随着经济的快速发展，建筑行业异常红火，投资搅拌车作业的老板们为了尽快收回成本，追求利益增长的同时会缩短工期，水泥自上料搅拌车日夜连续作业，因此，出现了水泥自上料搅拌车的使用问题。自上料水泥搅拌车冷却器冷却效果降低，使油液温升，系统发热冷却器冷却效果降低，可能由以下原因引起：

With the rapid development of the economy, the construction industry is booming. In order to recover the cost as soon as possible, the owners who invest in the operation of the mixing truck will shorten the construction period while pursuing the growth of interests. The cement self-loading mixing truck works continuously day and night. Therefore, there is a problem of using the cement self-loading mixing truck. The cooling effect of the cooler of the self-feeding cement mixer truck is reduced, causing the oil temperature to rise, and the cooling effect of the system heating cooler is reduced, which may be caused by the following reasons:

①冷却器内部堵塞或表面污物较多，造成冷却器装置开启，冷却器过流量降低，使散热流量减少，或冷却器通风不良，使冷却器的冷却传热系数降低，冷却效果降低，因此，水泥自上料搅拌车在使用中一定要定期检查，疏通冷却器，定期对冷却器表面污物进行，保证冷却器的内部畅通和外部清洁，以保证冷却器的冷却效果。

① The internal blockage of the cooler or a lot of dirt on the surface will cause the cooler safety device to open, the cooler overflow will be reduced, the cooling flow will be reduced, or the cooler ventilation will be poor, and the cooling heat transfer coefficient of the cooler will be reduced, and the cooling effect will be reduced. Therefore, the cement self-feeding mixer must be regularly checked during use, dredge the cooler, and regularly clean the dirt on the surface of the cooler, Ensure the internal smoothness and external cleanness of the cooler to ensure the cooling effect of the cooler.

②冷却器阀或单向阀的开启压力低于标准值，使冷却器保护装置在冷却器未堵塞时开启，产生溢流分流，使冷却器散热流量减少，因此，冷却器在使用前，一定要正确调整保护装置的开启压力，在使用中要定期检查、校正保护装置的开启压力值。

② The opening pressure of the safety valve or check valve of the cooler is lower than the standard value, which causes the safety protection device of the cooler to open when the cooler is not blocked, resulting in overflow diversion and reducing the cooling flow of the cooler. Therefore, the opening pressure of the safety protection device must be correctly adjusted before the cooler is used, and the opening pressure value of the safety protection device must be regularly checked and corrected during use.

此外水泥自上料搅拌车液压系统的内泄，包括液压搅拌车、液压缸、液压马达和液压阀的内泄，压力油在泄漏过程中，压力下降，温度升高。如果系统的内泄增加，会引起油温升高，系统过热，严重时，会使系统压力下降，搅拌车送无力，搅拌车送排量降低，搅拌无力，搅拌转速下降等。

In addition, the internal leakage of the hydraulic system of the cement self-feeding mixer truck includes the internal leakage of the hydraulic mixer truck, hydraulic cylinder, hydraulic motor and hydraulic valve. During the leakage of the pressure oil, the pressure drops and the temperature rises. If the internal leakage of the system increases, the oil temperature will rise, the system will overheat, and in serious cases, the system pressure will drop, the mixer truck delivery capacity will be reduced, the mixer truck delivery capacity will be reduced, the mixer will be weak, and the mixing speed will drop.

因此，要定期检查这些元件，定期更换相应的密封元件，及时对已损坏、拉伤的零件进行更换或修理，甚更换相应的液压元件，从而避免由于元件泄漏而造成的系统发热。更多相关使用事项就来我们网站http://www.sdzkjf.cn咨询吧！

Therefore, these components should be checked regularly, corresponding sealing components should be replaced regularly, damaged and strained parts should be replaced or repaired in time, and even corresponding hydraulic components should be replaced, so as to avoid system heating caused by component leakage.
