Q:I am trying to replace my old water pump with a new one. I have the quot;special tooland everything but i just cant get the water pump to come loose at all. Any suggestions would be helpful Thanks: When you mean it wont come loose, do you mean you cant break the bolts loose or is the pump stuck on the motor like glue? If the bolts are stuck, try spray them with penetrating oil and let it work in for about 30 mins. If the pump is stuck, use a narrow putty knif, gently tap in between the pump and the block, and pry it off, then clean the mating surface completely to ensure the new pump seals properly.

Q:Earlier today I was driving and my car shut off at a stop sign. I got it to start again and it shut off at the next stop sign, so after a few minutes I got it to start again and immediately pulled over as there was a small amount of smoke coming from under my hood. The temp gauge didn't say it was overheating, but I think it mightve been stuck, because that had to be what happened. After sitting there for a while it started and stayed that way for a while, I let the engine run. I drove it to the gas station and put some coolant directly in the radiator and the resevoir, and almost all of it leaked right out. I started to drive it home and had to pull over about 6 times to let it cool down because it kept overheating( temp gauge showed it this time). I think its the water pump that is leaking, but I know very little about cars, and was wondering if it could be anything else? Also, the heater wasn't working in the car today at all.: This Site Might Help You. RE: water pump leaking? 99 dodge neon? Earlier today I was driving and my car shut off at a stop sign. I got it to start again and it shut off at the next stop sign, so after a few minutes I got it to start again and immediately pulled over as there was a small amount of smoke coming from under my hood. The temp gauge didn't say it...

Q:We had to have our well pump replaced yesterday, how long before the well settles down, and the water tastes like it used to?The company who replaced the pump told us when changing a pump it disturbs the well, and it would take time for everything to settle back into place. Thank you in advance for any and all suggestions.: I had my pump changed and the water remained the same. It looks like you didn't really need a new pump, but a new screen on the well itself. Ask a well company what they think. I thought it was my pump, too, until I found out they had to change the points in my well to the tune of $1,000. Changing the pump should have never changed the well....sounds like you hired a plumber.... Good Luck!

Q:I would like to know that a water pump or water motor which is of 1 hp what is the height from which it can pull water ? And also if there is a bubbling sound of air and no water is being supplied what does it mean ?: I will 'clarify' the question, then respond----- If you have a 1HP motor connected to a water pump,; what is its lifting capability ? (like raising the water UP from a well)... At or neat 'sea level', the very ideal (perfect) pump can lift water UP from 33 feet below. To be practical, considering in-efficiencies(losses) you should plan for about 25 feet of lift. Gurgling or bubbling of air/water is a good sign that the pump can not generate the vaccum-seal to begin the flow of water(priming process). You need to provide a way to prime the pump. To prime the pump, you need to supply a flow of water INTO the pump as it is running(water must be running backward into the well, then the pump will initiate the lifting process. To prevent the need to prime the pump everytime that you turn it on, you should put a check valve at the INTAKE orifice (the very end that sticks in the well). This will hold the column of water in the pipe; preventing it from running back into the well. (A check valve allows fluid to flow in one direction only....this must be connected such that the water can only flow UPWARD, out of the well. Good luck.....if you need further assistance, do email with more pump detail/specs. Make sure that the pump is rotating in the correct direction......

Q:implementation of regulator in water level control system: This might be explained with an example. There is a water tank being used by a community (or a dwelling) and it is supplied by a pump from a well. There is a switch in the tank that is wired to the pump motor. The switch is activated by a lever attached to a float in the tank. When the float is in the down position the pump runs, When the float is pushed up by the water the punp is turned off. The pump first operates and fills the tank and then shuts off when the tank is full. When the usage of water drops the water in the tank to a certain level, the pump turns on until it is full again. The float, the switch and the motor are the pump regulating devices. This type of regulation is called two-position, like a light switch. Other more involved types of regulation may adjust a valve in the pipeline from the pump . This changes the rate of flow while the pump continues to run. The first type of regulation can be called digital because the flow is yes or no. The second can be called analog because while it is on, the flow varies in amount. If I have not adequately answered your question, maybe someone else will.

Q:What's the submersible pump?: Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage. Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.

Q:how often do i need to change a timing belt and water pump on my car? also, how much should it cost? should i have it done at the dealers or at a small mechanic shop if i chose to? which would be best? what are steps when having timing belt change?: If it's Japanese, every 90,000 miles. If American, every 60,000 miles. Just recently changed belt and water pump on my Honda for $400 at an independent. Dealer is more expensive.

Q:The role of impeller in water pump: The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.

Q:ok some one put sugar in my gas tank i had to replace my fuel pump and now i have sludge that's eating th inside of my radiator hoses and my water pump went and of course that's timing driven and my timing belt is awful tight i cant put a finger in between it ....and my car is not car water so i cant drive it and i don't have money to blow to take it to a shop any help u can offer will help and i know i am going to replace my water pump and info for when i do that will help and answers to the sludge (its like a Vaseline) and how to find out if its in my motor or my brand new radiator ? me plz i am a 18 yr old girl with knowledge about cars and have friends to help me and my mom so any helpp will help and is better then none: If okorder /.. Anyway I hope you have better luck, i'd kill someone if they put sugar in my gas tank. Then again i have a locking gas cap. If you have any questions feel free to im me via yahoo messenger.

Q:There is a pump, the rated power is 1200W, but only more than 600 W measured!What's the matter, please?I was not measuring no-load, pumping water in the pool, this work environment should be sufficient to pump full load?Also, is the rated power should not change?Thank you: We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
