Common problems and solutions in daily use of shot blasting machine

In the daily use of shot blasting machine, occasionally we will encounter some minor faults, such as shot blasting machine cannot be turned on normally, shot blasting machine abnormal noise, etc. These problems are also some common problems. How do we solve them? Let Qingdao Qinggong Machinery will give you an analysis.

1. One or more blast turbines cannot be opened normally.

Possible cause: The thermal relay of the shot blasting device is disconnected or the AC contactor protection switch is disconnected due to overload or motor stuck.  

Solution: Find out the cause and reclose.

2. There is no obvious change in the current of the blast turbine when all the abrasive supply valves are opened.

Reason: No compressed air or insufficient compressed air pressure.

Solution: Check whether the air compressor or centralized air supply is normal.

3. The dust removal fan can be turned on normally, but the other button switches cannot be turned on.

Reason: The horizontal spiral thermal relay is disconnected or the AC contactor protection switch is disconnected due to overload or motor jam.

Solution: Find out the cause and reclose.  

Problem solving during the operation of the shot blasting machine:

First, you can see how shot blasting machine works to have a better understanding of the following three stages.

1. Early stage of shot blasting machine

There are many types of failures that occur at the beginning of operation, and they are more complicated. Such as selection issues, design issues or environmental issues. If the design does not pay attention to the firm connection between the connecting rod and the actuator, the phenomenon of shedding will occur; the power line and the signal line use the same threading pipe during installation, causing relatively large signal interference; there are unshielded electrical equipment nearby, Affects the stability of operation; the internal choke coil of the position locator is damaged. These problems must be observed in time, discovered and dealt with in time, so as to avoid losses.

2. Mid-term operation of shot blasting machine

In the middle of the shot blasting machine's operation, the overall performance of the electric actuator of the shot blasting machine has also changed from the running-in period to the adaptation period, and the performance at this time is relatively stable. If there is a problem, most of the individual electronic components have quality problems. Such as current converters, intermediate contactors, micro switches, etc.

3. Late operation of shot blasting machine  

In the later stage of operation, the aging problems of components and the wear of transmission parts began to become extremely serious. For example, the aging of the motor coils led to the reduction of insulation and unstable operation; poor lubricity of the motor reduced the stability of operation; The aging of the comparison coil or the aging of the position current converter reduces the positioning accuracy; the wear of the transmission parts of the reducer causes the electric mechanism of the shot blasting machine to be unable to adjust, and so on. In addition, there are also reasons such as artificial stepping, process baffle jam, and wrong operation.

The above are the common problems and solutions during the operation of the shot blasting machine. If you have any questions, please feel free to contact us.
