Q:A total of three units, usually starting two units. After jumping the gate, it was like this. I haven't paid attention before. Is it a turn around?

The water pump with frequency conversion is set correctly and will not burn the motor. If there is a problem, the frequency converter will automatically stop running. The frequency converter can change the positive and negative (frequency changer without this function, change the phase sequence)

Q:I want to run 1 HP, 220 v, single phase water pump on solar panels without using any batteries. what do I need to do so amp; how do I wire it?

Does a great job of increasing global warming as well, as the waste energy becomes what = HEAT!

Q:My Toyota 2006 Sienna has 80K miles on it and I asked the dealer to inspect the vehicle. He suggested that i replace Timing Belt, Water Pump, Drive Belt and Trans Pan Gasket. The cost of the repair comes to $1300 ($460 for Timing Belt, $350 for Water Pump, $140 for Drive Belt $370 for Pan Gasket).I'm caught by surprise with the price quoted and things to be replaced. Is the price quoted reasonable? Are these replacement common for Sienna vehicle with 80K miles? I don't know what could possibly go wrong if these are not changed for couple of months. I have an extended warranty on the vehicle for 100K miles will any of the above get covered under warranty?Any suggestions or advice is highly appreciated/

Q:My father in law has a 95 jeep grand cherokee with the v~8 engine, the water pump started leaking so we went to autozone and bought a brand new duralast one with new gaskets, I'm gonna be putting it in when the weather lets me since i have to do it out on the street in front of the house, i was just wondering if anyone on here had any tips for me since i have never done one, I'm not a mechanic but i work on all my own vehicles since i am too poor to take them to a shop, i know a lot more about cars than he does so he asked me to help, it didn't look to hard but i'm not quite sure what im getting myself into, any advice or tips about this job is greatly appreciated. And please don't post telling me to take it to a mechanic as this is not a option for us, i will get it done i just thought somebody could help make it go a lil smoother with some pointers... Thanks

Remove the fan blades/radiator shroud. That will give you more room and you can see better. Remove the belts and pulley from the water pump. then remove the clamps/hoses. After that it should be a simple unbolt. Be sure to clean all the old gasket off the block and use a silicone gasket sealer or the equivalent to hold the new gasket to the pump during installation. Start all bolts before tightening any of them and then tighten them carefully so that the new pump seats properly and you don't crack the new pump.

Q:Does it take more power to pump water with a 1 /12 hp bg motor/pump than one that is a spare pump/motor running dry,not connected to the system? I am trying to figure out how long it will run with an power inverter during a power failure.

Hi there, Your 1/12 HP motor will draw 0.52 amps at 110 volts from the inverter. It would draw about 5 or 6 amps from the 12 volt battery to produce the 0.52 amps from the inverter. You need to know the amp-hour rating on your battery then divide that number by 5-6 to get an approximate time the pump would operate on backup. Yes a pump that is pumping water will draw considerable more power than a pump that is pumping 'dry'. The best way to check is to just try your setup and see how long it lasts (before it's needed) since there are inefficiencies in the inverter, voltage drop in the wiring and perhaps the backup battery is not new. Manufacturers always are optimistic with their ratings Short answer: try it out before you really need it then you will know for sure. Hope this helps, Al

Q:The actual way to move water (liquid) from a pond with small bits of debris. Trying to find out which system is the most efficient: vane, impeller, rotary, centrifugal...etc...either by hand or using a bicycle to turn the pump. I do NOT want to use an engine or electric motor. I've read about the transfer pumps in the hardware store are only about 50% efficient, I need something better that will provide me a continuous output. Something lightweight that will handle pressure. Any ideas? Thanks in advance!!

Although you may not think of it as a continuous source, an ancient Noria water wheel is quite effective and can be leveraged with gears and ratchets. The continuous flow is acheived by transferring the water to a reservoir at a higher elevation from which the water at a constant known pressure determined by the elevation can be drawn, excess water can be overflowed, regulating the pressure so long as the draw is less than the average delivery of water. Early mines were cleared of water with Norias as pumps could not pull beyond atmospheric pressure.

Q:I have an 8 gpm pump at a depth of 170 ft, I am pumping the water 2000 ft in a 1 1/4 inch line. I need to know how many gallons per minute I am getting.

Use the Bernoulli equation, aka mechanical energy balance.

Q:does anyone know how a water pump works????????????

Water pumps are available in different types. 1. Centrifugal type: Operate by increasing the velocity of water which, when the velocity is decreased by the Volute casing, the pressure increases. 2. Rotary Gear type.: Operate by Displacement of the water by rotating, gears that trap water between the teeth of 2 rotors of inter-meshing gears that release the water at a higher pressure on the opposite side of the pump to the intake. 3. Piston (reciprocating) type: Also a displacement operation by a piston moving backwards and forwards within a cylinder (like a hypodermic syringe in operation). Back stroke takes water into the cylinder and forward stroke discharges it at a higher pressure. (Double acting types are also used that take in and discharge alternately from both ends). If you mean the water pump of your car, they are generally of the Rotary type.

Q:Could it make coolant quot;Boilquot;? Ive heard myc ar's behavior is Normal, and most likely just heavy condenstaion as it DOES go away, also the behavior of the coolant and the tank.. but i DO know the Water Pump is quot;Weeping,or quot;Seeping,so i wonder what interaction that would have ont he Cooling side of the motor; what effects can it produce? What would i notice?My 1991 Calais 2.5L quot;Iron Duke,

Steam coming from your headlight on a rainy night is NORMAL, since the halogen bulb makes a lot of heat. This turns the water into water vapor, (steam) as it attempts to dry out. If you don't physically hear the bearings in your water pump, or watch colored fluid drip out from under your engine, then your water pump is JUST FINE!!! STOP WORRYING! I answered one of your questions the other day. If you take my advice, your engine will run at it's best. For extra protection, drain and flush your cooling system out, and use Mercedes coolant. Dex-cool has been proved to be a potentially bad coolant. READ the dexcool litigation websites. Mercedes coolant, which is YELLOW in color, will last for 150,000 miles, and is a time tested WINNER!!! Use ONLY top tier fuels (read about this on web) and use ONLY synthetic oil, like Mobil One. CLEAN your idle air control valve and throttle plate. AND STOP WORRYING!

Q:Hi, my mechanic said that I need a new water pump. I have a 1994 Dodge Caravan SE. What is involved with the whole changing of a water pump? He said it would cost about $400 to $500 for the whole job. Is that correct? Were is a good place to go get one? I live in Staten Island New York. Is sears a good place for that job? What is installed when they do this job? Belts or what??? I thank you for your time and any help is greatly appreciated. I will be taking my car in this week and will leave a best answer based on the correct information. Thanks again :-)

$400 to $500 seems a bit high...should be closer to about $300.. .. call around to a few repair shops and get some prices...this is a pretty straightforward repair for an auto shop..
