Hydraulic motor is a commonly used accessory in mechanical equipment, and the normal operation of machinery cannot be separated from the operation of hydraulic motor. After 200 hours of use of excavator, the hydraulic oil is contaminated and deteriorated, and the contaminated oil is milky white and viscous. It is preliminarily judged that it is caused by a large amount of water entering the hydraulic motor. Therefore, it has been decided to clean the hydraulic system of the whole machine and replace the hydraulic oil. Today, the hydraulic motor manufacturer will explain the solution to the problem of water entering the hydraulic motor:

1. Oil water separation effect

Connect all pipeline joints and add the previously released hydraulic oil to the factory standard. Start the hydraulic motor until the oil temperature reaches 50 ℃, let the machine run for 1 hour, and observe that the oil is light yellow with a clear color.

After continuing to use for 10 hours, the oil was observed again and no signs of deterioration were found. The oil color remained clear, indicating that the oil was basically normal. Subsequently, the machine was tracked and no further deterioration was found. Thus, the problem of oil deterioration has been completely solved, and it also proves that under limited conditions, this oil water separation method is effective.

2. Hydraulic motor for oil-water separation

Considering that further cleaning may require higher costs, after research, it has been decided to use the oil water separation method to separate the water content in the system. The manufacturer of the oil water separation method hydraulic motor has compiled the following steps:

After the hydraulic motor completes one cycle action, level the excavator, fully retract the boom and bucket cylinder, and allow the hydraulic oil in the cylinder and pipeline to flow back to the oil tank to the maximum extent. After turning off the machine, release the oil in the hydraulic oil tank, cylinder, pipeline, walking motor, and accessories.

3. Preventive measures

Based on the actual situation analysis, such a large amount of water can only enter through the oil filling port of the hydraulic oil tank, which is highly likely caused by misoperation. The hydraulic oil tank cover of this machine is a simple rotary installation form without protective lock protection. In order to avoid misoperation from happening again, it has been decided to install a protective lock on the hydraulic oil tank cover.

The above article is a detailed compilation of solutions for hydraulic motor water ingress by hydraulic motor manufacturers.
