Product Description
LONGBENG mainly engages in development and manufacture of fuel injection system products of diesel engines, including mechanical fuel injection pumps of A, AD, PM, EP9, PA, P7100, P8500, P9, PZ, VE and other series, electronic unit pumps, electronic pumps, fuel injections, high-pressure common rail fuel injection systems, etc. With an annual production capacity of 600,000 fuel injection pumps, LONGBENG provides high-quality auxiliary products for over 20 major manufacturers of diesel engines in our country, including Weichai, Yuchai, Changchai.,etc. LONGBENG produce a great variety of high-tech, high-quality goods which are appropriate for diesel engines with a power ranging from dozens of horsepower to two thousand horsepower. It meets Euro Ⅱ, IIIemission standards and are widely applied to automobiles, ships, generators, engineering machinery and other power machinery.
LONGBENG took the lead in passing TS16949 quality management system certification among fuel injection pump industry.
The LONGBEGN high-pressure fuel pump is the most important system of the diesel engine. Its function is to increase the pressure of diesel, and according to the requirements of the working process of the diesel engine, deliver diesel to the combustion chamber at a fixed time, quantitative and pressure, and ensure rapid fuel supply, clean fuel stop and no oil dripping. The high-pressure oil pump is driven by a camshaft, and its purpose is to convert the low-pressure fuel from the oil pump into high-pressure. In order to reach the oil supply pressure.Because it has an absolutely important direct impact on the main performance indicators of the engine such as power, fuel economy, emissions and noise, as well as reliability and durability, people often compare it to an engine heart when emphasizing the importance of the fuel pump.
LONGBEGN high-pressure fuel pump is produced by advanced casting technique and High precision processing equipment with advanced assembly technology and perfect testing methods. It has the characteristics of high pressure, large flow, compact structure, low noise, long life, fast response, strong impact resistance, etc.

Work principle
1. The fuel transfer pump pumps the fuel from the fuel tank, passes through a filter with an oil-water separator, and enters the high-pressure pump through the fuel inlet pipe.
2. The fuel transfer pump allows the fuel to enter the lubrication and cooling circuit of the high-pressure pump through the orifice of the pressure relief valve. The camshaft makes the plungers of the three pumps move up and down according to the shape of the cam.
3. The fuel supply pressure exceeds the opening pressure of the pressure relief valve. The fuel transfer pump can make the fuel enter the plunger cavity through the high-pressure pump inlet valve. The plunger of the high-pressure pump is moving downwards (suction stroke). At the dead point, the oil inlet valve is closed.
4. When the common rail pressure is reached, the compressed fuel enters the high-pressure cycle (oil circuit). The plunger continues to supply fuel until it reaches the top dead center (fuel supply stroke), the pressure decreases, causing the fuel outlet valve to close, the fuel pressure still in the plunger cavity also drops, and the plunger (pump oil plug) goes down again sports.
5. As long as the pressure in the plunger cavity drops below the oil supply pressure of the oil supply pump, the oil inlet valve opens again and the oil pumping process starts again.

Packing & Delivery
Before packaging, we generally evaluate the fragility of the goods and the value of the goods, and then select the appropriate inner packaging materials. Secondly, we consider that various situations may occur during transportation, and we have requirements for the compression, shock and water resistance of the outer packaging of the goods. For multi-way valve, we use wooden box to pack.
About the shipping method, multi-way valve usually use air and sea shipping methods, and the port can be specified by the
customers.
