冬季来临,气动增压泵容易出那些问题?

冬季来临,气温下降,气动增压泵容易出现什么问题?今天给大家讲一讲
When winter comes and the temperature drops, what problems are prone to occur with the pneumatic booster pump? Let me tell you today
驱动气动增压泵工作的压缩空气做功之后,是要排放到大气里的,气压由0.3-0.8MPa,瞬间降至大气压力,压缩空气释放的过程是个吸热的过程,
After the compressed air driving the pneumatic booster pump works, it is discharged into the atmosphere. The air pressure decreases from 0.3-0.8mpa to atmospheric pressure instantly. The release process of compressed air is an endothermic process,
当压缩空气含水份较大时,夏季你会发现排气口会凝结很多小水珠,排气口的温度也会比较低,到了冬季,就不会以水珠的形态出现了,开始结霜,慢慢的结冰,换向阀芯动作卡滞,进而泵停止工作,所以要冬季,气动增压泵要尽量在温度较高的环境内使用,且降低压缩空气的露点,如加冷干机,些时加配一支油雾器,保证换向阀的换向灵活顺畅。
When the water content of compressed air is large, you will find that many small water droplets will condense at the exhaust port in summer, and the temperature at the exhaust port will be relatively low. In winter, it will not appear in the form of water droplets. It starts to frost, slowly freezes, the action of reversing valve core is stuck, and then the pump stops working. Therefore, in winter, the pneumatic booster pump should be used in the environment with high temperature as much as possible, And reduce the dew point of compressed air. For example, add an oil mist when adding a cold dryer to ensure the flexible and smooth reversing of the reversing valve.
还是对使用介质为水的气液增压泵,冬季使用完毕后,要切断水源,让泵空动作1-2分钟,让泵内液体排出,如内腔结冰或单向阀冰,同样无法使用。
For the gas-liquid booster pump with water as the medium, after use in winter, cut off the water source and let the pump empty for 1-2 minutes to discharge the liquid in the pump. If the inner cavity freezes or the one-way valve freezes, it can not be used.
