Problem with independent fan rotation in cryopumps
Thread Content
Hello, dear sea friends. There is currently a low-temperature liquid nitrogen pump of the variable-frequency type; the main motor is equipped with an independent cooling fan. The rotation direction of the main motor is definitely determined by the arrow on the pump body. So what should be the rotation direction of the independent fan? Is it also in line with the direction of rotation of the main motor?
Hello, poster! Based on the question posed by the original poster, it is first necessary to understand the function of the cooling fan: its role is to cool the main motor. To achieve this cooling effect, the air generated by the cooling fan must be directed toward the main motor; knowing this requirement helps determine the direction in which the cooling fan should rotate. In fact, no matter what you do, first clarify the purpose of doing it; based on that purpose, then determine the specific measures and steps to achieve it. In this way, everything you do will be organized and purposeful ； Knowing what to do, without being so passive and at a loss.
