Precautions for Maintaining the Hydraulic System of Rotary Drilling Rigs

Precautions for Maintaining the Hydraulic System of Rotary Drilling Rigs

Surveys show that 70% of damage to equipment hydraulic components is caused by hydraulic oil contamination. Therefore, regularly replacing the hydraulic oil and hydraulic oil filter elements is a necessary means of ensuring the safe operation of the equipment's hydraulic system.

　　The roles hydraulic oil plays during the operation of a rotary drilling rig mainly include: transmission, lubrication, cooling, rust prevention, and cleaning. The functions of hydraulic oil determine that, as working time increases, it will age internally and accumulate impurities; therefore, we need to regularly replace the hydraulic oil and hydraulic oil filter elements of the rotary drilling rig.

　　Replacing hydraulic oil is like receiving a blood transfusion at a proper hospital after suffering a serious injury. First, we likewise need to find a professional maintenance technician to perform the operation. Second, when replacing the hydraulic oil, we also need to clean the environment around the hydraulic oil tank to prevent external dust from entering the hydraulic system.

　　For the rotary drilling rigs produced by Yutong Group • Zhengzhou Yutong Heavy Equipment Co., Ltd., the equipment operation and maintenance manual has clearly listed the recommended brands and models of various oils, and the use of oils outside the recommended range is prohibited.

　　Hydraulic oils of different brands must not be mixed, because different additives may react chemically and form sediment. When changing to a different brand of hydraulic oil, the hydraulic oil tank and lines should be thoroughly cleaned.

　　The viscosity of the hydraulic oil should be selected according to the ambient temperature, and hydraulic oil with good viscosity-temperature characteristics should be chosen whenever possible.

　　The hydraulic oil return filter element is an important component for keeping the hydraulic system clean. If it is not replaced regularly, it will cause early wear of hydraulic components and reduce the service life of the equipment.

　　After replacing the old hydraulic oil filter element, carefully check whether there are large metal particles on the filter paper. If there are, please stop using the equipment and promptly contact Yutong Heavy Equipment after-sales service personnel by phone.
