In-depth analysis and solutions for the problem of electric pallet stacker lifting vibration

I. Hydraulic system problems: in-depth analysis of core factors

1. Insufficient or contaminated hydraulic oil
As the "blood" of the hydraulic system, the quality and quantity of hydraulic oil are directly related to the operation of the system. When the hydraulic oil is insufficient, the system pressure is insufficient, and it is difficult to provide stable power output, resulting in unstable lifting action. On the other hand, if impurities, water or metal debris are mixed into the hydraulic oil, it will accelerate the wear of hydraulic components, affect the fluidity and lubricity of the oil, and then cause vibration. Therefore, regularly checking the level and quality of the hydraulic oil and replenishing clean hydraulic oil in time are key measures to prevent vibration problems.

2. Oil leakage cannot be ignored
The oil pipes, joints and seals in the hydraulic system are key components for maintaining stable oil pressure. Any leakage will cause the system pressure to drop, affecting the stability of the lifting action. The reasons for leakage are various, including aging and damage of seals, loose or improper installation of oil pipe joints, etc. Regularly checking the integrity of these parts and replacing aging or damaged parts in time can effectively prevent oil leakage.

3. Hydraulic valve failure: the "bottleneck" of fine control
As the "commander" that controls the flow direction and flow of hydraulic oil, the performance of the hydraulic valve directly affects the stability and response speed of the hydraulic system. Problems such as valve core jamming, poor sealing or improper adjustment may cause poor flow of hydraulic oil and cause jitter during lifting. Therefore, regular cleaning, inspection and debugging of hydraulic valves to ensure that they are in the best working condition is an important part of reducing jitter.

2. Solution: A comprehensive strategy from prevention to maintenance
1. Strengthen daily inspection and maintenance
Establish a strict daily inspection system, including hydraulic oil level and oil quality inspection, leakage detection of hydraulic pipelines, joints and seals, and evaluation of the working status of hydraulic valves. Timely discovery and handling of potential problems can effectively avoid the occurrence of jitter.

2. Improve the level of hydraulic oil management
Use high-quality hydraulic oil and replace it strictly according to the replacement cycle recommended by the manufacturer. At the same time, use professional hydraulic oil filtering equipment to clean the oil regularly to reduce the accumulation of pollutants.

3. Strengthen training and awareness
Provide professional training for operators to understand the basic working principles of electric pallet stackers and master the basic skills of daily maintenance and troubleshooting. At the same time, enhance safety awareness and ensure that the vehicle is fully inspected before operation to avoid shaking problems caused by improper operation.

4. Introduce intelligent monitoring system
Use modern sensing technology and Internet of Things technology to equip electric pallet stackers with intelligent monitoring systems to monitor the working status of the hydraulic system in real time, warn of potential faults, and achieve preventive maintenance.
