Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a cam rotor pump spraying device. Background Art

[0002] In modern industrial production, rotary lobe pumps, known for their efficient and stable transfer of high-viscosity fluids, are widely used in the chemical, food processing, pharmaceutical, and spray painting industries. These pumps utilize a sophisticated mechanical structure—including the interaction between a rotating rotor and a stationary cam—to precisely pump and discharge fluids, making them key equipment for ensuring continuous and uniform material transfer. However, maintaining rotary lobe pumps, particularly for surface corrosion protection, presents a number of technical challenges and drawbacks when using traditional spray painting techniques.

[0003] Uneven spraying and masking challenges: The lobe rotor pump has a complex structure, containing numerous delicate mechanical components such as rotors, cams, and gears, all of which have tight clearances between them. Precisely controlling the uniformity of the paint layer during surface painting is particularly challenging, especially around moving parts, where complete coverage is often difficult to achieve while also avoiding overspray that can cause moving parts to become stuck. Furthermore, masking is a tedious process to protect the pump's core components from paint contamination. This is not only time-consuming and labor-intensive, but can also lead to incomplete painting and subsequent cleaning difficulties due to inadequate masking.

[0004] Risks affecting pump performance: Improper spraying operations may cause paint to penetrate into the pump and adhere to moving parts such as the rotor and cam. This will not only increase wear, but may also change the original clearance of the pump, affecting its normal operation and pumping efficiency. In severe cases, it may even cause damage to the pump body.

[0005] In order to solve the above technical problems, the present utility model designs a cam rotor pump spraying device. Utility Model Content
