Working principle of dc mini vacuum pump
The core technology of the micro electric vacuum pump lies in its diaphragm movement. When the motor drives the diaphragm to reciprocate, the suction chamber and exhaust chamber of the pump are alternately formed, thereby completing the suction and exhaust process. During the inhalation process, due to the downward pressure of the diaphragm, a negative pressure is formed in the inhalation chamber and the gas is inhaled. During the exhaust process, the rise of the diaphragm pushes the gas into the exhaust port. This reciprocating motion forms a continuous air flow, completing the work of the vacuum pump.
Dimension Drawing
Suction performance of dc electric vacuum pump
The suction performance of the small vacuum pump is mainly reflected in its suction rate, vacuum degree and reliability. Among them, the suction rate determines the amount of gas that the pump can inhale per unit time; the vacuum degree reflects the lowest pressure that the pump can reach within a certain period of time. Reliability involves the life, durability and stability of the pump.
Suction technical requirements of mini electric vacuum pump
The suction technical requirements for micro diaphragm vacuum pumps mainly include the following aspects: first, the pump is required to achieve a certain suction rate and vacuum degree to meet application needs; secondly, the pump is required to operate stably, with low noise and long life; Finally, the pump is required to be compact in structure and easy to install and maintain.
Factors affecting the suction performance of micro diaphragm vacuum pumps and their solutions
There are many factors that affect the suction performance of micro diaphragm vacuum pumps, including the structural design of the pump, material selection, manufacturing process, motor performance and usage environment. In order to improve the suction performance of the dc membrane vacuum pump, it can be optimized from the following aspects:
1. Optimize the structural design of the portable pump: By improving the structural design of the pump, its suction efficiency and energy consumption can be reduced. This includes measures such as improving the air inlet design, increasing airflow channels, and optimizing the shape of the diaphragm.
2. Choose suitable materials: Choose suitable materials according to application requirements to improve the durability and stability of the pump. For example, choose high-strength, corrosion-resistant materials to increase pump life and reliability.
3. Improve the level of manufacturing technology: By improving the level of manufacturing technology, the accuracy and coordination of each component of the pump can be ensured, thereby improving its operating efficiency and stability.
4. Improve motor performance: select high-efficiency, low-noise motors and optimize motor control algorithms to reduce energy consumption and improve pump operation stability.
5. Adaptable use and maintenance: Reasonably adjust the operating parameters and maintenance measures of the pump according to the actual use environment and conditions to ensure its long-term stable operation and extend its life.
