Introduction

Separators are designed to separate components of liquid mixtures (emulsions) according to their density .

Working element of separator is drum rotating at high angular speed. Inside the drum there is a package of thin conical plates that intensify the process of separation of working fluid.

Main part of drum is housing consisting of cylindrical shell and bottom.

The pressure of the liquid in the drum during operation reaches 2 MPa.

In the food and chemical industry, receivers consisting of cylindrical, spherical and other forms of shells are widely used to store liquid gaseous products.

Considering the most important factors affecting the design and strength calculation of the walls, the apparatus of food production can be divided as follows by purpose - for storage and processing, by structural material - steel, cast iron, copper, aluminum; according to the manufacturing method - welded, cast, riveted, soldered, etc.; in shape - cylindrical, spherical, conical, torospheric and combined; according to the load scheme - operating under the influence of internal or external pressure; wall temperature - non-heated, heated or cooled; under conditions of corrosive effect of the medium - operating under conditions of moderate or intense corrosion; by position in space - vertical, horizontal or inclined; according to the method of assembly - detachable or non-detachable; in wall thickness - thin-walled or thick-walled.

These devices are equipped with unified valves, connecting parts and instruments.
