Description

В известных конструкци х одноковшовых экскаваторов и других машин цикличного действи , в которых основные рабочие механизмы привод тс  в движение силовыми гидравлическими цилиндрами или другими гидродвигател ми и примен етс  насосно-аккумул торный привод, освобождаюша с , при тормозных режимах движени  рабочих органов, энерги  гаситс  в тормозных устройствах.In known constructions of single-bucket excavators and other cyclic machines, in which the main working mechanisms are driven by power hydraulic cylinders or other hydraulic motors, a pump-accumulator drive is used, released from the braking modes of movement of the working parts, energy is quenched braking devices.

Описываемый насосно-аккумул торный привод дает возможность рекуперировать энергию при тормозных режимах движени  рабочих органов благодар  наличию гидроаккумул торов и системы обратных клапанов, взаимодействующих между собой. Рекупераци  энергии осуществл етс  за счет возврата жидкости из полости повышенного давлени  гидроцилиндра в полость аккумул тора.The described pump-accumulator drive makes it possible to recover energy during the braking modes of movement of the working bodies due to the presence of accumulators and a system of check valves that interact with each other. Energy recovery is accomplished by returning fluid from the cavity of the cylinder pressure to the cavity of the accumulator.

На прилагаемом чертел е изображена принципиальна  схема описываемого привода.The attached drawing is a schematic diagram of the described drive.

Рабоча  жидкость под действием избыточного давлени  пор дка 5-8 кг1см поступает из наполнительного гидроаккумул тора 1,  вл ющегос  и баком, через фильтр 2 в насос 3, подающий ее под давлением через обратный клапан 4 в силовой гидроаккумул тор 5. Давление в силовом гидроаккумул торе (и тем самым заполнение его) автоматически поддерживаетс  в определенных пределах клапаном разгрузки 5 насоса 3, который переводит поток жидкости от насоса 5 или непосредственно в силовую магистраль, мину  обратный клапан 4, или в гидроаккумул тор 5.The working fluid under the action of overpressure, in the order of 5-8 kg1cm, flows from the filling accumulator 1, which is also the tank, through filter 2 to pump 3, which supplies it under pressure through a non-return valve 4 to the pressure accumulator 5. Pressure in the pressure hydroaccumulator (and thus filling it) is automatically maintained within certain limits by the discharge valve 5 of the pump 3, which transfers the fluid flow from the pump 5 either directly to the power line, to the backflow valve 4, or to the hydraulic accumulator 5.

Из гидроаккумул тора 5 рабоча  жидкость подаетс  через напорную магистраль к распределителю 7, который управл ет работой гидродвигйтел  8, сообща  или разобща  полости его с напорной или сливной магистрал ми.From the hydroaccumulator 5, the working fluid is supplied through the pressure line to the distributor 7, which controls the operation of the hydraulic motor 8, jointly or disconnecting its cavity with the pressure or drain lines.

Полости гидродвигател  с напорной и сливной магистрал ми соединены также и системой обратных клапанов 9 и 10. Два клапана 9 служат дл  пропуска в напорную магистраль (при наличии там давлени  выше, чем в гидроаккумул торе на величину гидравлических сопроThe cavities of the hydraulic engine with the pressure and drain lines are also connected by a system of check valves 9 and 10. Two valves 9 serve to pass into the pressure line (if there is pressure there is higher than in the hydraulic accumulator)
