How does Caterpillar 320B adjust the high idle speed?

Author:Lanye Wang Date:2021-1-12

  1. Carter 320B Adjustment governor, you can check high idle and low idle on the chassis. The low idle speed can be adjusted on the chassis, but the high idle speed can only be adjusted on the work (gōng zuò).
Carter excavator repair note:
Carter 320B high idle adjustment screw is sealed before leaving the factory, in order to prevent the change of high idle speed excavator repair on the imported excavator hydraulic system

Repairing the old car of the surface, system, and specific repairing excavator is to disassemble the car during repair

The next assembly, assembly and parts, all that can be repaired, are all replaced by the original car after repair. The structure and working principle of the pump, valve, motor, hydraulic cylinder and auxiliary components in the hydraulic system are introduced in detail, and

The disassembly and repair and installation methods of each component are described in detail. In each model, the electronic control system and fault diagnosis and elimination are also systematically introduced.

law. The high idle speed of different machines will vary with the additional load or the slight difference of the governor control spring (Spring). The load set point is critical. Attempts to adjust the high idle speed on the chassis will cause the idle speed to exceed the specification of the full load setting (Rotating speed), which is not allowed.
On some engines, the adjustment screws for high idle and full load set points are sealed at the factory to prevent the excavator repair from introducing the hydraulic system of the imported excavator.

Face, system, specific. The structure and working principle of the pump, valve, motor, hydraulic cylinder and auxiliary components in the hydraulic system are introduced in detail, and

law. When removing these seals, be careful not to damage the adjustment screws. Device.
  2. Carter 320B adjustment governor setting:
When the engine is running at full load, it will control the handle
(2) Placed at the Rotating speed position. The high idle speed is 1800 ± 10 rpm.
Adjustment screw
(1) Placed at a high idle position (position). Tighten the lock nut.
  3. Carter 320B engine speed (Rotating speed) measurement
The 9U-7400 Rotating speed table tool assembly can be measured by an electromagnetic pick-up sensor on the flywheel housing and a visual, engine Rotating component. )Engine speed.
The 6V-4950 speed pickup is another diagnostic tool accessory that can be used with the 9U-7401 multi-speed tachometer. The 6V-4950 speed pick-up can be used with 6mm (0.25 in) single-wall fuel oil tubes. With these tools, it is possible to quickly measure the engine speed with an accuracy of ±1 rpm.
