发电机组的使用对于各种媒介使用要求

来源:http://www.huannengpower.com   发布于:2019-05-29

发电机组的燃气在运用前,应经过预处置(如过滤、气液别离、稳压等)。温渡过高时,还应采用冷却器冷却,以保证燃气中没有液态成分。针对不同燃气,处置的流程也不同。若气源压力缺乏,发电机组虽能正常启动,但可能达不到标定功率。所以用户在选购机组前,应提供气体成分和压力,以便公司提供适合的产品。下面小编引见燃气发电机组对燃气,在间隔机组燃气进气调压阀前1m内的请求。

Gas of generating units should be pre-disposed before operation (such as filtration, gas-liquid separation, voltage stabilization, etc.). When the temperature is too high, the cooler should be used to cool the gas to ensure that there is no liquid component in the gas. For different gas, the disposal process is also different. If the gas pressure is insufficient, the generator set can start normally, but it may not reach the calibration power. Therefore, before purchasing units, users should provide gas composition and pressure, so that the company can provide suitable products. The following section introduces the request for gas from gas generating units within 1 m before the gas intake pressure regulating valve of spacer units.
