With the development of the hydraulic pressure industry, hydraulic pressure technology plays a more and more important role in each kind of machine. Since the composition and the function of hydraulic system are complex, troubles increasingly turn up .One of hydraulic equipment shortcomings is that searching the reason is not easy while the trouble is expected to be exist. However, the test equipments for examining the performance parameter of hydraulic pressure parts are often the performance sole hydraulic pressure test platform, and it is generally used by the factory and the research institute for the hydraulic pressure special-purpose, which makes the hydraulic system breakdown diagnosis more inconvenient. Looking from the use aspect, once the hydraulic system breaks down, we need to examine the many kinds of hydraulic pressure part the technical specification, but the performance sole test platform can not fastly effectively discover the spot and the root of the breakdown to repair the goal. For the purpose above, we have designed one kind of hydraulic pressure comprehensive test platform.
This article designed the synthesized test platform by the mission. Designing the system schematic diagram explained the work principle of the hydraulic pressure synthesized test platform; According to the design of hydraulic pump, hydraulic valve, drill tubing choice and the computation, determined the model and the size of the hydraulic pressure part; In order to improving the consummation system, this article also carried on to test the system pressure loss and temperature increment; In addition, through the system calorific capacity computation, completed to choose the heater and the chiller ; Through designing the belt transmission and the axis structural, this article completed to the design of pumping station. This test platform may separately test performance parameter of the hydraulic pump, the hydraulic cylinder and the hydraulic valve. Compares with the special-purpose test platform, it has a-machine-multipurpose merit. In addition, its structure is simple, and the operation is easy, testing is simple and reliable.
