| Abstract: | Hydraulic technique has been widely applied in all kinds of machine equipments.The current troubleshooting methods of hydraulic system cannot meet the simple,rapid and accurate requirements of the spot diagnoses,due to the busy and bad technical condition.According to the features of the trouble of hydraulic system as well as the request of the spot diagnosis,the operating principle and troubleshooting steps of the logical diagnosis based on the parameter measure are described.The method combines the advantages of the measure circuit and the logical diagnosis.Hence,it can improve the efficiency and accuracy of the troubleshooting.Furthermore,the method also features a small workload of assembling-and-disassembling,an easy operation and a low cost and therefore provides a scientific and valid method for the spot troubleshooting of the hydraulic system. |
