Abstract
The utility model discloses a lower antithrust device of a submersible pump. The lower antithrust device comprises a coupler, a lower antithrust ring, a lower bearing, a lower shaft sleeve and a motor protector. The coupler is connected with a shaft. The lower antithrust ring, the lower bearing and the lower shaft sleeve are sleeved on the shaft in sequence from top to bottom. The motor protector is arranged outside the coupler and the lower shaft sleeve. The lower antithrust ring and the lower bearing jointly bear axial force and longitudinal force generated form a water hammer. Through utilization of the lower antithrust device, the sand content in water is improved from original 50g/m3 to now 350g/m3. The limitation that an original submersible pump can only be used in clear water is changed, and the service life of the submersible pump is prolonged.
Description
Technical field
The utility model relates to a kind of submersible pump, specifically the lower thrust device of submersible pump.
Background technique
Well is more with the progression of submersible pump, power is larger, and except the rotor deadweight was large, the axial hydraulic thrust of water pump was very large, and thrust bearing bears very high end thrust like this.For early stage well with submersible pump without lower thrust bearing, cause submersible pump under rugged environment, to use, often can occur burn-down of electric motor and pump shaft wearing and tearing.Existing submersible pump majority uses in clear water, and sand content is lower, and has ignored the abominable operating modes of environment such as seawater or Huangpu River.
The model utility content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of lower thrust device that can prolong the working life of pump and can make the submersible pump that submersible pump uses in rugged environment is provided.
For realizing above-mentioned model utility purpose; the technical solution adopted in the utility model is a kind of lower thrust device of submersible pump, comprises the coupling that joins with axle, is sleeved on successively lower thrust ring, lower bearing, the lower shaft cover on the axle and the motor protecter that is arranged on coupling and axle sleeve outside, bottom from top to bottom.This time thrust device is born axial force and the longitudinal force that produces on the water hammer jointly by lower thrust ring and lower bearing.
For improving its desertification and wear-resisting property, described lower bearing is SiC bearing.
Described lower thrust ring is the stainless steel axle sleeve, is made by 304 or 316 stainless steels.
Described bottom axle sleeve is the stainless steel axle sleeve, is made by 304 or 316 stainless steels.
Lower bearing is processed by silicon carbide material, improve its desertification and wear-resisting property, in conjunction with the bottom axle sleeve, the lower thrust ring that adopt 304 or 316 stainless steels to be made, prevent that effectively excessive the or water pump of water hammer pressure is when running up, the swing of coupling causes the vibrations of motor shaft, makes machine envelope and the lower thrust button of submersible motor impaired, uses simultaneously the bearing of this special substance, enlarge its application, can use this water pump in the more complicated field of working condition.
Beneficial effect: after using the utility model, sand content rises to present 350g/m3 by original 50g/m3 in the water, has changed the limitation performance that former submersible pump can only use in clear water, and has prolonged the working life of pump.
Description of drawings
Fig. 1 is the utility model structural representation, and 6 is axle among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, present embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these embodiments and only be used for explanation the utility model and be not used in restriction scope of the present utility model.
As shown in Figure 1, a kind of lower thrust device of submersible pump comprises thrust ring 2, silicon carbide lower bearing 3, stainless steel bottom axle sleeve 4, motor protecter 5 under the coupling 1 that joins with axle 6, the stainless steel.Bottom and coupling 1 that lower thrust ring 2, lower bearing 3 and bottom axle sleeve 4 are sleeved on the axle and bottom axle sleeve 4 from top to bottom successively join.
Bearing by lower thrust ring and bottom in the utility model bears axial force and the longitudinal force that produces on the water hammer jointly.Lower bearing is processed by silicon carbide material, improve its desertification and wear-resisting property, in conjunction with the bottom axle sleeve, the lower thrust ring that adopt 304 or 316 stainless steels to be made, prevent that effectively excessive the or water pump of water hammer pressure is when running up, the swing of coupling causes the vibrations of motor shaft, makes machine envelope and the lower thrust button of submersible motor impaired, uses simultaneously the bearing of this special substance, enlarge its application, can use this water pump in the more complicated field of working condition.The utility model makes the diving pump structure more reasonable, prolong the working life of water pump and submersible motor, and after using the utility model, sand content rises to present 350g/m3 by original 50g/m3 in the water.
