Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirement.

②How to guarantee the quality of the products？

We have established the international advanced quality management system every link from raw material to final product we have strict quality test; We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q:How to choose the sealing ring according to the shaft?: The selection of the sealing ring is mainly based on the service temperature, hardness and working medium of the material, as well as the size of the installation shaft and the form of sealing.

Q:Design of sealing ring, groove and bottom fillet of sealing ring: The rounded corners at the bottom of the groove are mainly designed to avoid stress concentration. The value of fillet radius, dynamic sealing groove desirable R=0.3~1mm, static sealing groove, it is recommended that its O ring section diameter of half, that is R=d/2

Q:Classification of the use of seals: The seal according to the shape and material type, sealing structure, sealing mechanism, classification of seal for packing into the packing cavity after the gland axial compression on it (see figure 29.5-9), when the filler and relative motion, because the plastic filler to produce a radial force, and close contact with the axis. At the same time, the lubricant impregnated in the packing is extruded and an oil film is formed between the contact surfaces. Because the contact state is not uniform, the contact parts will appear the boundary lubrication condition, known as the "bearing effect"; the concave without contact to form a small oil tank, oil film thickness, contact and non-contact parts of an irregular maze, preventing the liquid leakage flow this effect, called "labyrinth effect". This is the mechanism of packing seal. Obviously, the good seal is to maintain the "bearing effect" and "labyrinth effect"". That is to say, to maintain good lubrication and proper compression. If the lubrication is bad or pressed too tight, the oil film will be interrupted, resulting in dry friction between the packing and shaft, and finally lead to burning shaft and serious wear and tear. To this end, often on the packing pressing degree of adjustment, so as to fill in the lubricant after running for a period of time loss, and then squeezed out some lubricant, pressing force relaxation while compensating for volume changes caused by filling.

Q:You want to ask knowledgeable friends. I want to do at home produced small seal factory. The former is to buy it do seal butterfly valve. Now they want to engage in their own ring. Do not know what equipment and capital equipment. Then buy new and used funds is how much. Is the production of multi-level sealing ring and PTFE. What materials should I indebted forever: These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!

Q:Mechanical seal national standards, where is it? Who can give me a look or write related websites, I urgently needed mechanical seal national standard, thank you.: activeGB/T 10922-200655 degrees unsealed pipe thread gauge, national quality supervision, inspection and quarantine. Current 2006-08-01GB 11023-1989 high voltage switchgear six sulfur hexafluoride gas sealing test method Ministry of machinery electronics industry 1990-01-01

Q:What is the life span of all kinds of rubber seals?: Your question is a false proposition, the rubber seal life is related to material and working conditions, rubber is a lot of weight, there are fluorine rubber, silicone rubber and so on,

Q:What is the maximum resistance to the seal in the hydraulic system currently being produced?: Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).

Q:How are ceramic and metal sealed joint?: If it is static sealAxial, O ring or flat gasket can be used; radial O ring can be used.If it is dynamic seal, in addition to radial seal, but also consider whether the need for axial dust ring.The end face seal has a special sealing ring, and the lip is contacted with the ceramic surface.For reciprocating motion, a combination of O rings or other cross sections can be used.

Q:Why can't polyurethane seal be used as hydraulic oil with water glycol?: Polyurethane, known as polyurethane, is a general term for macromolecular compounds containing repetitive urethane groups on the main chain. It is made up of organic diisocyanate or polyisocyanate with two hydroxyl or polyhydroxy compounds. The polyurethane material, very versatile and can replace the rubber, plastic, nylon, used in airport, hotel, building materials, automobile plant, coal plant, cement plant, Premium Apartment House, villas, garden landscaping, stone art park, etc..

Q:What are static seals and dynamic seals?: For example, the hydraulic cylinder seals in the cylinder and the cylinder to seal, but the wall in the back and forth movement, which is the dynamic seal
