Here are some key points for selecting oil pumps and injectors for high-pressure common rail systems in agricultural machinery equipment:
Considering compatibility: Different brands and models of agricultural machinery engines have different requirements for fuel injectors. It is necessary to choose fuel injectors that are fully compatible with the engine model, otherwise it may lead to decreased engine performance, increased fuel consumption, or even damage.
Pay attention to performance parameters:
Injection pressure: The injection pressure of high-pressure common rail systems is usually between 160-200MPa. Choosing fuel injectors with high injection pressure and precise injection quantity control can help improve engine performance, making fuel atomization more uniform and combustion more thorough.
Fuel injection quantity: It is necessary to select fuel injectors that can accurately control the fuel injection quantity according to the working load, speed and other requirements of the agricultural machinery engine, in order to meet the fuel supply under different working conditions.
Injection angle: The injection angle needs to match the structure and intake mode of the engine combustion chamber, so that the fuel can be evenly distributed in the combustion chamber and achieve good combustion effect.
Emphasis on manufacturing materials and structural design: High quality fuel injectors are made of special wear-resistant materials that can withstand high working pressures and extreme environmental conditions. Meanwhile, a well-designed structure should be easy to disassemble and clean to extend its service life.
Consider after-sales service: Ensure that the selected fuel injector has good after-sales support and a reasonable warranty period, so that problems can be solved in a timely manner during use, avoiding high maintenance costs.
Reference brand reputation: You can refer to some brands with good market reputation, such as Bosch, Delphi, etc., which have performed well in technological innovation and product quality. For some small brands, it is necessary to conduct thorough investigation and evaluation in terms of quality and after-sales service.
