Description
### Product Overview
The high-pressure fuel injection pump receives power from the engine and uses the internal piston components to establish high-pressure hydraulic pressure. It simultaneously delivers the fuel medium to the fuel injection system to complete the injection work. Under long-term load operation, impurities in the oil products, continuous vibration under high and low temperatures, and wear and aging of the internal piston sealing surfaces, valve components, and sealing parts can cause unbalanced fuel supply pressure, oil leakage, decreased engine power, and increased black smoke emissions from the exhaust. This product is standardized in terms of installation dimensions, oil circuit interface specifications, and power installation points. During maintenance, the entire fuel injection pump can be directly replaced, eliminating the need for individual adjustment of internal components. It is suitable for maintenance and use of diesel engines for excavators, rotary drilling rigs, and heavy construction machinery.
Core advantages of individual products
1. **Thickened segmented alloy housing, high-strength, pressure-resistant, deformable-resistant, and leak-proof**
The housing is made by thickened alloy through CNC precision processing. The surface is treated for rust prevention. It is compatible with the engine mounting base structure and can withstand long-term high-pressure medium impact, resist oil corrosion and temperature changes. The housing is not prone to cracking, and the threads are not prone to slippage. It can maintain the oil circuit sealing stability for a long time.
2. **Integrated one-piece oil delivery structure, smooth and stable oil flow, stable oil pressure**
The integrated oil delivery component is built-in without any extra external pipelines, reducing the risk of oil leakage. It ensures continuous medium delivery, stabilizes the system working oil pressure, and improves the phenomenon of insufficient combustion and black smoke emission caused by insufficient fuel supply.
3. **Built-in precision plunger drive component, rapid and no-delay pressure response**
The internal plunger and control valve components have high processing accuracy, standard mating clearance, and sensitive pressure establishment response. They precisely control the oil supply pressure and flow range, ensuring smooth engine idle operation and smooth heavy-load power output.
4. **High-precision inlet and outlet oil connectors, atomized medium delivery, stable oil supply**
Each oil port channel is precisely processed. The resistance of medium flow is balanced, ensuring continuous and stable oil supply. It effectively reduces the generation of carbon deposits inside the engine, optimizes fuel consumption levels, and lowers exhaust emissions.
5. **Multi-layer oil-resistant sealing structure, bidirectional anti-leakage, preventing air from entering the oil circuit**
Internal assembly of multiple specifications of oil-resistant sealing rings, layer-by-layer isolation of high and low pressure oil chambers, prevents medium leakage outward; at the same time, it prevents air from being sucked back into the oil circuit after shutdown, solving the problem of slow start-up oil circuit intake and pressure establishment.
6. **Full-item factory testing of the entire machine chassis, no need for secondary adjustment when installed**
Each single jet pump independently completes pressure testing, sealingity, oil supply flow, and pressure response detection calibration. The performance parameters are unified. After assembly, it quickly restores the original engine power performance, shortening the time for oil circuit maintenance and debugging.
