A high-lift bulb tubular pump

Abstract

The invention discloses a high-lift lamp bulb tubular pump which comprises a water inlet runner, an impeller chamber, a back flow guide body and a water outlet runner which are sequentially, coaxiallyand fixedly arranged in the water flow direction. An impeller is arranged in the impeller chamber, the impeller comprises a hub and a plurality of equal-thickness impeller blades installed on the hub, the hub and the impeller chamber are concentric hemispheres, and the hub and a pump main shaft are connected; the back flow guide body comprises an outer cover, an inner cover and fixed guide blades; the outer cover is coaxially arranged on the periphery of the inner cover in a sleeving manner, and the outer cover is in a bell shape; and the fixed guide blades are arranged between the inner cover and the outer cover in an inclined manner. The water outlet runner is internally provided with a lamp bulb body fixed in position, the lamp bulb body and the inner cover are coaxially arranged, thehead of the lamp bulb body is fixedly connected with the water outlet side of the inner cover, and the tail of the lamp bulb body is oval. When the high-lift lamp bulb tubular pump is used in the liftscope of 7 m-10 m, the impeller efficiency can reach 90%, and the water flow state and unit output can be better guaranteed. The novel equal-thickness blades are adopted, and therefore the tubular pump lift can be improved, machining is easy and convenient, input is reduced, and the market requirements are met.

Description

technical field [0001] The invention relates to the technical field of fluid machinery and pump station devices, in particular to a high-lift bulb tubular pump. Background technique [0002] Energy is the material basis of human activities. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technologies. With the rapid development of modern society and economy, human's demand for energy is increasing rapidly. At present, the fossil fuels used in large quantities are limited non-renewable energy sources, and the fossil fuels have been gradually exhausted. At the same time, the extensive use of fossil fuels has caused increasingly serious environmental pollution. In today's world, the development of energy, energy and the environment are issues of common concern to the whole world and all mankind. [0003] my country's water resources are very rich, ranking first in the world. A water pump i...
