Type description
Take 350QZB-50 as an example
350: the nominal diameter of the pump
Q: submersible
Z: axial flow
B: semi-adjustable blade
50: 1/10 of the pump specific speed (take the integer part)
According to different pump specific speeds, the flow capacity range of this type of axial flow pump can reach up to 700m3-1400 m3
The principle of Axial flow pump is to lifting water according to the thrust caused by the impeller when rotating. Because water moves along the axial in the impeller, so we called it axial flow pump.
In accordance with its mode of installation, axial flow pump can be distinguished into three class: vertical, horizontal, inclined. Their structures are almost the same. Now the vertical form is used widely. The main accessories contains bell-mouthed pipe, impeller, guide blade, outlet syphon, shaft and bearing, stuffing box, etc.
Summarize of QZ series Axial flow pump:
Installation of water flow Channel: in terms of recommended sample installation diagram
The form of water exit: flap valve or other ways
Installation ways: suspended by bent pipe; suspended in well casing, etc.
Motor
Submersible motor
Power Level: electrical performance conforms to GB756
Protection level: IP68
Cooling method: ICW08A41
Basic installation form: IM3013
Voltage grade: ≤355kw, voltage,380v/660v; 355kw,voltage, 380v, 660v, 6000v, 10000v
Insulation level: F
Rated frequency: 50Hz
Length of cable: 10m
Shaft seal
There are two or three stages of mechanical seal. The first stage called carborundum (directly contact with water). The second and third stage called graphite and carborundum.
Leak proof Equipment
QZ, QH series pump have been equipped with leak proof sensors. When the oil tank, the inner part of motor or the junction box has been leaked by water, the sensor will signal or made the motor shut down, and retain the malfunction signal.
Over heating protection system
A overheating protection device is fastened on the motor winding. When the temperature exceeds the stated ＆#118alue, the device will signal or made the motor shut down.
Rotation direction:
Seen from the top of the motor, the impeller is rotating clock wisely.
Application
QZ series axial flow pump, QH series mixed-flow pump is widely used in industry and agriculture water lifting, urban water supply, light polluted water discharge and other water transfer project.
Working condition
Clean water with the temperature no more than 50 or some liquids that are similar to water.
- Q: the pump is pumping hot wtaer from the hot water tank around the domestic hot water system, i.e to taps and shower.
- These pumps can have their own bearing or they may rely on the bearings in the motor. Most of these are anti-friction bearings that have a limited life. Also if the pump runs dry it can over heat and seize.
- Q: I've always wondered how a water pump moves water through a pipe. A fan moves air by spinning a propeller-like set of blades, but does a water pump work the same way? Or is there some other kind of mechanism inside the pump that draws water from one place and pushes it to another?
- IT CAN BE LIKE A FAN (CENTRIFUGE) OR IT CAN USE SUCTION AND GRAVITY LIKE A WELL PUMP
- Q: Just touch this area, a lot of places do not understandFor example, I have a water pump, for 11kw, choose circuit breaker, then what model should be chosen more appropriate, it is best to recommend a Schneider, universal DW recommend oneCan explain in detail, better, I checked online selection manual, there are many places that feel fuzzyIn addition, 37KW, 22KW, 1.5KW each choose what type?Hope predecessors give advice
- Schneider circuit breaker is not selected, I do not know how much current to drive the 11kw pump, and there is no other load?
- Q: What does the pump lift mean?
- The pump head is the parameter you must know when you buy a pump, that is, the height of the pump.To buy a pump, I think the Heathrow pump is OK. I bought it earlier this year. It's not bad yet, but the quality is pretty good.
- Q: can a water pump pumping out air instead of water?
- It wouldnt last long as the water acts as a lubricant and the seals would fail as a result .The bearings would also overheat if relying on being cooled by the water
- Q: I moved into a house on a rural property in January, and we live off tank water and have a Grunfos PT18 pumping all our water into the house.The problem is, not all the time, but alot of the time my pump stays on after having a shower, the motor keeps running and restarting continuously as if it is desperately trying to pump more water through, until I go underneath my house and literally turn it off at the powerpoint, wait for a bit then turn it back on. I am scared if I leave the motor keep going like that it will burn my pump out. Does anyone have any suggestions on how I can fix this problem, or why it may be doing this, or is something causing it?Thankyou in advance, from someone who has next to no knowledge about pumps!!
- Just adding a little more info to Corkeys list. Your foot valve could be stuck open and the water is draining back to the well. You will have to pull up the well line and replace the foot valve.
- Q: i heard a water pump should not be able to move.is that correct? It is a 1995 RM250. there is no clogging in the pipes coming from the radiators with 2 fingers require force to move them but with the 1 finger it requires no force to move a couple Centimeters.
- The water pump is turned by the primary gear on the crankshaft. When you were turning the water pump - the crankshaft was moving the piston up down in the cylinder. The couple of centimeters of movement is just the play between the gears - that's normal.
- Q: Hey for the past month my car has been leaking coolant, making a wierd noise when i drive it, and saying low coolant when its filled to the top.my husband took it out to get gas this morning and it stopped on him and had to be towed to the mechanicthe mechanic said its the water pump and somethin about anti freeze and this cost almost 300 bucks with parts and laborim just wanting to know if a water pump does indeed cause issues like this before we dish out this kinda money!!! btw its a 96 chevy luminathanks
- The water pump pumps cooled water around the engine, so yes if it has an issue like leaking then there is a very high chance that the engine will overheat. Anti-freeze is only really required in the winter when temperatures get low enough to freeze the water in the system and therefore will not be able to be pumped around the engine, as it's now summer there is no danger not using anti-freeze but is advisable to get some added before the cold weather comes.
- Q: Installed new water pump on 90 Jeep. Noticed antifreeze around the edges of the pump. Took it off, replaced with new gasket and sealer, but it seams to be leaking again.
- Could be a defective pump. I've had that happen to me already. Might be that one of the surfaces still has some of the old gasket remaining or perhaps some uneven spots. In that case I would recommend high-tack gasket sealer by permatex. Check to see that the antifreeze is not coming from elsewhere like from a by-pass hose or from the intake. It could be possible that the pump was not the only thing at fault. Hope that helps.
- Q: we changed the water pump it went bad and there is still a knock in it please help it is running really sluggish
- I'm assuming you replaced the water pump due to an overheating problem (most water pumps fail due to leakage, so I'm assuming you drove the car with low coolant). If this is the case and you have an engine knock, you're in trouble. A knock signifies damage to the crankshaft/piston/connecting rod and the associated bearings. If it sounds like someone is hitting the engine with a hammer, you'll need to bring it in right away, before you do more damage. It's not going to be cheap (when is it with a BMW) and you may be better off selling the car and starting with a new car. Good luck. Greg
