How to use the observation method to diagnose the hydraulic system failure?

The failure rate of the hydraulic equipment of the electric pallet stacker is generally high due to design, manufacturing, transportation, installation, commissioning, and other reasons at the initial stage. With the extension of operation time and continuous troubleshooting, the failure rate will gradually decrease. In the late stage of equipment use, failures gradually increase due to wear, corrosion, aging, fatigue, etc. during long-term use. The pallet stacker manufacturer told everyone that only in the middle of use, equipment failures tend to be random and stable, which is the effective working life of the equipment.

However, if improper use or potential failures are not diagnosed and eliminated in a timely manner, even during the effective life of the electric pallet stacker, sudden and serious failures cannot be ruled out. Therefore, careful study and summary of equipment faults and diagnostic techniques are the prerequisite for correct and timely troubleshooting of various faults. The most basic methods of fault diagnosis commonly used include observation method, logical analysis method, and instrument detection method. Observation method and logical analysis method are qualitative analysis methods. Today, the pallet stacker manufacturer will tell you how to use the observation method to diagnose the hydraulic system failure of the electric pallet stacker.

The pallet stacker manufacturer told everyone that observation and diagnosis is actually an initial intuitive diagnostic method that combines the observation, rattle, auditory, and touch sensations of human eyes, nose, ears, and hands with daily experience to analyze whether there are faults, fault locations, and causes in hydraulic equipment. Generally, any fault will be accompanied by various abnormal symptoms before it evolves into a major fault. Several common symptoms are as follows: First, abnormal vibration and noise occur on electric pallet stacker, especially at hydraulic components such as hydraulic pumps, hydraulic motors, and hydraulic valves. Secondly, there is a decrease in the working speed, pressure reduction, and weakness of hydraulic actuators (hydraulic motors, hydraulic cylinders); Third, there are phenomena such as excessive temperature rise of the working oil and a smell of burnt smoke. Fourth, pipeline damage and looseness occur. Fifth, there are phenomena such as deterioration of pressure oil and decrease of oil tank level in electric pallet stacker.

The pallet stacker manufacturer told everyone that as long as these phenomena are frequently inspected and observed, it is not difficult to detect them. Taking these on-site phenomena as first-hand information, based on experience, relevant charts, and data, it is possible to quickly determine whether there is a fault, its nature, location, and specific cause of the fault, and then proceed to take measures to eliminate the fault of the electric pallet stacker or to prevent the occurrence of major faults.
