Q:What does the pump lift mean?
The pump head is the parameter you must know when you buy a pump, that is, the height of the pump.To buy a pump, I think the Heathrow pump is OK. I bought it earlier this year. It's not bad yet, but the quality is pretty good.
Q:I know that the water pump is belt driven, so it would be easy to connect it to my bicycle. What I am wondering is if I can pedal fast enough to make it work. Does anyone know how fast I would need to pedal to operate the pump?
Mechanical water pumps will move water with any rotation, provided it's a sealed system and there are no obstructions. The flow rate will be determined by the RPM of the water pump. This is proportional to the pulley sizes of the drive pulley to the water pump pulley. 600 RPM for a water pump at idle is sufficient for the cooling system design and the engine heat load at idle. Without knowing the specifics of your application, it would be hard to tell how fast you would need to pedal.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
The flow rate is 70 cubic meters per hour. The head is 35 meters, and the SH type double suction centrifugal pump is adopted.Double suction centrifugal pump for conveying liquid water or similar physical and chemical properties of water, according to the needs of users, by changing the pump structure and the material can be used for transport of muddy sand or various corrosive liquids, this series of pumps are suitable for factories, mines, city water supply and drainage, power plants, farmland irrigation and water conservancy.
Q:I installed a circulating pump in the far bathroom, since the length to the water heater made for a long wait. It takes 25 seconds for the hot water to arrive, which means 25 seconds of hot water wasted, once the water is shut off.Is it cheaper to, selectively(2 settings on timer) run the pump, or just wait on the hot water? And without the consideration, that time equals money. I imagine the more people that use it, the more efficient it gets.
In commercial applications it means hot water is there waiting on you rather than the other way around. It saves on lost time and water. In home use I would install a timer so pump runs only when it is needed.Insulation on the pipes will also lower the load on the hot water heater. So you can save time and money.
Q:What are the parameters of the pump price?
With the flow and head related, the greater the flow rate, the higher the head, the greater the power, the higher the price.
Q:Hi I really need a USB water pump (small). I have found one in China but they need payment in a different currency so its proving difficult. I would much prefer a US/EUROPE seller. Cheers.PSgt; If I had to pay to get the power supply changed from wire to USB then I could if anyone knows who could do this.
The USB output has a 5V power supply. USB2 delivers up to 500mA and later versions may be 900mA. USB hubs start off with less than this (100mA) but change as they are initialised. Some dedicated USB charging ports supply up to 1.8A. There are some USB power cables that take the output from 2 ports in a sort of Y harness (first link for example). The result of all this is that only a very small pump would run from most USB ports. I did find 2 rated at 5W and 8W but the voltage was not shown. I suspect they were mains operation, meant for large water bottles. If they were 5V they would use 1A and 1.6A respectively, so only run from special USB charge points or double cables, and only in some cases anyway. I assume you want to run from a Laptop/Notebook battery for convenience. The point is that even if the USB port can supply the correct voltage and current the battery would be emptied very quickly. It is probably cheaper to get a suitable pump, then power it from a separate and more suitable rechargeable battery or mains adaptor (wall wart), whatever it takes, taking into account how long it should run with a single charge. This is about the battery voltage and the capacity in ampere hours - the number of hours it can supply a given current. D size rechargeable (Ni-MH) would run a 6V x 6W motor using 1A for about 6 hours. C size cells are half that, and AA cells about half again. It takes 4 cells to get 5V. Get them as a pack though or at least with a battery holder, as they cannot be soldered. Then you need a proper charger. Recent laptop/notebook batteries are lithium ion types, 10.8V and 4.8Ah, so deliver 1A @10.8V for 4h more or less. Other types worth considering are for cordless drills.
Q:When we turn our water on in the house it will run for a while and then shut off.. It has been coming back on after 5 0r 6 mins.it used to do this about once a week but now it does it every day we don't mess with any breakers because they don't get triped . We are on well and this well is about 7 yrs old anyone have an idea what could be the problem .. If any more info is needed I can reply..
Your bladder tank is water logged, you will need to drain the holding tank and refill then check pressure, you will probably have to add air to the tank. There will be a shrader valve (the same kind of valve on your vehicle tire, use a tire gauge) near the top of your tank. Check the pressure first, if the pressure is low(there is a tag telling you what the pressure should be) you will probably have water at the Shrader valve. Very common where soil is sandy.
Q:i replaced the water pump and redid the timing belt. now when i start it, it sounds like one of the cylinder is misfiring and makes a chucking noise. do you have to reconnect everything together to see if thats the problem? the engine worked fine before i replaced my water pump. engine like vibrates at each chucking noise. could it be incorrect timing even when the engine starts fine? or is one of the valves bent which is causing the vibration and noise? i checked teh spark plugs and they are fine could if be bad coils? or is the crankshaft weared out? please help and thanks for you help about my situation.
sounds like the timing is off a little, yes, even with the timing set incorrestly, it can still start and run. I doubt your vehicle has coils and there is no such thing as weared.
Q:The water pump needs to be replaced but now it is taking several attempts to start the car.
How can this simple question evolve into the previous nine answers? The water pump is belt driven and mounted on the front of the engine. The starter is electrically powered and drives the ring gear on the flywheel to start the engine. One has nothing to do with the other mechanically. Hard starting can have a hundred different causes, but keep in mind the starter's only function is to spin the motor over at a certain speed. Now for the answer..... The worn water pump is allowing the alternator belt to slip and the battery is not getting fully charged. The engine does not spin over at the desired speed and the engine gets hard to start.
Q:Water is leaking from the front of my car, on the right where the radiator is located. only thing is that its not leaking a lot, just a little.... but people keep telling me that my timing belt is going to go out and that i will be stranded!. i will like to know the cost of both the water pump and timing belts for my 2001 PT Cruiser please.
A suggestion. If your car is around 70,000 to 100,000 miles then you should change the timing belt. If it breaks, it will leave you stranded, and cost you more because the engine may be damaged. (girlfriend ignored the warning and it cost her $1000 in engine parts - I was the free labor!) Because the timing belt runs the water pump, most mechanics recommend changing the water pump at the same time, the water pump does not cost that much more. Parts and labor for this cost about $700 to $1000, sometimes it costs a bit more because the idler pulley is worn and must be replaced also. As for your leak, it would be best to have the cooling system pressure tested to find the spot of the leak. If its sometime other than the water pump, you'll be glad you found it early. Good luck.
