sewage pump impeller, water pump impeller pictures, characteristics of sewage pump impeller

with the continuous development of industrial and agricultural production, in the chemical industry, mining, food, construction, paper and other industries of technological process, domestic sewage and industrial wastewater emissions, require a lot of conveying liquid containing solid particles suspended solids or fibrous suspension non-clog pump, the current commonly used non-clog pump WQ submersible sewage pump, vertical sewage pump and horizontal sewage pump, etc. Whatever the structure form of non-clog sewage pump, if you want to achieve without blocking performance, the key lies in the structure of sewage pump impeller.

picture and characteristics of the sewage pump impeller sewage pump impeller

( 1) Closed sewage pump impeller features: closed design, manufacturing and general centrifugal pump impeller. Its advantage is relatively high efficiency, to ensure stable operation condition in a long time. The downside is easy, anti-clogging performance is poor. If used in non-clog pump, general use 2 - The three blades, and USES the larger exit width.

( 2) Open or half open sewage water pump impeller features: open or half open impeller has the advantage of easy fabrication, easy to clean up when the impeller blocking. Its disadvantage is that before after wear will cause the impeller and the pump cover inside wall cross gap increases, resulting in a decline in the efficiency, and caused a lot of vortex loss. At the same time, also will increase the axial force of pump, the flow of fluid flow between stability, easy cause larger radial force and vibration.

use of half open impeller pump are: desulfurization circulating pump open impeller products are: mud pump

( 3) Swirl characteristics of sewage pump impeller: swirling sewage pump impeller structure is simple, easy to manufacture, and stable performance, reliable operation, good yuan blocking performance, especially suitable for conveying raw, containing solid and easy winding or bunching of the fiber material properties of the liquid. Its main disadvantage is low efficiency, poor condition sexual.

( 4) Characteristics of screw centrifugal water pump impeller: spiral centrifugal impeller without blocking performance is good, passing ability, and the flow is smooth, good condition, high efficiency and power curve is flat, suck person performance is good, can deliver a high concentration of slurry. Its main drawback is that the impeller manufacture is difficult, and in the small flow running just can produce bigger vibration and noise.

( 5) Features: port sewage pump impeller flow channel impeller is also called the impeller blades, can be divided into single flow channel impeller, ochre and three flow impeller flow channel impeller, as shown in figure 11 a 1. Imports from the impeller to the out of date, respectively is 1 ~ 3 distorted flow space, suitable for transporting large particles or liquid containing long fiber material.

port impeller winding, no jam resistance is the best in several non-clog impeller, pump's efficiency is higher, power curve is flat, there is a better wear resistance. Shuangliu impeller due to balance good, smooth operation, reliable and widely used.
