Is the power of waste paper packer provided by hydraulic pump or by the machine itself?
Feb 20,2021
Most of the power of waste paper packer is provided by hydraulic pump, so the standard of hydraulic pump pressure is very strict. Therefore, several concepts about allowable pressure range of hydraulic pump of waste paper packer are listed below. In order to ensure the normal operation of waste paper packer, it is necessary to adjust the pressure within the allowable range of normal rated pressure.
1. Under the condition that the maximum allowable pressure of waste paper packer exceeds the rated pressure, according to the test standard, the maximum pressure value that allows the hydraulic pump of waste paper packer to run temporarily is called the maximum allowable pressure of hydraulic pump.
The volume of the discharged liquid calculated by the change of the geometric dimension of the sealing volume of the waste paper packer is called the displacement of the hydraulic pump, and the hydraulic pump with adjustable displacement is called the variable displacement pump; A constant displacement hydraulic pump is called a constant displacement pump.
2. Working pressure of waste paper packer the output pressure of hydraulic pump of waste paper packer is called working pressure.
The size of the working pressure depends on the size of the external load and the pressure loss on the oil discharge pipeline, but has nothing to do with the flow of the hydraulic pump.
3. Rated pressure of waste paper under normal working conditions, the highest pressure of the hydraulic pump of waste paper packer in continuous operation according to the test standard is called the rated pressure of the hydraulic pump.
Due to the different uses of the hydraulic transmission of waste paper packer, the pressure required by the system is also different. Exceeding this value will overload the pump, and the rated pressure is restricted by the structural strength and leakage of the pump itself. In order to facilitate the design, production and use of hydraulic components of waste paper packer, the pressure is divided into several grades.
