Weicheng Universal Testing Machine ControllerAs the core control unit of material mechanics testing, it undertakes key tasks such as parameter setting, data acquisition, and operation regulation. Its stability directly determines the testing accuracy and equipment life. Combining its electromechanical integration characteristics, maintaining it from the dimensions of standardized operation, environmental adaptation, and system maintenance is the core of extending its "life". The specific "secrets" are as follows.
Standardizing start stop and operation operations is the primary step in circuit protection. Before starting up, it is necessary to confirm that the power supply voltage is stable within the range of 220V ± 10%, and check whether the power line and data line interfaces are firm and not loose, in order to avoid poor contact and circuit impact; When starting, follow the sequence of "main power first, controller later". Wait for the system self-test to be completed (usually around 30 seconds) and no error prompts before loading the test parameters. Do not skip self-test and directly operate. During the testing process, sudden changes to key parameters such as loading rate and range are strictly prohibited to avoid damage to the servo control module caused by instantaneous current fluctuations; Before shutting down, it is necessary to first save the test data, perform the "unload reset" operation, wait for the mechanical structure to return to its original position before turning off the controller power, and finally cut off the main power to prevent residual current from corroding the components.
Reasonable regulation of load and parameter matching is the core guarantee. The appropriate range should be selected based on the strength characteristics of the test material, and overloading beyond the range is strictly prohibited - for example, when testing steel with a tensile strength of 500MPa, modules with a range of 200MPa should not be used to avoid triggering the protection mechanism due to controller overload, as frequent overload will accelerate the aging of the power module. When setting parameters, it is necessary to ensure that the loading rate matches the sampling frequency. For example, when conducting elastic modulus testing, the loading rate should be controlled between 0.5-5mm/min, and the sampling frequency should be set to 100Hz to prevent data overflow and system lag. In addition, to avoid long-term continuous full load operation, the machine should be stopped for 30 minutes every 4 hours of continuous testingWeicheng Universal Testing Machine ControllerAdequate heat dissipation of internal components reduces accumulated high-temperature losses.
Optimizing the operating environment is the key to reducing external losses. The controller should be fixedly installed in a well ventilated laboratory, with a reserved heat dissipation space of at least 15 centimeters on the back and sides of the body to avoid close contact with the testing machine host or other heating equipment. The ambient temperature should be controlled between 5-30 ℃, and the relative humidity should be ≤ 75%. Dehumidifiers should be equipped in humid areas to prevent circuit boards from getting damp and rusting; At the same time, stay away from dust and corrosive gases (such as acidic and alkaline volatiles in chemical laboratories). If dust is generated during testing, a dust cover should be installed around the controller. In addition, avoid direct sunlight or strong electromagnetic interference (such as high-voltage equipment, welding machines) to prevent screen aging or circuit signal disorder.
Regular maintenance and system upkeep should not be relaxed. Wipe the body with a dry soft cloth after daily use, and clean the dust in the heat dissipation holes with a hair dryer's cold air setting every month to prevent blockage and affect heat dissipation. Conduct interface inspection once a quarter, wipe the power and data interfaces with C ₂ H ₆ O to remove the oxide layer; At the software level, test data needs to be backed up monthly and updated every six monthsWeicheng Universal Testing Machine ControllerUpgrade firmware to the latest version and fix system vulnerabilities. When not in use for a long time, the power should be disconnected and covered with a dust-proof and moisture-proof cover. Every 2 months, the device should be powered on for 30 minutes to activate the capacitor and battery and avoid component failure. If an error message appears, the machine should be stopped immediately and professional after-sales service should be contacted. Disassembly and repair are prohibited to prevent secondary damage.
