Description
Product Overview
The inline piston fuel pump is driven by the camshaft to make multiple pistons move back and forth to establish high-pressure fuel. The matching governor controls the fuel supply volume to match the engine load, evenly distributing the high-pressure fuel to the six-cylinder engine. Under long-term heavy-duty construction, poor-quality impure diesel washing, alternating high and low temperatures, the piston pairs wear out, the sealing parts age, and the governor mechanism gets stuck, resulting in large deviations in fuel supply volume for each cylinder, power loss, idle wobble, multiple ignition starts, and diesel leakage diluting the engine oil. This product's entire machine piston, fuel outlet valve, and governor are uniformly paired and calibrated at the factory. The installation holes and oil passage thread specifications are standardized. Maintenance can directly replace the entire machine, suitable for six-cylinder heavy-duty trucks, large loaders, mining equipment, and large power fixed diesel generator sets for maintenance.
Core advantages of the single product
High-strength cast aluminum integrated pump body, lightweight and high pressure-bearing without deformation
The entire cast aluminum is integrated and poured, the internal oil channels are integrated without splicing gaps, and the heat dissipation performance is excellent; the thickened outer wall bearing structure can withstand long-term high-pressure fuel impact and road bumps without cracking and leaking, reducing the risk of oil leakage in the oil circuit.
Six independent high-pressure fuel outlets, each cylinder's fuel supply is uniform and stable
The top six standardized fuel outlet assemblies, each group is independently sealed and regulated, the fuel supply stroke is calibrated cylinder by cylinder at the factory, the fuel supply volume deviation between each cylinder is small, the engine runs smoothly, and reduces vibration and black smoke from the exhaust.
Side-mounted integrated mechanical governor assembly, load adaptive fuel supply regulation
The integrated mechanical governor mechanism, with a built-in governor spring and fly block component, can automatically adjust the fuel supply volume according to the engine speed, providing sufficient fuel supply for heavy-duty climbing, stable idle speed without drift, and sensitive and non-stuck governor response.
Front-end sealed drive main shaft, red auxiliary sealing ring to prevent leakage
The main shaft assembly position is equipped with an oil-resistant sealing structure to block diesel leakage caused by the reciprocating motion of the main shaft, avoiding fuel flowing into the gearbox to dilute the lubricating oil, and prolonging the service life of the internal components of the fuel pump.
Multiple specifications reserved oil circuits and installation holes, strong assembly compatibility
The shell reserves low-pressure oil inlet holes, return oil holes, and multiple fixed installation flange holes, precise alignment, no need for additional modification of gaskets, suitable for the installation of corresponding engine bases.
The entire machine is calibrated on the professional fuel pump test bench, no secondary calibration is required when installed
The entire machine has been tested on the professional fuel pump test bench, the fuel supply lead angle, fuel supply volume of each cylinder, and governor range are all calibrated accurately, after installation, it can directly restore the standard power output of the equipment, significantly reducing the debugging time. Applicable scenarios
It is suitable for heavy-duty freight trucks with inline six-cylinder mechanical injection system, large mining loaders, agricultural large tractors, high-power fixed diesel generators. It is applicable for long-distance heavy-load freight transportation, 24-hour continuous operation in mines, high-intensity operations in farmlands, and replacement of fuel supply components in heavy-duty diesel engines operating in high-temperature, vibration, dust, and impurity diesel environments.
