Abstract
The invention discloses a high-pressure padding sealing device for a compressor. The high-pressure padding sealing device comprises a throttling ring, a main sealing ring, a flow stopping ring and two nitrogen sealing rings which are sequentially arranged from inside to outside, wherein a spring is arranged on the annular edge of the flow stopping ring; the flow stopping ring and the main sealing ring are connected with each other through a cylindrical pin on the outer side of the flow stopping ring; a nitrogen sealing ring spring is arranged on the annular edge of each nitrogen sealing ring; a sealing ring incision is formed on the annular inner side; and the two nitrogen sealing rings are connected with each other through nitrogen sealing ring cylindrical pins. The high-pressure padding sealing device has the advantages that the sealing rings have an extremely good sealing effect and are easy to assemble and convenient to maintain; the production process is reduced, and the manufacturing cost is reduced; the temperature of a piston rod is reduced, so that the service life of the piston rod is prolonged; the intensity of the flow stopping ring is improved, so that cold flow is avoided; and a phenomenon that the piston rod is pulled to be damaged is avoided.
Description
Technical field
The present invention relates to a kind of compressor high pressure stuffing seal and method.
Background technique
At present, the filler of compressor is the Sealing that wraps on the piston rod, and filler is made up of many groups ring, is included in the stuffing box, and functions such as lubricated, cleaning, cooling, sealing, temperature and pressure are provided during operation.Its effect is to stop the interior gas of cylinder between piston rod and Sealing, to leak.Cardinal principle is that gas gets in the annular groove of stuffing box from axial clearance and radial clearance, by gas pressure packing ring is fitted tightly respectively with piston rod surface and annular groove end face and realizes sealing.
Mostly the structure of the high pressure filler conventional design of using at present is a block ring, a tangential ring and a radial ring.Because the restriction of the annular groove degree of depth, the thinner thickness of tangential ring and radial ring, the high pressure air muscle power that it bears is easy to make its distortion and produces more frictional heat with piston rod rigid contact of pulsing; The temperature of piston rod is raise, thereby reduced working life, the sealability of filler also weakens simultaneously; Simultaneously, the lubricant oil because Reciprocting piston compressor will be annotated in filler when operation, tangential ring, radial ring often find that when opening and inspecting greasy dirt is more; Tangential ring, radial ring are clung, after tangential ring, the radial ring combination, axially do not have the gap basically; Cause seal ring to float, leaking appears in packing seal, produces and loses efficacy.
When surveying the rod seal of single Reciprocting piston compressor specific to axle, because it belongs to the single-acting type, pressure reduction is very little again simultaneously, adopts traditional packing seal mode to be difficult to realize the sealing to piston rod.Therefore, in the use of this type of device, exist because the piston rod packing sealing problem causes problems such as the piston rod temperature is too high, packing seal leakage always.
Summary of the invention
The purpose of this invention is to provide a kind of compressor high pressure stuffing seal and method, to solve above technical barrier.
A kind of compressor high pressure stuffing seal of the present invention; Comprise restrictor ring, main seal ring, block ring and two nitrogen-sealed rings of setting gradually from the inside to the outside; Said block ring ring edge is provided with spring, and block ring is connected through the straight pin that is located at the block ring outside with main seal ring; Said nitrogen-sealed ring ring edge is provided with nitrogen-sealed ring spring, and annular inboard is provided with the seal ring otch, and two nitrogen-sealed rings are connected through nitrogen-sealed ring straight pin.
Utilize the encapsulating method of above-mentioned compressor high pressure stuffing seal, it may further comprise the steps:
1) the cleaning restrictor ring is surperficial, and restrictor ring is mounted to the high cylinder pressure side;
2) cleaning block ring and main seal ring surface meets main seal ring to installation on the pressure side, and in the main seal ring outside block ring is installed, and main seal ring is connected with block ring through straight pin, and axial clearance is matched with compressor arrangement;
3) cleaning nitrogen-sealed ring surface will be installed on the block ring outside through two nitrogen-sealed rings that nitrogen-sealed ring straight pin connects, and make the seal ring otch on two nitrogen-sealed rings be 90 ° of angular misalignments.
Beneficial effect of the present invention is: seal ring seal effect used in the present invention is splendid, installs simply, and is easy to maintenance, and manufacturing procedure reduces the manufacture cost reduction; The temperature of piston rod reduces, and has prolonged the working life of piston rod, and since the increase of block ring intensity avoided cold flow, thereby made piston rod phenomenon can not occur pulling.
