Some ways of diagnosing mine equipment faults

Due to the different functions, structures and working states of mining machinery and equipment, the forms of faults are not exactly the same. The frequent faults mainly include: sudden reduction of mechanical performance parameters, significant increase of residues due to wear, violent fluctuation of voltage and current, etc. [3]. There are various ways of mechanical failure, which fully reflects the complex causes of failure. In addition, the probability of failure of coal mine equipment is not invariable, but changes with the extension of service time. However, we must take corresponding measures to deal with the fault in time. Nanchang Kerui Mining Machinery Co., Ltd


using mine hoist detection technology


Generally speaking, ensuring the safe operation of the mine hoist is of great significance to ensure the normal operation of the whole coal mine, which is closely related to the safety of the working environment of coal mine staff. In the diagnosis, the industrial and mining parameters should be measured first, and the relevant data obtained should be processed and studied. Generally speaking, soft fault is an inducement leading to hard fault. Therefore, technicians should pay full attention to the inspection and maintenance of soft fault and be able to conduct regular pre diagnosis. In order to fully ensure the safe and stable operation of the hoist, scientific and technological workers have conducted a lot of analysis on various technologies and developed detection equipment that can diagnose the hoist [4] to ensure the smooth operation of the hoist.


using information processing technology


All kinds of information related to mining equipment collected on site cannot be directly used as the basis for judging the current situation of the equipment, because there are both relevant information and irrelevant data. Therefore, first, deal with the collected information, screen out valuable information and convert it into information that can be read by machines or people, Only in this way can we truly complete the collection of information. In this process, confidence processing technology plays an important role. Nanchang Kerui Mining Machinery Co., Ltd


monitoring by working condition parameters


Industrial and mining parameters mainly include basic parameters such as equipment temperature, normal pressure and vibration. Technicians can diagnose these parameters to find faults. Here, take temperature diagnosis as an example. Its feasibility basis is that the temperature of the faulty equipment is generally abnormal during operation. Based on this, Technicians can input the normal working temperature of each component in each equipment into the system database. If abnormal temperature is found in the process of on-line monitoring, they can judge the specific location and possible causes of the fault or about to occur according to the data indicators, After receiving the alarm, the maintenance technician can repair the fault immediately to ensure the smooth operation of the equipment.


there shall be certain guarantee for equipment investment


So far, many enterprises still use relatively original equipment. Aging mechanical equipment leads to limited technical level and can not be improved. Coal mining enterprises should increase investment in equipment funds, eliminate a number of old equipment with serious noise pollution and high power consumption, and purchase new high-tech equipment, which can not only improve the performance of equipment, but also improve work efficiency.
