P20D Diesel shotcrete pump


P20D is a kind of mechanical equipment that can be both shotcrete and grouting. The shotcrete uses the thrust generated by the hydraulic pump to make two oil cylinders alternately move back and forth to send the dense flow material from the conveying pipe to the mixed flow pipe. Grouting directly sends the dense flow material to the pouring body from the conveying pipe.
Parameters
  • Production capacity :3-22m³ /h
  • System pressure:22MPa
  • Working wind pressure: 0.4-0.6Mpa
  • Maximum diameter of aggregate: 15mm(shotcrete)/30mm

FEATURES

Stable

The whole vehicle has stable performance, few wearing parts, and low maintenance and use cost.

Wearable

High-manganese steel casting integrated sprinkler, smoother, more wear-resistant, shotcrete pulsation is small, and continuity is good.

PLC Control

The electrical appliances adopt PLC centralized control, which is reliable in work, long in life, and easy to program and operate.

Good continuity

The shotcrete has small pulsation and good continuity. The addition amount of accelerator is steplessly adjustable.
