Technical field
The utility model relates to a kind of oil and gas multiphase flow equipment, particularly the mixed conveying device of a kind of screw pump.
Background technique
The character of screw pump fed sheet of a media, all more complicated of state may result in blockage in pipeline.Because helical rotor pump is the pump of positive displacement type, in the time there is obstruction or human operational error, can cause the superpressure of pump, be easy to damage its component, mixing pump outlet easily causes medium to flow backwards and mixing pump reversion, causes the damage of screw pump, reduces working efficiency.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of screw pump to mix conveying device.
Its technological scheme is: comprise separator, natural gas line, oil-gas pipeline, blowdown pipeline, the first oil-gas mixed delivery pump, the second oil-gas mixed delivery pump, pressure transmitter, frequency-conversion control cabinet, pressure relay, one-way valve, oil and gas multiphase flow pipeline, separator connects respectively natural gas line and oil-gas pipeline, the bottom of separator connects blowdown pipeline, described separator outlet connects the first oil-gas mixed delivery pump and the second oil-gas mixed delivery pump, the first described oil-gas mixed delivery pump is connected oil and gas multiphase flow pipeline with after the second oil and gas multiphase flow parallel connection of pumps, the first described oil-gas mixed delivery pump and the import of the second oil-gas mixed delivery pump are provided with pressure transmitter, the first oil-gas mixed delivery pump and the second oil and gas multiphase flow delivery side of pump are provided with pressure relay, described pressure transmitter is connected frequency-conversion control cabinet with pressure relay, the first oil-gas mixed delivery pump and the second oil and gas multiphase flow delivery side of pump are provided with one-way valve.
Above-mentioned frequency-conversion control cabinet connects alarm.
The beneficial effects of the utility model are: pressure relay signal is delivered to frequency-conversion control cabinet and realized over pressure automatic alarm, pump trip, guarantee the normal work of gas mixing pump; The one-way valve of oil and gas multiphase flow pump discharge plays and prevents that medium from flowing backwards and the effect of mixing pump reversion.
