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

⊙ The test machine consists of a main machine, oil source electric control cabinets and computer printers. The machine adopts hydraulic loading, oil pressure sensor force measurement, PC -electrical fluid proportional control technology, and automatically controls the test process. The test process is in full compliance with the GB/T17671-1999 "Cement mortar strength test method" (ISO method) requirements, special computer software to achieve a full-screen Chinese window display, real-time display test force, peak test force, test force - time curve, Data processing, storage and printing can be performed.

The main body of the tester is a fixed frame consisting of upper beam, lower beam and two columns. The piston of the cylinder is fixed on the lower beam with screws. The above is the main part of the host and is fixed on the base with screws.

⊙ Hydraulic system principle: The role of electromagnetic valve is quick oil return, manual valve group can not only manually control the piston up, down, but also for the electro-hydraulic proportional valve to provide a stable pressure difference, so that the electro-hydraulic proportional throttle becomes The electro-hydraulic proportional speed control valve realizes the parallel connection of the manual control and the automatic control. The specific working process is: the motor drives the oil pump to rotate; the hydraulic oil in the fuel tank enters the oil filter after being pressurized by the oil pump; the filtered oil passes through the manual valve Or the proportional valve controls the flow into the cylinder to control the test process. The valve comes to the oil through the throttle valve into the high pressure oil chamber to seal and reduce the friction between the cylinder and the piston.
