Where is the fuel pump mounted? Where is the car s oil pump located? How to dismantle?

The pump is divided into gasoline pump and oil pump, the gasoline pump is installed in the fuel tank, and the gasoline pump is installed in the engine.

The role of the gasoline pump is to suck the gasoline out of the tank and pressure it through the line and the gasoline filter into the float chamber of the carburetor. It is thanks to the petrol pump that the petrol tank can be placed in the rear of the car, away from the engine, and below the engine.

How the Gasoline Pump Works:

At present, most models of fuel pumps are installed in the fuel tank of automobiles, driven by electric power The fuel pump is composed of three parts: pump body, permanent magnet motor and shell. The permanent magnet motor is energized to drive the pump body to rotate, suck the fuel from the oil inlet, flow through the inside of the electric fuel pump, and then press out from the oil outlet to supply the fuel system. The fuel flows through the inside of the electric fuel pump and cools the armature of the permanent magnet motor, also known as the wet fuel pump.

The electric motor part of an electric fuel pump, consisting of a permanent magnet fixed to the housing and an armature that generates electromagnetic torque, as well as a brush device mounted on the housing. The brushes are in contact with the commutator on the armature, and their leads are connected to the posts on the housing, directing the voltage to control the electric fuel pump to the armature windings. The two ends of the electric fuel pump's casing are crimped and riveted so that the parts are assembled into a non-detachable assembly.

Hello, the fuel pump is all in the car fuel tank, and the fuel tank is located in the rear seat of the car, or under the trunk. The main fuel pump.

The role is to supply fuel to the engine. The fuel pump delivers high-pressure fuel to the distribution pipe to ensure continuous delivery to the injector.

Fuel, the fuel pump is composed of an electric motor, a pressure limiter, and an inspection valve, and the electric motor actually works in the oil pump casing.

, don't worry because there is nothing inside the shell that can ignite, and the fuel can lubricate and cool the fuel.

Motor, check valve at the oil outlet, pressure limiter located on the pressure side of the oil pump casing, with a passage to the oil inlet.

Road. Hope it helps, hope.

The oil pump is divided into a gasoline pump and an oil pump, the gasoline pump is in the fuel tank, and the oil pump is installed in the engine.

How to remove the car fuel pump.

1. Release the residual pressure in the fuel pipeline and disconnect the negative cable of the battery.

2. The fuel pump maintenance hole is located in the trunk, open the trunk lid and remove the bottom plate pad; When the fuel pump service hole is located in the rear seats, flip the rear seat cushion to expose the service hole.

3. Use a slotted screw screw to gently remove the fuel pump plugging cover from the edge.

4. Detach the electrical plug of the fuel pump, press and hold the buckle button, and disconnect the quick plug of the oil supply and return pipe.

5. Use the fuel tank lock ring wrench (general maintenance tool) to disassemble the lock ring.

6. Release the fixing buckle, and then take out the fuel level sensor unit, fuel filter, and fuel pump assembly.

Reasons for insufficient pressure in the gasoline pump:

1. The oil seal at the rear end of the oil pump drive gear shaft is worn or the pipeline joint is not strict, and there is air in the pipeline; The oil tank is short of oil and the filter is dirty;

2. The main bearing at the end of the oil pump gear is worn or stuck, which makes the axial clearance of the oil pump gear too large;

3. The needle roller bearing is damaged, so that the gear meshing of the oil pump is abnormal, and the inner cavity of the oil pump housing is strained;

4. The oil pump regulating valve or safety valve is stuck, and the spring elasticity is insufficient or broken.

The oil pump is generally installed on the basis of buried anchor bolts, and between the base and the foundation, pairs of wedge pads are used for correction.

Correct the concentricity of the pump shaft and the motor shaft, and the allowable deviation is millimeters on the outer circle of the coupling road; The gap between the planes of the two couplings should be 2 4 mm, and the gap should be held evenly with a tolerance of millimeters.

After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling and check the concentricity of the shaft again.

After 2 to 3 hours of actual trial operation of the unit, the final inspection is carried out, and if there is no bad phenomenon, the installation is considered qualified. Check the temperature and vibration of the bearings during commissioning.

During installation, in order to prevent debris from falling into the machine, all the eyelets of the unit should be covered.

At present, most models of fuel pump are installed in the fuel tank of the car, driven by electricity, and the fuel pump is composed of three parts: pump body, permanent magnet motor and shell.

Fuel pump failure detection safety blind guess precautions:

1. Old fuel pump: This kind of fuel pump cannot be dry tested when troubleshooting the fuel pump of a vehicle that has been used for a long time. Because when the fuel pump is removed, because there is fuel left in the pump casing, once the brush is in poor contact with the commutator during the power-on test, a spark will be generated to ignite the fuel in the pump casing, and the consequences are very serious.

2. New fuel pump: The newly replaced fuel pump shall not be dry tested. Because the oil pump motor is sealed in the pump casing, the heat generated by the power cannot be dissipated during the dry test, and the armature will burn the motor once it is overheated, so the fuel pump must be soaked in fuel for testing.

3. Other aspects: After the fuel pump leaves the fuel tank, the oil pump should be wiped clean in time, and sparks should be avoided near its placement, and the safety principle of "wiring first, then energizing" should be followed.

Summary. Hello, happy to answer for you.

1. The oil pump bracket base should be firm, rigid, and fully absorb vibration.

2. The coaxiality of the pump and motor shaft should be controlled, the maximum angle error should be less than 10, and the flexible coupling should be used as much as possible to avoid any stress caused by bending or radial force.

3. The diameter of the suction pipe of the oil pump should not be less than the diameter of the pump outlet, and the oil flow of the oil suction filter should not be less than twice the flow rate of the oil pump.

4. The suction pressure of the pump suction inlet is to.

5. Note that the oil suction joint and the entire oil suction pipeline must be strictly sealed to avoid air leakage, otherwise it will cause noise and system vibration.

6. The oil drain pipe must be directly matched to the oil surface of the oil tank, and the back pressure generated by the piping should be maintained at the following.

Note: When the pump is connected with the coupling or motor, the shaft and key should be freely matched, otherwise it cannot be forcibly installed, so as not to cause damage to the oil pump.

Hope it helps you and I wish you happiness and happiness every day! 
