Introduction:Internal gear pumps are widely used in the hydraulic pump industry due to their unique design and functionality. In this article, we will explore the purpose of internal gear pumps, their working principles, and their applications in various industries. Additionally, we will also introduce some popular products offered by the Poocca brand.
What are Internal Gear Pumps?
Internal gear pumps are positive displacement pumps that consist of an outer rotor with external teeth and an inner rotor with internal teeth. The gears mesh together, creating chambers that trap and transport fluid from the inlet to the outlet. These pumps are known for their high efficiency, reliability, and compact design.
Working Principles of Internal Gear Pumps
When the pump is in operation, the rotation of the gears creates a partial vacuum at the inlet, causing fluid to be drawn into the pump. As the gears continue to rotate, the fluid is trapped in the chambers between the gear teeth and is carried to the outlet. The meshing of the gears ensures a continuous flow of fluid without any pulsations.
The composition of hydraulic internal gear pump
The hydraulic internal gear pump consists of two main gears, one is the outer gear (driving gear) and the other is the inner gear (driven gear). The inner gear is located inside the outer gear, and the two are coaxial, but the inner gear is smaller than the outer gear and has fewer teeth. There is also a fixed crescent-shaped partition in the pump body to separate the oil inlet and the oil outlet
Engagement and movement
When the driving gear rotates, the gears between the inner and outer gears begin to mesh and separate.On the oil inlet side, when the gears separate, an increased volume is formed, a vacuum is generated, and the hydraulic oil is sucked in.The hydraulic oil is carried to the oil outlet side by the rotation of the gears.When the gears mesh on the oil outlet side, the volume between the gears decreases, and the hydraulic oil is squeezed out, thereby generating a hydraulic oil flow.
The role of the crescent-shaped partition
The role of the crescent-shaped partition is to prevent the hydraulic oil on the high-pressure side from flowing back to the low-pressure side, ensuring that the hydraulic oil can only flow from the oil inlet to the oil outlet.
Applications of Internal Gear Pumps
Internal gear pumps find applications in various industries due to their versatility and ability to handle a wide range of fluids. Some common applications include:
Hydraulic systems
Internal gear pumps are widely used in hydraulic systems for power transmission and control. They provide precise and reliable fluid flow, making them suitable for applications such as construction machinery, agricultural equipment, and material handling.
Industrial machinery
Internal gear pumps are used in industrial machinery for lubrication, cooling, and fluid transfer. They are commonly found in injection molding machines, bending machinery, and shearing machinery.
Automotive industry
Internal gear pumps are utilized in automotive applications for engine lubrication, transmission fluid circulation, and power steering systems. They offer efficient and reliable fluid transfer, ensuring optimal performance of the vehicle.
Oil and gas industry
Internal gear pumps are employed in the oil and gas industry for various processes, including crude oil transfer, refining, and petrochemical applications. Their ability to handle high pressures and corrosive fluids makes them suitable for these demanding environments.
