Pump impeller is the main component of the fountain pump, made of cast iron. Pump impeller blade plays a major role, the shape and size of pump impeller and pump performance are closely related. Pump impeller generally can be divided into single suction and double suction two, single suction impeller for the unilateral suction, small flow pump impeller for this type. Double-suction impeller for both sides of the water, large flow pump impeller are used double-suction impeller.
Fountain pumps Pump impeller mainly in the following four forms, (a) closed; (b) before the half-open; (c) the latter half open; (d) open
In this case,
1, closed impeller: from the blade and the front and rear cover composition. Closed impeller high efficiency, manufacturing more difficult, the most used in the fountain pump. Suitable for conveying clean water, solution and other small particles of non-viscosity of the cleaning liquid. In this case,
In this case,
2, semi-open impeller: generally there are two structures one for the former half open, by the rear cover and the blade composition, the structure impeller efficiency is low, in order to improve efficiency with adjustable gap seal ring to another The back half open, from the front cover and the blade composition, as can be applied with the closed pump impeller the same seal ring, efficiency and closed impeller is basically the same, and leaves in addition to conveying liquid, but also has (back blade or vice impeller ) Sealing action. The semi-open impeller is suitable for conveying liquids containing suspended solids such as solid particles and fibers. Semi-open impeller manufacturing less difficult, low cost, and adaptability, in recent years in the refining chemical fountain pump application gradually increased, and for the transportation of water and liquid similar to the water.
In this case,
3, open impeller: only the leaves and leaves stiffeners, no front and rear cover of the impeller (open impeller blades less 2-5). Pump impeller low efficiency, less application, mainly used for conveying high viscosity liquid, and slurry liquid. In this case,
Fountain pumps Impeller blades are generally curved after the leaves. The blade has two kinds of cylindrical and twisted, the use of twisted leaves can reduce the load of the blade, and can improve the fountain pump suction performance and improve the resistance to cavitation, but manufacturing more difficult and costly. In this case,
Pump impeller Refinery chemical fountain pump impeller for casting or all-weld welding of the overall pump impeller. Welding pump impeller is developed in recent years, and more for the poor performance of the casting of metal materials (such as iron and its alloys) chemical manufacturing with special fountain pump. Welding pump impeller geometric accuracy and surface finish are better than casting impeller, help to improve the efficiency of the fountain pump.
