Preferred technical solution is side and the pump housing inlet inner wall clearance fit of the deflector.Deflector and pump
Relative motion is not present between body inlet, crystal accumulates in the flatness for being additionally aided in above-mentioned gap and increasing deflector, keeps away
Exempting from the pre- spin of fluid makes deflector distort, and ensures water conservancy diversion effect.
Preferred technical solution is that deflector includes the first deflector and the second water conservancy diversion positioned at the first deflector both sides
The free end of plate, free end and the pump shaft clearance fit of the first deflector, the second deflector extends to below the side of pump shaft.The
Two deflectors extend to and can reduce the fluid of water conservancy diversion pump shaft section below below the side of pump shaft and prewhirl, and make pump operation best
Operating mode.
In order to simplify the structure of installation part, reduce resistance of the installation part for fluid feed, preferred technical solution is to pacify
Piece installing includes cylinder and flange, and the two sides of deflector are fixedly connected with the inner surface of cylinder, and deflector protrudes from the one of cylinder
End setting, flange are fixed at the other end outer rim of cylinder.Flange is directly placed at by bolt or flange in inlet
On the ladder-like boss of wall, latter situation realizes the fixation of installation part using the end face top pressure of inlet tube in pump housing inlet.
Preferred technical solution is that the outer surface of cylinder and the inner surface of pump housing inlet fit.In practical structures, pump
The inlet of body is wealthy mouth shape, the outer surface of cylinder and the inner surface of pump housing inlet fit can increase cylinder and the pump housing into
Stiction between liquid mouth, makes flow-guiding structure fix, prevent because fluid prewhirl so that deflector is rotated the phenomenon that.
In order to enhance the stability of conducting element structure, preferred technical solution is the junction setting of cylinder and deflector
There are reinforcing rib, the reinforcing rib to extend to the free end of deflector.
The advantages of the utility model and advantageous effect are：
The improved evaporation forced circulation pump is reasonable for structure, installs conducting element by using inlet, and in the prior art
Conducting element compare, above-mentioned conducting element is easy for installation, and the cleaning treatment for removing crystallization is also faster.
