小型混凝土搅拌车液压系统发热的危害

来源:http://www.zkzdsljbc.com/ 时间:2023-02-24

小型混凝土搅拌车液压系统的发热,直接影响搅拌车的正常工作,发热现象所造成的危害,主要有以下几点:
The heating of the hydraulic system of the small concrete mixer directly affects the normal operation of the mixer. The main hazards caused by the heating phenomenon are as follows:
(1)工作液体的温度升高后,使工作液体的黏度下降,泵的泄漏增加,泵的实际流量有所下降;
(1) When the temperature of the working liquid increases, the viscosity of the working liquid decreases, the leakage of the pump increases, and the actual flow of the pump decreases;
(2)液压系统及元件的密封件在高温下变质,弹性变性能力降低,使密封性能降低,甚密封失效,使泄漏增加;
(2) The seals of the hydraulic system and components deteriorate under high temperature, and the elastic denaturation ability is reduced, which reduces the sealing performance, even the sealing failure, and increases the leakage;
(3)当液压阀件的阀芯、阀体材料不同、热膨胀系数不同时,阀芯、阀体之间因热膨胀而出现阀芯卡死现象,致使小型混凝土搅拌车不能工作;
(3) When the material of valve core and valve body of hydraulic valve is different, and the coefficient of thermal expansion is different, the valve core and valve body are stuck due to thermal expansion, resulting in the small concrete mixer can not work;

(4)工作液体的黏度下降时,使工作液体的润滑性能降低,液压元件的磨损加快,加速了元件的磨损失效,缩短了元件的使用寿命。
(4) When the viscosity of the working fluid decreases, the lubricating performance of the working fluid decreases, the wear of the hydraulic components accelerates, the wear failure of the components is accelerated, and the service life of the components is shortened.
为了尽量避免上述现象的发生,有些小型混凝土搅拌车在使用一定时间后,不得不停下来,使系统降温,从而降低了小型混凝土搅拌车的开机率,影响了施工进度。因此,应针对系统发热原因,采取相应措施,控制液压系统的温度,保证混凝土搅拌车的正常使用。更多相关内容就来我们网站http://www.zkzdsljbc.com咨询吧!
In order to avoid the above phenomena as much as possible, some small concrete mixers have to stop after a certain period of use to cool the system, thus reducing the start-up rate of small concrete mixers and affecting the construction progress. Therefore, corresponding measures should be taken to control the temperature of the hydraulic system and ensure the normal use of the concrete mixer truck according to the heating causes of the system.
