Paraffin
Scraper,
Paraffin Scratcher, paraffin inhibitor or
paraffin cleaner.
Are you searching for paraffin control, or solution
for paraffin and mineral scale.
Then, you got the right place.
The Paraffin Scraper , Paraffin Scratcher or Paraffin Cleaner(we
name it Automatic Oilwell Paraffin Cleaner, AOPC)is a device that could
automatically and continuously eliminate paraffin and mineral
scale in wells, using the rod stroke power, without any
alteration to the existing pump equipment, and without any additional
power, or manual work.
It works
independent of the surrounding temperatures and depths of the pump, and
adapts very well to petroleum of various physical and chemical
characteristics and other natural circumstances for differing territories.
Continuously and dynamically working, the Paraffin Scraper eliminates
paraffin essentially in the whole oil channel and thus secures the pump
with a steady (even decreased) load and an electric current.
Simultaneously, it can eliminate such condensed things such as mineral
scales, salt, dirt, scum and colloid that cannot be removed in any other
way. It has simplified as much as possible the procedure of eliminating
paraffin and has secured the steady output - even increased the output of
oil.
The scraper can work instead of the huge equipment and personnel needed for
hot washings of paraffin; therefore saving energy, reducing charges, and
prolonging the period of inspection of the pump to increase efficiency of
oil exploitation.
With the help of the Paraffin Scraper, petroliferous layers will not be polluted,
and there will be no loss of pressure; oil resources are preserved and the
procedure of scientific production of petroleum is advanced.
The principles of
work of the Paraffin Scraper include walking tongue-shaped springs which
clamp the pump rod, transferring energy from a stroke of the rod to
simultaneously drive the Paraffin Scraper and blades at both edges of the
cutter to scrape off such condensed things from the wall of the oil pipe;
such as the paraffin, colloid, scum and salty dirt. While a stroke of the
rod is finished and the rod is on the way back, the Paraffin Scraper is
stopped by reversing fingers, supporting on walls of the pipe, so that the
rod glides through the walking tongue-shaped springs on the way back, and
the coupling of the rod by itself opens and passes through walking
tongue-shaped springs. In this process all the condensed material on the
rod are scraped and eliminated.
The mechanism
includes top reverse, bottom reverse, and the safety unit. Top reverse
includes a reversing body and an elastic stopping ring, while the bottom
reverse includes a reversing body and a rigid stopping ring. The safety
unit includes the adsorbing cylinder and strong magnetic block.
