Buy agricultural machinery has tips
Many farmers' friends first purchased agricultural machinery products and often faced with many brands of products. Here are a few ways to do it. Select the brand. In general, brand-name companies are relatively large-scale, R&D capabilities and quality assurance conditions are relatively strong; product quality is relatively stable, and three-package services are relatively timely. Look at the effect. Before buying, please consult with people who have such machinery, compare several brands, understand the performance, quality, after-sales service and other conditions of the products to be purchased. See documents. The certified products are subject to inspection and control, and the product quality is relatively guaranteed. Certified products are affixed with badge signs. Special attention should be paid to the fact that some companies have several types of products. One product may be certified, and other models may not be certified. Look at the appearance. In general, the appearance of the product reflects the inherent quality of the product to some extent. Observe whether the product has bumps, damages, paint stripping and signs of refurbishment; whether the welds at each welding site are smooth and firm; whether the sealing surface is leaking oil; whether the gaps of all parts are the same; whether the castings, such as the box, have cracks and pores. Blisters and other defects. Look at the logo. The product name, model number, main technical parameter, execution standard number, and name, address, contact telephone number, postal code of the manufacturer on the nameplate, as well as the product serial number and date of manufacture must be complete. Warning signs, such as protective covers, that may pose a hazard are mandatory standards. Operate position marks on or around the operating element. The complete identification not only reflects the strict implementation of corporate standards, but also facilitates user operations. Be careful when purchasing products that have a long delivery date, long-term storage, or rework. See instructions. Manual product model, name, implementation of standard number, safety warning content, model meaning, main scope of application, main technical parameters, performance and maintenance, faults and queuing must be complete. The content of the warning should be highlighted; the address of the manufacturer must be the same as that on other documents and on the nameplate. If there is no production company address or contact phone number is just a mobile phone number, such products are often produced by informal enterprises and should not be purchased. Look at the service. The products produced by regular enterprises all have three packs of certificates. The above not only shows the instructions for Three Guarantees maintenance, but also provides three packs of maintenance record forms; it is necessary to explain the warranty period of Three Guarantees and the contact address and telephone number of Three Guarantees maintenance units. The perfect Three Guarantees Service is an effective guarantee for the use of products and can relieve users of their worries. See protection. Most agricultural machinery must have protective measures. This is a national mandatory standard. For this reason, you must choose products that have reliable protective measures, have hidden dangers, and have warning signs. This will not only ease the use but also avoid accidents. If some product protection cover is optional, do not try to save the protection cover and use it for your own use. Look at the price. Select products according to their own ability and functional needs, appropriate price comparison. If the price of the same type of product is too low, the quality of such machines is often difficult to guarantee. In similar products, it is recommended to buy a mid-priced product. For the same brand and model product, under the premise of eliminating the inventory machine and returning machine, compare the distributors and select the products with relatively low prices. Test run. One must start the performance check. It is necessary to start the engine several times in succession to check the starting performance. The second is the empty operation check. Under normal operating speed, run continuously for more than a quarter of an hour to check if the machine is running smoothly, with or without abnormal sound. After the end of the operation, check whether there is any oil leakage on the joint surface and the sealing surface; whether there is overheating in each bearing position and the transmission case. The third is to check the operating performance. Actually operate the machine to check whether the operation is convenient or not. If you cannot test the machine, you can manually check the operation of the machine and check whether the rotating parts are flexible and have any stagnation.
