Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides a kind of side entering type agitator of auxiliary seal, comprise motor 1, gear reduction unit 2, power transmission shaft 3, frame 4, clamping coupling 5, mechanical seal 6, shaft 9 and stirring vane 10, the output shaft of described motor 1 is connected with the power shaft of gear reduction unit 2, the output shaft of described gear reduction unit 2 is connected with power transmission shaft 3, described power transmission shaft 3 is connected with shaft 9 by clamping coupling 5, described stirring vane 10 is installed on one end of shaft 9, described power transmission shaft 3 is installed on one end of frame 4, described shaft 9 is installed on the other end of frame 4, described mechanical seal 6 is installed on shaft 9, this side entering type agitator also comprises the flange seat 8 that is installed on mechanical seal 6 outsides, and be installed on the auxiliary seal 7 in flange seat 8 outsides, described mechanical seal 6 and flange seat 8 lay respectively at inner side and the outside of frame 4, described flange seat 8 is provided with annular seal space 8.1, described auxiliary seal 7 is provided with the sealing lip corresponding with annular seal space 8.1 7.1.
In the present embodiment, described annular seal space 8.1 is annular seal space, and described sealing lip 7.1 is annular seal lip, and annular seal lip can coordinate to realize with annular seal space the function of auxiliary seal.
In the present embodiment, annular seal lip 7.1 is wherein that circular arc coordinates with the cooperation place, end of annular seal space 8.1, can increase like this its sealing property.
In the present embodiment, described auxiliary seal 7 is interference fit with shaft 9.
When after side entering type agitator long-play, mechanical seal 6 is damaged, and need to change it, and its concrete Renewal process is as follows:
The first step, cut off the electricity supply, Bolt dismantling on the bonnet baffle plate of gear reduction unit 2 is fallen, and at lifting bolt of the end of power transmission shaft 3 (being the output shaft of gear reduction unit 2) installation, then pull lifting bolt (pulling power transmission shaft 3) by (in Fig. 1 left) backward, the sealing lip 7.1 of auxiliary seal 7 is snapped in the annular seal space 8.1 of flange seat 8, reach the effect of auxiliary seal material;
