Look at the logo, weight and specifications. When purchasing agricultural machinery products and accessories, it is necessary to have a trademark awareness and choose Guoyou and Buyou brand-name products. When you purchase accessories, you must first observe whether the accessories specifications meet the requirements. Although some are almost the same from the outside, but do not pay attention to buy it back can not be used. Secondly, we must measure the amount of helium by hand. Most shoddy parts are cut corners, light weight and small size. We must pay attention to identification.
Second, look for product certification and assembly marks. Authentic products are certified by the National Quality and Technical Supervision Department, approved for production, inspection and certification, instructions, and installation notices, if not more than fake and shoddy products. Authentic and qualified product assembly marks are very clear and obvious. Such as the formal gear assembly mark, the top mark of the piston should be clear and clear. Unmarked and unclear marks must not be used.
Look for cracks and distortions. The counterfeit and inferior products are viewed from the appearance and have a low gloss, and there are obvious defects such as cracks, sand holes, slag inclusions, and burrs, which easily lead to failures such as oil leakage, water leakage, and air leakage. In addition, tires, V-belts, shafts, rods, etc., if the storage method is not appropriate, it is easy to produce deformation, geometrical dimensions can not meet the requirements of the use of regulations, it can not be used normally.
Four to see if there is rust and loose, stuck. Qualified products, assembly parts turn flexibly, the gap size meets the standard specification. Most of the shoddy products are not too loose, that is, they are not flexible. Some parts and accessories may be rusted, oxidized, discolored, deformed, or aged due to poor storage or long storage time. If you have any of the above conditions, you should not purchase it.
Look at the appearance of the packaging and the surface color. Authentic product packaging emphasizes quality, products are rust-proof, waterproof, anti-corrosion treatment, using wooden packaging, and marked on the obvious product name, specifications, model, quantity and name. Some parts assemblies are packed in paper cartons and set in plastic bags. Fake and shoddy product packaging is rough and poor. If it is a manufacturer's original product, the surface coloring treatment is relatively fixed, and all of them are regulated colors. Therefore, the appearance of the agricultural machine can also be seen from the appearance.
