Non-indentation polished rod clamp is a combination of our company actual production experience for many
years and integration of domestic and foreign advanced technology, on the basis of research and development,
which is fully applicable to oil extraction, mining gas production. This product is caught on the rod, through
the reciprocating up and down movement of pumping unit, to produce oil and gas. The product structure
is simple, with anti-loose function, safe for use and convenient for disassembly, adjust position, and workover
operation. It is with good usability.
It has effectively solved the problem of the polished rod body damage caused by the taper slip jamming dens
pressing into rod body and greatly reduced the accident of seriously hurting the seal element to cause oil
leakage due to the scar on the polished rod surface in the process of reulating stoke parameters or changing
pump setting depth.
Operation Manual for Non-indentation polished rod clamp
1. The nominal diameter of polished rod rated center bore should be the same as that of matching polished rod
clamp.
2. The rated working load for polished rod clamp should be more than or equal to the needed polished rod load.
3. Before using, clean polished rod inner bore and oil stains on polished rod surface to guarantee that the surface
is bright and clean.
4. During installation, polished rod clamp lower end should be tightly close to pumping unit carrier bar to avoid
impacting when started.
5. If the viscosity of crude oil in oil well is too big, polished rod lagging down and occurs impacting phenomenon,
our suggestion is to change bigger working load or use two polished rod clamp in the same type, the same
working load together to increase working load. The two polished rod clamp ends should be closely tight when
installation.
6. Two bolts should be fastened evenly for the two-bolt polished rod clamp.
