In the process of making the pump and valve castings, the principle of casting position selection, the important processing surface of the product or the main processing surface facing down or on the side, the casting position of the machine bed should face the rail face down to ensure the importance The quality of the work surface. The quality of the circumferential surface is relatively high. The vertical casting scheme is adopted to make the circumferential surface on the side to ensure uniform quality.
Technical requirements for pump and valve castings
1. The development of pump and valve casting simulation technology can effectively improve the accuracy of its prediction, strengthen process control and improve the yield. The problem of regularity is not well mastered, thus affecting the yield in mass production.
2. In addition to the increase in the awareness of independent innovation of pump and valve castings and the improvement of research and development capabilities, it is also necessary to attach importance to and strengthen the combination of “production, learning and research” with precision casting enterprises as the main body.
3. Pay attention to the improvement of equipment technology. The process is mainly a matter of equipment. Many key equipments, such as some directional solidification equipment, mainly rely on imports.http://www.pump-casting.com/
