About twin-pump twin-circuit hydraulic system of concrete pump
Twin-pump twin-circuit advantages: convenient fault diagnosis, convenient maintenance. And it is beneficial to extend the service life of oil pump.
The pressure oil of the main pump is supplied to the pumping circuit, and the pressure oil of the constant pressure pump is supplied to the reversing circuit, which is called "twin-pump twin-circuit".
This is shown below.
Open and closed system
Open system: the oil flow of the hydraulic system circulates through the tank.
Closed system:the oil flow of the hydraulic system circulates not through the tank.
Schematic diagram is as follows:
