全自动搅拌车散热流量较小，冷却器安装位置不合理，使系统散热能力降低全自动搅拌车的冷却方式有风冷和水冷两种，用户可根据实际情况选用，但一般采用风冷较多。有些全自动搅拌车因考虑冷却器的承压要求，将冷却器设置在搅拌系统的回油路上，仅对搅拌系统的油液进行冷却，因搅拌系统流量较小，因此整个系统冷却效果差，使系统发热。
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.
的方法：
Solution:
一是可采用独立冷却回路，提高冷却效果。二是将冷却器设置在系统总回油路上，以加大散热流量，提高冷却效果，但此时应注意两个问题：
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:
个问题是冷却风扇的转速，冷却风扇的转速不能过低，否则将降低冷却效果，可采用电动机驱动风扇，或在总回油路上设置一低压驱动马达，使马达转速与散热流量相匹配，同时还可主回路压力冲击对冷却器承压能力的影响;
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;
第二个问题是如采用电动机驱动风扇，主系统的压力冲击对冷却器承压能力的影响，此时，可在回油路上与冷却器并装一个低压溢流保护阀或单向阀对冷却器进行高承压保护。
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.
此外管路设计、安装不合理，造成压力损耗大，使压力能转换成热能在液压系统设计中，管路的设计与安装不能忽视，各管路管径应严格按其工作压力和通过流量进行设计，避免管径设计过小，造成流速过高，沿程压力损失过大，引起发热。
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.
同时，还应注意管路的安装，既要做到外观整齐，又要避免管路集聚及管路的急转弯，影响管路的自然散热或造成局部压力损失过大引起发热。更多相关内容就来我们网站http://www.zkzdsljbc.com咨询吧！
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.
