• Frequency of hydraulic oil replacement

The length of time and use environment of hydraulic oil in construction machinery will affect its performance. In general, the frequency of hydraulic oil replacement of construction machinery should be considered according to the following factors:

1, working time and frequency: Long time, high frequency of work will lead to faster oxidation and wear of hydraulic oil, so it needs to be replaced more frequently.

2, working environment: harsh working environment, such as high temperature, heavy load, dust, etc., will accelerate the aging of hydraulic oil, need to pay more attention to the replacement frequency.

3, hydraulic system design: the hydraulic system design of some construction machinery is more advanced, which can extend the service life of hydraulic oil, so the replacement frequency can be relatively low.

• Why scientific replacement of hydraulic oil?

Scientific and reasonable hydraulic oil replacement helps to maintain the good condition of the hydraulic system and extend the service life of mechanical equipment. Specific benefits include:

1, keep the hydraulic system clean: with the increase of use time, the hydraulic oil may accumulate impurities and pollutants, regular replacement can effectively clean the system.

2, improve the efficiency of the hydraulic system: fresh hydraulic oil has better lubrication performance and stability, can improve the efficiency of the hydraulic system.

3, reduce mechanical failure: Regular replacement of hydraulic oil can reduce the risk of hydraulic system failure, to avoid parts damage caused by aging hydraulic oil.

4, reduce maintenance costs: Scientific replacement of hydraulic oil helps to reduce mechanical failure, thereby reducing the cost of maintenance and replacement parts.

• Steps to replace hydraulic oil

Scientific replacement of hydraulic oil is not only a simple oil replacement, but also need to pay attention to the following steps:

1, oil drainage and cleaning system: before replacing the hydraulic oil, carry out the system drainage, and reduce residual pollution by cleaning the inside of the system.

2, choose the appropriate hydraulic oil: according to the requirements of construction machinery, choose the appropriate viscosity and performance of the hydraulic oil.

3. Replace the oil filter: replace the hydraulic oil filter at the same time to ensure that the new oil is not contaminated when entering the system.

4, check the status of the hydraulic system: while replacing the hydraulic oil, check the various parts of the hydraulic system to ensure that there is no abnormal situation.

Through the above steps, we can ensure the comprehensiveness and scientificity of hydraulic oil replacement, and improve the operation efficiency and life of construction machinery.

In summary, the replacement frequency of construction machinery hydraulic oil should be scientifically and reasonably determined according to the actual situation. Scientific replacement of hydraulic oil helps to maintain the normal operation of the hydraulic system, extend the service life of mechanical equipment, and is a key part of ensuring the long-term stable operation of equipment.
