Abstract
The application discloses a kind of suction stable vacuum pumps.There are side covers on the two sides of the shell, and the side covers are provided with vacuum ports on the side faces.The motor is arranged on the shell, and the output shaft of the motor extends into the shell.The output shaft of the motor is arranged in the crank connecting rod mechanism, and the rotary motion of the motor is converted into linear motion by the crank connecting rod mechanism.The main diaphragm is arranged in the side covers on the two sides of the crank connecting rod mechanism, and the main diaphragm is connected with the crank connecting rod mechanism.The negative pressure gas circuit is arranged in the side covers, and the inner end structure of the negative pressure gas circuit cooperates with the main diaphragm structure.The outer end of the negative pressure gas circuit is connected with the corresponding vacuum port, and the negative pressure gas circuit and the main diaphragm are respectively provided with check diaphragms.The main diaphragm is of an elliptical structure, the long semi-axis of the main diaphragm is a, and the short semi-axis is b.The application avoids the sharp fluctuation of vacuum degree and flow rate, ensures the stability of adsorption or transportation, and cools the motor by exhaust.
