What are the operation procedures of the shotcrete shotcreting machine? Henan Hao Li sprayer manufacturers introduced in detail the operation and precautions of the Shotcrete Shotcrete shotcrete.
Second, the operation of the repulsion gun machine 1, before starting, first check the Repulse gun machine parts of the fastening connection is correct and reliable. Start the motor and check that the direction of rotation is correct (same direction as the arrow). Check the pressing force exerted on the rubber plate, first hand-tighten the nut on the compression device rod until it is tight, and then use the plate for 2-3 turns until the rubber plate does not leak. Open the air valve, when the pressure of the feed pipe is about 0.5Mpa, there is no air pressure at the rubber plate, indicating that the fastening degree is just right.
2. Spray the hand-held spray gun towards the wall. The distance between the spray gun tip and the injection site is kept at 0.8-1.2m, and the shotcrete preparation work is well done.
3, before operation, first open the total valve, open the valve on the wind 1/3 turn, adjust the wind to about 0.6-1Mpa air pressure.
4. The sprayer opens the sprinkler water valve and flushes the surface of the prewet rock mass (spray site).
5. Start the shotcreting machine. The loader adds concrete materials to the hopper. When the material is loaded, the continuous and even feeding of the material should be maintained, and concrete spraying operations should be started.
6. When spraying, it is necessary to make up for the first shot after the flat and then the double spray to meet the design requirements.
7, when spraying concrete, the nozzle should be vertical as far as possible by the spray surface, with a spiral ring and evenly move half circle, the diameter of the spray ring is about 200-300mm, each spray width is appropriate to about 1-1.5m.
8. When the sprayer sprays concrete, an assistant shall assist the lighting and signal from the side 5m away from the spray site.
9, stop the injection, to stop loading, first stop the spray machine, until the remaining material in the conveying pipe is blown out without material ejection, you can close the water valve, and finally close the total wind valve.
II. Attentions on the operation of Repulsion Spraying Machine 1. After stopping the machine, the spray gun should be turned upside down to prevent it from flowing into the feeding pipe.
2. After shutting down, the wind pipe and water pipe should be placed neatly, and the sprayer and its surroundings should be cleaned to handle the rebound.
3. If any phenomenon such as blockage or stoppage occurs during the spraying process, stop the machine immediately and turn the pipette tip upside down.
4. When handling a blocked pipe, stop the person in front of the muzzle to prevent sudden injection or pipe-jumping.
5. Each class should clean the rubber sealing plate and check the wear condition.
6, sprayer steel liner must be checked once a week, if there is a deep scribe scratches, it should be re-grinding.
7, spraying machine operators must be trained, qualified certificate holder posts.
