Abstract
The utility model relates to a kind of Dyeing printing pump with machine sealing chamber, comprises the pump housing, and impeller is installed in the pump housing, and a side of the pump housing arranges pump cover, and the opposite side mounting bracket of the pump housing, installs pump shaft by bearing in bracket, and pump shaft is connected with impeller through the pump housing; On the described pump housing, be provided with axis hole, machine envelope is set between pump shaft and the axis hole of the pump housing; It is characterized in that: the inner side at described axis hole arranges the through hole being connected with axis hole, the internal diameter of through hole is become greatly to the other end gradually by the one end near axis hole, forms machine sealing chamber.Described machine sealing chamber is horn-like.The Dyeing printing pump with machine sealing chamber described in the utility model has changed in prior art the shape of machine sealing chamber on the Dyeing printing pump pump housing, and machine sealing chamber is expanded; Thereby the heat that machine envelope friction pair produces can be taken away in time, and the normal use of guarantee machine envelope, prevents that machine sealing position from leaking effectively, thereby ensures that the use of Dyeing printing pump is more reliable.
Description
Technical field
The utility model relates to a kind of Dyeing printing pump, and especially a kind of Dyeing printing pump with machine sealing chamber, belongs to mechanical structure technical field.
Background technique
In prior art, print and dye pump structure generally as shown in Figure 1, comprise pump housing 1a, pump cover 2a, impeller 3a and pump shaft 4a, machine envelope 5a is set between pump shaft 4a and pump housing 1a.But in existing structure, machine envelope 5a is arranged in the cylindrical axis hole (as shown in Figure 2) on pump housing 1a, after installing, between the inwall of the axis hole of machine envelope 5a and pump housing 1a, forms circular machine sealing chamber.Because this machine sealing chamber space is less, in Dyeing printing pump working procedure, the pressure of machine envelope present position is less than normal, and the heat that machine envelope friction pair produces can not be pulled away in time, causes machine seal heat to burn out, and leakage phenomenon easily occurs.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Dyeing printing pump with machine sealing chamber is provided, and changes the shape of machine sealing chamber, and the heat that machine envelope friction pair is produced can be pulled away in time, effectively the normal use of guarantee machine envelope.
The technological scheme providing according to the utility model, described in there is the Dyeing printing pump of machine sealing chamber, comprise the pump housing, impeller is installed in the pump housing, and a side of the pump housing arranges pump cover, the opposite side mounting bracket of the pump housing, in bracket, by bearing, pump shaft is installed, pump shaft is connected with impeller through the pump housing; On the described pump housing, be provided with axis hole, machine envelope is set between pump shaft and the axis hole of the pump housing; It is characterized in that: the inner side at described axis hole arranges the through hole being connected with axis hole, the internal diameter of through hole is become greatly to the other end gradually by the one end near axis hole, forms machine sealing chamber.
Described machine sealing chamber is horn-like.
The Dyeing printing pump with machine sealing chamber described in the utility model has changed in prior art the shape of machine sealing chamber on the Dyeing printing pump pump housing, and machine sealing chamber is expanded; Thereby the heat that machine envelope friction pair produces can be taken away in time, and the normal use of guarantee machine envelope, prevents that machine sealing position from leaking effectively, thereby ensures that the use of Dyeing printing pump is more reliable.

Fig. 1 is the structural representation of Dyeing printing pump in prior art.
Fig. 2 is the structural representation of the pump housing of Dyeing printing pump in prior art.
Fig. 3 structural representation of the present utility model.
Fig. 4 is the structural representation of the Dyeing printing pump pump housing described in the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 3～Fig. 4: as described in there is machine sealing chamber Dyeing printing pump comprise the pump housing 1, pump cover 2, impeller 3, bracket 4, bearing 5, pump shaft 6, axis hole 7, through hole 8, machine envelope 9 etc.
As shown in Figure 3, the utility model comprises the pump housing 1, the interior installation impeller 3 of the pump housing 1, and a side of the pump housing 1 arranges pump cover 2, and the opposite side mounting bracket 4 of the pump housing 1, installs pump shaft 6 by bearing 5 in bracket 4, and pump shaft 6 is connected with impeller 3 through the pump housing 1; On the described pump housing 1, be provided with axis hole 7, machine envelope 9 is set between pump shaft 6 and the axis hole of the pump housing 1; As shown in Figure 4, in the inner side of described axis hole 7, the through hole 8 being connected with axis hole 7 is set, the internal diameter of through hole 8 is become greatly to the other end gradually by the one end near axis hole 7, forms trumpet-shaped machine sealing chamber.
The Dyeing printing pump with machine sealing chamber described in the utility model has changed in prior art the shape of machine sealing chamber on the Dyeing printing pump pump housing, and machine sealing chamber is expanded; Thereby the heat that machine envelope friction pair produces can be taken away in time, and the normal use of guarantee machine envelope, prevents that machine sealing position from leaking effectively, thereby ensures that the use of Dyeing printing pump is more reliable.
