Abstract
The utility model relates to a brittle-rupture resistant graphite stationary seal ring used for a mechanical sealing. The brittle-rupture resistant graphite stationary seal ring used for the mechanical sealing is composed of metal, graphite and bonding materials. The metal is ferronickel, the graphite is fragment-shaped soft graphite, and the bonding materials can be organic bonding materials or other glue. The manufacturing process is evenly mixing the metal, the graphite and the bonding materials according to a regulated ratio and then placing the metal, the graphite and the bonding materials in a die to conduct pressing and molding. To enhance the strength of the brittle-rupture resistant graphite stationary seal ring used for the mechanical sealing, the pressed and formed graphite stationary seal ring can be placed in a high-temperature environment to be heated and solidified. The brittle-rupture resistant graphite stationary seal ring used for the mechanical sealing can be used as a stationary seal ring material for the mechanical sealing.
Description
Technical field
The utility model relates to a kind of mechanical seal graphite stationary ring of anti-embrittlement.
Background technique
At present, the material that generally is used for mechanical seal friction pair stationary ring mostly adopts graphite material.Graphite is that the widest friction pair group of mechanical seal industry Applicable scope is to material, has good self-lubricating property, friction factor is low, excellent anti-corrosion performance, heat-conducting property is excellent, and linear expansion coeffcient is low, group is to performance and heat resistance is good and characteristics such as easy processing, therefore, the scope of its application is extremely wide, and the quantity of application is very big.But the friction pair stationary ring made from graphite material but has a fatal weakness, and that is that mechanical strength is very low with regard to it, and is very fragile, very easily embrittlement and cracked under inhomogeneous pressurized condition.The MANUFACTURER of a lot of mechanical seals has identical personal cognition with the user, that is: the mechanical sealing static ring of graphite material manufacturing is in the transportation transport process, very easily in cargo handling process, be subjected to external force to cause stationary ring crackle, embrittlement or cracked, cause into waste product and can not use; Also have MANUFACTURER or user to install in the mechanical seal process also and can cause the cracked waste product that forms of stationary ring owing to undue force a little at assembling goods, cause waste and the leeway of finished product thus.Very headache always to this in the industry, and more effectively solution is not proposed so far.
Summary of the invention
The utility model proposes a kind of mechanical seal graphite stationary ring of anti-embrittlement.The mechanical seal of described anti-embrittlement is made up of metal, graphite and binder with graphite stationary ring.Described metal is iron-nickel alloy, and the linear expansion coeffcient of this metal alloy is: 0.5 * 10
-6, than regulation and the rotating ring of standard-required and the linear expansion coeffcient 4.5 * 10 of stationary ring
-6Much lower, satisfy usage requirement fully; Binder can be organic bonding glue or other glue classes.Its manufacturing process is graphite and the binder that iron-nickel alloy metal ring or tinsel, in accordance with regulations ratio are mixed, and is placed on compression moulding in the mould.In order to strengthen its intensity, the graphite stationary ring of compression moulding can also be put into high temperature and be heating and curing.The mechanical sealing static ring material made from described method, all advantages and the performance that have not only kept the graphite material stationary ring, what is more important, owing in manufacture process, ring-type or sheet or strip iron-nickel alloy are placed the central position of graphite stationary ring, strengthen the mechanical strength of graphite stationary ring effectively, fundamentally solved stationary ring that graphite material in the past makes very easily embrittlement and cracked problem.
The utility model is achieved through the following technical solutions for achieving the above object: a kind of mechanical seal graphite stationary ring of anti-embrittlement is characterized in that: the mechanical seal of described anti-embrittlement is made up of metal, graphite and binder with graphite stationary ring.Described metal is iron-nickel alloy; Binder can be organic bonding glue or other glue classes.Its manufacturing process is graphite and the binder that iron-nickel alloy metal ring or tinsel, in accordance with regulations ratio are mixed, and is placed on compression moulding in the mould.In order to strengthen its intensity, the graphite stationary ring of compression moulding can also be put into high temperature and be heating and curing.
This shows, in technique scheme of the present utility model, the graphite and the binder that in manufacture process, place the central position of graphite stationary ring, ratio in accordance with regulations to mix ring-type or sheet or strip iron-nickel alloy, be placed on compression moulding in the mould, and be aided with the technology that is heating and curing in the high temperature, strengthen the mechanical strength of graphite stationary ring effectively, fundamentally solved stationary ring that graphite material in the past makes very easily embrittlement and cracked problem.
