Sleigh Axial-flow Pump introduction
For the sleigh submersible axial-flow pump knowledge,may be a lot
of friends are still very strange,but for its amazing working
ability maybe you have heard. The sleigh submersible axial-flow
pump is very powerful,during working,its flow can reach *0 to **0
cubic meters per hour,its head range can even reach ***0 meters.
What makes the sleigh submersible axial-flow pump so powerful? Now
we are going to analyze it.
Sleigh submersible axial-flow pump is widely used in all areas of
modern industrial production. It can take the underground water to
the surface,and also can make full use of river water for modern
agricultural irrigation, or for people living in the plateau
region,etc. Before the sleigh submersible axial-flow pump
running,the suction tube and the pump are filled with liquid. After
turning on the pump,the impeller begin high-speed rotating,at the
same time the inside liquid also rotates. Under the action of the
centrifugal force,the water in the pump shoot out from the
impeller, finally flow out of the pump outlet and out of from the
discharge pipe through a series of inside setting. Sleigh
submersible axial-flow pump utilizes such a simple physical
principle to realize its own value, which provides the power for
our human production & life and productivity.

Zhonglan Axial Flow Pump performance:
1.Product performance: 1.the motor drives the water pump is the
dry-type fully closed submersible three-phase asynchronous
motor,which can be immersed in water for long time and has a series
incomparable advantages of the traditional pump unit. 2.Since the
motor and the pump constitute a whole part, it is easy and quick to
install on site, no need to carry out the assembly process of
time-consuming & labor-consuming motor transmission and axis
alignment.3. Because of underwater operation, it can greatly
simplify the real geotechnical and building structure engineering
of the pumping station, reduce the installation area, and save
engineering cost by *0 ~ *0%. 4. Low noise,no high temperature in
the pump station,improved operating environment. Building a full
underground pump station according to the requirement keep the
surface environment of ground.
Product use:
it can be used in farmland irrigation and drainage, also in
industrial and mining docks, city construction,water supply,water
supply and drainage of power station,amusement park.
TWO:
Sleigh axial flow pump: the reasons of sleigh submersible axial
flow pump mechanical seal leakage
The sleigh submersible axial-flow pump mechanical seal leakage may
be caused by the abrasion between moving ring surface and static
ring surface of mechanical seal, there are 6 reasons for this
abrasion:
1.Install too tight: check the moving ring surface and static ring
surface of mechanical seal,if there are serious charred and deep
blackened traces,and seal rubber hardening or loss of elasticity
and other phenomena,this is caused by over-tighting. Solution:
adjust the mounting height, pull the spring with a screwdriver
after installation of impeller. The spring will reset after the
release because of its strong tension. Let it have a distance of
**4mm
2.Install too loose:check the moving ring surface and static ring
surface of mechanical seal, the surface has a very thin layer of
scale(can be able to erase), this is caused by the loss of spring
elasticity and poor assembly, or by the axial movement of the
motor.
3.Poor water quality with particles: The poor water
quality,containing small particles and high content of
hydrochloride in the medium cause abrasive materials and wear the
mechanical seal plane or strain the surface, and then form groove
& ring groove and other phenomenon. Solution: improve water
pressure or medium,change the mechanical seal.
4.Running without water causes dry grinding damage:this phenomenon
is more commen in the bottom valve installed in the form of
negative pressure at the inlet, air in the pipe inlet, and there is
air in the pump chamber, after turning on the pump, the friction of
the mechanical seal running at high speed produces high
temperature, unable to get cooling, check the mechanical seal, the
spring tension is okay, the friction surface is charred and
blackened, the rubber becomes hard and cracked. Spolution: empty
the air inside the pipe and pump chamber, change the mechanical
seal.
5.Cavitation : cavitation corrosion mainly occurs in hot water
pumps. Due to the medium is hot water, steam is produced when the
water temperature is too high. The steam in the pipeline enters
into the pump chamber and can not be excluded,resulting in
water shortage and failure of the seal dry grinding. Solution:
installing automatic exhaust valve,change the mechanical seal.
6.Assembly problem: the pump cover may not be mounted flat during
the installation,making the shaft and the pump cover are in the
non-vertical,which caused the static plane and the moving plane can
not meet properly, in a short time after turning on the
pump,causeing the pumps unilateral wear and seepage.
Solution:remove it and reinstall it,check if the pump cover is
installed flat.
THREE:
The voltage and flow of Zhonglan Sleigh submersible axial-flow pump
are rated. Under this condition, if the pump is continuously
operated for **2 hours,,the pump running will reach a stable state.
The performance test of sleigh submersible axial flow pump starts
from the minimum point of power. For mixed flow pumps,axial flow
pumps,or whirlpool pumps,the valve should be fully running from the
start. That is the difference in the beginning. During the
measurement period ,*3 measurement points should be taken, and the
measurement points should be evenly distributed across the whole
performance curve. Each point should be measured at a time interval
to ensure that the point reaches a stable state.
According to the professional introduction, from the perspective of
measurement of sleigh submersible axial flow pump,three-phase
submersible pump should read three-phase current, power,power
frequency,speed tolerance,water head range and flow value.
Single-phase submersible pump for split phase starting and
capacitor start motor should read power, stator main winding
current, power frequency,speed tolerance,water head range and flow
value, for capacitor running and capacitor start running motor
should read power,stator main winding current and stator
assistant winding current,power frequency,speed tolerance,water
head range and flow value.
FOUR:
With the development of electric power technology, there are more
and more types of submersible pumps,it is inevitable that
submersible pumps vibrate during running. The reason for vibration
of sleigh submersible axial-flow pump are as follows: 1.Sleigh
submersible axial-flow pump rotor is unbalanced in the
manufacturing process,pump and pump shaft is at different
center,collision and friction occur between rotor and stator. 2.
Being used for a long time cause wear and aging,impeller loosing,
bearing damage or bearing clearance. 3. There are sundries in the
pipe inlet and impeller and the foundation of the submersible
axial-flow pump is fixed not stable,which cause resonance
strengthening. 4.While sleigh submersible axial-flow pump working
to promote the flow,accompaning eddy current and cavitation arise
vibration inevitably. It can be seen that sleigh submersible
axial-flow pump vibrates is not necessarily a problem,can be
checked by above methods.
