Q:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:Urgently need USB water pump please?
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:Sim City for iPhone, help! Water Pumps?
Depends on the version. Older versions of Sim City you just hook up power to it and make sure it is next to a water source. In more recent versions there is a desalination plant if I recall. Put it next to the salt water then it works. Make sure the plant is right next to the water source because if it is even one block away it won't work. I learned that by mistake. If it is RIGHT NEXT to the water then the source may be too small. You have to try out various combinations depending on the version. One thing though is do not put a regular water plant next to ocean because it won't work.
Q:Integral Problem: Water is pumped out of a holding tank at a rate of 4-4e^-.14t liters/minute?
Water is pumped out of a holding tank at a rate of 4-4e^(-.14t) liters/minute. Lets call that function w(t). So if we integrate w(t) over a time period that will give us the total water removed over that time period. So lets integrate it from t=0 (time when pump started) to t=60 (one hour later): ∫ w(t) from t=0 to t=60 ∫ w(t)=∫ 4-4e^(-.14t)=4t+(4/.14)e^(-.14t) evaluated from 0 to 60 ∫ w(t)=4(60)+(4/.14)e^(-.14*60)-4(0)-(4/.1... ∫ w(t)=211.435 liters removed If the holding tank began at 1000 liters and 211.435 were removed... Remaining water=1000-211.435 ***Remaining water=788.565 liters***
Q:how much does a 96 neon water pump cost?
actual its 150 around...u may get someone to do it for 400 to 500... water damage on the belts LOL,,,every time u go through a puddle they get water on them
Q:water pump or not? need clarification before i spend more money?
Have the system pressure checked that will show U where the leak is.
Q:Power flow conversion of water pump
Pump shaft power (kw) = water supply (L / s) x lift (m) /102 * efficiency = flow * lift * density * acceleration of gravity.Explanation:102 is the unit collation constant.Pump effective power / pump shaft power = pump efficiency (general 50%--90%, large pump higher)Unit time pump liquid volume flow is, flow by Q, a unit of measure: m3 / h (m3/h), L / S (l/s), L/s=3.6 m3/h=0.06 m3/min=60L/minG=Q G refers to weight - liquid proportionThe energy obtained by pumping a liquid of a unit weight is called a lift. The pump head, including suction stroke, is approximately the difference between the pump outlet and inlet pressure. The lift is expressed in H, and the unit is m.The efficiency of a pump is the ratio of the effective power to the axial power of the pump. ETA =Pe/P pump power usually refers to the input power, the motive power to the pump shaft, it is also called the shaft power, denoted by P. Effective power is the product of pump head and mass flow and gravity acceleration
Q:My circuit breaker for my water pump is wet and pops? What should I do?
I am assuming that the breaker for your water pump is in a disconnect box on the exterior of your house. If the disconnect is wired to code the disconnect would be fed with a line that also has breaker in your main panel. If this is the case the first thing you should do is identify this breaker and turn it off. Don't go by any labeling on the panel. Use a tester to make sure power is completely off in the disconnect.If power is off you can then pull the breaker out and dry it off. You can also dry the enclosure with a towel. When everything is dry reinstall the breaker and turn power back on in main panel. If it still pops in disconnect, it would be wise just to buy a new breaker , they are not that expensive. Not necessary to start using cleaning sprays.This procedure should solve your problem if everything has been wired to code. If you are not sure about anything I have described, please call a professional. Good luck.
Q:Hit and Miss Engine Water Pump?
A horse and a half won't do much. You would be better off with a hydraulic ram type pump if you can get about a 10 or 15 foot fall before the ram. It will pump about 4 or 5 times the height of the fall, but in small quantities. It will run 24/7 without gasoline, so it will fill a tank over a long period of time. The railroads used them during the steam era when they had huge water towers out on the plains.
Q:im making a pond filter. need help with water pump?
1. I had an electrician put a buried cable in the ground coming up to a weatherproof post with outlets and an on-off switch. It was not as expensive as I thought it would be. 2. You can put the water pump and filters by the house or even inside and run buried water pipes out to the pond, or just put the pump inside and have the filter by the pond which would run by water pressure or gravity. 3. A windmill or solar panel. A siphon uses potential energy stored in the water to work. Once the water has dropped through the siphon, there is no more energy to draw from and the siphon stops. A windmill or solar panel could provide the power to lift the water back up and make the process continuous, or at least while it's windy or sunny. However when pricing these two options even though they would be very cool if you have the large yard to accommodate them, they turn out to cost much more than either 1. or 2. and have much higher maintenance costs associated with them. 4. If it's a very small pond, you can get a solar powered filter/fountain that looks like a floating plastic lily pad. My son had one of these, but it only worked on the sunniest of days, and lasted one summer before wearing out. If you add a large block of filter foam over the intake it may last a little longer. Rinse it out two or three times a week.
