Fault diagnosis of automobile fuel pump


Electric fuel pump quality judgment:

After the electric fuel pump is damaged, the noise is obviously increased compared with the normal time, and can be judged by listening to the sound.

The resistance of the armature winding resistance of the electric fuel pump is generally around 10-20Ω. If the resistance is too large or too small, it indicates that there is a short circuit in the armature winding of the electric fuel pump, the brush is in poor contact, or the winding is broken or broken. .

Check the electric fuel pump's oil delivery: Remove the electric fuel pump's oil outlet pipe, connect the electric fuel pump's terminal to a voltage higher than 11.5V, and collect the fuel from the oil outlet with the measuring cup. The oil amount within 30 seconds should be not Less than 0.6 liters, otherwise the pump body is a defective safety valve.

The electric fuel pump is a non-repairable part that must be replaced when it is determined to be damaged.

Vacuum worktable fitted with aluminum alloy bars and suction cups is rigid yet flexible for various configurations. Cropping the full sheet to your ideal size, routing, drilling, sawing, cutting, and milling-multiple functions, all in one.

Features:
Separate heads:

Some wood routers have multiple separate heads that can come down simultaneously or not. Some routers have multiple heads that can run complete separate programs on separate tables all while being controlled by the same interface.


Dust collection / Vacuum Collector:
The wood router typically has 6"-10" air ducts to suck up the wood chips/dust created. They can be piped to a stand-alone or full shop dust collection system.

Some wood routers are specialized for cabinetry and have many drills that can be programmed to come down separately or together. The drills are generally spaced 32 mm apart on centres - a spacing system called 32 mm System. This is for the proper spacing of shelving for cabinets. Drilling can be vertical or horizontal (in the Y or X axis from either side/end of the workpiece) which allows a panel to be drilled on all four edges as well as the top surface. Many of these machines with large drilling arrays are derived from CNC point-to-point borers.
