The filtration system of bulldozers and multi-functional tractors is crucial for their normal operation and engine protection. It mainly includes air filtration, fuel filtration, and engine oil filtration, etc. The following is a detailed introduction:
Air filtration
Function: The air filter is used to filter the air entering the engine, preventing dust, sand and other impurities from entering the cylinder, avoiding wear on components such as the piston and cylinder wall caused by these impurities, and at the same time ensuring that the air entering the engine is clean, allowing the fuel to burn fully and improving the performance and efficiency of the engine.
Filtration method: Usually, paper filter elements or oil bath filter elements are adopted. Paper filter elements have the advantages of high filtration efficiency, low cost and easy replacement, and can effectively filter out tiny particles in the air. The oil bath filter element achieves the purpose of filtration by allowing air to pass through an oil pool, causing impurities to adhere to the oil surface. It has a better filtration effect in some harsh environments.
Maintenance points: Regularly inspect the filter element of the air filter. Depending on the dust level of the usage environment, it is generally cleaned or replaced every 50 to 100 hours of operation. When working in an environment with a lot of dust, more frequent inspection and maintenance may be required.
Fuel filtration
Function: The function of the fuel filter is to filter out harmful substances such as impurities, water and gum in the fuel, prevent them from entering the fuel system, avoid problems such as clogged fuel injectors and worn fuel pumps, ensure the normal operation of the fuel system, and enable the engine to run stably.
Filtration method: Generally, multiple layers of filter paper or metal mesh and other filtration materials are used to separate impurities from the fuel through physical interception. Some fuel filters also have a drainage function, which can effectively remove water from the fuel. Because water can cause the fuel to deteriorate, affect the combustion effect, and even damage the engine.
Maintenance points: Replace the fuel filter regularly based on the quality of the fuel and the frequency of use of the tractor. Generally speaking, the fuel filter needs to be replaced every 200 to 300 hours of operation or at certain intervals of operation mileage. At the same time, it is necessary to pay attention to choosing a reliable fuel filter to ensure the filtration effect.
Engine oil filtration
Function: The oil filter is used to filter out impurities, metal shavings and carbon deposits in the engine oil, maintaining its cleanliness. It enables the oil to circulate well within the engine, playing roles such as lubrication, cooling, sealing and rust prevention, thereby extending the service life of various engine components.
Filtration methods: There are two types of oil filters, namely full-flow type and split type. The full-flow filter is connected in series between the oil pump and the main oil passage and can filter out most of the impurities in the engine oil. The split-type filter is connected in parallel with the main oil passage and only filters a portion of the engine oil, but it can filter out finer impurities. Modern bulldozers and multi-functional tractors usually adopt both of these filtration methods simultaneously to enhance the filtration effect.
Maintenance points: The oil filter is usually replaced simultaneously with the engine oil. Each time the engine oil is changed, a new filter should be replaced. In addition, during the usage process, it is necessary to check whether the filter has any leakage. If there is any leakage, it should be replaced in time.
Through proper maintenance of the filtration system, the engine and other key components of the bulldozer and multi-functional tractor can operate in a clean working environment, reducing the probability of faults, enhancing the reliability and service life of the equipment, and lowering maintenance costs.
