Slurry Pump Parts - China Slurry pump impeller introduction
The slurry pump impeller refers to the wheel disc equipped with moving blades, and also refers to the general name of the wheel disc and the rotating blades mounted thereon. The impeller is the key component of the slurry pump. It is a rotating body with blades that transfers energy to the liquid. It is composed of several curved blades.
Impeller function:
The role of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to improve the static pressure energy and dynamic pressure energy of the liquid.
Slurry pump impeller material:
Wear-resistant and corrosion-resistant high-chromium alloy (A05, A07, A33, A49), also with rubber impeller
Classification and function of slurry pump impeller:
1. According to the mechanical structure, the slurry pump impeller mainly has the following forms: closed, semi-closed and open.
(1) Closed impeller
It consists of blades and front and rear covers. The closed impeller has high efficiency and is difficult to manufacture, and is most used in centrifugal pumps. It is suitable for conveying clean water, solution and other low-viscosity particle-free cleaning liquids.
(2) Semi-closed impeller
The semi-closed impeller is suitable for conveying materials that are easy to precipitate or contain particles, and its efficiency is lower than that of the closed impeller.
(3) Open impeller
The open impeller is suitable for conveying materials containing more suspended matter, its efficiency is lower, and the pressure of conveying liquid is not high.
2. According to the liquid suction method, it can be divided into single suction type and double suction type.
(1) The single-suction structure is simple, and the liquid is only sucked from one side;
(2) The double-suction structure is more complicated, and the liquid is sucked from both sides, which has a large suction capacity.
3. According to the shape of the blade, it can be divided into backward curved blade, radial blade and forward curved blade. Because the backward curved blade can obtain higher static pressure energy, the slurry pump mostly uses backward curved blade.
4. The impeller of the slurry pump is the work part of the slurry pump, which transfers energy through rotation
5. In the slurry pump selection design, the diameter of the slurry pump impeller can also be cut to achieve the appropriate flow rate and head
6. The slurry pump impeller is the part that does work in the flow part of the slurry pump and is the fastest-wearing part.
