The three main components of a hydraulic press

Thread Content

Flow control valves include: throttle valves, one-way throttle valves, speed control valves, one-way speed control valves, stroke throttle valves, as well as one-way stroke throttle valves and one-way stroke speed control valves. III. Actuators The actuators include hydraulic cylinders and hydraulic motors. 1. Hydraulic cylinders include various types such as those used in vehicles, single-acting cylinders, hydraulic oil cylinders, swing cylinders, single-acting multi-stage cylinders (sleeve cylinders), double-acting multi-stage cylinders, and spring-return cylinders. 2. Hydraulic motors: Hydraulic motors include gear motors, vane motors, piston motors, etc.; in other words, almost any constant-displacement oil pump can theoretically function as a motor. 3. Low-speed high-torque hydraulic motor (1) Internal meshing cycloidal motor ； (2) Internal curve hydraulic motors, available in shaft-rotating and housing-rotating types ； (3) Dual-disc axial piston motor ； (4) Radial piston hydraulic motor ； (5) Ball-plug type low-speed high-torque hydraulic motor ； (6) Static-balanced low-speed, high-torque, low-hydraulic-pressure motor.
