Gear Pump: Concept and Application
Abstract
Gear pumps are versatile, durable, and reliable machines that are used to transfer fluids such as oil, fuel, and water, among many others. They are most often used in automotive, industrial, and home applications. This paper discusses the basic components and working principles of gear pumps, as well as the various types and applications.
Introduction
A gear pump is a type of positive displacement pump that transfers fluids such as oils, fuels, and water. They are renowned for their high levels of durability and versatility, as they can be used in a wide range of applications including automotive, industrial, and home applications. The purpose of this paper is to discuss gear pumps in more detail and to provide an overview of the various types available, their working principles, and their various applications.
Types of Gear Pumps
Gear pumps can be divided into two basic categories, external and internal. External gear pumps are typically used to transfer large amounts of fluid, whereas internal gear pumps are better suited for pumping smaller amounts of fluid.
External gear pumps are made up of two gears, one of which is a spur gear and the other is an internal gear. As these gears rotate, the spur gear creates suction, drawing in the pumped fluid, and the internal gear forces the fluid out to the outlet port. This type of pump is typically used in automotive applications due to its high efficiency and its ability to provide a consistent output pressure.
Internal gear pumps are similar to external gear pumps, but the internal gear is the only gear visible in the pump. These pumps use a principle known as the oscillating pin which creates a wave of pressure within the pump. A small wedge-shaped pin is located between the internal gear and the pump housing, and as the gears rotate, the pin oscillates rapidly back and forth, creating a wave of pressure that draws fluid into the pump and forces it out. This type of pump is typically used in industrial applications where consistent output pressure is not required.
Working Principle
The working principle of a gear pump is based on the concept of positive displacement. As the two gears rotate in opposite directions, they create a wave of pressure which draws in the pumped fluid and then forces it out through the outlet port. The pressure created within the pump is dependent on the size and speed of the gears, as well as the size of the inlet and outlet ports.
Gear pumps are typically used in applications where low pressure and consistent output pressure are required. This makes them ideal for industrial applications such as oil and water pumps, fuel pumps, and power steering systems for cars.
Applications
Gear pumps are used in a wide variety of applications, from automotive to industrial to home applications. In automotive applications, gear pumps are typically used for power steering systems, fuel pumps, and oil pumps. In industrial applications, gear pumps are commonly used for transferring, controlling, or dispensing a variety of liquids, including industrial lubricants, fuel, and water. Gear pumps can also be used in home applications such as aquariums, where they are used to accurately and consistently pump water from one location to another.
Conclusion
Gear pumps are one of the most versatile and reliable pump designs available. They are used in a wide variety of applications and can be used to transfer large or small amounts of fluid. Gear pumps are most commonly found in automotive, industrial, and home applications, and are known for their durability and accuracy. Furthermore, they are highly efficient and can provide a consistent output pressure.
