Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the utility model:
The utility model discloses a kind of express pumps with self-cleaning function.Express pump is also known as Force of High Speed Partial Flow Pump,
Belong to one kind of centrifugal pump.The basic functional principle of express pump is similar with Ordinary Centrifugal Pumps, except that utilizing gearbox
Accelerating function makes running wheel obtain the working speed for being several times as much as Ordinary Centrifugal Pumps impeller, it is increased using wheel speed is improved
The fluid linear velocity on impeller outer edge, achievees the purpose that high lift.Express pump is made of motor, speed increaser and pump three parts.This
Utility model is improved on the basis of existing express pump, is convenient for being cleaned.Here is specific
Embodiment:
The express pump with self-cleaning function of the utility model, as shown in Figure 1 and Figure 2, including the pump housing 1, end setting master
The drive shaft 4 and driving motor 3 of impeller 2.Drive shaft 4 is used to that main impeller 2 to be driven to carry out the conveying that medium is realized in rotation.Main lobe
Wheel 2 is arranged in the pump housing 1, and the pump housing 1 has medium entrance 1-1 and media outlet 1-2.The other end closed at one end of the pump housing 1
Pump cover 7 is set.Setting is used for the gear-box 8 of step-up drive between the output shaft and drive shaft 4 of driving motor 3.Pass through gear
The output revolving speed of driving motor 3 can be carried out speedup and reached so that drive shaft 4 be made to be able to drive 2 high speed rotation of main impeller by case 8
To the performance requirement of express pump.Further, frequency converter can also be set for driving motor 3, frequency conversion is set for driving motor 3
Device is the method for commonly being used to adjust 3 revolving speed of driving motor in the field.
The utility model further includes the cleaning impeller 5 being oppositely arranged with main impeller 2, and the cleaning impeller 5 is mainly needing
Use when being cleaned to express pump.Cleaning impeller 5 is fixed on one end of shaft 6, and the shaft 6 is hinged on the closing of the pump housing 1
It holds and extends to outside the pump housing 1.The end of shaft 6 can be connected with motor, and rotation is driven by motor, and need to clean high speed
When pump, make shaft 6 that cleaning impeller 5 be driven to rotate, while 2 industry of main impeller rotates, the two jointly acts on the water in the pump housing 1, makes
Water generates surge in the pump housing 1, to realize for the cleaning inside the pump housing 1.In specific implement, main impeller 2 and cleaning
Impeller 5 is disposed as turbine.In specific implement, preferential, setting main impeller 2 and the outer diameter for cleaning impeller 5 are in the same size
It is 15~20cm that the distance between main impeller 2 and cleaning impeller 5, which is arranged,.Specific structure is as shown in Figure 2.
The utility model as shown in Figure 1, Figure 2, Figure 3 shows, usually goes out medium entrance 1-1 and medium in specific implement
