  • Detail

Fuyang pump sh double suction pump is favored by the market because of its unique structural advantages. As an important form of centrifugal pump, SH double suction pump is widely used in the market because of its unique structural advantages. "Fuyang pump sh double suction pump has become the leader of many sh double suction pumps because of its unique structural advantages." Mr. Wang of Fuyang pump said so

as an important form of centrifugal pump, SH double suction pump is widely used in the market by virtue of its unique structural advantages. "Fuyang pump sh double suction pump has become the leader of many sh double suction pumps by virtue of its unique structural advantages." Mr. Wang of Fuyang pump said so

according to Mr. Wang, the so-called SH type double suction pump is a single-stage, double suction, split casing centrifugal pump, that is to say, SH type double suction pump is a kind of centrifugal pump and an important form of centrifugal pump. SH type double suction pump is mainly used to transport clean water and liquids with physical and chemical properties similar to water. It is widely used in projects, such as mines, urban water supply, power stations, large-scale water conservancy projects, farmland irrigation and drainage. Next, take the SH double suction pump produced by Fuyang pump industry as an example to introduce the structural characteristics of this kind of pump

detailed explanation of SH double suction pump structure of Fuyang pump

sh double suction pump main parts include pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve, bearing body, etc. Mr. Wang introduced that except that the shaft is made of high-quality carbon steel, the rest are mostly made of cast iron

sh double suction pump body: it forms the working chamber of the impeller with the pump cover, and the flanges of the inlet and outlet channels are provided with pipe screw holes for installing vacuum gauges and pressure gauges. The lowest pipe diameter is provided with a pipe screw hole for water drainage

sh screw rod double suction pump cover: pipe screw holes for installing water seal pipe and air inlet pipe and lifting hooks for lifting the pump are made on the upper part

sh double suction pump impeller: the shape is symmetrical, and there are twisted blades between the two walls. The liquid enters the impeller from both sides and passes the static balance test during manufacturing

inner diameter scale SH type double suction pump shaft: the center of the shaft is the impeller, which is fixed with keys, shaft sleeves and shaft sleeve nuts on both sides. The right end of the shaft is equipped with a coupling and is directly connected with the motor. Belt drive is not allowed at the coupling end. If belt drive is required, another bracket must be set to support the pulley

sh double suction pump double suction seal ring: prevent the high-pressure water in the pump from leaking back to the water inlet part. A raised semicircular ring is made on the double suction seal ring and embedded in the pump body. The double suction seal ring is fixed with the tensile property of Jinan assaying plastic and rubber as one of the most important and basic mechanical properties

sh double suction pump shaft sleeve: used to fix the impeller position and protect the shaft wear in the packing chamber

in addition, President Wang specially mentioned that the double suction seal ring and shaft sleeve of SH double suction pump are vulnerable parts, so more spare parts should be provided for replacement

unique structural characteristics of SH double suction pump of Fuyang pump industry

after introducing the structure of SH double suction pump, President Wang patiently explained the structural advantages of SH double suction pump to us. "The SH double suction pump produced by Fuyang pump industry has also been recognized by customers, and its structural advantages are very obvious." Mr. Wang said. Here are some structural advantages of SH double suction pump summarized by President Wang:

1. Sh double suction pump has compact structure, beautiful appearance and easy installation

2. The impeller of SH double suction pump is composed of two back-to-back impellers, which is equivalent to two single suction impellers with the same diameter working at the same time, and the flow can be doubled under the same impeller outer diameter

3. The pump casing is horizontally split, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft. At the same time, it also has high elongation and toughness, which is conducive to the layout and installation of the pump and inlet and outlet pipes

4. The optimized double suction impeller reduces the axial force to the minimum and has excellent hydraulic performance. After precision casting, the inner surface of the pump shell and the impeller surface are extremely smooth, with significant cavitation resistance and high efficiency, and the operation is relatively stable

5. Shaft seal: Burgmann mechanical seal or packing seal is selected to ensure no leakage during 8000 hours of operation

6. Bearing: SKF and NSK Bearings are selected to ensure stable operation, low noise and long service life

finally, I would like to thank Mr. Wang of Fuyang pump industry for introducing so much relevant knowledge about sh double suction pump to us, so that we have a deeper understanding of double suction pump. At the same time, we also hope Fuyang pump industry can persevere in the research, development and production of pumps and keep improving
