Description
### Product Overview
The transition pipe of the injector is located between the injector valve body and the injector nozzle, serving as a high-pressure fuel transmission channel, continuously conducting the common rail high-pressure fuel. Under long-term high-pressure fuel impact and cold-hot cycle vibration conditions, the outer wall of the pipe wears out and the sealing rubber ring ages, which easily leads to fuel pressure relief leakage, resulting in insufficient injection pressure. This product is standardized in terms of overall length, outer diameter, and sealing groove size. It is produced in a standardized manner and can be replaced along with the disassembly and major repair of the injector when replacing the injector nozzle, suitable for maintenance and repair of heavy-duty trucks and construction machinery common rail diesel engines.
Core advantages of the product
1. **High-strength alloy steel substrate, resistant to high-pressure impact and不易 deform**
The tube is precisely machined from high-quality alloy steel and undergoes surface strengthening treatment. It can withstand high-pressure fuel impact for a long time, and the rod body is not prone to bending or deformation. The outer wall is wear-resistant and resistant to erosion.
2. **Integrated sealing groove structure, precise positioning for installing sealing rings**
Standard sealing ring grooves are reserved on the rod body to ensure the stable positioning of the O-ring. After assembly， it effectively isolates the high and low-pressure oil chambers and prevents bypass pressure relief.
3. **Central through-hole precision oil passage， low fuel flow resistance**
The internal holes are precisely processed, with smooth and smooth inner walls, reducing fuel flow loss and ensuring the complete transmission of oil pressure to the fuel injector， maintaining stable atomization pressure.
4. **Standard dimensions at both ends， excellent assembly coaxiality**
The outer diameters of the head and tail are strictly controlled. After being installed in the fuel injector housing， they are well centered， avoiding assembly skew that causes local wear and leakage.
5. **Resistant to alternating high and low temperature conditions， adaptable to complex working environments**
The material has good thermal stability. Under the condition of engine cold and hot alternation， the size change is minimal， continuously ensuring the sealing of the oil circuit and the performance of fuel transmission.
6. **Each batch undergoes dimensional inspection， consistent parameters of individual pieces**
Samples are taken from each batch for inspection of total length， outer diameter， and the position of the sealing groove. The specifications are uniform， and the stability of large-scale maintenance spare parts assembly is stronger.
