How to install the breaker

2022-05-09

In many links, for the convenience of use, in addition to the necessary excavation applications, the excavator can also be installed with a breaker to carry out crushing and dismantling work, but the installation of this special equipment is a technical task, and it will be damaged if one is not careful The overall fuselage of the excavator, let's follow us to understand the reasonable installation method.

The equipment is connected with the excavator by means of a separation valve. The separation valve has 4 oil holes, and each oil hole has a corresponding mark, which are "p", "a", "h" and "t" ports. . Now the connection method of yc260, yc460, yc750 breakers matching the separation valve on the excavator in the same phase is introduced as follows.

(1) Connect the "p" port of the separation valve and the oil outlet of the pump to each other with a hose.

(2) Connect the "a" port of the separation valve and the oil inlet of the control valve to each other with a hose.

(3) Connect the "h" port of the separation valve to the oil inlet pipe of the special equipment.

(4) Connect the "t" port of the separation valve to the fuel tank.

(5) Connect the oil return pipe of the breaker to the main oil return pipe of the excavator.

(6) The diameter of the pipeline connecting each interface is: when the capacity brought by the host is less than 70l\/min, the diameter of the pipeline is ¢16 mm; when the capacity brought by the host is greater than or equal to 70l\/min, the diameter of the pipeline is ¢20mm.

In this way, after the installation is completed, regular maintenance and maintenance of the special equipment and excavators are required. The excavator can be used for a longer period of time. However, in the process of using the breaker, there can be no emptying and pressing. If the piston rod is not moving in a straight line at a constant speed inside the cylinder, it is easy to cause scratches or wear on the piston rod, which will immediately interfere with the use period.
