Dry goods sharing, take you to understand how to distinguish true and false stainless steel water pumps
During the long-term operation of the stainless steel water pump, the wear of the bearing chamber of the water pump bearing frame, the wear of the bearing parts, the cracking of the pump body, the cavitation of the water pump, and the erosion and wear often occur. After the above problems occur, the traditional solution of the enterprise is repair welding or electric brush plating, but these two methods have certain drawbacks. The thermal stress caused by the high temperature of repair welding cannot be completely eliminated, which is easy to cause material damage, resulting in bending or breaking of parts. ; But brush plating is limited by the thickness of the coating and is easy to peel off. Moreover, the above two methods both use metal to repair metal, which cannot change the matching relationship of 'hard to hard'. Under the combined effect of various forces, it will still cause re-wear. In view of the above problems, the repair method of polymer composite materials is mostly used, which has good adhesion, excellent compressive strength and other comprehensive properties. The application of polymer material repair can avoid disassembly and machining, and the thermal stress of welding is not affected. Repair Thickness is not limited. At the same time, the metal material of the product has no concession, which can absorb the shock and vibration of the equipment, avoid the possibility of re-wear, greatly prolong the service life of the equipment parts, save a lot of downtime for the enterprise, and create huge economic value.
Dry goods sharing, one minute to show you how to distinguish true and false stainless steel water pumps
How to distinguish the true and false stainless steel water pump? Let's take a brief look at it together.
1. The product packaging of the original pump or supporting manufacturers is generally relatively standardized, with clear and formal handwriting, with detailed product name, specification and model, registered trademark, factory name, address, telephone, etc. Generally, the packaging of counterfeit accessories is relatively rough, and the factory name and address are not clearly printed.
Second, the qualified stainless steel water pump has a smooth surface and good workmanship. The more important the parts are, the higher the machining accuracy is, and the stricter the packaging is to prevent rust and anti-corrosion. When purchasing, if you find that the parts have rust spots or the rubber parts are cracked, lose elasticity, or have clear machining lines on the surface of the journal, it should not be the original one. Factory parts.
Third, the appearance of inferior pumps is sometimes good. But due to poor manufacturing process, it is easy to be damaged. When purchasing, you only need to observe the hidden parts such as the edges and corners of the accessories, and you can see the quality of the accessories technology.
Fourth, some stainless steel water pumps are refurbished with waste parts. At this time, the old paint can only be found by removing the paint on the surface of the parts. Try not to use this kind of water pump.
5. The purchased spare parts should be put into the car to see if they can be well matched with other accessories. Generally, the original parts can be well distributed to the car. The inferior parts are difficult to cooperate with each other due to poor workmanship and large processing errors. .
6. In order to ensure that the assembly relationship of the pump meets the technical requirements, some conventional parts are engraved with assembly marks on their edging surfaces to ensure the correct installation of accessories. If there is no mark or the mark is blurred and difficult to identify, it is not qualified. Accessories.
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 parts are missing, and it is easy to start to install them, which may be fake parts.
8. Some important accessories, especially the assembly, are usually accompanied by instructions and certificates to guide the user's installation, use and maintenance. Fake assemblies generally do not have detailed installation instructions to guide these.
