Detailed Explanation Of Casting Process For Intermediate Bowl

Oct 31, 2024

1, Overview
The intermediate bowl is an important functional component of submersible pumps, which plays a crucial role in ensuring the safe and stable operation of the fluid pumped by the intermediate bowl. This article provides a detailed introduction to the specific steps and technical points of the intermediate bowl casting process.

2, Raw material selection
The selection of intermediate bowl material has a decisive impact on the structure and properties of the intermediate bowl. Intermediate bowl is generally made of iron or stainless steel materials, and special high-temperature alloy materials such as chromium, molybdenum, and other metal materials are added for manufacturing. At the same time, factors such as the thickness and density of the intermediate bowl need to be considered to ensure its strength and stiffness.

3, Intermediate bowl casting process
1. Model making: First, make the 3D drawing of the intermediate bowl into a solid model.

2. Mold making: Make a mold based on the solid model of the intermediate bowl, and press the filling material inside the mold to ensure the density and uniformity of the filling material.

3. Melting: Melt the selected high-temperature alloy material and pour it into the mold for melting, ensuring uniform melting and avoiding hot cracking.

4. Cooling: After the casting is completed, place the mold in a naturally ventilated place for cooling, and do not remove it in a hurry.

5. Mold release: After cooling, open the mold and remove the intermediate bowl. At this point, the intermediate bowl is still in a semi-finished state and requires further processing and handling.

6. Side pressing and machining: Perform side pressing and machining on the intermediate bowl to ensure its surface smoothness and dimensional accuracy.

4, Precautions
1. Choose appropriate materials and manufacturing processes to avoid strong thermal deformation and frictional wear of the intermediate bowl during high-speed movement, which can lead to safety issues such as equipment damage.

2.During the casting process, it is necessary to ensure that the casting temperature is appropriate, control the casting time and pressure parameters, and avoid defects such as porosity, inclusions, and cracks.

3. Adopt natural ventilation method for mold cooling to avoid intermediate bowl deformation and cracking caused by rapid cooling and other methods.

When performing machining, it is necessary to ensure the stability of the machine tool and the accuracy of the machining parameters, and avoid vibration interference during the machining process.

【 Conclusion 】

The intermediate bowl casting process is a tedious task that requires professional knowledge and skills. Only by selecting suitable materials and manufacturing processes and mastering the key technologies of each step can we ensure that the quality and performance of the intermediate bowl meet the requirements.
