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: What is the life span of all kinds of rubber seals?
- Different working conditions, the degree of wear on the seal is different, such as some seals will contact strong acid, strong alkali substances, and some have to do high-frequency reciprocating friction,
- Q: What is the operation of the seal company sulfur chemical?What is the specific work? Is there any danger and harm?
- Then there is vulcanizing machine is generally heating, pressure equipment, vulcanizing board temperature is higher, easy to scald. So be careful in operation
- Q: 500 degree high temperature rubber sealing strip
- High temperature resistant seal PTFE (plastic) - (195 ~ 250 DEG C) can be used for a long time.
- Q: What is the function of the seal?
- It is easy to cause the oil leakage, affecting the normal work of the machine, 75 A caused by burn bearings, broken gear, shaft break or other serious fault
- Q: Requirements for storage of rubber seals
- Keep it in the shade, not in the damp place. It's best to wrap it up. Don't be exposed to the sun
- Q: What kind of performance requirements should the rubber seals meet?
- Hygienic propertyRubber products is the basic appearance of bread wrapped in a layer of rubber material, the appearance is basically the same, but the internal quality will have great differences, in the process of sealing performance using rubber seal strengthening of certain products, we must avoid pollution problems, so in the use of rubber sealing, material requirements, must be used non-toxic materials and prohibited the use of recycled rubber seals, and suitable for drinking machine and other products on the GB/T17219-1998 must pass "drinking water distribution equipment and protective materials safety evaluation standards" or BS6920:2000 "through the test of non - metallic products non-toxic effects on water quality for inspection of the body contact".Above is the performance requirements for rubber experts to introduce you to the Luo Geng mechanical seals are used to seal materials, there are various types, in use to different products, we need to use the seal will be different, but most of the time to see in addition to seal the dimensions, we see the seal of the materials used, whether has the properties we need, so as to determine whether the rubber seal products.
- Q: What is the international requirement for the temperature of the seal in the hydraulic cylinder?
- X ring, rubber ring, rubber ball, Pu seal, seal, pipe joints seals, rubber gaskets and rubber parts. All imported raw materials.
- Q: The difference between piston seal and piston rod seal
- Piston rod seal refers to the seal between the piston rod and the cylinder head. If the seal is not good, it will leak oil, and the sealing groove is opened on the hole.
- Q: What kind of material seals can withstand ammonia, -40 degrees to 200 degrees?
- PTFE seals can withstand ammonia, -40 degrees to 200 degrees.Advantages of polytetrafluoroethylene:1, PTFE is a fluorocarbon chemicals chemical resistance and excellent resistance to high temperature, even when exposed in the air will not deteriorate, can be used for a long time in the temperature range of -200~250.
- Q: What are the storage conditions for seals?
- First of all, the pressure is an important factor affecting the quality of seals, the pressure level, the length of the pressure cycle cycle, the seal damage (such as extrusion) have a great impact. The higher the pressure, the greater the influence of other factors on the performance of the seal, such as temperature, speed, the material of the seal, the clearance between the piston and the cylinder, the clearance between the piston and the cylinder head.Another is the temperature and friction, it is difficult to describe the maximum use temperature and minimum use temperature of a sealing material, because it is the result of a series of factors. The piston and piston rod have different operating temperatures, so we should choose them differently. Another is the seal product surface roughness, surface characteristics, pressure, medium, temperature, sealing materials, seals type and speed of movement, these are the factors affecting the seal.The last is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and the piston rod have a great influence on the life of the seal. Surface characteristics are defined by the values of surface roughness RA. RA is the arithmetic mean of the shape of the surface deviating from the absolute value of the center line. However, these values do not fully indicate the effect of surface conditions on the seals, because even under the same roughness, different surface shape features can cause wear of seals to varying degrees of seal.
