Working Principle
Internal eccentric gear pumps are positive displacement and consist of two moving parts. While the peripheral gear connected to the pump shaft rotates, it also transmits motion to the idler gear and the idler gear also rotates. During this rotation, the idler gear and the peripheral gear are separated from each other by the crescent and a vacuum is created. Thanks to the vacuum created, the pump absorbs a certain amount of liquid. The liquid drawn into the pump moves towards the discharge port in the tooth cavities. In the discharge mouth, the idler gear and the peripheral gear engage each other, creating pressure and allowing the liquid to be ejected. Pump; In each revolution of the pump shaft, it transfers the liquid as much as its volume. Therefore, the capacity of the pump is directly proportional to its size and revolution. The working principle of internal eccentric gear pumps is shown schematically below.
Internal eccentric gear pumps are collected in two main groups, with and without console. The console provides the opportunity to convert the inlet and outlet ports of the pumps into eight different positions for ease of assembly (with 45º intervals), and it also allows the pumps to work for a long time under more severe conditions due to the more rigid bearing of the pump shaft.
