How much do you know about sewage pumps? Today, we will discuss with you how to distinguish whether a sewage pump is a refurbished pump, in order to enhance our understanding of cutting sewage pumps.
1、 The packaging of original sewage pumps or supporting manufacturers is generally standardized, with clear and formal handwriting, detailed product names, specifications and models, registered trademarks, factory names, factory addresses, and phone numbers; Counterfeit accessories usually have thicker packaging, and the printing of the factory address and name is unclear and incomplete.
2、 Qualified sewage pumps have a smooth surface and good workmanship. The more important the spare parts are, the higher the processing accuracy, and the stricter the packaging for rust prevention and corrosion prevention. If rust spots, rubber cracking, loss of elasticity, or visible machining patterns on the surface of the shaft neck are found on the parts during purchase, they should not be original accessories.
3、 Poor quality sewage pumps sometimes have a good appearance. However, due to poor manufacturing technology, it is easy to be damaged. When purchasing, simply observe the hidden parts such as edges and corners of the accessories to see the quality of the accessory craftsmanship.
4、 Some sewage pumps are refurbished from discarded parts, and in this case, the old paint can be found by removing the surface paint of the parts. Such sewage pumps should be avoided as much as possible. The use of refurbished parts such as brake systems and driving system components can easily lead to danger.
Fifth, when installing purchased spare parts into the car, it depends on whether they are compatible and whether the parts are well matched. Generally, original factory parts can be well allocated to the vehicle, but low-quality parts are difficult to match well due to poor craftsmanship and large processing errors.
Sixth, to ensure that the assembly relationship of the sewage pump meets technical requirements, some formal parts are engraved with assembly marks on the surface to ensure the correct installation of accessories. If there are no marks or the marks are unclear and cannot be recognized, they are not qualified accessories.
Seventh, a formal sewage pump assembly and components must be complete and intact to ensure smooth installation and normal operation. Some small parts on the assembly are missing, which can easily cause difficulties in starting the vehicle. These parts may be counterfeit parts.
Eighth, some important accessories, especially assemblies, usually come with instructions and certificates of conformity when leaving the factory to guide users in installation, use, and maintenance. Fake assemblies generally do not have detailed installation instructions to guide these.
