Due to the small heat dissipation flow of the automatic mixer and the unreasonable installation position of the cooler, the heat dissipation capacity of the system is reduced. There are two cooling modes of the automatic mixer: air cooling and water cooling. The user can choose according to the actual situation, but generally air cooling is used more. Due to the pressure bearing requirements of the cooler, some fully automatic mixers set the cooler on the oil return path of the mixing system, only cooling the oil of the mixing system. Because the flow of the mixing system is small, the cooling effect of the whole system is poor, making the system hot.
First, independent cooling circuit can be adopted to improve cooling effect. The second is to set the cooler on the total return oil path of the system to increase the heat dissipation flow and improve the cooling effect, but at this time, two problems should be noted:
The first problem is the speed of the cooling fan. The speed of the cooling fan should not be too low, otherwise the cooling effect will be reduced. The motor can be used to drive the fan, or a low pressure drive motor can be set on the main oil return circuit to match the speed of the motor with the heat dissipation flow. At the same time, it can also solve the impact of the pressure impact of the main circuit on the pressure bearing capacity of the cooler;
The second problem is the impact of the pressure impact of the main system on the pressure bearing capacity of the cooler if the fan is driven by a motor. At this time, a low pressure overflow protection valve or a check valve can be installed on the oil return circuit and the cooler to protect the cooler from high pressure.
In addition, the design and installation of pipelines are unreasonable, resulting in large pressure loss, so that the pressure can be converted into heat energy. In the design of hydraulic system, the design and installation of pipelines cannot be ignored. The pipe diameter of each pipeline should be designed strictly according to its working pressure and flow rate, to avoid the design of pipe diameter is too small, resulting in high flow rate, excessive pressure loss along the pipeline, and heating.
At the same time, attention should also be paid to the installation of the pipeline, which should not only keep the appearance neat, but also avoid the accumulation of the pipeline and the sharp turn of the pipeline, which will affect the natural heat dissipation of the pipeline or cause excessive local pressure loss to cause heating.
