全自動攪拌車散熱流量較小，冷卻器安裝位置不合理，使係統散熱能力降低全自動攪拌車的冷卻方式有風冷和水冷兩種，用戶可根據實際情況選用，但一般采用風冷較多。有些全自動攪拌車因考慮冷卻器的承壓要求，將冷卻器設置在攪拌係統的回油路上，僅對攪拌係統的油液進行冷卻，因攪拌係統流量較小，因此整個係統冷卻效果差，使係統發熱。
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.
解決的方法：
Solution:
一是可采用獨立冷卻回路，提高冷卻效果。二是將冷卻器設置在係統總回油路上，以加大散熱流量，提高冷卻效果，但此時應注意兩個問題：
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:
第一個問題是冷卻風扇的轉速，冷卻風扇的轉速不能過低，否則將降低冷卻效果，可采用電動機驅動風扇，或在總回油路上設置一低壓驅動馬達，使馬達轉速與散熱流量相匹配，同時還可解決主回路壓力衝擊對冷卻器承壓能力的影響;
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;
第二個問題是如采用電動機驅動風扇，主係統的壓力衝擊對冷卻器承壓能力的影響，此時，可在回油路上與冷卻器並裝一個低壓溢流保護閥或單向閥對冷卻器進行高承壓保護。
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.
此外管路設計、安裝不合理，造成壓力損耗大，使壓力能轉換成熱能在液壓係統設計中，管路的設計與安裝不能忽視，各管路管徑應嚴格按其工作壓力和通過流量進行設計，避免管徑設計過小，造成流速過高，沿程壓力損失過大，引起發熱。
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.
同時，還應注意管路的安裝，既要做到外觀整齊，又要避免管路集聚及管路的急轉彎，影響管路的自然散熱或造成局部壓力損失過大引起發熱。更多相關內容就來kaiyun網站http://www.skar-bnat.com谘詢吧！
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.
