Introduction

Relevance. In life and in his development, man always felt the need to move (transport) various substances, hydraulic mixtures, as well as loose, viscous and other materials.

The device for the pressure movement of materials (suction and discharge), mainly liquids, with the communication of external energy to them was called a pump. invention relates to ancient times. The history of the development of the naso-structure, like all the development of technology, is connected with the needs of human society at each stage of its development, and many of the minds of mankind are involved in it.

In accordance with GOST 1738972, the classification of all pumps is divided into types and varieties according to various features, for example, according to the principle of design action.

Conventionally, pumps can be divided into two groups:

1) pumps driven by motors;

2) pumps operating by other energy sources and having no moving working elements.

Pumps-machines are:

- vane (centrifugal, axial, vortex);

- volume (piston, rotor, gear, screw, re-installation, etc.).

Pumps - devices are:

- inkjet;

- gas elevators (including airlifts);

In addition, devices and other applications are known:

- vacuum pumps;

- heat pumps.

Vane pumps are the main type of pumps (at least 75% of industrial pumps) in terms of productivity, versatility and prevalence.

The purpose of the project is "Calculation and selection of a type K centrifugal pump."

Tasks:

- calculate the impeller of the centrifugal pump;

- calculate the spiral discharge of the centrifugal pump.
