What is the "four filters" of cranes?

The so-called filter, as the name suggests, its main responsibility is to filter the oil, fuel and air that enter the equipment from the outside to ensure that impurities do not cause "internal injury" to the equipment.

The "four filters" are separatetruck craneAmong the different systems, the oil filter is in the lubrication system, the fuel filter is in the fuel system, the oil return filter is in the hydraulic system, and the air filter is in the air system. Filters in different systems have the same responsibilities. Today, Brother Chong will introduce to you the "four filters" that we are familiar with and unfamiliar with.

1.Oil filter

The oil filter connects the oil pump and the major components in the engine, and its main responsibility is to guard the gate, filter the oil in the oil pump and transport it to the internal parts of the engine, so that the engine can operate better. The main function of engine oil is lubrication, and the oil entering the parts will form an oil film on the surface of the parts, which has a lubricating effect. Without an oil filter, the oil and airborne impurities will enter the engine, and the oil film will no longer be a smooth oil film, but an oil film covered with dust and impurities, which will cause chronic and fatal damage to the parts.

2.Fuel filter

Construction machinery and equipment such as truck cranes mostly use diesel as fuel, so fuel filters are subdivided into gasoline filters, diesel filters and natural gas filters. The fuel filter is in the fuel gas system and its main responsibility is to filter the fuel entering the engine. The fuel filter is connected in series to the pipeline between the fuel pump and the throttle body oil inlet, and its function is to remove solid debris such as iron oxide and dust contained in the fuel, prevent fuel system clogging (especially fuel injectors), reduce mechanical wear, ensure stable engine operation, and improve reliability.

3.Air filter

Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields to provide clean air for mechanical equipment to prevent these mechanical equipment from inhaling air with impurity particles during work, increasing the probability of wear and damage.

4.Oil return filter

This is an important filter that distinguishes truck cranes from other equipment. The oil return filter is located in the hydraulic system of the truck crane and is responsible for filtering the hydraulic oil entering the hydraulic components. The truck crane has a very large and important hydraulic part - the boom, and the use of hydraulic oil is also very large, therefore, the oil return filter element we see is also a very large piece, its main responsibility is to filter the hydraulic oil entering the hydraulic components, to avoid impurities entering the hydraulic oil, causing damage to the hydraulic components.
