CEMENTING AND FRACTURING UNITS
The cementing and fracturing
units are designed to perform both
cementing and hydraulic fracturing
operations, as well as other pumping
operations required for well
maintenance
The
cementing units can be delivered for
maximum working pressures 350, 400, 500,
700 or 1050 bar . For
350 bar working pressure cementing units
the pump can be equipped with plungers
or pistons and is driven using chasis
engine power take off. Cementing
units 400, 500, 700 and 1050 bar working
pressure can be equipped with one or two
plungers cementing pumps, each driven
form a diesel engine. Driving
of cementing pump from diesel engine is
assured through a hydraulical
transmission or a mechanical gear box For
both constructions engine and
transmission controls are located on
unit control panel The
cementing units can be offered in two
alternatives. -
Equipped
with low stroke per minute (low input
sfaft rpm speed) cementing pump which de
not requires overcharging during
functioning. -
Equipped
with high stroke per minute (high input
sfaft rpm speed) cementing pump, which
requires overcharging during
functioning. The
main technical characteristics data of
cementing units for 400 to 1050 bar
working pressures are shown in the
following table:
