Description
### Product Overview
The fuel pump head is a core component of the distributed diesel injection pump. It uses the reciprocating motion of the plunger to establish fuel pressure and distributes high-pressure fuel in accordance with the sequence of the cylinders. Under the long-term erosion by impure diesel and the high-frequency reciprocating impact conditions, the plunger and the distribution surface will wear out, and the springs will fatigue and deteriorate, which can lead to insufficient fuel supply pressure, uneven fuel supply among cylinders, and result in reduced power and vibration during operation. This product has standardized processing for the installation holes and oil passage layout. When the distribution pump needs to be disassembled for major repairs, the entire set can be replaced quickly, restoring the fuel supply performance. It is suitable for the maintenance and repair of light trucks, construction machinery, and diesel engines.
Core advantages of the product
1. **High-strength cast iron housing, resistant to pressure and wear, and not prone to deformation or leakage**
The housing is made of high-quality cast iron and is precisely machined. It has sufficient structural rigidity and can withstand the internal fuel pressure without deforming. The inner wall of the oil passage has been precisely processed to reduce impurity accumulation, and it is not prone to cracking or oil leakage under long-term working conditions.
2. **High-precision plunger distribution component, with strict grinding clearance**
The plunger and distribution plate are precisely matched and ground. The sealing performance is excellent, and the leakage of high-pressure fuel is small, ensuring sufficient fuel supply pressure. The fuel supply volume of each cylinder is uniform and consistent.
3. **Formed high-strength pressure spring, with lasting elasticity and not prone to fatigue**
The two sets of pressure springs are treated with tempering of high-quality spring steel. They do not become soft or deformed easily during repeated compression over a long period, and can stably maintain the plunger stroke, ensuring continuous fuel supply capability.
4. **Precisely positioned installation holes, convenient for disassembly and alignment**
The position of the flange installation holes is standard. They directly match the assembly points of the oil pump housing. Maintenance and assembly do not require adjusting the hole positions, reducing the difficulty of assembly.
5. **Resistant to cold and hot alternating conditions, suitable for outdoor variable working environments**
The entire metal component has good thermal stability. Under low-temperature cold start, long-term heavy-load high-temperature alternating conditions, the clearance changes are small, and the fuel supply performance is stable.
6. **Inspection of supply oil flow and pressure at factory, uniform performance of each piece**
Each batch of assemblies undergoes sampling tests for fuel supply pressure and uniformity of each cylinder. The parameter consistency is high, and the stability of the maintenance and assembly is stronger.
