Hydraulic Single Pump with Combined Higher Volume Compensator Operation Analysis

The article dwells on the operation peculiarities of a mortar pump with a hydraulic drive, ball suction and spring-loaded discharge valves, a special insert in the suction chamber and an increased volume compensator. A comparative analysis of the mortar pump operating modes with various drives is presented. Based on theoretical studies of determining the productivity and volumetric efficiency, it is proved that a hydraulic drive mortar pump with a combined compensator of increased volume works more efficiently in relation to a mortar pump with a combined compensator of increased volume. The rational operating modes areas of the hydraulic drive mortar pump are determined.
