Henan Hao Li spraying machine manufacturers friendly tips, spray gun in the working process of the security warning is as follows:
1. During the operation of the spraying machine, it is forbidden to use a long stick to clean the material cavity so as to avoid serious damage.
2. When cleaning the machine, it is forbidden to wash the electric control box, vibration motor and main motor with water, so as to avoid the short circuit of the line and affect the normal operation of the machine.
3. When used in downhole production of coal mines, the parts and components in the Schedule of controlled parts of the safety standard shall not be arbitrarily replaced by the user.
4. In the process of using the spraying machine, prevent the longer and bigger objects such as steel bars, iron plates and other debris from entering the rotor material cavity to prevent damage.
5. When the spraying machine is performing shotcrete work, if there is no material ejected at the nozzle, there are generally two situations:
The first occurred when the pipe was about to be blocked. At this time, although the feeding pipeline was not blocked, the feeding condition inside the feeding pipeline deteriorated. In this case, the vibrator should be turned off and the mixing in the feeding pipeline should be stopped. When the material is sprayed out, the pressure in the pipeline returns to normal operating range and then opens.
The second is the occurrence of plugging and the feeding pipeline has been blocked. At this time, the machine should be shut down, and then the feeding pipeline should be cleaned. When it is confirmed that there is no fault in the pipeline, restart the spraying machine to resume normal operation by pressing the start-up operation program. .
Therefore, special attention must be paid when using a spraying machine to avoid dangerous things during work.
