The function of the power component is to convert the mechanical energy

Hydraulic oil is the working medium that transmits energy in hydraulic systems, and it can be categorized into several major types, including various mineral oils, emulsions, and synthetic hydraulic oils. The function of a hydraulic system is to assist humans in performing work. It mainly consists of actuators that convert pressure into rotational or reciprocating motion.

Issues to Pay Attention to When Using Hydraulic Systems

For the adjustment of pressure control components, the system pressure control valve, specifically the relief valve, is generally adjusted first. Start from a pressure of zero and gradually increase the pressure until it reaches the specified pressure value. Then, sequentially adjust the pressure control valves of each circuit. The adjustment pressure of the safety relief valve of the main hydraulic pump should generally be greater than 10% to 25% of the working pressure required by the actuating components. The pressure valve of the fast-moving hydraulic pump is usually adjusted to be greater than the required pressure by 10% to 20%. If the unloading pressure is used to supply the control oil circuit and lubrication circuit, the pressure should be maintained within the range of 0.3 to 0.6 MPa. The adjustment pressure of the pressure relay should generally be lower than the oil supply pressure by 0.3 to 0.5 MPa.

How to prevent oil leakage in hydraulic systems

The selection of seals depends on the actual situation. Different working pressures, temperatures, media, types of motion, and speeds determine the different types of seals. For example, O-rings are suitable for sealing in static and rotating motions; Y-rings have good wear resistance and are suitable for sealing in reciprocating motions, etc. When receiving seals, it is important to carefully check the manufacturing date, deformation, aging, and whether the dimensions are qualified. If there are any issues, they should not be used forcefully.

The hydraulic press utilizes Pascal's law (which states that pressure in a confined fluid is transmitted uniformly) and the principle of leverage (the force applied on a lever is proportional to its distance from the pivot) to achieve powerful pressure output.

Analysis of the Current Development Status and Trends of the Hydraulic Press Industry in China

The hydraulic press utilizes Pascal's law (which states that pressure in a closed system is transmitted uniformly) and the principle of leverage (the force applied on a lever is proportional to its distance) to achieve powerful pressure output. It pumps liquid into the main cylinder through a hydraulic pump to generate pressure, which is then transmitted uniformly to a smaller slave cylinder. Since the piston area of the slave cylinder is larger than that of the main cylinder, the slave cylinder generates a greater force, thus completing various processing operations.
