Abstract
The utility model relates to the field of electromechanical devices, in particular to a centrifugal pump. An internal recycle cooling clean water centrifugal pump comprises a pump body, a pump cover, an impeller, an impeller shaft and a pump seat. The pump cover covers the pump seat in a sealing mode. The pump body is arranged on the pump cover. One end of the impeller shaft is supported on an axial bearing in the pump seat and is used as a transmission end. The other end of the impeller shaft extends out of the pump cover and is used as a cantilever end. The impeller is arranged at the cantilever end. A shaft sleeve and a supporting bearing are arranged between the impeller shaft and the pump cover and are sealed through a sealing mechanism. A water inlet is formed at the front end of the pump body, and a water outlet is formed in the upper portion of the pump body. A cooling circulation tube is arranged at the axis of the impeller shaft and is a double-layer sleeve. The outer layer of the cooling circulation tube is a water inlet path and is communicated with the water outlet. The inner layer of the cooling circulation tube is a water outlet tube and is communicated with the water inlet. The double-layer cooling water circulation sleeve is arranged at the axis of the impeller shaft of the internal recycle cooling clean water centrifugal pump, and no extra cooling water pipelines need arranging, so that the service life of the impeller shaft is prolonged.
Description
Technical field
The utility model relates to the electromechanical equipment field, relates in particular to a kind of centrifugal pump.
Background technique
Pump is the machine of carrying liquid and improving fluid pressure.Pump is divided into chemicalpump, water pump, air pump etc., and Main Differences is special material and design, prevents corrosion and adapts to chemical process, comprises structure, shaft seal, material and maintenance difficulty.In water pump, with being most widely used of centrifugal pump, centrifugal pump, when work, relies on the impeller of High Rotation Speed, and liquid has obtained energy to have improved pressure under the inertial centrifugal force effect.When the impeller quick rotation, blade impels medium to rotate very soon, and the medium rotated is from impeller, flying out under the effect of centrifugal force, and after the water in pump was dished out, the core of impeller formed vacuum area.One side constantly sucks liquid, and the certain energy of liquid that one side constantly sucks again, discharge liquid.Centrifugal pump is just so continuously worked.Existing centrifugal pump when work impeller and the impeller shaft friction area of front end by the circulating liquid in pump itself, undertaken cooling, but the part that the impeller shaft rear end contacts with pump just has any cooling method, when wheel speed is higher, this regional impeller shaft just is easy to wearing and tearing, has affected the working life of impeller shaft.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of interior circulating cooling water purification centrifugal pump, and the impeller shaft axle center of this water pump is provided with the cooling water circulation sleeve pipe of a bilayer, without the extra cooling water pipeline of arranging, simple in structure, cost is low.
The utility model is achieved in that a kind of interior circulating cooling water purification centrifugal pump, comprise the pump housing, pump cover, impeller, impeller shaft and pump seat, described pump cover sealing cover is on pump seat, the described pump housing is arranged on pump cover, on the cod of one end bearing in pump seat of described impeller shaft as driving end, the impeller shaft the other end stretches out pump cover as cantilever end, and described impeller is contained on cantilever end, axle sleeve and spring bearing is housed between impeller shaft and pump cover and is sealed by sealing mechanism; The front end of the described pump housing offers water intake, the top of the pump housing offers water outlet, the axle center of described impeller shaft is provided with the cool cycles pipe, described cool cycles pipe is bilayer sleeve, the skin of cool cycles pipe is that inlet channel is communicated with water outlet, and the internal layer of cool cycles pipe is that outlet pipe is communicated with water intake.
