This is the control cabin of a cementing or fracturing spread, not a pump: a Siemens PLC center console with analog input-output modules sits inside a 4x2 or 4x4 chassis, networked through a looped-plus-star control architecture and backed by 8-12 Motorola radios over a 50 m working radius. From this cabin the operator watches pressure, rate and density from each pump and mixer, talks to the hand positions, and holds the whole job to one synchronized sequence. The sealed, climate-controlled cabin carries that instrumentation and the intercom team through desert, Gobi and plateau locations without the jolt and dust of an open field office.
The control desk is built around a Siemens PLC with analog input and output modules, the brain that reads pump pressure, displacement and density and drives them back to set point. Analog I/O is kept close to the instruments to preserve signal quality on a noisy wellsite.
Field devices are wired on a looped-plus-star control network, so a break in one segment does not blind the whole cabin - the ring routes traffic the other way while the star drops in individual pump and mixer nodes. That redundancy is why the console stays live through a job.
The intercom rack holds 8 to 12 Motorola handsets covering a 50 m radius, enough to staff the pump truck, blender, fluid supply and wellhead positions on one clear channel. Cabling and handsets are checked as part of the pre-job commission.
The instrument cabin is sealed and insulated with temperature and humidity control, so the PLC and radios hold calibration through summer heat and winter cold instead of drifting with a tent or open-truck environment. Dust and rain seals keep field grit off the contact sets.
Sensors and recorders bolt to damped anti-vibration racks rather than directly to the floor, which removes road and pump vibration from the measurement path. Shielded harnesses isolate the data lines from the spread's electrical noise.
A dedicated, low-noise generator and stabilized distribution panel power the console and radios independently of the truck's drive engine, so control stays up even when the chassis engine cycles. Line conditioning protects the PLC from spikes common on oilfield power.

The instrument vehicle is the control cabin of a cementing or fracturing spread, not a pump: a Siemens PLC center console with analog input-output modules, a looped-plus-star control network and 8-12 Motorola radios over a 50 m working radius ride in a sealed, climate-controlled 4x2 or 4x4 chassis. From this cabin the operator watches pressure, rate and density from each pump and mixer, coordinates the hand positions and holds the whole job to one synchronized sequence, in a cabin sealed against desert dust, Gobi wind and plateau temperature swings.
Oilfield precision logging instruments are extremely sensitive to temperature, vibration and dust. Extreme temperature changes cause electronic component failure, and field vibration leads to instrument damage and data deviation. The constant temperature and anti-vibration design effectively avoids environmental interference and ensures the accuracy of detection data and the service life of precision equipment.
The vehicle adopts heavy-duty off-road chassis and full-climate protection design, adapting to desert high temperature, Gobi wind-sand, high-altitude low temperature, muddy roads and remote complex well sites. It supports stable outdoor operation all year round and meets the mobile operation demands of various harsh oilfield environments.
A dedicated low-noise generator and a stabilized distribution panel power the console and radios independently of the truck's drive engine, so control stays up even when the chassis engine cycles. Shielded wiring and anti-interference circuit design isolate external electromagnetic noise, keeping the PLC signal path stable and the job record accurate on site.
Yes. The configuration is settled against the spread before the order: cabin layout, Siemens PLC and analog I/O module count, radio set (8-12 Motorola handsets), temperature control range, power supply configuration and anti-interference measures are matched to the number of pumps and mixers, the 50 m working radius and the region's climate and electrical-hazard rules, then written into the quotation and the factory test report.

The acidizing spread on this truck is built around a centrifugal charge pump that moves 1000 m3/h at 45 m of head, controlled either at the panel or from a 30 m wired remote.
This truck carries two triplex plunger pumps - 3ZB-265 or 3ZB-300 units - on a Beiben ND2254F50J 6x6 chassis, each rated to put 70 MPa and a combined 100 m3/h into the casing string.
The support role on a cementing or fracturing spread is filled by this truck's centrifugal pump - 750 m3/h at 45 m of head - feeding clean water or fracturing fluid to where the active equipment is working.
