高温的夏天，工地上的室外温度往往超过40度。本来长时间的施工就会使小型搅拌机的发动机发热、液压油温度上升，而炎热的酷暑，更加剧了发动机和液压油温度过高的情况。那么，炎热的夏天我们该采取什么措施给搅拌机及其发动机做保养呢？

In hot summer, the outdoor temperature on the construction site often exceeds 40 ℃. Originally, long-term construction will cause the engine of the mixer to heat up and the temperature of the hydraulic oil to rise. However, the hot summer heat will further aggravate the situation that the temperature of the engine and the hydraulic oil is too high. So, what measures should we take to maintain the mixer and its engine in hot summer?

1、关于搅拌机发动机温度的控制

1. Control of mixer engine temperature

一般情况下，发动机温度过高的原因是发动机保养不到位，比如发动机缺少冷却液，花絮等杂质附着散热器导致发动机的散热效果差等。为了将搅拌机发动机的温度控制在正常范围内，务必遵循以下几条规制：必须使用正规厂家生产的防冻液；确保防冻液处于有效期内、液量充足。

In general, the reason for the high engine temperature is that the engine maintenance is not in place, such as the lack of coolant in the engine, and the poor heat dissipation effect of the engine due to the attachment of impurities such as trivia to the radiator. In order to control the temperature of the mixer engine within the normal range, the following regulations must be followed: antifreeze produced by regular manufacturers must be used; Ensure that the antifreeze is within the validity period and the amount of antifreeze is sufficient.

如果因为故障导致亏液现象的出现，也要保证水的添加量在冷却液总量的10%以下。天气炎热时，水分蒸发特别快，水分蒸发之后缺液情况会再次出现，而且在夏季施工高峰期，搅拌机连续工作的情况比比皆是，所以我们不以水作为搅拌机发动机的冷却液。

In case of liquid shortage due to fault, the water addition amount shall be less than 10% of the total amount of coolant. When the weather is hot, the water evaporates very quickly, and the lack of liquid will occur again after the water evaporates. Moreover, during the summer construction peak, the continuous operation of the mixer is common, so we do not recommend using water as the coolant of the mixer engine.

在春季来临时，应在发动机的散热器前面加纱网从而保持散热器外部的清洁，还要注意定期清洁这个纱网。而在夏季，应拆除纱网方便发动机散热器的空气流动。此外，建议广大客户在搅拌机施工时尽量提高混凝土供应的连续性，减少搅拌机在高温暴晒环境下的运转时间。

When spring comes, a gauze shall be added in front of the radiator of the engine to keep the outside of the radiator clean, and the gauze shall be cleaned regularly. In summer, the gauze should be removed to facilitate the air flow of the engine radiator. In addition, it is suggested that customers should try their best to improve the continuity of concrete supply during the construction of the mixer, so as to reduce the operation time of the mixer under the high-temperature exposure environment.

2、关于搅拌机液压油的温度

2. About the temperature of the hydraulic oil of the mixer

夏季的高温环境已达到搅拌机液压系统正常工作温度的下限，而泵送工作又必然会造成液压油温度的迅速升高。油温升高会降低液压油的黏度，导致润滑效果变差。

The high temperature environment in summer has reached the lower limit of the normal working temperature of the hydraulic system of the mixer, and the pumping work will inevitably cause the rapid rise of the hydraulic oil temperature. The increase of oil temperature will reduce the viscosity of hydraulic oil, resulting in poor lubrication effect.

与此同时，在热胀冷缩的作用下，液压系统的一些零部件磨损加剧。所以，越在高温环境下工作更需要严格控制液压油的温度，选用合适型号的液压油且定期更换液压油，确保液压油的品质高、清洁。

At the same time, under the effect of thermal expansion and cold contraction, the wear of some parts of the hydraulic system is intensified. Therefore, it is more necessary to strictly control the temperature of hydraulic oil when working in a high temperature environment, select the appropriate type of hydraulic oil and replace the hydraulic oil regularly to ensure the high quality and cleanness of the hydraulic oil.

对于闭式液压系统的泵送单元，要随时观察、保证液压油重视散热器正常工作，在必要时可以向主油缸缓慢喷淋清水、协助散热；而对于开式液压系统的泵送单元，在必要时可以在主回油管或散热器上缓慢喷淋清水、协助降温。更多相关注意事项就来我们网站https://www.zishangliaojiaobanji.cn做咨询吧！

For the pumping unit of the closed hydraulic system, it is necessary to observe and ensure that the hydraulic oil attaches importance to the normal operation of the radiator at any time. When necessary, it can slowly spray clean water to the main oil cylinder to assist in heat dissipation; For the pumping unit of the open hydraulic system, if necessary, water can be slowly sprayed on the main oil return pipe or radiator to help cool down.
