The QH curve, also known as the pump performance curve, illustrates the relationship between the head generated by the pump and the flow rate. Head, typically measured in meters of liquid column. In the case of a centrifugal pump, as depicted in the chart, an increase in flow rate leads to a decrease in head.
A screw conveyor is a versatile and efficient material handling equipment used in various industries to move bulk materials horizontally or at an incline. Sizing the drive for a screw conveyor is crucial to ensure smooth operation and optimal performance. The drive unit plays a significant role in powering the screw conveyor and determining its capacity. In this article, we will discuss the recommended location for the drive unit, the components of a screw conveyor, and how to properly size the drive for a screw conveyor.

Recommended Location for the Drive Unit
The recommended location for the drive unit is on the discharge end of a screw conveyor. Placing the drive unit at the discharge end allows the conveyor to pull the bulk material towards the drive end, ensuring efficient material handling. With this arrangement, each screw section is put in tension, resulting in better control and stability during operation.
Screw Conveyor Size Chart
When sizing a drive for a screw conveyor, it is essential to refer to a screw conveyor size chart. This chart provides valuable information on the capacity, speed, and horsepower requirements based on the screw diameter and length. By using a screw conveyor size chart, you can accurately determine the appropriate drive size for your specific application.
Screw Conveyor Parts Diagram
A screw conveyor consists of various components that work together to transport materials. A screw conveyor parts diagram typically includes the following elements:
1. Inlet and Outlet: The points where the material enters and exits the conveyor.
2. Screw Shaft: The rotating shaft that moves the material along the conveyor.
3. Trough: The casing that houses the screw shaft and contains the material being transported.
4. Bearings: Support the screw shaft and allow for smooth rotation.
5. Drive Unit: Powers the screw conveyor and controls its movement.
Understanding the parts of a screw conveyor is essential when sizing the drive unit to ensure all components work harmoniously.
Schematic Diagram of Screw Conveyor
A schematic diagram of a screw conveyor provides a visual representation of how the conveyor operates. It illustrates the flow of material through the conveyor, the positioning of the drive unit, and the interaction between the various components. By referring to a schematic diagram, you can better understand the functionality of a screw conveyor and determine the appropriate drive size for your application.
Screw Conveyor Design Diagram
The design of a screw conveyor is critical in determining its performance and efficiency. A screw conveyor design diagram outlines the specifications, dimensions, and operating parameters of the conveyor. It includes details such as the screw diameter, pitch, speed, and capacity, which are essential factors to consider when sizing the drive unit. A well-thought-out design diagram ensures that the screw conveyor operates optimally and meets the requirements of the application.
Screw Conveyor Catalogue
Consulting a screw conveyor catalogue is a valuable resource when selecting a drive for a screw conveyor. A catalogue provides a comprehensive list of available screw conveyor models, along with their specifications and features. By reviewing different options in the catalogue, you can choose a drive unit that best suits your material handling needs. Additionally, a catalogue may offer recommendations on drive sizing based on the type of material, conveyor length, and operating conditions.
Screw Conveyor Data Sheet
A screw conveyor data sheet contains essential information about the conveyor system, including technical specifications, performance data, and design parameters. When sizing a drive for a screw conveyor, it is crucial to review the data sheet to understand the requirements of the application. The data sheet typically includes details such as material type, bulk density, conveyor length, and capacity, which are necessary for selecting the appropriate drive unit.
Screw Conveyor Diameter
The diameter of the screw conveyor plays a significant role in determining the size of the drive unit. A larger diameter screw conveyor requires more power to operate efficiently, while a smaller diameter conveyor may have lower horsepower requirements. When sizing the drive for a screw conveyor, it is essential to consider the diameter of the screw and its impact on the overall performance of the conveyor system.

A screw fitted directly to a hopper upstream is often referred in the literature as …
Few assets in a facility are as critical but also maintenance-intensive as centrifugal pumps, which is why so many applications use multiple-unit installations for backup. . If these conditions persist, any pump will fail prematurely. Emerson offers state-of-the-art monitoring and protection software that provides online vibration and bearing .
