Axial Flow Propeller Pump

Propeller Pump Product description

QZ series axial flow pumps are modern products successfully designed through adopting foreign modern technology. The new pumps’ capacity are 20% larger than the old ones. The efficiency is 3%-5% higher than the old ones. QZ series pump with adjustable impellers has the advantages of large capacity, broad head, high efficiency, wide application and so on. Pump station is small in scale, the construction is simple and the investment is greatly decreased. This can save 30%-40% for the building cost. It is easy to install,maintain and repair this kind of pump. Low noise,long life.

Propeller Pump Application

QZ series axial-flow pump is applicable for water supply in cities, diversion works, sewage drainage system, sewage disposal project.

Q:If there were no water at the discharge of a pump and then you had just fed water through and measured the pressure of the gauge...would that be a different pressure if the whole system (both inlet and outlet) were continuously filled with water?: 1.If there is no water at the discharge of the pump then there can be no pressure. 2. If there is water at the discharge of the pump, but the pump is not running, then there will be a pressure in the system. 3. If the pump is running, the pressure in the system will be higher than at 2.) above becuse it takes additional pressure to move the water through the piping. The flowing water requires additional pressure to get thru the piping system.

Q:My 2000 Chevy Cavalier (2.4L) has been overheating pretty majorly (within a 10 minute drive!) when it's been super cold out, about 5F. I took it to the shop and they told me it was my water pump. Right after getting out of the shop, the problem went away for an entire week and the car's temperature has been at exactly what it's been for years - never past 195. It seems to be back now, though not as severe. It's about 20F now.Could the weather have to do with this??Why would the problem go away like that?I'm female and definitely do not seem educated walking into a shop so they can really tell me anything and I'll buy it. I just wanna see if the problem going away like that makes any sense, or if I should just wait out long trips until it warms up outside.It doesn't look like I'm losing coolant, though my low coolant light goes in and out.I have no idea. Thoughts?Thank you!!: There's lots of possible damage that can occur in an overheat condition. Best to get it in somewhere with a laser temp gauge to track the problem in the system. There is a good possibility the thermostat is going bad if you are overheating and not losing coolant. That indicates a blockage to stop coolant flow.

Q:I recently took my 2002 Pontiac Grand Prix in for an oil change, and was told that my water pump has burst. I knew something happened the previous night because all of a sudden my car was overheating and when I opened the hood there was water everywhere, Anyways I am currently a single mom, working temp jobs while I look for something permanent. I can not afford the 350.00 to get it fixed. If I continue to drive the car am I looking at serious damage, He showed me how to fill the water tank (or whatever) so that the car will not be empty, But he says I need to get it fixed soon: This Site Might Help You.

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:i need to change my water pump on my vw 1990 gti. the more details and/or pictures the better or links i can go to to show me: Buy a repair manual. Or better yet buy a lifetime replacment one at Autozone and they will print out a step by step (with pictures torque specs) instructions for you. :)

Q:Pump flow 6M3/H is an hour, how many tons of water?: Flow 6M3/H, that is, an hour can smoke 6 tons of water. But according to the power, head and flow calculated by formula, the water pump efficiency is 98%, can it be achieved?

Q:It stops and every few minutes and when it stops, it sounds like water is running.: Your pump switch's on when the demand for water is required. The pump, pumps water at a certain rate of P.S.I (Pounds per Square inch) and depending on brand of pump will maintain a standard of pressure through out the house. If for any reason the pressure drops, the pump will automatically kick in to maintain pressure and volume of water required by it. A leaking faucet, or a toilet that is constantly running will drop pressure slowly. Check all your plumbing fixtures, including hot water heaters/storage heaters, boilers, furnaces, and any item/fixture the requires water to see if it is leaking, or passing water into a drain constantly. If problem persists contact a plumber. If the pump starts to labor to much, or starts to run constantly if may burn out rendering the pump useless.

Q:Okay, I have a 1982 Suzuki Dt8 that someone gave me. But it will not pump water well, when you reve it it will have a little watter shoot out the water outlit, but heres the thing. if you take the cover off be the shift linkage and run the engin it will pump water through just fine: I've passed on answering your question a couple times, mainly because I'm not sure exactly what you are asking. So let me ask. In the water does the engine overheat? I'm not sure that what you are looking at isn't the relief hole and not the water discharge, which should be under water. How are you supplying water to your engine? Are you running in a barrel? The water pump should be replaced every 2-3 years, so unless you are going to do it yourself, take it to a shop and explain what you are observing. Taking the cowling off will have no effect on the water pump, so I'm guessing you are looking at the wrong place. P.S. This was a common error with Evinrude small motors back in the 70's and 80's, motors similar to yours. The exhaust fin was just behind the propeller. not higher up the leg

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: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?????: your water pump is bad if it leaks or whines. Sounds like yours leaked when you rcar overheated. I'd suggest that the overheating problem may have been caused by something else though, as you said that the water levels were not going down until it overheated. I would suggest you may have had a head gasket problem or thermostat or radiator problem. Now it sounds like you have done a lot of damage by allowing it to get so hot. You may have a ruined engine I'm afraid. It might have seized. Tip;- don't carry on driving when it keeps overheating. It does a lot more expensive damage if you do. Take your car to a professional to get it checked out. Expect the worse. Sorry to sound so gloomy, but I'm just trying to prepare you. I hope for your sake it isn't as bad as I think. Good Luck
