What are the maintenance methods for the hydraulic system of Komatsu excavators?

The hydraulic system plays a vital role in excavators. Good hydraulic oil enables the hydraulic system to ensure the stability of mechanical operation and protect the excavator. The following excavator and forklift driver recruitment job search website specializes in the driver market and analyzes how to care for our hydraulic system:

1. Choice is very important

Be sure to choose the right one High-quality hydraulic oil can play a role in transmitting pressure, lubrication, cooling, and sealing in the hydraulic system. Improper selection of hydraulic oil is the main cause of early failure and reduced durability of the hydraulic system. The normal method is to identify the color of the hydraulic oil. If you find dark brown, milky white or obvious odor hydraulic oil, it is deteriorated oil and cannot be used in machinery.

2. Block all unnecessary impurities

Clean hydraulic oil is the life of the hydraulic system. There are many precision coupling parts in the hydraulic system, some have small damping holes, some have gaps, etc. If solid impurities invade, it will cause strain on precision parts, hairpins, blockage of oil passages, etc., endangering the safe operation of the hydraulic system. Therefore, we can start from the following aspects:

1. The hydraulic oil should be filtered and refilled before refueling to ensure its cleanliness.

2. When performing maintenance on the hydraulic system, the refueling cap, filter cover, detection hole, hydraulic oil pipe and other parts should be disassembled to prevent unnecessary dust from being stuck on the oil pipe when it is exposed.

3. Clean the hydraulic components and hydraulic hoses, and blow them dry with high-pressure air before assembling them. When replacing the hydraulic oil, the filter should be cleaned together to ensure that there is no impurity or dirt in the filter housing.

4. Use the same brand of hydraulic oil, and the oil temperature should be controlled between 45 and 80°C. When replacing hydraulic oil, the hydraulic system should be repeatedly cleaned first, and then new oil should be filled in after cleaning is completed.

3. Regular maintenance

Check the filter regularly. Due to long-term use, many metal impurities will adhere to the filter and adhere to the oil pump or cylinder. Therefore, the filter should be cleaned in time and the oil should be replaced in time. When the hydraulic system fails, relevant maintenance personnel should be contacted in time for maintenance to reduce unnecessary losses caused by the failure.
