Description
The pump head of the distribution pump is assembled inside the VE type distribution fuel injection pump and serves as the core component for fuel distribution control. It completes high-pressure fuel measurement, pressure increase, and sequentially delivers fuel to each cylinder according to the engine's operating conditions. After long-term use, the precise friction surfaces are prone to wear, which can cause uneven fuel supply, difficulty in starting, insufficient power, and idle vibration, among other faults. This product is precisely manufactured according to standard dimensions. For major overhauls of the fuel pump, this component can be replaced independently to restore the fuel pump's supply accuracy and meet the maintenance needs of various diesel vehicles and construction machinery fuel injection systems.
Core advantages of individual products
1. **High-strength alloy steel raw materials, resistant to wear and fuel corrosion**
The main body has undergone heat treatment to enhance strength, and the precision working surfaces meet the hardness standards. It can withstand the impact of high-pressure diesel oil for a long time without rusting or being scratched, thus having a longer service life.
2. **Multiple precision grinding processes, precise internal clearance**
The key coupling surfaces are precisely ground, with standardized gap control. The oil pump operates with stable oil pressure, reducing fuel leakage.
3. **Integrated precision shell structure, stable positional tolerances**
The flange installation surface and the center matching position are strictly controlled for coaxiality. The assembly is tight and prone to avoid installation misalignment and oil leakage problems.
4. **Uniform and stable fuel distribution, improving engine operation conditions**
The fuel supply is excellent in consistency. The idle operation is smoother, the power output is smooth, and the fuel combustion is more complete.
5. **Standard external installation dimensions, direct replacement for maintenance without processing**
The flange hole distance, center outer diameter, and oil passage specifications match the original standard. The oil pump can be directly assembled for major disassembly and repair, saving debugging time.
6. **Multiple precision inspections of the finished product, high consistency of the same batch specifications**
The factory conducts sampling inspections for external dimensions, sealing planes, and internal hole accuracy. The quality of batch supply is stable.
