Method and apparatus for monitoring the function of a water supply system of a mining machine

摘要

A water supply system of a mining machine is monitored by comparing the number of mechanical recoils in the entry of the cutter bits into the facing mineral with the number of the pressure surges in the water supply system. If conformity is lacking, this is converted into a signal which either leads automatically to shutting off of the machine or leaves the machine driver an only limited time to continue driving the machine. For carrying out the method here an apparatus serves in which a measuring appliance 9 is simultaneously connected for measurement with a pressure gauge 10 allocated to the water supply conduit and a vibration meter 11 allocated for example to the cutter arm, so that the recoils issuing from the individual cutter bits and pressure surges in the water system generated by the valves can be precisely retained and evaluated.
