Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
The wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious.
Q:was putting a water pump on, and i tight too much on 2 bolts, and they broke. is it anyway to fix it ?? is it going to cost alot in labor ??
Remove the water pump. Then you should be able to grab whats left of the bolts with a pair of vise grips and turn them out.
Q:If you use a water pump to move water through a circular trench, essentially making a little river, and then place some kind of turbine or water wheel or something to generate electricity from the moving water, couldn't you use the electricity generated by the turbine to power the pump, thus requiring no outside power?
All the energy that you can get from the stream you have created will always be less than the one you are using to drive the pump that feeds the stream. In engineering field you must get into your brain that Perpetual. motion machines just does not exist. you can use it to understant thermodynamics processes when using in simulated problems but it is only ideal situations.
Q:What is the 10KV pump unit?
10KV should refer to the motor start voltage value, ultra high voltage start, the general pump more than 160KW of the motor, the voltage used in 6KV, you motor should be more than 300KW

Q:There is a 5.5KW before the pump head is now 25 meters and flow of 20 cubic meters, but not up to the requirements, I think this is like with a motor pump, lift more than 20 meters, the flow is about 40 cubic meters of water pump, please inform the models and parameters, thank you
With the motor pump are pump according to the actual need of work with you in the head, under the same water doubled, the motor is certainly not enough, you should this motor pump change together in order to meet the requirements of.
Q:I have a Honda Accord, and last week I replaced the Radiotor, due to a leak. This week the Water pump broke, it was making a ver loud noise and major leak, when I opened the rad, basically all the fluid was drained.Do you think the two are related? or do you think when the Rad was replaced it was not done properly which caused the water pump to break?Thanks.
If your radiator went then it is highly likely that regular maintenance ie rad flushing, fluid changes have not been taking place. Water pump will have nothing to do with the rad, unless when rad was leaking you ran vehicle with no lubrication (water-antifreeze mix) to water pump. The pump will just seize up or crack. These issues are probably just age related. If the rad was defective or you had coolant issues, the lights on your dash would indicate low fluid engine overheat of course you wouldn't drive it then. Everybody knows what a dummy light is for, right.
Q:Hi, I'm looking for an affordable pump that can be used to circulate heated water (60 C) through a 12pipe with a diameter about the size of a pencil. Is there a pump out there to match this application? I've come across some small fountain pumps, but they need to be submerged in the 60 C water bath and I'm not sure about the temperature tolerances of it. The model I'm currently looking at is a quot;TotalPond130gph fountain pump model. Thanks
Sounds like you're in quite a predicament there.

Q:I have just replaced the timing belts on my 94 Civic Si and my 00 Elantra GLS. Both were done at different shops, but i got the same hounding to replace the water pump when doing the belt. My Elantra has 66k and my Civic 85k and i know how important the timing belt is-especially with a negative clearance engine like the VTEC. previously, i've never been told to replace the waterpump with the timing belt til now. is this just a ruse to extort more money out of me, or is there some validity in what the guy behind the counter is saying??
First, what determined the need for the timing belt? If it's due to be changed as part of the regular maintenance schedule, fine. And why do you need a fuel pump? If the car runs fine as it is, I would question that. The fuel pump is usually located in the fuel tank which can be a pain to replace, so I'm not sure that that total cost is comparatively unreasonable. BTW, when replacing the timing belt, it's usually recommended you replace the water pump at the same time, as it's located right there, and may prevent having to do the same labor again between belt replacements. You can also call various other shops in your area and get an estimate of what they would charge for the same service. Also, you can use the link provided to find a mechanic in your area who has good reviews recommendations from customers. Look for 'Find a Mechanic and enter your zip code for the info...(You may want to check out the whole site, for fun and car info)... Hope that helps! EDIT: Yes at 110k it should be due for the T-belt/water pump, now it's just shopping the deal!
