What are the main components of a tractor's lubrication system? The engine lubrication system is the core part of a tractor's lubrication system, mainly consisting of an oil pump, an oil filter, an oil cooler, an 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 the engine components receive sufficient lubrication; the oil filter can remove impurities and contaminants from the oil, ensuring the cleanliness of the oil; the function of the oil cooler is to reduce the temperature of the oil and prevent overheating from affecting lubrication performance; the oil tank and lubricating oil lines are the storage and delivery channels for the oil. The hydraulic system is another important part of a tractor's lubrication system, mainly consisting of a hydraulic pump, a hydraulic oil tank, a 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 function of the hydraulic filter is to filter out 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 operations of the tractor; the hydraulic oil lines are the delivery channels for the hydraulic oil. The steering system is another important component of a tractor's lubrication system, mainly consisting of a steering pump, a 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.
