Q: okay i just put a new camshaft in my truck and before my water pump seemed to work but it leaked a little bit but my truck never got hot well i drove it a little bit after puting in the new camshaft and the top radiator hose and heater hose was warm but the bottom radiator hose was cold so i think my water pump went out but not to sure thanks to any answers: when your water pump goes out, either it will leak from the weep holes which are the holes drilled in the pump by the manufacturer or around the pulley. If that is happening then its your pump. The other thing to check would be your thermostat, check this by turning your truck on and leaving the lid of the radiator. check the temperature of the water in the radiator with your finger if it warms up in ten minutes then its not your thermostat, if the water level goes down ( like lack of water) then its the pump.

Q: Relationship between power and flow of sewage pumpFor example, how much power waste water pumps do 1m3/h and 100m3/h need?Best detailed listShow the relationship between power and flow: If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.

Q: So I need to make a human powered water pump... Does anyone know how to make one? Any websites that could show me would be nice.MORE DETAILS:The pump is on the ground...it needs to pump water from a reservoir into another reservoir that is two meters high and two metres across from where the pump is... The pump needs to be handheld too. What should I use and any good plans on how to make it?: The simplest manual pump is the lever-arm pump. This is just an elongated cylindrical reservoir, a valve casing, and a pump chamber in a linear arrangement. A piston within the pump chamber is connected to a link, and a handle which is used to pump the water. You can make a simple one by converting an ordinary bicycle pump. Attach an input hose to the air inlet, and an output hose to the pressurized air output for the tire. A good way to develop plans on how to make it would be to visit your local sporting shop or auto parts shop and look over their pumps. .

Q: What is the function of a submersible pump?: Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.

Q: Van died on the road. It wants to turn over, but it won't start. I had it towed to Firestone. They're telling me that it needs a whole list of stuff. I ask them, quot;What does it need to just get it running?They say, quot;A new timing belt, water pump, thermostat, and coolant flush.quot;If the timing belt is indeed broken, I know that it will need to be replaced. And, probably the water pump, too. But, what is the importance of the thermostat and coolant flush? Will the car not run if I don't have a thermostat? Can't I just put Engine Coolant in and not have to quot;flushwhatever is supposed to be flushed?Thank you in advance for your help.: It sounds to me like the water pump broke apart, and destroyed the timing belt. The thermostat has wax inside it to control when it opens and closes, so if it overheated there's a good chance the wax leaked out, and the thermostat will no longer open when it should, causing further overheating. As for the flush, they probably want to make sure there are no broken pieces of water pump in there that will cause further damage. As for having your vehicle serviced by Firestone. Ugh:-( I too would be worried about valve to piston contact when the belt broke, but I'm not sure offhand if that's an interference engine or not. I do however know (slightly off topic), from my time as a Dodge tech, that they had a silent recall on the 3.0L heads: If they happened to have them off for any reason, they would cut a small groove in the top of the valve guides with a special tool, and install a snap ring to prevent the guides from sliding down into the runners.

Q: Ok, simple question, on a 1992 Jeep Cherokee 4.0. The water pump sucks water (not push) through the heater core correct? So the flow of water goes from the block, through the heater core, into the water pump, right?: Your water pump pulls cool water from the radiator and pumps into the block. If by heater core you mean the heat inside you jeep I believe it pumps thru the radiator. if you have a automatic transmission sometime it cools thru the radiator. I don't know that much about how jeeps work they might be connected different but the way I described is the usual way on most models.

Q: A water pump that consume 2kW of electric power when operating is claimedto take in water from a lake and pump it to a pool whose free surface is 30 m above the free surface of the lake at a rate of 50 L/s. Determine if this claim is reasonable.You have to show the minimum power required is 14.7 kWand i can't get it.: A liter of water mas a mass of 1Kg. How much work must be done to raise 50 Kg of water through a height of 30 m? You can say: Work done (W) = potential energy gained (mgh), Or you can say that Work done is the weight force (mg) * the distance moved against the force (h) Either way, W = m * g * h where m is the mass; g is the acceleration due to gravity {9.8 m/s?}; h is the height W = 50 * 9.8 * 30 = 14700 J If you need to do that amount of work in one second, that's a rate of working of 14700 J/s A joule/second is a watt. Minimum power required = 14700 W = 14.7 kW

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!!!!!: Most okorder for a good schematic of your oil pump and water pump assembly

Q: OK so i am new to RVing....I have an older 1971 trailer pull forester....It has a your normal fresh water inlet on the outside of the trailer, fresh water tank, and water pump. My question is actual a double part question #1 When i screw the hose on the inlet and start filling the water tank i hear it going in but i still have no water coming out the faucet...Does this have to do with the water pump? why am not getting water to anything except i hear the tank filling up?!?#2 Is the Water pump A/C or D/C......I have that little pull knob (that i guess turns it on or off) and i was curious if i needed to be hooked up to the Battery in front to make this work? or should it work with the regular AC that everything else is working on?Thanks for any help: I am not completely sure but i'll share my thoughts. I'm not certain but I think the water tank should have a seperate fill up. If your filling your fresh water tank and nothing is coming out of your faucet, my guess would be the water pump. Check and see if there is a reset button on your water pump switch. If not there should be a breaker for it located somewhere in the camper. But if you screw your water hose in to your camper and there is constant water pressure then there should be some water without having to use the water pump. If not then I'm stumped..

Q: I have septic tanks. My toilet flushing water is filthy and the water pump runs for a long time and sounds strange. I have turned the pump off for now but know this is not an answer but i was worried it would burn out or something. Do i need a part for the pressure pump? Please help any plumbers out there.: I'm not sure why you only mention the water in your toilet. Alot of residential wells are just holes in the ground with 10 or 20 feet of casing. That is the large pipe in the ground that keeps the surface dirt from caving in. If the pump pipe- the one that the water comes out of the well in- has a hole in it down below the casing, then when the pump runs water sprays out onto the dirt in the well and is sucked up by the pump. Sometimes the dirt hole will collapse filling the well to a level close to the pump or even above. Dirt in well water should be checked out by a pump company soon. Your pump will wearout faster and if there is a chance of cleaning out the dirt it should be done right away.
