The Three Pressures Of Hydraulic Press Machine

First of all, we need to know that the three common pressures of hydraulic press machines are: working pressure, rated pressure, and high allowable pressure. So what is the difference between these three pressure oils and what do they mean?
When the hydraulic press machine exceeds the rated pressure, according to the experimental standards, the hydraulic pump is allowed to run for a short time. The high pressure value is called the high allowable pressure of the hydraulic pump. If the pressure is exceeded, the leakage of the pump will increase rapidly.
Working Pressure
The output pressure of the hydraulic pump of the hydraulic press machine when it is actually working becomes the working pressure. The working pressure depends on the size of the external load and the pressure loss on the oil discharge line, and has nothing to do with the flow of the hydraulic pump.Rated Pressure
Under normal working conditions, the high pressure of the hydraulic pump of hydraulic press machine in continuous operation according to the experimental standards is called the rated pressure of the hydraulic pump.
When the hydraulic press machine exceeds the rated pressure, according to the experimental standards, the hydraulic pump is allowed to run for a short time. The high pressure value is called the high allowable pressure of the hydraulic pump. If the pressure is exceeded, the leakage of the pump will increase rapidly.
