Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is further described:

[0021] as attached figure 1 As shown, a reverse osmosis seawater desalination booster pump is used in the seawater desalination device of the reverse osmosis process to be precise. A water pump mainly includes a pump body 4, a pump cover 5, a pump shaft 9, an impeller 3, an impeller nut 1, a front seal ring 2, a mechanical seal 7, a tandem bearing 10, a positioning bearing 11, a bearing box and a bearing box cover. The connection relationship between the pump body 4, the pump cover 5, the pump shaft 9, the impeller 3, the impeller nut 1, the front sealing ring 2, the mechanical seal 7, the series bearing 10 and the positioning bearing 11, the bearing box and the bearing box cover is compared with the existing The technology is the same, so I won’t go into details here. It is characterized in that the end surface of the pump cover 5 relative to the rear end of the impeller 3 is...

Abstract

The invention discloses a reverse osmosis sea water desalination booster pump which mainly comprises a pump body, a pump cover, a pump shaft, an impeller, an impeller nut, a front sealing ring, a mechanical seal, a series connection bearing, a locating bearing, a bearing box and a bearing box cover. The reverse osmosis sea water desalination booster pump is characterized in that a hydraulic film carrying surface is arranged on the end face, opposite to the rear end of the impeller, of the pump cover, a high-pressure drainage hole is formed in the side wall of the pump cover in the radial direction, and hydraulic pressure-bearing grooves are formed in the circumference of the hydraulic film carrying surface in an array mode; hydraulic distributing holes are formed in the end faces of the hydraulic pressure-bearing grooves in the axial direction, one end of each hydraulic distributing hole is communicated with the corresponding hydraulic pressure-bearing groove, and the other end of each hydraulic distributing hole is communicated with the high-pressure drainage hole. The reverse osmosis sea water desalination booster pump has the advantages of being novel in structure, stable in performance, high in bearing capability, free of fracture surface contact, low in abrasion loss, balanced in axial force and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering pumps, in particular to a reverse osmosis seawater desalination booster pump. Background technique [0002] At present, the reverse osmosis seawater desalination device is a device for supplementing the pressure loss of the energy recovery device. The reverse osmosis seawater desalination device mainly exchanges liquid with seawater through a booster pump. Seawater desalination has become a strategic choice to solve the crisis of freshwater resources in the new century. my country's water resources are relatively short and unevenly distributed, and there is a huge demand for seawater desalination. Reverse osmosis technology has the advantages of simple process, convenient operation, easy automatic control, no pollution, and low operating cost. It is an advanced, stable and effective seawater desalination technology today. As the key equipment of the reverse osmosis seawater desalin...
