CONTROL APPARATUS OF AIR COMPRESSING EQUIPMENT

摘要

PURPOSE: A control device of an air compressor is provided to improve safety of air compressing operation by assembling essential devices in one main body block. CONSTITUTION: A control device(100) of an air compressor comprises a main body block(110), a check valve(120), a safety valve(130), an opening/closing valve(140), and a control panel(150). The check valve fills an air storage tank with compressed air. When the compressed air is overfilled more than the pre-set pressure, the safety valve leaks a part of the compressed air to the outside of the air storage tank. The opening/closing valve supplies the compressed air stored in the air storage tank to an external device. The control panel has a pressure gauge and a differential pressure controller. The pressure gauge displays the inside pressure of the air storage tank. The differential pressure controller controls operation of the air compressor.
