Stainless steel structural principle of the axial flow pump

stainless steel the principle of axial flow pump structure

stainless steel axial flow pump is low traffic, water pump head, high specific speed of vane pump, axial flow is the flow of fluid along the shaft bearing of liquidity, but the root of the planning ideas and centrifugal water pump roots together in the end. Stainless steel axial flow pump according to the installation methods of the main shaft bearing is the pillar type, vertical and lateral type 3 kinds.

1。 Water inlet horn tube

inlet horn tube for big small and medium-sized pillar type stainless steel the moisture absorption of axial flow pump room, made of cast iron production, its effect is to put the water to the harm of smaller symmetrically to the impeller. Fallopian tube import part of the circular arc shaped, in large and medium-sized stainless steel axial flow pump, the suction wet room generally made through the method of flow channel.

2。 Impeller

the impeller is the key component in the homework, composed of blades, wheel Hu, guide water cone, etc. Stainless steel blade of axial flow pump is distorted shape on the wheel Hu. According to the probability of blade scheduling mobile share out bonus, half scheduling and scheduling all three and a half scheduling impeller blade is necessary after shutdown and disassembling impeller, can begin scheduling. Total scheduling type blade is according to the mechanical equipment or hydraulic press a scheduling group to change the blade installation Angle.

3。 Guide vane

guide vane located on top of guide vane impeller tube, and fixed on the guide vane on the tube. The key of its success is to remove fluid mechanics of fitness, hydraulic gradient. Other fluid mechanics can be part of the mechanical energy can change for pressure.

4。 Shaft and bearing

big small and medium-sized axial flow pump shaft is solid core of stainless steel. Stainless steel axial flow pump bearings according to its role can share out bonus three categories: the axial bearing, bearing, and guide bearing. China merchants bearing used to bear radial force in the composition of pump operation in the whole process. Guide bearing in a diffuser cone, to reduce the shake shaft, the common material RunHua or guide bearing RunHua cleaning fluid.

5。 Stainless steel pump

seal axial flow pump according to the rules of using sites equipped with filling material or machine, similar to the centrifugal water pump water pump seal.

6。 body

stainless steel axial flow pump body is cylindrical, because there have a fixed guide vane, so the auteur vane pump body. Guide vane is installed behind the wheel, a cone-shaped, with double guide vane. Stainless steel axial flow out of the water is a bend. Big small and medium-sized stainless steel axial flow pump leakage, choose horn more short tube, and large and medium-sized stainless steel axial flow pump is more choose elbow bent or bell is leaking.
