Concrete pump and its working principle
Concrete pump is the abbreviation of the trailer concrete pump.
Concrete pump is a kind of mechanical equipment which USES reciprocating linear motion of concrete conveying cylinder to output ready-mixed concrete at higher than atmospheric pressure.
Now the common s-tube valve pumping mechanism to illustrate its pumping principle:
1-fig.(1)working principle of concrete pump
Working state 1: A cylinder suction, B cylinder discharge concrete;
Working condition 2: B cylinder suction, A cylinder discharge concrete.
When the process of state 1 ends, the S-tube will swing to the exit of cylinder A and enter state 2. At the end of the process of state 2, S-tube swings to the entrance of B cylinder and enters state 1...... And so on.
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.
