| titleOfInvention | The lower integrated dusting power drug viscosity-falling unit of pump on a kind of viscous crude well pump |
| abstract | The lower integrated dusting power drug viscosity-falling unit of pump, measures and is sequentially connected filter, Pump pressure meter, flowmeter on the outlet backbone of dosing pump left end on a kind of viscous crude well pump；Its backbone tail end designs a threeway, threeway left end connects blow valve, upper end connection pump top set, top set is pumped to be equipped with pump upper flow valve and connect oily nonyl on pumping, the top connection that tail end is equipped with is connected with the resistance oil nozzle sleeve on production tree, threeway lower end connection pump inferior division, pump inferior division are connected equipped with the lower catch hoop head that lower flow-limiting valve and the oily nonyl of the lower connection of pump, tail end are equipped with is pumped with the casing head on production tree；The utility model makes oily well capacity reach best according to relevant natures such as oil well crude oil viscosity, wellhead temperature, crude outputs, using current limliting valve regulation dusting power drug amount size to reduce on oil pump or pump lower viscosity of crude；Have the advantages that structure is simple, connection is quick, safe and reliable simultaneously. |
