Cementing Units | ACF 700 DS Cementing and Fracturing Unit
Destination: ACF 700 DS cementing units are mobile units designed to perform cementing operations as well as other operations at the wells, at low temperatures (-40°C ÷ +40°C).
The cementing units are mounted on URAL 4320 chassis trucks.
The cementing units are equipped with a high pressure triplex plunger pump that provides the technical parameters at normal suction.
The Cementing and Fracturing Units are designed to perform the interchangeability of pieces and subassy.
The pumps are designed to run on reduced revolutions providing proper filling of pump cylinders and more than 0,9 volumetric efficiency on natural suction without supercharging.
The power required to drive the triplex pump is supplied by the Detroit Diesel DDC model power group, DDC serie 60, by means of a CV 12-352 Gear box.
The gearbox is driven by a motor with cardan shaft driving the plunger pump by toothed coupling and the water pump by elastic coupling.
The cementing units are equipped with a measuring tank, divided into two equal compartments, protected against the corrosion.
For cementing operations, the cementing units are equipped with jet mixer with 3 nozzles supplied with water by a water pump. Water supply to the mixer is so conceived to provide parallel operation of one, two or all three nozzles of the mixer, as required, providing 100 to. blend/hour.
The controls of the unit are centralized and may be actuated from the platform located around the control panel.
On the control panel are mounted instruments for checking the operation of the plunger pump and water pump, as well as instruments required to check the operation of the driving motor.
For checking the discharge pressure, the cementing units are equipped with pressure gauges with environment insulator and vibration dampener, mounted on the discharge collector of the pump.
The manifolds of unit provide the following functions:
- Triplex plunger pump suction from each compartment of the measuring tank, from the slurry sump or from other external source, on both sides of the unit.
- Triplex pump discharge towards the pumping line through the 2" x 700 bar valve. Discharge on free line through the 2" x 700 valve and ajustable nozzle. The adjustable nozzle permits slow reduction of the pressure on free flow line.
- Supply of measuring tank, independent for each compartment from external source.
- Water pump suction from each compartment of the measuring tank and water pump discharge towards the mixer cement.
To protect the entire hydraulic system against overpressure, the discharge manifold is provided with safety valve and water pump manifold is provided with spring valve.
