Micro-Vacuum Pump is different from Oil-less Vacuum Pump, Pitch Screw Vacuum Pump.
The essence of the vacuum pump suction: The use of the power of the micro-vacuum pump, the suction inlet generated by the negative pressure and the pressure difference between the outside atmosphere, through a type of contact elements of the suction cup firmly absorb the object, so as to play the role of hanging, fixing, moving objects.
When it is necessary to release the inhaled object, the pump must first be turned off, and it cannot be discharged. After the pump is turned off, because the pump has a certain filling capacity, and the vacuum will continue for a period of time (the length of time depends on the leakage situation of the system), the object will not necessarily fall off immediately.
A friend said, I know there is a micro air pump, you can pump secondary air, the model is PCF5015N, why not this cycle of pumping, the object adsorption, and then the next cycle, the outside air to the suction cup, not can quickly release the object?
Some friends believe that the miniature vacuum pump (that is, the single suction miniature negative pressure pump) in this cycle process, the suction is large, the object adsorption; In the next cycle, the motor is reversed and inflated, and the outside air is filled into the suction cup, and the object can not be quickly released?
Friends with the above two ideas will understand. Because in their view, the pump exhaust port, the exhaust port is interchangeable, so the realization of their idea is feasible;
However, the actual situation is that the current micro air pumps, micro vacuum pumps, etc., including domestic micro air pumps, micro vacuum pumps and most of the foreign micro air pumps, micro vacuum pumps, etc., due to internal processes and other reasons, only allow the gas to flow one-way from the intake port to the exhaust port, and vice versa. It is not a simple reverse motor that can change the direction of the air flow to meet the above requirements for releasing objects.
