Description

A diesel engine fuel injection nozzle cleaning and testing machine

Technical Field

The utility model provides a cleaning and testing machine, which relates to a cleaning and testing machine for a fuel injection nozzle of a diesel engine.

Background Art

Today's fuel injector is actually a simple solenoid valve. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the spray hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle at the head of the needle valve and the spray hole, forming a mist, which is conducive to complete combustion. The fuel injector will accumulate a lot of stains and oil during long-term work, so the fuel injector needs to be inspected and cleaned.

1. The utility model adopts a design that combines a lifting detection device, a rotating moving device and a cleaning device, and provides a machine for automatically cleaning and detecting diesel engine fuel injectors, which is beneficial to improving efficiency and reducing costs. The operator places the fuel injectors that need to be cleaned and tested in the placement holes on the placement table and fixes them. Then the lifter drives the lifting rod to extend and retract so that the detection device begins to descend to a certain height to cover the fuel injectors that need to be tested, and then the detection is carried out. After the detection is completed, the lifter drives the lifting rod to raise the detection device, and then the rotating motor starts to work to drive the rotating support column to rotate, and then the waste water tank rotates to rotate the placement table, and the next group of fuel injectors that need to be tested are rotated to the bottom of the detection device, and then the next group of fuel injectors that need to be tested are rotated to the bottom of the detection device, and then the next group of fuel injectors that need to be tested are rotated to the bottom of the detection device. Repeat the operation until all the injectors on the placement table have been inspected. Then the first servo motor starts working and drives the rotating screw to rotate. Because the rotating screw and the moving nut are threadedly connected, the position of the rotating screw is fixed. Therefore, when the rotating screw starts to rotate, the moving nut will move forward and backward, causing the placement table to move along the slide to the bottom of the cleaning device.
