沼气发电机组的水温和转速的两大误区

返回 2022.08.31 来源:http://www.huannengpower.com
由于沼气发电机组是一个高能耗的机器,用户在使用时肯定要考虑它的燃油消耗问题。许多用户可能都认为发电机组的水温越低越好,转速越低越省油。其实这都是错误的认识。
As the biogas generator unit is a high energy consumption machine, the user must consider its fuel consumption when using it. Many users may think that the lower the water temperature of the generator set, the better, and the lower the speed, the more fuel-saving. In fact, this is a wrong understanding.
沼气发电机的水温使用要求有明确规定,但一些操作人员却喜欢把出水温度调得很低,有的接近出水温度的下限值,有的还不到下限值。他们认为水温低,水泵中不会出现气蚀现象,冷却水(液)就不会中断,使用中有保险系数。
The water temperature requirements of biogas generator are clearly specified, but some operators like to adjust the outlet water temperature very low. Some are close to the lower limit of the outlet water temperature, and some are less than the lower limit. They believe that if the water temperature is low, cavitation will not occur in the water pump, the cooling water (liquid) will not be interrupted, and there is an insurance factor in use.
其实水温只要不超过95℃就不会发生气蚀,冷却水(液)也不会中断。相反,如果水温过低,对沼气发动机的工作有害。一是温度低,气缸内沼气燃烧条件恶化,燃料雾化不良,着火后燃期增长,发动机工作易粗暴,加剧曲轴轴承、活塞环等零部件的损坏,功率降低,经济性降低。
In fact, as long as the water temperature does not exceed 95 ℃, cavitation will not occur and the cooling water (liquid) will not be interrupted. On the contrary, if the water temperature is too low, it is harmful to the operation of the biogas engine. First, the temperature is low, the combustion conditions of biogas in the cylinder are deteriorated, the fuel atomization is poor, the combustion period after ignition is increased, the engine is easy to work rough, which aggravates the damage of crankshaft bearings, piston rings and other parts, reduces the power and reduces the economy.
二是燃烧后的水气易冷凝在缸壁上,造成金属腐蚀。三是来燃烧的沼气可能稀释机油,使润滑情况变坏。四是燃料燃烧不完全而形成胶质,使活塞环卡在活塞环槽内,气门卡住,压缩终了时气缸内压力降低。五是水温过低机油温度也低,机油变稠,流动性变差,机油泵泵油量少,以致发电机组供油不足,加上曲轴轴承间隙变小,润滑不良。
Second, the water vapor after combustion is easy to condense on the cylinder wall, causing metal corrosion. Third, the biogas from combustion may dilute the engine oil and deteriorate the lubrication. Fourth, the fuel combustion is not complete and the gum is formed, so that the piston ring is stuck in the piston ring groove, the valve is stuck, and the pressure in the cylinder is reduced at the end of compression. Fifth, the water temperature is too low, the oil temperature is also low, the oil is thickened, the fluidity is poor, and the oil pump pump has less oil, resulting in insufficient oil supply for the generator set. In addition, the crankshaft bearing clearance is small, and the lubrication is poor.
许多操作员不愿沼气发电机在使用转速下工作,他们认为发电机转速低些不会出故障。其实,过低的转速也会带来一些不良后果:
Many operators do not want the biogas generator to work at the operating speed. They think that the generator will not fail if the speed is lower. In fact, too low rotational speed will also bring some adverse consequences:
一是过低的转速会减少沼气机的输出功率,降低其动力性;
First, too low rotational speed will reduce the output power of the biogas machine and reduce its power performance;
沼气发电机组
二是过低的转速会导致各部件工作转速下降,将恶化部件的工作性能,降低机油泵的输出压力等;
Second, too low rotational speed will cause the working speed of each component to drop, which will deteriorate the working performance of the component and reduce the output pressure of the oil pump;
三是降低了沼气机的储备功率,使本来应处于正常工作的沼气机处于满负荷或超负荷工作状态;
Third, the reserve power of the biogas machine is reduced, so that the biogas machine that should be in normal operation is in full load or overload working state;
四是转速过低使联动机构工作机械的转速也降低,就会降低工作的机械性能,如降低水泵的出水量,减少水泵的扬程等。
Fourth, if the rotation speed is too low, the rotation speed of the working machinery of the linkage mechanism will also be reduced, which will reduce the mechanical performance of the work, such as reducing the water output of the water pump and reducing the lift of the water pump.
正常发电机组的转速只有两种:一种为1500转/分钟,一种为1800转/分钟,如果人为的把发电机的转速调低或调高,都是错误的行为,请用户在使用时严格按照操作手册执行,不得人为调整发电机组的各项参数。关注我们http://www.huannengpower.com,了解更多!
There are only two speeds of normal generator set: one is 1500 rpm and the other is 1800 rpm. It is wrong to manually lower or increase the speed of the generator. Please strictly follow the operation manual when using the generator set and do not manually adjust the parameters of the generator set. Follow us http://www.huannengpower.com Yes, learn more!
