Professional Introduction to High Water-Based Packing

High Water-Based Packing is a new type of sealing packing centered around a water-soluble lubrication system, specifically designed as a green sealing solution for modern environmental requirements. Utilizing innovative composite material technology, this product is perfectly adapted for working environments with water as the primary medium.

Core Advantages and Features

1. Environmentally Friendly Water-Based Formulation:

   • Utilizes an oil-free water-based lubrication system (water content >60%).

   • Contains no mineral oils or heavy metals; certified to RoHS standards.

   • Biodegradation rate >90% (OECD 301B standard).

2. Outstanding Performance:

   • Wide temperature adaptation range (-20°C to 280°C).

   • Low friction coefficient, down to 0.05 (under water-lubricated conditions).

   • Features self-repair functionality, automatically releasing lubricating components upon wear.

3. Special Structural Design:

   • Three-layer composite fiber braided structure (wear-resistant surface layer / sealing middle layer / lubricating base layer).

   • Intelligent water-absorption expansion characteristic (expansion rate controllable within 3-5%).

   • Built-in slow-release microcapsule technology (continuously releases lubricating components).

Product Series Description

• Economy Type: Suitable for general water pumps (service life 8,000-10,000 hours).

• Enhanced Type: Contains ceramic fibers, improving pressure resistance by 40%.

• High-Temperature Special Type: Graphite-modified, with a service life of up to 15,000 hours in steam applications.

• Food Grade: Certified to NSF/ANSI 61 for potable water.

Typical Application Scenarios

• Water Treatment Systems: High-pressure plunger pumps, multi-stage centrifugal pumps.

• Energy Equipment: Boiler feed pumps, cooling circulation systems.

• Food Industry: Beverage filling equipment, CIP cleaning systems.

• Marine Engineering: Seawater desalination units, ballast pumps.

Professional Installation Guide

1. Pre-treatment Requirements:

   • Shaft surface hardness ≥ HRC45.

   • Sealing chamber cleanliness must reach ISO 4406 16/14 level.

2. Installation Process:

   • Employ the "Rule of Three" installation method (check compression every 3 rings).

   • Use specialized hydraulic tools (pressure control: 5-8 MPa).

   • Final compression should be controlled at 18 ± 1%.

3. Running-in and Commissioning:

   • Initial start-up requires pre-lubrication with water (30 minutes).

   • Run-in period speed should be controlled at 60% of the rated value.

   • Re-check tightening force after 48 hours.

Maintenance Specifications

• Routine Inspection:

  • Record leakage weekly (normal range: 50-150 ml/h).

  • Measure stuffing box temperature monthly (ΔT should be < 15°C).

• Preventive Maintenance:

  • Replenish water-based lubricant every 2,000 hours.

  • Perform compression check every 5,000 hours.

• Replacement Criteria:

  • Continuous leakage > 300 ml/h.

  • Friction torque increase > 30%.

  • Visible delamination or hardening occurs.

Technical Breakthrough Highlights

1. Intelligent Response Technology:

   • Temperature-sensitive lubricant (automatically adjusts viscosity with temperature rise).

   • Pressure-activated sealing mechanism (density increases by 20% when pressure > 1 MPa).

2. Environmental Innovation:

   • Utilizes plant-based fiber materials.

   • Designed for recyclability (recycling rate > 80%).

3. Energy Efficiency Benefits:

   • Reduces shaft power loss by approximately 25%.

   • Decreases cooling water consumption by 30-50%.

High Water-Based Packing represents the development direction of a new generation of sealing materials, particularly suitable for modern factories requiring a balance between performance and environmental protection. Its unique "water instead of oil" technology not only meets the strictest environmental regulations but also significantly reduces users' overall maintenance costs, making it an ideal replacement for traditional oil-based packing.
