Increasing operational reliability of pneumatic brake system of trucks and buses by compressed air dehumidification method developing
EDN: AULKGH
Abstract
Introduction (problem statement and relevance). As a working medium, compressed air has become widespread in pneumatic system gears of ground vehicles, including brake systems of trucks and buses, due to its high operational properties. Climatic stability of pneumatic systems ensures stability of operational characteristics in case of temperature fluctuations. Compressed air is particularly used in brake systems of trucks and buses due to its safety, availability and economic efficiency. However, there are problems related to high concentration of in-air moisture that may get inside the pneumatic system and lead to condensation and corrosion of the pneumatic system parts, and in winter time – to its freezing. This, in turn, may lead to failures of equipment of brake system components, as well as emergencies with ground vehicles.
The purpose of the study is to analyze the main modern methods of compressed air dehumidification applied in pneumatic systems of ground vehicles, evaluate their efficiency level and propose the most rational dehumidification method for compressed air within pneumatic brake systems of ground vehicles.
Methodology and research methods. The study used the method of system analysis of Russian and foreign research on dehumidification of compressed air within pneumatic systems of ground vehicles.
Study results. The paper proposes an innovative approach to the compressed air dehumidification process within pneumatic systems of ground vehicles by integrating and optimizing various modern methods of compressed air dehumidification for ground vehicles.
Practical significance. The main failures of pneumatic systems of ground vehicles caused by moisture in them have been summarized, a number of key aspects contributing to the operation improvement of pneumatic systems of ground vehicles have been provided.
