If Honggang hydraulic cutting machine hydraulic oil is used in the system for a long time, it will affect the performance and efficiency of Honggang's hydraulic cutting machine, so we need to know under what circumstances the hydraulic oil needs to be replaced? This mainly depends on the degree of oil contamination. Here are three ways to determine the oil change period:
1. Visual inspection of oil change method. It is based on the experience of maintenance personnel, based on visual inspection of some conventional oil changes-such as oil black, odor, milky white, etc., to decide whether to change the oil.
2. Regular oil change method. According to the environmental conditions, working conditions of the site where the hydraulic steel cutting machine equipment is located, and the oil change interval of the used oil products, it will be replaced when it expires. This method is very suitable for companies with more hydraulic equipment.
3. Sampling method. Sampling and testing the oil in Honggang's hydraulic cutting machine on a regular basis to determine the necessary items such as viscosity, acid value, moisture, particle size and content, and corrosion and other indicators, according to the actual measured value of the oil and the specified oil Compare the degradation standards to determine if the oil should be changed. Sampling time: The hydraulic system of general construction machinery should be carried out one week before the oil change cycle. The key equipment and test results should be filled in the equipment technical file.
