沼氣發(fā)動機組冷卻液不循環(huán)怎么辦？

沼氣發(fā)動機組在運行中有時會遇到冷卻液不循環(huán)的情況，導致機組出現(xiàn)缸溫升高快、油溫升高而造成突然停機等現(xiàn)象，影響沼氣發(fā)動機組的安全使用。
During the operation of biogas engine group, sometimes the coolant does not circulate, resulting in rapid cylinder temperature rise and sudden shutdown caused by oil temperature rise, which affects the safe use of biogas engine group.

1、沼氣發(fā)動機組水泵故障。檢查水泵作用是否良好，如果發(fā)現(xiàn)水泵傳動齒軸磨損過說明水泵已起不到作用，需要更換后才能循環(huán)正常。
1. Biogas engine set water pump failure. Check whether the water pump works well. If it is found that the water pump transmission gear shaft is worn beyond the limit, it indicates that the water pump has failed to function and needs to be replaced before it can circulate normally.

2、沼氣發(fā)動機組冷卻液液面過低或不符合規(guī)定。液面過低可直接造成冷卻液溫度升高使冷卻液不循環(huán)，冷卻液按規(guī)定是50%防凍液+50%軟化水+DCA4，若不符合規(guī)定將會造成管路堵塞，管壁內(nèi)產(chǎn)生銹跡，使冷卻液無法正常循環(huán)。
2. The coolant level of biogas engine set is too low or does not meet the regulations. Low liquid level can directly cause the coolant temperature to rise and the coolant will not circulate. The coolant is 50% antifreeze + 50% demineralized water + dca4 as specified. If it does not meet the regulations, it will cause pipeline blockage and rust in the pipe wall, making the coolant unable to circulate normally.
3、沼氣發(fā)動機組燃燒室內(nèi)裝有節(jié)溫器，目的在于控制發(fā)動機燃燒室溫度，節(jié)溫器必須在規(guī)定溫度完全打開有助于小循環(huán)，如果沒有節(jié)溫器，冷卻液不能保持循環(huán)溫度，可能會產(chǎn)生低溫報警。
3. A thermostat is installed in the combustion chamber of the biogas engine set to control the temperature of the engine combustion chamber. The thermostat must be fully opened at the specified temperature to facilitate small circulation. If there is no thermostat, the coolant cannot maintain the circulation temperature, and a low temperature alarm may be generated.
4、沼氣發(fā)動機組冷卻系統(tǒng)中混有空氣，造成管路不暢通，膨脹水箱上吸氣閥、排氣閥損壞也直接影響循環(huán)，這時應經(jīng)常檢查它們的壓力值是否符合規(guī)定，吸氣壓力是10kpa，排氣壓力是40kpa，除次之外排氣管路是否暢通也是影響循環(huán)的重要原因。
4. There is air mixed in the cooling system of biogas engine set, resulting in blocked pipeline. The damage of suction valve and exhaust valve on the expansion water tank also directly affects the circulation. At this time, it is necessary to often check whether their pressure values meet the regulations. The suction pressure is 10KPA and the exhaust pressure is 40kpa. In addition, whether the exhaust pipeline is unblocked is also an important reason affecting the circulation.
