Concrete mixer pump hydraulic system

1.Double open hydraulic loops (pumping hydraulic circuit is independent of distributing hydraulic circuit) with two pumps, makes the whole hydraulic system much simpler. The reliability of the whole system is also much higher as well as the components’ life is prolonged greatly. This is convenient for judgeing and removing trouble. The double pump and double loop open hydraulic system is adopted. The main pumping circuit and the swaying oil circuit of S valve are independent of each other, which makes the system simple, the component life is extended and the reliability is higher.

2.Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability,high reliability and high resist contaminative capability.

3.Hydraulic system has safe relief protection,at the same time,when the system pressure is over, the main oil pump cutting device makes itself be protected reliably.

4.Distributing hydraulic circuit adopts constant pressure pump, which can provide strong distributing pressure and economic energy control.

5.Cone sealing of all pipes make the pipe joints seal reliably.

6.The high-low pressure switch adopting cartridge valve of reduces the trouble of dismantling and installing the oil pipe.

7.Adopt emulsification technology of initiative and passivity recovery integration.
