The HZT029151900 locking nut is a critical fastening and sealing component at the inlet of the HZT 15MBD marine vacuum sewage pump system.
This nut is installed above the HZT029151001 flap valve base. By tightening and compressing the HZT037219210 O-ring below, it securely seals the entire flap valve assembly against the HZT029150320 suction chamber, completing the inlet seal structure of the vacuum pump head.
I. Structure and Manufacturing Advantages
* CNC Precision Turning:
The entire assembly is precision-turned from 316 stainless steel bar stock, resulting in high thread precision and excellent surface finish.
* High-Strength Internal Thread Structure:
The internal thread tightening design provides reliable axial preload, preventing loosening during vacuum operation.
* Sealing and Compression Function:
The lower flat surface cooperates with the O-ring to form a resilient seal, ensuring no gas or liquid leaks in the system.
* Corrosion Resistance:
316 stainless steel offers excellent resistance to salt spray, acid, alkali, and seawater corrosion, making it suitable for harsh marine environments.
* High-Precision Coaxiality:
Ensures concentricity with the flap valve base and suction chamber, maintaining smooth fluid flow and stable vacuum.
II. Function and System Function
HZT029151900 is a core fastening component in the inlet sealing system of the vacuum pump head. Its functions include:
* Tightening the threads to compress the sealing ring to create a vacuum seal;
* Stabilizing the flap valve assembly to prevent loosening due to operating vibration;
* Ensuring a vacuum seal and gas-liquid isolation in the upper suction chamber;
* Facilitating assembly and disassembly, improving system reliability and serviceability.
This lock nut plays a crucial role in ensuring the airtightness of the vacuum suction section and is a key component in ensuring overall system performance.
III. Application Areas and Industry Expansion
HZT029151900 is widely used in:
* 🚢 Marine Sewage and Blackwater Vacuum Collection Systems
* ⚙️ Vacuum Toilet Systems
* 🛳️ Offshore Wastewater Treatment Systems
* 🧰 Marine Vacuum Sewage Pump Assemblies
Its high strength, corrosion resistance, and precision sealing make it an ideal structural component for long-term operation in humid, salt spray, and high-vacuum environments.
# 4. Manufacturing Standards and Testing
HZT029151900 is manufactured in accordance with ISO 9001 and ISO 8099-1:2018 international standards and undergoes rigorous testing:
* Thread Tolerance & Alignment Test
* Sealing Test
* Salt Spray Test
* CNC Machined Surface Roughness Inspection
HZT ensures that every lock nut meets the high standards for long-term, safe operation of marine vacuum systems.
