混凝土搅拌车散热系统如何不花钱故障?

概述:搅拌车的罐体运行是通过液压的传动来运作的,液压油长时间在管路中以一定的速度流动,与管壁摩擦,在加上管路中各种阀件的阻力和油泵的做功
搅拌车的罐体运行是通过液压的传动来运作的,液压油长时间在管路中以一定的速度流动,与管壁摩擦,在加上管路中各种阀件的阻力和油泵的做功,液压油被压缩,使液压油产生热量,油温上升。
The tank operation of the mixer truck is operated through hydraulic transmission. The hydraulic oil flows at a certain speed in the pipeline for a long time and rubs with the pipe wall. In addition to the resistance of various valves in the pipeline and the work of the oil pump, the hydraulic oil is compressed, so that the hydraulic oil generates heat and the oil temperature rises.
液压油正常工作,有一定的温度是好事,但是如果超过温度范围,不仅会使整个工作系统不稳定,也会损坏密封件以及加剧液压油氧化变质。
When the hydraulic oil works normally, it is good to have a certain temperature, but if it exceeds the temperature range, it will not only make the whole working system unstable, but also damage the seals and aggravate the oxidation and deterioration of the hydraulic oil.
混凝土搅拌车液压油散热系统一般由以下四个部分组成,其中容易发生故障的就是用来保护整个电路的保险,所以各位开混凝土搅拌车的朋友,在出现此类问题的时候,时间先检查保险是否正常,再进行其他部位的故障排查。
小型搅拌机
The hydraulic oil heat dissipation system of concrete mixer is generally composed of the following four parts, of which the most prone to failure is the insurance used to protect the whole circuit. Therefore, when such problems occur, friends driving concrete mixer should first check whether the insurance is normal, and then troubleshoot other parts.
热交换器类似水箱液压油流过来降温
The heat exchanger is similar to the water tank, and the hydraulic oil flows to cool down
和发动机散热的原理一样,搅拌车利用液压油散热器来进行降温。热交换器(也可以叫做散热油箱)上装的电机驱动风扇进行强制的散热,让液压油保持在正常的工作范围。
Like the principle of engine heat dissipation, the mixer uses the hydraulic oil radiator to cool down. The motor-driven fan installed on the heat exchanger (also known as the heat dissipation oil tank) drives the fan for forced heat dissipation to keep the hydraulic oil within the normal working range.
上面的机械式指针通过检测管路当中的负压,如果出现读数证明液压油滤清器可能出现堵塞,刚开始出现的时候只需要拔掉上面的橡胶塞让指针归零,如果后面还出现读数且拔掉橡胶塞之后还不了的话,就需要更换液压油滤芯了。
The above mechanical pointer detects the negative pressure in the pipeline. If there is a reading, it proves that the hydraulic oil filter may be blocked. At the beginning, just pull out the rubber plug and let the pointer return to zero. If there is a reading later and it cannot be solved after pulling out the rubber plug, it is necessary to replace the hydraulic oil filter element.
电机驱动风扇带走液压油热量
The motor-driven fan takes away the heat of hydraulic oil
电机是整个散热系统当中,为关键的部件,散热效果的好与坏,和电机的转速以及运行的平稳状态有着直接的关系。它由连接车辆电瓶的电控盒直接供电,用电力驱动电机高速运转,来带走热交换器当中的热量,给液压油降温。
The motor is the most critical component in the whole heat dissipation system. The good or bad heat dissipation effect is directly related to the motor speed and the stable state of operation. It is directly powered by the electric control box connected to the vehicle battery and drives the motor to run at high speed to take away the heat in the heat exchanger and cool the hydraulic oil.
温度传感器检测液压油温度
The temperature sensor detects the hydraulic oil temperature
安装在热交换器进油管上的传感器,用来检测进入热交换器中液压油的温度,它是在排除保险故障之后第二个来排除的故障点。
The sensor installed on the oil inlet pipe of the heat exchanger is used to detect the temperature of the hydraulic oil entering the heat exchanger. It is the second fault point to be eliminated after the insurance fault is eliminated.
控制盒是大脑不让液压油高温
The control box keeps the hydraulic oil from being heated
控制盒是整个散热系统当中的大脑,类似于车辆的ECU,温度传感器传递过来的数据经过它的分析,超过预定的温度值之后接通散热电机的电路,让电机运转来带走液压油中的温度。它的上面装有保护整个电路的保险,让控制盒不会轻易损坏。
The control box is the brain of the whole heat dissipation system, which is similar to the ECU of the vehicle. After its analysis, the data transmitted by the temperature sensor exceeds the predetermined temperature value, connect the circuit of the heat dissipation motor and let the motor run to take away the temperature in the hydraulic oil. It is equipped with a fuse to protect the whole circuit, so that the control box will not be easily damaged.
