The HZT029150800 rotor housing is a key component in the HZT 15MBD marine vacuum sewage pump system. Its primary function is to create a vacuum chamber and protect the rotor (HZT029150701), ensuring stable rotation under high negative pressure and fluid flow conditions.
This component is precision-turned from seamless 316 stainless steel tubing through CNC machining. Its smooth interior and high coaxiality ensure the system’s vacuum performance and reliability.
I. Structure and Design Features
* Monolithic Cylindrical Structure
The rotor housing is machined from a seamless tube, eliminating welds to prevent leakage and deformation, ensuring high vacuum tightness.
* Precision Inner Bore
The inner bore undergoes CNC precision turning and electrolytic treatment, achieving a surface roughness of Ra0.8, ensuring smooth rotor operation and zero eccentric vibration.
* High Concentricity Design
Coaxial assembly with the rotor (HZT029150701) and end flange (HZT029150601) ensures stable operation after dynamic balancing (G2.5).
* Surface Finish
The brushed finish provides corrosion resistance and enhances the appearance, reflecting the HZT brand’s high-quality manufacturing process.
II. Manufacturing Process
1. Material: 316 stainless steel (Grade A4)
Excellent resistance to chloride ion corrosion, suitable for long-term use in marine and humid environments;
2. Processing: CNC Precision Turning
Molded from a single piece of seamless stainless steel pipe, the tube is clamped and formed in one go, ensuring precise inner and outer diameter coaxiality;
3. Surface Treatment: Brushed finish
Enhanced corrosion and stain resistance, preventing the adhesion of impurities from wastewater;
4. Inspection: Dimensional inspection + coaxiality inspection + inner wall roughness inspection
Ensures assembly accuracy meets HZT internal vacuum system standards.
III. System Function and Assembly Relationship
The rotor housing (HZT029150800) serves as the central pressure-bearing chamber of the pump body. Its front end is connected to the cutting unit via an end flange (HZT029150601), housing the rotor (HZT029150701). Its rear end connects to the pressure chamber (HZT029150901), forming a single-piece vacuum flow path for suction, shearing, rotation, and discharge.
During operation, the rotor housing:
* Supports high-speed rotor rotation and ensures stable clearance within the impeller cavity;
* Withstands gas-liquid mixed pressure and mechanical vibration;
* Provides a sealed chamber to prevent leakage and external contamination;
* Reduces energy consumption and turbulence through a smooth flow path.
IV. Performance and Application
* High-precision structure: Ensures stable system dynamic balance;
* Excellent corrosion and rust resistance**;
* Strong assembly compatibility: 25MBAs in the same series share the same structure (different dimensions), allowing for system modification or upgrades;
* Applications:
🚢 Marine vacuum sewage and blackwater systems
⚙️ Vacuum toilets and domestic sewage installations
🧰 Port and offshore wastewater systems
