Q:Can I charge the battery (1.2Vx2) with the suction tube submerged in the water or do I have to remove the suction tube every time I have to charge the battery?

Since you don't mention the model of the pump, if you can connect the charger with a dry connection, you should not have to remove the pump/tube. If you have to take the battery out, you stand the risk of dropping it in the water putting it back, but obviously (I think) you don't have to remove the pump/tube.

Q:I have gotten oil in my coolant, and coolant in my oil..It might be the head gasket, no doubt, but many people said (online forums) that my bike, has issues with the seal that is separating oil pump from water pump. They go bad, and when they do, the oil mixes with coolant and vise versa. Now, I am seeking from professional help, on how to take out both of the pumps, without messing up timing, and also without messing up anything else. I have removed the entire exhaust system, dropped the oil pan, and i can see the oil/water pump pretty good. What i do not know is how to remove it properly. Any help is help, I have searched and searched on google and forums on how to perform this task, but couldnt find any specific help on how to remove the pump. Thank you!!!!!

Q:A pump is said to be capable of pumping water up to 100 meters, but I don't want to confirm that by actually putting up a very long pipe to that height. I know that pressure is related to height, so putting pressure at the output end of the pump would simulate different heights. Any suggestions how I can rig a contraption to do this? Thanks.

Install a pressure gauge at the pumps diischarge line and note that p=wh. H =p/w, H =p{(144)/62.4}/3.28 meters Pressure expected therefore in psi, is p={62.4/144}3.28 p=14.9 psi A pressure gauge of 0 to 50 psig range would be sufficient to indicate the expected pressure.

Q:I have 2000 ford ranger v6 3.0 I replaced the water pump ten months ago and all of a sudden it's running hot it only runs hot when I stop for a second at a red light or stop sign. I changed the radiator today but still is running hot. The top radiato hose going to the thermostat housing is building a lot of pressure and the water is bubbling in the reservoir what could be wrong? And I took the thermostat out last week

You're looking for an answer that may be hard to find. Have to assume the water pump and radiator are good. But there's a lot more to the cooling system. You could have one or more issues. For one, we don't know how well the water pump is spinning or if you changed the pulley so it's spinning slower. You have coolant channels in the block that go through the head gasket into the head. In a 12-year-old car, these channels could be partially blocked with crud and sludge. Stop buying parts and take your car to a good radiator shop. Possibly all you need is a good chemical flush to get rid of the sludge. For starters, turn on the heater which might keep the temperature in the operating range, but get some help from a radiator shop. ... Good luck!!

Q:I just got a new boat with a diesel engine and I don't understand why there is a coolant tank as well as a water pump? I think the water pump goes to the heat exchanger but what actually cools the motor - how does this stuff work?

Coolant can leak from plenty of areas. Without figuring out what style of motor you've got, can handiest bet. Hopefully it's not a cracked cylinder head. But if you'll see spraying out you have got to convey the automobile to a mechanic. Obviously you're going to run out of coolant quickly even though you preserve topping it off. And it is going to occur on the incorrect time and situation. The leak price will broaden because the motor heats up and expands.

Q:When did the pump start?

The promotion of water is very important to human life and production. There are various ancient water appliances, such as Egypt's chain pump (seventeenth Century BC), China shadoof (seventeenth Century BC), Burton (Eleventh Century BC) and water (first Century ad). The famous spiral rods invented by Archimedes in the third Century BC can lift water to a few meters in a steady and continuous way, and the principle is still used by modern screw pumps.In 200 BC, the ancient Greek fire pump craftsmen invented by Kurt Siby Lucius is a kind of piston pump has the most original, the main components of a typical piston pump piston pump, but only after the steam engine was developed rapidly.1840~1850 years, the United States invented Worthington pump cylinder and steam cylinder opposite, the direct impact of the piston pump, marking the formation of modern piston pumps. Nineteenth Century was the climax of the development of piston pumps, which were already used in a variety of machines, such as water presses. However, with the rapid increase in water demand, from 1920s, the piston pumps with low speed and large flow were gradually replaced by high-speed centrifugal pumps and rotary pumps. But in the field of high pressure and small flow, reciprocating pump still occupies the main position, especially diaphragm pump and plunger pump have their own advantages and are used more and more.

Q:Yesterday my car was making squeaky noises in the front and then the fan came on FULL FORCE it sounded lik an airplane. It then started to over heat. I looked to see if there was any antifreeze/coolant in it and it was BONE DRY. I found out the water pump is bad. My boyfriend wants to change it himself but he doesn't know if where it is located is so complex he should take it to a mechanic. He has changed water pumps before. If you know anything about this.. your advice is very much appreciated!!

Water pumps arent too bad to change. Just follow the hoses to the pump, should be connected to the sepentine belt. Your diagnosis seems to be correct,

Q:i replace all the seals on the water pump reinstalled it and the same thing happened... it leaks out the bottom some where and run down the water pump and down the hot side radiator hose... any ideas?

you reinstalled the old pump? most water pump area leaks are the water pump itself. it will have a small hole located near where the lower hose hooks up, that hole is called the weep hole. when a pump begins failing it begins weeping. a water pump for that vehicle is only about $30. so cheap you should never even think of reusing the old pump if you remove it for any reason. you'll need to replace teh gasket, again, and you'll want to use blue rtv high temp silicone lightly on the gasket.

Q:Do you need a stop valve for the pump at home?

Must be connected, in the low-end water pipe, the valve is also called the bottom valve is to prevent the intrusion of water, at the same time, but also to ensure the pump again next time when starting the pump and piping in enough water to prevent idling.

Q:About how to calculate the pump installation height?

See the design manual, town water, volume P312This formula is: NPSHA = HgHzhsZs > NPSHRAccording to the actual installation of NPSHA pump cavitation can provideThe pump NPSH provides NPSHR pump samplesAtmospheric pressure Hg pump installation siteHz liquid under certain temperature saturated steam pressure.The head loss of water pipe HsThe installation height of ZsIt is worth pointing out that, with regard to Hz, with temperature related, and some problems are not given temperature, and that value is also very small, in the calculation should be able to ignore (0 degrees C, 0.06mH2O).And atmospheric pressure, we usually use 10mH2O, in fact, and altitude also related. When the altitude is 0, it is 10.3
