Embodiment

[0029] see figure 1 , image 3 , Figure 4 , Figure 5 , Figure 7 , the high-efficiency high-lift general-purpose well pump includes a guide casing 3, a pump shaft 4, and an impeller 6. The impeller 6 includes long blades, a rear cover plate and a front cover plate with a water inlet in the middle. It is characterized in that the impeller 6 also has Short blades are provided, and the short blades are located in the outer edge area of ​​the impeller 6, and between two adjacent long blades; the length ratio of the short blades to the long blades is 0.40--0.80:1; the long There are at least 3 leaves, and the ratio of long leaves to short leaves is 1:1, or 1:2 or more; or the long leaves are twisted leaves, and the short leaves are arc-shaped leaves. Or the long blades are arc-shaped blades, and the short blades are twisted blades. The long blades are twisted blades, and the short blades are twisted blades. A rubber bearing 2 is provided between the pump shaft 4 and the gu...

Abstract

The invention provides an efficient high-lift universal well pump and relates to the technical field of centrifugal submersible pumps. The universal well pump mainly comprises a pump bowl, a pump shaft and an impeller. The impeller comprises long blades, a rear cover plate and a front cover plate provided with a water inlet. Short blades are disposed on the impeller and located at the outer edge of the impeller and between two adjacent long blades. The long blades or the short blades are warped blades. The universal well pump has the advantages the potential of the pump is fully exploited and increased, the single-stage lift of the pump is increased greatly, the performance indexes such as efficiency of the pump are increased at the same time, materials are saved greatly, yield is doubled, cost is lowered greatly, benefits are increased by 5 times, high efficiency and energy conservation are achieved, application range of the pump is increased, and the pump is stable and reliable in operation, long in service life, small in size, lightweight, convenient to produce, sell, transport, mount, use and maintain.

Description

technical field [0001] The invention relates to the technical field of centrifugal submersible pumps, in particular to the innovation and improvement of the design of high-efficiency and high-lift universal centrifugal submersible single-stage and multi-stage well pumps. Background technique [0002] At present, the impeller blades of well pumps produced by manufacturers are generally long blades, whether they are arc-shaped blades (see attached Figure 6 ) or twisted blades (see attached figure 2 ), the number of blades is generally 4 to 7 pieces, the single-stage head of the pump is low, and the high-efficiency zone is narrow. There is a lot of potential to be tapped and needs to be further innovated and improved. Effectively improving the performance index of the well pump has been a hot topic to be solved in this industry for a long time, because the improvement of the performance index will bring significant economic benefits nationwide.
