Best Testing Equipment

 Product Description

YEW-3000A hydraulic direct compression testing machine is mainly used to various materials compression test. Such as cement, concrete, brick of diverse materials, rubber tray, concrete component, metal component anti-compress strength.

     This machine is consisted of load frame, oil source control cabinet, computer and printer etc. It adopts hydraulic load, oil pressure transducer to measure load, manual control the testing process. PC screen display the test data and curve, with data storage and print function, the database file is convenient for user to use them by ACCESS and EXCEL.   

The oil cylinder is at bottom of load frame, movable crosshead can random adjust testing space within a range. The load frame is consisted of crosshead, leading screw, working table and dolly. The crosshead is supported on base by two columns, then tighten by screw cap. On crosshead there mounted sphere base, upper platen is fixed on sphere base. When loading, it can judge the loading direction in accordance with specimen shape to make load uniformity. On crosshead mounted an adjusting motor, the motor drive worm shaft, and worm shaft drive worm wheel, then rotate the screw nut, to realize the moving of crosshead and adjusting of testing space. To support the weight of crosshead, there installed a spring in it, eliminate vertical clearance between nut screw thread and rod screw thread, make the test reliable and data accurate. Oil cylinder and piston are key part of load frame, their interface must be processed precisely, keep certain clearance and oil film. When the high pressure oil enters into oil cylinder, push piston and dolly, lower platen rising, make load consistently on the specimen. Lower platen installed on the dolly, the dolly can move easily on the orbit, it’s convenient to load and unload the specimens.
