How to debug the installed multifunctional elastic testing machine?
Debugging the installed multifunctional elastic testing machine, mainly including mechanical, electrical, software and other aspects, the specific steps are as follows:
Mechanical system debugging
Inspection of transmission parts: Manually rotate the transmission parts of the testing machine, such as roller and screw, to check whether the rotation is smooth, and whether there is jamming, abnormal sound or obvious resistance. If problems are found, it is necessary to timely check whether the parts are not installed properly, the lubrication is insufficient or there is a foreign body obstruction, and deal with them accordingly.
Tension system debugging: adjust the tension device, set different tension values, and detect whether the actual tension is consistent with the set value through the tension sensor. If there is any deviation, adjust the parameters of the tension controller or check whether the tension transmission mechanism works normally, so as to control the tension within the specified precision range.
Inspection of friction parts: Check whether the surfaces of friction parts such as rollers and thread guides that are in contact with the silk thread are smooth, and whether there are any abrasion, scratches or burrs, so as not to affect the elastic effect and damage the silk thread. If there is any problem, the friction parts need to be repaired or replaced.
Motion accuracy detection: use precision measuring tools, such as dial indicator, to detect the motion accuracy of all moving parts of the testing machine, such as the radial runout of the roller and the straightness of the screw, to ensure that it is within the precision range specified by the equipment, so as to ensure the stability and accuracy of the silk thread movement during the loading process.
Electrical system debugging
Power supply inspection: measure whether the voltage and frequency of the input power supply meet the requirements of the testing machine, and check whether the phase sequence of the power supply is correct. Use multimeter and other tools to detect whether there are potential safety hazards such as leakage and short circuit in the power supply line to ensure the stability and reliability of the power supply system.
Motor debugging: start each motor of the testing machine, such as main motor and traction motor, respectively, and observe whether the motor turns correctly, runs smoothly, and has abnormal noise and overheating. By adjusting the inverter parameters of the motor, such as frequency, acceleration time and deceleration time, the running performance of the motor can meet the working requirements of the testing machine.
Sensor calibration: calibrate all kinds of sensors on the testing machine, such as temperature sensor, tension sensor and displacement sensor. According to the specifications of the sensor, use standard calibration equipment or methods to perform zero calibration and full-scale calibration on the sensor to ensure the accuracy and reliability of the sensor measurement data.
Electrical control function test: operate the electrical control system of the testing machine, test whether all control buttons, switches, indicator lights, etc. work normally, and check whether the control system controls the motor, heating device, cooling device and other equipment accurately. By simulating different working conditions and faults, the effectiveness of the protection functions of the electrical control system, such as overload protection, short circuit protection, overheating protection, etc., is tested.
Commissioning of heating and cooling system
Debugging of heating system: set the temperature setting value of heating device, start the heating system, and observe whether the heating element works normally and whether the temperature rises steadily. Use temperature detection instruments, such as thermocouple thermometer, to measure the actual temperature of the heating area, and compare it with the temperature displayed by the control system. If there is any deviation, calibrate and adjust the temperature control system to make the temperature control accuracy meet the test requirements.
Debugging of cooling system: start the cooling system, and check whether the cooling water pump, fan and other equipment are running normally, and whether the flow and pressure of cooling liquid meet the requirements. Observe the cooling effect of the cooling system on the heating parts, ensure that the heating parts can be kept in a suitable temperature range during the operation of the testing machine, and avoid overheating affecting the performance and service life of the equipment.
Software system debugging
Parameter setting and optimization: according to the test requirements and material characteristics, various parameters, such as loading speed, temperature, tension and setting time, are set in the control software of the testing machine. By carrying out some preliminary tests, observing the test results, the parameters are optimized and adjusted to obtain the best effect of loading.
Data collection and recording test: Run the testing machine to carry out simulation test, and check whether the software can accurately collect and record various test data, such as temperature, tension, displacement, time, etc. Analyze and process the collected data, check the accuracy and integrity of the data, and ensure that the test data can provide reliable basis for subsequent research and production.
Communication function check: If the testing machine has the function of communicating with other equipment or systems, such as the monitoring system and data management system of the upper computer, check whether the communication interface is connected normally, whether the communication protocol is matched, and whether the data transmission is stable and accurate.
During the whole debugging process, the debugging process and results should be recorded in detail, including the setting and adjustment of various parameters, problems and solutions, so as to provide reference for subsequent equipment maintenance and use.
