As summer arrives, high - temperature and dry weather sweeps across many areas, leading to a surge in demands for farmland irrigation and domestic water supply. The UNIQUE water well drilling rig, with its efficient and stable performance, has become a core equipment to solve water - use problems. However, under high - frequency use, if the equipment maintenance is not in place, it is very easy to cause hydraulic system failures and seriously shorten the mechanical service life. Among them, the regular cleaning of fuel tanks and filters is a key link to ensure the continuous and efficient operation of the drilling rig. The following will give you a detailed explanation of the operation points.

Return Oil Filter: Clean Monthly to Block Return Oil Impurities

Take the UNIQUE crawler - type drilling rig as an example. Its return oil filter is accurately installed above the fuel tank and directly connected to the return oil pipe. Its main function is to filter impurities such as metal debris and seal wear particles in the return oil of the hydraulic system. During summer drilling operations, the circulation speed of hydraulic oil accelerates, and the deposition speed of impurities also increases accordingly. Therefore, it is necessary to insist on cleaning it once a month.

The cleaning operation steps are simple and easy to follow: directly unscrew the filter element, rinse it repeatedly with clean diesel until there are no visible impurities on the surface of the filter element. After flushing, it is necessary to check whether the filter element is damaged, deformed or the filter holes are blocked. If there are the above problems, the new filter element should be replaced immediately. It is recommended to use the UNIQUE original supporting filter element, which has a filtration accuracy of 5μm. It can perfectly adapt to the hydraulic system of the equipment and effectively avoid secondary pollution caused by inferior filter elements.

Suction Oil Filter: Self - locking Design to Ensure Clean Suction Oil

The suction oil filter of some UNIQUE drilling rigs is installed under the fuel tank and closely connected to the oil suction port of the oil pump. It is responsible for pre - treatment filtration before hydraulic oil enters the oil pump. The filter has a patented self - locking device, which will automatically close the oil port when the filter element is removed, completely eliminating the problem of hydraulic oil leakage and greatly improving the maintenance safety.

The cleaning frequency is also once a month, and the operation process is the same as that of the return oil filter: after unscrewing the filter element, rinse it with clean diesel, focusing on cleaning the small impurities hidden in the folds of the filter element. If the filter screen of the filter element is found to be damaged or the sealing rubber ring is aged, it should be replaced in time. It is worth noting that the suction oil filter directly affects the service life of the oil pump. If it is not cleaned for a long time, impurities entering the oil pump will cause rapid wear of internal parts, and the maintenance cost will increase by more than 30%.

Core Value of Regular Maintenance

Adhering to the regular cleaning of fuel tanks and filters can effectively reduce the failure probability of the hydraulic system of the UNIQUE drilling rig by more than 60% and prolong the overall service life of the equipment by 3 - 5 years. During summer maintenance, it is recommended to check the oil level and oil quality of the hydraulic oil in the fuel tank at the same time. If the oil is found to be turbid, emulsified or discolored, it is necessary to replace the new oil in time and thoroughly clean the inside of the fuel tank.
