Abstract
The utility model discloses a scale prevention oil extracting pump, which comprises a pump cylinder, a piston, a fixed valve, a downstream movable valve, an upstream movable valve and a fixed valve protection cover. The scale prevention oil extracting pump is characterized in that the fixed valve protection cover is arranged at the bottom of the fixed valve of the oil extracting pump, a movable valve protection cover is arranged at the top of the upstream movable valve of the oil extracting pump, and a slotted screen pipe is arranged at the bottom of the fixed valve protection cover. The scale prevention oil extracting pump is simple in structure, quick and convenient to operate, quick in construction and capable of greatly shortening construction periods and increases work efficiency.
Description
Technical field
The utility model belongs to technical field of petroleum extraction, particularly a kind of antiscale oil extraction pump.
Background technique
Oil extraction pump causes valve leakage or malfunctioning often by solid particle in injected water at present, thereby makes whole oil extraction pump leakage or malfunctioning occur, brings very large economy loss for our industrial production.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of antiscale oil extraction pump at above the deficiencies in the prior art.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of antiscale oil extraction pump; comprise pump barrel, piston, standing valve, following travelling valve, go up travelling valve, standing valve safety cover; wherein; bottom at the standing valve of oil pump is provided with the standing valve safety cover; the top of travelling valve is provided with moving valve safety cover on oil extraction pump; bottom at the standing valve safety cover is provided with cutting seam sieve tube, and the cutting seam sieve tube bottom is connected with plug.
Described standing valve safety cover is the hemisphere reticular structure, and the travelling valve safety cover is the taper reticular structure.
The utility model is simple in structure, and long service life can effectively prevent solid particle in injected water standing valve and travelling valve, reduces oil extraction pump and leakage or malfunctioning probability occur.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
