"Boiling" refers to the phenomenon that the temperature of the diesel engine of the loader is too high and the coolant boils and steams in the water tank. The causes, prevention and elimination methods of "boiling" of diesel engine mainly include:

1.散熱器散熱管(芯子)內(nèi)壁結(jié)垢過厚，影響散熱。使用中應(yīng)注意加注潔凈的冷卻水;并定期水箱中的水垢;

1. The inner wall of radiator cooling pipe (core) is too thick, which affects heat dissipation. Pay attention to filling clean cooling water during use; And regularly remove the scale in the water tank;

2.散熱器或冷卻系漏水，造成冷卻液不足。檢查漏水的原因，排除故障后加足冷卻水;

2. The radiator or cooling system leaks water, resulting in insufficient coolant. Check the cause of water leakage and add enough cooling water after troubleshooting;

3.氣缸墊或氣缸套損壞，氣缸內(nèi)的高壓氣體進(jìn)入水冷卻系，導(dǎo)致水箱“翻泡”“開鍋”(此種情況下，多伴有柴油機(jī)機(jī)油乳化現(xiàn)象)。應(yīng)檢修氣缸墊或氣缸套是否損壞，必要時進(jìn)行更換;

3. The cylinder gasket or cylinder liner is damaged, and the high-pressure gas in the cylinder enters the water cooling system, resulting in "bubbling" and "boiling" (in this case, it is often accompanied by emulsification of diesel engine oil). Check whether the cylinder gasket or cylinder liner is damaged and replace it if necessary;

4.水泵損壞，冷卻水不循環(huán)或循環(huán)強(qiáng)度不足。應(yīng)檢查水泵損壞的原因，必要時更換新水泵;

4. The water pump is damaged, the cooling water does not circulate or the circulation intensity is insufficient. Check the cause of the damage of the water pump and replace it with a new one if necessary;

5.機(jī)器長時間高負(fù)荷工作，風(fēng)扇皮帶過松、風(fēng)速不強(qiáng)，也會出現(xiàn)因過熱而開鍋的現(xiàn)象。應(yīng)合理安排裝載機(jī)的作業(yè)負(fù)荷，防止機(jī)器出現(xiàn)過熱現(xiàn)象。

5. When the machine works under high load for a long time, the fan belt is too loose and the wind speed is not strong, and the boiler will boil due to overheating. The working load of the loader shall be reasonably arranged to prevent overheating of the machine.

6.節(jié)溫器損壞，導(dǎo)致大循環(huán)打不開，引起機(jī)器過熱，應(yīng)更換節(jié)溫器。

6. The thermostat is damaged, resulting in the failure to open the large cycle and overheating of the machine. The thermostat should be replaced.

附注意，在高寒地區(qū)工作的裝載機(jī)也會出現(xiàn)開鍋現(xiàn)象，主要原因為散熱器內(nèi)凍結(jié)，冷卻液無法進(jìn)行大循環(huán)。因此，在高寒地區(qū)使用裝載機(jī)，應(yīng)注意在散熱器前端加保溫裝置。

Note that loaders working in high and cold areas will also boil, mainly due to the freezing in the radiator and the failure of large circulation of coolant. Therefore, when using loaders in alpine areas, attention should be paid to adding thermal insulation devices at the front end of the radiator.
