(54) ВИБРАЦИОННЫЙ НАСОС ДВОЙНОГО ДЕЙСТВИЯ(54) DOUBLE ACTION VIBRATION PUMP

1one

Изобретение относитс к насосостроению, а имеййо к вибрационным насосам, и может быть применено в системах транспортировани жидкости общепромышленного назначени .The invention relates to pump engineering, and to vibration pumps, and can be applied in general purpose industrial fluid transportation systems.

Известен вибрационный насос двойного действи , содержащий корпус с входными клапанами и расположенный в нем порщейь с приводом 1 .A double acting vibrating pump is known, comprising a housing with inlet valves and a porsion with a drive 1 located therein.

Недостатком этого насоса вл етс сложна конструкци , больша энергоемкость .The disadvantage of this pump is its complex construction, which is very energy intensive.

Наиболее близким к изобретению по технической сущности вл етс вибрационный насос двойного действи , содержащий цилиндр с нагнетательными клапанами, расположенный в нем поршень со штоком, св занный с виброприводом, и устройство дл подвода жидкости в цилиндр 2.Closest to the invention, the technical essence is a double-acting vibration pump comprising a cylinder with pressure valves, a piston with a rod in it, connected to a vibro-drive, and a device for supplying fluid to the cylinder 2.

Недостатком известного насоса вл етс низкий КПД.A disadvantage of the known pump is low efficiency.

Цель изобретени - повцщение КПД.The purpose of the invention is to increase the efficiency.

Поставленна цель достигаетс тем, что в вибрационном насосе двойного действи , содержащем цилиндр с нагнетательными клапанами, расположенный в нем поршейь со штоком, св занный с виброприводом, иThe goal is achieved by the fact that in a vibration pump of double action, containing a cylinder with pressure valves, located in it is a piston with a rod, connected with a vibrodrive, and

устройство дл подвода жидкости в цилиндр, устройство дл подвода жидкости выполнено в виде трубки с радиальными капилл рными каналами, расположенной по оси цилиндра , а виброприБод - в виде неподвижной пьезокерамической пластины.a device for supplying liquid to the cylinder, a device for supplying liquid is made in the form of a tube with radial capillary channels located along the axis of the cylinder, and the vibroplate is in the form of a fixed piezoceramic plate.

На чертеже представлен насос, продольный разрез.The drawing shows the pump, a longitudinal section.

Вибрационный насос двойного действи содержит цилиндр 1 с нагнетательными клапанами 2 и 3, расположенный в нем порщень 4 со щтоком 5, св занный с виброприводом , и устройство дл подвода жидкости в цилиндр, которое выполнено в виде трубки 6 с радиальными капилл рными каналами 7, расположенной по оси цилиндра I, а 15 вибропривод - в виде неподвижной пьезокерамической пластины 8. Пластина 8 имеет две пары электродов (на чертеже не показаны) и башмаки 9.The double-action vibrating pump comprises a cylinder 1 with pressure valves 2 and 3, located therein a piston 4 with a brush 5, associated with a vibration drive, and a device for supplying fluid to the cylinder, which is made in the form of a tube 6 with radial capillary channels 7, located along the axis of cylinder I, and 15 the vibration drive - in the form of a fixed piezoceramic plate 8. Plate 8 has two pairs of electrodes (not shown) and shoes 9.

Вибрационный насос двойного действи 2Q работает следующим образом.Vibration pump double action 2Q works as follows.

Claims

When applying to one pair of electrodes of a piezoceramic plate 8 high-frequency resonant voltage, longitudinal and bending oscillations are excited in it, the frequency and phase characteristics of which are shifted relative to the corresponding characteristics of the other pair of electrodes. Attached to the piezoceramic plate 8 are shoes 9, which simultaneously perform elliptical movements, resulting in directional movement of the rod 5. Reversal of movement occurs when switching another pair of electrodes of the piezoceramic plate 8, resulting in a phase of bending oscillations changing relative to the phase of longitudinal oscillations by 180 °. When the piston 4 moves in one direction, pressure is created in the cavity on the side of the discharge valve 2, and a negative pressure is created on the other side of the valve 3, as a result of which the valve 3 is closed and the liquid through the capillary channels 7 of the tube 6 fills the cavity of cylinder 1. When the piston moves 4 in the opposite direction, the liquid is injected through the valve 3, and a vacuum is created in the cavity on the side of the valve 2, as a result of which the valve 2 is closed, and through the capillary channels 7 this part of the cavity is filled with liquid. The pump can be automated, you can adjust the mode. Pump can chhu Wu | U7L G7L G. / 1 V / IV. . .///J U / A KuTT / X U IW. f V I: I F | 1 Already I “F | IWI ": I I V. work in dosing mode and continuous; You can also adjust the flow and pressure of the liquid. The proposed implementation of the pump provides a significant increase in its efficiency. Claims of the invention A double-acting vibration pump comprising a cylinder with pressure valves, a piston with a rod connected therein associated with a vibro-drive, and a device for supplying fluid to the cylinder, characterized in that, in order to increase the efficiency, the device for supplying liquid is tubes with radial capillary channels located along the axis of the cylinder, and the vibration drive - in the form of a fixed piezoceramic plate.
