In the intake system of an engineering vehicle engine there is a filter which consists of one or more clean air filter elements. His main function is to filter out the harmful impurities in the air that will enter the cylinder, such as dust particles, garbage, etc., which can reduce the wear of cylinders, pistons, and piston rings on the engine of the construction vehicle. What are the damages to the construction vehicle caused by the inferior filter?
The use of low-price filter paper to produce filter elements, because of its large filter paper aperture, poor uniformity, low filtration efficiency, can not effectively filter out the harmful impurities of the engine, resulting in the engine car's early wear. The use of low-quality adhesives, and the use of very little, neither oil nor strong bonding, may cause short-circuit conditions at the filter joint; or use staples to connect the joints of the filter, can not be sealed and short circuit, so that a large number of harmful impurities Enter the engine to reduce engine life.
Parts of the air filter housing are mainly spot welds, which cannot guarantee tightness and cause short circuit damage to the engine. The thin material of the oil filter center tube material is not strong enough. In the process of use, the air in the center tube is sucked, resulting in damage of the filter element and blocking of the oil circuit. As a result, the engine's lubrication effect is insufficient; or the viscosity at the mouthpiece is not reliable. In the course of use, the mouth is torn apart, which causes the oil to leak in a short time, thus causing burning of the tiles and holding the shaft.
The metal parts such as the end cap of the filter element, the center tube, and the shell are not subjected to rust-proof treatment, resulting in metal rust corrosion and impurities, and the filter becomes a pollution source. What's more, using cement instead of adhesives is more harmful. On the other hand, in the daily use of the filter, if there is a blockage or excessive dust accumulation, it will cause the engine to air intake is not smooth, and a large amount of dust enters the cylinder, it will accelerate the cylinder carbon deposition speed, so that the construction vehicle engine ignition is not Smoothness, lack of power, and resulting in increased fuel consumption of the vehicle.
Therefore, the use of inferior filters costs a lot, it is recommended that users should be careful when replacing filters. It is better to use the original parts of the construction vehicle manufacturer or the filters produced by the regular manufacturers to avoid unnecessary economic losses to the construction vehicle engine.

The main features of molybdenum rods include high melting point, good thermal conductivity, low thermal expansion performance, good high temperature oxidation resistance, and high temperature strength.
Molybdenum can increase steel`s corrosion resistance in the acid-based solutions and liquid metals, thus improve its wear resistance, hardenability, weldability, and heat resistance. As an element which easy to form carbides, molybdenum can effectively avoid oxidation during steel making process, and it can be used alone or mix with other alloy element to achieve the best performance.
