Common troubleshooting of artificial turf abrasion testing machine

　　Artificial turf abrasion resistance testing machineAs the core equipment for testing the durability of lawns, long-term exposure to high-frequency friction and load operation can easily lead to faults such as transmission lag, data deviation, and shutdown alarms. Timely troubleshooting and resolution of these issues are key to ensuring detection accuracy and equipment lifespan. The following outlines common faults and their solutions from the three core systems.

1、 Transmission system malfunction: lagging, abnormal noise, and abnormal speed

1. Fault phenomenon: The wear-resistant grinding head is stuck or the speed is lower than the set value

Troubleshooting steps: First, check the tension of the transmission belt. If the belt is loose (the amount of belt sagging when pressed by fingers exceeds 10mm), adjust the position of the motor bracket and tighten the belt; Next, disassemble the connecting shaft of the grinding head and check if there is any clearance in the bearing due to wear (shake the grinding head by hand, if the radial clearance exceeds 0.5mm, it needs to be replaced); After checking the motor carbon brush, if the wear of the carbon brush exceeds 1/3, it is necessary to replace it with a carbon brush of the same model (it is recommended to use copper graphite material, suitable for high-frequency loads).

2. Fault phenomenon: Sharp abnormal noise occurs during operation

The focus of the investigation is on the gearbox and grinding head components: open the gearbox cover, check the lubricating oil level (if it is lower than the oil mark, add No. 46 extreme pressure gear oil), and observe whether there is wear or tooth breakage on the gear tooth surface (slight wear can be repaired by grinding, and if it is severe, the gear set needs to be replaced); If there is abnormal noise from the grinding head, it is necessary to check whether the fixing bolts of the abrasive are loose, and whether the abrasive is subjected to uneven force due to excessive wear (replace the abrasive in a timely manner to ensure the balance of the grinding head).

2、 Detection system malfunction: data deviation and sensor alarm

1. Fault phenomenon: Poor repeatability of wear detection data

First calibrate the weighing sensor (loaded with standard weights, if the displayed error exceeds ± 0.1g, it needs to be recalibrated through the equipment calibration program); Check the lawn fixing fixture again. If the fixture is loose and causes the lawn to shift, adjust the fixture pressure (the pressure of the pneumatic fixture should be maintained at 0.4-0.6MPa, and the torque of the mechanical fixture should be controlled at 15-20N · m); In addition, environmental humidity exceeding 60% can easily lead to weight detection deviation, and it is necessary to activate the dehumidification function of the equipment or place desiccants in the detection area.

2. Fault phenomenon: Frequent alarm of displacement sensor

Check the distance between the sensor probe and the lawn surface (standard spacing is 5-8mm, too close is prone to collision, too far is prone to false alarm), adjust the probe position, and recalibrate the zero point; If the sensor cable is damaged or has poor contact, the shielded cable needs to be replaced (to avoid electromagnetic interference); If the alarm is still frequent, check the internal circuit of the sensor. If there is component aging, replace it with a displacement sensor of the same model (it is recommended to use a laser displacement sensor with an accuracy of ± 0.01mm).

3、 Control system malfunction: shutdown error and program lag

1. Fault phenomenon: The device stops immediately after starting and displays "overload"

Check if the load on the grinding head exceeds the rated value of the equipment (usually 50-100N, which can be viewed in real-time through the control panel). If the load is abnormal, clean the entanglement of the grinding head or adjust the contact area of the abrasive; Next, check the overload protection relay. If the relay trips, wait for the equipment to cool down and manually reset it (if it trips frequently, check if the motor power matches or replace it with a higher specification relay).

2. Fault phenomenon: The operation interface program lags or does not respond

Turn off the device power first, wait for 30 seconds, and then restart to clear any temporary system faults; If the restart is ineffective, check if the data connection cable is loose (re plug and unplug the communication cable between the industrial computer and PLC); If the program still malfunctions, it is necessary to restore the factory settings through device backup (export the stored detection data before restoration to avoid loss), and if necessary, contact the manufacturer to update the control program.

In daily maintenance, it is recommended to clean the transmission components of the equipment and replenish lubrication every week, calibrate the sensors once a month, and conduct a comprehensive inspection of the equipment circuit and mechanical structure every quarter, which can significantly reduce the occurrence rate of failures and ensureArtificial turf abrasion resistance testing machineLong term stable operation provides reliable data support for lawn quality inspection.
