ABG423 paver hydraulic oil temperature is too high solution

Two ABG423 paver in use process, found in varying degrees to appear hydraulic oil alarm phenomenon, in high temperature weather, this phenomenon is particularly obvious. Therefore, the staff of the two paver technical transformation.

1. Clean the engine and refit the intake

The two is mainly responsible for the paver paving modified asphalt, modified asphalt and soot deposits compared with ordinary asphalt concrete is more viscous, so the engine and hydraulic oil radiator radiator often covered with asphalt dust, affect the cooling effect, which requires maintenance personnel often clean the engine. In order to solve this problem, we installed an air duct to the inlet of the asphalt concrete hopper to make it open back, basically avoiding the deposition of asphalt dust on the engine.

2 、 add radiator to the hydraulic circuit

There are three loops in the hydraulic system of ABG423. After repeated calculations, with reference to the working environment temperature, hydraulic oil flow, installation size, system pressure and other parameters, we selected the T2 series radiator produced by ABG company. The technical parameters of the radiator are shown in table 1:

The radiator has the advantages of reasonable size, simple installation and good heat dissipation effect. After installation, it meets the design requirements.

After technical modification, in high temperature environment in the construction of the two sets of paver hydraulic oil alarm phenomenon does not appear, the basic solution in high temperature and high load operating conditions, ABG423 paver hydraulic oil is too high.
