Selection of Construction Machinery Filter Element [Longrui Parts Mall]

Friends who own excavators know that the filter element is an important component to ensure the normal operation of the equipment, but also a barrier to ensure the health of the equipment. The air filter element filters the dust and impurities in the air to keep the air entering the engine cylinder clean; the fuel filter element filters the impurities in the fuel to prevent them from entering the fuel system and causing wear or failure of the fuel pump and fuel injection system; the engine oil filter element filters the impurities in the engine oil to ensure that the lubrication system of the engine is in a clean state; The hydraulic oil filter element filters the impurities in the hydraulic oil and plays a core role in protecting the whole hydraulic system. Therefore, the correct selection of the filter element is very important for the use and maintenance of the excavator. Improper selection of the filter element will not only cause early wear and tear of the relevant parts of the equipment, resulting in poor operation of the equipment, but also cause damage to the key parts, which will bring unnecessary huge losses to users.

With the rapid increase in the number of excavators, the current market is flooded with a variety of low-cost filter elements produced by manufacturers who do not have the relevant manufacturing technology and conditions. If you choose these non-pure filter elements only because of their low price, it will undoubtedly bring hidden troubles to your machine.Longrui Accessories MallHere are two examples of failures caused by the filter element.

 Case 1 Due to the use of a non-pure engine oil filter element, the engine oil supply is not smooth, the lubrication is poor, and the crankshaft is stuck, which eventually leads to the crankshaft fracture.

In case 2, a non-pure filter element could not withstand the pressure of hydraulic oil and ruptured, and a large amount of residue was sucked into the hydraulic system, resulting in damage to the hydraulic pump and paralysis of the whole vehicle.

In these two cases, the improper selection of filter elements caused serious damage to the engine and hydraulic system respectively.

Selecting the pure filter element of the manufacturer is undoubtedly an important means to avoid the above problems. Here, Xiaobian takes the hydraulic oil filter element as an example to compare the Komatsu pure filter element with a common non-pure filter element on the market.

1. Cut open the skin for comparison.

2. Disassemble the filter paper for comparison

The filtration area of Komatsu pure product is significantly larger than that of a non-pure product.

3. Comparison of filter paper after use

If the pressure resistance of the filter element is poor, it will not be able to capture tiny dust and impurity particles, which will easily lead to impurities such as metal fragments and filter material fragments flowing back to the oil tank, affecting the service life of the main pump and main valve.
