dc.description.abstractOverheating is a critical problem encountered with an electro hydraulically operated machine working in underground mines. Aggrandizement in the temperature of the hydraulic fluids is caused due to deficiencies in the components. Thermal instability of hydraulic power systems causes temperature transients, which not only mitigates machine productivity but is also harmful. Especially considering the system inefficiency, the hydraulically driven machine has an inbuilt cooling arrangement. When the energy loss caused by faulty elements exceeds the system cooling capacity, hydrostatic transmission is overheated. Mathematical models, experimental studies, and analytical approaches evaluate the substantive reasons for heating and determine heat energy generation due to inefficient parts of the hydraulic system of the load haul dumper. The mathematical model is used to calculate heat energy addition, emulating power loss in hydraulic components and equivalence. Efficiency block diagram of entire hydraulic system has been created. Hydraulic components get worn out in due course of continuous operation of the machine. While calculating the series function, the overall efficiency up to 60% of all the components in the system will not accumulate the heat in the system. The Weibull distribution is used to analyse system reliability, and it is discovered that if the system inefficiency exceeds 40%, failure rate due to overheating increases. Excess heat energy causes fluid degradation, deterioration of rubber parts and seals, acceleration of wear, and tear of relative and mating parts and has an impact on the overall operation of the machine. Actuators' performance becomes erratic and sluggish.
