Description
Product Overview
The pump head of the distribution pump is the core hydraulic component of the diesel injection pump. It is constantly subjected to the high-pressure fuel flushing. The rotor and the piston are prone to wear and internal leakage, resulting in imbalance of the supply pressure and deviation of the fuel supply volume for each cylinder, which leads to the reduction of engine power and vibration during operation. This product has standard external installation dimensions, high assembly accuracy, and is easy to assemble. It is widely applicable for the maintenance and replacement of fuel pumps in construction machinery, agricultural tractors, light diesel vehicles, and diesel generator sets.
Core advantages of the product
1. **High-quality alloy steel substrate, resistant to wear and high-pressure corrosion**
The main alloy steel is precisely forged, and the friction working surface is strengthened through heat treatment. It can withstand various diesel medium erosion and does not deform or leak under long-term high-pressure conditions.
2. **Micron-level matching grinding, strong sealing stability**
The rotor, piston, and sleeve are precisely matched through grinding, with precise gap control. The leakage of high-pressure fuel is small, the supply pressure is stable, and the fuel supply to each cylinder is uniform.
3. **Finished machine assembly inspection**
Each assembly undergoes multiple bench tests for sealing, fuel supply volume, and pressure, resulting in high performance consistency and lower machine failure rate.
4. **Standard size dimensions, no modification installation**
The flange installation dimensions are universal, eliminating the need for secondary processing, and saving time and effort for maintenance and disassembly.
5. **Rich application scenarios**
Suitable for agricultural tractors, light diesel trucks, small engineering equipment, diesel generator sets, and other diesel-powered equipment.
