STAND FOR RESOURCE TEST DRIVE lip seal HYDROCYLINDERS hydromanipulator forest machines

摘要

Stand for fatigue tests lip seals drive cylinders hydromanipulator forest machine comprising a hydraulic cylinder with a lip seal related to the field of mechanical engineering provides an effective testing and reducing complexity. Mounted on the frame, characterized in that it is provided with an adjustable throttle valve type, providing a biasing force simulating resistance to movement of the working bodies in cranes, hydraulic pump and a two-position distributor with an automatic return position. This utility model can be used for testing of gaskets hydraulic cylinders and other machines, as well as in the development of process equipment, which is necessary to provide reciprocating action mechanism without additional control of switching action.
