400DT-A65 Engineering Pump Replacement Parts High Chromium Alloys
Impeller
The 400DT-A65 is a desulfurization pump. The desulfurization pump
is a pump with corrosion resistance and is mainly used for
conveying corrosive liquids. It is a kind of pump that is used very
frequently in the desulfurization equipment industry in the general
equipment pump.
The desulfurization pump is an important equipment in the
desulfurization equipment industry. It is of great help to reduce
the emission of
sulfur dioxide. The desulfurization pump suction cover has been
widely developed and applied.
The impeller of 400DT-A65 adopts high chromium wear-resistant alloy
Cr30, which has excellent corrosion resistance and abrasion
resistance and long service life.
Slurry pump impeller introduction:
The slurry pump impeller refers to a wheel with a moving blade, and
also refers to a general term for a disk and a rotating blade
mounted thereon. The impeller is a key component of the slurry pump
and is a rotating body with blades that transfers energy to the
liquid. It is composed of a number of curved blades.
Classification and function of slurry pump impeller:
1. The slurry pump impeller has the following forms according to
the mechanical structure: closed, semi-closed, open.
(1) Closed impeller
It consists of a blade and a front and rear cover. Closed impellers
are more efficient and more difficult to manufacture, and are most
commonly used in centrifugal pumps. It is suitable for conveying
clean water without particles, such as clean water and solution.
(2) Semi-closed impeller
The semi-closed impeller is suitable for conveying materials that
are easily precipitated or slightly granulated, and its efficiency
is lower than that of a closed impeller.
(3) Open impeller
An impeller with only a blade and no complete cover is called an
open impeller. The open impeller is suitable for conveying
materials containing a large amount of suspended matter, and the
efficiency is low, and the pressure of the liquid to be delivered
is not high.
2, according to its liquid absorption method can be divided into
single suction and double suction.
(1) The single suction type is simple in structure, and the liquid
is only inhaled from one side;
(2) The double suction structure is more complicated, and the
liquid is inhaled from both sides, and has a large liquid
absorption capacity.
3. According to the shape of the blade, it is divided into the
back-bend blade, the radial blade and the front-bend blade. Because
the back-bend blade can obtain higher static pressure energy, the
slurry pump mostly adopts the back-bend blade.
4. The slurry pump impeller is the part of the work done when the
slurry pump is working, and transmits energy through rotation.
5. In the design of the slurry pump, the diameter of the slurry
pump impeller can be cut to achieve the proper flow and lift.
6. The slurry pump impeller is the component of the slurry pump
overcurrent component and is the fastest worn component.

The role of the centrifugal pump impeller: The mechanical energy of
the prime mover is directly transmitted to the liquid to increase
the static pressure and kinetic energy of the liquid to mainly
increase the static pressure energy. The impeller has open,
semi-closed and closed three open impellers without cover on both
sides of the blade. It is easy to manufacture and easy to clean. It
is suitable for conveying materials containing a large amount of
suspended solids. The efficiency is low and the liquid pressure is
not delivered. High; semi-closed impeller has no cover on the
suction side and a cover on the other side, suitable for conveying
materials that are easy to precipitate or contain particles, and
the efficiency is also low; the closed impeller has on both sides
of the impeller Front and rear cover, high efficiency.
