Hydraulic equipment debugging failure rate is high, is characterized by design, manufacturing, installation and other quality problems cross. The failure of the hydraulic system is sometimes caused by the failure of a component in the system, so first of all, find out the fault component, and then follow the steps to check to find the fault component in the hydraulic system.

Step 1: The operation of the hydraulic transmission equipment is abnormal, such as no movement, unstable movement, incorrect movement direction, unsatisfactory movement speed, chaotic movement sequence, unstable output force, serious leakage, crawling, etc. No matter what the reason, can be summed up in three major problems: flow, pressure, direction.

Step 2: Check the hydraulic circuit diagram, check each hydraulic component, confirm its performance and function, and preliminarily evaluate its quality.

Step 3: List the components related to the failure and analyze them one by one. In this step, one is to make full use of judgment, and the other is to pay attention not to miss components that have a significant impact on the fault.

Step 4: Arrange the components listed in the list based on previous experience and the ease of component inspection. If necessary, list the key components that need to be checked and the key inspection parts of the components, and arrange the measuring instruments.

Step 5: Conduct a preliminary inspection of the key inspection elements listed in the list. The initial inspection determines the following issues: the proper use and assembly of the parts. Whether the measuring devices, instruments and test methods of the components are suitable; Whether the external signal of the component is appropriate, whether it reacts to the external signal, etc. Pay special attention to the warning signs of some components, such as excessive temperature and sighing, vibration and leakage.

Step 6: If the silkworm is not qualified in the initial test, check repeatedly with the instrument.

Step 7: Identify faulty components and repair or replace those that fail.

Step 8: Before restarting the host, be sure to carefully consider the causes and consequences of this failure. If the fault is caused by pollution or high oil temperature, it should be expected that other components may also fail, and corresponding measures should be taken against the hidden dangers. For example, if a hydraulic pump fails due to contamination, the system needs to be cleaned and filtered before a new pump can be replaced.
