NOTICE:
If you want to maintain the Tunnel Mucking Machiner, taking anti-wear and anti-corrosion measures can greatly save maintenance costs. Not only do routine maintenance, but also avoid long-term overloading, overspeeding, and overloading of the Tunnel Mucking Machine, avoid wind , sun, and rain, and avoid putting it together with corrosive substances. Check regularly to ensure the correct relationship between the parts, and maintain the correctness, safety and reliability of various cooperation and connection relationships. Strictly follow the rules for regular maintenance and inspection .
The normal working efficiency of the Tunnel Mucking Machine is relatively high, but if you find that the Tunnel Mucking Machine that you drive has suddenly slowed down, Gao Feng recommends shutting down and checking immediately. The first thing to check is the internal components: the slag loader is working normally, and the hot car is slow. Generally, the internal components of the excavator are worn over time (excavator cylinder, plunger, valve plate, nine-hole plate, Turtle back and other wear), resulting in a decrease in the power of the excavator engine and internal leakage of the hydraulic system.
1. Calibrate the throttle: the engine power of the mucking rock loader is reduced, you can do a throttle calibration.
2. Hydraulic oil: The hydraulic oil of the mucking machine has not been changed for a long time.
3. Weather reasons: It may be that the engine oil of the slag raking machine has solidified due to weather, so it must be warmed up before work.
4. If the mucking machine has not been used for a long time at this time, the cause of the slow action of the mucking machine may be caused by: short circuit of the mucking machine circuit, abnormal pilot pressure, control valve -piston stuck, The distributor merges and so on.
5. Sensor: The Rock Mucking Loader speed sensor is broken or the sensor is faulty.
