Vertical centrifugal pumps play a crucial role in the transportation of various liquids in the industrial field and can be found in industries such as chemical engineering, energy, and water conservancy.
The shaft of a vertical centrifugal pump is vertically oriented, and the shaft design comes in two types: radial split and overhung. For a single-stage vertical centrifugal pump, the inlet and outlet diameters are the same and are on the same centerline. It can be directly installed in the pipeline just like a valve, which saves a great deal of space. In some cases, the impeller is directly mounted on the extended shaft of the motor, reducing the overall length of the pump. In a multi-stage pump, there are two or more impellers on the shaft, and the heads generated by each impeller are added together, enabling the liquid to be transported to a higher and farther place.
After starting the pump, the motor drives the impeller to rotate rapidly. The liquid, under the action of centrifugal force, is thrown from the center of the impeller to the surroundings along the flow channels between the blades, increasing both its speed and pressure. In a single-stage pump, after passing through the volute (discharge chamber), most of the kinetic energy is converted into pressure energy, and then the liquid is discharged. In a multi-stage pump, the liquid enters the next-stage impeller through the diffuser channel, making the pressure gradually increase.
This type of pump is small in size and takes up little space, which can save a significant amount of construction costs. Mechanical seals are commonly used for the shaft seals, and with the use of wear-resistant materials such as imported titanium alloy sealing rings, the mechanical seals are more durable. The impeller and the pump casing are mostly made by stamping stainless steel, and the internal flow channels are very smooth. The bearing bushes and sleeves are made of hard alloys, which not only have a long service life but also will not contaminate the transported liquid. It is very suitable for transporting liquids such as clean water.
It is manufactured by referring to advanced technologies at home and abroad. It uses a standard vertical motor and is equipped with a quick-install mechanical seal, which is very easy to replace. Most of the parts in contact with the liquid are made of stainless steel, enabling it to transport liquids with slight corrosiveness. This type of pump is small in overall size and low in noise. The inlet and outlet are on the same horizontal line of the pump base and can be directly connected to the pipeline, making maintenance and inspection very convenient.
The greatest advantage of vertical centrifugal pumps is space saving. Compared with horizontal centrifugal pumps, they occupy much less space, making them very suitable for places with limited space. Some of them, with protective covers added, can be directly used outdoors, and the installation methods are very flexible. The bearing design of the pump and the motor is reasonable, which can balance various forces generated during operation, making the operation extremely stable with almost no vibration and noise. Moreover, the key components are made of wear-resistant and corrosion-resistant materials, making them more durable and reliable.
Due to the diversity of materials and structures, vertical centrifugal pumps can adapt to various working environments and different transported media. In the chemical engineering industry, they are responsible for transporting corrosive liquids. In water conservancy projects, with the characteristics of large flow rate and high head, they can achieve long-distance water transportation. In the environmental protection field, they help with wastewater treatment and sludge dewatering, greatly improving the treatment efficiency.
