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:i have just bought a coachman 1994 wanderer but water pump do`snt work,there are 3 wires to pump socket inside the van,white,red,yellow,only the white was fitted and reads 12v to earth,the other 2 read 6v to earth, any help as I cant find a wiring diagram on net !: never seen a water pump that had any wires just ones with two rubber hoses and a few bolts to hold it on

Q:should replace timing belt & water pump on a newly purchased used vehicle..if no records of last x changed?: It is wise to seek advise from professional mechanics as to what process you are considering to do with this vehicle. This vehicle is 2013-1994= 19/20 years old presumably in service since 1994. The miles you report as under 160,000 miles. You inquire as if you are inexperienced in automotive affairs. Well, here is my experience speaking. Any vehicle over 100,000 miles is to be suspect of wear and tear and even abuse by prior owners and they require inspection and evaluation. Engines are to be checked for compression and leaks, electrical system, corrosion, engine mounts, exhaust, transmission, coolant system, etc. etc. etc. Only a trained mechanic can do this. Unless you have receipts, records at a dealership, etc. as evidence of service and repairs, then all parts are original. You ask as to the timing chain. I expand to include everything proposing short of an engine rebuild. Cars do a lot of work and suffer deterioration each second the motor runs and each inch the car moves over the earth. IF there an inspection plate or port that provides for a viewing of the condition of the timing belt, a mechanic will know. My car, a 2001 Audi TT has that feature. Now, imagine the purchase price of this Toyota, add the expense of the inspection and possible repairs such as the timing belt, water pump, thermostat, radiator cap and coolant replacement, possible a new radiator, suspension parts, exhaust parts, etc. in need of replacement, etc. and it is up to you to decide IF this vehicle is worth the expense for no matter how money you spend, the retail market value shall remain the same. That means around $2,500 to $2,700. This vehicle, as new, was not and is not now, a fuel efficient vehicle with an average MPG of 14 MPG on a good day. I do not know as to your driving needs but at 60 MPH and 14 MPG that mean each 14 miles $3.50, average, goes out the tail pipe for a nice $14.00 per HOUR cost on fuel. Kind of expensive. You choice and decision. Good luck.

Q:I took my 04 Grand Prix to the mechanic for a coolant change. My car had never drip coolant until after the coolant change . I took my car today to the same mechanic and he told me that the problem was the water pump and wants to charge me 70 dollars. Could changing the coolant affect the water pump. Or did the mechanic damaged the water pump on purpose.: Changing the coolant would not damage your water pump, especially not in a short period of time. Water pumps just eventually go bad and the first sign is usually a leak. If your mechanic is going to replace your water pump for 70 dollars I think that sounds very reasonable.

Q:A total of three units, usually starting two units. After jumping the gate, it was like this. I haven't paid attention before. Is it a turn around?: The water pump with frequency conversion is set correctly and will not burn the motor. If there is a problem, the frequency converter will automatically stop running. The frequency converter can change the positive and negative (frequency changer without this function, change the phase sequence)

Q:What is the safety head of a pump? Why should a safety head be added?: The pump achieves this by providing sufficient energy to the liquid at the entrance of the impeller, and ensuring that the liquid remains liquid. This energy is known as the available cavitation margin, referred to as NPSH (A).If there is not enough NPSH (A) or energy, as soon as the liquid enters the impeller, its velocity is increased. According to Pohl's law, the pressure drops. A reduction in pressure will cause some molecules in the liquid to become gaseous, forming vapor bubbles.The performance of the pump will be lowered immediately and the bubbles will continue to grow until the pressure inside the pump causes them to implode.In brief, it is to avoid cavitation.

Q:im buying a mazda 626 for 800 abd the owner selling just let me know that the water pump is going out. is it a fairly easy fix or should i keep shopping for a vehicle?: keep shopping, water pump will run about $30 and if you take it to a shop they'll charge $150 if not more to install, it'd be best to find a car in better condition

Q:I have a 1999 Chrysler LHS. Recently, the water pump started leaking and it ruined the timing belt. I brought it to a mechanic that I've never used before, so I have no idea how reliable they are. They now told me that my brake lines blew. Can the leaking water pump also cause brake lines to rot?: No but if the brake lines are as rusted up as they usually get any movement could cause a leak. At this point the mechanic did you a favor by bumping them and causing the leak. Sure beats finding out the lines are weak while coming off the expressway.

Q:I am a business man.My Instituate name is Rockydockyard.This Institiate build up Ships,containerships etc.So we found a high pressure water pump.: OK wheres the question?

Q:me and my friends are contemplating going on a road trip.almost 20 hours of driving.but we dont have a water pump, can you drive without one?: Not unless you intend to spent about 4 days walking the 19 1/2 hours that will be left of your trip after the engine seizes up.

Q:the pump inlet how hard is this to replace i know the timing chain cover has to be removed and is this the propable place of the leak: You can't fix it. Wanna' know why? You are here.
