Duwan Environmental LS80-44AThe installation technique for vertical pipeline centrifugal pumps is crucial in determining the pump's installation height, also known as the suction head. This height refers to the vertical distance from the water surface to the centerline of the pump's impeller.
It should not be confused with the allowable suction vacuum height; the allowable suction vacuum height indicated on the product manual or label of the pump refers to the vacuum value at the pump's intake port cross-section.
And it was tested and determined under standard atmospheric pressure of 1 and water temperature of 20°C. It did not take into account the water flow conditions after the water intake pipeline is matched.
The pump installation height should be the remaining value after deducting the head loss of the suction pipe from the allowable suction vacuum height.
To overcome the actual terrain's water absorption height. The pump installation height must not exceed the calculated value; otherwise, the centrifugal pump will not be able to pump water.
Additionally, the size of the calculated value is affected by the head loss due to the resistance of the suction pipeline, thus, it is advisable to use a shorter pipeline layout and minimize the installation of bends and other accessories.
Consider using larger diameter pipes to reduce flow velocity inside the pipes. It should be noted that the elevation and water temperature at the installation location of the vertical pipeline centrifugal pump are different from the test conditions.
If the local altitude is above 300 meters or the water temperature exceeds 20°C, the calculated value requires adjustment.
At different elevations and at water temperatures above 20°C, the atmospheric pressure and saturated vapor pressure.
However, the saturated steam pressure can be ignored when the water temperature is below 20℃.
In terms of pipeline installation technology, suction pipelines require strict sealing.
No leakage of air or water, otherwise it will destroy the vacuum degree at the centrifugal pump's intake, reducing the water output of the centrifugal pump.
Severe cases may even result in no water being pumped. Therefore, it is crucial to meticulously handle the pipeline joints to ensure the construction quality of the pipe connections.
I. Different Structures:
Vertical centrifugal pump, a centrifugal pump designed for vertical structure. Similarly, the horizontal centrifugal pump is also a centrifugal pump that is literally designed for horizontal structure.
II. Different Applications:
Vertical centrifugal pump: Used for conveying clean water and other liquids with similar physical and chemical properties to clean water. Suitable for industrial and urban water supply and drainage, high-rise building pressure boosting, garden sprinkling, fire fighting pressure boosting, long-distance transportation, HVAC refrigeration cycle, bathroom, and other cold and hot water circulation pressure boosting and equipment matching. Service temperatureT<80℃。
Horizontal Centrifugal Pump: Designed for transporting liquids without solid particles, corrosive in nature, and having a viscosity similar to water, suitable for industries such as oil, chemical, metallurgy, power, papermaking, food, and synthetic fibers, with operating temperatures-20℃ to 120℃.
III. Different Connection Forms:
Vertical pumps are connected in an ascending stack from bottom to top, while horizontal pumps are arranged longitudinally from left to right on the base.
Four: Varying Space Requirements:
Vertical centrifugal pumps, due to their vertical structure, require less space in terms of footprint. In contrast, horizontal centrifugal pumps, being horizontally structured, occupy significantly more space than vertical pumps.
V. Different Installation Styles:
Vertical and horizontal structures differ in their installation methods. For instance, vertical pumps are a single assembly and are very easy to install. In contrast, horizontal pumps require precision adjustment after installation.
Six: Varying Repair Difficulty
Vertical pump maintenance is challengingIf wheel inspection is required, the entire upper section must be removed to proceed; however, horizontal pumps are relatively easier, as with the IS type pump, the impeller maintenance can be carried out by simply removing the inlet pipe.
