Mini vacuum pump play an increasingly important role in today's industrial production and laboratories. Their efficient suction performance and compact structure make them the preferred vacuum pump type in many fields. This article will deeply explore the suction technology of micro diaphragm vacuum pumps, analyzing its working principle, performance, technical requirements, and factors affecting performance.

Technical Specification

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.

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.
