　　Tunnel 7 type wet spraying machine for construction engineering

　　What is the essential difference between concrete spraying machine and wet spraying machine? The five essential differences between dry and wet sprayers are hoped to be helpful for purchasing sprayers. The dryness and wetness of the slurry are different: the sprayed slurry added by the dry spraying machine is dry, such as concrete, cement, etc., without adding water or with a small amount of water. The wet shotcrete machine adds a uniformly mixed mixture, such as concrete, cement, and water, which is thoroughly mixed and then sprayed out. The spraying mode is different: the dry spraying machine adds dry concrete or cement, so when spraying, the nozzle needs to add water to ensure the spraying effect and not produce too much dust. Wet spraying machine uses water to fully mix concrete or cement, and then sprays it. There is no need to add water at the nozzle, and no dust is generated, ensuring a working environment. The conveying distance and air pressure are different: the conveying distance of dry sprayers can reach over 200 meters, while the slurry sprayed by wet sprayers is already mixed and viscous, so the vertical conveying distance can only reach 20-30 meters, and the horizontal conveying distance is 30-50 meters. The air pressure of the dry spraying machine can reach 7 cubic meters for spraying, while the air pressure of the wet spraying machine needs 13 cubic meters to work.

　　Product features of the spraying machine: straight through rotor type non bonding material chamber, smooth discharge, high efficiency and time saving; Four point elastic compensation compression, good sealing effect, less dust near the machine, and long service life of vulnerable parts; Adopting low-pressure high-speed vortex airflow transportation to overcome problems such as adhesion, pipe blockage, and pulse separation in material transportation, the material flow is uniform, continuous, and stable; The new nozzle and discharge elbow device improve the spraying effect, with less rebound and high spraying layer quality. Maintenance and upkeep of concrete spraying machine: After each shift, the machine must be cleaned thoroughly; Check the fasteners of each component, especially the bolts on the vibrating hopper; Promptly address any issues found at the welding connection; The material chamber inside the machine, the elbow and cone sleeve of the cyclone have a certain degree of anti sticking, but after each shift, they should still be inspected and cleaned, and vulnerable parts should be replaced in a timely manner.
