The important parts of its main body are strictly produced in accordance with the international advanced technology level from materials, processing technology to processing accuracy. The special design and special processing technology ensure that the engine has good stability and durability.
2)The gantry cylinder block is adopted, and the cylinder block and cylinder head are cast by high-strength alloy cast iron and formed by multi-process machining. It has sufficient mechanical strength and rigidity, and the maintenance of the unit is convenient, the maintenance cycle and the life of the whole machine are long, which greatly saves the operating cost.
3)The four-valve design per cylinder increases the intake and exhaust valve area, the intake and exhaust are sufficient, the intake volume is increased, the torque and power of the engine are greatly improved, and the load-adding capacity of the unit is also improved.
4)The crankshaft with integral twisted forging fully balanced structure and fillet quenching is integrally forged from high-strength alloy steel, which improves the overall strength and rigidity, prolongs the service life of the crankshaft, and improves the running stability and reliability of the whole machine.
Using turbocharging and high-efficiency intercooler, the air supercharging and cooling effects are good, which can effectively ensure the charging coefficient of the gas engine.
WT series gas engine monitoring and control system:
The WT series gas generator monitoring pit system has the characteristics of perfect integration of regulation, control, self-test and safety protection. The specific introduction is as follows:
 

1) WT series gas engine combustion control system:
It uses an electronic adjustable Venturi mixer imported from the United States and other countries, which can adapt to various gases with methane concentrations ranging from 20% to 100%. After the air and gas are mixed, the optimal air/fuel ratio is automatically adjusted electronically. Combined with the uniquely designed combustion chamber, the gas is fully burned, achieving lean combustion, reducing gas consumption, and improving the thermal efficiency of the engine. The electrical efficiency of the generator set can be as high as 34% or more (the heat consumption rate of the unit is ≤10MJ/kW·h)

  2) The high-precision gas engine-specific speed governor and actuator are used, which have the advantages of high speed regulation accuracy, strong resistance to sudden load, and fast recovery time, making the unit run more smoothly and reliably, the control more precise, and better adapted to different types of loads of users.

3) WT series gas engine electronic control ignition system:
The electronic ignition system is developed jointly by international or domestic professional manufacturers, including Hall sensors designed specifically for the characteristics of this type of gas engine, dedicated ignition modules, ignition coils, and high-voltage wires. It has the characteristics of accurate ignition timing and high ignition energy. It extends the service life of the spark plug, improves the starting performance of the unit, greatly reduces the probability of detonation, and improves the stability of engine operation.

Equipped with AC generators of famous domestic brands:
Leroy Somer, Mecc Alte, Watt and other generators, whether from the perspective of electrical, torque or mechanical matching structure characteristics and dynamic mechanical indicators, the generators have good matching performance.
1) Adaptability to various environments, especially suitable for harsh environments such as landfills, sewage treatment plants, coalbed methane, oil fields, etc.
2) Optimized winding design ensures better performance. Whether in 50Hz or 60Hz, there are multiple winding forms to meet the voltage requirements of different usage occasions. The generator stator winding is designed in a standard way and has good performance under distorted load conditions.
3) High electrical efficiency ensures that the unit provides more power.
 

 

The genset control system includes a multi-function control panel, a gas control box, an automatic synchronization control module, an automatic load distribution module, an on-site signal acquisition system, a remote communication interface, and a dedicated control cable.
