Description
### Product Overview
The injector pressure stopper is assembled inside the common rail injector and is located between the electromagnetic valve and the control valve. It is responsible for transmitting the electromagnetic force and precisely controlling the opening and closing of the valve core. Under conditions of long-term high-frequency reciprocating impact and frictional erosion caused by impurities in fuel, the pressure-bearing end face of the stopper will wear and its height dimension will change. This will cause the timing of injector opening and closing to deviate and lead to poor sealing, resulting in injection disorder. This product is standardized in terms of its size and coaxiality. When the injector is disassembled for maintenance, the accessories can be replaced separately, effectively restoring the injection control accuracy. It is suitable for maintenance of common rail engines of diesel construction machinery and heavy freight vehicles.
Core advantages of the product
1. **High-strength wear-resistant alloy steel base material, resistant to impact and not prone to deformation**
The push rod is precisely forged from high-quality alloy steel, with the working surface hardened. It can withstand frequent impacts without developing pits or deformation, and is resistant to long-term erosion by high-pressure fuel.
2. **Integrated stepped structure, stable coaxial motion accuracy**
The overall integrated manufacturing process strictly controls the concentricity of the axis line. The reciprocating motion is unlikely to shift or get stuck, ensuring that the thrust is uniformly transmitted to the control valve component in a vertical manner.
3. **High-precision polished pressure-bearing end face, uniform force transmission and stability**
The pressure-bearing planes at both ends are precisely ground, with strict control over the flatness. After assembly, the force is evenly distributed, avoiding local stress concentration that may cause deviation in the opening and closing sequence.
4. **Size tolerances are strictly controlled, and disassembly, replacement, and adaptability are strong**
The overall outer diameter, total height, and stepped dimensions precisely match the corresponding fuel injector housing. Maintenance and assembly do not require trimming, reducing the time for rework.
5. **Resistant to alternating high and low temperature conditions, adaptable to complex working environments**
The material has excellent thermal stability. Under alternating high-temperature and cold-start conditions, the size is unlikely to change, continuously ensuring the transmission accuracy.
6. **Each batch undergoes dimensional inspection, and the parameters of each piece are stable**
Each batch of products is sampled for inspection of total height, end face flatness, and outer diameter. The specifications are uniform, and the stability of large-scale maintenance and spare parts assembly is stronger.
