Description

Pressure switch integrated with diaphragm pump

Technical Field

The utility model relates to the field of diaphragm pump accessories, in particular to a diaphragm pump integrated pressure switch.

The main working principle is that the pumping is generated by the driving of the diaphragm assembly to realize the fluid delivery. The miniature diaphragm pump has the characteristics of small volume, light weight, simple structure and convenient maintenance, can realize high-efficiency fluid delivery under low power, and is widely applied to fluid delivery and circulation systems in the fields of food, chemical industry, medicine, environmental protection, printing and the like.

The existing micro diaphragm pump is started or stopped, and is manually interfered, or the micro diaphragm pump is started or stopped through a manual control button or switch, so that the efficiency is obviously low and the operation is inconvenient due to frequent manual operation in the use process. There are also electronic controllers that control the operating state of the micro-diaphragm pump according to set parameters (for example, set start-up time period), and control the micro-diaphragm pump according to set parameters, which on the one hand requires a user's threshold for use, and on the other hand requires programming or operating a PLC, which is easy to overheat the diaphragm pump, and which, for a long time, easily damages the motor of the diaphragm pump, and which wastes energy. In addition, a sensor such as a flowmeter is attached to a water inlet/outlet pipe to control the micro diaphragm pump, which is relatively costly. Meanwhile, the difficulty in investigation is increased when the fluid conveying and circulating system fails, and maintenance is laborious.

Accordingly, further optimization and improvement are needed for existing diaphragm pumps.
