CHIEF USAGE

QZ QH QZ series axial-flow pump QH series mixed-flow pumps

application rang e:water supply in cities, diversion works, sew

-age drainage system, sewage disposal project.

WORKING CONDITIONS

o

50 C

o

The medium for pure-water should be no larger than 50 C.

QZ series axial-flow pumps QH series mixed-flow pumps

are modern productions successfully designed by the means of

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 QH series pump with adjust able impellers has the

advantages of large capacity,broad head, high efficiency, wide

application and so on.

A: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.

B: It is easy to install maintain and repair this kind of

pump.

C: low noise long life.

The material of the series of QZ QH can be castiron

ductile iron copper or stainless steel.

Installation of Suction and Discharge Pipes

1.Suction Pipe:according to the outline drawing in the booklet. The

smallest depth of the pump under the water should be bigger

than the datum in the drawing.

2.Discharge:flap valve and other methods.

3.Installation:QZ series are suitable for elbow cantilever in-

stallation,well cantiever installation and concrete well canti-

lever installation. Our company will supply whole set of steel

well pipe for elbow cantilever and well cantilever install-

ation. For concrete well cantilever installation, our comp-

any wi ll pr ovid e cover and brackets. LZ and JZ series have

open or shut installation. The length of cardon shaft can be

made according to different requirements of customers.

Motor

1. Submersible Motor(QZ series)

Power class:electric performance meets GB755

Protection class:IP68

Cooling system:ICWO8A41

Basic installation type: IM3013

Voltage: up to 355kw, 380V 600V 355KW, 380V 600V

6kv, 10kv

Insulation class: F

Rated power: 50Hz

Length of cable: 10m

Shaft Seal

This type has two or three mechanical seals. The first sea l,

which contacts water, is usually made of carbon silicon and carbon

silicon. The second and third are usually made of graphite and

carbon silicon.

Leakage Protection

QZ QH series has leakage protection sensor. When the oil

house of motor or the wire-box is leeking, sensor will give out

warning or stop working and maintain the signal.

Overheat Protector

The winding of QZ series submersible motor has overheat

protector. When it is overheated, warning will be given out or

the motor will stop working.

Rotating Direction

Looking from upper side, the impeller is rotating clockwise.
