After pressurizing a sealed container to the target value and shutting down the pump, a gradual pressure drop is observed within the container, leading to suspicions of an air leakage defect in the pump itself.

The current testing method is highly efficient, low-cost, and easy to automate. However, when applied to diaphragm water pumps operating with water as the medium, it harbors an overlooked logical flaw: passing an air leak test at 40 kPa does not guarantee the absence of water leakage at 90 kPa.

During product testing and feedback from field applications, we observed that Brushless DC diaphragm pumps exhibit significant abnormal noise under specific negative pressure conditions. Initially, this issue was often misdiagnosed as aerodynamic noise or assembly defects. However, a detailed analysis of the motor’s force dynamics revealed that the root cause lies in the destabilization of the "equilibrium point" between the pump’s compression load and the motor’s magnetic thrust at certain vacuum levels.

In medical testing equipment, the body fixation and inspection of microfluidic chips and biosensor chips, as well as their automated loading, unloading, and handling, all rely on a stable, clean, and compact micro vacuum source.

The alcohol fireplace uses a diaphragm pump to quantitatively transfer bioethanol from the storage tank to the combustion trough (some atomizing fireplaces also use it as a supply pump).

In dental scaler design, replacing traditional peristaltic pumps with diaphragm pumps is becoming a preferred option that balances quiet operation with performance.

Drawing on the experience of closed-loop control in brushless motor speed regulation, three different control strategies are proposed, tailored for medium-to-high speed, low speed, and ultra-low speed scenarios, respectively, to achieve stable ultra-low flow output in ultrasonic dental scalers.

Regarding the adhesion problem in diaphragm pumps caused by long-term inactivity, this article will first analyze the root cause of its mechanism, and then provide specific solutions and fundamental prevention strategies.
