What is the advantage of hydraulic automatic transmission of grinding machine table?
Its advantage is compared with the mechanical drive system:1. small vibration.2. stepless speed change can be achieved.3., smooth movement, low noise.Working principle: the composition and working principle of the hydraulic transmission system of the simple grinding machine. The motor drives the hydraulic pump to absorb oil from the tank, and the hydraulic pump converts the mechanical energy of the motor to the pressure energy of the liquid. Hydraulic medium through the pipeline through the throttle valve and reversing valve into the hydraulic cylinder left chamber, to promote the piston to move the table to the right, the hydraulic cylinder to the right cavity of the hydraulic medium discharged by reversing valve flow back to the tank. After reversing the valve, the hydraulic medium enters the right chamber of the hydraulic cylinder, so that the piston moves left and pushes the worktable to move backwards. Changing the opening of the throttle valve can adjust the speed of the hydraulic cylinder. The pressure of the hydraulic system can be adjusted by overflow valve. In drawing the hydraulic system diagram, for the sake of simplification, the prescribed symbols are used to represent the hydraulic components, which are called functional symbols.
You should consider this horizontal hydraulic transmission and power transmission, vertical movement speed is adjustable, this premise is that you must use stepper or servo motor or pneumatic drive mode, compared with the hydraulic transmission, pneumatic transmission stability is relatively poor, and the motor drive mode and the maintenance cost the mechanical structure of production costs are relatively much higher, so the workbench of the grinding machine using hydraulic drive is the best choice in the economy and the mechanical design.
The advantage is that compared with the mechanical transmission system, there are two points in brief, 1) the vibration is small; 2) stepless speed change can be realized. Hope to help you, not Suoxie.
