Some use of circular powder screening troubleshooting

Some use of circular powder screening troubleshooting

The thickness of flour has a certain influence on the quality of flour. In the production process of flour, the thickness of flour is still to be inspected. The round powder screening according to GB/T5507-2008 new national standard or the new national standard The powder tester was used to perform the operation. Through the long-term use of the laboratory personnel, it was found that the following problems were likely to occur during the use of the powder test sieve during use. The statistics of the solution method were as follows:

Phenomenon: The powder test sieve can operate, but the noise is too loud. Possible causes and maintenance methods: 1. One or more screws in the three-bar linkage are loose, and the screws should be tightened; 2. After a certain period of time, the clearance of the small E18 connecting rod bearing should be replaced; 3. Use for a period of time. After that, the inner diameter of the connecting rod bearing seat becomes larger and should be replaced. 4. The screws fixing the connecting rod bearing should be tightened separately. Symptom: The power indicator is off. Possible causes and maintenance methods: Poor contact of the power connector. Phenomenon: Press the start switch to switch the instrument. Possible causes and maintenance methods: 1. The time controller number does not display or show the number does not change the time The controller socket is in poor contact, the time controller is bad, or the fuse is broken; 2. The time controller number shows and changes; the motor is bad, the motor The starting capacitor fails and should be replaced. 3. The three-bar linkage is not on a plane when it is rotating, and the tray is stuck. 4. The pan gearbox stalls.

Circular powder screening sieve is based on the national standard GB/T5507-2008 "grain and oil inspection powder thickness determination" independent research and development of the powder thickness fineness test sieve. Different sieves have different mesh sizes, so after passing through the sample of the circular powder sieve, different particle separations can be achieved. Then calculate the thickness of the powdered grain according to the amount of residue on the sieve. The specifications of the circular powder screening screen are divided into the specifications of the screen: CQ: 10, 16, 20, 27; CB: 30, 36, 42; the revolving diameter is 50mm and the revolving speed is 260r/min.
