Description
Product Overview
101402-8000 Series In-Line Mechanical Injection Pump is a core high-pressure fuel supply component of the electrically controlled diesel engine core. It compresses fuel through the reciprocating motion of the internal pistons to form injection pressure. It is equipped with a mechanical speed regulation mechanism to automatically match the fuel supply volume for different loads. If the pistons of the old pump are worn, the speed regulation mechanism gets stuck, or the sealing gasket ages, the oil pressure will decrease and the engine will be weak. The entire machine can be replaced to repair all fuel supply faults at once. It is suitable for light trucks, small loaders, agricultural tractors, fixed diesel generator sets for major overhauls and replacements.
Unique Core Features of the Single Product
Integrated thickened cast aluminum pump body, multi-ribbed heat dissipation with long-term pressure-bearing capacity
The entire machine is cast in one piece with high-pressure aluminum, and the external reinforcing ribs of the pump body enhance structural strength and accelerate the heat dissipation of the cylinder body at high temperatures, slowing down the aging of internal sealing components, and making it less prone to deformation and leakage under long-term high-pressure operation.
Four independent oil outlet connectors, pre-installed with blue dust-proof protective caps
Four sets of standardized oil outlet threaded interfaces are evenly arranged on the top of the pump body, paired with blue plastic protective plugs. They can isolate dust and impurities during storage and transportation, preventing fine particles from entering the oil circuit and causing the piston and injector to get stuck. No additional protection is required before installation.
External mechanical speed regulation control bracket, manual precise regulation of fuel supply volume
The side integrates a metal speed regulation swing arm and adjustment screw combination structure. It can adjust the fuel supply stroke manually according to the equipment load, and automatically stabilize the fuel supply volume in idle and heavy-load conditions. The mechanical structure is stable, without the risk of electric control failure, and is suitable for harsh and power-free outdoor working environments.
Multi-channel partitioned oil circuit interfaces, clear and regular inlet and outlet oil layout
Oil inlet, return oil, and venting threaded interfaces are arranged in different sections on the side and bottom of the pump body. The threaded interface has a stepped sealing structure, and with the sealing gasket, it can achieve high-pressure anti-leakage. The pipe routing layout is flexible, suitable for various machine oil circuit layouts.
Uniformly distributed multiple points of bolt locking seals, no oil leakage or accumulation at the shell joint
The upper and lower pump bodies and end covers are evenly pressed by multiple fastening bolts, and the internal is equipped with a high-temperature and oil-resistant composite sealing gasket. Under alternating high and low temperature conditions, the sealing components are less likely to harden and fail, and there is no oil leakage or accumulation at the pump body gap. Applicable scenarios
This product is designed to be compatible with four-cylinder small and medium-sized mechanical diesel power units, and is widely used in light freight trucks, wheeled loaders, agricultural tractors, mobile diesel generators, and is suitable for all-weather light and medium-load diesel equipment supply systems in fields, construction sites, and rural roads. It is applicable to diesel equipment without electronic control in all kinds of environments.
