Background technology
Now using the air-cooled air cylinder structure of tradition more than majority piston compressor hiigh pressure stage cylinder, by outside cylinder
Directly process cooling fins to cool down cylinder, make cylinder operating temperature less than regulation under natural ventilating status
So as to ensure the normal work of piston ring, support ring and associated seal.Its concrete structure is main by cylinder cap 1, cylinder as shown in Figure 1
2, cylinder sleeve 3, air cooling fin 4 and lower locating flange 5 are constituted, the mode of cylinder head 2, air cooling fin 4, lower locating flange 5 with welding
Link together composition cylinder block 6, reinstalls cylinder sleeve 3 after cylinder block 6 is processed, and cylinder cap 1 is then anchored on by four bolts
In cylinder block 6.
At present, this structure is natural cooling air flow temperature that is relatively slow and can not controlling cooling medium, air and cylinder
Heat exchanger effectiveness relatively low, still suffer from certain problem in use：
1st, (both operating temperature in cylinder when this grade of cylinder compression ratio of compressor is higher or compressed media adiabatic exponent is larger
Higher), the high temperature of casing wall cannot be taken away in time, so as to piston ring is under HTHP situation for a long time, be made without oil machine plastic movable
The plug ring life-span is greatly lowered, and piston ring is changed frequently, and compressor operating cost up, economy decline.
2nd, because cylinder cooling fins are exposed at cylinder surface, in compressor operating, its surface temperature is higher, easily to scene
Staff causes to scald.
Content of the invention
The utility model provides a kind of air blast cooling cylinder, it is therefore an objective to solve prior art problem, there is provided a kind of work peace
Entirely, heat exchange efficiency is high, cooling is fast, the air blast cooling cylinder of long service life.
The technical solution adopted in the utility model：
A kind of air blast cooling cylinder, with cylinder cap, cylinder head, fin, cylinder sleeve and lower locating flange, cylinder head, fin and lower fixed
Position flange is composed of a fixed connection cylinder body, is arranged with cylinder sleeve in cylinder body, and cylinder cap is then fixedly connected with cylinder body by bolt, and its feature exists
In：Shown fin is flow-inclining fin, and flow-inclining fin is evenly distributed along cylinder body outer helical, is arranged with kuppe outside flow-inclining fin,
The air-cooled chamber of spiral is surrounded between kuppe and flow-inclining fin, air-cooled chamber is connected with air inlet and air outlet, air inlet is located at and leads
The bottom connection air-intake device of stream cover, cylinder head and cylinder cap are respectively equipped with the air exhaust passage and cylinder of air exhaust passage, air-cooled chamber and cylinder head
The air exhaust passage of lid is sequentially communicated, and cylinder cap is provided with air outlet, and the air exhaust passage of cylinder cap is connected with air outlet.
The cylinder cap top is provided with the lid that confluxes, and air outlet is located at the lid that confluxes, and the air exhaust passage of cylinder cap is connected with air outlet.
The adjacent two panels fin of the flow-inclining fin is different in size, and cooling air-flow realizes baffling in air-cooled chamber.
Elevated pressure plenum equipment is provided between air inlet and air-intake device.
The beneficial effects of the utility model：Cooling (heat exchange) efficiency of cylinder is drastically increased, wall temperature reduces,
It is improved without the oil machine piston ring life-span, user's operating cost reduces, economic benefit increases, while kuppe can also be good
Protection staff avoids the unexpected injury that the cylinder body for touching high temperature in the course of the work brings.

Specific embodiment：
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of air blast cooling cylinder as shown in Figure 2, with cylinder cap 7, cylinder head 8, fin 9, cylinder sleeve 10 and lower locating flange 11,
Cylinder head 8, fin 9 and lower locating flange 11 are composed of a fixed connection cylinder body 12, are arranged with cylinder sleeve 10 in cylinder body 12, and cylinder cap 7 then passes through
Bolt is fixedly connected with cylinder body 12, and shown fin 9 is flow-inclining fin, and flow-inclining fin 9 is evenly distributed along 12 outer helical of cylinder body, folding
Kuppe 13 is arranged with outside stream fin 9, the air-cooled chamber 14 of spiral, the baffling wing between kuppe 13 and flow-inclining fin 9, is surrounded
The adjacent two panels fin of piece 9 different in size, cooling air-flow realizes baffling in air-cooled chamber 14, air-cooled chamber 14 and air inlet 15 and
