There are frequent rainstorms in summer,and the machine will inevitably be wading in water.Regular maintenance of the HDD machine can reduce the failure and maintenance cost of the machine, and improve the work efficiency and economic benefits.
Check the integrity of the machine: Observe several laps around the machine to see if there are missing parts; Whether there is foreign body blockage; Whether standing water. In particular, foreign body blockage of rotating parts, such as engine compartment fan, belt and radiator should not be blocked by foreign body, otherwise the engine will produce safety and component damage hazards.
Solution: Fill up lost parts, clean up blocked foreign bodies, remove water, clean up air drying (such as engine air filter and module cabin, engine compartment and pump cabin); If the machine needs cleaning, please be careful not to use high-pressure water gun to flush electrical parts such as plugs and modules, engine compartment and each fuel tank filling port.
Check the engine:Check whether the lubricating oil and diesel oil of the whole machine are normal, check whether the liquid level is normal, water and mud entering will make the liquid level rise, must check the engine system, engine oil, antifreeze, and diesel oil;
Solution:Consult the engine manufacturer or technician If there is any abnormal.
Check the hydraulic system:
Check the hydraulic system
Hydraulic oil system, hydraulic oil tank and diesel tank filler caps are equipped with ventilation devices. In normal use, no impurities will enter, but if they are soaked for too long, water and sediment will enter.
Solution: Drain the hydraulic oil, clean the hydraulic oil tank, replace the hydraulic oil and the filter element in the hydraulic oil tank;
Other lubricating oils: mud pump crankcase, power head gear box, crawler reducer oil;
Solution:If water and sediment enter, the lubricating oil must be drained, and the box must be cleaned before adding new lubricating oil;
Check the electrical system:
Gookma horizontal drilling rig harnesses use high-quality flame-retardant wires, with wear-resistant nylon protection layer, equipped with high-quality German connectors, and all electrical components have IP67 protection level. However, after being washed and soaked by mud and water, especially for the machines that have worked for many years, the components and parts are aging. It is recommended to check the electrical components (whether they are loose, soaked and rusted), such as relay, solenoid valve coil wiring plug, etc.
Please focus on checking whether the C248 computer controller is wading. In case of wading, please remove the controller from the machine and dry it in a dry and ventilated place to avoid short circuit or damage to electronic components caused by corrosive liquid inside. If the controller contact is corroded, please replace it to avoid chain failure and damage to the machine electrical system.
Solution: Check whether the electrical parts are loose and rusty. If there is no problem, do not start the engine if the machine is powered on. Check whether the fuse is burned and whether the engine display screen has alarm information if there is power on. If a fuse is burned, check whether there is a short circuit or other faults on the line where the fuse is located. You can contact Gookma after-sales service engineers. After completing the above inspection and troubleshooting, ensure that there is no problem before you can start the engine, and then check the hydraulic function.
