Irrigation Double Suction Water Pump

Name: Irrigation Double Suction Water Pump Manufacturers and Factory China - Price List - DEPUMP
Brand: DEPUMP
SKU: 155362722

The Irrigation Double Suction Water Pump has the characteristics of high lift and large flow, and is widely used in engineering. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow can be doubled under the same outer diameter of the impeller; the pump casing is split horizontally, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which facilitates the arrangement and installation of the pump and the water inlet and outlet pipes.

^{The Advantages of Irrigation Double Suction Water Pump}

1. High Efficiency

Irrigation Double Suction Water Pump adopts the staggered arrangement structure of the two half impeller blades, thereby changing the blade frequency (the frequency of the blade passing through the tongue of the pump body), so that the liquid flow pulse is reduced (about 1% to 4‰ of the head reduction), the liquid flow is more stable, the efficiency is higher, and the vibration is more Smaller, more stable and reliable operation.

2. Low NPSH

For Irrigation Double Suction Water Pump, the shape of the inlet edge of the blade adopts a convex arc optimization design, which increases the flow area of the liquid inlet and reduces the inlet flow rate, which increases the inlet side pressure, thereby increasing the cavitation margin. The blade head adopts the airfoil streamline design, which reduces the impact loss of the liquid flow and reduces the vortex, which not only improves the highest point efficiency value, but also makes the high efficiency zone wider, uniform pressure distribution, and better cavitation performance.

3. High Reliability

Irrigation Double Suction Water Pump adopts a double volute design. The pump body and pump cover are equipped with stiffeners, and the ANSYS mechanical analysis software is used to optimize the structure. The pump has high strength. The pump casing hydraulic test is strictly in accordance with GBlT5656 "Centrifugal Pump Type II Technology" The water pressure test standard in Conditions is implemented. The thickened design of the short shaft of the bearing span makes the rotor less disturbed and stable and reliable during operation. All impellers are subjected to a class 6.3 static balance test, and the entire rotor is subjected to a class 2.5 dynamic balance test according to the AP1610 standard. The main shaft adopts a fully sealed design that does not contact liquids. The bearing parts are equipped with a lip-shaped oil seal + v-shaped seal ring combined sealing structure, which has excellent oil leakage, dust, water, and moisture resistance functions.

4. Strong Adaptability

The pump has a wide high efficiency area, which can meet user requirements in a wider range; in addition, the pump adopts a one-pump two-wheel impeller configuration method, which makes the pump very selectable, which can ensure that most of the user's working conditions can be selected to be highly efficient Scope. The pump inlet and outlet flanges can be processed in accordance with GB, ISO, DIN, BS, ANSI and other standards. Pump casing flow channel: Super-slip energy-saving coating, wear-resistant and corrosion-resistant coating can be selected. The CPS-R structure can be used to transport high-temperature media, and the pump adopts a central support, water-cooled bearing body. Shaft seal system: It can realize the interchange of packing seal and single end face seal, and can also be equipped with container mechanical seal, double end face mechanical seal and AP1682 standard flushing system according to user requirements. Bearing lubrication system: Grease lubrication or thin oil lubrication can be used for flexible selection. Bearing cooling system: The bearing body can be cooled by natural cooling or water cooling according to the temperature of the medium.

5.High Generalization

Except for a few parts such as pump body, pump cover, impeller, etc., all other parts adopt modular design, which realizes standardization of parts. Coaxial bearing parts, sealing parts, shaft sleeves, stop sleeves, etc. can be interchanged for easy realization Mass production of pumps.
