Hydraulic oil is the starting point of the waste paper baler operation. Before using the waste paper baler hydraulic oil, it is necessary to keep the hydraulic oil clean. Before use, the hydraulic oil may be contaminated by the outside during the storage process, or there may be faults. Therefore, pay attention to investigate the oil condition before filling the oil, and deal with it in time if any problems are found. The waste paper baler factory analyzes the reasons for the heating of hydraulic oil for you:
The accuracy of the components is poor and the quality of the equipment is poor. The mechanical conflict between relative motions is lost. The planned structure of the hydraulic components in the system is unreasonable and the production quality is poor. After the oil passes through the valve, the excitation is large and internal leakage is severe. The unloading circuit in the system is faulty, perhaps because the unloading circuit is not set, and the oil pump cannot unload when the operation is stopped. The entire flow of the pump overflows under high pressure, and the overflow rate generates heat, which causes the oil to heat up.
The fixed pump oil supply system with the capacity of the oil pump selected according to the fast forward speed will cause most of the remaining flow to overflow from the overflow valve under high pressure and generate heat during operation. The standard selection of hydraulic components in the hydraulic system is reasonable. When selecting the valve, because the standard is too small, the formation energy loss is too large and the system heats up, or the flow rate is too high to cause noise. When the pump flow is too large when the pump is selected, the remaining oil will overflow from the overflow valve and cause heat.
Common failures and solutions of mechanical devices of waste paper baler
The waste paper baler will inevitably have various problems during the working process. If an abnormal situation is found, the work should be stopped, the cause should be found, and the work should be carried out after the fault is eliminated.
Problems with oil pumps:
1. Insufficient or no pressure on the oil pump
Cause of failure: oil pump body, oil distribution plate wear or plunger damage
Solution: overhaul the oil pump or replace with a new pump
2. The oil pump is noisy
Causes of failure: oil pump suction, filter screen blocked, oil suction pipe or pump inlet blocked, plunger broken, bearing chipped
Solution: clean or replace the filter screen, clean the pipeline; replace the new plug, bearing
3. No action after the oil pump is started
The spool of the overflow valve is stuck, and the pressure regulating handle is loose
Clean the overflow valve, check the spool and spring, tighten the adjustment handle
