Background
The deep well pump is a pump immersed in an underground water well to pump and convey water, after a motor works, the water in the well is pumped up, and because the internal impeller rotates at a high speed, liquid in the well rotates along with the impeller, the liquid flies away from the impeller to be ejected outwards under the action of centrifugal force, the speed of the ejected liquid in a pump shell diffusion chamber is gradually slowed down, the pressure is gradually increased, and then the ejected liquid flows out of a discharge pipe at the outlet of the pump.
The traditional deep-well pump generally adopts the structure of a single oil chamber, and is sealed through a single sealing cover, if the sealing is not firm, liquid can leak along a motor shaft, and the liquid (oil-water mixture) in the oil chamber enters the motor to cause the motor to burn out, so that the sealing reliability of the deep-well pump directly relates to the service life of the motor.
The closing cap itself has great wearing and tearing in deep-well pump working process, in order to reduce the influence that wearing and tearing brought, closing cap itself also needs to soak fluid, but because the grease chamber is in the oiling process, because inside atmospheric pressure reasons lead to unable to topple up fluid to the mounting means of deep-well pump is vertical installation, can not incline, so the closing cap that is located the top can't dip into fluid, generally relies on fluid to splash to lubricate it on the top closing cap in the traditional process, and very unstable, the wearing and tearing of closing cap over time are still obvious.
To this end, the present utility model will propose a solution to the technical problem described above.

Detailed Description
The utility model is further described with reference to the following specific examples:
As shown in fig. 1-2, an oil chamber sealing structure of a deep well pump is characterized in that: the oil chamber shell comprises a top cover 1, a motor shaft 2 and an integrally formed oil chamber shell 3, wherein a first sealing cover 11 and an oil filling hole 12 are arranged on the top cover 1, a partition plate 33 is formed in the middle of the oil chamber shell 3, the partition plate 33 divides the oil chamber shell 3 into an upper oil chamber 31 and a lower oil chamber 32, a second sealing cover 34 and a third sealing cover 35 are arranged at the upper end and the lower end of the partition plate 33, a bearing 36 is arranged at the bottom of the oil chamber shell 3, a first spring 41 is arranged between the first sealing cover 11 and the second sealing cover 34, a second spring 42 is arranged between the third sealing cover 35 and the bearing 36, the oil chamber shell 3 is integrally formed, the oil filling hole 12 is arranged on the top cover 1 and filled with oil into the oil chamber, the partition plate 33 is divided into an upper part and a lower part, the first sealing cover 11 of the upper oil chamber is generally contained in use, double protection is arranged by dividing the partition plate 33, the upper part is damaged, the other half of the oil chamber can still be guaranteed to play a role in protecting, the sealing cover correspondingly has three sealing blocks, the first sealing cover 11, the second sealing cover 34 and the third sealing cover 35 are arranged, the first sealing cover and the second sealing cover 35 are fixed by the first sealing cover and the second sealing cover 41.
