Abstract:
An automatic pneumatic pump system, comprising:a fluid reservoir;at least fluid tank connected to said reservoir through an inlet conduit and discharging fluid through an outlet conduit;a pressure sensing unit mounted on each fluid tank and containing a high pressure sensor and a low pressure sensor;a fluid level sensing unit mounted on each fluid tank and containing a high fluid level sensor and a low fluid level sensor;a microprocessor controlling an operation of the system;an air supply conduit connecting the fluid tank to a compressor, said air supply conduit connected to said fluid level sensing unit, with the interior of said fluid level sensing unit being configured to communicate with said fluid tank; and an auxiliary air tank connected to both said air supply conduit and said air discharge conduit; andan air discharge conduit extending from the fluid tank, whereby the automatic pneumatic pump system effectively and automatically cleans the fluid level sensing unit improves pupming capacity, and recyclines dischanged and compressed air.
