Is test point adaptor necessary for hydraulic system?

The hydraulic system is very complicated.

During the flow of hydraulic oil, the erratic flow direction and flow rate of the liquid are difficult to predict, especially for the long distance. For such a complex hydraulic system, the system is difficult to debug and maintenance is inconvenient.

Therefore, this feature should be fully considered in the design process, and various possible means should be used as much as possible to improve and enhance the performance of the system.

The application of pressure test point in the hydraulic system is helpful to the debugging of the system. And it can improve the working performance of the system.

1. The application of pressure test point is helpful for system fault diagnosis

The hydraulic system inevitably has various faults during the working process, and the reasons for the faults are often very complicated. The abnormal working of the hydraulic motor is one of these complicated faults.

The reason for the abnormal working operation of the hydraulic motor is complicated. It can be caused by the blockage of the hydraulic or hydraulic pipeline, or it may be caused by the failure of the load or the hydraulic motor itself.

Once a failure occurs, quickly identifying the cause of the failure is the key to troubleshooting.

Install a pressure test point at the oil inlet of the hydraulic motor, it will help judge the possible cause by testing the pressure of the oil inlet of the hydraulic motor.

It will be very beneficial to find out the cause of the fault and even quickly eliminate the fault.

2. The application of pressure test point is helpful to the adjustment of system pressure.

 In the conventional design, the oil pump outlet of the hydraulic system is equipped with a pressure gauge.

The pressure gauge is not only a measuring tool for adjusting the maximum working pressure of the oil pump outlet, but also a monitoring tool for the working pressure of the hydraulic system.

 Due to the special characteristics of the hydraulic pipeline system such as long oil flow distance, liquid flow direction and flow rate change in the middle, the actual working pressure of the hydraulic motor and the outlet pressure of the oil pump may be far apart.

Through the oil pump outlet pressure gauge it is difficult to debug the actual working pressure of the hydraulic motor and the detection of the working pressure of the hydraulic motor, so the pressure adjustment when the hydraulic motor is working becomes very difficult.

And at the same time, it is impossible to make the hydraulic motor work under the appropriate pressure, which will inevitably affect the working performance of the hydraulic system  and the working state of the hydraulic motor.

 If a pressure gauge is installed directly at the oil inlet of the hydraulic motor, although the working pressure of the hydraulic motor can be measured, it will increase the cost of the hydraulic system. Moreover, the choice of the installation position of the pressure gauge, as well as the working environment and service life are all difficult to guarantee. If a pressure test point is installed at the oil inlet of a hydraulic motor, the situation is different.

Since the pressure test point is very close to the hydraulic motor, the pressure measured basically reflects the working pressure of the hydraulic motor, which will help the accurate adjustment of the working pressure of the hydraulic motor. At the same time, the cost of the pressure test point is relatively low, the installation location is easy to choose, it is not restricted by the working environment, and the service life is long.It can completely avoid the various problems of installing the pressure gauge at the oil inlet of the hydraulic motor.

3. The application of pressure test point helps to improve the working performance of the system

Hydraulic shock is inevitable in the process of hydraulic work, and hydraulic shock is very harmful to the normal operation of the hydraulic system. Avoiding or reducing hydraulic shock as much as possible is a problem that must be considered in the hydraulic system design process.

There are many reasons for the hydraulic shock, including the sudden change of the liquid flow direction and the mixing of air bubbles in the hydraulic oil. Then we can fix the pipe by using the hydraulic pipe clamp to avoid severe vibration, and set the air bubble filter metal mesh in the oil tank. And by extending the distance of the liquid flowing in the tank to make the bubbles gradually seep out, try to avoid the sudden change of the liquid flow direction.

Therefore, it is a good choice to install a pressure test point in the hydraulic pipeline. The pressure test point can be used to release the gas gathered in the higher part of the hydraulic pipeline, so as to compensate for the low rate of bubble leakage in the oil tank and reduce hydraulic shock. It is very beneficial to improve the working performance of the system.

In summary, the proper application of pressure test point in hydraulic systems generally has more advantages than disadvantages. It is very useful for fault diagnosis, debugging and performance improvement of hydraulic systems.
