the casing will become hot
Can a 1998 Subaru Legacy water pump be faulty with no signs of leaking?
yes it could be faulty without leaking , the impellor on the back could of come away and not be pumping water around the engine , to check this take the radiator cap off and have a look if the water goes up and down when you excellorate the engine , if it does the must be a nother problem
Why will your 2001 mercury 4 stroke outboard not operate at more than 2400 RPM?
My 115 EFI mercury outboard would only generate 4200 RPM. The power gradually reduced and finally levelled off at 2400 RPM. I have had other problems in the past relating to power settings. Fuel injectors and impellor have been eliminated as potential causes.
Your 6hp mercury out board motor got hot and shut down it even melted pee hose you seem to still have compression took foot off and impellor neede to be replaced?
Sounds like the cooling hose clogged so cooling water wasn't flowing through the outboard, causing the engine to overheat. Some engines have an overheat alarm for this, but probably not a 6 HP.
What happens if for whatever reason the water level drops and your pool pump runs without water for over 4 hours?
If water does not flow through your pump while the pump is operating the pump will "loose prime" what remaining water in the pump will boil from the friction of the impellor spinning, this will turn the water to steam and melt the plastic parts. Also known as the pump has "Dry Run"
What are some eight letter words with 1st letter I and 3rd letter P and 6th letter L and 7th letter O?
