Description
Technical field
The invention belongs to graphite pressing pressure container manufacture field, and in particular to a kind of graphite pump of metal enhancing.
Background technology
Graphite is a kind of crystalline carbon, its chemical property torpescence, corrosion-resistant, is not reacted with acid, alkali etc..Because it has
The features such as two-dimensional structure and lubrication, high temperature resistant, stable chemical performance, long usage time, it is set to be processed to graphite valve and wide
It is general to be applied to oil, chemical industry, nuclear power industry.Graphite valve decay resistance is strong, and usage time length, maintenance cost is low, uses
The devices such as graphite valve, pump and pipeline, it will not be reacted when class I liquid I is corroded in conveying.At present, graphite lining valve is adding
In work, one layer of acid resistant adhesive mortar, then lining stone ink, or the side mechanically connected with graphite are mainly first served as a contrast inside device to be processed
Method, processing method is more complicated, does not apply to the processing of small parts.And the degree of adhesion of graphite lining and device inwall is not
Good, air-tightness also has much room for improvement, seriously corroded, and service life is shorter.
The content of the invention
The invention aims to solve in the prior art, graphite lining pump corrosion resistant performance is poor, the short difficulty of service life
Topic, and then a kind of manufacture method of the graphite pump of metal enhancing is provided.
The technical scheme is that：A kind of graphite pump with metal enhancing, including bent axle 1, graphite plunger 2, metal
Plunger rod 3, graphite cylinder 4, the cylinder body shell 5 of metal enhancing, graphite pump cover 6 and the graphite pump cover 7 of metal enhancing of enhancing, stone
Black plunger 2 is interior, graphite cylinder 4 is outer and graphite pump cover 6 is outer is manufactured by the method for casting metals, passes through machinery after casting again
Machine the manufacture of graphite pump.The inwall of graphite plunger 2, the outer wall of graphite cylinder 4, the outer wall of graphite pump cover 6 have multiple
Tongue and groove.
The present invention has the advantages that：The manufacture method of the present invention and prior art contrast, employ reverse
Thinking.Its first processing graphite cylinder body, graphite plunger and graphite pump cover again by the method for casting process cylinder body that metal strengthens and
The thinking of pump cover shell and metal enhancing post so that processing technology greatly simplifies, and is especially suitable for the large, medium and small type of manufacture and complexity
The processing of workpiece, make it have more preferable air-tightness, heavy antisepsis, pressure-bearing property and durability.
Brief description of the drawings
Fig. 1 is the structural representation of the graphite pump of metal enhancing of the present invention.
Each component names and label are as follows in apparatus of the present invention：Bent axle 1, graphite plunger 2, metal enhancing plunger rod 3,
Graphite cylinder 4, the cylinder body shell 5 of metal enhancing, graphite pump cover 6 and the graphite pump cover 7 of metal enhancing.
Embodiment
With reference to specific embodiment, the present invention will be further described：
Referring to Fig. 1, a kind of graphite pump with metal enhancing of the present invention, including bent axle 1, graphite plunger 2, metal increase
Strong plunger rod 3, graphite cylinder 4, the cylinder body shell 5 of metal enhancing, graphite pump cover 6 and the graphite pump cover 7 of metal enhancing, graphite
Plunger 2 is interior, graphite cylinder 4 is outer and graphite pump cover 6 is outer is manufactured by the method for casting metals, is added again by machinery after casting
Work completes the manufacture of graphite pump.The inwall of graphite plunger 2, the outer wall of graphite cylinder 4, the outer wall of graphite pump cover 6 have multiple recessed
Tongue.
The method for manufacturing the graphite pump of above-mentioned metal enhancing, comprises the following steps：
A the graphite pieces such as cylinder body) are prepared：Take graphite powder, pass it through glue mixing molding after, high-temperature roasting into the graphite
The graphite body that plunger 2 and graphite cylinder 4, the geomery of cylinder body shell 5 of metal enhancing match；
B mould and metal shell) are prepared：Graphite plunger 2 in above-mentioned steps, graphite cylinder 4 are used as and graphite pump cover 6
The outer internal model of mould, sand mo(u)ld is recycled to go out the cylinder body shell 5 of metal enhancing, gold as the external mold casting metals liquid cast of mould
Belong to the plunger rod 3 of enhancing and the graphite pump cover 7 of metal enhancing；
C the pump housing) is prepared：The cylinder body and metal shell that will be cast after hot melt, and being cooled and shaped, remove mould external mold it
Afterwards, the graphite pump that there is metal to strengthen is obtained through over mechanical processing and installation.
The sand casting that the present invention applies is widely used cast form.Just as the name indicates, exactly manufactured with sand
Mold.Sand mo(u)ld processing factory can be with casting large-scale part, and its is cheap, and can produce the part of various sizes, and equipment is thrown
Money is few, and raw material are easy to get and cheap.
And dexterously the internal model using graphite cylinder as mould, the external mold of graphite cylinder, graphite pump cover are interior to the present invention
Mould is used in combination with sand mo(u)ld so that graphite cylinder is combined together with the metal in close after hot melt, its heavy antisepsis and air-tightness
It is very good.
To sum up, manufacture method of the invention and prior art contrast, employ reverse thinking.Its first processing graphite
Post, cylinder body and pump cover, reprocess the thinking of metal shell and plunger so that processing technology greatly simplifies, and makes it have preferably
Air-tightness, heavy antisepsis, pressure-bearing property and durability.
The above is only presently preferred embodiments of the present invention, is not intended to limit embodiment of the present invention, and this area is general
Lead to central scope and spirit of the technical staff according to the present invention, can very easily carry out corresponding flexible or modification, therefore originally
The protection domain of invention should be defined by the protection domain required by claims.
