Coffee machine pump motor is an important part of the espresso machine, its working principle is relatively simple, but it is very critical. The pump motor is the heart of the coffee machine, and its main task is to provide stable water pressure, ensuring that the coffee machine can provide hot water according to the preset pressure and flow rate, so as to make a cup of high-quality coffee. The heart is composed of a pump head + AC induction motor.

  First of all, let's understand the basic structure of the pump motor. The pump motor is mainly composed of AC induction motor, pump body, impeller and pump cover. The pump body is a cylindrical structure that houses the impeller and other internal parts. The impeller is made of metal or plastic, similar in shape to the propeller of an aircraft, and the number of blades is generally three to five. The pump cover plays the role of fixing and sealing to ensure the normal operation of the pump.

  Next, let's look at the working principle of the pump motor. When the pump motor is energized, the motor begins to rotate, driving the impeller to rotate. The rotation of the impeller creates centrifugal force, which causes the water inside the pump to be thrown to the outside of the impeller, forming a low pressure area. At the same time, a high-pressure zone is formed in the center of the impeller, generating an outward thrust. In this way, part of the water in the high-pressure area is discharged from the pump body to form a water column. In the application of the Italian coffee machine, the water column produced by the pump is transported to the heater through the water pipe. The heater heats the water to a preset temperature and then feeds it through another pipe to the brewing head of the coffee maker. Here, the hot water brews the coffee powder, and the coffee oil and dissolved substances in the coffee powder are extracted to form a cup of fragrant coffee.

   It is worth noting that the performance of the pump motor directly affects the performance of the coffee machine. The flow and pressure of the pump must be precisely controlled to ensure that the taste and concentration of the coffee meet the requirements. In addition, in order to ensure the normal operation and service life of the pump, regular maintenance and maintenance is also essential.

  In summary, the working principle of the coffee machine pump motor is to drive the impeller to rotate through the motor, generating centrifugal force to form a low pressure area and a high pressure area, so as to achieve water transportation and heating. Makes us a delicious coffee.
