1. Features:
- Miniaturized design: The water pump of the coffee machine is usually small in size to fit the overall size of the machine.
- Low power/low current: Generally works in the power range of tens of watts or less, and the current is also small.
- Low noise: With special design, the noise level is low and will not affect the use experience of the coffee machine.
- Fast start and stop: It can start and stop quickly to meet the instantaneous water supply needs of the coffee machine.
- Durable and reliable: It adopts high-quality materials and precision processing, with a long service life and high reliability.
2. Main applications:
- Hot water system water supply: Heat cold water to the required temperature and deliver it to key parts such as the brewing head.
- Steam system water supply: Provide water source for the steam generator to generate steam for milk frothing or other processes.
- Water pressure regulation: Ensure the best extraction effect of coffee by accurately controlling the water pressure.
3. Common water pump types:
- Centrifugal pump: Simple structure, low cost, widely used in mid- and low-end coffee machines.
- Diaphragm pump: contactless design, lower noise, used in mid-to-high-end models.
- Micro plunger pump: high precision, suitable for high-end coffee machines that require precise control of water pressure.
4. Performance requirements:
- Flow rate: meet the water supply needs of various working conditions of the coffee machine, usually 0.5-2 liters/minute.
- Water pressure: depending on the type of coffee machine, the water pressure is generally 1-20 bar.
- Durability: can operate reliably for a long time in harsh environments such as humidity, high temperature, and scale.
In general, as a key component, the performance of the coffee machine water pump directly affects the user experience and reliability of the coffee machine. Excellent water pump design is an important basis for achieving high-quality coffee. If you have other questions, please feel free to discuss with me.
