Why Is The Hydraulic Oil Filter Element of A Second-hand Rotary Drilling Rig Considered A "key Component Among Vulnerable Parts"?

Among the numerous components of second-hand rotary drilling RIGS, the hydraulic oil filter element may seem insignificant, but it is the "invisible guardian" that ensures the normal operation of the equipment. Although it is a vulnerable part, it directly affects the lifespan and performance of the hydraulic system. For second-hand equipment, it is even more crucial for maintaining efficient operation.

1.The core function of the hydraulic oil filter element

The hydraulic oil filter element can filter impurities, metal debris and gum in the oil, preventing contaminants from entering precision components such as hydraulic pumps and cylinders. Once the filtration fails, impurities will accelerate component wear and cause system failure.

2. Second-hand equipment relies more on the performance of filter elements

The hydraulic system of second-hand rotary drilling RIGS may show signs of aging, and the risk of oil contamination is higher. High-quality filter elements can make up for the aging defects of equipment and reduce sudden malfunctions caused by impurities.

3. Two major reasons for the vulnerability of filter elements

One is that after long-term use, the filter material gets clogged and the filtration efficiency decreases. Second, inferior filter elements have poor impact resistance and are prone to damage under the impact of high-pressure oil. Both of these situations will cause the filter element to lose its protective function.

4. Ignoring the chain hazards of filter element replacement

The failure of the filter element will accelerate the contamination of the hydraulic oil, which in turn can cause problems such as valve group jamming and cylinder oil leakage. The cost of repairing these malfunctions is much higher than the expense of regularly replacing the filter elements.

5. Key points to avoid pitfalls when purchasing second-hand filter elements

Give priority to choosing original or compatible brand filter elements and avoid using inferior counterfeit parts. At the same time, check whether the sealing rubber ring of the filter element is intact to prevent bypass leakage after installation.

6. The correct time to replace the filter element

In addition to regular replacement as per the user manual, when the equipment shows sluggish operation or abnormal noise, the condition of the filter element should be checked in a timely manner. When replacing, the old oil should be drained simultaneously to avoid the residue of contaminants.

Although the hydraulic oil filter element is small, it serves as a "health barrier" for the hydraulic system of second-hand rotary drilling RIGS. Paying attention to its selection and replacement can effectively reduce the failure rate of equipment, extend its service life, and enable second-hand equipment to play a greater role.
