The oil pump is broken, what is the big impact, what is the cause of the oil pump is broken

There are 3 common causes of fuel pump damage:

1.The fuel level warning light in the fuel tank oil is not sufficient because the fuel level is too low, and the fuel pump motor is not fully cooled and lubricated, which will cause the motor to overheat or even not work. In the long run, this will cause gasoline pump damage and speed up.

2.The quality of gasoline is too poor, there are impurities or foreign bodies in the gasoline, and the gasoline pump is too dirty, and these impurities enter the internal bearing of the gasoline pump, which will accelerate the wear of the bearing, resulting in damage to the gasoline pump.

3.The gasoline filter is not replaced for a long time, the gasoline filter is blocked, and the gasoline pump is in a high load state for a long time, resulting in damage to the gasoline pump.

The gasoline pump is broken, and there are two scenarios:

1. It is completely broken, that is to say, it cannot pump oil at all, and then the engine will turn off and cannot continue to work;

2. It is not completely broken, but the oil supply is insufficient or the oil supply pressure is low, then the engine will work poorly, such as poor acceleration, engine work shaking, engine work backfire, etc.

In addition, if the fuel supply pressure of the gasoline pump is too low, the engine will be flooded and cannot be started.

The oil pump is a lightweight and compact pump, and there are three major categories: in-line, dispensing, and monolithic. The oil pump needs a power source to operate, and the camshaft at the lower part of it is driven by the engine crankshaft gear.

The oil pump proposes an oil pump with an aluminum-containing material and a movable molded part arranged in the housing, wherein the movable molded part is at least partially made of a sinterable material containing at least one austenitic iron-based alloy, and the molded part made of a sinterable material has a coefficient of thermal expansion of at least 60% of the thermal expansion coefficient of the shell.

What causes the broken oil pump is as follows:1. The oil volume of the oil tank is insufficient, because the oil level is too low, the oil pump motor can not be cooled and lubricated, which will lead to overheating and even shutdown of the motor, if the oil pump is often in this working state, the premature damage of the oil pump is inevitable;

2. Poor oil quality, due to the relatively poor oil quality, the fuel tank will be filled with various impurities or foreign matter, and the fuel chestnut will suck the fuel through the bottom of the filter and pump it into the engine. In this process, the impurities of large particles are blocked by the filter, and the impurities of small particles are sucked into the oil pump motor, which will inevitably aggravate 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, the gasoline filter supply system is seriously blocked, the gasoline pump is hard, and the gasoline pump is damaged under long-term high load.

The reasons for the failure of the oil pump are: insufficient oil in the tank, poor oil quality, and the gasoline filter has not been replaced for a long time.

1. The fuel tank oil is not sufficient

When the fuel level warning light in the gauge is lit, there is about 7 liters of fuel left in the tank, and the fuel level in the tank is about the red line shown in the figure. Due to the low oil level, the fuel pump motor is not sufficiently cooled and lubricated, which will cause the motor to overheat or even stall. If the oil pump is constantly in this working condition, then premature damage to the oil pump is inevitable.

2. Poor oil quality

Due to the poor quality of the oil, the fuel tank will be filled with various impurities or foreign matter, and the fuel will be sucked in through the filter at the bottom of the fuel and pumped to the engine.

In this process, the impurities of large particles are blocked by the filter screen, and the impurities of small particles are sucked into the oil pump motor, which is bound to aggravate 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, the fuel supply system of the gasoline filter is seriously blocked, the gasoline pump is struggling, and the gasoline pump is damaged due to the long-term high load state.

What to do if the oil pump is broken

When the car oil pump is damaged, if the pump membrane is ruptured and the damage is not serious, you can apply soap to the damaged part, separate the damaged pump membrane from the intact pump membrane, stagger the damaged part, and then reinstall it. If the gap in the rupture is relatively long, you can use a film or tarpaulin to cut it into the shape of a round diaphragm and sandwich it between the diaphragm.
