Eight reasons for the heating of the hydraulic oil of the waste paper baler

Dec 31, 2020

Guide: Hydraulic oil is the starting point of the waste paper baler. Before using the waste paper baler hydraulic oil, keep the hydraulic oil clean. Before use, the hydraulic oil may be contaminated by the outside during the storage process, or there may be errors. Therefore, pay attention to the state of the oil before filling the oil. If you find any problems, you should deal with it in time. The waste paper baler factory analyzes the reasons for the heating of hydraulic oil for you:


   Hydraulic oil is the starting point of the waste paper baler. Before using the waste paper baler hydraulic oil, keep the hydraulic oil clean. Before use, the hydraulic oil may be contaminated by the outside during the storage process, or there may be errors. Therefore, pay attention to the state of the oil before filling the oil. If you find any problems, you should deal with it in time. The waste paper baler factory analyzes the reasons for the heating of hydraulic oil for you:

1. Insufficient precision of components and poor assembly quality, large mechanical friction loss between relative movements, unreasonable design structure of hydraulic components in the system, and poor manufacturing quality. Mineral water bottle packing machine This product has the characteristics of good rigidity, toughness and stability, beautiful appearance, convenient operation and maintenance, safety and energy saving, and low investment cost of equipment basic engineering. It is widely used in all kinds of waste paper factories, waste recycling companies and other units and enterprises. It is suitable for the packaging and recycling of waste paper, plastic straw, etc. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower, and reduce transportation costs. After the oil passes through the valve, the pressure loss is large and the internal leakage is serious.

2. 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 excess flow (unit: cubic meters per second) to overflow from the overflow valve under high pressure and generate heat during operation. The selection of hydraulic components in the hydraulic system is unreasonable. When the valve is selected, due to the too small size, the energy loss is too large and the system heats up, or the flow rate is too high and noise is caused. When the pump flow is too large when the pump is selected, the excess oil will overflow from the overflow valve and cause heat.

 3. The unloading circuit in the system fails or because the unloading circuit is not set, the oil pump cannot unload when it stops working, and the flow of the pump overflows under high pressure, resulting in overflow loss and heat generation, resulting in oil heating.

4. The system pipeline is too thin or too long, excessively bent, local pressure loss and pressure loss along the way are large, there are redundant hydraulic circuits or redundant hydraulic components in the hydraulic system.

5. The oil tank volume is too small, the heat dissipation area is not enough, the oil cooling device is not installed, or although there is a cooling device, its capacity is too small. There are 4 sets of feeding devices for the scrap metal baler, each of which corresponds to a baling head. Each set includes a baling line conveying device and a baling line reverse tension device. The main rail seat of the waste paper hydraulic baler is mainly composed of two wear-resistant steel rails on the surface. The wheels of the compression frame are guided to run along the outer sides of the two tracks, and hydraulic cylinders that push the compression frame to operate are arranged in them. In addition, there is a complete set of hydraulic stations in addition to mechanical components. It can be seen from the above description that various movements of the waste paper hydraulic baler are completed by fluid power.

6. The fitting clearance of the matching parts is too small, or the clearance is too large after use and wear, and the internal and external leakage is large, resulting in large volume loss, such as the volumetric efficiency of the pump, and rapid heating.

7. The working pressure of the hydraulic system is adjusted higher than the actual need. With the increasing awareness of environmental protection, the waste paper baler has played a very important role. It can reuse some waste paper and is more and more accepted by everyone. In constant innovation, we are constantly following the development of some foreign advanced technologies. Sometimes it is because the seal is too tight, or the seal is damaged or leaked and the pressure is increased to work.

8. Choosing the oil with improper viscosity, high viscosity, high viscous resistance, too small viscosity, leakage, both cases can cause the oil to heat up.
