Hot Sale Used Diesel Type Trailer Wet Concrete Plaster Shotcrete and Cement Pump Machine for Tunnel Construction

Hot Sale Used Diesel Type Trailer Wet Concrete Plaster Shotcrete and Cement Pump Machine for Tunnel Construction

High working efficiency: hydraulic pumping type, high system reliability, stable conveying capacity.Can be used for grouting, filling, grouting, pumping and other construction. Continuously adjustable injection amount: variable plunger pump is adopted for the main oil pump, and the injection speed can be freely adjusted (the maximum number of switching adjustment amount shall not be more than 16 times /min). The additive amount of accelerating agent is continuously adjustable: it can be continuously adjusted according to the amount of shotcrete. Long service life of wearing parts: the service life of wearing parts of the main engine is not less than 4000m3 of injection.

1.Power system concrete plaster shotcrete and concrete pump

Hydraulic oil pump: Germany Rexroth or Japan Kawasaki are adjusted. Diesel power: Germany Deutz, Weichai, Schneider, Japan Siemens, Mitsubishi are adjusted. The main power could be adjusted by the user

2.Electronic control system concrete plaster shotcrete and concrete pump

Japan Mitsubishi Programmable Logic Controller (PLC) electronic control system. Main electric elements are imported original Schneider, Siemens, OMRON, LG etc. The control mode: manual operation and wireless remote control Humanity and intelligent electronic control system optimizes the person-machine interface.8-digital pumping time accumulation timer provides exact data for the user, Automatic anti-pump function and optimized program design. Automatic trouble monitoring function.

3.Hydraulic system concrete plaster shotcrete and concrete pump

The unique open hydraulic system and hydraulic cushion technology contribute to the smaller exchange impact and less heat of the system. Meanwhile, with the famous brand of main pump and hydraulic valve, the safety and reliability of the concrete pump are guaranteed. The hydraulic pipeline selects the high performance seamless steel pipes and all pipe joints and high pressure hoses are of the famous brands. A number of high pressure accumulators and their excellent cushion performance reduce the requirement of S pipe vale for the concrete. The concrete is delivered freely.

4.Pumping system concrete plaster shotcrete and concrete pump

Pumping displacement variable adjustment: Change the pumping displacement according to the construction to meet the requirement of the condition. Reducing design of the hopper could release the reducing pressure of the concrete into the delivery pipe maximally, and prolong the service life of the S pipe outlet.

5.Lubrication System concrete plaster shotcrete and concrete pump

The patented central automatic lubrication system comes with a piston grease-pump, features high pressure and reliability, which can realize automatic lubrication of piston. The filters at the outlet and the inlet of oil ports as double protections guarantee the system reliability.

6.Cooling System concrete plaster shotcrete and concrete pump

Compulsory air cooled heat exchanger keeps the temperature of the hydraulic oil below 60 degree,that ensures the whole hydraulic system works at normal status.
