In the production and engineering quality testing of building materials such as cement, concrete, and mortar, compressive strength and flexural strength are the core indicators for measuring material performance. Traditional testing methods often require separate equipment for bending and compression resistance, which not only occupies laboratory space, but also has efficiency bottlenecks such as cumbersome fixture switching and long group testing time. Jinan Xinguang Testing Machine Manufacturing Co., Ltd.'s microcomputer controlled electronic bending and compression integrated machine series highly integrates both bending and compression testing functions, providing more efficient, accurate, and economical integrated testing solutions for building materials production enterprises, quality inspection agencies, and engineering laboratories.
The Xin Guang microcomputer controlled electronic bending and compression resistant integrated machine adopts an AC servo motor drive+precision ball screw transmission technology solution, which completely solves the inherent defects of zero position covering, low-speed crawling, and poor stability in static control of electro-hydraulic servo control. The equipment highly integrates both flexural and compressive testing functions, eliminating the need for repeated disassembly and assembly of fixtures. Switching tests only requires one click operation, and one device can meet the full process testing requirements for the flexural strength of cement mortar and compressive strength of concrete test blocks.
Compared with traditional electro-hydraulic servo pressure testing machines, the Xin Guang microcomputer controlled electronic bending and compression resistance integrated machine has the following outstanding advantages:
1. The measurement range of experimental force is wider, more accurate, and more stable
The electro-hydraulic servo control valve has a zero position covering problem during static control (an inherent characteristic of the electro-hydraulic servo valve itself), coupled with sealing and friction problems in the oil cylinder, the output near the zero position is not linear, prone to crawling at low speeds, poor stability, high initial pressure, and cannot achieve output control of small deformation and small test force. The Xin Guang all-in-one machine adopts AC servo motor combined with ball screw control, which does not have the above problems. With high-precision load sensors for force measurement, the test force measurement range is wider, more accurate, and more stable.
2. Low noise during the experimental process
The noise of the communication servo motor is significantly lower than the working noise of the hydraulic pump, making the laboratory working environment quieter and more comfortable.
3. The control process is not affected by temperature, and the performance is more stable
The electro-hydraulic servo system is greatly affected by changes in oil temperature, while electronic servo control has no such problem and maintains stable performance throughout the year.
4. No pollution caused by hydraulic oil running, emitting, dripping, or leaking
Completely bid farewell to the hidden danger of hydraulic oil leakage, and make the laboratory cleaner and more environmentally friendly.
5. High long-term reliability and maintenance free use
No need to regularly replace hydraulic oil, no need to worry about servo valves being contaminated and stopping working, greatly improving reliability, and requiring no maintenance for long-term use.
Product features and structural characteristics
1. Double column frame structure, stable and reliable
The testing machine adopts a double column frame structure, with the upper pressure plate installed on the upper fixed crossbeam, and the lower pressure plate loading the sample upwards under the action of the driving screw. The AC servo control and transmission system are installed at the lower part of the host. The overall structure is simple and clear, with high reliability.
2. Wide speed range, smooth and efficient testing process
Using Taiwan Dongyuan AC servo speed control system, high-precision and high-frequency AC servo motors are controlled to drive precision ball screw pairs for testing, which can achieve large-scale adjustment of testing speed (0.01-50mm/min), and the testing process is smooth and efficient.
3. Intelligent control system, one click completion of group testing
Using a liquid crystal display controller, the experiment is conducted according to national standards, independently completing the setting of experimental parameters, control of the experimental process, data acquisition, processing, analysis, and display. It can achieve both single specimen testing and group testing - continuously and automatically completing the flexural or compressive testing of 6 cement test blocks, greatly reducing the batch testing time.
4. Data networking with traceable quality
According to customer requirements, an external PC can be used to collect and process test data, output and print various required test curves and reports, and achieve storage and printing networking functions, meeting the requirements of modern laboratory information management.
5. Multiple security protections
It has the function of returning to the initial position after the experiment is completed, which is efficient and fast; Equipped with limit protection and overload/overcurrent protection for the working position, reliable and safe.
