Is The Spark Generated By The Friction Of The Rotating Shaft The Cause Of The Sealing Ring?

Nov 26, 2021

Is the spark from the friction of the rotating shaft the cause of the sealing ring? Yes, not choosing the right material can also lead to this situation. For example, if the iron seal ring rubs against the shaft during work, sparks will occur, which will affect the production efficiency of the machine.


PTFE seals can make up for the above shortcomings: PTFE seals is mainly made of PTFE material, which is durable and has good comprehensive mechanical properties. It has good abrasion resistance and low friction coefficient. When the load is sliding, the friction coefficient changes only between 0.05 and 0.15. Under high load, it has excellent wear resistance. Under a certain load, it has multiple advantages of wear resistance and non-sticking.


High temperature resistance up to 260 ℃, good corrosion resistance, PTFE sealing ring is almost not corroded by chemicals, and can withstand all strong acids except molten salty metals, fluorinated media and sodium hydroxide higher than 300 ℃. The role of oxidizer, reducing agent and various organic solvents can protect the accessories from any kind of chemical corrosion.


A Hubei Machinery Technology Co., Ltd. mainly produces equipment required for the chemical industry: biodiesel equipment, reaction tanks, reactors, stainless steel reactors, outer coil half-tube heating stainless steel reactors, multi-functional dispersion reactors, steam heating heat transfer oil Circulating heating reactors, emulsifiers, stirring tanks, heat exchangers, storage tanks, etc. and other mechanical equipment such as food, chemicals, coatings, inks, medicines, and cosmetics.


PTFE seals is needed in the production process. Find our company (Dongsheng Sealing) through online channels. Customer requirements: For the rotating shaft, since the shaft is made of S30408 material, the seal ring cannot be made of iron, because the friction between iron and iron will produce sparks. The shaft diameter is 120 and 130 two specifications, pressure -0.09mpa, speed: 1450 rpm, temperature: 145°C, medium: flammable, used above the stirring shaft.


According to customer needs, our company helped customers select a type of PTFE sealing ring, which meets the customer's mechanical equipment requirements in all aspects. This cooperation is very pleasant. If this happens to your machinery and equipment, welcome to consult Dongsheng Sealing.
