Abstract
The utility model discloses an oilless packing assembly of a piston type compressor, comprising a sealer seat, a seal packing and a pressure cover which are sequentially connected; the seal packing close to the pressure cover is connected with an air collection box; a flow choking ring and a throttling shaft sleeve are arranged between the seal packing and the sealer seat; and the throttling shaft sleeve comprises a throttling box and a throttling ring positioned in the throttling box. The oilless packing assembly of the piston type compressor is smart in conception and simple in structure, can normally work under the working condition without lubricating oil, and has long service life and good sealing effect.
Description
Technical field
The utility model relates to a kind of piston compressor filler assembly, and relating in particular to a kind of piston compressor does not have the oil packing assembly.
Background technique
Piston compressor is a kind of moving equipment, is mainly used in lift gas pressure.Compresser cylinder is the compressed core component of gas, dwindles the volume of gas by the to-and-fro motion of piston, and the pressure of gas is improved simultaneously.By the characteristics of conventional construction as can be known, parts must be set can the separation gas zone and the crosshead of motion, and can allow the normal linear reciprocating motion of piston rod, and these parts often are called as filler assembly.
At present, widely used filler assembly is made up of a plurality of stuffing boxes usually, and the pressure decline that realizes cylinder internal leakage gas jointly farthest reduces the external leakage of gas to normal pressure.Configuration one cover black box (being filler) comprises 2-3 seal ring in each stuffing box, and seal ring is provided with radial indentation and circumferential spring with automatic compensation gauge wear.
The filler assembly work and the abrasion mechanism of conventional construction are: when new filler is started working, overlap filler near one of cylinder side and at first bear most of pressure difference, at first wearing and tearing; When the sealability variation, bear most of pressure difference by the second cover filler, progressively pressure difference is transmitted thus and reduced force value; Last cover filler outside is an atmosphere, can make its a large amount of wearing and tearing, seal failure after final High Pressure Difference is accumulated at herein; The order that filler assembly lost efficacy is to begin to spread all filler groups from last cover filler.The subject matter that this filler assembly exists is: each overlaps, and filler all need bear big pressure difference, pressure surge is big; The sealing of filler is mainly from blocking action; The high pressure of gas in the cylinder and fluctuation are not handled fully and utilized.
The model utility content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of piston compressor not have the oil packing assembly.This no oil packing assembly is skillfully constructed, simple in structure, can be under the operating mode of unlubricated oil proper functioning, long service life, good sealing effect.
For achieving the above object, the utility model solves the technological scheme that its technical problem adopts and is:
A kind of piston compressor does not have the oil packing assembly, comprise the sealer seat, stuffing box packing and the gland that connect successively, stuffing box packing near gland is connected with collector box, be provided with block ring and restrictor sleeve between described stuffing box packing and the sealer seat, this restrictor sleeve comprises the throttling box and is positioned at the restrictor ring of throttling box.
As optimal way, the endoporus of described restrictor sleeve is provided with the labyrinth annular groove.
As optimal way, described stuffing box packing comprises first seal ring, second seal ring and packing ring successively, this first seal ring and second seal ring are by three annulus that the ring section is formed of fitting mutually between opening, each ring section opening of first seal ring is positioned at annulus radially, each ring section external annulus opening of second seal ring is an angle, and the internal ring wall opening is a radial opening.
As optimal way, the angle between each ring section external annulus opening of described second seal ring and internal ring wall opening is the right angle.
Adopt said structure, key is:
1, the utility model is being provided with block ring near cylinder side.Working procedure according to gas in the piston type compressor cylinder draws rule, escape gas pressure into filler assembly and be one with turnover air cavity pressure be upper and lower, with the pulsatile change curve of pistons work cycle synchronisation.Block ring can stop the gas pressure of pulsation and isolate, and favourable operating conditions is provided for the filler group of back, pressure reduction minimizing, in stable condition.
2, the utility model is being provided with restrictor sleeve near cylinder side, and expenditure and pressure when gas passes through is to alleviate the load of filler group; Restrictor sleeve endoporus car has many labyrinths annular groove to strengthen restriction effect.
3, each ring section opening of first seal ring of the present utility model is positioned at annulus radially, and each ring section external annulus opening of second seal ring is an angle, and the internal ring wall opening is a radial opening, can fully prolong the comprehensive life of filler assembly.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is skillfully constructed, simple in structure, can be under the operating mode of unlubricated oil proper functioning, long service life, good sealing effect.
