According to information dated 09-Sept-2021, measuring a shaft seal involves specific steps focusing on its key components: the seal face, the spring, and the stationary seat. Following these steps helps determine crucial dimensions like shaft size and seal dimensions.
Steps for Measuring a Shaft Seal
Measuring a shaft seal precisely is essential for selecting the correct replacement. The process, as outlined in the reference, focuses on identifying the dimensions of the seal's primary parts.
Here are the steps involved:
-
Remove the seal face from the spring and assess its inside diameter.
- This measurement is critical as it directly determines the shaft or sleeve size the seal is designed to fit.
-
Next, determine the length of the spring once separated from the seal face.
- Measuring the spring length is another key step in assessing the seal's specifications, though the reference does not explicitly state what this measurement determines.
-
Measure the outside diameter, the inside diameter, and thickness of the stationary seat.
- The stationary seat is the part of the seal that remains fixed, usually in the pump housing. Measuring its outside diameter (OD), inside diameter (ID), and thickness provides the dimensions needed to ensure it fits correctly within its mounting location.
Summary of Key Measurements
To make it easier to understand the required measurements, here is a summary based on the provided reference:
| Component | Measurement(s) | Purpose (as per reference) |
|---|---|---|
| Seal Face | Inside Diameter (ID) | Determines Shaft/Sleeve Size |
| Spring | Length | Part of Seal Assessment |
| Stationary Seat | Outside Diameter (OD), Inside Diameter (ID), Thickness | Part of Seal Assessment |
By following these steps and obtaining these specific measurements, you can effectively measure a shaft seal according to this particular method dated 09-Sept-2021.
