The waste paper baler has to go through a series of tests before leaving the factory. After the test machine is successful, it can meet the factory requirements. The waste paper baler test machine is mainly divided into no-load test machine and load test machine.
1. No-load test machine
Turn on the power of the waste paper baler, loosen the system overflow valve, make the system overflow safely, start the motor (using the method of stopping after starting), and observe whether the rotation of the motor is consistent with the rotation of the oil pump sign.
Start the motor and observe whether the oil pump is stable and reliable during operation, and whether there is any significant noise in the pump. If not, test machine operation can be carried out.
Gradually adjust the overflow valve handle of the waste paper hydraulic baler so that the pressure value is about 8Mpa. Operate according to the order of operation, and single-act each cylinder to observe whether it runs smoothly and without vibration.
2. Load test machine
(1) The load test machine can be performed after the operation of the single cylinder is familiar.
(2) Adjust the pressure of the waste paper hydraulic baler system, do several baling sequences according to the operating sequence, and add materials to the compression chamber. The load test adopts the physical packaging form, pressing 1 to 2 bales and placing them in the cylinder of each waste paper hydraulic baler After the stroke is in place, keep the pressure for 3~5 seconds respectively, and perform a pressure test on the system to observe whether there is any oil leakage. If there is, remove it after the system is depressurized.
