Classification and troubleshooting methods for hydraulic transmission system faults

1. Abnormal pressure. Regarding hydraulic transmission systems, one of them is the system pipeline. Therefore, in the specific design, it is necessary to reserve some pressure measurement points, and the measurement of pressure data needs to be completed by a pressure gauge. Then, it is necessary to compare the data with the standard values, that is, to identify the cause of the fault. At the same time, I have an understanding of the relevant hydraulic components.

2. Abnormal speed. For hydraulic transmission systems, speed needs to be well controlled in specific operations, but in unexpected situations, it can affect speed. For speed measurement, it is often necessary to measure relevant data, including regulating valves, throttle valves, speed regulating valves, variable pumps, variable mechanisms, etc. At the same time, it is necessary to measure the speed range of the actuator. After the measurement is completed, compare these data.

3. Abnormal actions. At the beginning of operation, any directional valve needs to be switched. Then, we need to observe and record the actions of the actuator in a timely manner. Once any abnormal situation occurs, it indicates that the directional valve used is abnormal. At this point, what we need to do is to carefully check the sequence of actions and control over strokes, in order to identify any anomalies.

Check for faults in the hydraulic transmission system. As for the hydraulic transmission system, it often causes some malfunctions. Therefore, it is necessary to carefully inspect and analyze the fault, then identify the cause of the fault and eliminate it as soon as possible. For systems, before a malfunction occurs, there are often some prompts that, once accumulated to a certain extent, will explode. Through analysis, it can be seen that the reasons for its failure are multifaceted, but there is no certain regularity. In order to better diagnose the cause of faults, we should first understand the characteristics and patterns of hydraulic system faults.

1. Direct inspection method. For the direct inspection method, which involves maintenance personnel analyzing the cause, it is mainly based on their own feelings, experience, or using simple tools to identify the cause of the malfunction.

2. Instrument testing methods. Instrument detection method refers to the use of instruments and meters for inspection based on the characteristics of faults. During the inspection, the hydraulic system mainly adopts a speed through type, and the main inspection contents include flow rate, pressure, oil temperature, hydraulic components, etc. In addition, an analysis was conducted on relevant aspects, namely vibration noise and wear particles.

3. Element replacement method. For component replacement methods, spare parts are used to replace faulty components. Then observe the condition of the hydraulic system to see if there are any faults. Finally, identify the location and cause of the fault and troubleshoot it.

4. Periodic testing methods. In order to monitor and diagnose in a timely manner, it is necessary to arrange the measurement time in detail. In the implementation process, many aspects need to be considered, including: what type of machinery, what is the inspection content, and what is the inspection time. Based on this, the technology of testing relevant components can quickly eliminate hidden dangers.

Hydraulic transmission system fault prevention
1. In order to avoid malfunctions in the hydraulic transmission system, it is necessary to ensure that there is clean hydraulic oil and carefully check whether the hydraulic oil is used correctly, and then ensure the presence of substitutes. For hydraulic transmission systems, in order to complete their work better, not only clean hydraulic oil is required, but also good hydraulic components are needed. Only in this way can we ensure the smooth completion of the work.

2. Prevent air from entering hydraulic oil. In hydraulic systems, hydraulic oil is incompressible, but once mixed with air, it is compressible. In a system, the mixing of air can affect certain aspects of the system. For example, when oil is mixed with air, one situation or another may occur. When it is at low pressure, these gases will eventually form bubbles, leading to cavitation. Under high pressure, these bubbles will burst and produce noise in the system. Simultaneously emitting a large amount of thermal energy, in severe cases, it can damage hydraulic components.

3. Prevent hydraulic oil temperature from being too high. For hydraulic systems, there is a fixed range of operating temperatures between 30 ℃ and 80 ℃. During use, the oil temperature should be maintained within the range. In addition, after a certain period of time, the oil can be pressurized from the filtrate and the physical performance can be tested in a timely manner to better utilize the working performance of the hydraulic system.
