YAW-300B microcomputer controlled electro-hydraulic cement pressure testing machine

YAW-300B microcomputer controlled electro-hydraulic cement pressure testing machine

A . Function and structure

⊙ YAW-300B microcomputer controlled electro-hydraulic cement pressure testing machine is mainly used for compressive strength test of cement mortar.

The whole test machine is mainly composed of main engine, oil source electric control cabinet and computer printer. The machine adopts hydraulic loading, oil pressure sensor force measurement, PC -electro-hydraulic proportional control technology to automatically control the test process. The test process is in full compliance with GB/T17671-1999 "Test method for strength of cement mortar" (ISO method) , special computer software realizes full-screen Chinese window display, real-time display test force, test force peak, test force-time curve, Data processing, storage and printing are available.

The main machine of the boring test machine consists of a top beam, a lower beam and two columns to form a fixed frame. The cylinder piston is fixed on the lower beam by screws. The above is the main component of the mainframe and is fixed on the base with screws.
