Display needs to discharge the location information of the liquid reserve tank of liquid, and is alarmed by alarm, and staff is reminded to dismantle
Liquid is accumulated in release, realizes periodic inspection function；
Step S4, pressure in pressure sensor real-time detection surge tank are simultaneously sent to controller and are compared with preset pressure numerical value
Compared with when the interior pressure of surge tank is greater than preset pressure numberical range, pressure signal is sent to controller by pressure sensor, control
Device processed controls solenoid valve, oil well pump, aspiration pump and simultaneously closes off, and oil-gas mixed delivery pump continues to siphon away the oil gas in surge tank, until
Pressure in surge tank is in preset pressure numberical range, and controller controls solenoid valve and opens, and oil well pump, aspiration pump are opened again
Beginning work, when the pressure in the surge tank of pressure sensor detection is less than preset pressure numberical range, controller controls oil gas
Mixing pump is closed.
Described sleeve pipe gas collection device is casing gas collection device of any of claims 1-9.
