Description
Technical field
The present invention relates to Reciprocting piston compressor, specifically a kind of anhydrous cooling air cylinder structure.
Background technique
In modern industry, with the development and utilization of natural gas, associated gas, shale gas etc., high revolving speed reciprocating compression
Machine has been more and more widely used, and in order to meet the requirement of compressor normal work, increases in the cylinder engine of compressor
Water cavity structure and water flowing cooling, to be cooled down to cylinder.Cylinder increases water cavity structure, can bring many disadvantages.Before casting
Phase is influenced by structure, is also easy to produce casting flaw, and leak, which occurs, for cylinder water cavity internally influences technique gas medium purity and stability,
Externally cylinder body is caused to corrode, reduces the intensity of cylinder, significantly increase security risk.While water flowing is cooling, increase
The subsidiary pipeline and relevant device of water circuit system, the space occupied for both having increased equipment also increase operating cost.
Cylinder is provided with the water cavity of package cylinder wall in existing structure, and entery and delivery port is arranged, and cooling water is from water inlet stream
Enter, flowed out from water outlet, forms water circulation system.
Existing structure is also easy to produce casting flaw the disadvantage is that the cylinder with water cavity structure is influenced in casting process by structure；
There are leak risks for cylinder water cavity, once leak, internally influences technique gas medium and even liquid hammer is caused to lead to cylinder rupture；Water flowing
While cooling, a set of cooling water equipment is increased, maintenance content, the space occupied of compressor set is increased, especially increases
Unit purchase cost and operating cost, reduce economic benefit.
Summary of the invention
The object of the present invention is to provide a kind of air cylinder structures of anhydrous cooling, instead of cylinder water cavity structure or single wall knot
Structure cancels compressor set cylinder cooling water system, air cylinder structure strong applicability.
In order to achieve the above objectives, the technical solution adopted by the present invention are as follows: a kind of anhydrous cooling air cylinder structure, including cylinder body and
Cylinder wall is characterized in that: being provided with air inlet above cylinder body, several air inlets are provided between air inlet and cylinder wall
Chamber is provided with reinforcing rib between adjacent inlet chamber, and air cavity wall is provided on the outside of inlet chamber, and air cavity wall occupies the outer of entire cylinder body
Circle, inlet chamber lower section are provided with discharge chamber relative to cylinder body central axes direction symmetric position, and air inlet lower section is relative in cylinder body
Axis direction symmetric position is provided with exhaust outlet.
The invention has the advantages and beneficial effects that: cancel the cooling water system of water cavity structure and cylinder, expands air cavity appearance
Product makes air cavity wall surround entire cylinder, makes the greater area of package cylinder wall of low temperature air inlet air-flow, increases distinctive reinforcing rib and protects
The intensity of cylinder body is demonstrate,proved, structure is simple, convenient for casting, reduces cost；Without equipment such as attached cooling water pipelines, reduces equipment and throw
Enter and improve space utilization rate, reduces buying, operation and maintenance cost.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is A-A sectional view in Fig. 1；
Fig. 3 is B-B sectional view in Fig. 1；
Appended drawing reference is as follows:
1, air inlet 2, inlet chamber 3, reinforcing rib 4, air cavity wall 5, cylinder wall 6, discharge chamber 7, exhaust outlet.
Specific embodiment
As shown in Figure 1-3, the present invention relates to a kind of anhydrous cooling air cylinder structure, including cylinder body and cylinder wall 5, in which: cylinder
It is provided with air inlet 1 above body, several inlet chambers 2 are provided between air inlet and cylinder wall, are arranged between adjacent inlet chamber
There is reinforcing rib 3, air cavity wall 4 is provided on the outside of inlet chamber, air cavity wall occupies the outer circle of entire cylinder body, and inlet chamber lower section is relative to cylinder
Body central axes direction symmetric position is provided with discharge chamber 6, is arranged below air inlet relative to cylinder body central axes direction symmetric position
There is exhaust outlet 7.
Technical problem solved by the present invention is Reciprocting piston compressor is to move back and forth to make gas in cylinder by piston
Body boosting.When piston moves back and forth in cylinder, piston packing ring and cylinder wall generate frictional heat.Frictional heat is solved at present
Method is to take away frictional heat by being constantly passed through cooling water into cylinder water cavity.Cylinder increase with water cavity structure is produced into
Originally and it is also easy to produce casting flaw.To be passed through cooling water to cylinder, compressor set needs to be equipped with a set of cooling water system, the system packet
Include water pump, pump motor, water cooler, water tank, several valves and pipeline etc..The cooling system increases the maintenance of compressor set
Content, space occupied especially increase unit purchase cost and operating cost, reduce economic benefit.To solve above-mentioned technology
Problem, the present invention use anhydrous cooled air cylinder structure.
The anhydrous cooling cylinder that the present invention protects cancels the water cavity structure of regular cyclical product, including water cavity wall, disengaging
The structures such as the mouth of a river change mould structure, cast the cylinder body of new model, air cavity wall is increased to entire by original small part structure
The outer circle of cylinder body increases the volume of inlet chamber, and increases reinforcing rib between the inside wall of cylinder among two air inlets, guarantees entire cylinder
The intensity of body is ultimately formed with the structure of air cavity package cylinder inner wall.When the compressor is operated, the charge air flow of low temperature first from
Cylinder air inlet enters inlet chamber, and is full of inlet chamber, and the charge air flow of low temperature wraps up cylinder inner wall, exchanges heat, by gas
The frictional heat of casing wall is conducted to the charge air flow of low temperature, i.e., the charge air flow of low temperature is instead of cooling water.In gas cylinder working condition
Under, it is neither water-cooled, can also reach the operating condition for having the cooling cylinder of water.
