High Concentration And Strong Abrasive Slurry Pump For Mining And
Metallurgical
Product overview
1. The frame plates for pumps have replaceable wear-resistant metal
liners or rubber liners. The
impellers are made of wear-resistant metal or rubber. The frame
plate liner and impeller for HH pump
are adoptable of hard metal only.
2. Bearing assembly use cylindrical structure,adjusting the space
between impeller and front liner easily,
being removed completely when being repaired. Bearing assembly use
grease lubrication.
3. The shaft seal could use the packing seal, expeller seal and
mechanical seal.
4. The discharge branch can be positioned at intervals of 45
degrees by request and oriented to any
eight positions to suit installations and applications.
5. There are the drive types, such as V belt drive, gear reducer
drive, fluid coupling drive, frequency conversion drive devices.
6. Wide performance, good NPSH and high efficiency. The pump of
this type may be installed in
multistage series to meet the delivery for long distance.
Working Principle
1. Before the pump works, the slurry pump bearing, the staff must
first inject the liquid used for conveying into the pipeline and
the pump casing, and fill the two;
2. When the slurry pump is started, the liquid in the impeller will
be rotated by the blades of the impeller;
3. Under the action of centrifugal force, the liquid rotates
forward and then flows out of the impeller;
4. In the process of liquid flowing from the impeller inlet to the
impeller outlet, the slurry pump forum, the speed energy and the
pressure energy are increased due to the energy conversion, and the
liquid flowing out from the impeller is discharged through the pump
casing flow passage and then discharged from the discharge pipe;
5. At this time, the impeller inlet is formed by the discharge of
water, and the slurry pump, the liquid in the suction surface is
pressed into the water inlet of the impeller under the action of
atmospheric pressure;
6. The rotating impeller continuously draws in and vents water to
form a continuous stream of water.
Intruction
1.This series of slurry pumps is an energy efficient, single stage,
single suction, cantilever centrifugal pump for conveying abrasive
or corrosive slurries containing solid particles. Widely used in
power, mining, metallurgy, coal, building materials, chemicals,
food, water conservancy and sewage treatment industries. The large
weight concentration of the solid-liquid mixture is 45% for the
mortar and 60% for the slurry.
2, this series of pumps has more than 50 basic models, slurry pump
design, through the variable speed can get more than 300 kinds of
performance for users to choose.
3, the material of the flow component should be based on the
physical (particle composition, particle size, shape, hardness,
concentration) and chemical (acid, alkali, oil) characteristics of
the transport slurry.
4. The transmission mode of the pump has two forms: direct
transmission and belt transmission, which are divided into DC, HC,
CR, CL, ZV, CV and other modes. (See Appendix 3 for details.) From
the direction of the prime mover, the pump rotates clockwise.
