With the extensive application of hydraulic technology since the 1930s and the emergence of fault diagnosis technology in the 1960s, Hydraulic Paver the application of fault diagnosis technology in the hydraulic system of asphalt concrete paver has been developed rapidly. Technically, the development of this period has gone through three stages: simple diagnosis technology, fault tester technology, computer fault diagnosis technology. Hydraulic Paver Simple diagnosis technology, also known as subjective diagnosis method, Hydraulic Paver it is based on the fault diagnosis staff to see, listen, touch, smell, ask and other subjective factors on the basis of a strong hydraulic system fault diagnosis. This method can only qualitatively determine the asphalt concrete paver hydraulic system somewhere fault situation, Hydraulic Paver the accuracy is poor. The latter two diagnostic techniques are based on the development of electronic technology and computer technology, also known as the objective diagnosis method, Hydraulic Paver can more accurately and quantitatively monitor the operating state of the system to determine the fault situation. However, the use of fault tester on the asphalt concrete paver hydraulic system diagnosis, must be connected to the test site in advance, Hydraulic Paver the diagnosis is more complicated.

Simple diagnosis technology, also known as subjective diagnosis method, it is mainly based on the fault diagnosis staff to see, listen, touch, Hydraulic Paver smell, ask and other subjective factors on the basis of a strong hydraulic system fault diagnosis. This method can only qualitatively determine the asphalt concrete paver hydraulic system somewhere fault situation, Hydraulic Paver the accuracy is poor.

The latter two diagnostic techniques are more advanced, generally in the development of electronic technology and computer technology based on the emergence of, also known as objective diagnosis method, can more accurately and quantitatively on the system to monitor a running state, thus Determine the fault situation. Hydraulic Paver However, the use of fault tester on the asphalt concrete paver hydraulic system diagnosis, must be connected to the test site in advance, the diagnosis is more complicated.

Check the hydraulic pump is rotating; tank oil is sufficient; oil filter and pipe is blocked.

Check the oil filter vacuum gauge, the pressure at 25kPa when the oil filter; in the pressure circuit on the pressure, such as the pressure is very small, Hydraulic Paver check the replacement of the relief valve. Pump does not drain, replace the pump or pipe; pressure fluctuations, remove the suction pipe intake phenomenon.

Check the fuel tank; oil filter filter pollution; pump and motor operating status.

Replace the oil filter; Hydraulic Paver replace the oil filter; check the relief valve work, depending on the situation to replace it; replace the pump and motor damaged parts.

Paving machine network can provide excellent paver hydraulic system accessories for the majority of users, Hydraulic Paver including filter, Hydraulic Paver hydraulic lock valve block, hopper cylinder, hydraulic oil fan, hydraulic filter, etc.
