Adjustable pressure variable output Concrete Pumping Machine hydraumatic
Concrete Pumping Machine
Hydraulic electromagnetic reversing mechanism of Concrete Pumping Machine:
Hydraulic control system, see the figure below (hydraulic schematic diagram) by motor, gear oil pump, electromagnetic reversing valve, relief valve, hydraulic cylinder, oil tank, high pressure oil pipe and other components of the full hydraulic control reversing hydraulic system, the whole oil design optimization, low heat loss, more stable system. The motor and gear pump provide sufficient power support for the hydraulic system, and the pressure of the relief valve is adjustable to provide stable pressure for the whole system.

Working process of Concrete Pumping Machine:
First of all, the concrete pump must be parked on flat, solid ground, absolutely not on soft ground, in order to avoid the inclination in the process of work.
Start the main motor for a short time operation, and observe whether the pressure gauge is normal. According to the length of the pipeline, before starting the construction work, we must first pump the water into the pipeline through the pendulum valve to lubricate the pipe wall. Then mortar, and finally concrete, work begins, and often run the test pump empty, with clear water pumping to confirm the smooth pipeline.
