1. Descripción general del producto
The HZT021201000 knife holder is one of the core mechanical support components of the 25MBA marine vacuum sewage pump. It primarily secures the stationary knife assembly (HZT020203100), maintaining the coaxial accuracy of the knife assembly and rotor (HZT021265401) in high-vacuum fluid environments.
This component, with its high-strength structural design and dynamic balancing, effectively prevents cutting offset and vibration, making it a critical component for ensuring smooth pump operation and extending the life of the knife assembly.
It is widely used in ships, yachts, offshore platforms, and land-based vacuum toilet systems. It is an indispensable precision component in the assembly of the 25MBA series vacuum pumps.
2. Materiales y artesanía
The knife holder is precision-machined from 316 stainless steel, with a sandblasted and electropolished surface for excellent corrosion resistance.
During the manufacturing process, the bracket is formed in one go using a high-precision five-axis CNC machining center. Key mating holes and positioning surfaces undergo secondary finishing, achieving a flatness accuracy of less than 0.01mm.
The material properties ensure it will resist rust and deformation during long-term use in blackwater, seawater, and humid vacuum environments, meeting the long-term continuous operation requirements of marine vacuum systems.
All finished products undergo dynamic balancing testing and assembly calibration to ensure stable operation at a G2.5 dynamic balance level.
3. Estructura y características técnicas
a) Overall rigid structure provides excellent vibration resistance and stability.
b) 316 stainless steel is used for corrosion resistance, making it suitable for marine and sewage environments.
c) Precision CNC machining ensures precise assembly of the stator blade and rotor, maintaining pump body coaxiality.
d) The rational structural design allows for easy installation and maintenance, minimizing adjustment errors.
e) Dynamic balancing level G2.5 is suitable for high-speed vacuum pump applications. Once installed, the knife holder forms a precise cutting system with the fixed blade, rotor, and housing, ensuring smooth fluid circulation, low noise, and stable operation within the vacuum pump.
4. Aplicaciones
a) Marine Vacuum Discharge Pump systems for ships and yachts.
b) Vacuum wastewater treatment systems for passenger ships, cruise ships, offshore platforms, and drillships.
c) Land-based construction, recreational vehicles (RVs), and environmentally friendly vacuum toilet systems.
d) Industrial wastewater and blackwater treatment and vacuum conveying equipment.
This component is widely used in water-saving, sealed, and low-maintenance vacuum systems and is compatible with major international vacuum system interfaces.
