Early warning method of impending water supply interruption in water supply system

摘要

The present invention relates to a method of controlling a water supply system (1) used with a machine tool (2), particularly a core drill apparatus, the water supply system (1) , A water supply passage (5) having a first portion (17) and a second portion (18) for conveying water from the water reservoir (4) to the machine tool (2) At least one sensor (8) for measuring at least one parameter of the pumping device (7); a pumping device (7) for delivering water to the machine tool (2) And a control device (9). The method according to the invention is characterized in that the at least one parameter of the pumping device (7) drops below a predetermined threshold value over a predetermined period and supplies a predetermined quantity of water to the machine tool (2) When it is available for use.BACKGROUND OF THE INVENTION
