Automatic filling system for gas well defoamer

The invention discloses an automatic filling system for a gas well defoamer, which comprises a differential pressure sensor, a processor and an injection pump, wherein the differential pressure sensor is used for detecting liquid flow pressure in a gas production pipeline and transmitting the detected pressure signal to the processor; the processor has a preset liquid flow pressure trigger value, and the received liquid flow pressure value is compared with the trigger value, wherein if the real-time value is higher than the trigger value, the processor conducts the power supply of the injection pump to inject the defoamer, and if the real-time value is lower than the trigger value, the processor disconnects the power supply of the injection pump to stop the injection pump; and thus the injection pump is controlled by the processor to start or stop the addition of the defoamer. The automatic filling system for the gas well defoamer is capable of filling the defoamer according to the liquid production condition of a gas well in real time, thereby ensuring that the defoamer can play a role in time when liquid is produced; and when no liquid is produced, the addition of the defoamer can be quickly stopped, thereby avoiding untimely and unreasonable conditions caused by artificially starting pump injection, saving a large amount of the defoamer and improving the defoaming effect.
