Description
ключаютс реверсивные золотники о, и часть потока из каждого контура поступает в магистрали подпитки через регулируемый дроссель И и теплообменник 10. Величина этой части потока из каждого контура задаетс настройкой дроссел 11. Дроссели 11 могут быть уетановлеиы в сливиой или в иапориой магистрали подпитки, при этом из различных контуров, в зависимости от необходимого теплообмепа , можно отводить различный поток рабочей жидкости. Суммарный поток рабочей жидкости через дроссели 11 определ етс производительиоетью насоса подиитки 6 и утечками в насосах 1 и гидромоторах 2. Давление в напорной магистрали подиитки задаетс настройкой предохранительного клапана 9.The reversible spools are connected, and part of the flow from each circuit enters the feed lines through an adjustable choke And and the heat exchanger 10. The value of this part of the flow from each circuit is set by setting the choke 11. The chokes 11 can be fed into the discharge or feed from the main feed, while from different circuits, depending on the required heat exchangers, you can divert a different flow of working fluid. The total flow of the working fluid through the throttles 11 is determined by the manufacturer of the feed pump pump 6 and the leaks in the pumps 1 and the motors 2. The pressure in the flow line of the feed box is set by setting the safety valve 9.
Таким образом осуществл етс необходимый отвод тепла из замкнутых контуров гидросистемы через теплообменнпк контура подпитки .Thus, the necessary heat removal from the closed circuits of the hydraulic system is carried out through the heat exchangers of the make-up circuit.
