Maintenance is an important means to guarantee the extended service life of rotary drilling rig, and daily inspection is an important supplement. Routine inspection, that is, "three checks" system, is the machine hand, must do every day, must comply with.
what is "three checks", "plainly" is to check before work, work inspection and inspection after work.
1. check
before work. Check the engine oil, diesel oil and coolant every day before starting. And hydraulic oil or hydraulic transmission oil. Every good hand understands and must do it. Check capacity and quality, or add or replace.
is also around the machine, open the hood to see the machines, there is no missing parts, such as generators, batteries and other key parts; connecting screws have lost, loosening, for example: Engine claw bolt, drive shaft screw and hydraulic pump screw etc.. Also observe the body and the ground, there is no oil leakage, leakage of coolant phenomenon. In the wrong place, deal with it in time. In
2., check the
before starting the engine, and check the machine around to make sure that there are no obstacles to safety. Start the engine and run idle for 3-5 minutes until the engine temperature and engine oil pressure are normal.
listen to the sound of the engine and hydraulic system is normal, observe the instrument shows whether normal; when the engine temperature is normal, do a few actions, check the speed of movement is normal, can't have stuck. In normal operation, pay attention to the sound of the engine and hydraulic system, movement speed, engine exhaust color and so on, to observe the instrument display, if there is abnormal, need to stop, find the cause, remove before use. Check the
end of
3. after work, don't immediately turn off, idling the car for 3-5 minutes, until the engine temperature down, and then turn off, can effectively protect the engine exhaust gas turbocharger and engine. Park the machine in a level place with drainage facilities or prevent rainwater from soaking. Check the connecting parts (except for high temperature parts) to see if it is normal, the screws are missing or loose, and filled and tightened in time.
adhere to the "three check" system, develop habits, the machine is a great advantage, can effectively prevent the occurrence of failures, both to improve the integrity of the machine, but also to create greater economic benefits.
