Four, the main functions and features:
Function:
YAW - 300 - e type microcomputer control of constant stress cement pressure testing machine according to the and GB17671 GB177-85-85 the compressive strength of mortar test method for automatically control by means of a group of six trials, with constant speed test force, constant stress, test the force control mode, etc. Implements the test data, test curve of screen display, disk storage, database management, etc. Products with high precision, good performance, high reliability and convenient operation, etc.
Features:
YAW - 300 - e type microcomputer control pressure testing machine, constant stress cement is a attaches great importance to the basic performance, based on the development of precise testing machine.
With excellent operation performance of the host
A) drive system adopts advanced dc servo motor speed control, speed control than 1:7 00, depending on the speed of loading need to within 0.07-35 mm/min realize arbitrary pressure plate rising velocity;
B) all the mechanical structure, from the servo motor to servo reducer, adopts fully sealed structure, no need to use oil change, there is no pressure oil spills and proportional valve plug;
C) host design according to the man-machine engineering standards, the operation is simple, convenient and quick.
Survey control accuracy and intelligent
A) give full play to the advantages of the microcomputer, reduced the electric control system hardware, all rinou diversity into two modules, make the product reliability is greatly increased;
B) more than the maximum test force a range (overload the gear 2-5%), or piston have limit, can instantly stop;
C) the measurement data can be permanent, so that after the observation;
Test force, displacement measurement control focused on microcomputer test interface, intuitive, easy to operate.
YAW - 300 - e type microcomputer control of constant stress and cement on the host machine is made up of two columns, beams and floor and workbench gantry framework. By dc servo motor, synchronous toothed belt, speed reducer and the precision of lead screw transmission mechanism, implementing mechanical piston to move up and down, so as to realize the movement of specimen pressure plate. To complete the compression test. Including mechanical telescopic cylinder by my company is specialized in design, compact structure, smooth transmission. The agency to ensure rack has enough stiffness and stability, high efficiency. On beams in the process of test, the load sensors to measure the size of the test force, after filtering amplifier, single-chip microcomputer by A/D conversion, single-chip microcomputer test data collection and processing to the microcomputer, microcomputer according to the sensor output signal via operation and then the corresponding control signal to control host machine motor, the whole process for the closed-loop control, each time period of 10 milliseconds control process. At the same time judge overload for treatment and protection.
