Description

Technical Field

[0001] This utility model relates to the field of casting pump body technology, specifically a metal casting pump body that is easy to install. Background Technology

[0002] In the field of industrial production and fluid transmission, metal casting pump bodies are one of the key pieces of equipment. Their ease of installation, connection stability, and sealing performance directly affect the operating efficiency and reliability of the entire system. Traditional metal casting pump bodies often suffer from problems such as inaccurate positioning, cumbersome installation steps, loose connections, and poor sealing performance during installation.

[0003] Specifically, traditional pump bodies typically rely on manual alignment and adjustment during positioning, which not only increases installation difficulty but also easily leads to installation errors, affecting the normal operation of the pump body. At the same time, traditional pump bodies often lack effective positioning devices between connecting flanges, making it easy for relative slippage to occur during the connection process, resulting in an unstable connection and even causing safety accidents.

[0004] In addition, the connecting bolts of traditional pump bodies are prone to loosening or falling off during long-term use. This not only affects the stability of the pump body, but may also lead to leakage at the connection, causing pollution to the production environment. Poor sealing performance is also a major drawback of traditional pump bodies. Liquid or gas leakage not only wastes resources, but may also damage equipment and even endanger personnel safety.

[0005] To address the aforementioned issues, we propose a metal casting pump body that is easy to install. Utility Model Content
