  他的一位前同事近打电话说,他的中科自上料搅拌车冷却风扇坏了,影响了运营。有人问我原因是什么。在询问了过失和他的解决办法后,我怀疑过失是被保险烧毁的。更换新保险后,故障解决了。今天小编和我们谈谈水泥搅拌机液压油冷却系统。
  One of his former colleagues recently called to say that his cooling fan had broken down, affecting operations. I was asked why. After asking about the fault and his solution, I suspect that the fault was burned by the insurance. After replacing the new insurance, the problem was solved. Today Xiaobian will talk about the hydraulic oil cooling system of the cement mixer with us.
  坦克运行的水泥搅拌机是由液压传动,液压油在很长一段时间内以一定速度在管道流动,与管子的壁摩擦,除了管道在各种阀门阻力和油泵的工作,压缩液压油,液压油会产生热量,油温上升。液压油工作正常,一定的温度是一件好事,但如果温度范围太大,不仅会使整个工作系统不稳定,还会损坏油封,加剧液压油氧化变质。
  The tank operated cement mixer is driven by hydraulic pressure. The hydraulic oil flows in the pipeline at a certain speed for a long time, and rubs against the wall of the pipeline. In addition to the pipeline resistance in various valves and the work of the oil pump, the hydraulic oil will generate heat and the oil temperature will rise by compressing the hydraulic oil. If the hydraulic oil works normally, a certain temperature is a good thing, but if the temperature range is too large, it will not only make the whole working system unstable, but also damage the oil seal, aggravating the oxidation and deterioration of the hydraulic oil.
  混凝土搅拌车液压油冷却系统一般由下列四个部分组成,其中容易失败是保护整个电路的保险,所以你打开混凝土搅拌车,朋友这样的问题的时候,次检查是否正常的保险,然后其他部分的故障诊断。
  The hydraulic oil cooling system of the concrete mixer is generally composed of the following four parts, of which the most likely failure is to protect the entire circuit, so when you open the concrete mixer, friends and other problems, check whether the insurance is normal for the first time, and then the fault diagnosis of other parts.
  热交换器就像一个液压油箱,来冷却它
  The heat exchanger is like a hydraulic tank to cool it
  就像发动机散热一样,混凝土搅拌机使用液压油散热器冷却。热交换器(又称散热箱)装有电机驱动的风扇,强制散热,使液压油保持在正常工作范围内。
  Just as the engine heats, the concrete mixer is cooled by a hydraulic oil radiator. The heat exchanger (also known as heat sink) is equipped with a fan driven by a motor, which forces heat dissipation to keep the hydraulic oil within the normal working range.
  机械指针通过检测管道的负压,证明液压油过滤器堵塞可能发生如果有读数,起初只需要删除指针为零的橡皮塞,如果仍然出现后阅读和把橡皮塞仍解决不了需要更换液压油过滤器。
  By detecting the negative pressure of the pipeline, the mechanical pointer proves that the hydraulic oil filter may be blocked. If there is a reading, at first only the rubber plug with zero pointer needs to be deleted. If there is still a reading and the rubber plug still cannot be solved, the hydraulic oil filter needs to be replaced.
  马达驱动的风扇带走了液压油的热量
  The fan driven by the motor takes away the heat of the hydraulic oil
  电机是整个冷却系统中重要的部分。冷却效果的好坏直接关系到电机的转速和运行状态的好坏。它直接由一个与汽车电池相连的电箱供电,这个电箱驱动一个电机高速运转,将热量从热交换器中带走,并冷却液压液。
  The motor is the most important part of the whole cooling system. The cooling effect is directly related to the speed and running state of the motor. It is powered directly by an electric box connected to the car battery, which drives a motor to run at high speed, takes heat away from the heat exchanger and cools the hydraulic fluid.

  温度传感器检测液压油的温度
  Temperature sensor detects the temperature of hydraulic oil
  在换热器进水管上安装传感器,检测进入换热器的液压油的温度。
  A sensor is installed on the water inlet pipe of the heat exchanger to detect the temperature of the hydraulic oil entering the heat exchanger.
  控制箱是控制液压油不受热的大脑
  The control box is the brain that controls the hydraulic oil not to be heated
  控制箱是整个冷却系统的大脑,类似于车辆的ECU。对温度传感器传递的数据进行分析。超过温度值后,连接冷却电机回路,运行电机带走液压油中的温度。它的顶部有保险,以保护整个电路,使控制箱不容易损坏。
  The control box is the brain of the whole cooling system, similar to the ECU of the vehicle. Analyze the data transmitted by the temperature sensor. After the temperature value is exceeded, connect the cooling motor circuit, and run the motor to take away the temperature in the hydraulic oil. It has a safety cover on the top to protect the whole circuit, so that the control box is not easy to damage.
  好了,说一下它的原理,冷却系统故障后电机不运行,经济、省时的故障排除顺序请按以下顺序检查保险——更换温度传感器——更换电机——更换控制箱
  Well, let's talk about its principle. After the cooling system fails, the motor does not run. For the most economical and time-saving troubleshooting sequence, please check the fuse in the following order - replace the temperature sensor - replace the motor - replace the control box
