Design methods of slurry pumps in various countries in the world and design advantages of CNZKING slurry pumps

The research on the design method of slurry pump abroad is relatively early. From the data collected, the former Soviet Union, Europe, America, Japan, Australia and other countries and regions have carried out a lot of research work in this regard, but some countries have never officially announced the design of their own companies. method.

1. In 1965, A.J. Stepanov of the United States proposed the theoretical basis of energy conversion when pumping solid-liquid mixtures.

2. In 1991, Nigel P. Brown and Nigel 1. Naywood proposed the working characteristics of the slurry pump. Design principles and requirements

3. Canadian G. Wilson proposed design principles in two articles (design problems of abrasive slurry pumps) and (design characteristics of slurry pumps) in 1981.

4. In 1975, the Australian Warman Company put forward some principle requirements for the slurry pump in the product sample:

(1) The pump flow parts are made of wear-resistant materials

(2) To prevent clogging, the flow channel should be wide

(3) The pump parts must have a considerable thickness

(4) Prevent the working gap from being too small

(5) Bearings should be specially designed

(6) The bearing and shaft are appropriately enlarged

In order to meet the requirements of conveying different media in different industrial and mining conditions, CNZKING has launched products with complete varieties and specifications, a wide range of performances and strong applicability.

From the perspective of the types of impurity pumps, in addition to the types of slurry pumps, there are ash pumps, gravel pumps, dredging pumps, foam pumps, submerged pumps, non-clogging sewage pumps, desulfurization pumps and other pumps, which can be metal pumps. The pump can also be a rubber-lined pump, and the flow parts can also be interchanged with rubber and iron, or a polyurethane pump.

CNZKING's slurry pumps have complete specifications and a wide range of performance. One type of pump, in addition to different speeds and different motor powers, also has different impeller diameters and different number of auxiliary blades to adapt to different departments. The needs of different slurries.
