Purpose

Using the special pneumopercussion machines it is improving the efficiency of the process of the thermodynamic processes in the working chambers.

Methodology

The studies were carried on thermodynamic processes of compressed air work in the working chambers of pneumopercussion machines for the increasing their efficiency.

Findings

The article presents efficiency of using compressed air energy in the operation of existing pneumopercussion machines is 15-20%, which significantly increases the cost of drilling operations. Therefore, an increase in efficiency pneumopercussion machines is an important technical challenge. The article discusses ways to increase the efficiency of pneumopercussion machines by combining the most effective thermodynamic processes of compressed air work in the working chambers of pneumopercussion machines and a new technical solution for the design of pneumopercussion machines is proposed. The design of a pneumatic hammer has been developed, which implements the combination of the most effective thermodynamic processes in the chambers of pneumopercussion machines. The design of a new pneumatic hammer is presented, which consumes twice less compressed air during operation than any of the existing hammers with the same frequency and impact energy. Its work and the method of calculating geometric parameters are described.
