Abstract

The utility model discloses a pump split packing gland comprising a gland body, wherein the gland body is divided into an upper haft body (1) and a lower haft body (2) through radially splitting at a bolt (3) and axially half-and-half splitting at a middle compression ring (4). The pump split packing gland is simple in structure and reliable in performance, and is convenient for disassembling when filler filling is conducted in the pump using process and when the packing gland is damaged in the pump using process.

Description

Pump is with dividing half formula gland

Technical field

The utility model relates to a kind of Gland, particularly relates to a kind of pump with dividing half formula Gland.

Background technique

Usually gland adopts Fig. 1 structure, adopts the gland of Fig. 1, pump must be taken apart when gland damages.Must stop enough spaces during the pump design so that the filling material.Adopt the gland of the branch half of Fig. 2, when gland is dismantled, must will divide half gland and pump connecting place nut to unclamp earlier, could divide half gland to take apart after the gland hauling-out is unclamped the connecting bolt on the gland again.

The model utility content

Technical problem to be solved in the utility model provides a kind of pump and in use loads gland damage pump for convenience detach branch half formula gland in material and the pump use.

In order to solve the problems of the technologies described above, pump that the utility model provides comprises the gland body with dividing half a formula gland, and described gland body adopts at the bolt place radially subdivision, is decomposed into branch halfbody and lower minute halfbody at axial double subdivision in middle pressure ring place.

Described gland body adopts at the bolt place radially double subdivision, is decomposed into branch halfbody and lower minute halfbody at axial double subdivision in middle pressure ring place.

Adopt the pump of technique scheme with dividing half formula gland, because the gland body adopts at the bolt place radially double subdivision, is decomposed into branch halfbody and lower minute halfbody at axial double subdivision in middle pressure ring place, when pump filling material and gland damage, only need and to divide upper minute halfbody of half gland and lower minute halfbody and pump connecting place nut to unclamp, upper minute halfbody and lower minute halfbody can be hauled out and take apart, very convenient.Upper filler is taken the space that branch half gland can be saved filler on the pump apart, can make the pump configuration design compacter.Because the pump span reduces, and has improved the stability of pump operation.Owing to change the very convenient time of saving the pump maintenance of filler and gland, simultaneously, be easy to realize the standardization producing in serial form of gland.

In sum, the utility model is that a kind of pump in use loads gland damage pump branch half formula gland for convenience detach and simple in structure, dependable performance in material and the pump use.

Description of drawings

Fig. 1 is existing whole filling material gland structure schematic diagram;

Fig. 2 is existing half the filling material gland structure schematic diagram that divides;

Fig. 3 is that pump of the present utility model is with dividing half formula Gland package assembly schematic representation;

Fig. 4 is that pump of the present utility model is with dividing half formula gland to split schematic diagram;

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 3 and Fig. 4, the gland body adopts at bolt 3 places radially double subdivision, axial double subdivision is decomposed into branch halfbody 1 and lower minute halfbody 2 at middle pressure ring 4 places.

Referring to Fig. 3 and Fig. 4, pump is with dividing half gland to carry out radially double subdivision by bolt 3 places on the gland median surface, 4 places carry out subdivision double at middle pressure ring, realized that gland becomes two the same upper minute halfbody 1 and lower minute halfbodies 2 by an integral body, when pump filling material and gland damage, only need and to divide upper minute halfbody 1 and lower minute halfbody 2 of half gland to unclamp with pump connecting place nut, upper minute halfbody 1 and lower minute halfbody 2 can be hauled out and take apart, very convenient.Upper filler is taken the space that branch half gland can be saved filler on the pump apart, can make the pump configuration design compacter.Because the pump span reduces, and has improved the stability of pump operation.Owing to change the very convenient time of saving the pump maintenance of filler and gland, simultaneously.Be easy to realize the standardization producing in serial form of Gland.

Claims

1. a pump comprises the gland body with dividing half formula Gland, it is characterized in that: described gland body adopts at bolt (3) and locate radially subdivision, locate axial double subdivision at middle pressure ring (4) is decomposed into and divides halfbody (1) and following minute halfbody (2).

2. pump according to claim 1 is characterized in that with dividing half a formula gland: described gland body adopts at the bolt place radially double subdivision, at axial double subdivision in middle pressure ring place.
