The HZT029150701 rotor is the core drive component of the HZT 15MBD marine vacuum sewage pump system.
It determines the vacuum limit, gas-liquid separation stability, and operating noise level of the entire system, and is a key foundation for system performance.
I. Structure and Design Logic
* Single Helical Rotor:
Adopting a right-hand helical rotor design, the rotor generates vacuum suction through the suction and push action of the rotor blades during fully submerged operation.
* Optimized Fluid Guide Design:
Blade angles and flow channel curvatures are optimized through fluid simulation to ensure smooth flow of wastewater, reduce turbulence and cavitation, and improve the system’s ultimate vacuum value and efficiency.
* Installation:
Connected to the motor shaft via a spacer sleeve (HZT029151800), the blade assembly (HZT029150450) is mounted in front, and the rear portion cooperates with the pressure chamber (HZT029150901) to form a vacuum flow channel.
# 2. Manufacturing Process and Dynamic Balancing Control
* Medium-Temperature Wax Precision Casting (IPC):
Ensures uniform blade thickness and precise flow channel formation, providing a geometric foundation for subsequent dynamic balancing.
* CNC Precision Machining:
Blades and center holes are machined using multi-axis turning and milling to ensure coaxiality and static and dynamic clearances.
* Single-Unit Dynamic Balancing (G2.5) (ISO 1940 Standard):
Each HZT029150701 rotor is individually balanced to G2.5 and numbered to ensure low-vibration operation.
* Sandblasting & Electropolishing:
The surface is clean and smooth, preventing the adhesion of fibers and particles in wastewater, effectively reducing drag and scaling.
III. Performance and System Functions
The HZT029150701 rotor performs two functions during vacuum pump operation:
1. Creating Vacuum and Suction:
The spiral motion of the blades creates a negative pressure area within the liquid, allowing the mixed wastewater and gas to be drawn in.
2. Maintaining a Stable Discharge Flow:
The fluid is pushed into the pressure chamber (HZT029150901), where the impeller rotates to maintain a stable flow rate and pressure, preventing air locks.
3. Serving as a Cutter Breaking System:
The front-mounted blade assembly (HZT029150450) crushes impurities before the rotor draws in fluid, ensuring smooth, unobstructed fluid flow.
4. Maintaining System Balance and Quiet Operation:
Precise dynamic balancing ensures low vibration and noise, extending the life of bearings and seals.
IV. Materials and Corrosion Resistance
* 316 stainless steel, highly resistant to chloride ion corrosion;
* Surface electrolytic passivation layer improves corrosion resistance and finish;
* Suitable for use in environments with seawater, domestic sewage, and mild chemical media;
* Ensures long-term stable operation in high humidity, high salt spray, and high vibration conditions.
