During vacuum pump work, spill port, under the effect of oil gas, is closed by the sealing member in gas and oil separating plant, and locating part is positioned at spill port, limits sealing member position in spill port.
In the vacuum pump that above-mentioned a kind of safety is good, described stopping means includes a spacer pin being arranged in described spill port.
Compared with prior art, this utility model has the advantage that
1, this vacuum pump adopts electronic centrifugal switch replace traditional mechanical type centrifugal switch, make to produce without arc spark during electric motor starting, be also devised with no-spark on and off switch, it is possible to decrease the generation of potential safety hazard, improve the safety of this vacuum pump;
2, the oil gas passed through is easily separated by the filter element in the gas and oil separating plant in this vacuum pump, fuel tank is back flowed back into by the spill port on the fixing seat of this segregation apparatus after oil is separated, achieve the recycling of Oil-gas Separation and oil, decrease the wasting of resources, reduce to the number of times of vacuum pump fuel feeding, save cost and improve work efficiency.
