冷却方法有两个,一个是在系列成型机的液压系统的主机,主要安装在回水管上,冷却后与高温液压油循环系统中,和冷却器的出口连接槽;液压系统独立于成型机主机，并有单独的冷却循环管路。主机旁边安装液压站，齿轮泵作为循环泵。冷却器风机使周围的空气流动，带走冷却器散热器内的油热，从而达到冷却油的目的。这种方法，油冷却技术有其优点和缺点，优点是结构设计简单，占用空间少，维修方便，成本低，所以现在是80%的液压控制系统通过冷却的方式，缺点是企业现场施工工作和环境影响研究相对严重，而且室内温度变化产生的降温效果不佳，特别是在夏季，现场教学环境分析温度较高，石油管道和周围空气冷却器温差小,热量交换学习效果不好,冷却效率大大降低,同时也影响学生的工作安全环境因素,灰尘大,能使冷却器翅片挂一层灰尘,阻碍了石油和环境,热因此，冷却效果需要有一个显著的下降。
There
are two cooling methods. One is the main engine of the hydraulic system
of the series molding machine, which is mainly installed on the return
water pipe. After cooling, it is connected to the high-temperature
hydraulic oil circulation system and the outlet connection groove of the
cooler; The hydraulic system is independent of the molding machine host
and has a separate cooling circulation pipeline. Install a hydraulic
station next to the host, and use a gear pump as a circulating pump. The
cooler fan allows the surrounding air to flow and take away the oil
heat inside the cooler radiator, thereby achieving the purpose of
cooling the oil. This method, oil cooling technology, has its advantages
and disadvantages. The advantages are simple structural design, less
space occupation, convenient maintenance, and low cost. Therefore, 80%
of hydraulic control systems are now cooled. The disadvantages are that
the on-site construction work and environmental impact research of
enterprises are relatively strict, and the cooling effect caused by
indoor temperature changes is not good, especially in summer. The
analysis of the on-site teaching environment shows that the temperature
is high, The temperature difference between the oil pipeline and the
surrounding air cooler is small, the heat exchange learning effect is
not good, the cooling efficiency is greatly reduced, and it also affects
the work safety and environmental factors of students. The large dust
can cause a layer of dust on the cooler fins, which hinders the oil and
the environment. Therefore, the cooling effect needs to be significantly
reduced.
二、水冷却器温度控制
2、 Temperature control of water cooler
水冷器用于液压系统的冷却，目前仍在国内一些企业中使用。它要求安装设计一个水冷循环管理系统，配备一个水冷器(油-水热交换器)，管道泵，开发一个大型水箱并通过相应的连接。在正常工作条件下，冷却器的效果比较好，但也有很多缺点，如一次性投资成本高，除垢、冬季排水、管道防锈的维护工作量大，无端增加了维护工作量。与此同时,为了节约用水,冷却水只能选择循环冷却水箱,为了更好的完成冷却的冷却效果
Water
coolers are still used for cooling hydraulic systems in some domestic
enterprises. It requires the installation and design of a water cooling
cycle management system, equipped with a water cooler (oil water heat
exchanger), pipeline pump, development of a large water tank and
corresponding connections. Under normal working conditions, the effect
of the cooler is relatively good, but there are also many drawbacks,
such as high one-time investment costs, large maintenance workload for
descaling, winter drainage, and pipeline rust prevention, which
unnecessarily increases maintenance workload. At the same time, in order
to save water, the cooling water can only be selected as a circulating
cooling water tank, in order to better achieve the cooling effect of
cooling
