What are the reasons for the heating of the hydraulic oil of the horizontal hydraulic baler
Author : admin Time : 21-04-19 AllPageView : 255

The hydraulic oil is the starting point of the horizontal hydraulic baler. Before using the hydraulic oil of the horizontal hydraulic baler, the hydraulic oil must be kept clean. There are also many people who experience heating of the hydraulic oil during the use of the horizontal hydraulic baler. Today I will give you a brief analysis of what may be the cause.

1. Insufficient precision of components and poor assembly quality, large mechanical friction loss between relative motions, unreasonable design structure of hydraulic components in the system, and poor manufacturing quality. After the oil passes through the valve, its pressure loss is large and 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 to overflow from the overflow valve under high pressure and generate heat during operation. The rules for hydraulic components in the hydraulic system are unreasonable. When the valve is selected, due to its too small size, the energy loss is too large and the system heats up, or the tassel inside the valve is too high to cause noise. 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. The entire flow of the pump overflows under high pressure, resulting in overflow loss and heating, resulting in oil heating.

4. The volume of the fuel tank 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.

5. The matching 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 reduction of the volumetric efficiency of the pump and rapid heating.

6. The working pressure of the hydraulic system is adjusted to be higher than the actual need. Sometimes it is because the seal is too tight, or because the seal is damaged or the leakage increases, the pressure has to be increased to work.

7. The viscosity of the selected oil is improper, the viscosity is large, the viscosity resistance is large, the viscosity is too small, the leakage will increase, and both cases can cause the oil to heat up.

Prior to use, the hydraulic oil may be contaminated by the outside world during the storage process, or errors may occur, so the staff should pay attention to the state of the oil before filling the oil, and if any problems are found, they should be dealt with in time.

The above is the introduction of the reason for the heating of the hydraulic oil of the horizontal hydraulic baler. If you have any questions, please consult Nick Machinery. Contact number 86-29-86031588
