Abstract
The utility model discloses a high pressure oil-free stuffing assembly, which comprises a first throttling box group (1) and a second throttling box group (2) located on the outer side of the first throttling box group (1). The second throttling box group (2) is provided with a guide boss (3). The first throttling box group (1) and the second throttling box group (2) are provided with inner holes (4) capable of being matched with pistons. Stuffing boxes (5) are arranged in the first throttling box group (1) and the second throttling box group (2). The length of the guide boss (3) is larger than a half of the diameter of inner holes (4). The high pressure oil-free stuffing assembly greatly prolongs the service life of a stuffing and can enable the pistons to use common oil-free piston rings so as to meet the using requirement of compression.
Description
Technical field
The utility model relates to a kind of filler assembly, particularly relates to a kind of no oil packing assembly that is used for high pressure compressor.
Background technique
The filler assembly that is used for compressor generally comprises the throttling box, and stuffing box and seal ring, block ring etc. are set in the throttling box.Wherein, be positioned at outermost throttling box and be provided with a guide ledges, guide ledges stretches in the less cylinder diameter of cylinder.Such structure because the delivery temperature of compressor is higher, causes filler at high temperature to lose efficacy easily, and need keep lubricated preferably to piston ring, just can make cylinder keep proper functioning.
Therefore those skilled in the art are devoted to develop a kind of high voltage oil-free filler assembly of filler long service life.
The model utility content
Because the above-mentioned defective of existing technology, the utility model technical problem to be solved provides a kind of high voltage oil-free filler assembly of filler long service life.
For realizing above-mentioned purpose, the utility model provides a kind of high voltage oil-free filler assembly, comprises first throttle box group and the second throttling box that is positioned at the said first throttle box outside; The said second throttling box is provided with guide ledges; The said first throttle box group and the second throttling box are provided with the endoporus that can cooperate with piston rod; Be provided with stuffing box in the said first throttle box group and the second throttling box; The length of said guide ledges is greater than 1/2nd diameters of said endoporus.
Preferable, the length of said guide ledges is greater than 2/3rds diameters of said endoporus.
Preferable, the length of said guide ledges is not less than 20mm.
The beneficial effect of the utility model is: the utility model has improved the working life of filler greatly, and can make piston rod adopt common nothing oil piston ring and the usage requirement of satisfied compression.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1: as shown in Figure 1, a kind of high voltage oil-free filler assembly comprises that first throttle box group 1 and the second throttling box, 2, the second throttling boxes 2 that are positioned at first throttle box 1 outside are provided with guide ledges 3.The first throttle box group 1 and the second throttling box 2 are provided with the endoporus 4 that can cooperate with piston rod, are provided with stuffing box 5 in the first throttle box group 1 and the second throttling box 2.
In the present embodiment, the diameter of piston rod is 50mm, so the diameter of endoporus 4 also is 50mm.The length of guide ledges 3 is 43.5mm.
In other embodiments, the length of guide ledges 3 also can be other values greater than 25mm, as 26,28,30,33,35,40,45,48mm etc.To reach essentially identical technique effect.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
Claims (3)
1. high voltage oil-free filler assembly comprises first throttle box group (1) and is positioned at the second throttling box (2) in said first throttle box (1) outside; The said second throttling box (2) is provided with guide ledges (3); The said first throttle box group (1) and the second throttling box (2) are provided with the endoporus (4) that can cooperate with piston rod; Be provided with stuffing box (5) in the said first throttle box group (1) and the second throttling box (2); It is characterized in that: the length of said guide ledges (3) is greater than 1/2nd diameters of said endoporus (4).
