四柱液压机单油缸和双油缸的区别？
four-column hydraulic pressAccording to the work requirements can be designed into a single cylinder, double cylinder, three cylinder, multi cylinder and other structures. So, what is the difference between a single cylinder and a double cylinder four-column hydraulic press?
single cylinder four column hydraulic press
Two-cylinder four-column hydraulic press
In short, the double-acting cylinder of the four-column hydraulic press has ports A and B. This means that oil enters the cylinder through port a, pushing the piston down. When the controller requests the piston to retract, oil is delivered to port B and the piston is pushed up. The double-acting cylinder uses hydraulic power to expand and contract. You can judge whether the cylinder has a dual function by observing the number of ports. In contrast, the single-acting cylinder of a hydraulic machine has a port that moves the piston downward by the pressure of the pump, but is retracted by an internal spring. The double-acting cylinder has a pressing and pulling power, which is usually controlled by the joystick controller. Single-acting cylinders have pressure only.
From a professional point of view, there is a clear difference between the single cylinder and the double cylinder of the four-column hydraulic press. The single cylinder is generally used in the small tonnage hydraulic press, and the multi-cylinder is generally used in the large tonnage hydraulic press. Moreover, this will also affect the product price of the four-column hydraulic press, so consumers must pay attention to the machine design when ordering the four-column hydraulic press.
