JLMECH：Your Trusted Parts of Diesel Generator Manufacturer & Supplier

At JLMECH, we understand that the reliability of a diesel generator hinges on the quality and precision of its individual components. As a leading global manufacturer and supplier of high-quality diesel generator parts, we provide critical basic components to ensure that power generation systems worldwide achieve optimal performance, extended service life, and operational safety.

Parts of Diesel Generator Description

A diesel generator is a complex integration of mechanical and electrical systems. Understanding its core components is crucial for efficient operation, maintenance, and procurement. Below is a breakdown of parts of diesel generator:

Engine Block and Core Assembly (Power Source)

• Engine Block/Cylinder Block: The foundational structure housing cylinders, coolant passages, and main bearings. JLMECH blocks are cast from high-grade iron/steel for maximum durability.
• Cylinder Head and Liners: Precision-machined heads seal combustion chambers, while replaceable liners ensure cylinder integrity under extreme pressure and heat.
• Pistons, Connecting Rods, and Crankshaft: Convert linear motion into rotational force. Our forged steel crankshafts, high-strength alloy pistons, and hardened connecting rods withstand immense stresses.
• Fuel Injection System: Uses precision components like injectors, fuel pumps (injection pumps), and high-pressure lines to achieve efficient combustion.
• Turbocharger and Aftercooler: Boosts air intake density to increase power output efficiency. JLMECH provides matched turbo systems and efficient aftercoolers.
• Cooling System: Water pumps, radiators, thermostats, and hoses manage critical engine temperatures.
• Lubrication System: Oil pumps, filters, and coolers ensure continuous clean oil flow to bearings and moving parts.

Generating System (AC Power Conversion)

• Stator: The stationary component with windings for inducing alternating current (AC). JLMECH stators feature high-quality copper windings and robust insulation (Class H standard).
• Rotor (Field Rotor): A rotating electromagnet powered by DC excitation current to create a magnetic field. Precision-balanced for smooth operation.
• Automatic Voltage Regulator (AVR): A key control unit maintaining stable output voltage under varying loads and conditions. JLMECH offers advanced AVRs compatible with major brands.
• Excitation System: Supplies DC current to rotor windings (available in brushless or static excitation systems).
• Bearings: High-capacity bearings reliably support the rotor shaft.

Control and Monitoring System (The Intelligent Brain)

• Control Panel: Houses gauges, switches, controllers, and communication interfaces, ranging from basic manual starters to complex digital touchscreens.
• Controller (Generator Control Unit - GCU): The central processor managing start/stop sequences, engine parameters (RPM, temperature, oil pressure), generator output (voltage, frequency, current), protection functions, and remote monitoring (optional). JLMECH provides controllers from brands like DSE, ComAp, and Deep Sea.
• Sensors and Transducers: Continuously monitor key parameters (speed, temperature, pressure, voltage, current) and transmit data to the controller.
• Circuit Breakers and Protection Relays: Safeguard the generator and connected loads against electrical faults (overload, short circuit, voltage/frequency anomalies).

Auxiliary Components and Safety Systems (Ensuring Operation and Protection)

• Starting System: Starter motor, starter solenoid, and batteries for engine cranking.
• Air Intake and Exhaust System: Air filters, intake manifolds, exhaust manifolds, mufflers/silencers, and flexible exhaust bellows to manage air flow and emissions.
• Fuel System: Fuel tanks (base or external), filters (primary/secondary), fuel lines, and water separators to ensure clean fuel delivery.
• Mounting System: Base frames (steel skids) and anti-vibration mounts for structural support and vibration isolation.
• Safety Devices: Critical shutdown sensors (low oil pressure, high coolant temperature, overspeed) and emergency stop buttons to prevent catastrophic damage.

Other Add-On Components (Enhancing Functionality)

• Battery Charger: Maintains starter battery health.
• Heaters: Block heaters (engine coolant) and crankcase heaters for easier cold starts.
• Transfer Switches (ATS/MTS): Automatically or manually switch loads between utility and generator power.
• Sound Attenuation Enclosures/Canopies: Significantly reduce operational noise.
• Remote Monitoring Kits: Enable remote status checks and control via network/internet.
