Abstract

The utility model discloses a quiet set of water -chilling plant of scroll compressor, cooling device adopts bolted connection with quiet dish, through gasket seal, heat transfer fin and sealing rubber pad piece vertically contacting form fan -shaped passageway on the quiet dish, reducing bend and dull and stereotyped straight tube and the water pipe adoption threaded connection of going up of circle, reducing bend trompil department adopts non -metallic material to seal, the diameter of drum is greater than the diameter of heat transfer fin place circle. Its advantage lies in: coolant is water, and low cost is easy, more heats can be taken away when the cooling water carries out the heat exchange, the energy consumption of compressor is favorable to reducing, the device that designs is the not subjected to pressure container, and the outer wall is thinner, the mobile energy requirement of cooling water is lighter than the mobile required energy of air.

Description

The quiet dish water-cooling apparatus of a kind of screw compressor

Technical field

The utility model relates to the heat exchange of the quiet dish outer surface of screw compressor, improves the technical field of compressor operating efficiency, and particularly the quiet dish water-cooling apparatus of a kind of screw compressor, belongs to scroll machine technical field.

Background technology

In the process of screw compressor Compressed Gas, when gas is compressed gradually along with the motion of scroll wrap, quiet dish temperature increases along with the increase of gas temperature, and the quiet panel surface temperature of screw compressor reduces along with the increase of radius, at steam vent place, temperature is the highest, and quiet plate edge place is minimum. The rising of quiet dish temperature not only affects the operating efficiency of compressor complete machine, also causes the waste of energy. Because quiet dish becomes 180 with Moving plate^oInsert, be difficult to adopt mechanical device to reduce quiet dish temperature from compression chamber is inner, but adopt heat exchange fin to carry out heat exchange at quiet dish outer surface.

The quiet dish outer surface of present stage screw compressor is all to adopt Air Flow heat exchange to reduce temperature. Because the specific heat capacity of air is less, the flow needing with moving air cooling is larger, causes the quiet dish heat exchange efficiency of screw compressor not high, and the power that uses moving air to drop into is more, causes the waste of energy, the increase of cost.

Summary of the invention

In order to address the above problem, the utility model provides a kind of screw compressor quiet dish water-cooling apparatus, is used for reducing the quiet dish temperature of screw compressor. It comprises water inlet, water pipe, and reducing bend, exhaust outlet, encapsulant, dull and stereotyped with the circle of straight tube, caulking gum pad, bolt hole, delivery port, cylinder. It is characterized in that: device is bolted with quiet dish outside wall surface, and uses the outward leakage of the anti-sealing of pad. Caulking gum pad heat exchange fin on quiet dish adjacent with two under round dull and stereotyped pressure-acting forms sector channel. Thereby be provided with encapsulant in the junction of blast pipe and reducing bend and affect heat exchange with the external leakage and the entering of air that stop water. Cylindrical wall and quiet dish outer surface leave certain gap, and this can guarantee the circulation of water, also can ensure the minimal energy loss in flow process simultaneously. Reducing bend adopted and is threaded with being connected of straight tube on disk and water pipe.

The specific heat ratio air of cooling water large, and the required water yield is less, therefore considers that the mode of water-cooled reduces the temperature of quiet dish. When after cooling water access to plant, under fin effect, be divided into multi-strand flow. The current that flow downward are accelerated in the effect current downflow of gravity, and the efficiency of heat exchange is increased; Upwards mobile current, overcome after gravity acting, and flow velocity reduces, therefore rest on the time lengthening of sector channel, can absorb more heat on quiet dish. Subsequently, what upwards flow cooling water flow out of sector channel, and the Clearance Flow reserving according to cylindrical wall and quiet dish outer surface, by delivery port flows out cooling device after mutually mixing with the cooling water flowing downward.

The utility model compared with prior art advantage is as follows:

One, this apparatus structure is simple, easy for installation, and flow media is water, and consumption is less, the convenience, with low cost of drawing materials;

Two, good cooling results, specific heat of water appearance is larger than air, can carry away more heat;

Three, cooling device, not as the container that bears pressure, does not therefore need the thicker outer wall of design, can save the energy, reduces costs.

Detailed description of the invention

Blast pipe (9) is through the straight tube on mid portion and the circle dull and stereotyped (4) of caulking gum pad (5). Locate to be connected with quiet dish (1) with bolt at bolt hole (2), when cooling water flow is out-of-date, prevent external leakage by the pad at bolt place. Circle dull and stereotyped (4) seals by caulking gum pad (5) with heat exchange fin (13) top. Blast pipe (9) is through the outlet (7) on reducing bend (6), seals with encapsulant (8). Reducing bend (6) is connected with water pipe (10) with the straight tube on circle dull and stereotyped (4).

Cooling water flows into cooling device by water inlet (11), and compressor exhaust pipe (9) is washed away to heat exchange, and under the effect of reducing bend (6), the flow direction of cooling water is contrary with the interior airflow direction of axial exhaust pipe (9). Cooling water is taken away a part of heat with heat exchange fin (13) heat exchange of quiet dish outer surface in the straight tube of circle dull and stereotyped (4), be divided into multi-strand flow by heat exchange fin (13), form in sector channel and flow with adjacent two heat exchange fins (13) at caulking gum pad (5) simultaneously. Upwards mobile cooling water overcomes after gravity, flows out sector channel, changes to flow to enter the gap that cylinder (3) wall and quiet dish (1) outer surface reserve. Cooling water is up and down the rear bleeder of (12) mixing in exit.

Claims

1. the quiet dish water-cooling apparatus of screw compressor, comprising: bolt hole (2), cylinder (3), with circle dull and stereotyped (4), caulking gum pad (5), reducing bend (6), exhaust outlet (7), encapsulant (8), water pipe (10), water inlet (11), the delivery port (12) of straight tube; It is characterized in that: cooling device and fixed scroll are with bolts, seal by pad; On fixed scroll, heat exchange fin contacts with caulking gum pad is vertical, forms sector channel; Reducing bend adopts and is threaded with the dull and stereotyped upper straight tube of circle and water pipe, and tapping adopts nonmetallic materials to seal.
