What is the function of throttle motor?

The throttle motor is a component that controls the accelerator and speed of the motor vehicle. When the engine is idling, it is called idle speed. When idling, according to the engine temperature and load, change the cross-sectional area of the idling air passage, so that the engine has the best idling speed under different conditions.

Why choose a good quality throttle motor?

The quality of the throttle motor of the excavator depends on the positioner and the electronic parts inside. If the locator is not good, the throttle will go up and down. If the electronic parts are not good, it will work unstable and affect the efficiency of use. The products of some manufacturers are low in price but the quality is not good, and there will be problems after 2 months.

How to deal with the failure of the excavator throttle motor?

1. The most easily damaged part of the excavator is also the throttle motor. Usually, the failure phenomenon is that the accelerator cannot be added, the accelerator cannot be turned off, or the fuel addition and subtraction stroke is incorrect.

2. If the throttle can't be added up, you can first test whether the 24V voltage of the 1st and 2nd feet of the throttle motor is normal. If it is normal, remove the motor assembly and measure the internal small motor to see if it is normal. When the small motor is idling with 24V voltage, the current is 120 milliseconds. If the difference is too far, it may be damaged, and you must check the throttle cable. If it is normal, replace the throttle control template.

3. The pressure switch is also more easily damaged in the excavator. The main problem caused by the pressure switch is the failure of the automatic throttle. The three pressure switches will be turned on when they are in action.

How to deal with the phenomenon that the excavator throttle motor cannot be turned off?

Throttle motorfails to turn off. When testing the fault, you can first increase the throttle to the tenth gear and run at the highest speed, and then suddenly turn off the key. If the throttle motor still stays at the highest speed position, then measure the yellow wire on the throttle motor plug first. The normal voltage is at When the key is turned off, the voltage is zero. If the voltage of the key off is maintained at 24V, it may be due to damage to the delay relay. If the voltage of the key off can return to zero volts or the ignition cannot be turned off, it proves that the template of the throttle assembly has been damaged. There is a phenomenon that when the throttle stroke of the key is turned off, it will run to idle speed or other positions. Generally, it is necessary to adjust the stroke or replace the throttle cable.
