瓦斯发电机组厂家告诉你冬季柴油发电机为什么启动困难?

来源:http://www.huannengpower.com   发布于:2019-11-05

  柴油发电机的启动不仅取决于其技术条件,而且还受到外界温度的影响。瓦斯发电机组厂家认为,冬季低温下启动困难,主要有以下原因。

  The start-up of diesel generator depends not only on its technical conditions, but also on the influence of external temperature. According to the manufacturer of gas generator set, it is difficult to start at low temperature in winter, mainly due to the following reasons.

  冬季气候寒冷,环境温度低,机油粘度增大,各运动部件的摩擦阻力增大,使起动速度降低,起动困难。

  In winter, the climate is cold, the environment temperature is low, the viscosity of oil is increased, the friction resistance of all moving parts is increased, the starting speed is reduced and the starting is difficult.

  其次,电池容量随着温度的下降而下降,从而使启动速度进一步降低。

  Secondly, the battery capacity decreases with the decrease of temperature, which further reduces the starting speed.

  3.起始速度降低,压缩空气泄漏增加,和缸壁的散热增加,空气的温度和压力的压缩是大大减少,导致柴油点火延迟时间的增加,在严重的情况下甚至不能燃烧。

  3. The decrease of initial speed, the increase of leakage of compressed air, the increase of heat dissipation of cylinder wall, the decrease of compression of air temperature and pressure greatly lead to the increase of ignition delay time of diesel, even unable to burn in serious cases.

  4.柴油低温粘度的增加将减少注射速度,和低涡流速度、温度和压力的压缩将导致雾化质量差的柴油喷入发动机气缸,难以形成良好的可燃气体与空气迅速和及时的点火和燃烧,甚至不能着火,导致困难的开始。

  4. The increase of low temperature viscosity of diesel will reduce the injection speed, and the compression of low vortex velocity, temperature and pressure will lead to the injection of diesel with poor atomization quality into the engine cylinder, which is difficult to form a good combustible gas and air to ignite and burn quickly and timely, or even fail to ignite, leading to the difficult start.
