Abstract

The invention discloses a plunger pump driving device with an automatic compensation function. The plunger pump driving device with the automatic compensation function comprises a hollow cylinder, wherein a plunger is arranged inside the cylinder; a constant pressure overflow valve is arranged inside the plunger; a plunger pin is arranged on the plunger and connected with a crank driving mechanism; the cylinder is connected with a hydraulic cavity of a constant delivery diaphragm pump head; and the cylinder is connected with an oil storage tank through a hose. According to the plunger pump driving device with the automatic compensation function, the problems that an oil supplementary valve of an existing hydraulic diaphragm pump is complicated in structure, and assembling and negative pressure parameter adjustment are difficult are solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic diaphragm pumps, and relates to an automatic compensation plunger pump driving device. Background technique [0002] The hydraulic diaphragm pump relies on the reciprocating movement of the plunger to make the hydraulic fluid in the closed working chamber move forward and retreat, and the diaphragm is driven to perform a protruding-backward deformation movement, and the pressure in the working chamber forms a periodic change of high pressure-negative pressure with the reciprocating movement of the plunger. When the working chamber is under high pressure, it is overflowed by the overflow valve, and when it is under negative pressure, it is replenished by the oil supply valve. The traditional oil supply valve has complex structure, high machining accuracy, and difficult assembly and adjustment of negative pressure parameters. Contents of the invention [0003] The object of the present invention...
