Pompă de injecție de combustibil pentru excavator (101062-8520) pentru Caterpillar E312B – Q&O specificație de stil (engleză)
Î1: Care este identificarea produsului și domeniul de aplicare aplicabil al 101062-8520 pompa de injectie pentru E312B?
A1: The 101062-8520 pompa de injecție de combustibil este o componentă centrală a sistemului de alimentare cu piston de înaltă presiune compatibilă cu OEM, proiectat exclusiv pentru excavatoarele de dimensiuni medii Caterpillar E312B de 12 tone, paired with the Cat 3046T 4-cylinder diesel engine (puterea nominală: 70.1kW @ 1950 rpm).
Core Product Attributes: It is a mechanical-electronic integrated injection pump, featuring precise fuel metering and pressure regulation functions, and is fully interchangeable with the original E312B fuel system without additional modifications.
Applicable Scenarios:
Targets E312B’s typical working conditions: inginerie municipală, terasamente la scara mica, residential construction foundation digging, and orchard land preparation (funcționare continuă cu sarcină ușoară până la medie);
Serves as a direct replacement part for faulty original pumps (de ex., low fuel pressure, uneven fuel injection, pump plunger wear) and routine maintenance to restore engine power output and fuel efficiency.
Q2: Care este principiul de funcționare și funcțiile de bază ale 101062-8520 pompa de injectie de combustibil?
A2: Ca “fuel pressure core” of the E312B’s 3046T engine, cel 101062-8520 injection pump converts low-pressure fuel from the tank into high-pressure fuel for cylinder injection, realizing efficient combustion control via mechanical-electronic coordination:
Principiul de lucru
Low-Pressure Fuel Intake: The fuel transfer pump draws diesel from the tank and delivers it to the injection pump’s fuel chamber at a pressure of 0.3–0.5MPa;
High-Pressure Fuel Generation: Driven by the engine camshaft, the internal plunger reciprocates to compress fuel, generating a high pressure of up to 120MPa;
Precision Fuel Injection: The pump’s fuel metering valve adjusts the fuel injection quantity according to signals from the E312B’s ECM, and delivers high-pressure fuel to each cylinder’s injector at the optimal timing for complete combustion.
