During long-term operation, stainless steel water pumps often experience wear on the bearing housing of the pump bearing frame, wear on the bearing parts, cracking of the pump body, cavitation and erosion wear of the pump. After the above problems occur, the traditional solutions for enterprises are repair welding or electric brush plating, but both methods have certain drawbacks. The thermal stress generated by high temperature during repair welding cannot be completely eliminated, which can easily cause material damage and lead to bending or fracture of parts; However, brush plating is limited by the thickness of the coating and is prone to peeling off. Moreover, both of the above methods use metal to repair metal, which cannot change the matching relationship of 'hard to hard'. Under the comprehensive action of various forces, it will still cause re wear.
In response to the above issues, polymer composite materials are often used for repair, which have good adhesion, excellent compressive strength and other comprehensive properties. The application of polymer material repair can avoid disassembly and machining, welding thermal stress is not affected, and the repair thickness is not limited. At the same time, the metal material of the product does not have yielding properties, which can absorb the impact and vibration of the equipment, avoid the possibility of further wear and tear, greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create huge economic value.
How to distinguish between genuine and fake stainless steel water pumps?
Let's all take a brief look together below.
1, The packaging of original pumps or supporting manufacturers' products is generally standardized, with clear and formal handwriting, detailed product names, specifications, registered trademarks, factory names, addresses, telephone numbers, etc. The packaging of counterfeit accessories is generally rough and does not clearly print the factory name and address.
2, Qualified stainless steel water pumps have smooth surfaces and good workmanship. The more important the component, the higher the processing accuracy, and the stricter the packaging rust and corrosion prevention. When purchasing, if rust spots or rubber parts crack, lose elasticity, or there are clear processing lines on the journal surface, it should not be an original factory part.
3, The appearance of inferior pumps is sometimes good. But due to poor manufacturing processes, it is easily damaged. When making a purchase, simply observe the hidden parts such as the edges and corners of the accessories to see the quality of their technology.
4, Some stainless steel water pumps are refurbished with waste parts. At this point, the old paint can only be found by removing the paint on the surface of the parts, so try not to use this type of water pump.
5, The purchased spare parts need to be installed in the car, and it depends on whether they can be well matched with other parts. Generally, original factory parts can be well allocated to the car, while inferior parts are difficult to match due to poor workmanship and large processing errors.
6, In order to ensure that the assembly relationship of the water pump meets the technical requirements, some conventional parts are engraved with assembly marks on their edges to ensure the correct installation of accessories. If there is no mark or the mark is unclear and difficult to identify, it is not a qualified accessory.
7, The regular water pump assembly and components are in good condition to ensure smooth loading and normal operation. Some small parts on the assembly components are missing and easy to install, which may be fake parts.
8, Some important accessories, especially assemblies, are usually accompanied by instructions and certificates of conformity to guide users in installation, use, and maintenance. Fake assemblies generally do not have detailed installation instructions to guide them.
