Waste paper baler vane pump, the vane pump converts the mechanical energy of power machinery into hydraulic machinery (potential energy, kinetic energy, pressure energy) through the rotation of the impeller and the influence of the blade on the centripetal force. The pressure oil when the rotor of the vane pump rotates. Next, the tip is placed on the inner surface of the stator. The working space formed by the two blades and the inner surfaces of the rotor and the stator first discharges oil from small to large, and then from large to small. When the blade rotates once, oil suction and oil discharge ends twice. The vane pump has a simple structure and flow rate. On average, the displacement is large, the efficiency is high, and the importance of small parts exceeds one ton per hour.
The allowable pressure of the waste paper baler exceeds the rated pressure. The high pressure value that makes the hydraulic pump of the waste paper baler run briefly is called the high pressure allowable pressure of the hydraulic pump. For each revolution of the hydraulic pump, the volume of the discharged liquid calculated by 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; constant displacement The hydraulic pump is called a metering pump.
The working pressure of the waste paper baler The output pressure of the hydraulic pump of the waste paper baler is actually called the working pressure. Regardless of the flow rate of the hydraulic pump, the working pressure depends on the size of the external load and the pressure loss on the discharge line. According to the test standard, the hydraulic pump of the waste paper baler is called the rated pressure of the hydraulic pump under normal working conditions.
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 limited 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 levels.
