I. Product Positioning (Function + Assembly Relationship)
The HZT023260400 distance sleeve is a critical component in the transmission system of the HZT25MBA marine vacuum discharge pump. It maintains precise axial spacing between the HZT021265401 rotor and the HZT038281900 shaft seal, ensuring smooth operation of the rotating components under high vacuum conditions and preventing excessive seal compression.
Its core functions include:
* Controlling the distance between the rotor and shaft seal, ensuring stable dynamic and static seal fit;
* Maintaining the axial positioning accuracy of the rotor to prevent operational deviation;
* Improving overall assembly consistency and reducing mechanical wear, vibration, and noise.
The assembly relationship is as follows:
* [Motor] → [Motor Shaft] → HZT023260400 (Spacer Sleeve) → HZT038281900 (Shaft Seal) → HZT029150391 (Shaft Seal Flange) → [Pressure Chamber/Water Outlet Chamber]
II. Materials and Manufacturing Process
* Material: 316 stainless steel solid bar stock;
* Processing: High-precision CNC machining, one-step forming, ensures coaxiality and end face perpendicularity;
* Surface Treatment: Smooth surface finish in natural metal color, no sandblasting or passivation required;
* Dimensional Control: Tolerance range of ±0.01 mm, meeting the high-speed rotation and dynamic balancing requirements of the pump body;
* Fit Type: Slip-fit design, ensuring easy installation, high precision, and repeatable positioning.
III. Structure et caractéristiques techniques
1. High-Precision Axial Positioning
The inner and outer diameters are strictly coaxial, ensuring a constant distance between the impeller and the seal chamber as the pump shaft rotates.
2. Corrosion Resistance and High Strength
316 stainless steel offers excellent corrosion resistance, ensuring long-term operation in seawater, blackwater, and chemically contaminated environments.
3. Low-Wear & Long-Life Design
The sleeve’s smooth inner surface reduces shaft wear and extends the life of the entire unit.
4. Standardized Assembly Dimensions
Compatible with the full range of 25MBA components (HZT023219000 / HZT023219100 / HZT029150391), enabling direct replacement and maintenance.
