Q:What's the function of the sealing ring?: Composition of mechanical sealMechanical seals are mainly composed of the following four components. 1. Main seals: moving ring and stationary ring. 2. Auxiliary sealing parts: sealing ring. 3, pressing parts: spring, push ring. 4, transmission parts: play skip and key or fixed screw.

Q:Mechanical seals do not refuel, can not?: If the sealing ring, then choose ethylene propylene rubber as auxiliary seals. Do not connect with mineral oils or fats. Other lubrication and other things are to reduce friction, good installation is not easy to damage the sealing ring

Q:How can the tapered roller bearings be sealed?: At the same time, we should pay attention to the proper use of seals, can bring great benefits; improper use of seals, the effect is not great. For example, the contact seal seal under high speed heating and rapid wear and loss of seal, wear products and pollution of SKF tapered roller bearing; non contact seal in the seal on both sides of a differential pressure (pressure or pressure), dust or as oil sealing effect will become worse.

Q:What kind of seal is the dust sealing ring?: The dust ring is mainly used in hydraulic piston rod above the start, it is the role of the piston cylinder outside the dust to clear, avoid some particles inside the cylinder liquid and other contaminants penetrating sealing, improve sealing performance.

Q:What's the seal water? What about the water seal?: When the loss of seal water, to make the high pressure water pump inside through the pump shaft and the seal gap between the leakage, resulting in a large number of refrigerant loss; the water temperature of the high temperature at the same time will pass through the bearing shaft and the pump body of the metal, the bearing temperature rise, which can even make the bearing burned; high speed bearing the rotation and seal between the gap is very small, when the loss of sealing water, water film here is destroyed, and the shaft seal is likely to increase the friction, the vibration of the feed pump, which will cause equipment damage and outage.The function of water seal trough is to maintain the tightness of the lower part of the furnace and to prevent the air from leaking into the air.

Q:The material of the seal must be compatible with the medium in contact with it. Why? What is compatibility? Thank you: For example, three Yuan rubber sealing material is good, can withstand a certain corrosive acid, so it can be used to seal the acidic decomposition medium such as high voltage gas insulated SF6, but if used to seal the aviation hydraulic oil will fail because of three EPDM not resistant to oil, then we must choose nitrile rubber.

Q:What is the sealing principle of O type sealing ring?: O rubber ring seal is called O ring, it is a kind of rubber ring whose cross section shape is round. The O sealing ring is the most widely used seal in hydraulic and pneumatic systems

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 is the operation of the seal company sulfur chemical?What is the specific work? Is there any danger and harm?: Operator vulcanizing machine is the production of sealed products, the general operation of the vulcanizing machine, with the production of mold. The danger is that rubber products will generally have some taste, the body is not very good,

Q:What are the mechanical equipments for producing seals?: For mechanical seal words: lathe, grinding machine, drilling machine, polishing machine, ultrasonic cleaning machine, if the sealing material of their own production, it also need silicon carbide furnace, graphite machine, rubber vulcanizing machine, rubber machine etc.
