Известен гидроагрегат, содержащий бак, основной иасос ic оредвключенным струйным устройством и потребитель гидравлической эне)ргии - гидросистему, Причем |рабочее сопло струйного устройсива сообщено с напорной магистралью основного насоса.A hydraulic unit is known that contains a tank, a main pump and an integrated jet device and a consumer of hydraulic system — a hydraulic system; Moreover, the working nozzle of the jet device is in communication with the main line of the main pump.

Цель изобретени -снизить затраты энергии дл  создани  лодпора «а входе в на)0ос и повысить к.п.д. гидроагрегата.The purpose of the invention is to reduce energy costs for creating an underdraft at the entrance to and to increase the efficiency. hydraulic unit.

Дл  этого рабочее сопло струйного устройства сообщено со сливной магистралью, та« что через это сопло Протекает весь -расход, создаваемый ооновПым насосом, а на входе в «асос установлен обратный клапа .For this, the working nozzle of the jet device is communicated with the drain line, that “all the flow generated by the UNPY pump flows through this nozzle, and a return valve is installed at the entrance to the pump.

Схема гид|роагрвгата показана на чертеже.Scheme of hydro | roagrvgata shown in the drawing.

Гидроагрегат состоит .из бака 1, струйного устройства IB виде сопла 2 и диффузора 3, размещениых IB баке 1, камеры 4, основного насоса 5 с предохранительным -клапаном 6, гидросистемы-потребител  7, соедИНителыных трубопроводов 8, 9, 10 и обратного клапана 11.The hydraulic unit consists of the tank 1, the jet device IB in the form of a nozzle 2 and a diffuser 3, accommodated by IB tank 1, chamber 4, main pump 5 with safety valve 6, hydraulic system-consumer 7, connecting pipelines 8, 9, 10 and check valve 11 .

При работе гидроагрегата через сопло 2 протекает рас.ход жидкости, равный подаче насоса 5. При пуске гидроагрегата обратный клапан 11 уменьшает падение давлени  в камере 4, которое возни-кает за счет инерцпоннасти потока жидкос1И.When the hydraulic unit is in operation, a flow of fluid flows through the nozzle 2, equal to the pump 5 supply. When the hydraulic unit is started, the check valve 11 reduces the pressure drop in chamber 4, which occurs due to inertial flow of liquid.

Предмет изобретени Subject invention

Гидроагрегат, содержащий насос дл  питани  из бака гидросистемы-потребител  и предв«люченное струйное устройство, состо щее из рабочего и прием юго сопел с диффузором, отличающи йс  тем, что, с целью уменьшени  затрат энергии дл  создани  подпора на Входе в насос и повышени  к.п.д. гидроагрегата , рабочее сопло струйного устройства сообщено со сливной магистралью оотребител  дл  пропускани  через это сопло полногоA hydraulic unit containing a pump for feeding from a consumer hydraulic tank and a predetermined jet device, consisting of a working and receiving south nozzles with a diffuser, is characterized in that, in order to reduce energy costs to create backwater at the entrance to the pump and increase the ppm the hydraulic unit, the working nozzle of the jet device is communicated with the consumer’s main line to pass through the nozzle through

расхода насоса, а на входе в насос установлен обратный клапан.pump flow, and a check valve is installed at the pump inlet.
