沼气发动机组冷却液不循环怎么办?

返回 2021.08.25 来源:http://www.huannengpower.com
沼气发动机组在运行中有时会遇到冷却液不循环的情况,导致机组出现缸温升高快、油温升高而造成突然停机等现象,影响沼气发动机组的安全使用。
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.

Biogas Generator Set 
1、沼气发动机组水泵故障。检查水泵作用是否良好,如果发现水泵传动齿轴磨损过说明水泵已起不到作用,需要更换后才能循环正常。
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、沼气发动机组冷却液液面过低或不符合规定。液面过低可直接造成冷却液温度升高使冷却液不循环,冷却液按规定是50%防冻液+50%软化水+DCA4,若不符合规定将会造成管路堵塞,管壁内产生锈迹,使冷却液无法正常循环。
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、沼气发动机组燃烧室内装有节温器,目的在于控制发动机燃烧室温度,节温器必须在规定温度完全打开有助于小循环,如果没有节温器,冷却液不能保持循环温度,可能会产生低温报警。
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、沼气发动机组冷却系统中混有空气,造成管路不畅通,膨胀水箱上吸气阀、排气阀损坏也直接影响循环,这时应经常检查它们的压力值是否符合规定,吸气压力是10kpa,排气压力是40kpa,除次之外排气管路是否畅通也是影响循环的重要原因。
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.
