Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Sealing of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Such as Fig. 1 and shown in Figure 2, a kind of single-stage double-suction middle-opening formula centrifugal pump, comprise be used to the pump housing 110 that holds impeller, running shaft 120, be used for two Sealings between the pump housing 110 and running shaft 120, sealing, and two bearing suppories 130 being located at running shaft 120 two ends, running shaft 120 passes the pump housing 110 and is connected with impeller.
Be equipped with Sealing cooling chamber 140, Sealing cooling water inlet 150, Sealing coolant outlet 160 and sparge water entrance 170 on the Sealing.Sealing cooling chamber 140 is connected with Sealing cooling water inlet 150 and Sealing coolant outlet 160, passes into external cooling water, reaches the effect that absorbs and transmit temperature, simultaneously, injects sparge water to sparge water entrance 170 and can make running shaft 120 coolings.
Particularly, as shown in Figure 1, two one of Sealings are that mechanical sealing element 180 and one are packing seal element 190.
