Description

В известных способах испытани  объемных насосов гидравлическа  энерги , вырабатываема  испытываемым насосом, обычно не используетс . С целью уменьшени  расхода энергии предлагаетс  нагнетаемую насосом жидкость использовать дл  привода гидродвигател , вращающего испытуемый насос. Преодоление зредных сопротивлений предусматриваетс  за счет работы дополнительного насоса с механическим приводом.In the known methods of testing volumetric pumps, the hydraulic energy produced by the pump under test is usually not used. In order to reduce energy consumption, it is suggested that the pumped fluid be used to drive the hydraulic motor, which rotates the pump under test. Overcoming the resistances is provided by the operation of an additional pump with a mechanical drive.

На чертеже приведена схема предлагаемого способа испытани  объемных насосов.The drawing shows a diagram of the proposed method for testing volumetric pumps.

Насос / приводитс  во вращение гидравлическим двигателем 2, непосредственно или через редуктор 3. Мощность и приведенный к залу насоса удельный расход жидкости гидродвигателем должны быть несколько выще, чем мощность и удельна  производительность насоса на величины, соответствующие потер м энергии в системе. Потери энергии компенсируютс  вспомогательным насосом 4 с механическим приводом. Скорость гидродвигател  регулируетс  дросселем с регул тором 5 или другим регулирующим устройством. Давление в системе регулируетс  пружинным предохранительным клапаном 6. Рабоча  жидкость циркулирует через промежуточную емкость - бак 7.The pump / is driven by a hydraulic motor 2, either directly or through a gearbox 3. The power and the specific flow rate of the hydraulic motor brought to the pump room must be somewhat higher than the power and specific pump capacity by values corresponding to the energy loss in the system. The energy losses are compensated by the mechanically driven auxiliary pump 4. The speed of the hydraulic motor is controlled by a throttle with a regulator 5 or other control device. The pressure in the system is regulated by a spring-loaded safety valve 6. The working fluid circulates through an intermediate tank — tank 7.

Предмет изобретени Subject invention

Способ испытани  объемных насосов, отличающийс  тем, что, с целью уменьщени  расхода энергии, нагнетаемую насосом жидкость используют дл  привода гидродвигател , вращающего насос, и компенсируют расход мощности на преодоление вредных сопротивлений путем подачи жидкости к гидродвигателю дополнительным насосом с механическим приводом.The method of testing volumetric pumps, characterized in that, in order to reduce the energy consumption, the pumped liquid is used to drive the hydraulic motor, which rotates the pump, and compensates the power consumption for overcoming harmful resistance by supplying the fluid to the hydraulic engine with an additional pump with a mechanical drive.
