Question 2 A construction company reported that one of their excavators has slow and weak arm movements. The hydraulic system shows signs of overheating, and the operator notices hydraulic fluid contamination. Initial inspections suggest possible pump wear, valve blockages, or fluid degradation. a) Prepare a list of hydraulic components that could contribute to the excavator's slow arm movement and explain their functions in the hydraulic circuit.. [5 Marks] b) Analyse how a worn-out hydraulic pump could lead to reduced system pressure and slower actuator movement. Include the relationship between pump efficiency and system performance.. [5 Marks] c) The hydraulic fluid is found to be contaminated. Analyse how contamination affects valve operation and cylinder performance, and propose potential sources of contamination in this system. [5 Marks] d) The system is overheating. Compare normal operating temperature ranges with the observed overheating condition and explain how excessive heat could damage hydraulic seals and hoses. [5 Marks] e) The company is debating whether to switch to a fully electric excavator. Evaluate the pros and cons of hydraulic systems compared to electric systems in heavy machinery, considering power density, reliability, and environmental factors. [5 Marks]
