The coffee machine water pump motor is the core component of the coffee machine. There are two types of water pump motors commonly used in general coffee machine water pump motors: vibration pumps and vane pumps (also called rotary pumps). Vibration pumps are often used in home coffee machines, while rotary pump motors are often used in office coffee machines and commercial coffee machines. Let's explain in detail the characteristics of the coffee machine rotary pump (vane pump) motor:
1. Coffee machine rotary pump mechanism
As the name suggests, the coffee machine rotary pump is a pump that transports liquids through rotational motion. In the coffee machine, it is mainly responsible for extracting water from the water tank and delivering it to the coffee powder at a stable pressure to extract the essence of coffee. The coffee machine rotary pump is a common pressure regulating device that can help the coffee machine control the pressure. The mechanism of the pump mainly includes a pulley and a hydraulic device. When the pulley starts to rotate, the hydraulic system begins to adjust the pressure of the pump to reach the required control pressure.
2. The principle of pressure regulation of the coffee machine rotary pump
The coffee machine rotary pump usually consists of an axis, a rotor, a stator and a seal. When the motor drives the rotor to rotate, the volume of the cavity between the rotor and the stator changes periodically, thus generating vacuum and pressure. The pressure regulation principle of the coffee machine rotary pump is to adjust the pressure by rotating the pump. Specifically, when the coffee machine is started, the rotary pump starts working. The rotation of the pulley of the rotary pump will move the small rod that adjusts the pressure, thereby affecting the pressure. When the small rod moves to meet the required pressure, the pressure of the coffee machine reaches the set value. There are fan-shaped blades inside the rotary pump. The rotation of the motor is used to gradually and rapidly increase the pressure, which can increase the low-pressure water to 8-10bar of the extraction coffee pressure. Even if the inflowing water is under no pressure, it can maintain a stable extraction pressure by self-priming and pressurizing. This pressure difference forces the liquid to enter the pump chamber from the water inlet and be transported to the water outlet. The pump of the coffee machine needs to maintain a fixed pressure to ensure that the coffee soaking time, cooking degree and taste can reach the best state.
3. Advantages of coffee machine rotary pump
The coffee machine rotary pump has many advantages.
1. Stable pressure: This pressure regulating device can automatically adjust the pressure of the pump to ensure that the coffee machine can maintain a stable pressure output under any condition.
2. Low noise: Since the pressure control of the rotary pump is more precise, the coffee made by the coffee machine tastes better. The rotary pump is larger in size, more expensive but less noisy.
3. Long life: The rotary pump has a relatively simple structure and high durability. The motor and pump head are separated for simple maintenance and operation. The extraction pressure can be adjusted manually. It is strong and durable and can maintain stable pressure even without water pressure.
Overall, the coffee machine rotary pump (water pump motor) is a stable, reliable and easy-to-operate pressure regulating device. It plays a very important role in the process of making coffee machines. It is one of the important devices worth knowing for coffee lovers. It is mainly suitable for commercial semi-automatic coffee machines or large commercial fully automatic coffee machines. .
Honlite has two main customized solutions for office/commercial coffee machine water pump motors: 1. C9455 AC induction motor; 2. BLDC60 DC brushless motor. The C9455 AC induction motor uses capacitor starting and has the characteristics of high power 300W, high torque, low noise, low cost, medium and long life, etc. In addition to the same advantages as the C9455 AC induction motor, the BLDC60 DC brushless motor also has the characteristics of low heat generation, long working time, ultra-long life (reaching more than 20,000 hours), stable operation (Honlite can match stable drivers), etc. It can fully meet the application of office coffee machines and large commercial fully automatic coffee machines.
