1. Corruption among the cadres has become a common practice, and the accounts of the enterprises are in chaos. It seems that they have to go on the market to earn money. It's not approved. It's killing people. The workers go on strike every day, and the chairman is dismissed all his life. Now there is no one working in the factory, the quality of the procts is falling rapidly, and it's going to close down. The heavy machinery and the state are not in charge, and the people can't live
2. I don't know if it will go bankrupt. It seems that the treatment is good. I don't know if it's a reporter. Your question is so strange!

6. If the shearer can't be adjusted up or down, it must be caused by its lack of pressure or hydraulic pipe line.
7.
Mainly from several aspects:
-
inverter power? If there is no power, what fault will be reported (if there is a fault code, remove the fault according to the fault code)
-
the inverter does not have power, check the PLC control circuit, and check whether the front-end contactor of the inverter absorbs and does not
-
confirm the traction brake and release it< br />
8. China's coal mine machinery and equipment fault diagnosis technology mainly includes the following:
1. Fault diagnosis method of oil analysis
extract the oil sample in the lubrication system of coal mine machinery and equipment, use oil analysis technology such as ferrography analyzer to identify or observe the morphology of wear debris particles in the oil, and identify the changes of their chemical and physical components, Finally, the operation of mechanical equipment to make analysis and judgment
2. Fault detection method of instrial endoscope
currently, the most widely used detection technology is the fault detection method without damage to mechanical equipment, and the biggest advantage is that the mechanical equipment will not be damaged in the case of surface and internal problem inspection. The most common is to use the instrial endoscope to detect the coal mine machinery and equipment, which can preliminarily analyze the material, processing proceres and existing problems of the tested machinery and equipment, so as to check the faults that will appear
3. Fault diagnosis method of vibration analysis and detection
this technology is mainly based on the regional characteristics of vibration signal frequency and the change of characteristic value ring the operation of mechanical equipment to analyze and study the operation of mechanical equipment, so as to diagnose the fault. Using the vibration analyzer to analyze and detect the operation characteristics and changes of mechanical equipment can show it accurately, directly and timely. This technical method is simple and has practical application effect, and is widely used
4. The fault diagnosis method of infrared temperature measurement
because of the friction damage of mechanical equipment, the nodes between burnt electrical appliances and other reasons, the temperature of some equipment materials will increase, which will damage other functions of equipment materials. According to these factors, infrared thermometer is used to monitor the temperature of different parts of mechanical equipment, and make scientific diagnosis of the operation of mechanical equipment according to the change of temperature.
