The analysis of running efficiency of valve units in differential mortar pump

The Fracture Process of the Mortar Pump’s Work Surfaces with Abrasive Particles

“…One of the most important problems for carrying out the stated above construction works is the provision of sufficient equipment operational life through the choice of rational forms and operating modes of mortar pumps' rubbing parts and constructional materials from which they are made. On the basis of literary sources review [1,2] it is possible to outline two ways to increase the mortar pumps reliabilitytechnological and constructive ones. The technological way of increasing the reliability of mortar pumps is to improve the manufacturing quality of the parts of the cylinder-piston group, valve units and gland boxes, drive parts, as well as to use wear-resistant materials for the manufacture of these parts, in use of modern methods of heat treatment and thermochemical treatment.…”
