Equipment management of the three rates of "completion rate, accident rate, to be repaired" of the statistical methods of the requirements are clear as follows: First, the equipment completion standards: 1, spare parts complete and intact. 2, good performance, output and accuracy to meet the requirements of energy consumption within the specified range.
2, good performance, output and accuracy to meet the requirements, energy consumption within the prescribed range. 3, safety protection devices are complete and reliable. 4, equipment environment is clean.
5, and the equipment has a direct relationship with the integrity of the records and technical information is complete and accurate.
Second, the malfunction rate statistical calculation method:
1, grass-roots units monthly statistics, reported to the Electrical and Mechanical Section, Electrical and Mechanical Section statistics summarize the mine's three rates of data, to generate statistical reports. Report format is attached.
2, the monthly charter inspection failed equipment that month for incomplete equipment.
3, planned maintenance does not have the conditions for the start of the equipment counted as intact equipment, fault maintenance does not have the conditions for the start of the equipment counted as incomplete equipment.
4, the month failed to have the conditions of the whole month out of the number of complete units = the number of complete days/month calendar days.
5, equipment completion rate = the number of units in good condition / the number of units on the register. 6, the annual completion rate for the weighted average of the monthly completion rate.
Three, to be repaired rate of statistical calculations:
1, equipment failure date and the date of the start of maintenance between the date interval for the date to be repaired, a single
equipment month to be repaired with the ratio of the monthly calendar date of the number of units to be repaired. 2, equipment to be repaired rate = the number of units to be repaired / the number of units on the register.
3, the annual equipment repair rate for the weighted average of the monthly equipment repair rate. Fourth, the accident rate statistics calculation method:
1, recognized by the Electrical and Mechanical Section, according to the mechanical and electrical accident treatment of mechanical and electrical equipment failure is calculated as an accident. 2, the accident rate = the accident affects the month's production / the month's planned production or
= the accident affects the month's system operating time / the month's planned operation of the system. 3, the annual accident rate is the weighted average of the monthly equipment repair rate.
