6 Test method
6.1 For the test of 5.2.1a, pull a straight line (steel wire with a diameter of less than 1mm) close to two high points on the side of the guide rail, and use a steel ruler to measure the maximum distance between the guide rail and the straight line.
6.2 For the test of 5.2.1b, use a feeler gauge. 6.3 For the test of 5.2.1c, use a height vernier caliper to measure. 6.4 For the test of 5.2.2 and 5.3.9, use
Test;
Operation test, adjust the machine to the working state according to the procedures specified in the product manual, run continuously for not less than 2h, and use the sensory method b.
Load test, load objects with the same mass as the workpiece on the hopper (basket) or conveyor line, run continuously for not less than 2h (can be combined with the operation test), and use the sensory method to test; C. The deviation of the belt (curtain, net) is measured with a ruler. 6.5 For the test of 5.3.1, place the thermometer at 0.5m from the inlet and outlet of the drying tunnel, hot box, atomizing chamber and cold box. After 0.5-1h of starting up, measure once every 10min for a total of three times and take the average value. 6.6 For the test of 5.3.2, select 3 measuring points at 0.5m from the inlet and outlet and the center of the drying tunnel, hot box, atomizing chamber and cold box in the same temperature zone and section. Test according to the method of 6.5 and take the maximum deviation value. 6.7 For the test of 5.3.3, adjust the running speed to low speed, medium speed and high speed, run more than twice (each time, the hopper or hanging basket, conveyor belt should run more than one circle), use a stopwatch to record the running time of a predetermined length, and then calculate according to the following formula. Where: )-…--running speed of hopper and conveyor line, m/min; s-predetermined running length to be passed, m;
t-time required to pass the predetermined running length, min. 6.8 For the inspection of 5.3.4, use the timer to count and calculate. 6.9 For the inspection of 5.3.5, use the hygrometer to test and observe whether there is any dripping. 6.10 For the inspection of 5.3.6, manually adjust the belt at the workstation window and observe whether it is sucked into the machine. 6.11 For 5.3.7. The inspection of Article 5.3.8 shall be carried out in accordance with the methods specified in GB7612. 6.12 The inspection of Article 5.3.8 shall be carried out in accordance with the methods specified in Articles 13.1 to 13.5 of GB/T5226. 6.13 The technical requirements of the remaining articles shall be tested by sensory methods. 6.14 Test methods other than those in this standard may also be used if they can achieve the same evaluation results as above.
