Engineering Department

The Engineering Department at Hamgam Sanat Company plays a key role in ensuring the quality and performance of the company’s equipment through design, modeling, and optimization. Leveraging technical expertise and international standards, this department precisely manages the processes of design and production.

Drawing and Modeling Process

At Hamgam Sanat, the drawing and modeling process for decanter centrifuges and cooling tower pumps includes the following steps:

  1. Measurement and preparation of initial sketches
  2. Design and creation of 3D computer models
  3. Assembly modeling with adjacent components
  4. Preparation of manufacturing drawings according to standards
  5. Selection and specification of dimensional and geometric tolerances

Impellers

Impellers in Hamgam Sanat cooling tower pumps vary significantly depending on size and type:

  • Gravity-cast impellers: These are first scanned and converted into 3D models. Manufacturing drawings are then prepared, followed by casting using the model. After casting, the component is analyzed and, if approved, sent for machining.
  • Precision-cast impellers: Similar to gravity-cast impellers, except the casting model is made of wax, which is eliminated during the molten metal pouring process.

Gears

Gears in Hamgam Sanat decanter centrifuge gearboxes are categorized based on type and function. The manufacturing process varies: some require surface hardening, others special coatings, and some need precision grinding.

Component Balancing

Rotating components, particularly in decanter centrifuges, require weight balancing due to their geometry and manufacturing method. Improper balancing can cause vibration, noise, and reduced component lifespan.

  • Hamgam Sanat uses the ISO 1940 balancing standard, recognized across industries.
  • After balancing, a certificate is issued for each component, and the conditions are documented and archived.

The Engineering Department at Hamgam Sanat ensures optimal performance and durability of equipment through precise design, production, and quality control processes, providing a solid foundation for innovation and product development.
