Construction machinery parts are the basis for ensuring the normal operation of mechanical equipment. Due to the demand for maintenance machinery and profit-driven, a variety of imported construction machinery and auto parts have appeared on the market, but the quality is uneven. Then, let's learn about the purchase guide for construction machinery parts!

At present, the imported construction machinery parts on the market mainly include "import" and "localization. The imported products include the pure parts of the whole machine factory, the excellent parts of the professional supporting factory, and the accessory model parts produced by countries other than the whole machine factory. Localization "parts, there are regular factories to produce imported machinery accessories parts, generally marked with the company's production mark. In addition, some informal factories and even personal studio copy of imported mechanical parts, are printed with imported pure parts or professional factory packaging, counterfeit imported pure parts for sale, in fact, is inferior. Although it can be used, it is far less than the quality requirements of pure parts, especially imitations produced by informal manufacturers, which cannot meet the quality requirements of pure parts and professional factory products in terms of material, technology, and function, which affects the normal use of machinery and equipment. And maintenance, so for business and use units, the identification of imported mechanical parts is necessary.

Not only now, the construction machinery market has been chaotic so far, and the eyes of all customers have been tested. Any parts of poor quality will bring potential construction hazards. This paper introduces the identification methods of several original parts of Kaiyuan.

Imported construction machinery parts can be identified from many aspects, mainly from the packaging, internal quality, product prices and purchase channels.

1. identification from the outer packaging

When identifying the packaging of imported parts, we should also pay attention to the fact that construction machinery and original parts manufacturers have their own professional supporting factory parts suppliers. When importing parts from manufacturers, the packaging box has the factory logo of the whole machine and the logo of the supporting factory.

2. from the product quality identification

Identifying imported mechanical parts according to product quality is an important part of identifying the authenticity of original parts. Driven by profits, some dealers assemble imported pure parts into complete machines, install pure parts in the packaging of pure parts and sell them to the market. Therefore, to confirm the authenticity of imported parts, check the inherent quality of the product. The identification of product quality is mainly observed, detected and tested.

1) Check from the appearance. Look at the appearance of the product processing is fine, color is normal. If there are samples of genuine parts, a control check can be performed. The surface of the general imitation is rough, and the color of the product is not correct.

2) Check the product identification. Imported parts are printed with brand marks, part numbers, specific codes, etc. Some products are engraved with manufacturing plants and countries of production. Imitation is not leakage casting, handwriting is not clear, it is difficult to achieve the effect.

3) Measure the size of the product through special operations to confirm whether it meets the requirements. Some manufacturers provide measuring tools to customers to prevent fakes.

4) Product performance test. Since some parts do not know the authenticity in the appearance inspection, it is necessary to use a special machine to check.

5) The physical and chemical properties of the product are tested. This is generally the method used when claiming compensation from the manufacturer when there is a question about the internal quality of the product or when there is a problem in use.

3. discriminates according to product price

Even if it is the same part, the original parts, professional factory parts, domestic parts and imitations are very different. The price of the original parts is high, followed by professional factories, and the price of domestic products and imitations is low. Generally, the price of original parts can exceed one or two times that of imitations, and some are even higher; the parts of foreign professional supporting factories are lower than the original parts of the whole machine factory. Regular large quantities of imported parts and components to implement the agreement price negotiated with foreign investors, usually haircut to buy parts and components to implement the annual unified catalog price of foreign investors. Foreign businessmen also have preferential prices for regular processing of spare parts. The quotation of these parts is calculated according to the import exchange rate at that time, plus customs duties, transportation miscellaneous purposes, etc., converted into the unit price of parts, which is the normal price well known to the industry. Parts that are cheaper than usual can be judged as non-pure parts or professional factory parts. It should be noted that tax cuts in the import sector and price increases at intermediate dealers have also caused prices to deviate from normal standard prices.

4. according to the purchase channel analysis

At present, there are many import channels, but there are two aspects. One is directly imported from abroad, and the other is purchased from dealers. The quality of parts directly imported from foreign machinery factories and parts supporting factories is guaranteed. If the part is purchased from the sales shop, the above method is used for identification. In addition, all mechanical parts imported directly from abroad have order contracts, bills of lading, waybills, packing lists and invoices. The above formalities can be presented when purchasing parts from importing companies. Otherwise, it can be concluded that it is not an import.

In short, in the identification of imported construction machinery parts, a variety of methods, do not use a single method, according to the different types of construction machinery parts and the use of different identification methods, can be integrated use, identify the authenticity of imported parts.
