Product Description

1. Main structure of the biogas generator set

Biogas generator sets include biogas-fueled reciprocating internal combustion engines, alternators, electrical parts, control devices, cooling systems, lubrication systems, exhaust systems, fuel systems, and auxiliary equipment. Except for the exhaust pipe and silencer of the exhaust system, they are mounted on a steel chassis. The generator set is a fixed permanent installed generator set. The steel underframe is mounted to the concrete foundation.


2. Main structure of the biogas engine

The engine's technology is from the German MAN and represents the most advanced engine in the world. It has undergone rigorous bench test, and its life is longer than other domestic engines. Its functional components and functional design make its components. The number is reduced by about 25% compared to conventional engines, and the maximum program reduces sealing components, greatly reducing the risk of "three leaks". The cylinder parts of the engine are made of vermicular graphite cast iron, which has high tensile strength and fatigue strength. Compared with the gray cast iron collective, the strength is increased by 75%.

3. Technical characteristics of gas engine

Inheriting advanced technology and excellent quality of German MAN's engine. And with below characteristics (1) Iridium spark plugs significantly the service life of spark plugs, (2) EControls new generation of CFV gas supply system ensures the high reliability, (3) Electronically controlled pressure regulating air inlet guarantees low gas consumption and low exhaust temperature, (4) Wide domain oxygen sensor controls fuel-air ratio which ensures economic and environmental emission standard, (5) All condition closed-loop control to achieve the optimal combustion



4. Alternator

The brushless constant-voltage synchronous alternators are of the self-excited type with an electronic voltage regulator integrated in the excitation system. They are used as main or standby units in land based power installations and for ships' electrical systems and can be driven by internal combustion engines or gas, steam and water turbines and electric motors.

Structure: 
The alternator comprises the main machine exciter and excitation system. The main machine is of revolving magnetic field with cylindrical rotor and damper winding. The exciter is revolving armature machine. The exciter power is supplied to the rotor of the main machine via rotating rectifiers.



5. Genset control panel

The control panel adopted Harsen controller and can detect the current, voltage, speed, frequency, power, engine cooling water temperature, engine oil pressure, exhaust temperature, number of starts, running time, etc. of the unit. The screen also designed a variety of necessary protections for the generator set to ensure safe and stable operation of the unit. The main protections include high water temperature, low oil pressure, overspeed, high temperature, over voltage, under voltage and low frequency. The control panel provides DC power switch, emergency stop button, and unit fault alarm indication.

The automatic generator set adopts automatic control system, which can realize self-starting, self-regulating, self-adjusting frequency, automatic load-carrying, automatic fault alarm, automatic control, etc., to achieve digital management, the generator is always ready to start, the main power supply is cut off or When the fault occurs, the standby unit starts immediately and is put into the load operation at 15S. The unit is interlocked with the external power. The automatic switching between the mains and the standby unit is realized through the ATS of the Party A. When the utility power is restored, the standby unit exits and enters the shutdown process. When the startup is unsuccessful for 3 consecutive times, it can issue a startup failure alarm, and automatically stop when the unit fails, and provide alarm signal information.
