The Causes Of Damage To Car Fuel Pumps
The maximum pumping pressure of the fuel pump depends on the standard of the pressure limiter. If the fuel pump pressure exceeds the predetermined pressure limit, the pressure limiter will open a bypass to allow the fuel to flow back to the inlet of the fuel pump. So, what is the reason for the damage to the fuel pump? Below, let me tell you!
The causes of damage to car fuel pumps
1. Insufficient fuel tank
When the fuel level warning light in the instrument panel lights up, there is approximately 7 liters of fuel remaining in the tank, and the fuel level in the tank is approximately at the red line. Due to the low oil level, the fuel pump motor cannot receive sufficient cooling and lubrication, which can cause the motor to overheat or even stall. If the oil pump is frequently in this working state, premature damage to the oil pump is inevitable.
2. Poor oil quality
Due to poor oil quality, the fuel tank is filled with various impurities or foreign objects. The fuel is sucked in through the filter at the bottom of the tank and pumped to the engine.
During this process, large particles of impurities are blocked by the filter, while small particles of impurities are sucked into the oil pump motor, which will inevitably exacerbate the wear of the oil pump motor and cause early damage to the oil chestnut.
3. The gasoline filter has not been replaced for a long time
The gasoline filter has not been replaced for a long time, and the fuel supply system of the gasoline filter is severely blocked. The gasoline pump is struggling to pump oil, and being under high load for a long time causes damage to the gasoline pump
Conclusion on causing damage to gasoline pump:
1. Gasoline has a cooling and lubricating effect on the oil pump. Failure to refuel in a timely manner after a fuel alarm can lead to a decrease in the cooling and lubrication effectiveness of the oil pump, resulting in damage;
2. Impurities in low-quality gasoline can cause blockages in the fuel supply system, leading to pump wear and damage (such as clogged filters). Early damage to fuel pumps is mostly caused by the use of inferior fuel in vehicles.
