  What is the engine crankshaft ? The crankshaft is an important part of the engine. Supports the force from the connecting rod, which is converted into torque. Torque is output from the crankshaft and activates other components of the engine. The crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodically changing gas inertial force, and the reciprocating inertial force, and as a result, the crankshaft is subjected to bending and torsional loads. Therefore, the crankshaft must have sufficient strength and stiffness, and the crankshaft surface must be wear-resistant, work evenly, and be balanced. In order to reduce the mass of the crankshaft and the centrifugal force generated in the motion, the crankshaft journals are often hollow. The surface of each journal has oil holes that allow oil to be introduced or drawn out to lubricate the surface of the journal. To reduce stress concentrations, the connection between the main column, c...

 Diesel generators generate a lot of heat during operation, and internal components need to be cooled frequently in order not to damage the generator. Most diesel generators are air-cooled or liquid-cooled. The cooling method is a fundamental design element of the generator and is usually determined by the power and type of the generator. Air cooling systems are often used for small generators, but larger generators require a liquid cooling system. Today, we will explain the advantages and disadvantages of air-cooled and liquid-cooled diesel generator systems for reference when purchasing diesel generators. Air-cooled diesel systems utilize air circulation to cool the unit. In an air-cooled system, the diesel engine sucks in cold air from the atmosphere and then blows cold air from the generator set to prevent the generator from overheating. Air-cooled diesel engines are typically used for portable diesel generators and backup diesel generators up to 22kw. There are two option...

 An alternator is a generator that converts mechanical energy into electrical energy in the form of alternating current. For reasons of cost and simplicity, most motors use the rotating magnetic field of a stationary motor. Induction cooktops and rotating armatures with fixed magnetic fields are also sometimes used. In principle, any electric motor can be called an electric motor, but the term usually refers to a car or other small rotating machinery powered by an internal combustion engine. Magnetic devices that use permanent magnets to generate a magnetic field are called magnetrons. Turbines in power plants powered by steam turbines are called turbo turbines. Large 50 or 60hz three-phase motors in power plants generate most of the world's electricity and are distributed by the grid. Maintenance of the alternator should pay attention to the problem The charging (power supply) system consisting of the electric alternator is one of the two power supply groups in the car, and its ...

An Introduction to Starter Motor The starter motor has the characteristics of wide application, simple structure, convenient operation, easy maintenance, and low cost. It is currently widely used in marine medium-speed diesel engines. The ring gear drives the diesel engine to rotate. Of course, this starting device also includes a pressure-reducing valve, a starting solenoid valve, and other equipment. When the starter solenoid valve is opened, the 3MPa high-pressure air supplied from the outside will pass through the self-configured pressure reducing valve to reduce the air pressure to about 1MPa. , meshes with the flywheel ring gear. When fully meshed, the high-pressure air of the main circuit begins to enter the inside of the starter motor, drives the internal piston, and drives the internal turbine impeller through the piston to drive the pinion to rotate, and the pinion drives the meshing flywheel ring gear. , The flywheel ring gear drives the flywheel, the flywheel drives the cr...

 The Introduction and Function of Landkingparts' Good Fuel Injector Does everyone know about fuel injectors ? Today, I will introduce the role of fuel injectors. A fuel injector is a precision device with extremely high machining accuracy that requires a large dynamic flow range, strong anti-clogging and anti-pollution features, and atomization. Next, allow me to describe the function of the fuel injector. The electronically controlled injector is the most important and complex component in a common rail system, and it is also the most difficult to design and handle. The ECU controls the switch of the solenoid valve to inject the fuel in the high-pressure rail into the combustion chamber with the optimum injection timing, injection quantity, and injection rate. In order to achieve an effective fuel injection starting point and precise fuel injection quantity, the common rail system adopts a dedicated fuel injection device, equipped with a hydraulic servo system and electronic contr...

 The bushing is the cylindrical mechanical part of the independent plain bearing that supports the shaft. Bearings are primarily constructed of more than two parts, and bearings are technically identical to bearings except that they are self-finishing single-part devices. Mechanical bushings are primarily used as support components for fittings to reduce friction and wear between mechanical parts. The bushing is the most important part of the power transformer. Without the series, the power transformer doesn't exist. Compared to rolling, relative motion can be performed by sliding. Also known as sleeve bearings, this term is redundant. Let's take a closer look at these two mechanical parts. The bushing is similar to thin pipes and is most commonly used on machines with rotating or sliding shafts to increase efficiency and reduce vibration and noise. Butcher knives can be used for drilling work on drilling chips, hydraulic external gear pumps, and electric motors. Other common t...

 The rotational force of a ship's propeller is determined by the force generated by the ship's engine that rotates the crankshaft. The crankshaft of the main engine is supported on the connecting rod by the Main Bearings and connected with it. The main function of the Main Bearings is to transmit the load without metal-to-metal contact. This is achieved by the selection of special materials that make up the Main Bearings, which floats when the lubricating oil is supplied to the pins of the rotating crankshaft. Main B earing M aterial P roperties Selecting a marine engine main bearing requires the following characteristics: Corrosion resistance is required to prevent corrosion of bearing materials and related components such as steel balls and housings. Frictional resistance is necessary in order to minimize energy losses between bearings. Good support is required when dynamic loads come into play. You need proficient driving and proficient driving skills Bearings need to suppor...

 If you've heard of Landtopmall , you should know that we have aftermarket diesel engine parts for sale. But, do you know the difference between aftermarket parts and OEM parts? Maybe you do, but a lot of people call us, and no. Aftermarket parts are genuine parts or parts not produced by the company that made the engine. OEM is an acronym for Original Engine Manufacturer, which refers to the company that first manufactured and/or sold engines. For example, Caterpillar and Cummins are the two largest OEMs in the large diesel segment. The general premise is that when an engine needs servicing, only the OEM can provide the correct parts or high-quality parts. Aftermarket parts have bad reviews for tattered, not durable, or improperly installed. But, what's the truth? Sure, OEM accessories are true, but are they really the only good option? OEM Engine Rebuild Kit The Advantages  of Buying an OEM Rebuild Kit The great thing about buying an OEM rebuild kit is that you'll find th...

 The aluminum stone in your engine lives as hell as it burns. If at full throttle 6000rpm the pistons of a petrol engine exploded repeatedly, the metal would heat up to over 600 degrees Celsius, so about 10 tons of force every 0.02 seconds. Lately, that cylindrical Hades has gotten hotter like never before, and only the pistons have the potential to worsen. As automakers pursue greater efficiency, piston producers are preparing for a future in which the most powerful naturally aspirated gasoline engines produce 175 horsepower per liter from 130 now. Tighter conditions are created as the turbocharger and output increase. Over the past 10 years, the operating temperature of the piston has risen by 120 degrees and the peak pressure of the cylinder has risen from 1500psi to 2200. Pistons tell a story about the existence of engines. The crown can show the air holes, the number of valves, and whether fuel is injected directly into the cylinder. However, piston design and technology can a...
