• ‌Output Water Power‌: 2500 horsepower (some models achieve actual installed power up to 3200 horsepower) ‌
• ‌Working Pressure‌: Up to 120MPa (tested at 125MPa at wellhead) ‌
• Displacement: Varies by plunger diameter (e.g., parameters not specified for 4-1/2″ plunger diameter)
• Chassis Load Capacity: 45 tons (design weight 47 tons; load-bearing structures require reinforcement in actual use due to road conditions)

 

 

Low Pulsation: The five-plunger design ensures a flow pulsation rate of $\le 6\%$, significantly reducing vibration and noise.

Long Service Life: The combination of ceramic plungers and alloy cylinder liners extends the service life by up to 3 times.

Powerful Self-Priming: Featuring an enlarged water inlet diameter and optimized flow channels, the suction lift reaches up to 8 meters.

Corrosion Resistance: The nickel-plated brass pump head is designed to withstand corrosive media such as weak acids, bases, and seawater.

 

 

Oil Well Fracturing for Enhanced Production: Injecting fracturing fluids to create fractures and increase output.

Acidizing and Plugging Removal: Pumping acidic solutions to clear blockages and restore flow.

Proppant Transport: Transporting sand-bearing fluids to fill fractures and maintain flow channels.

Water Injection for Oil Displacement: Injecting water to displace crude oil and improve recovery rates.

Wellbore Cleaning: Using high-pressure liquids to clean the wellbore walls and restore cleanliness.

Fracturing Fluid Preparation: Transporting base fluids and additives to prepare fracturing fluids.

 

 

1. Lubrication System Failures
If the oil temperature alarm triggers, check the radiator fan speed (800-900 rpm), verify the radiator is clear, and ensure the thermostat is functioning. Maintain the oil tank level between 2/3 and 4/5 capacity.

 

2. Mechanical Component Wear
Change oil and clean the filter after 500 hours. Inspect wear-prone components like rod bolts and seals at 1000 hours. Conduct full maintenance every 5000 hours, including bearing clearance and seal checks.

 

3. Hydraulic System Abnormalities
Clean or replace clogged filters to prevent pressure fluctuations. Repair or replace valve seals and adjust piston-cylinder clearance as needed.

 

4. Cooling System Maintenance
Regularly clean radiator surfaces. During shutdown, check coolers for leaks and ensure proper coolant flow.

 

 

After ruling out false alarms and low oil levels, systematically check the following:

 

1. Radiator Fan Not Operating or Insufficient Speed
Check: Verify the fan is running at 800-900 rpm.
Solution: Increase engine speed to 1900 rpm, close the fan cooling switch, and use a tachometer to confirm the fan speed.

 

2. Clogged Radiator Core Surface
Check: Inspect the radiator for blockages (sludge, leaves, debris).
Solution: Clean the radiator core as needed. For detailed instructions, refer to "【Knowledge Boost】How Much Do You Know About Fracturing Equipment - Cooling System."

 

3. Thermostat Malfunction
Check: If oil temperature rises significantly after operation, inspect the thermostat circuit.
Solution: Measure the temperature at the C-port and A-port; if C-port is lower than A-port, the thermostat hasn't opened. Disassemble, inspect, and replace the thermostat if needed.
