YAW-300C fully automatic cement flexural and compressive testing machine
YAW-300C fully automatic cement flexural and compressive testing machine is used forThe compressive and flexural test of cement mortar strength in compliance with the GB/T17671-2021 standard adopts a dual-station test space, which is dual-purpose and saves space., simple operation and other advantages.Use microcomputer to realize electronic measurement,Automatically complete the compressive strength test, automatically calculate and print reports, widely used in the construction industry and cement production companies.
Hydraulic system
This machine uses double oil cylinders, with high control accuracy and measurement accuracy.The hydraulic oil in the tank drives the high-pressure pump through the motor and enters the oil circuit. It flows through the one-way valve, high-pressure oil filter, differential pressure valve group, and servo valve before entering the oil cylinder.The computer sends a control signal to the servo valve to control the opening and direction of the servo valve, thereby controlling the flow into the cylinder and achieving constant velocity test force control.
Force measuring system
Using high-precision amplifiers and A/D converters, the whole process is not divided into stages, and the load, peak value, loading speed and intensity are displayed in real time;
Use PID closed-loop control strategy to achieve constant speed loading and display the loading curve in real time
Automatic interval timing and continuous testing;
Querying and printing test results are flexible and convenient;
safety protection device
When the test force exceeds 3% of the maximum test force, overload protection occurs and the oil pump motor stops.
When the piston rises and reaches the upper limit position, the limit protection occurs and the oil pump motor stops.

Test software: with data collection, processing, analysis, storage and display.
User management: You can create and edit users, with dual permission management functions.
Control mode: manual control.
Powerful analysis and processing functions:
Commonly used curves can be selected (stress-strain, load-deformation, load-time, load-displacement, displacement-time, deformation-time and other curves), and the curves can be partially enlarged (stepless amplification, no binning), traversal, moving center points, automatic identification of feature points (elastic sections, yield points, etc.), multiple overlays, and also supports manual marking, result comparison, print preview, and manual effective data revision.
