Description

Technical Field

[0001] This utility model relates to the technical field of power mechanism for dual-liquid grouting pumps, and in particular to a single hydraulic cylinder power mechanism based on the suction and discharge assembly of a dual-liquid grouting pump. Background Technology

[0002] Currently, grouting pumps are used for grouting and water plugging, filling voids, and grouting consolidation of fractured rock layers in gas and coal mines, well construction and underground waterproofing projects, large railway and highway tunnels, reservoir dam foundations, and high-rise building foundations, both domestically and internationally.

[0003] In a dual-liquid grouting pump, liquid A and liquid B are injected through two piston assemblies in the suction and discharge components, respectively. In order to continuously inject liquid, the piston rods of the two piston assemblies need to continuously reciprocate. However, due to the complex working environment of the dual-liquid grouting pump, the piston rods are easily contaminated by dust particles. Simply applying lubricating oil can easily affect the lubrication effect of the piston rods due to dust, ultimately affecting the service life of the piston assembly. Utility Model Content
