Working principle of low-noise circular arc gear pump

  Low noise circular arc gear pump is a special type of gear pump designed to reduce operating noise while maintaining high efficiency and reliable liquid transfer capacity.

Its core lies in the use of a unique circular arc tooth profile design, rather than traditional straight edge or involute shaped gears. The following is a detailed explanation of the working principle and advantages of a low-noise circular arc gear pump:

working principle:

1. * * meshing method * *: Two sets of circular arc gears mesh with each other, one of which is the driving wheel driven by an electric motor, and the other is the passive wheel that rotates synchronously with the driving wheel. The space between two gears inside the pump casing alternately closes and opens, forming a suction area and a discharge area.

2. Liquid suction and discharge: When the two gears separate, a suction chamber is formed where the liquid is sucked in; As the gear continues to rotate, the gradually shrinking space pushes the liquid towards the discharge port, completing the conveying process.

3. * * Smooth Flow * *: The special shape of the circular arc gear ensures that the contact lines between the gears always remain in contact without impact, reducing the turbulence and pressure pulsation of the medium, thereby reducing the noise level.

Advantages and Characteristics:

1. * * Low noise * *: The smooth meshing of the circular arc gear reduces the common "trapped oil" effect in traditional gear pumps, which is the process of compressing and releasing liquid in a suddenly closed small space. This improvement significantly reduces the sound decibels during pump operation.

2. * * High efficiency * *: The special design of the circular arc gear optimizes the liquid flow path, reduces internal leakage, and improves the pump's volumetric efficiency and energy conversion efficiency.

3. * * Long lifespan * *: The gentle contact of the gears reduces wear and heat generation, coupled with the precision of the design, which reduces the maintenance requirements of the pump and extends its service life.

4. Wide applicability: The low-noise circular arc gear pump is not only suitable for transporting low viscosity liquids such as clean water and light oil, but also for handling oils, chemicals, and other sensitive fluids with certain viscosity, and has a certain tolerance for small impurities in the medium.

5. * * Compact structure * *: Compared to other types of pumps, the circular arc gear pump has a smaller size, lighter weight, and is easy to install and maintain.

In short, the low-noise circular arc gear pump provides excellent noise reduction performance with its unique design, while also balancing efficiency and durability, making it an ideal choice for many applications that require quiet working environments, such as medical equipment, laboratory instruments, precision electronic manufacturing, and other industries.
