BENCH FOR TESTING FLUID TRANSPORTING DEVICE

摘要

FIELD: testing engineering. ^ SUBSTANCE: bench comprises measuring section of pipeline of round cross-section, pump with sucking and pressure branch pipes, and measuring instruments for measuring pressure. Two pistons are mounted at free ends of the measuring section for permitting longitudinal motion. The first end of the measuring section is provided with detachable plug, and the second end is connected with the pressure branch pipe of the water pump whose sucking branch pipe is set in the water tank for permitting supplying water to the inner space of the measuring section. The central part of the measuring section of pipeline is provided with a hopper for permitting paste-like water mixture to be supplied through it to the inner space of the measuring section. The plugged end of the measuring section is connected with the valve through the second additional pipeline for permitting supplying water to the space of the measuring section defined by the plug and the second piston. The spaces between the free ends and pistons are in communication with pressure gages. The hoppers are made of passages oriented perpendicular to the measuring section of pipeline and having rectangular cross-section. The passages receive slides secured to the rods whose ends are made of screw pairs for permitting nuts to bear against the passage traverse. The passages are provided with branch pipes for supplying paste-like water mixture. The slides are defined by the cylindrical surface from the side of the measuring section of the pipeline. ^ EFFECT: enhanced reliability. ^ 3 dwg
