Description
Technical field
The utility model relates to oil drilling field slurry pump used, especially oil field drill radial plunger slurry pump.
Background technique
In oil drilling field, oil-well rig is equipped with slurry pump.And existing slurry pump is large because reasons in structure exists volume, Heavy Weight, discharges mud pressure and to pulse large problem, affect drilling efficiency.
Summary of the invention
Large in order to solve existing slurry pump volume, Heavy Weight, discharge mud pressure and to pulse large problem, the utility model provides a kind of oil field drill radial plunger slurry pump.It is little, lightweight that this oil field drill radial plunger slurry pump has volume, discharges mud pressure and to pulse little feature.
The technical solution of the utility model is: this oil field drill radial plunger slurry pump comprises the pump housing, radial plunger, cam and sliding footwear.Cam is radial protrusion, cam is connected to vertical shaft upper end, cam level is placed in pump housing upper end hole, drive unit is connected with under vertical shaft, more than 8 radial plungers are arranged in the pump housing along vertical shaft radial direction, sliding footwear are hingedly connected at radial plunger the inner, sliding footwear and cam outer diameter face Structure deformation, the mud feed pathway and mud liquid outlet channel that are connected with plunger cavity is provided with in the pump housing, be respectively arranged with one-way valve in feed pathway and liquid outlet channel, feed pathway and liquid outlet channel are connected with mud exhaust port manifold with mud inlet manifold respectively.
The drive motor of the drive unit in such scheme is axially placed in outside the pump housing, and driven gear is connected horizontally in the pump housing by vertical shaft, and drive motor axle cogs and to be meshed with driven gear; Drive motor is 2; Cam outer diameter face has annular groove, and sliding footwear have rolling bearing, are placed in annular groove.
The utility model has following beneficial effect: this oil field drill radial plunger slurry pump is radial protrusion owing to adopting cam, cam is connected to vertical shaft upper end, cam level is placed in pump housing upper end hole, drive unit is connected with under vertical shaft, more than 8 radial plungers are arranged in the pump housing along vertical shaft radial direction, sliding footwear are hingedly connected at radial plunger the inner, sliding footwear and cam outer diameter face Structure deformation, the mud feed pathway and mud liquid outlet channel that are connected with plunger cavity is provided with in the pump housing, one-way valve is respectively arranged with in feed pathway and liquid outlet channel, what feed pathway and liquid outlet channel were connected with mud exhaust port manifold with mud inlet manifold respectively optimizes structure, to be distributed radial plunger by circumferential level, cam is utilized to drive radial plunger respectively, thus reduced volume, weight reduction, discharge mud pressure pulsation steadily, be convenient to transport and install, and the Security reliability of operation is improved, and structure is simple.To have volume little, lightweight for this oil field drill radial plunger slurry pump thus, discharges mud pressure and to pulse little feature.
