What Is the Reason for Frequent Water Leakage in Gray Iron Pump Housing?
Gray iron pump housing has good mechanical properties and low cost, and is widely used in various water pump products. However, some users have reported that some gray iron pump houses frequently leak water during use, which not only affects normal production, but may also cause safety risks. Why does gray iron pump housing leak frequently?
After analysis, we found that there are three main reasons for the leakage of gray iron pump housing. Material problems are the primary reason. Some manufacturers use inferior raw materials to reduce costs. The cast iron is very loose and has tiny pores. It may also be a problem with the casting process. If the sand mold casting process is not well controlled, it is prone to shrinkage and other problems. In the end, it may be that the machining accuracy is insufficient, the sealing surface is unqualified or the flange connection part is wrong, which will affect the final sealing effect.
For these problems, our company has established a pump shell quality control system. In terms of raw materials, we use high-quality pig iron and spheroidizing agents, and purchase instruments for composition testing, so that the internal organization of gray iron pump housing is tight and not damaged. And we can provide customers with customized services. According to different working conditions, we can adjust the wall thickness design of the pump housing and the flange connection method. For example, for sand casting pump housing that transports corrosive liquids, we will increase the surface coating to improve the corrosion resistance; for sand casting pump housing that transports high-temperature liquids, we will adjust the alloy composition in the material to enhance the high temperature resistance. Many customers have feedback after using our pump housing, and the problem of water leakage has been reduced, and the operating stability of the equipment has also been improved. Our engineering team will understand the specific use conditions of each customer in detail to design to meet the needs of customers.
Dandong Fuding Engineering Machinery Co., Ltd. there is a professional production workshop, from sand mold making, molten iron pouring to late cleaning and polishing, each link has a special person responsible for inspection to ensure that the sand casting pump housing that leaves the factory is free of pores, cracks and other damage. Whether it is the pump housing of a small agricultural pump or the pump housing of a large industrial water pump, we can complete the production on time.
We believe that by optimizing the casting process, supervising the production process and providing personalized solutions, the problem of water leakage in sand casting pump housing can be reduced. We will continue to conduct research on casting technology and testing equipment to provide customers with reliable pump housing products.
