Coffee machine vibration pump and rotary pump, technical differences and working mechanism

There are technical differences and working mechanisms between the vibration pump and the rotary pump of the coffee machine. The vibration pump generates pressure through electromagnetic vibration to push water out. The structure is relatively simple and the cost is low, but the water flow control is not precise enough. The rotary pump generates pressure by driving the rotor inside the pump to rotate through the motor. The control is more precise and can adapt to different grinding degrees of coffee beans, but the structure is complex and the cost is higher. Both pumps have their own advantages and disadvantages. The choice depends on personal needs and budget.

In the world of coffee machines, vibration pumps and rotary pumps are two common types of pumps. They each have unique working principles and characteristics. This article will explore in detail the differences between the two pumps and the working principle of vibration pumps.

The basic difference between coffee machine vibration pump and rotary pump

1. Structural differences

There are obvious differences in structure between vibration pumps and rotary pumps. Vibration pumps mainly rely on the up and down vibration of the piston to generate pressure, push water through the coffee powder and extract the coffee, while rotary pumps use the high-speed rotation of the impeller to generate centrifugal force to press the water out and through the coffee powder.

2. Work efficiency

In terms of work efficiency, vibration pumps usually have higher extraction efficiency due to their structural characteristics. They can generate greater pressure in a short period of time and quickly complete the extraction of coffee. Due to the speed limit, the extraction efficiency of rotary pumps is relatively low, but the water flow is more uniform, which is suitable for making coffee that requires delicate water flow control.

3. Maintenance Cost

The maintenance of the vibration pump is relatively simple, and the main components are the piston and seals, which are easy to disassemble and clean. The impeller structure of the rotary pump is more complicated and relatively difficult to maintain, requiring professional maintenance tools. From the perspective of long-term use, the maintenance cost of the vibration pump may be lower.

4. Applicable scenarios

In home and commercial environments, vibration pumps are more popular with users due to their high efficiency and high pressure, while rotary pumps are more suitable for occasions that require precise control of coffee concentration, such as professional coffee shops, due to their stable extraction effect.

Detailed explanation of the working principle of vibration pump

1. Power drive

The vibration pump is driven by a motor, which drives the piston to vibrate up and down through a transmission device.

2. Vibration creates pressure

The up and down vibration of the piston creates pressure fluctuations, which allow the water to flow through the coffee grounds.

3. Sealing performance

The vibration pump is equipped with seals inside to ensure good sealing performance and prevent water leakage under high pressure environment.

4. Extraction and filtration

Water flows through the coffee powder under pressure to extract the coffee components, and then passes through the filtration system to remove the coffee grounds to obtain fragrant coffee.

After understanding the difference between vibration pumps and rotary pumps and the working principle of vibration pumps, we can better choose the coffee machine that suits us. For home users, vibration pumps may be more practical due to their high efficiency and easy maintenance. For professionals who pursue the ultimate coffee experience, the stable performance of rotary pumps may better meet their needs.

This article aims to provide readers with detailed information on the two pump types, helping everyone to gain a deeper understanding of the working principles of the coffee machine and provide more reference for their own coffee journey. I hope this article can provide some help and guidance for everyone on the road of coffee.
