Supplying system abrasive material with automatic dosing control
MetadataShow full item record
The article examines the work and key elements of the automated system for supplying abrasive material using a managed pneumatic dispensing. Proposed to manage the flow of abrasive material using continuous (for the case of emergency braking) and pulse form of dosing. Using the pulse form that allows dosing of abrasive material in a wide range, providing a number of additional options to control the sand system. Developed a functional diagram of the automatic flow of abrasive material supply system, which provides control over the flow of abrasive material and its comparison with the reference case, according to the gradation performance of the system (algorithm of dosing). The main elements of the developed system are analyzed.
