Seal Installation and Use

by:ORK      2022-11-13
The most important thing when installing the gasket is to avoid damage to the seal. In addition to the proper finish, safe chamfering, deburring, and proper tools, how to avoid dust floating on the surface of the seal during installation, How to properly position to avoid crushing of seals, clean hydraulic media, etc. when installed such as valve assembly. Specific attention should be paid to the following points: 1. Do not damage the sealing surface of the seal surface or the sealing line. The sealing performance of the flat seal depends on the upper and lower end faces; the sealing performance of the hydraulic seal depends on the lip line associated with the hole or shaft. These parts are made of temperature-resistant, corrosion-resistant and aging-resistant graphite, rubber seals and fiber, which are both soft and resilient, and are easily damaged. Therefore, special protection is required during handling, installation and storage. And care, once damaged, it will often leave a lot of hidden dangers to the sealing part; 2. Do not install forcibly Some seals are placed in the grooved stuffing box, at this time, they need to be installed tightly, and the construction should not be rough, brutal, or move A large forcible installation is bound to destroy the original prefabricated structure of the seal, just like breaking the prefabricated concrete and filling it in the required position will inevitably lead to disaster. The installation of this type of seal must be very careful and careful, and the embedding must be carried out step by step; 3. Pay attention to balance and symmetry during installation. Place the seal at the position that just closes the effective sealing surface (or lip line). After the hard-sealed ball valve is put into use, it is necessary to do further observation and follow-up work to tighten the seals to prevent the collapse caused by micro-leakage due to changes in working conditions (such as pressurization) during the working process of the system. When the seals are used a lot, after the valve matching user completes the process, even if the equipment has passed the test, there will still be problems after it is delivered to the user for a period of time. In general, it may be caused by improper use, such as the oil temperature is too high. If the seal is burnt, it can be checked whether the cooling system is operating normally, the surface of the tie rod is worn and leaking, and whether there is debris in the hydraulic oil and whether the filter is invalid. It can be seen from the above situations that even if users are willing to pay a higher price to buy high-quality seals, they must be controlled and monitored in all aspects to ensure that the investment will not be wasted. is necessary.
