Vigilance: traps for agricultural machinery spare parts
Snare 1: Material fish eyeballs The current use of materials for agricultural machinery spare parts is inferior and superior, and it is more common to pretend to be false. In recent years, it has become increasingly fierce and revamped. Some shoddy bearings actually use cast iron brackets instead of copper brackets; Piston pins replace high-quality alloy steels with gray cast iron at 20°C; Ordinary triangular tapes use reclaimed rubber instead of industrial ones, replacing poorly-provided cords with qualified cords; Rail steel rolling blanks; hammers are instead of ordinary carbon steel instead of high-quality carbon steel. Trap two: good or bad injector is one of the three precision components of the diesel injector, and its quality directly affects the power and economy of the diesel engine. In the same S195 diesel engine, the fuel consumption of the qualified nozzle is 2549g/kw.h, and the fuel consumption of the poor nozzle is 2599g/kw.h. The poor fuel nozzle not only consumes more than 5g/kw.h of fuel, but also the diesel engine is prone to overheating, carbon deposition, and excessive emissions. Trap 3: Fragile knuckle steering knuckle is a safety part for tractors and agricultural four-wheeled transporters. After high-quality carbon alloy steel is used to forge the blank, strict heat treatment is required to ensure its use. At present, some are made of cast steel, and some are made of ordinary carbon steel (without heat treatment). This will inevitably lead to malignant accidents. Not long ago, when a tractor was driving, due to a steering knuckle rupture, the tractor turned into a 3 meter deep ditch, causing scrapping and two youths died on the spot. After investigation, the steering knuckle is a poor quality product produced by Chen Mou of Ningjin County, Hebei Province. The fracture has obvious pores and trachoma. Trap 4: Propaganda overstatement Some agricultural transport vehicles are equipped with high-power engines and large cars. When sales are performed, the salesperson says that the vehicle has a large horsepower and pulls far more, exaggerating the carrying capacity of agricultural vehicles. After the farmers purchased, the phenomenon of overloading during use was very serious, accidents also occurred frequently, and other problems were solved to seek “Three Guaranteesâ€. The after-sales service personnel definitely believed that it was caused by overload, because the carrying capacity of the manual was 0.5 tons. This is a fraud in the overall design and sales process. Trap five: no invoice no "Three Guarantees" In the agricultural machinery spare parts market sales, the phenomenon of no formal invoices is widespread, especially the parts and parts do not open a formal invoice. When the peasants bought the fake agricultural machinery and had an accident, complained or sued to the court, the seller did not confess because there was no evidence. Peasant consumers lost their suits and suffered from a loss. In addition, after-sales service does not give the user a record of "three packs of cards." This should be the implementation of "Three Guarantees" parts, service personnel to allow consumers to buy their own, etc. are also common occurrences. No invoice, no "three guarantees" seriously infringed the rights and interests of consumers.
