What are the main components of a tractor's lubrication system? The engine lubrication system is the core part of the tractor's lubrication system, mainly consisting of the oil pump, oil filter, oil cooler, oil tank, and lubricating oil lines. The oil pump is responsible for drawing oil from the oil tank and delivering it to the lubrication points, ensuring that the friction surfaces of all engine components receive adequate lubrication; the oil filter removes impurities and contaminants from the oil to maintain its cleanliness; the oil cooler functions to lower the oil temperature, preventing overheating that could impair lubrication effectiveness; the oil tank and lubricating oil lines serve as the storage and delivery channels for the oil. The hydraulic system is another important part of the tractor's lubrication system, mainly composed of the hydraulic pump, hydraulic oil tank, hydraulic filter, hydraulic valves, and hydraulic oil lines. The hydraulic pump is responsible for drawing hydraulic oil from the tank and delivering it to the hydraulic system, providing hydraulic power; the hydraulic filter functions to filter impurities and contaminants from the hydraulic oil, ensuring the normal operation of the hydraulic system; the hydraulic valves control the flow direction and pressure of the hydraulic oil, enabling the normal operation of various hydraulic functions on the tractor; the hydraulic oil lines are the delivery channels for the hydraulic oil. The steering system is another key component of the tractor's lubrication system, mainly consisting of the steering pump, steering oil tank, steering valves, and steering oil lines. The steering pump is responsible for drawing steering oil from the tank and delivering it to the steering system, providing steering power; the steering valves control the flow direction and pressure of the steering oil, enabling the tractor's steering operations; the steering oil lines are the delivery channels for the steering oil.
