| Parameter Category | Specific Parameter | Detailed Description |
|---|---|---|
| Basic Information | ||
| Seal Type | Mechanical Seal QT-250 | Specifically designed for various industrial pumps and equipment to provide reliable sealing performance, ensuring the stable operation of the system and preventing medium leakage. |
| Brand | [Brand Name] (to be filled according to actual situation) | |
| Model | QT-250 | This model is carefully engineered to meet specific performance requirements and installation dimensions in relevant applications. |
| Materials | - Rotating Ring: Silicon Carbide (SiC) - Stationary Ring: Aluminum Oxide Ceramic - O-ring: Fluoroelastomer (FKM) |
Silicon carbide for the rotating ring offers high hardness and excellent wear resistance, enabling it to withstand harsh working conditions. The aluminum oxide ceramic stationary ring provides good corrosion resistance. The FKM O-ring ensures a tight seal and is resistant to a wide range of chemicals. |
| Size Specifications | ||
| Shaft Diameter Range | 30 - 60 mm | Can be adapted to different pump shaft diameters within this range, providing flexibility for various installation scenarios. |
| Seal Chamber Inner Diameter | 40 - 70 mm | Matches with the inner diameter of the seal chamber of the corresponding pump or equipment to ensure a proper fit and effective sealing. |
| Seal Width | 10 mm | This width is optimized to balance the sealing performance and the mechanical strength of the seal, enhancing its durability. |
| Performance Parameters | ||
| Working Pressure | Maximum 2.0 MPa | Under normal working conditions, the seal can effectively maintain its sealing function within this pressure limit, preventing the leakage of the medium inside the system. |
| Working Temperature | -30ºC - 180ºC | Capable of operating in a wide temperature range, making it suitable for applications where temperature variations are significant, such as in chemical processing or thermal systems. |
| Linear Velocity | Maximum 12 m/s | When the pump or equipment is running at a high speed, the seal can still maintain its integrity and sealing performance up to this linear velocity. |
| Applicable Media | - Water - Oil (Mineral Oil, Synthetic Oil) - Alkaline Solutions (pH 8 - 14) - Acidic Solutions (pH 2 - 6) |
Suitable for a variety of common media in industrial applications. It can handle both aqueous and oil-based substances, as well as certain acidic and alkaline solutions within the specified pH ranges. |
| Installation and Maintenance | ||
| Installation Method | Axial Installation | The seal should be installed axially following the standard installation procedures. Precise alignment and proper handling during installation are crucial to ensure its normal operation. |
| Installation Torque | 20 - 30 N·m | Applying the appropriate installation torque is necessary to firmly secure the seal in place without causing damage to its components. |
| Maintenance Cycle | Check every 4000 operating hours | Regular inspections are required to monitor the wear condition of the seal, check for any signs of leakage, and ensure its performance remains optimal. |
| Storage Conditions | Store in a dry, dust-free environment at room temperature, away from direct sunlight and strong electromagnetic fields | Proper storage conditions can prevent the seal from being damaged by environmental factors, such as moisture, dust, and electromagnetic interference, and help maintain its original performance. |
| Quality and Certification | ||
| Service Life | Approximately 2 - 4 years under normal working conditions | With proper operation and maintenance, the seal can provide reliable sealing for this period, reducing the frequency of replacement and maintenance costs. |
| Leakage Rate | ≤0.05 mL/h | A very low leakage rate is achieved, which meets the strict requirements for environmental protection and system safety in industrial applications. |
| Certification Standards | ISO 9001, ISO 14001 | The seal complies with international quality management system (ISO 9001) and environmental management system (ISO 14001) standards, ensuring its quality and environmental friendliness. |
| Other Characteristics | ||
| Vibration Resistance | Can withstand vibrations with an amplitude of 0.3 - 0.8 mm at frequencies of 10 - 60 Hz | In industrial environments where vibrations are common, the seal can maintain its sealing performance and structural integrity within this vibration range. |
| Self-lubricating Property | The seal surfaces have a self-lubricating coating | This self-lubricating feature reduces friction between the sealing surfaces, prolonging the service life of the seal and improving its overall efficiency. |
