How to Solve Water and Oil Leakage in Diesel Generator

In the process of using diesel generator set, soft rubber pipe is easy to rub with the parts around it, and it is easy to wear and tear oil leakage in the long run. However, most of the fuel supply system of diesel generator set uses soft rubber tube, so it is not easy to find the oil leakage point. Below are instructions provided by Starlight Power small make up to teach you a few diesel generator unit pipeline leak spot check method. Method one: exhaust the air from the diesel generator unit, then start the unit to find out the leak point. Method two: release the gas screw of the unit injection pump and release the oil from the hand oil pump. If it is found that the discharge screw starts to discharge a large amount of bubble oil, and the bubble still does not disappear after the repeated hand pump, it can be determined that there is a leak point in the low pressure oil pipeline from the oil tank to the oil pump section. The pipeline should be removed, pressure ...

How to Adjust Generator Voltage by AVR

Voltage regulator (referred to as AVR) is designed for AC brushless generators with fundamental wave, harmonic compound excitation or permanent magnet generator excitation (PMG system). AVR (Automatic voltage regulator) is an instrument that adjusts voltage by means of automatic control device. Voltage regulator realizes the automatic regulation of generator output voltage by controlling the excitation current of generator AC exciter. Generator voltage regulator can be used for ordinary 60/50Hz as well as medium frequency 400Hz single or parallel generators. An AVR is at the heart of devices often called power conditioners or power stabilizers. The typical power conditioner is an automatic voltage regulator combined with one or more other power-quality capabilities, such as: 1) Surge suppression 2) Short circuit protection (circuit breaker) 3) Line noise reduction 4) Phase-to-phase voltage balancing 5) Harmonic filtering, etc. Power conditioners a...

Guides to Reduce the Wear of Diesel Generator Parts

While the diesel generator is running the load, it is also the process of mutual wear of the parts of the diesel generator itself. Starlight Power – Diesel Generator Manufacturer recommends that users minimize the wear between the components of the gensets. Reducing the wear of the parts is also a way to extend the service life of the unit. Here are some effective ways to reduce wear of the generator parts. The quality of the fuel and lubricant of the diesel generator set  should be matched with corresponding specification of generating set. If diesel contains sulphur or other impurities, acid and other corrosive substances will be generated during the combustion process to accelerate the wear of the cylinder; too much heavy fraction in the diesel fuel will easily form carbon deposits after combustion, abrasive wear is generated between the piston ring and the cylinder; viscosity of the diesel has an effect on the formation of the mixture and the reliab...

Maintaining Cummins Diesel Generator Set

Maintaining Cummins diesel generator set in Autumn: 1. Cleaning cooling system The cooling system must be cleaned in order to make it work properly. The scale in the system reduces the heat it absorbs from the water jacket and releases to the radiator using clean water to avoid blocking the radiator and hundreds of tiny waterways in the cylinder block. For radiator cores, heater cores, oil coolers and waterways in cylinder blocks blocked by scale and sediment, chemical cleaning agents are used to wash, neutralize and flush. In order to ensure the cooling system to work effectively, the DCA water filter is used to prevent rust and scale formation. If DCA is used, the cooling system must be chemically cleaned. Use a good cooling system cleaner, such as sodium bisulfate or oxalic acid, then neutralize and rinse. Flush radiators and cylinder blocks before adding antifreeze, or install water filters on used or overhauled engines. When flushing the radiator und...
