Q:How many kinds of pumps are there? What are the advantages of soft start?: The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.

Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?: The intelligent controller of water pump is full of water and automatically shows the shortage of water in the lower pool. The reason is that the sensor is out of order or the line is out of contact. First of all, make sure that the upper limit of your controller is normally open or normally closed. When the upper limit is reached, does this point change? If the original upper limit position is normally open, check the switch and pump insulation.A pump is used to increase the pressure of a liquid or gas, the flow conveying machinery, and "jump" or "flow" is a homonym, is a transliteration of the English pump, is a device used to move liquids, gases or special fluid medium, which is reactive to the fluid machinery. The heart of man and animal can be said to be a natural pump, which carries blood to all parts of the body.

Q:How do I replace the water pump on a 1996 Mercury 200 hp outboard engine? I have the parts, but want to make sure I replace it correctly. Thanks!: I strongly suggest that you purchase the Bible at a local outboard shop, it has exploded views and good directions, as well as tips, even if you don't know a lot about engine's it will educate you about YOUR engine, just thumb through it, the water pump change out directions are very good !

Q:My water pump is losing pressure slowly even though no water is being used. Your help is appreciated. Thank you.: If the motor sounds louder than normal. Youll need to check the impeller in the pump. Make sure the shaft seal on the pump is not leaking. You either have a leak, restriction in the system or a bad impeller or failing pump motor.

Q:If you use a water pump to move water through a circular trench, essentially making a little river, and then place some kind of turbine or water wheel or something to generate electricity from the moving water, couldn't you use the electricity generated by the turbine to power the pump, thus requiring no outside power?: All the energy that you can get from the stream you have created will always be less than the one you are using to drive the pump that feeds the stream. In engineering field you must get into your brain that Perpetual. motion machines just does not exist. you can use it to understant thermodynamics processes when using in simulated problems but it is only ideal situations.

Q:A 0.13hp electric motor on a water well pumps water from 30.23m below the surface. The density of water is 1.0 kg/liter. How many kg of water does the motor pump in 2.20hr?: It is known that 1 hp = 746 watts, so 0.13 hp = 97 watts = 97 Joules/s The amount of work to lift 1 kg water a vertical distance = 30.23 m = mgh mgh = (1)(9.81)(30.23) = 296.6 J no. of seconds in 2.20 hr = (2.2)(3600) = 7920 s total work output of a 0.13 hp pump in 2.2 hr if 100% efficient = (7920)(97) = 768,240 J no of kg lifted by 100% efficient pump/motor in 2.2 hr = 768,240/296.6 = 2590 kg ANS

Q:can't get the pulleys to line up I know I have a mid 70's 400 and the water pump is later than 1969 but I can't find a pulley that works every one is about a half inch off I bought a aftermarket set of underdrive pulley's from march performance and still the same problem the water pump is a half inch off there was no long or short water pump right they are all the same lenght right??? The only difference I know of is that pre 1968 the pumps have a 8 bolt design and after they have a 11 bolt design is that right???: Actually there was two main pumps for the older ones,, one was called a short shaft,,and one was called a long shaft,,the long shaft was the most popular,and it all depends on whether your car had power steering,,and air conditioning on it,,all the ones that used the long shaft usually had air,,and power steering on them also,,also some of them had a smog pump on them,,this was the main reason they used the long shaft,,most of the smog pumps got taken off and discarded down through the years,,but you still had to use the pump that had the long shaft,,this is the problem your having,,i own a repair shop in Tennessee,,and have been redoing some old cars in the past few years i to have run across the same problem you are having,,you can have a long shaft ordered for you ,,and it will work fine,,i had to use the long shaft on the one i was redoing hope this helps some.

Q:I was looking at a water pump and the specs said 110 Foot Max. Total Head and 20 Foot Max. Suction Lift. Can someone please explain this? Thanks.: I have two ponds, one that is always full and one that is always low. They are 550 ft apart and there is a change in upward elevation of about 35ft. What pump is needed to allow me to transfer water from the lower pond to the upper pond?

Q:What's the difference between a cold water pump and a hot water pump?: Cold water pump is generally packing seal, hot water pump is generally mechanical seal. If the cold water pump is used to transport hot water, the common trouble is that the shaft seal is easy to leak and the water pump is easy to damage. Generally in the design of building water supply and drainage, cold water pump and hot water pump can be selected according to the cold and hot water. Water supply and drainage design manual (common equipment) and pump manufacturers Water Pump samples can be found.

Q:I have a 1997 mazda 626 4cylinder. For a while now, my hot n cold gauge keeps wobbling back and forth. I was keeping water in it and it was fine. A week ago it went all the way to hot and started smoking. There is water gushing out right beside the pulleys. I'm not sure if it is the water pump or not. Now, my car won't crank. Someone told me that it was the rotor button, but i can't tell if it is bad. I don't really want to take it to a mechanic. Can someone help me?????: I am not a mechanic, but I can tell you that I just got my car back this morning from a mechanic because I had an almost identical problem. I had a slow fluid leak for a couple days, and steam would come out from under hood when I parked (after only driving for 10 minutes). Four days into this I went to the pharmacy and when I left I noticed I left a very rusty puddle of water in the parking lot. On the way home temp was running higher than normal. Let the car sit until a mechanic picked it up. Something happened with the timing belt and it caused problems with the water pump and coolant got in my oil. Had to have an oil change, coolant flush, water pump replaced, and a timing cover/gasket/seal something or other. $400 later I am up and running, good as new. Hope this helps and I hope you can find a good mechanic like I did.
