Abstract

The invention discloses an automatic oil charging and discharging device of a diaphragm pump, comprising a piston cylinder and a piston arranged in the piston cylinder, wherein a pipe cavity of a hydraulic pipe forms an oil cavity; a diaphragm is arranged between a delivery pipeline and the oil cavity; the middle part of the diaphragm is connected with one end of a guide rod; the other end of the guide rod is a guide rod contact; an oil charging valve and an oil discharging valve are arranged on the side wall of the hydraulic pipe and are respectively connected with an oil station; the oil charging valve and the oil discharging valve respectively comprise a valve body; each valve body is internally provided with a containing cavity; the containing cavity is internally provided with a return spring and a sliding valve rod matched with the containing cavity in a sliding manner; one end of the return spring is fixed at the bottom part of the containing cavity, and the other end of the return spring is connected with one end of the sliding valve rod; the other end of the sliding valve rod is sliding valve rod contacts which penetrate out of the containing cavity and enters the oil cavity; the guide rod contact is positioned between the sliding valve rod contact of the oil charging valve and the sliding valve rod contact of the oil discharging valve; and the front and rear stroke of the guide rod is controlled, so that the automatic oil charging in oil starvation and automatic oil discharging in more oil are achieved.
