GPS-7A wet shotcrete machine use hydraulic pumping S valve structure, two oil cylinders Reciprocating motion alternately to pump concrete from conveying pipe to nozzle, Add compress air to wet shotcrete machine outlet and add A percentage of the accelerator at nozzle, concrete slurry be sprayed to surface directly. GPS-7A output could be adjusted continuously: main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely. Accelerating adding quantity could be adjusted continuously: according to concrete spraying volume adjust step-less.
1. Use S valve reversing, good sealing performance, longer working life. 2. Equipped floating wearing ring on S valve, could self-compensating wearing. 3. High outlet pressure, could meet the demands of concrete pumping for high building. 4. Hydraulic system adopt air-cooler, easy operate, don’t need water. 5. With reverse function, reduce pipe plugged. 6. HMain oil pump is variable displacement plunger pump, spraying volume could be adjusted freel. 7. Equipped self-lubrication system to automatic lubrication for main sealing parts, lengthen wearing parts working life. 8. PLC control, With wireless remote control, easy to operate. 9. With guide pulley, easy to move, location. 10. Accelerating adding quantity could be adjusted continuously. Application
GPS-7A wet shotcrete machine used for wet concrete spraying in mine, tunnel, culvert, metro, hydropower engineering, undergroun.
