Components of Cummins PT Fuel System

When it comes to Cummins generator, it is well known that the gensets have good quality, low fuel consumption, low noise, big output power and reliable performance. The reliable stability, economy, power performance, durability and environmental safety is welcomed by customers. In last article, we talk about CCEC Cummins diesel engines operating principles. Well, in this article, you will learn what are the major components of its PT Fuel System. Fuel System The PT fuel system is used exclusively on Cummins Diesels. The identifying letters, “ PT ” are an abbreviation for “ pressure-time ” . The operation of the Cummins PT Fuel System is based on the principle that the volume of liquid flow is proportionate to the fluid pressure, the time allowed to flow and the passage size through which the liquid flows. To apply this simple principle to the Cummins PT Fuel System , it is necessary to provide: 1. A fuel pump. 2. A means of controlling pressure of

Leroy-Somer Alternator AVR R450

1 - GENERAL INFORMATION of Leroy-Somer Alternator AVR R450 1.1 - Description The R450 AVR is supplied in a casing designed to be mounted on a panel with dampers. - Operating temperature: - 30°C to + 65°C. - Storage temperature: - 55°C to + 85°C. - Shocks on the base: 9 g depending on the 3 axes. - Vibrations: less than 10 Hz, 2 mm half-peak amplitude 10 Hz to 100 Hz: 100 mm/s, above 100 Hz: 8 g. The AVR is IP00, it must be incorporated in an environment which ensures it a IP20 protection. 1.2 - Characteristic The connection is realised by “Faston” connectors and the voltage sensing is single - phase. 2 - POWER SUPPLY Both the SHUNT/AREP & PMG excitation systems are controlled by the AVR. 2.1 - AREP excitation system With AREP excitation, the electronic AVR is powered by two auxiliary windings which are independent of the voltage sensing circuit. The first winding has a voltage proportional to the   alternator   main voltage (Shunt characteristic),
