First, import glyd ring
Glyd ring consists of a O type rubber ring and a Teflon ring combination, the material is PTFE + NBR, special case of rubber elastomer NBR using nitrile rubber and fluorine rubber FKM. It can be divided into the hole with glyd ring and shaft with glyd ring, but the sealing effect is the same, the initial contact by deformation itself on the sealing surface to produce higher stress, prevent leakage of liquid pressure. The work of the hydraulic cylinder, the pressure of liquid by O ring elastic deformation was the maximum extrusion square ring, ring to import
The additional contact stress, which is higher than that of the sealing surface, increases with the increase of the pressure of the liquid, and together with the initial contact stress, prevents the leakage of the pressure liquid.
Two, glyd ring imported raw materials and main product categories
100% imported raw materials - the United States DuPont, Daikin, Germany LANXESS and other well-known companies to provide. High quality raw materials to ensure the sealing performance of the product. Taiwan Asahi Meike XOK sealing technology is dedicated to providing first-class imported seal of the company.
Main products:
A, O ring: a variety of materials of rubber O ring, mainly NBR, HNBR, FKM/VITON, EPDM, FFKM, SIL, PU, CR, PTFE etc.;
B, ED ring, star ring, rubber gasket, rubber ball, flat ring, combination washer, pneumatic seals and non-standard pieces of rubber parts;
C, cylinder: spot with TC skeleton oil seal oil seal, the other also has production, such as Y - ring, U - ring, V composite, stepseal, glyd ring and a dustproof ring seal, etc.;
Three, the import of glyd ring material specifications
NBR Ding Qing, FKM fluorine plastic, EPDM, SIL, PU, HNBR and other materials in the O type circle use note
O type ring is a widely used seal in industrial seal. Widely used in automobiles, sanitary ware, valve, machinery, food, medicine and so on. With high and low temperature resistance, oil resistance, ozone resistance, chemical resistance, cold resistance, chemical solvents, especially acid, aliphatic hydrocarbons, aromatic hydrocarbons and oils effect. However, if you do not pay attention to the use of good things, but also not the product's use efficiency.
1) O ring size is matched with the groove size, size is not suitable, can not use strong installation;
2) after the replacement, the old sealing ring can not be reused;
3) more than the service life of the O-ring to timely check replacement, not extension;
4) to replace the sealing ring, to strictly check the cleanliness of the groove in a timely manner and clean up;
5) to ensure the correct direction and in the installation process to protect lips from being damaged;
6) the replacement process according to the operating procedures.
Four, O type ring and other rubber seal parts purchase inspection procedures
O type of rubber products in the inquiry, ordering, delivery, receiving, using a series of processes, including the receiving part is also a very important part. It is actually the product in use before the corresponding checks. Here, Taiwan Asahi Meike seal XOK, suggestions from the following aspects:
1/ visual packaging is damaged, so as not to damage the sealing ring;
Check the 2/ agreement marked the sealing ring on the packaging material size, hardness, quantity and color and sales list;
3/ inspection seal is burr, bad bad phenomenon flash, convex and concave point and breakage etc.;
4/ check the number: if for large size, the number is not much, can be used in the form of points; if the small size, and the number is more, recommend the use of electronic scales weighing the nuclear to check the number of each package of the sealing ring;
5/ dimensions and tolerances confirmed: can use vernier caliper to measure the size of the sealing ring, in the form of sampling. Sampling rules and suggestions: the number of 500~1000, sampling 5%; the number of 1000~5000, sampling 3%; the number of 5000~10000, sampling 2%; the number of 10000, sampling 1%.
Or if you have any questions, you need to contact the supplier timely. Our company will glyd ring extended to Beijing, Shanghai, Tianjin and other parts of the country, and then generally around the world. Have good electrical insulation
