Hydraulic pressure is relying on liquid pressure can do work in a way of energy transfer and control, as we all know, due to the hydraulic system has a very high power to weight ratio (the same weight can transfer the energy), the use of industrial machinery and walking machinery, respectively, known as industrial hydraulics and walking hydraulics, due to technological advances, more and more of the hydraulic transmission instead of the other transmission mode (mechanical transmission and electric transmission).

The volumetric efficiency, mechanical efficiency and leakage characteristics of the hydraulic pumps, the operational sensitivity of the hydraulic valves, the coordination of the valves, the volumetric efficiency of the motors, the leakage of the cylinders and so on are all parameters that must be known during the process of the products leaving the factory. A variety of factory test report is of course the customer must require technical information. The following is a test report of a valve, the corresponding test equipment can quickly include various technical indicators and generate curves, the customer's needs are reflected.

Due to the complexity and inaccuracy of fluid mechanics, the unknown characteristics of the material determines the hydraulic is an experimental science, in the research and development phase, from the fatigue test of the material, to the hydraulic components (pumps, valves, motors, cylinders, hydraulic accessories, etc.) fluid performance test, the indicators are inseparable from the test, without the test of the hydraulic components is unknown, the performance parameters of the fuzzy, a lot of specific indicators are Uncertainty, but only after many tests and changes in design ideas and design methods, the combination of all relevant elements, it is possible to create a possible excellent product. Just like the following equipment all noise sources are fully shielded, which is very necessary for the noise detection of the pump or motor.

In the repair environment, a problematic hydraulic pumps, valves, cylinders, or motors, etc. If you can get on the debugging is very easy to find out where the problem is, especially in the construction machinery hydraulic system, there is a problem if you have the ability to detect individual components can quickly determine the problem components, because now the hydraulic system is quite complex, the same is held back the car, pumps, valves, oil filters, etc. may be caused, if blindly Doubt that a part of it is obvious that if the operation is not appropriate will expand the fault, so that the original components have no problem to become a victim, into the problem components, at this time if the components are suspected of isolation into a monitored system inside the check, this situation is equivalent to a fracture of a person into the right hospital expert outpatient clinic as well as through the X-ray to detect the problem.

Thus, a solution can be obtained that is accurate and does not amplify the problem. Many masters are very experienced, but now more and more complex systems and controls even if the host plant debugging masters may not fully understand, through the appropriate testing equipment to detect and adjust the host of technical parameters required is of course very necessary, such as the motor's counterbalance valve adjustment is so, debugging the whole car sometimes even become extremely difficult, such as the hydraulic pump constant power adjustment, load-sensitive valves, differential pressure adjustment and so on. Adjustment of load-sensitive valves, etc. A simple motor test setup such as the one below can be a great help for secondary remanufacturing or repair.
