The important thing to do 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 prevent dust from falling on the surface of the seal during installation. How to properly place when a valve assembly is installed to avoid crushing seals, clean hydraulic media, etc.
Specifically, you should pay attention 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 the shaft. These parts are both soft and Rich in elasticity, corrosion-resistant, anti-aging graphite, rubber, fiber, and other special materials that are vulnerable to damage, so it is necessary to give special protection and care during handling, installation and storage. Will leave a big hidden danger to the sealing part;
2, can not be forced to install some seals are placed in the trough-like stuffing box, then need to be tightly installed, construction can not be rough, barbaric, forced to load a large force will inevitably destroy the original prefabricated structure of the seal, this is like Breaking the precast concrete and filling it into the desired part will inevitably lead to disaster. The installation of such seals must be very careful and careful, and the embedding must be carried out step by step;
3. When installing, pay attention to balance and symmetry to place the seal at the position just close to the effective sealing surface (or lip line). After the hard seal ball valve is opened for use, further observation and tightening of the seals are required to prevent the micro-leakage from being broken due to changes in working conditions (such as pressurization) during system operation.
When the seal is used a lot of time, after the completion of the process, even if the equipment has passed the test, it will still be a problem after being sent to the user for a period of time. Under normal circumstances, it may be caused by improper use, for example, the oil temperature is too high. If the seal is burnt, check whether the cooling system is operating normally. The surface of the rod is worn and leaks. Check the hydraulic oil for debris and whether the filter is invalid. From the above, it can be seen that even if the user is willing to pay a high price to purchase high-quality seals, it must be controlled and monitored in all aspects, in order to ensure that the investment will not be in vain, choose a professional seal manufacturer, comprehensive investigation and analysis, It is very necessary.
