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. The 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.
