GPS-7A Hydraulically Driven shotcrete machine concrete pump
Description:
GPS-7A wet shotcrete machine uses 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.
Output of GPS-7A wet shotcrete machine 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.
Gaodetec equipped self-lubrication system for the wet shotcrete machine to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly.
