3. Measurement and Selection

Accurate measurement is critical for selecting the correct O-ring size to ensure an effective seal. An improperly sized O-ring can lead to leaks or premature failure.

3.1. Measuring O-Ring Dimensions

• For O-rings with an Inner Diameter (ID) of 1-30mm, measurement can be performed using a pin gauge.
• For O-rings with an ID of 30-60mm, an O-ring measuring ruler can be used. The ID is calculated as Ld/π (where Ld is the measured length).
• For O-rings with an ID of ≥60mm, use an O-ring measuring ruler or a soft ruler. The Outer Diameter (OD) is calculated as Ld/π.
• Ensure there is no deformation or gap during measurement to obtain accurate readings.

3.2. Материалдык шайкештик

Nitrile rubber is suitable for applications involving petroleum-based oils, hydraulic fluids, water, and alcohols. It is generally not recommended for use with brake fluids, ketones, or strong oxidizing agents. Always verify material compatibility with the specific fluids and environmental conditions of your application.

4. Орнотуу боюнча көрсөтмөлөр

Proper installation is crucial for the longevity and effectiveness of the O-ring seal.

1. Таза беттер: Ensure all sealing surfaces are clean, free from dirt, debris, and sharp edges that could damage the O-ring.
2. Майлоо: Lightly lubricate the O-ring with a compatible lubricant (e.g., silicone grease or the system fluid) before installation. This aids in seating and reduces friction during assembly, preventing twisting or pinching.
3. Туура отургуч: Carefully place the O-ring into its groove. Ensure it is not stretched excessively, twisted, or pinched during assembly. The O-ring should sit evenly within the groove.
4. Avoid Over-Compression: Do not over-tighten components, as this can lead to excessive compression of the O-ring, causing premature wear and failure.

5. Тиркемелер

These Nitrile Rubber O-Rings are versatile and widely used in various sealing applications due to their material properties and standard sizing. Common applications include:

• Басымдагы жуугучтар
• Чыпкалар
• Насостор

6.1. Техникалык тейлөө

Regular inspection of O-rings in critical applications can prevent failures. Look for signs of wear, cracking, hardening, softening, or swelling. Replace O-rings that show any signs of degradation or damage. Store unused O-rings in a cool, dry place away from direct sunlight and ozone-generating equipment to preserve their material integrity.

6.2. Troubleshooting Leaks

• агып кетүү: If a seal leaks, first check if the O-ring is correctly sized for the groove. An O-ring that is too small may not provide adequate compression, while one that is too large may be pinched or extruded.
• Зыян: Inspect the O-ring for cuts, nicks, or abrasions that could compromise the seal. Replace any damaged O-rings.
• Материалдык бузулуу: If the O-ring shows signs of chemical attack (swelling, shrinking, hardening, or softening), ensure the material is compatible with the fluid it is sealing.
• Туура эмес орнотуу: Re-check that the O-ring was not twisted or pinched during installation. Disassemble, inspect, and re-install if necessary, ensuring proper lubrication.
