Description
The pump head of the distribution pump is assembled inside the VE-type distribution fuel injection pump and is the core component for fuel distribution control. It completes high-pressure fuel measurement, pressurization, and orderly distribution according to the engine's operating conditions, delivering fuel to each cylinder. Over time, due to the wear of the internal precision friction surfaces, faults such as uneven fuel supply, difficult starting, decreased power, and idle vibration may occur. This product is precisely manufactured in accordance with the original factory dimensions. For major repairs of the fuel pump, this component can be replaced separately to restore the fuel supply accuracy of the pump and is applicable for maintenance of various diesel vehicles and construction machinery fuel injection systems.
Core advantages of individual products
1. **High-strength alloy steel material, resistant to wear and fuel corrosion**
The main steel is strengthened through heat treatment. The friction working surface has sufficient hardness, and it is not prone to rust or scratches even under long-term high-pressure diesel flushing, thus extending the service life.
2. **High-precision grinding processing, standard internal clearance**
The key coupling surfaces are precisely ground, with precise gap control. The oil pump operates with stable oil pressure, effectively reducing fuel leakage.
3. **Integrated molding structure, stable positional tolerance**
The flange installation surface and the center matching position are strictly controlled for coaxiality. The assembly fit is high, and it is not easy to be misaligned or leak during installation.
4. **Balanced and stable fuel supply, optimizing engine operating conditions**
The fuel distribution is consistent, improving idle stability, enhancing power output, and promoting more complete combustion.
5. **Standard external dimensions, direct replacement without additional processing**
The flange hole spacing, outer diameter, and oil passage interface are consistent with the original specifications. The oil pump can be directly replaced during disassembly and major repair, saving debugging time.
6. **Multiple precision inspections at factory, good batch consistency**
Sampling inspections are conducted on external dimensions, flatness, and inner hole accuracy. The quality of large-scale production is stable.
