Maintenance Period Study About The Track Excavator Hydraulic System

China has entered a rapid development of infrastructure construction phase of infrastructure construction in the use of the high-performance engineering construction machinery more and more, often using such mechanical hydraulic drive, how to make good use of the machinery, how to manage good mechanical equipment hydraulic system, the machinery to play a greater economic benefits, the construction sector is needed to solve the problems. The Construction Machinery hydraulic system, the current is usually taken to repair the bad management methods. Clearly, the current mode of management of mechanical machinery should not play the effectiveness and shorten the useful life of machinery. In view of the actual management of construction machinery, construction sector in urgent need of an advanced model of good management and good use of the advanced level of construction machinery. Reliability model for the management of the Centre is an advanced management mode. But until now, construction machinery reliability management study did not really carry out, construction machinery hydraulic system reliability studies more weak.This paper introduces the reliability of the hydraulic study used normal distribution, exponential distribution and Weibull distribution model and the basic characteristics of the repair and maintenance of indicators, as well as the calculation of the effective reliability and effective maintenance of the relationship between ; hydraulic crawler excavator of the reliability of the system on the basis of summarizing the collected data, in the absence of data, both at home and abroad have been using the basic components of the hydraulic failure rate, and in accordance with the hydraulic system Reliability connection reliability of the hydraulic system failure probability and the reliability of forecasting methods; According to Komatsu PC200-6 hydraulic system reliability connection, the establishment of its hydraulic system reliability model, and through depiction drew a method of hydraulic system failure probability curve (F (t)～t); use of Normality The probability distribution of paper test and parameter estimation set its failure normal probability distribution can be described the establishment of a crawler excavator maintenance cycle and the repair cycle model, and calculated the Komatsu PC200-6 crawler excavator hydraulic system Periodic maintenance and overhaul cycle. In the maintenance of the existing research methods on the basis of proposed improvements. Papers by the content of the study, the four-point conclusion, described in the construction of the reliability of the hydraulic system in the mechanical application of some knowledge.
