China Most Popular Small Damp Shotcrete Machine for Shotcrete Project

LPS-7A Wet Shotcrete Machine
Description:
LPS-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.
LPS-7A wet shotcrete machine 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.
Leadcrete equipped self-lubrication system for the wet shotcrete machine to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly.
Application:
LPS-7A wet shotcrete machine used for wet concrete spraying in mine, tunnel, culvert, metro, hydropower engineering, underground construction, slope protection etc. or for filling, grouting pumping concrete mortar etc.
Feature:

1.Use Svalve 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.Main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely.

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.
