The HZT029150320 suction chamber is a core component of the HZT 15MBD marine vacuum sewage pump system. Manufactured from a single piece of 316 stainless steel using medium temperature wax casting and sandblasted and electrolytically passivated, it ensures high strength while offering excellent corrosion and rust resistance.
This component, the vacuum inlet chamber of the pump, is designed to absorb a mixed gas and liquid stream of sewage, black water, gray water, and domestic wastewater, directing the fluid to the impeller inlet. It is crucial for maintaining negative pressure and stable flow throughout the vacuum sewage system.
I. Structural and Material Advantages
* Integrated precision casting: Cast in one piece from 316 stainless steel, eliminating welds and improving pressure and seismic resistance.
* Surface treatment: Sandblasting followed by electrolytic passivation creates a uniform passivation film that resists seawater corrosion and salt spray oxidation.
* Precision interface: The front end connects to the HZT029150310 suction chamber cover, while the rear end is bolted to the HZT029150601 end flange, which is fully sealed with an HZT037219210 O-ring.
* Gas-liquid mixing flow path design: An optimized streamlined transition structure is employed internally to reduce turbulence and pressure loss, improving vacuum suction efficiency.
* Mounting method: Horizontal inline configuration for a compact structure and easy maintenance.
II. Function and System Performance
The HZT029150320’s primary function is to serve as the vacuum pump’s inlet chamber, enabling primary collection of wastewater and the suction of a mixed gas and liquid stream.
During operation, negative vacuum pressure flows through this chamber, drawing wastewater from the vessel’s vacuum toilet system, sewage tanks, or domestic wastewater collection system into the pump body.
This component plays a crucial role in maintaining vacuum, preventing air lock, and balancing pressure fluctuations.
Its high-strength 316 steel structure withstands high-frequency startups and fluid impact without deformation or corrosion, making it suitable for the long-term operating environments of ships and offshore platforms.
III. Application Industries and System Compatibility
The HZT029150320 suction chamber is widely used in:
* 🚢 Marine Sewage Treatment Systems
* ⚙️ Vacuum Toilet Systems
* 🛳️ Black & Grey Water Collection Units
* 🏭 Offshore & Port Wastewater Units
This component is designed specifically for the HZT 15MBD series vacuum pump system. While not compatible with the 25MBA, the structural principles are the same, facilitating cross-series maintenance and system upgrades.
IV. Engineering and Manufacturing Standards
HZT029150320 adheres to ISO 9001 and ISO 8099-1:2018 international standards for marine sewage disposal systems during production and has passed the following tests:
* Vacuum Tightness Test
* Salt Spray Test
* Thermal Shock Test
* Hydraulic Smoothness Inspection
HZT adheres to high-precision casting processes and anti-corrosion surface treatment technologies to ensure long-term operational stability in complex marine environments.
