Power System: Electric motor (converts electrical energy into mechanical energy)
Transmission System: Crankshaft, connecting rod (converts rotary motion into reciprocating motion)
Compression System: Piston, cylinder (completes gas compression)
Auxiliary Systems: Lubrication system, cooling system, control system
Startup Stage: The electric motor starts, converting electrical energy into kinetic energy
Energy Transmission: The electric motor drives the crankshaft to rotate
Motion Conversion: The crankshaft transmits rotational kinetic energy to the connecting rod
Reciprocating Motion: Driven by the connecting rod, the piston performs reciprocating motion
Cycle Completion: Each rotation of the crankshaft completes one reciprocating motion of the piston
During this complete process, the compressor cylinder sequentially completes three key stages: suction, compression, and discharge, forming a full working cycle. The continuous reciprocating motion enables efficient pressurization and transportation of natural gas.
Data Recording: Promptly check and record various operating parameters after startup, including pressure, temperature, current, vibration and other key indicators, and establish an equipment operation file
Leak Inspection: Thoroughly check all compressor connections for gas, oil, or water leakage, and promptly detect and resolve seal failures
Instrument Verification: Confirm that all instruments (pressure gauges, temperature gauges, oil pressure gauges, etc.) function properly and readings are within normal ranges
Liquid Level Inspection: Check the engine oil level in the crankcase to ensure sufficient oil supply for the lubrication system
Fastening Inspection: Check anchor bolts, pipeline joints and other connections for looseness or detachment to prevent connection failure caused by vibration
Safety Accessory Inspection: Check that all safety accessories (safety valves, pressure switches, temperature switches, etc.) operate normally to ensure sensitive and reliable protection devices
Valve Maintenance: Inspect and clean intake and exhaust valves, remove carbon deposits and contaminants from valve plates and seats, and replace damaged valve plates, springs and other parts
Fastener Inspection: Focus on checking the tightness of crosshead pins and piston-connecting rod locking screws to ensure reliable connection of moving parts
Separator Maintenance: Inspect and clean separator filter elements, verify that the blowdown device is unobstructed, and prevent impurities from entering downstream systems
Comprehensive Bolt Inspection: Check the reliability of all bolts and connecting devices, including not only anchor bolts but also cylinder head bolts, bearing cap bolts and other key fasteners
Breather Cleaning: Clean the crankcase breather to ensure pressure balance in the crankcase and prevent oil and gas leakage
Lubrication System Maintenance:
Replace engine oil and remove impurities and wear products from used oil
Clean the oil filter element to ensure filtering efficiency
Check that the clearance between the main bearing and crankshaft meets standards
Verify normal clearance between the small end bearing and crosshead
Safety Accessory Calibration: Check the sensitivity of all safety accessories and perform regular calibration as required to ensure reliable operation under overpressure and other abnormal conditions
Cylinder Adjustment: Inspect and adjust the piston end clearance of the compression cylinder to maintain the designed compression ratio and clearance volume
Alignment Inspection: Inspect and adjust the alignment of the coupling to prevent increased vibration and premature component wear caused by poor alignment
Carbon Deposit Removal: Thoroughly remove carbon deposits from the compression cylinder, piston rings, and intake/exhaust valves, measure relevant clearances, and restore normal component performance
Moving Parts Inspection: Check the wear of crossheads, crosshead pins and bearings to assess replacement needs
Lubrication Replenishment: Replenish grease to motor bearings, oil pumps and other parts requiring regular lubrication
Comprehensive Lubrication System Overhaul:
Clean and inspect the entire lubrication device and system
Check valves, oil pumps and other components, replace or repair damaged parts
Ensure unobstructed oil circuits and uniform oil supply
Fastening Status Review: Comprehensively inspect the fastening status of all bolts and connections, and retorque key bolts to specified values
In-Depth Compression Component Inspection:
Check the wear condition of the compression cylinder
Inspect the elasticity and wear of piston rings, replace if necessary
Check intake and exhaust valve springs, replace failed or fatigued springs
Cooling System Maintenance:
Remove contaminants from inside and outside radiators and coolers
Inspect for leaks or blockages
Ensure cooling performance meets requirements
Piston Rod Inspection:
Check surface wear of the piston rod
Assess whether repair or replacement is needed
Inspect the piston rod packing seal, replace worn packing
Major Component Wear Assessment:
Check crosshead clearance and small end bearing clearance
Comprehensively evaluate wear of crankshaft, main bearing, small end bearing, connecting rod, piston-connecting rod, cylinder, valves and other major components
Determine replacement plans and maintenance schemes based on wear severity
Ensure Operational Stability: Significantly reduce the probability of sudden failures through preventive maintenance, guaranteeing continuous and stable operation of natural gas compression equipment
Improve Operational Safety: Timely detect and eliminate potential hazards, effectively avoiding safety accidents caused by equipment failures
Extend Equipment Life: Scientific maintenance slows component wear, prevents structural damage, and significantly extends the overall service life of the compressor
Optimize Operating Efficiency: Keep equipment operating at optimal conditions to achieve higher energy efficiency and gas transmission capacity
