Abstract
The utility model discloses a stuffing box device for a high pressure reciprocating pump, which comprises a plunger piston (1), a stuffing box (2) and stuffing components (3), wherein the stuffing box (2) is sleeved on the plunger piston (1), and the stuffing components (3) are arranged in a gap between the plunger piston (1) and the stuffing box (2); and a spring (4) is also sleeved between the plunger piston (1) and the stuffing box (2), one end of the spring (4) is propped against the stuffing components (3), and the other end of the spring (4) is propped against a spring pressing sleeve (5) arranged at the back end of the stuffing box (2). The stuffing box device has a simple structure, is convenient to install, the maintenance number of the stuffing components and related components is reduced, thus the reliability of products is improved, the sealing of high pressure fluid is adaptable.
Description
Technical field
The utility model belongs to the pump technical field, relates to a kind of Stuffing box device that is used for high pressure reciprocating pump concretely.
Background technique
The existing Stuffing box device that is used for the high pressure reciprocating pump, its structure be as shown in Figure 2: filler assembly 9 pressured jack panels 10 compress its complex structure between Stuffing box 7 and the plunger 8, the machining accuracy height, execute-in-place is difficult to be grasped, the gland nut malcompression, and the filler place leaks easily, press tension, the Stuffing box heating, filler assembly damages easily, the filler wear block, even burn filler, need the professional person to adjust.Especially after filler is set up wearing and tearing, need again and tight stuffing nut, difficult in maintenance.
The model utility content
The purpose of this utility model has provided a kind of simple in structure, easy for installation, the Stuffing box device that is used for high pressure reciprocating pump in the gap that good seal performance, the wearing and tearing of energy self compensation filler are brought.
The technical solution of the utility model is as follows:
A kind of Stuffing box device that is used for high pressure reciprocating pump, comprise plunger, Stuffing box and filler assembly, described Stuffing box is sleeved on the described plunger, described filler assembly is arranged in the gap between described plunger and the Stuffing box, also be set with spring between described plunger and the Stuffing box, this spring one end and the described filler assembly spring press-cover that the other end and described Stuffing box rear end be provided with that leans leans.
Adopt the said structure key to be: in this structure, to increase spring in intermittence by adjustment plunger and Stuffing box to structure, filler assembly can play the pressure fluid in sealing load chamber and the elastic force of spring has left precompression to filler assembly, filler is set up held tightly plunger, the pressuring action of spring can be offset the gap of being brought because of wearing and tearing when even filler assembly produced wear phenomenon, do not need to change filler assembly, improved filler assembly and also reached sealing purpose in the time of working life at once.
Be provided with seal ring between described spring press-cover and the described Stuffing box.
Beneficial effect: the utility model is simple in structure, easy for installation, reduced filler assembly and associated components maintenance times, improved reliability of products, can adapt to the sealing of high pressure fluid.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 structural representation of the present utility model;
Fig. 2 is the structural representation of background technique.
Embodiment
As shown in Figure 1: a kind of Stuffing box device that is used for high pressure reciprocating pump, comprise plunger 1, Stuffing box 2 and filler assembly 3, described Stuffing box 2 is sleeved on the described plunger 1, described filler assembly 3 is arranged in the gap between described plunger 1 and the Stuffing box 2, it is characterized in that: also be set with spring 4 between described plunger 1 and the Stuffing box 2, these spring 4 one ends and described filler assembly 3 spring press-cover 5 that the other end and described Stuffing box 2 rear ends are provided with that leans leans.Be provided with seal ring 6 between described spring press-cover 5 and the described Stuffing box 2.
