The hydraulic system of the waste paper baler is the main cause of noise. For example, the valve core is stuck or stuck in the valve due to improper fit between the spool valve and the valve hole, or the contact between the cone valve and the valve seat is stuck by dirt, or the orifice is blocked or fails. The movement in the hole is not effective, causing system pressure fluctuations and noise. There is also improper adjustment of the reversing valve spool of the waste paper baler, which causes the reversing valve spool to move too fast, causing reversing shock, and thus generating noise and vibration.

Finally, the vibrating oil pipe of waste paper packaging machinery is slender and has many elbows without being fixed. When the oil flows through, especially when the flow rate is high, it is easy to cause the pipe to shake, the rotating part of the motor and the hydraulic pump are unbalanced, or during installation. Poor time alignment or loose couplings can cause vibration and noise. The noise of the waste paper baler generally appears in the hydraulic cylinder, and the noise caused by the air entering the cylinder. Solution: Use the air release valve to release the air. Dip the oil return pipe into the oil surface.

The waste paper baler features high-density packaging, beautiful package shape, easy installation, simple operation, convenient maintenance, small footprint, and the hydraulic system adopts a combination of high and low pressure, efficient and fast. https://www.nkbaler.com
