Abstract
A self-regulation mechanism for a stationary plate of a commercial scroll compressor comprises an upper cover baffle (3) and a stationary plate (7), wherein the stationary plate (7) is provided with a central boss (29), and an annular outer boss (30) is arranged on the outer side of the central boss. The self-regulation mechanism is characterized in that an annular convex shoulder (31) is arranged on the upper cover baffle at the position corresponding to the annular outer boss; the upper bottom surface of the stationary plate, the outer surface of a socket (28), an inner surface of the annular outer boss (30), the inner surface of the annular convex shoulder (31) and the lower surface of the upper baffle form a middle cavity (31); and the middle cavity is communicated with an exhaust pressure cavity formed between the stationary and the movable plates through a middle pressure gas hole (33) in the stationary plate. The self-regulation mechanism has a simple structure, fully utilizes simple external structure changes of the stationary plate and the upper cover baffle to realize pressure balance, has the advantages of convenience for manufacture and low cost, and only requires normal seal rings for mounting.
Description
Technical field
The present invention relates to a kind of commercial scroll compressor, especially a kind ofly can regulate sound dish jointing end face gap automatically, guarantee the commercial scroll compressor of exhaust pressure, the quiet dish self-regulation of specifically a kind of commercial scroll compressor mechanism according to exhaust pressure.
Background technique
As everyone knows, for prevent scroll compressor the start up period or the pressure in abnormal conditions lower compression chamber is excessive causes unbalance stress inside and outside the quiet dish and cracked, people all consider pressure release measure during with quiet dish structure at the Moving plate of design scroll compressor.The most frequently used measure is to offer intermediate pressure at Jing Panshang to get pore; Pressure in the hyperbaric chamber is entered in the pressure-releasing chamber, under the normal condition, rely on the pressure in the pressure-releasing chamber to make quiet dish and Moving plate reach desirable applying; Make the float of pressure-releasing chamber open pressure release under the abnormal conditions; This just requires between quiet dish and loam cake baffle plate, to install float and comes pressure release, causes complex structure, inconvenient installation.
Summary of the invention
The objective of the invention is that to let out the quiet adjustment debit that assembling device prevents that abnormal pressure from causing bad to needing on the quiet dish of existing scroll compressor to install; Thereby cause complex structure; Manufacture cost strengthens; The problem of inconvenient installation, thus a kind of pressure-releasing chamber that utilizes of design realizes that quiet dish stress balance prevents the broken quiet dish self-regulation of the commercial scroll compressor mechanism of quiet dish under the abnormal pressure.
Technological scheme of the present invention is:
The quiet dish self-regulation of a kind of commercial scroll compressor mechanism; Comprise loam cake baffle plate 3 and quiet dish 7; Described quiet dish 7 is provided with the central boss 29 in the socket 28 that inserts on the loam cake baffle plate 3; Be provided with annular outer platform 30 in the outside of central boss 29; It is characterized in that being provided with annular convex shoulder 31 with annular outer platform 30 relative position places on the described loam cake baffle plate 3, the internal surface of the outer surface of the upper bottom surface of described quiet dish 7, socket 28, the internal surface of annular outer platform 30, annular convex shoulder 31 and the lower surface of loam cake baffle plate form an intermediate cavity 32, and described intermediate cavity 32 is got the discharge plenum that forms between pore 33 and the sound dish through the intermediate pressure on the quiet dish and is connected; Between described socket 28 and central boss 29, be equipped with and prevent that pressurized gas from getting into the high-pressure seal ring 4 of intermediate cavity 32, the low pressure seal circle 5 that the pressure that prevents in the intermediate cavity 32 leaks to low pressure chamber is installed on the junction plane of annular outer platform 30 and annular convex shoulder 31.
Described annular outer platform 30 is provided with the mount grooves 37 that annular resilient pad 6 is installed, and cyclic spring pad 6 is installed in the mount grooves 37, and its upper surface offsets with the low pressure seal circle 5 that part is inserted in the mount grooves 37.
Beneficial effect of the present invention:
The present invention has saved traditional pressure release and has used floating valve, through the pressure reduction inside and outside the timely balance compressor of the pressure-releasing chamber of setting up between loam cake baffle plate and the quiet dish, guarantees that quiet dish stress balance can be not broken because of high pressure.
The present invention is simple in structure, all utilizes the change of the simple form structure of quiet dish and loam cake baffle plate to realize the balance of pressure, has easily manufacturedly, and cost is low, only needs normal seal ring to install during installation and gets final product.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1.
The quiet dish self-regulation of a kind of commercial scroll compressor mechanism; Comprise loam cake baffle plate 3 and quiet dish 7; Described quiet dish 7 is provided with the central boss 29 in the socket 28 that inserts on the loam cake baffle plate 3; Be provided with annular outer platform 30 in the outside of central boss 29; Be provided with annular convex shoulder 31 with annular outer platform 30 relative position places on the described loam cake baffle plate 3, the internal surface of the outer surface of the upper bottom surface of described quiet dish 7, socket 28, the internal surface of annular outer platform 30, annular convex shoulder 31 and the lower surface of loam cake baffle plate form an intermediate cavity 32, and described intermediate cavity 32 is got the discharge plenum that forms between pore 33 and the sound dish through the intermediate pressure on the quiet dish and is connected; Between described socket 28 and central boss 29, be equipped with and prevent that pressurized gas from getting into the high-pressure seal ring 4 of intermediate cavity 32, the low pressure seal circle 5 that the pressure that prevents in the intermediate cavity 32 leaks to low pressure chamber is installed on the junction plane of annular outer platform 30 and annular convex shoulder 31.Described annular outer platform 30 is provided with the mount grooves 37 that annular resilient pad 6 is installed, and cyclic spring pad 6 is installed in the mount grooves 37, and its upper surface offsets with the low pressure seal circle 5 that part is inserted in the mount grooves 37.
Working procedure of the present invention is following;
Under the normal condition; When compressor does not start; The elastic force that cyclic spring pad 6 produces moves down quiet dish and fits with the end face molded lines of Moving plate, makes the suitable startup gap of maintenance between the sound dish, during proper functioning; The pressure that pressure chamber between the sound dish produces is got pore 33 through intermediate pressure and is got in the intermediate cavity 32; Intermediate cavity 32 produces a downward thrust to overcome the strength that quiet dish is moved up because of the pressure between the sound dish, and quiet dish receives downward power and the power that makes progress to reach balance, makes compressor can normally accomplish compression work.Get between the sound dish or outlet valve when occurring causing the pressure anomaly in the hyperbaric chamber between the sound dish unusually as liquid medium; Quiet dish receives power upwards greater than downward power; Make Moving plate separate with quiet dish; Lost compression function, thereby reached the purpose of pressure release, protection Moving plate and quiet dish scrollwork are not damaged.Improved Security greatly, owing to need not to install the pressure release parts, made overall structure simple simultaneously, it is also greatly convenient that manufacturing is installed.
The present invention does not relate to all identical with the existing technology existing technology that maybe can adopt of part and realizes.
