Factories Double Suction Split Case Pump inlet diameter of 250mm

Uses:

The double suction pump is also known as a single-stage double suction centrifugal pump, the main feature for the transmission medium flow, mainly for factories, cities, Power stations, water conservancy projects, irrigation and other drainage or water supply pump. The transport of solid particles can not exceed the diameter of 10mm, the content can not exceed 5%.

【Product description】

Double suction in the pump is also known as a single-stage double suction centrifugal pump, the main feature of the transmission medium flow, head, in the open pump operation principle: impeller installed in the pump shell and fastened to the pump shaft On the pump shaft directly driven by the motor. There is a liquid suction in the center of the pump housing connected to the suction pipe.

Wei-pump production of the double suction pump is a horizontal centrifugal pump, the type of pump with a flow range than the IS-wide, the head is not very high characteristics, mainly for factories, cities, power plants, water conservancy projects, Farmland irrigation and other drainage or water supply pump. The transport of solid particles can not exceed the diameter of 10mm, the content can not exceed 5%. Pump delivery medium temperature can not exceed 80 ℃, the inlet pressure can not exceed 0.6Mpa.

【Structure Introduction】

The pump suction and discharge are in the pump under the axis of the axis, the horizontal direction and the axis into a vertical position, the pump shell open, maintenance without disassembly of water, discharge pipes and motors (or other prime movers) from the joint Shaft to the direction of the pump looked, the pump are clockwise rotation, the pump inlet on the right. Such as according to the user special order needs can also be changed counterclockwise rotation.

The main components of the pump, pump cover, impeller, shaft, double suction ring, sleeve, bearings and so on. In addition to the shaft material for high-quality carbon steel, the rest are made of cast iron. But according to the needs of the user axis can be changed to stainless steel, stainless steel and other material pump body and pump cover can also be.

The pump body and the pump cover constitute the impeller working chamber, in the inlet and outlet of the flange on the installation of the vacuum gauge and pressure gauge pipe screw hole. The impeller is calibrated by static balance, fixed with the sleeve and the sleeve nuts on both sides. The axial position can be adjusted by the sleeve nut. The axial force of the impeller is balanced with its symmetrical arrangement of the blades, and there may be some remaining The axial force is the bearing of the coaxial end. The pump shaft is supported by two single row radial ball bearings, which are mounted on the bearing body at both ends of the pump body and lubricated with butter. The double suction seal ring is used to reduce the water in the pump water chamber.

The pump is directly driven by the motor through the coupling, the shaft seal is a soft packing seal, and the other material and mechanical seal can be used according to the different media. In order to cool the lubricating seal chamber and prevent the air from leaking into the pump, there is a water seal ring between the packing, and the water pump works with a small amount of high-pressure water flowing through the water seal tube into the packing chamber.
