Устройство блокировки гидравлической системы может быть использовано в системах насосных станций механизированных крепей. Предлагаемое изобретение обеспечивает повышение надежности устройства блокировки гидравлической системы. Гидравлическая система состоит из насоса электродвигателя и блоков потребителя. Устройство блокировки гидравлической системы включает блок контрольной аппаратуры, подключенной к золотниковому распределителю и порционеру. Шток порционера установлен напротив концевого выключателя с возможностью взаимодействия с ним. При наличии утечек происходит перемещение поршня порционера и его шток, взаимодействуя с концевым выключателем, отключает электродвигатель насоса. Особое подключение порционера в системе позволяет блокировать систему только при наличии в ней утечек.The blocking device of the hydraulic system can be used in the systems of pump stations of powered roof supports. The present invention provides improved reliability of the hydraulic locking device. The hydraulic system consists of a motor pump and consumer units. The blocking device of the hydraulic system includes a control equipment unit connected to the spool valve and the batch valve. Stockioner rod is installed opposite the limit switch with the ability to interact with it. In the presence of leaks, the piston of the portioner moves and its rod interacts with the limit switch and switches off the pump motor. Special connection of the portioner in the system allows blocking the system only if there are leaks in it.
