Q: QDX is a submersible pump. What does "X" mean?: QDX is a submersible pump model, its specific meaning is:1.Q: submersible pump.2.D: single-phase power supply, three-phase electricity is not marked.3.X: pump, pump type is not marked.Complete submersible pump model will generally add rated flow, rated lift and motor power rating. For example: QDX40-8-1.5, meaning with single-phase 1.5KW motor, rated flow of 40 cubic meters / time, the rated lift of 8 meters under the pump submersible pump.According to the different relative position of pump and motor, submersible pump is divided into pump type and pump type. The pump submersible pump motor in the above, below, this structure greatly reduces the radial size of the pump, so much for submersible pump and small submersible pump operation. Submersible pump submersible pump on top of the pump in the following, it is divided into two types of internal and external type. The submersible pump carries the liquid through the annular flow passage around the motor, then cools the motor and then flows out of the pump outlet. Even though the pump is near the drain sump, there is no need to worry about the temperature rise of the motor, so the application is becoming wider and wider. External pump submersible pump directly from the pressurized water chamber after the impeller or diffuser outlet of discharged liquid, motor is cooled by liquid pumping. As the lower pump structure can work in a relatively shallow liquid, it is often used in submersible pumps for operating surfaces, especially the main structure of large caliber submersible pumps.

Q: Pump flow 6M3/H is an hour, how many tons of water?: =1 tons of water 1M3So 6m3/hIt's 6 tons / hour

Q: Can I put in fluid and drive to the Service Station or should I have it towed? The fluid flows out as fast as I put it in. Thanks!: Have it towed, the $60 towing bill is lot less than a new engine, the 1st thing that will happen is one of the heads will crack, next water will mix in with the oil, next engine stops from overheated. Don't have the car pushed, the newer transmissions won't allow this. Ask if who's doing the repairs can tow it free if they fix it, or cut the cost.

Q: My fiance's 2002 Cougar is overheating and we can't seem to diagnose the problem. As soon as she touches the gas pedal, the meter shoots to quot;Hquot;, but when we sit at a red light, it returns to center. I tried googling a few things and I've gotten a few things about the water pump, but I know next to nothing about cars. Where is it so I can look at it and feel dumb about STILL not being able to do anything? =D: Leave the water pump alone! It sounds to me like your gauge is malfunctioning. Every so often an electrical gauge will fail and give strange readings. It could either be the sensor that reads your coolant temp or the gauge body itself. Your car cannot go from overheating to fine while stationary at a red light. Take it to a shop (that specializes in electrical, they're out there) and tell them the temp gauge is acting wacky. If you INSIST to know the location of your water pump...should be on the passenger side of the car mounted to the engine. It's either driven by an accessory belt or the timing belt, I can't remember at the moment. Here's a trick also. Water pumps are designed to leak when they fail. See if you can find coolant spilling out of anywhere a few ounces at a time. Good luck!

Q: How can we calculate the maximum pump pressure for chilled water system for a 20 story building: Once a closed circulating system is filled, the circulating pump needs only to deliver the pressure difference need to take care of circulation losses due to friction and to flow controls. The friction losses will be through the chiller tubes plus through the cooling coils plus thru the longest total circulation piping run. Add to this the pressure drop through the most restrictive regulating valve in the system. This cannot be determined without knowledge of the piping sizes , the components and the respective flows. To take a guess, I would say you would be looking at a circulating pressure rise through the pump of around 30 psi. The static pressure from elevation , about 0.44 pounds per ft of height will be the same in both the supply and return risers and at both the suction and and discharge connections of the pump. So the height of the building need not be considered in the circulaton pressure losses. However the pressure rating of components will need to be suitable for that static pressure. Usually pump casings and pipe fittings are rated for cold water pressures adequate to the approximate static pressure of 90-100 psig on that ground floor or even in the basement of a 200 ft high building. where the pump is assumed to be located.

Q: does water pump sealers work?: If your talking about the water pump for a car it doesn't have any pumps those would be the radiator pumps that are connected to the water pump and transmission which keeps the radiator and transmission at a temperature that keeps the vehicle from over heating. If you have a overheating car and a mechanic told you your water pump has a leak then sorry you would have to replace the water pump but just don't go to a popular mechanic for that because it can get really expensive do your research and find you someone with a garage it cheaper because the part itself is not that expensive it putting it in that cost lol. Hope this helps.

Q: I found a small submersible water pump for pond decorations or birdbaths in my garage. It's about the size of three decks of cards stacked on top of each other. Would there be any harm/benefit of putting this into a 55 gal fw community tank?: No it should be no problem , but run it in the water before you put in the aquarium ..To clean out the pump..

Q: What does water pump mean?: The pump is the pump, and pump the water where you want it

Q: How to introduce water pump?: A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.A pump is a machine that transports liquids or pumps liquids.

Q: The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?: The guage is probably broken, but that is mostly for reference for setting your start/stop switch. Now, first off I'd check your bladder tank. A bad bladder tank will still give you some pressure but causes the pump to run almost constantly. To test that, there is a bicycle looking air valve sticking out of the bladder tank. Push a key or something in it as if you were to let air out of a tire. If any water comes out, your bladder is bad and has to be replaced. If you have an older style deep well, like a well house where the pump is accessible, check the switch, (little black box attached to the pump). There are two screws that can be turned. One sets the pressure the pump will turn off at and the other adjusts the minimum pressure you want for the water to turn back on and fill your tank. A lot of people go 20/40, I run mine at 30/50. Much more than that and you can run into problems, especially if you have cpvc pipes. They will weaken at the elbows and 60 psi of water can eventually make pin hole leaks. This is from personal experience. You will need a working gauge to set this. If the bladder is not your problem, email me and I'll give you more details on how to set your pump if you need it. Or, you can buy preset switches at your local hardware for $20 and just swap it out. In that case, do not mess with the adjustment screws.
