High Quality Diesel Fuel Injection System Pump Head Rotor 1 468 374 020 Engine Parts VE Pump 1468374020

Diesel pump head, like the heart pacemaker of diesel engine, occupies a pivotal position in the whole power system. It is a set of precision machinery and efficient fluid control in one of the key components.

The pump head is extremely well designed. Usually made of strong and corrosion-resistant metal, it contains a number of core components such as a plunger, a sleeve, and a delivery valve. The plunger reciprocates inside the sleeve, and this movement is a key part of fuel delivery. When the plunger goes down, the chamber volume of the pump head increases, the pressure decreases, and the fuel can be sucked in smoothly; when the plunger goes up, the chamber volume decreases, and the fuel is compressed; once the pressure reaches the opening threshold of the outlet valve, the fuel will be accurately transported to the injector nozzle through the outlet valve, and then be sprayed into the combustion chamber of the diesel engine to participate in combustion and do work.

The accuracy and stability of its work is directly related to the performance of the diesel engine. High-quality pump head can ensure the precise control of fuel injection volume, so that the fuel and air to achieve the best mixing ratio, thus ensuring the strong power output of the diesel engine, good fuel economy and low exhaust emissions. The pump head can flexibly adjust the fuel supply pressure and flow rate according to the demand under different working conditions, whether it is idling at low load or heavy duty operation at high load.

In addition, the durability of the pump head is also its important characteristic. Facing the high temperature, high pressure and complex mechanical vibration environment of diesel engine operation, it performs its mission stably for a long time by virtue of its exquisite manufacturing process and high quality materials. From large industrial diesel engines to small and medium-sized diesel engines for agricultural irrigation, transport and other fields, the pump head provides a solid guarantee for the continuous operation of all kinds of equipment with its reliable performance, and has become an indispensable core element in the field of diesel technology, which continues to drive the diesel technology towards a more efficient, environmentally friendly and more durable direction of continuous evolution and development.
