Abstract
The utility model provides a sewage submersible electric pump with high lift, which comprises a motor, a water inlet joint, a base, guide vanes and an impeller, wherein, the water inlet joint is arranged on the base. The upper end of the water inlet joint is fixedly connected with the motor, and one side thereof is provided with a low-pressure water passage. The guide vanes are arranged in the water inlet joint. The impeller connected with an output shaft of the motor by keys is arranged in the guide vanes. The utility model is characterized in that a high-pressure water passage is arranged at one side of the water inlet joint and hermetically communicated with a flow passage cavity of the impeller. As the utility model is provided with the high-pressure water passage which is hermetically communicated with the flow passage cavity of the impeller, high-pressure water flowing out of the impeller passes through the special high-pressure water passage, the pressure is not applied to a mechanical seal any more, the water in contact with the mechanical seal is outside low-pressure water, the pressure on the seal is low, and the mechanical seal can be safely and reliably sealed.
Description
Technical field
The utility model provides a kind of high-lift immersed sewage electric pump, belongs to the Submerged Motor Pumps technical field.
Background technique
Submerged Motor Pumps is owing to have the outstanding advantage of simplifying pump structure and saving the pumping plant construction investment, and application area is more and more wider aspect municipal administration, industrial and mineral, enterprise and agriculture plumbing, and is also more and more higher to the requirement of Submerged Motor Pumps.Wherein mechanical seal is exactly the key of Submerged Motor Pumps, and particularly high-lift Submerged Motor Pumps seals just even more important.Be to improve its mechanical sealing performance by the sealing load that improves Submerged Motor Pumps in the past, defective is easy damage, and the cost height.
The model utility content
The purpose of this utility model just provide a kind of can overcome above-mentioned defective, simple in structure, cost is low, the high-lift immersed sewage electric pump of excellent working performance.Its technological scheme is:
Comprise motor, water inlet joint, base, stator and impeller, wherein the water inlet joint is installed on the base, fixedly connected with motor in its upper end, the one side is provided with the low-pressure water passage, stator is installed in in the water joint, the impeller that is connected through key with the output shaft of motor is installed in the stator, it is characterized in that: the flow passage chamber sealing UNICOM that high pressure water passage and impeller are set in a side of water inlet joint.
The utility model compared with prior art; because by the high pressure water passage that seals UNICOM with the impeller channel chamber is set; the high pressure water that impeller is come out passes through special high pressure water passage; no longer pressure is imposed on mechanical seal place; and with the contacted water of mechanical seal place be extraneous low-pressure water; reduce the pressure of sealing part, guarantee the safe and reliable sealing of mechanical seal.
Description of drawings
Fig. 1 is the utility model embodiment's a part-structure schematic representation;
Among the figure: 1, motor 2, water inlet joint 3, base 4, stator 5, impeller 6, low pressure water channel 7, output shaft 8, key 9, high pressure water passage
Embodiment
During work, the high pressure water that impeller 5 comes out no longer imposes on mechanical seal place with pressure by special high pressure water passage 9, and with the contacted water of mechanical seal place be extraneous low-pressure water, reduce the pressure of sealing part, guarantee the safe and reliable of mechanical seal.
