The noise to which the driver is subjected at the operating position shall not exceed 90A)s.
5.2 The dust content at the operating position of the machine shall not exceed 2mg/m6 Test method
6.1 Lift
JB/T 9U23.2-1959
Put the carriage horizontally on the ground, and test it with an electronic force meter without drilling rods and impact screens. The value in the table should be in accordance with the performance value (test under a force of (. stone MPa). 2 Temperature rise of rotary reducer
After the rotary reducer runs for [h, use a thermometer to test the bearing part. 6.3 Noise
Test it with an ordinary sound level meter at the working position of the machine. 6.4 Cleanliness of the rotary reducer box
Pull out the lean gas from the filter, and then inject steam into the box. Use a brush to clean all parts, and remove the living micro-water. Figure 2 Size 1.075mm (2 screen mesh) The sieve is melted, the filtered evidence together with the filter are dried in a box (temperature 130°C for 1h), and then cooled in a desiccant for 20m. The weight of the cut and taken out shall not exceed 960mg. 6.5 Dust content is specified in GB:1692. 7 Inspection rules 7.1 Each pinning machine must be inspected by the factory technical inspection department in accordance with the requirements of this standard before it can be used! And it must be accompanied by a product certificate of qualification 7.2 Each pinning machine shall be subjected to an empty load test for no less than 0.5h: 7.3 The empty load test shall meet the requirements of; a) 4.2, 4.3, 4.4 and 45: 6) The basic parameters shall comply with the provisions of 33: All rotating parts shall rotate flexibly and the fasteners shall be firm. 8 Marking, packaging, transportation and storage
