In the excavator's operation process, the use of genuine parts, not only can reduce the whole machine operating costs, but also extend the service life, and ultimately protect the consumer's vital interests. In order to prevent consumers from misuse of non-genuine products and cause harm, the following we will often use in the operation of equipment, three filters, bucket teeth and injectors to give an introduction to the authenticity of the authenticity of the method of identification.

　　First of all, introduce the air filter element pure genuine products and counterfeit products of the appearance of the identification method.

　　****, the outer steel wire mesh of the genuine product has even hole spacing and is brushed with white antirust paint. Counterfeit products are often just ordinary wire mesh, and the steel plate holes are sparse, sometimes broken holes.

　　Secondly, the inner wire mesh of the genuine product is combined with a very even welding surface; while most of the counterfeit products are spot welded, the overlapping wire mesh is longer, and one side of the mesh is warped. Counterfeit air filter just imitates the geometric size and appearance of the real product, but simply cannot meet the engineering standard requirements of the filter, and the filtration effect is greatly reduced.

　　Thirdly, the color of the filter paper of the genuine product is milky white, the paper quality is delicate, the upper and lower lines are neatly arranged, and there is no deformation; the color of the filter paper of the counterfeit product is sulfur or other colors, the paper quality is rough, and the upper and lower lines are subjected to the assembly conditions, the filter paper is squeezed, and the lines are bent. The inferior filter paper has too high capacity to hold ash, which will make more impurities enter the engine system and cause the engine to be overhauled in advance.

　　Fourth, the pure air filter has the manufacturer's factory number at the bottom of both the inner and outer filters, while the counterfeit ones do not.

　　Now, introduce the diesel filter, machine filter of the pure products and counterfeit products of the appearance of the identification method

　　****, the pure product has bright and neat paintwork, while the fake one has dull color and spots due to the bad material of the steel plate of the shell.

　　Secondly, the drilling holes at the bottom of the genuine product are even and the silk mouth is smooth; the drilling holes of the counterfeit product are asymmetrical and there are burrs at the silk mouth. Burrs or tiny metal impurities, if present, will directly enter the engine system, causing scratches and wear of precision parts.

　　Thirdly, the head and tail of the filter paper of the genuine product are bonded with the method of metal clip strips, while the counterfeit ones are mostly stitched with staples or threads. Most of the counterfeit filters have short-circuit filter element, impurities do not pass through the filter paper directly into the engine system, the reason is that the first and last of the filter paper is not bonded firmly, this harm is very serious.

　　Next, introduce the appearance of pure and fake bucket teeth identification methods

　　****, the pure bucket teeth casting have mark and product number; fake or no mark or mark rough.

　　Secondly, pure bucket teeth have thicker side wall, and the seat groove fits closely with the heel of the teeth; counterfeit ones have thinner wall, and the seat groove fits in the front part of the heel of the teeth with a generally too large gap.　　Thirdly, the weight of the pure bucket teeth is 6KG (220-5 for example), while the fake ones are generally about 4KG. Counterfeit bucket teeth are not strong enough, not wear-resistant and easy to break. There is error in casting of the meshing part with the root of the teeth, which may cause difficulty in installation or cause the bucket teeth to fall off when digging due to too large a gap. Moreover, the use of fake bucket teeth will increase the driver's labor intensity, affecting work efficiency.

Introduce the harm of using counterfeit injectors　　Counterfeit injectors have poor processing precision, which will cause poor atomization, oil dripping, stuck and other phenomena, resulting in black smoke from the engine. Accelerates the early wear of engine parts, resulting in large losses.

　　Through the above introduction of the authenticity of spare parts for routine maintenance needs and the hazards, I believe that consumers have a deeper understanding.
