Abstract
The utility model relates to a seven-cavity typed micro diaphragm pump, comprising a fluid chamber, a diaphragm chamber, a diaphragm, a fluid chamber support and an eccentric wheel support. The fluid chamber and the fluid chamber support are connected with each other by a bolt and a motor. The inside of the fluid chamber is provided with a diaphragm chamber. The diaphragm chamber is provided with a water outlet cavity. The upside of the diaphragm chamber is provided with a drain check valve, a spring leaf and a pressure plate in turn. Seven compression cavities are uniformly arranged on the edge of the diaphragm chamber. Absorption check valves are installed inside the compression cavities. Corresponding pistons are arranged on the bottom of the absorption check valve. The bottom of the diaphragm is fixed on the diaphragm. The diaphragm is arranged on the upside of the fluid chamber support. The diaphragm and the eccentric wheel support on the lower part of the fluid chamber support pass through seven holes on the fluid chamber support and are connected with each other. The seven-cavity typed micro sized diaphragm pump has the beneficial effects that the structure of the compression cavity of the diaphragm pump is designed reasonably, the working efficiency of the motor is improved, energy sources are saved, and the low rotating speed, low noise and high efficiency of the motor are realized under the condition of the same flow quantity.
Description
Technical field
The utility model relates to a kind of diaphragm pump, relates in particular to a kind of seven cavate miniature diaphragm pumps.
Background technique
At present, what miniature diaphragm pump commonly used adopted is three chambeies (three compression chambers) structures, because this miniature diaphragm pump structure has very big narrow limitation, makes its working efficiency relatively the end of than, wastes energy; And, when the needs augmented flow, only can realize by improving motor speed or increasing the eccentric wheel angle; Yet these two kinds of methods all can increase making diaphragm pump vibration aggravation and noise.
The model utility content
The purpose of this utility model provides a kind of seven cavate miniature diaphragm pumps, to overcome the deficiency low in big flow work limitation rate, that noise is high, vibration is big.
The purpose of this utility model is achieved through the following technical solutions:
A kind of seven cavate miniature diaphragm pumps, comprise fluid chamber, chamber of septum, diaphragm, fluid chamber's support and eccentric wheel support, described fluid chamber bottom is provided with fluid chamber's support, fluid chamber is connected with motor by screw with the fluid chamber support, fluid chamber inside is provided with chamber of septum, described chamber of septum is provided with water chamber, the water chamber upper end is coated with the discharge safety check, discharge on the safety check and be pressed with spring sheet, the pressing plate of described spring sheet upside is pushed down spring sheet and discharge safety check, and is locked on the chamber of septum by screw; The chamber of septum edge is evenly distributed seven compression chambers, and compression chamber communicates with the water chamber of chamber of septum respectively, and inhalation check valve is housed in the compression chamber, and described inhalation check valve bottom is provided with corresponding piston; The chamber of septum bottom is diaphragm fixedly, described diaphragm is at fluid chamber's support upside, fluid chamber's support downside is provided with the eccentric wheel support, diaphragm is connected with seven holes that the eccentric wheel support passes fluid chamber's support, and the piston in the described compression chamber is pressed on the diaphragm and is locked on the eccentric wheel support by screw.
The beneficial effect of seven cavate miniature diaphragm pumps described in the utility model is: the compression chamber reasonable in design of diaphragm pump, improve the working efficiency of motor, and save the energy, realized that under same traffic it is low to have a motor speed, the advantage that noise is little, efficient is high.
