Description

Известные шестеренчатые насосы с наружным заценлением и подводом жидкости через два всасывающих канала, разделенных перемычкой , не обеспечивают надежной герметизации каждой всасывающей магистрали и в случае попадани  в одну из магистралей воздуха насос практически выходит из стро .Known gear pumps with external locking and supplying fluid through two suction channels separated by a jumper do not provide reliable sealing of each suction line and if they get into one of the air lines the pump almost goes out of order.

Описываемый шестеренчатый одно;:екционный насос не имеет-указанного недостатка; он обеспечивает одновременную откачку двух различных жидкостей и нагнетание их смесиОсобенность насоса состоит в том, что кажда  сторона перемычки, прилегаюш;а  к шестерн м насоса, имеет длину большую, чем шаг зуба шестерни.Described gear one;: a lection pump has no-specified drawback; it ensures that two different liquids are pumped out simultaneously and inject them into a mixture. The specific feature of the pump is that each side of the bridge is adjacent, and to the gear of the pump it is longer than the pitch of the gear wheel.

Насос используетс  преимуш,ественно дл  масл ных систем быстроходных дизелей.The pump is used mainly for oil systems of high-speed diesel engines.

На чертеже изображена схема шестеренчатого односекционного насоса.The drawing shows a diagram of a gear single pump.

Перемычка / раздел ет всасывающие каналы 2 и 3. Стороны перемычки /, прилегающие к шестерн м 4 и 5 насоса, по длине больше шага зуба шестерен. Отстойники нижнего картера дизел  соединены трубопроводами с всасываюшими отверсти ми 5 и 7. Шестерни - и 5, враша сь в противоположные стороны, засасывают масло из отстойника нижнего картера через всасываюшие отверсти  5, 7 и каналы 2, 5 и гон т его через полости S, 5 и /О и выходное отверстие // в бак дл  масла.Jumper / separates the suction channels 2 and 3. The sides of the jumper / adjacent to the gear 4 and 5 of the pump are longer than the tooth pitch of the gears. The sumps of the lower crankcase of the diesel engine are connected by pipelines with suction inlets 5 and 7. Gears - and 5, turned in opposite directions, suck up oil from the sump of the lower sump through suction inlets 5, 7 and channels 2, 5 and drive it through cavities S, 5 and / O and the outlet // to the oil tank.

При работе дизел  в наклонном положении в одном из отстойников нижнего картера находгтс  воздух. При вращении шестерен 4 н 5 в направлении стрелок, указанных, на чертеже, и при размере сторон перемычки У, большем шага зуба шестерен, попадание воздуха из полости 8 в полость 9 и, наоборот, из полости 9 в полость 8 исключено.When the diesel engine is operating in an oblique position, air is found in one of the sumps of the lower crankcase. When the gears 4 n 5 are rotated in the direction of the arrows indicated in the drawing, and when the size of the jumper sides U is larger than the tooth pitch of the gears, air from the cavity 8 into the cavity 9 and, conversely, from cavity 9 into the cavity 8 is excluded.

Смешивание масла с воздухом .может происходить только в полости 10, что не отражаетс  на работе. В полости 10, вследствие большогоMixing oil with air can occur only in cavity 10, which is not reflected in work. In cavity 10, due to the large

Предмет изобретени Subject invention

Шестеренчатый односекционный насос с наружным зацеплением и подводом жидкости через два всасываюш.их канала, разделенных перемычкой , отличающийс  тем, что, с целью обеспечени  одновременной откачки двух различных жидкостей и нагнетани  их смеси, кажда  сторона перемычки, прилегающа  к-шестерн м насоса, выполнена с длиной, большей шага зуба шестерни.A single-section gear pump with external gearing and fluid supply through two suction ducts separated by a jumper, characterized in that, in order to ensure simultaneous pumping out of two different liquids and injecting a mixture of them, each side of the jumper adjacent to the gear pump has a length greater than the pitch of the gear tooth.
