Description

High-lift submersible pump

Technical Field

A high-lift submersible pump belongs to the technical field of submersible pumps.

Background

The submersible pump is an important device for pumping water from a deep well. When the water-cooled underground water extraction unit is used, the whole unit is submerged to work, and underground water is extracted to the ground surface, and the water-cooled underground water extraction unit is commonly used in the fields of domestic water, mine emergency rescue, industrial cooling, farmland irrigation, seawater lifting, ship load regulation and the like. It can also be used for central air-conditioning cooling, heat pump set, cold pump set, city, factory, railway, mine and construction site drainage.

Generally, the flow rate can reach 5-650 m/h, and the lift can reach 10-550 m. After the pump is started, the impeller rotates at a high speed, the liquid in the impeller rotates along with the blades, the liquid flies away from the impeller and is ejected outwards under the action of centrifugal force, the speed of the ejected liquid in the pump shell diffusion chamber gradually becomes slow, the pressure of the ejected liquid gradually increases, and then the ejected liquid flows out from the pump outlet and the discharge pipe. Among the prior art, the structural design of immersible pump itself is reasonable inadequately for in certain length, hardly accomplish higher lift, and be difficult to guarantee the intensity of the pump body self on the basis of high lift, can not satisfy the demand of high lift, high strength.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: overcomes the defects of the prior art, and provides the high-lift submersible pump with high lift, high strength and simple structure.

The utility model provides a technical scheme that its technical problem adopted is: this high-lift immersible pump, including the contrary valve body, the pump body, the section of intaking and the pump shaft that connect in order, the pump body includes that the multiunit axial concatenates at the epaxial pump case of pump, all assembles a set of impeller, its characterized in that alone in every group pump case: a group of connecting sleeves are sleeved outside the multiple groups of pump shells, and the two end parts of the connecting sleeves are respectively connected with the check valve body and the water inlet section.

The utility model discloses change the pump body structural style of traditional immersible pump, adopt whole suit adapter sleeve's structure, closely concatenate the multiunit pump case on the pump shaft, the clearance between two liang of multiunit pump case has been saved, also saved the structure that two liang of between need drawknot muscle to connect, multiunit drawknot muscle isotructure has been saved, this part connection space has also correspondingly been saved, thereby make the whole length of the pump body shorten, therefore, length does not increase, on the basis that shortens even, the bulk strength of the pump body has been strengthened, and the lift of increase immersible pump that can relax, realize the purpose of high lift.

The pump casings are fixed on the pump shaft in a clamping mode through steps arranged on the outer edge, and sealing rings are arranged between every two adjacent pump casings.

And a threaded connection section is arranged between the check valve body and the pump body.

The multiple groups of pump shells are divided into at least three groups, and a middle bearing body is arranged between every two adjacent groups.

The two end parts of the connecting sleeve are in threaded connection with the check valve body and the water inlet section, and an anti-rotation screw is arranged at the joint.

One end of the pump shaft is connected with the water inlet section through the coupler, and the end part of the pump shaft penetrates out of the water inlet section.

Compared with the prior art, the utility model discloses the beneficial effect who has is:

Drawings

Fig. 1 is a schematic structural diagram of a high-lift submersible pump.

The anti-rotation pump comprises a check valve body 1, a check valve body 2, a threaded connection section 3, a connecting sleeve 4, a middle bearing body 5, a pump shaft 6, a pump shell 7, an impeller 8, a water inlet section 9, an anti-rotation screw 10 and a coupler.

Detailed Description

Fig. 1 is a preferred embodiment of the present invention, and the present invention will be further explained with reference to fig. 1.

Referring to figure 1: the utility model provides a high-lift immersible pump, includes the contrary valve body 1, the pump body, the section 8 and the pump shaft 5 of intaking that connect in order, and the pump body includes that the multiunit axial concatenates pump case 6 on the pump shaft 5, all assembles a set of impeller 7 alone in every pump case of group, at a set of adapter sleeve 3 of the outside suit of multiunit pump case 6, connects contrary valve body 1 and the section 8 of intaking respectively through adapter sleeve 3's both ends.

The multiple groups of pump shells 6 are clamped and fixed on the pump shaft 5 through steps arranged on the outer edge, and a sealing ring is arranged between every two adjacent groups of pump shells 6. A threaded connection section 2 is arranged between the check valve body 1 and the pump body. The pump shells 6 are divided into at least three groups, and a middle bearing body 4 is arranged between two adjacent groups. The two ends of the connecting sleeve 3 are in threaded connection with the check valve body 1 and the water inlet section 8, and an anti-rotation screw 9 is arranged at the joint. One end of the pump shaft 5 is connected with the water inlet section 8 through a coupler, and the end part penetrates out of the water inlet section 8.
