Buying a wet concrete sprayer shotcrete system with shotcrete arm is important, but it is also important to maintain and properly operate the wet concrete sprayer shotcrete system with shotcrete arm, which can extend the service life and service life, as well as ensure safety during the construction process. How do we safely operate the wet concrete sprayer shotcrete system with shotcrete arm?
1. Wet shotcrete system with shotcrete arm operators must be trained before they can operate independently and pass the exam before they can take up posts.
2. During construction, the wet shotcrete system with shotcrete arm must be placed in a safe place and placed smoothly. All wheels must land.
3. When connecting the power cable, you must first turn off the power switch and check if the cable is damaged. The cable must be suspended and must not be placed in the water.
4. Before starting the machine, check whether there is foreign matter in the hopper and whether the water in the cylinder cooling water tank is sufficient and clean.
5. Before the injection, check whether the system air pressure is sufficient, whether the voltage is in the qualified range, whether the tie rod pressing force is appropriate, whether the rotor is running in the correct direction, whether the vibration motor and the metering pump are normal, and whether the accelerating agent pipeline is open.
6. The language, gestures, and signals must be agreed with the squirt before spraying.
7. During the spraying process, it is necessary to observe the changes of the work wind pressure at any time, and keep in touch with the spray hand at any time, and timely adjust the air volume and the dosage of the accelerator according to the situation.
8. The jet pipe plugging during injection should be handled in time. During processing, the high pressure air should be turned off to control the nozzles to prevent the residual air from ejecting or ejecting the pipe when the ejector is dredging, causing casualties and property losses. When releasing the quick connector, it should be slow and can’t be released once to avoid remaining gas hurt.
9. When the quick-setting coagulant pipeline is blocked, it should be treated in time. When handling, high-pressure air should be closed first, and the direction of the quick-release coagulant leakage should not point to the person. When loosening the connecting nut, it should be slow and cannot be released once to avoid the excess air speed. The coagulant spray wounded.
10. When the injection is stopped, use a high-pressure air to blow the spray pipe and the accelerating agent pipe. If the time between two injections exceeds 30 minutes, use a water-washing wet sprayer, an injection pipe, and an accelerating agent pipe.
11. When cleaning the wet shotcrete system with shotcrete arm, avoid splashing the electrical components with water.
12. After cleaning the wet shotcrete system with shotcrete arm, the pressure plate and hopper should be reset to cut off wind, water and power.
