High-pressure equipment is widely used in the field of agricultural processing, food production, in various industries. The improvement of their design depends on the device reliability, safety of service personnel, productivity and ultimately the cost of production. A feature of the devices design is that their calculation is governed by numerous regulatory documents – state and industry standards, norms etc.
As a result of modeling and calculation, high-pressure devices in the form of a cylinder wrapped in fiberglass are analyzed, equivalent stresses and tensions are defined. Weight ratios are determined. Devices in three-layer design are strong and the least metal-intensive, which significantly reduces weight.
The result of the presented work provides the conclusion that it is more expedient to design a high-pressure apparatus on the basis of a multilayer construction using a fiberglass cylinder winding. The use of the described theoretical calculations will make it possible to fulfill all requirements imposed by the current regulatory documents, reduce the metal consumption of equipment, increase reliability of its operation and reduce the cost, and, finally, improve the quality of the products. The basis of calculations is the correct choice and compilation of calculation schemes, processing of different types of structures and algorithms. The main methods of calculating high-pressure apparatus are the use of the general equation of mass transfer using the Lamé formula and the determination of equivalent stresses in the elements of the high-pressure apparatus.
Further application of theoretical calculations at the design stage will allow developers to find the optimal geometric shapes and sizes of structural units, based on the loads actually acting during the installation operation, which is not always possible using analytical dependencies.
