Изобретение относитс  к центробежным насосам со спиральным отводом дл  перекачивани  жидкостей или газов.This invention relates to centrifugal pumps with a spiral outlet for pumping liquids or gases.

Известны центробежные насосы со спиральным отводом, имеющим подвижный  зык с устройством дл  его перемещени .Known centrifugal pumps with a spiral outlet, having a movable tongue with a device for moving it.

Цель изобретени  - автоматическое поддержание к. п. д. на различных режимах работы насоса.The purpose of the invention is to automatically maintain the efficiency in various operating modes of the pump.

Это достигаетс  тем, что устройство дл  перемещени   зыка выполаено в виде подпружненного поршн , помещенного в цилиндре , шток которого св зан с  зыком, а поршнева  полость сообщена с линией нагнетани  насоса.This is achieved in that the device for moving the tongue is made in the form of a spring-loaded piston placed in a cylinder, the rod of which is connected to the tongue, and the piston cavity is in communication with the pump discharge line.

На чертеже изображен предлагаемый насос.The drawing shows the proposed pump.

Он содержит спиральный отвод 1 насоса, в котором имеетс  щиток 2, один конец 3 которого прикреплен к корпусу спирального отвода , а второй 4 - образует  зык с горловиной 5.It contains a spiral outlet 1 of the pump, in which there is a shield 2, one end 3 of which is attached to the body of the spiral outlet, and the other 4 - forms a tongue with a neck 5.

В цилиндр 6 помещен поршень 7 с пружиной 8, а шток 9 поршн  7 через палец 10 соединен с концом 4 щитка.A piston 7 with a spring 8 is placed in the cylinder 6, and the piston rod 9 of the piston 7 is connected to the end 4 of the shield through a pin 10.

Порщнева  полость 11 через отверстие 12 сообщена с линией нагнетани  насоса, а подпоршнева  полость 13 через отверстие 14 - с атмосферой или со всасываюшей стороной насоса.The piston cavity 11 through the opening 12 is in communication with the pump discharge line, and the sub-piston cavity 13 through the opening 14 is connected with the atmosphere or with the suction side of the pump.

При увеличении давлени  нагнетани  поршень 7 сжимает пружину 8 и тем самым перемещает  зык и сужает горловину 5, и наоборот , при уменьшении давлени  горловина расшир етс .With an increase in the discharge pressure, the piston 7 compresses the spring 8 and thereby moves the tongue and narrows the throat 5, and vice versa, as the pressure decreases, the throat expands.

Предмет изобретени Subject invention

Центробежный насос, спиральный отвод которого имеет подвижный  зык с устройством дл  его перемещени , отличающийс  тем, что, с целью автоматического поддержани  к. п. д. на различных режимах работы насоса,A centrifugal pump, the spiral withdrawal of which has a movable tongue with a device for its movement, characterized in that, in order to automatically maintain the efficiency of the various operating modes of the pump,

устройство дл  перемещени   зыка выполнено в виде подпружиненного поршн , помещенного в цилиндре, щток которого св зан с  зыком , а поршнева  полость сообщена с линией нагнетани  насоса.The device for moving the tongue is made in the form of a spring-loaded piston placed in the cylinder, the brush of which is connected with the tongue, and the piston cavity is in communication with the pump discharge line.
