Product Description:

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:well water pumps and systems?
ANY extra info is a plus. Well size and construction, depth, water level, production test results, and pumping apparatus, all help in troubleshooting problems. The two most likely things I can think of that would make your water pressure act the way it does are as follows. My first guess is that your pump is capable of pumping more water than the well will produce, thus drawing the level of water in the well down to a point where the pump catches some air and quits pumping. The pump continues to turn and when enough water comes into the well to cover the pump, it's starts to pump water again. Second guess is that you have a thermal overload tripping and when enough time goes by, it resets and turns the pump on again. Overloads often trip when you have a low voltage situation at the motor. You can get low voltage form bad connections @ splices or the contacts of the pressure switch. Most well water systems go a long time between maintenence calls, especially at first when EVERYTHING is new. My advise would be to call the contractor that drilled the well and installed the pumping equipment. Hopefully they are one and the same. The contractor knows the original conditions and all equipment used, even the stuff you can't see. Because the system is relatively new, the original contractor MAY be inclined to cut you a deal on repairs. We don't know how long this problem has existed, but perhaps the system really wasn't up to par right from the start. Good luck. When you talk to the contractor, try not to sound to accusatory. He may have done his best with the geologic and economic set of conditions he was given. Nobody can make gold out of lead.
Q:Where is the water pump located on a 1999 cadillac deville?
This Site Might Help You. RE: Where is the water pump located on a 1999 cadillac deville? how much would they charge me to change a water pump on my 1999 cadillac deville
Q:water pump or not? need clarification before i spend more money?
some other possible causes of overheat: lean mixture inadequate oiling poor circululation due to restriction in water lines
Q:What water pump do I have to buy to increase the water pressure of the shower?
American Standard has a shower head with a turbine in it. Get that. its made for low flow applications.
Q:Honda Accord 1996, new water pump/timing belt/oil change, smoke coming out from under the car and heats up?
Looks like you should have went ahead and bought the Volkswagen now don't it?
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
Is zero freezing?
Q:How much does a water pump cost?
I checked online and saw Ford Escort water pump for less than $50. But you can always call local auto parts store like Autozone or Pep Boys to get their cost. Allow up to $100 for water pump. Costs for labor are obviously expensive, too. That's what the costs of $300 that some are saying. Consider $100 for pump and $200 for labor. If they actually think that the water pump would cost $300, they forgot that we're talking about an ESCORT!! Not a Lexus or BMW.
Q:How often do I replace the filter in my backpacking water pump?
Could be months yet if you use good water. A filter is good for at least a thousand liters if you're careful with it. So long as the flow is good keep going. Mine is two years old, no problems. I put sterilizer through it every so often. Simple stuff, just buy Camden tablets or powder from a home wine making store or a pharmacist. Make up the solution, pump it through the filter and leave it for an hour then put tap water through it if you want. The Camden tablets are used to stop fermentation in wines and beers and to sterilize the bottles before filling. It isn't rinsed out. Just fill the bottles with the solution, empty them and fill them them with wine or beer. You drink it...it breaks down to harmless sodium sulfate and releases sulfa dioxide which does the sterilizing. Otherwise you can use ordinary household bleach if it's pure bleach with no perfumes or other bits added. A few drops in a pint of water and put it through the unit just as though you are using it normally. Leave it for an hour then run tap water through it. You can use that pure bleach for sterilizing drinking water too but it's best for hot drinks, juice concentrates, and for cooking to mask the chlorine taste. Two drops per liter of water is enough, and leave it for an hour before using. I've used both methods for over forty years of wild camping on five continents, a long malaria field survey in Malaysia, in deserts and forests and on mountains. Never a problem. We used both methods in the Army too for 500 gallon water trucks with barium sulfate filters. Good for 10 000 gallons before changing the barium sulfate. I was the medic doing lab tests on it. Have a good hike.
Q:99 Ram 1500 5.2 Leaking below the water pump?
pump bad or a hose above pump leaking 90% of time pump bad get a flashlight to see more or get a better look have it put on a lift at a shop but most likey water pump gone
Q:what is wrong with my car? is it the water pump or something worse?
Chances are if you had a reputable mechanic tell you it needed a water pump at the time, and he's sure it was leaking.... assuming you haven't overheated the engine that caused gaskets to blow (ie. head gaskets), then a water pump should fix the problem. A good quick check is: is there steam coming out of your tail pipe... if so, you've done more damage than what the water pump will take care of.
