Technical Field

The invention belongs to the field of high-pressure homogenizing pumps, and particularly relates to a high-pressure homogenizing pump with a unilateral hydraulic buffer.

Background

The homogenizing pump is a process device capable of uniformly and rapidly plunger-moving liquid materials to the homogenizing interaction cavity for mixing and shearing. The high linear shear velocity generated by the plunger and the strong kinetic energy brought by the high frequency mechanical effect enable the materials to be subjected to the comprehensive actions of strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing, turbulent flow and the like in the narrow gap of the homogeneous cavity to form suspension, emulsion and foam. The invention provides a high-pressure homogenizing pump with a single-side hydraulic buffer, which is used for solving the problems of overlarge hydraulic impact and too fast material suction and easy blockage caused by the fact that a plunger of the existing hydraulic double-side homogenizing pump retracts too fast when reciprocating.
