What key points should be considered in the maintenance of the power system of a fully hydraulic portable drill rig to avoid field malfunctions?
Fuel management in the power system is the core of maintenance. Before each field operation, it is necessary to check whether the fuel in the tank is sufficient, and to select the appropriate fuel type to avoid abnormal engine operation due to incompatible fuel. After the operation, if the drill rig is not to be used again in the short term, the remaining fuel in the tank should be drained to prevent fuel deterioration and blockage of the fuel circuit. Especially in high-temperature or low-temperature field environments, the deterioration rate will accelerate, requiring timely treatment.
The maintenance of batteries and circuits cannot be overlooked. The starting battery of the fully hydraulic portable drill rig adopts a detachable design, and it needs to be removed and stored separately after each use to prevent power loss due to long-term idleness. At the same time, it is necessary to check whether the dust plugs at the circuit interfaces are intact. There is a lot of dust in the wild, and dust plugs can prevent impurities from entering the interfaces, reducing the risk of short circuits. If oxidation marks are found on the interfaces, they need to be gently polished with fine sandpaper to ensure stable circuit connections.
The cleaning of engine cooling components is equally crucial. During field operations, the drill often operates in dusty or grassy environments, and the cooling vents are prone to being blocked by impurities, leading to excessively high engine temperatures. During breaks in each operation, staff members need to use a brush to clean the debris from the surface of the cooling vents, and if necessary, use compressed air to blow away the accumulated dust inside. Additionally, it is important to regularly check the rotation of the cooling fan. If the fan is found to be stuck, lubricating oil should be added promptly to ensure the cooling system operates normally.
