Abstract
The utility model relates to a double-end-surface submersible pump sealing device which comprises a shaft sleeve, a rotating seal ring assembly and a stationary seal ring assembly, wherein the shaft sleeve is sheathed on the external side of a rotating shaft and the end part of the shaft sleeve is fixedly connected with a rotating seal ring seat through a set screw. The device is characterized in that the rotating seal ring assembly is arranged at the lower end of the rotating seal ring seat, an O-ring is arranged between the internal side of the rotating seal ring seat and the shaft sleeve, a rotating seal ring is arranged at a position at which the lower end of the rotating seal ring seat is attached onto the rotating seal ring assembly, a connecting flange is arranged at the external end of the rotating seal ring assembly, the stationary seal ring assembly is clamped on the internal side of the connecting flange, and a stationary seal ring is arranged between the stationary seal ring assembly and the connecting flange. The double-end-surface submersible pump sealing device has the beneficial effects that since the rotating seal ring assembly and the stationary seal ring assembly are attached onto each other in a sealing way and one side of the rotating seal ring and one side of the stationary seal ring are respectively provided with one O-ring, the sealing performance of the device can be further improved; and components on the end surfaces of the rotating seal ring and the stationary seal ring can be easily replaced and the sealing performance of the junction can be ensured.
Description
Technical field
The utility model relates to the submersible pump sealing configuration, relates in particular to a kind of Double End submersible pump seal arrangement.
Background technique
Submersible pump is as the visual plant of deep-well water lift, the work that pulls the plug of whole in use unit, underground water is extracted the face of land, can be used for that domestic water, mine are speedily carried out rescue work, industrial cooling, field irrigation, seawater promote, steamer transfer carry, fountain view, hot spring bathing etc., also can be used for water lift engineerings such as river, reservoir, water channel.The Double End submersible pump seal arrangement sealability and the rotating shaft stability of prior art can not be taken into account, and inefficiency causes later stage labor intensity big; In addition, because of its mechanical structure causes manufacture difficulty big, rotating ring and static components lack indispensable sealing configuration.
The model utility content
At above defective, the purpose of this utility model provides a kind of Double End submersible pump seal arrangement that long-time accurately operation, wear-resisting property are strong, can keep the rotating shaft slow-roll stabilization that helps, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of Double End submersible pump seal arrangement, comprise axle sleeve, moving ring assembly, static components, the rotating shaft outside is with axle sleeve, the end of axle sleeve is by the fixedly connected rotating seat of Cock screw, described rotating seat lower end is provided with moving ring assembly, be provided with the O RunddichtringO between described rotating seat inboard and the axle sleeve, rotating seat lower end and moving ring assembly joint place are provided with seal ring of moving ring; Described moving ring assembly outer end is provided with connecting flange, and this connecting flange inboard accompanies static components, is provided with the stationary ring seal ring between described static components and the connecting flange.
The beneficial effect of Double End submersible pump seal arrangement described in the utility model is: fit by moving ring assembly and static components sealing, and in rotating ring and stationary ring one side the O RunddichtringO is set respectively, can further improve its sealability; The assembly of rotating ring and stationary ring end face is changed easily, has guaranteed the sealability of junction.
