Question:

What are the components of a water pump being used in a car and how does it work?

How do you measure and analyse the pump characteristics and efficiency?

Answer:

Right on sweetheart! I'm with you due to the fact that I do not like being owned via the billionaires on this nation! There's not anything unsuitable with proudly owning used rather then the belief problems! Keeping up Appearances ring any bells? I believe typically it is a subject of jealousy too while anybody is paying $six hundred a month auto cost whilst you trip round on your four 12 months ancient auto cost unfastened and the item runs without end! Believe me, I've bought one! A 1984 GMC in best situation that I purchased while it used to be five years ancient and all I have ever performed to this can be a $1159 modern day substitute engine! The factor simply maintains going and going, we use it for snowplowing, getting firewood, at the farm for each chore conceivable, ingredients truck at my fix save and many others! So, preserve up the spirits and do not fear what different humans believe! I have an ancient announcing, if you do not like me or what I am then keep away! I used to be right here earlier than with out you and I'll be right here after wards with out you! Firm believer of reside and allow reside!!!!!!!!!!!!!!
An automotive water pump consists of a steel shaft with an impeller (like a steamboat paddle wheel) on one end and a pulley flange on the other. The shaft spins on bearings located in a cast iron or aluminum housing. The housing has internal passages to allow the water to enter the impeller cavity and exit, often to a tube like structure (part of the housing casting) to which one of the rubber radiator hoses attaches. How it works is simple. Water present in the impeller cavity is confined and pushed to the outlet by the rotating vanes of the impeller. The rotation of the pump is usually driven by a belt powered by a pulley on the engine which turns a second pulley mounted to the pumps pulley flange. The characteristics might include things like, is the pump self priming or is it self lubricating? In an automotive system the answer to both questions is yes. To evaluate a pumps efficiency you would want to set up a test rig where you attach the pumps outlet to a long hose and use it to fill a calibrated container (one gallon, five gallons etc). Then with a stopwatch you can either time how long it takes to fill a gallon container or you can measure the volume of water pumped in a minute. Either way you will get useful information you can use to evaluate the pumps efficiency. You should repeat the above test at different engine RPM's to discover if the pump has peak efficiency (or lack of efficiency) at a particular RPM or range of RPM's. Finally, if you do this experiment for real be sure you add water as fast as you pump it out so you don't over heat the engine and damage it. Have fun.
you can ask the question to a motor company
any liquid cooled Car has a water pump...... so the Whole thing is bieng used.
