8. On-Site Fault Maintenance Cases

The following are 4 real on-site fault maintenance cases of 3ZB-600 pump spare parts, which are common faults in actual oilfield drilling and mining operations. Through these cases, users can quickly judge and solve similar faults, reduce pump downtime, and provide practical reference for technical maintenance. All cases use our genuine spare parts for maintenance, ensuring the effect and stability:

Case 1: 3ZB-600 Pump Hydraulic End Leakage Fault

• Fault Phenomenon: During the drilling fluid circulation operation of the 3ZB-600 pump, there is obvious medium leakage at the plunger of the hydraulic end, resulting in reduced pump discharge pressure and pumping efficiency, and the surrounding components are corroded by the drilling fluid.

• Fault Judgment: After on-site inspection, it is found that the leak-free packing seal assembly (G04050500004AA) of the plunger is worn and aged (the packing has been used for more than 800 working hours), and the packing fibers are broken, resulting in poor sealing performance; at the same time, there are sand particles on the plunger surface, which aggravate the wear of the packing.

• Maintenance Method: Stop the pump operation immediately, drain the drilling fluid in the hydraulic end; disassemble the gland (P1300127AA), remove the worn leak-free packing seal assembly; clean the plunger surface with professional cleaning agent to remove sand particles and stains; replace it with the original genuine leak-free packing seal assembly (G04050500004AA), adjust the gland tightness (not too tight to avoid increasing friction), and reinstall the gland; start the pump for test run, the leakage fault is solved, the discharge pressure is restored to the rated value, and the pumping efficiency is normal.

• Preventive Measures: Regularly check the packing seal assembly during daily maintenance; replace the packing in time when it is found to be aging or worn; keep the drilling fluid clean to avoid sand particles entering the hydraulic end and damaging the packing and plunger.

Case 2: 3ZB-600 Pump Pressure Instability Fault

• Fault Phenomenon: During the operation of the 3ZB-600 pump, the discharge pressure fluctuates greatly (10-50MPa), the pressure gauge shows unstable, and there is abnormal noise at the pressure relief valve, which affects the normal operation of the drilling fluid circulation system.

• Fault Judgment: On-site inspection shows that the pressure relief valve (G09050000002AA) is clogged by impurities in the drilling fluid, resulting in inaccurate pressure regulation; the valve core of the pressure relief valve is worn, and the sealing surface is not tight, leading to frequent opening and closing of the valve; in addition, the filter element of the medium filter is clogged, which affects the medium quality and causes the pressure relief valve to fail.

• Maintenance Method: Stop the pump operation, cut off the medium source; disassemble the pressure relief valve (G09050000002AA), clean the valve core and valve seat with cleaning agent to remove impurities, and grind the worn sealing surface to restore the tightness; replace the clogged filter element; reinstall the pressure relief valve, adjust the relief pressure to the rated value (60MPa); start the pump for test run, the pressure is stable, and the abnormal noise disappears.

• Preventive Measures: Regularly clean the pressure relief valve and filter element; keep the medium clean; check the pressure relief valve regularly for wear and pressure regulation accuracy, and replace it in time if necessary.

Case 3: 3ZB-600 Pump Power End Abnormal Noise Fault

• Fault Phenomenon: During the operation of the 3ZB-600 pump, there is harsh abnormal noise in the power end, and the noise increases with the increase of the pump speed; the temperature of the power end bearing is too high (exceeding 70℃), which affects the normal operation of the pump.

• Fault Judgment: After on-site inspection, it is found that the bearing (matching YL600-70 3ZB-600) of the power end pinion shaft is worn and damaged, the bearing inner ring is loose, and the lubricating oil of the power end is deteriorated, resulting in insufficient lubrication and increased friction between the bearing components; the gear surface is also worn due to insufficient lubrication, leading to abnormal noise.

• Maintenance Method: Stop the pump operation, disassemble the power end box; remove the worn bearing and the deteriorated lubricating oil; clean the power end inner cavity, gears, and shafts; replace it with the original genuine bearing (matching YL600-70 3ZB-600), add new lubricating oil that meets the standards; check the gear wear, and grind the gear surface if there is slight wear; reassemble the power end box, start the pump for test run, the abnormal noise disappears, and the bearing temperature is stable within the normal range (40-60℃).

• Preventive Measures: Regularly check the power end bearing temperature and lubricating oil quality; replace the lubricating oil and bearing regularly according to the maintenance cycle; ensure sufficient lubrication of the power end components.

Case 4: 3ZB-600 Pump Valve Blockage Fault

• Fault Phenomenon: The 3ZB-600 pump has no discharge pressure during operation, the medium cannot be discharged normally, and the pump body vibrates obviously; the suction pressure is normal, but the discharge pipeline has no medium flow.

• Fault Judgment: After on-site inspection, it is found that the discharge valve (valve body cover K3105003AA) is blocked by large particles of impurities in the drilling fluid, the valve core cannot open normally, resulting in the medium cannot be discharged; the discharge valve spring (P9000131AA) is also deformed, which affects the closing of the valve core.

• Maintenance Method: Stop the pump operation, drain the drilling fluid in the hydraulic end; disassemble the discharge valve cover (K3105003AA), remove the blocked valve core and deformed valve spring; clean the valve body and valve core with cleaning agent to remove impurities; replace the deformed valve spring with the original genuine one (P9000131AA), reinstall the valve core and valve cover, and tighten the bolts; start the pump for test run, the discharge pressure is restored to normal, and the medium is discharged smoothly.

• Preventive Measures: Regularly clean the discharge valve and suction valve during daily maintenance; replace the filter element of the medium filter regularly to prevent large particles of impurities from entering the hydraulic end; keep the drilling fluid clean.
