|
Type
|
Multi-spring balanced mechanical seal
|
|
Size
|
22 mm (shaft diameter)
|
|
Application
|
Suitable for general industrial pumps, reactors, and mixers in chemical, pharmaceutical, and food processing industries
|
|
Sealing Principle
|
Face-to-face contact of two precision - ground sealing rings to prevent fluid leakage
|
|
Sealing Face Material
|
One face: Tungsten Carbide (WC), hardness: 1300 - 1500 HV; Other face: Carbon Graphite, density: 1.8 - 2.2 g/cm³
|
|
Spring Material
|
Stainless Steel 316, yield strength: ≥ 205 MPa, tensile strength: ≥ 520 MPa
|
|
O - Ring Material
|
A high - performance elastomer, Shore A hardness: 70 - 80, tensile strength: ≥ 10 MPa, elongation at break: ≥ 300%
|
|
Operating Pressure
|
Maximum static pressure: 1.6 MPa; Maximum dynamic pressure: 1.2 MPa
|
|
Operating Temperature
|
-20°C to 180°C
|
|
Rotational Speed
|
Maximum allowable speed: 2800 rpm
|
|
Axial Length
|
45 mm
|
|
Radial Clearance
|
0.05 - 0.1 mm
|
|
Face Flatness
|
≤ 0.0009 mm
|
|
Face Roughness
|
Sealing face of WC: Ra ≤ 0.2 μm; Sealing face of carbon graphite: Ra ≤ 0.8 μm
|
|
Torque
|
Starting torque: ≤ 1.5 N·m; Running torque: ≤ 0.8 N·m
|
|
Fluid Compatibility
|
Compatible with most non - abrasive and non - corrosive fluids, such as water, oils, and some organic solvents. For highly corrosive or abrasive fluids, additional material selection and protection measures are required
|
|
Installation Tolerance
|
Shaft runout: ≤ 0.05 mm; Housing bore runout: ≤ 0.08 mm
|
|
Service Life
|
Under normal operating conditions, the service life is ≥ 8000 hours
|
|
Weight
|
Approximately 0.5 kg
|
|
Lubrication Requirement
|
Self - lubricating due to the properties of the carbon graphite sealing face, but for some high - temperature or high - speed applications, additional lubrication may be beneficial
|
|
Assembly Instructions
|
1. Ensure all components are clean and free of debris. 2. Install the spring assembly onto the shaft first, followed by the O - ring and then the sealing faces. 3. Align the housing carefully to avoid misalignment that could damage the sealing faces. 4. Tighten the bolts evenly to a torque of 8 - 10 N·m
|
|
Maintenance Tips
|
1. Regularly check for signs of leakage. 2. Inspect the sealing faces for wear and damage during maintenance intervals. 3. Replace the O - ring if there are signs of aging or deformation. 4. Clean the mechanical seal thoroughly before reinstallation after disassembly
|
|
Performance Guarantee
|
1. Guaranteed leakage rate ≤ 5 ml/h under normal operating conditions. 2. The mechanical seal will maintain its performance within the specified parameters for at least 12 months from the date of commissioning
