High Pressure Pump Overflow Pressure Screw Valve 2417413082, replacement overflow valve for diesel high pressure fuel pumps
No.2417413082
2417413082 Special分流 overflow bolts for electronic control common rail high-pressure oil pumps, precise limit-positioning分流 components for adjusting the fuel分流 flow in the oil circuit and balancing the internal oil pressure. They are made through integrated quenching alloy steel CNC machining. The upper part features an integrated hexagonal disassembly and clamping head. The middle section of the screw has bilateral symmetrical分流 and pressure relief holes， and the bottom has a central oil passage that is贯穿. Factory testing has completed a complete set of bench tests for flow rate， high-pressure bearing capacity， and size matching. They solve problems such as internal oil pressure imbalance in the oil pump， deviation in fuel supply flow， rail pressure fluctuations， intake of air in the low-pressure oil circuit， and difficulties in cold start and ignition. They can be replaced and repaired independently as a single piece without the need to disassemble the entire internal components of the oil pump.
Product Overview The分流溢流 screw is assembled within the internal oil circuit of the high-pressure oil pump. It distributes the fuel flow through the side wall diversion holes， buffering the impact of high-pressure fuel and stabilizing the base oil pressure inside the oil pump. Under long-term conditions of thousands of bar of high-pressure fuel erosion， impurities of diesel particles wear， and alternating cold and hot vibrations in the engine compartment， the inner wall of the diversion holes may wear and enlarge， and the threaded sealing surface may be scratched. This may result in imbalance in the oil circuit， fluctuating oil pressure， slower pressure building-up speed of the oil pump， idle equipment shaking， and weak power output under heavy load. This product has standardized specifications for the threaded part， diversion hole diameter， and hexagonal head size. By simply replacing the diversion screw at the oil circuit end of the oil pump during disassembly， the oil pressure imbalance fault can be repaired. It is suitable for large-scale mining excavators， heavy-duty wheel loaders， long-distance heavy trucks， and the maintenance of electric control common rail diesel engines for large power fixed diesel generators. Core Advantages of the Single Item The high-quality alloy steel is processed by CNC machining as a whole， resistant to pressure and wear， and not prone to deformation. The overall material is high-temperature quenched alloy steel， which is formed through a combined process of turning and milling. It has high hardness and is not likely to develop scratches or deformation of the hole diameter under long-term high-pressure fuel erosion. It can maintain the standard diversion flow rate and stable oil circuit oil pressure for a long time. The integrated hexagonal clamping head at the upper end allows for controlled torque during disassembly without damaging the threads. The standard hexagonal limit head at the top is compatible with standard socket wrenches， ensuring uniform force during disassembly and assembly， and preventing screw torsion deformation or external thread slippage， thereby guaranteeing the sealing effect of the assembly. The symmetrical diversion and pressure relief holes on both sides evenly distribute the fuel diversion and buffer the impact of high-pressure media. Two sets of symmetrical circular diversion holes are set in the middle section of the screw to divert the fuel and disperse the impact force of high-pressure media， reducing oil circuit vortex wear and balancing the fuel flow in each cavity of the oil pump， eliminating severe fluctuations in oil pressure. The standard precision rolled outer threads ensure a tight fit and no leakage of air intake. The regular rolled outer threads at the lower section are precisely controlled in terms of pitch and outer diameter tolerance， fitting tightly after being screwed into the oil pump cavity， preventing fuel leakage and air suction into the oil circuit， and avoiding oil pump suction failure and pressure relief. The central oil passage at the bottom runs through the center， ensuring smooth oil flow without any blocked or dead corners， reducing the probability of oil circuit blockage and oil supply attenuation in the oil pump. Each single diversion screw undergoes independent flow and pressure-bearing capacity testing before assembly， eliminating the need for secondary calibration. The factory parameters are unified， directly matching the corresponding oil pump oil circuit cavity， shortening the time for oil pump disassembly and debugging.
