• 1. Do not force installation

  Some seals are placed in groove-shaped stuffing boxes. At this time, they need to be installed tightly. The construction should not be rough or brutal. Forcibly inserting them with large movements will inevitably destroy the original prefabricated structure of the seals. This is just like breaking the precast concrete and filling it into the required parts, which will inevitably lead to disaster.This type of seal must be installed very carefully and carefully, and the insertion must be done step by step. For example, like a rubber seal ring, this kind of sealing material is relatively soft. If it is not put in place, there will be no problem with forced installation, but the sealing effect will mainly be catastrophic.

• 2. Do not damage the sealing surface or sealing line on the surface of the seal.

  flatsealThe sealing performance of the component relies on the upper and lower end faces; the sealing performance of the hydraulic seal relies on the lip line matching the hole or shaft. These parts are made of special materials that are susceptible to damage such as graphite, rubber, plastic, and fiber that are soft and resilient and are temperature-resistant, corrosion-resistant, and aging-resistant. Therefore, special protection and care are required during transportation, installation, and storage. Once damaged, the sealing part will often be left with great hidden dangers.If the sealing surface is damaged and not regulated properly, it will cause uneven stress, which may cause leakage and poor sealing.

• 3、sealPay attention to balance and symmetry when installing parts

  Place the seal in a position that just touches the effective sealing surface (or lip line).After the system is put into use, further observation and follow-up work of tightening the seals are required to prevent collapse caused by micro-leakage due to changes in working conditions (such as pressurization) during the operation of the system.Therefore balance, symmetry helps reduce the presence of poor seals

After installing the seals, some parts need to test the sealing performance of the product, such as waterproof cameras, which generally use rubber sealing rings.Then, due to some problems with the material of the sealing ring or the installation position, etc., it may cause the camera to have poor sealing, resulting in the product not being waterproof.Therefore, it is necessary to detect the sealing of the camera to provide a basis for waterproofing the camera, because as long as the sealing is good, it will definitely be waterproof.

Therefore, products with seals installed or places that need to be sealed must undergo sealing tests to screen out unsealed or poorly sealed products and improve product quality.

The method of testing the seal is the traditional soaking in water method.However, with the development and growth of air leak detectors, the traditional method of soaking in water has lost its meaning.

Shenzhen Hairuisairleak detector, many years of testing experience, can be customized according to different requirementsSeal detectionplan.For example, for speaker seal testing, we can make a relatively sealed tooling based on the shape of the speaker, then put the speaker in, inflate the tooling, and then test the air pressure changes in the tooling. Based on the changes in air pressure, we can get the leakage amount, and based on the leakage amount, we can get the sealing performance.Waterproof IP rating
