Description
Technical field
The utility model relates to a kind of centrifugal pump, belongs to liquor pump technical field.
Background technique
The centrifugal force that centrifugal pump produces when being and relying on vane rotary, to carry the pump of liquid, utilizes the impeller blade of High Rotation Speed to drive water to rotate, is thrown away by water, thus reach the object of conveying.Due to centrifugal pump structure problem, often there will be Centrifugal Pump, lift is not enough, centrifugal pump seal leaks seriously, the phenomenons such as vibration or noise occur centrifugal pump.
Model utility content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of centrifugal pump.
Technological scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of centrifugal pump, comprise movable pump case, fixing pump case, support, impeller, gland seal device, motor, import, outlet, pump shaft, described import is arranged on movable pump case front end, described outlet is arranged on movable pump case top, described impeller is arranged in movable pump case, described Bracket setting is bottom fixing pump case, described motor is arranged in fixing pump case, described movable pump case is fixed on fixing pump case front end, described pump shaft is connected with motor front end through fixing pump case, described impeller is connected with pump shaft free end, described pump shaft and fixing pump case joint are provided with gland seal device.
Also comprise quick detach hoop, described movable pump case is flexibly connected with fixing pump case by quick detach hoop.
Described impeller is set to enclosed impeller.
Described gland seal device is set to stuffing seal.
Also comprise shock-absorbing spring, described shock-absorbing spring is arranged on bottom motor.
Preferably, described shock-absorbing spring quantity is set to two.
Beneficial effect: a kind of centrifugal pump that the utility model provides, by adopting enclosed impeller, can effectively improve lift and flow; Gland seal device ensure that sealing good between main shaft and the pump housing.The design's compact structure, flow and range of lift are wide, uniform flow, smooth running, vibration are little, it is good to be sealed performance.
