Diesel Generator Tech

Nowadays, more and more generators are made by manufacturers all over the world. Also, the type of generator is various such as portable generator set , silent genset, trailer genset, container genset and even more. However, different types of engines are equipped with generator set. Most often, we can see is gasoline generator, diesel generator, marine generator, petroleum generator. Usually, these generator are similar in size and functionality, but differ on the fuel.  Generator is widely used in various fields such as buildings, home, hospital, mining machine, vessels, real estate, constructions, road, etc. Currently, industrial generators are used most. Here, we will talk about industrial generator and its main components. Before knowing about this type of generator, first we should learn the working principle of generator. An electric generator is a device that converts mechanical energy to electrical energy. But please note that a generator does not a...

Before learning the difference between AC and DC genset, first we should know about what is genset. G enset is mainly composed of engine and generator. Most commercial machines and equipment is AC genset. However, commercial DC gensets are commonly founded in electromagnetic applications. Some are used in Traction applications like subways and trains. Some DC motor-generator sets provide the field currents for large commercial power Alternators/ AC generators as in hydro-electric dams.  Generator working principle: Generator works by moving electrical conductors through a magnetic field. If your generator doesn’t have magnets, it won’t produce electricity. The magnetic field is created by taking some of the generator output voltage and converting it to DC and feeding it to a coil to make an electro magnet. In other words,   the process of converting energy is performed by electromagnetic induction. There are also two types of generators and these produce currents that d...

No matter you choose single phase or three phase generator, its application is different. Usually, for single phase generator, it is normally for residential use. However, three phase generator is primarily for industrial use. If you are looking for a generator to power larger, commercial businesses, you’ll likely want to invest in a three-phase generator, which have a typical voltage of 480. Many large pieces of equipment and electric motors, as well as data centers and industrial areas, will require the power that you can get out of a three-phase generator. While these generators generally cost a bit more than single-phase generators and can require more maintenance, their reliability and unbeatable efficiency can keep larger operations functioning in tip-top shape, at all times. If you are looking for a generator for a rural area, you can choose single phase generator, small equipment don’t require constant, high-voltage power, single-phase used generators provide an eff...

In this article, you will learn how to choose engine air filter and the uses of air filter. Air Filter The dust in the air is the primary reason on abrasion for cylinder liner, piston, piston ring, valves, valve stem guide and other athletic parts, the more the dust in the intake to the engine is the more the abrasion of the engine’s parts is. It is founded by wearing test of engine that the dust less than a diameter 0.001 mm has an very small effect on engines, the dust with a diameter between 0.001 mm and 0.01 mm has measured effect on the engine if the diameter of the dust in the intake is larger than the thickness of the bearing oil film, it will affect the life of the main and connecting bearing and the piston ring. Therefore, to extend the service life of a  diesel generator , it is very important that air filter should be chosen carefully. According to different uses, air filter is divided into normal duty and heavy duty air filters. The minimum efficiency for...

In this article, we mainly introduce the seasonal maintenance checks of  Cummins generator . Clean Cooling System (Autumn) The cooling system must be clean to do its work properly. Scale in the system slows down heat absorption from water jackets and heat rejection from the radiator. Use clean water that will not clog any of the hundreds of small passages in the radiator or water passages in the block. Clean the radiator cores, heater cores, oil cooler and block passages that have become clogged with scale and sediment by chemical cleaning, neutralizing and flushing. Chemical cleaning If rust and scale have collected, the system must be chemically cleaned. Use a good cooling system cleaner and follow the manufacturer’s instructions. Pressure Flushing When pressure flushing the radiator, open the upper and lower hose connections and screw the radiator cap on tight. Use the hose connection on both the upper and lower connections to make the operation easier....

This article will show you the detailed information of diesel engine installation requirements. 1. Installation of the crankshaft During crankshaft installation, the main bearing bolts should be tightened from thrust gear(the third gear) to both ends in order, and in three steps: ① tighten to 60－80 N.m ② tighten to 160－180 N.m ③ tighten to 220－260 N.m During every time, the crankshaft should be rotated to check the mobility. It should be able to rotate freely after the final tightening.The axial clearance should be between 0.1 and 0.27 mm . 2. Installations of the piston and the connecting rod When installing the piston rings, put the surfaces marked upward( the second positive twist ring inner fillet upward). During positioning the piston-connecting rod assembly into the cylinder bore, stagger the joints in turn.  A nd put the arrow marked on the top surface of piston towards the front end of the engine. Remember spreading some clean oil before tight...
