JP4488955B2 - Gas passage tank for electromagnetic vibration type pump - Google Patents

Description

  The present invention relates to a tank for an electromagnetic vibration type pump. More specifically, the electromagnetic vibration type is mainly used for air intake / exhaust to air mats for mobile or general indoors such as automobiles and ships, oxygen supply in fish tanks and domestic septic tanks, or sampling of inspection gas in pollution monitoring. The present invention relates to a gas passage tank for a pump.

  When a plurality of electromagnetic diaphragm pumps are connected, the discharge amount can be increased by connecting the plurality of pumps integrally, but the size increases accordingly. For example, when it is assumed that a plurality of pumps are integrated and used as an outdoor blower or the like, it is necessary to provide a housing for drip-proofing. In such a case, in particular, since the entire apparatus including the housing is enlarged and the installation place is limited, there is a demand for downsizing. In addition, there is a problem in that piping between a plurality of pumps becomes complicated.

  For this reason, in an electromagnetic diaphragm pump having a plurality of compression portions, the plurality of compression portions are covered with a single casing, and each compression portion includes a vibrator holding a permanent magnet and a peripheral portion fixed to the casing. A diaphragm having a central portion fixed to both ends of the vibrator, and a pair of diaphragms for supporting the vibrator so as to freely vibrate in an orthogonal direction of the diaphragm with respect to the casing; and the vibrator A field core in which magnetic poles are arranged with a predetermined amount biased in the vibration direction of the vibrator with respect to the permanent magnet, a coil wound around the field core, and the diaphragm as one wall surface, the vibrator Compression chambers arranged on both sides of the vibration direction, a valved suction port provided in the compression chamber, and a valved discharge port provided in the compression chamber for each compression unit In addition, among the field cores, the ones disposed between the vibrators of the adjacent compression units are integrally formed, and an alternating current is supplied to the coil to provide the magnetic poles of the field core. Some have power supply circuit means for exciting the diaphragm and vibrating the diaphragm by alternately attracting and repelling the permanent magnets to the magnetic poles (see, for example, Patent Document 1).
