The main components of the trailer concrete pump are the engine and the oil pump. Trailer concrete pump engine is a diesel engine or motor, is the pump power source. Engine power and main oil pump must work together to maximize equipment efficiency. Based on this principle, constant power computer simulation design and calculation, the system pressure and pump displacement curve is the most reasonable.
The main oil pump is an axial piston variable displacement pump. The output flow is proportional to the driving speed and pump displacement, and there is no step change between the maximum value and the zero value. Pump with constant power control, cut-off pressure and electric proportional flow control. At present, the main pump power powerful, high reliability, long service life, according to load changes automatically adjust the pump displacement. To achieve the purpose of constant power, controlled by the PLC, the output of the main pump is adjusted, that is, the required displacement concrete is pumped and matched with the actual working conditions to ensure the optimal output power of the concrete pump of the concrete pump Or diesel engine.
