In order to remove the gasification phenomenon in said circumstances, gas station manager can send special messenger to safeguard.When doubtful gasification occurs, the air vent that miantainers just open turbine pump is exhausted, and gas retells air vent and closes after all discharging.Thus, turbine pump just can run well.Although can removing gasification phenomenon by artificial mode, in this process, there is following several defect.
1. turbine pump air vent UNICOM be the inner and ambient atmosphere environment of turbine pump, therefore gaseous petroleum gas is finally discharged in external environment.And LPG is more or less containing harmful matter, not only befouling environment also can cause physiological damage to miantainers.
2., because LPG belongs to inflammable and explosive substances, therefore in exhaust process, there is huge potential safety hazard.Once have an accident, consequence is hardly imaginable.
3., owing to taking the mode of artificial exhaust, therefore necessarily increase human cost.
4. gaseous petroleum gas is directly discharged to the external world, result also in waste of fuel, if things go on like this, must reduce profit of operation.
In sum, not only there is huge potential safety hazard but also can not fundamentally eliminate gasification phenomenon in the mode of artificial venting, and is unfavorable for promoting the use of on a large scale.
