To test the emergency brake function of a cable tray-making machine, it is necessary to conduct a comprehensive test from the aspects of brake response, brake effect, safety, etc. The specific steps are as follows:
1. Preparation before the test: Confirm that the equipment is in a no-load operation state and turn off unnecessary auxiliary systems; Check the appearance of the brake device to see whether the brake pads, brake rods, and other parts are worn, deformed, or loose.
2. Brake response test: Press the emergency brake button when the equipment is running at a low speed, and use a stopwatch or high-precision timer to record the time from pressing the button to the complete stop of the equipment. The normal response time should be less than 0.5 seconds; repeat the test many times to ensure that the response time is stable each time.
3. Braking effect check: After the braking is completed, check whether the moving parts of the equipment are completely stopped, and the rollers, conveyor belts, etc. must not have inertial sliding; measure the sliding distance of the equipment after braking, which should be controlled within 10 cm.
4. Electrical system detection: Use a multimeter to detect the emergency brake circuit to ensure that the circuit can quickly cut off the main power supply after the brake is triggered; check the brake signal record of the PLC control system to confirm that the signal transmission is normal.
5. Reset function test: After braking, reset the equipment according to the standard process to check whether it can restart normally; test whether the operating parameters of the equipment are restored to the initial setting value after reset.
6. Safety verification: simulate emergency situations to trigger emergency braking multiple times to observe whether the equipment will have loose parts, abnormal sounds, etc.; check whether the safety protection devices (such as protective doors, and light curtains) are started synchronously during braking.
7. Record and report: record the time, data, and abnormal conditions of each test in detail to form a test report; repair and handle the problems found in the test in time, and retest until they meet the standards.
