Abstract
A submersible pump intake clearance sealing device provided with a wear ring mounted fixedly to the pump body shell between a pump body shell and an impeller, and with a seal ring mounted to the corresponding impeller, is a sealing device for preventing the clearance countercurrent in the submersible pump. With the increase of the wear, the pumping efficiency can be ensured not to reduce only by removal of wear ring and replacement of the seal ring so as to reach the purpose of high efficiency and energy saving of the submersible pump.
Description
Technical field:
The utility model belongs to the gap between submersible pump water intake impeller and the housing, prevents the seal arrangement of adverse current.
Background technique:
Submersible pump places pump in water or the liquid and works, it by impeller with water suction water intake, discharge by water outlet again, have the gap between the impeller of its rotation and the shell, growth along with the operating time, wearing and tearing increase, the gap also increases thereupon, just water adverse current from the gap occurs and extrude the phenomenon generation of water intake, cause the decrease in efficiency of drawing water, can descend about 10% when serious, can not reach production requirement, manufacturer often solves this problem with the quality of fit that improves between impeller and the shell at present, causes cost of production to improve greatly like this, so need to improve.
Summary of the invention:
The purpose of this utility model provides a kind of submersible pump water intake clearance sealing device that does not have adverse current.
The technical solution of the utility model is fixed with choma 3 as shown in Figure 1 on the pump housing shell 1 between pump housing shell 1 and the impeller 2, be equipped with seal ring 4 on the corresponding impeller 2.
The utility model can be accomplished not have adverse current and produce, and along with the increase of wearing and tearing, only needs to take out choma 3, changes seal ring 4, can ensure that the efficient of drawing water does not reduce, and makes submersible pump reach energy-efficient purpose.
Description of drawings:
Fig. 1. submersible pump water intake schematic diagram of sealing device.
Wherein: 1. pump housing shell .2. impeller .3. choma .4. seal ring.
Embodiment:
The utility model is implemented by technique scheme, and choma 3 adopts stainless steel to make, and seal ring adopts rubber to make, and to different submersible pumps, install according to the concrete dimensional structure difference of each pump, but mounting structure of the present utility model is the same.
Claims (1)
1. submersible pump water intake clearance sealing device of forming by pump housing shell (1), impeller (2), it is characterized in that on the pump housing shell (1) between pump housing shell (1) and the impeller (2), being fixed with choma (3), be equipped with seal ring (4) on the corresponding impeller (2).
