5.2. The machine must be reversed before load operation. Empty run test 5.2.2 Carry out load test according to the design load, and check according to the contents of 4.3 of this standard. 5.3 Shot blasting machine shot blasting amount test
Start the machine, first adjust the shot supply gate so that its frequency shot flow reaches When the shot blasting machine reaches the maximum amount of shot within the power range allowed by the shot blasting machine, and the shot inlet pipe does not discharge the shot, and the shot does not overflow for 15 minutes; after heating, close the shot supply gate, stop the shot supply, remove the micro bucket and the shot inlet pipe, and place a stopwatch under the shot supply gate. During the test, open the shot supply gate and the stopwatch at the same time, close the shot supply gate at 305, and then weigh the net weight of the shot in the container (converted to kg/min). The same method is used to measure twice, and the arithmetic average is taken, which is the shot blasting pass. 5.4 Cleanliness is tested according to the provisions of JB/T5365.1, and 5.5 Noise level is tested according to the provisions of JB/6331.2. 5.6 Dust emission concentration detection a) The measuring instrument is a dust sampler and a full set of accessories. The section of the test plate should be selected at the air inlet of the dust removal system as far away as possible from the fan, air valve, elbow and other components that disturb the airflow and change the direction of the airflow.
Center measurement points are on two mutually perpendicular sampling lines passing through the center line of the pipeline on the measurement panel section. For sections with a straight line diameter less than 1, 2 measurement points can be taken on each sampling line (see Figure 1); for sections with a diameter greater than 1 or poor air flow distribution, 4 or more measurement points can be taken on each sampling line (see Figure 2. Different sampling lines are used for different sampling points. The sampling time is 3min. 2) The dust concentration is the same at each measurement point. The dust concentration is mgm\:
E,——The sum of the dust accumulated on each filter membrane, mgi—The gas production cost of each measuring point under the standard state, m806
5.7 When the manufacturer preconditions to send the whole machine for final assembly test, it is allowed to be carried out in the user's factory. Before leaving the factory, the assembled parts must be tested for empty operation. 6 Inspection rules
