Most of the power of the waste paper baler is provided by the hydraulic pump, so the standard for the hydraulic pump pressure is very strict, so here are some concepts related to the allowable pressure range of the waste paper baler hydraulic pump. In order to ensure the normal operation of the waste paper baler, it is necessary to adjust the pressure within the normal rated pressure.
1. The high allowable pressure of the waste paper baler under the condition of exceeding the rated pressure, according to the test standard, allows the hydraulic pump of the waste paper baler to operate briefly, which is called the high allowable pressure of the hydraulic pump.
2. One revolution of the hydraulic pump per revolution, the volume of the discharged liquid calculated from the change of the sealing volume of the waste paper baler is called the displacement of the hydraulic pump, and the hydraulic pump with adjustable displacement is called the variable pump. A hydraulic pump with a constant displacement is called a dosing pump.
3. Waste paper baler working pressure The output pressure of the hydraulic pump of the waste paper baler is actually called working pressure. The amount of working pressure depends on the size of the external load and the pressure loss on the drain line, regardless of the flow rate of the hydraulic pump.
4. Waste paper rated pressure The hydraulic pump of the waste paper baler is called the rated pressure of the hydraulic pump under normal working conditions, and the high pressure for continuous operation according to the test standard.
Due to the different uses of the hydraulic drive of the waste paper baler, the pressure required by the system is also different. If this value is exceeded, the pump will be overloaded, and the rated pressure will be restricted by the structural strength and leakage of the pump itself. In order to facilitate the design, production, and use of the hydraulic components of the waste paper baler, the pressure is divided into several grades.
