How often should the excavator hydraulic oil filter be replaced

The excavator hydraulic filter element mainly filters impurities in the hydraulic system. After the filter element has been used for a period of time, the filter element will gradually clog and need to be replaced and maintained. So can the excavator hydraulic oil filter be reused? How often should it be replaced?

Usually most excavator hydraulic filter elements cannot be reused, and only a small part can be used after cleaning, such as oil absorption filter elements, because oil absorption filter elements belong to coarse filtration and are made of stainless steel woven mesh, sintered mesh, copper mesh and other materials, as shown in these cleanings. After that, you can continue to use it. It should be noted that the filter element must be replaced when it is damaged.

1. The specific replacement time of the filter element is not clear. It should be judged according to different functions and usage environments. Universal filters will be equipped with a sensor. When the hydraulic filter element is blocked or needs to be replaced, the sensor will alarm, and then the filter element needs to be replaced;

2. Some hydraulic filter elements do not have sensors. At this time, by observing the pressure gauge, when the filter element is blocked, it will affect the pressure of the entire hydraulic system. Therefore, when the pressure in the hydraulic system becomes abnormal, the filter can be opened to replace the filter element inside;

3. According to experience, you can also see how often the commonly used filter element is replaced, record the time, and replace the filter element when the time is about the same;

Excavator hydraulic filter element is mainly used to filter out solid particles and colloidal substances in the working medium, which can effectively control the pollution degree of the working medium and protect specific components in the hydraulic system. It is installed upstream of the protected component in the medium pressure pipeline, allowing the component to function properly. Whether in the hydraulic system of steel mills, power plants, chemical plants or construction machinery, hydraulic filter elements always play an important role. Therefore, when purchasing hydraulic filter elements, it is recommended not to be cheap, but to choose high-quality products to protect the service life of the equipment. As a reminder, when replacing the hydraulic oil filter, check the bottom of the filter for metal particles or debris. If there are copper or iron pieces, the hydraulic pump, hydraulic motor or valve may be damaged or will be damaged. If there is rubber, the hydraulic cylinder seal is damaged. I’ve been talking to you about the filter lately.

For consumable components, the replacement cycle is a problem that many manufacturers are very concerned about, so how often should the hydraulic filter element be replaced? How to judge the excavator hydraulic filter needs to be replaced? Under normal circumstances, the hydraulic oil filter is usually replaced every three months. Of course, this also depends on the wear of the hydraulic filter element. Some mechanical equipment is expensive, so the replacement time will be shortened. At the same time, we also need to check whether the oil filter is clean every day. If the oil filter of the hydraulic filter element is not clean, it needs to be checked and replaced in time. The filter grade of the excavator filter element has a great influence on the healthy operation of the equipment. The replacement of the filter element must be carried out in conjunction with the operation of the equipment. If there is a problem, it must be checked and replaced, so as to avoid equipment failure and greater losses.
