Miniature diaphragm pump works
Miniature diaphragm pump refers to the miniature vacuum pump, which means that with one into the exhaust nozzle, the exhaust nozzle of each one by the internal mechanical device so that the pump reciprocating reciprocating diaphragm, and at the entrance to continue to form a vacuum or negative Pressure, exhaust nozzle at a slight positive pressure; working medium is mainly gas, a compact instrument. Miniature diaphragm pump works: The first mode of work: the motor circular motion through the mechanical device so that the internal diaphragm reciprocating pump to compress, stretch the pump cavity of the air to form a negative pressure at the suction port and Atmospheric pressure generated outside the pressure difference, the role of the pressure difference, the gas inhalation pump chamber, and then discharged from the exhaust port. The second mode of operation: micro-diaphragm pump is the use of screw rotation to suction and discharge liquid. The miniature diaphragm pump is an active screw which is driven by a prime mover. The screw on both sides is a driven screw, which rotates reversely with the active screw. The main, driven screw thread are double-headed thread. Due to the mutual engagement of the screws and the close cooperation of the screw with the inner wall of the liner, one or more sealed spaces are separated between the suction and discharge of the miniature diaphragm pump. As the screw is rotated and engaged, these sealed spaces are constantly formed at the suction side of the pump, the liquid in the suction chamber is enclosed therein and continuously displaced in the axial direction of the screw from the suction chamber to the discharge end, to be enclosed in the spaces Continued discharge of liquid, like a nut in the screw rotation is continuously pushed forward, as the case, which is the basic principle of micro-diaphragm pump.
