Abstract
The utility model relates to the field of electromechanical devices, in particular to a centrifugal pump. A clean water centrifugal pump with an internally-arranged motor 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 in the front end of the pump body, and a water outlet is formed in the upper portion of the pump body. The motor is arranged in the pump seat. A cooling circulation pipeline bypassing the motor is communicated with the pump body. An output shaft of the motor is connected with the transmission end of the impeller shaft through a coupler. The internally-arranged motor is arranged on the pump body, and circulation fluid driven by the pump itself is utilized to cool the motor, so that cooling efficiency is improved. Meanwhile, the pump seat wraps the motor, so that noise generated by the motor is reduced.
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.The most motor of existing centrifugal pump is arranged on pump housing outside, so usually noise is larger, and cooling cooling by air natural, and efficiency is very low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water purification centrifugal pump of built-in motor, and the pump housing built-in motor of this water pump the circulation of fluid of utilizing pump self to drive are carried out cooling to motor, greatly improved cooling effectiveness.
The utility model is achieved in that a kind of water purification centrifugal pump of built-in motor, 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, and the top of the pump housing offers water outlet, in described pump seat, motor is housed, and on the described pump housing, is communicated with the cool cycles pipeline of walking around motor, and the output shaft of motor is connected with the driving end of impeller shaft by coupling.
On described impeller, have equalizing orifice.
Described spring bearing is ball bearing.
Described sealing mechanism is packing seal mechanism, consists of packing ring, Gland and filler three parts.
The described pump housing is spirality Crucible shell.
The water purification centrifugal pump of the utility model built-in motor is the back opening door centrifugal pump, pump housing built-in motor the circulation of fluid of utilizing pump self to drive are carried out cooling to motor, greatly improved cooling effectiveness, simultaneously because motor is enclosed in pump seat, so reduced the noise that motor sends.
