What Is The Theory Of Peripheral Pump?

Introduction

Peripheral pumps are essential in pumping water in residential, commercial, and agricultural facilities. It''s important to understand the theory behind these pumps to effectively choose, install, and maintain them. In this article, we''ll explore the theory of peripheral pumps and their workings.

What is a Peripheral Pump?

A peripheral pump is a type of centrifugal pump that is also known as a side-channel pump. The impeller of the pump is positioned in a peripheral position in relation to the pump''s volute casing. This type of pump operates through the centrifugal force generated when the impeller rotates. The rotation of the impeller creates a vortex that is filled with liquid, which is then delivered to the discharge pipe of the pump.

How Does It Work?

A peripheral pump works by using an impeller that rotates rapidly to create a centrifugal force. This force creates a vacuum at the center of the impeller, which draws water into the pump''s inlet. As the water enters the pump, it''s thrown outward by the centrifugal force, and it''s redirected by the casing back to the impeller again. The cycle repeats, and the water keeps being thrown outward and redirected inward. This results in the water being lifted and pushed out of the pump''s outlet with pressure.

Advantages of Peripheral Pumps

Peripheral pumps are generally economical and easy to maintain, making them a great choice for domestic and small commercial applications. Some of the key advantages of peripheral pumps include:

1. Easy maintenance and repair
2. Low noise level during operation
3. Energy-efficient
4. Suitable for low pressures and flow rates

Disadvantages of Peripheral Pumps

Despite the benefits of peripheral pumps, they also have some disadvantages to consider. These include:

1. Limited suction power
2. Not suitable for high-pressure applications
3. Not as durable as other types of pumps
4. Susceptible to damage from abrasives in the water being pumped

Factors to Consider When Choosing a Peripheral Pump

When selecting a peripheral pump, there are several factors to consider, including:

1. Flow rate: The higher the flow rate, the higher the power requirements for the pump.
2. Pressure: The pressure requirement will depend on the application and the diameter of the pipes being used.
3. Motor power: The motor power required will depend on the flow and pressure requirements of the application.
4. Material: The material of the pump should be able to withstand the liquid being pumped with regard to temperature, acidity levels, and any abrasiveness.
5. Volume of water: The volume of water being pumped should also be considered.

Installation and Maintenance

Proper installation and maintenance are essential for the reliable and efficient operation of peripheral pumps. Here are some key installation and maintenance tips to keep in mind:

1. Proper installation: Make sure the pump is installed in a clean and dry environment, and follow the manufacturer''s instructions.
2. Regular inspection: Regularly inspect the pump for any signs of damage or wear and tear.
3. Lubrication: Ensure that the bearings are lubricated regularly, as this will help prevent friction and extend the life of the pump.
4. Impeller cleaning: Keep the impeller clean, removing any buildup or debris that might accumulate over time.
5. Electrical wiring: Make sure the electrical wiring is secure and in good condition to prevent any short circuits.

Conclusion

Peripheral pumps are an efficient and cost-effective choice for a wide range of domestic and commercial applications, but a good understanding of their theory and workings is essential for installation, maintenance, and their efficient use. When selecting and installing a peripheral pump, take the time to consider the various factors mentioned in this article. With proper installation and maintenance, a peripheral pump can provide reliable service for many years.
