Adjusting the oil quantity adjustment The oil pump is used to correct the speed and screw into the corrector part to make the rack correction stroke and/or the correction oil quantity meet the requirements. And adjust the correction spring preload to make it work at this speed. The adjustment of the idle oil quantity is the idle speed, and the idle speed limit screw is screwed to make the idle oil quantity meet the requirements. Then screw out the idle limit screw to reduce the position of the rack by 1mm (if there is a rack position parameter in the table, you can screw the idle limit screw directly to make the rack position 1mm smaller); then screw in the idle speed spring component to make The idle oil quantity meets the requirements.
After the oil pump is installed, if the diesel engine has an idling phenomenon, the component can be fine-tuned appropriately. Start oil adjustment The oil pump is the starting speed, measure the distance R from the end face of the pump body to the end face of the rack; adjust the elastic start to enrich the part so that the size M=R+(0.2~0.4). The elastic starting and thickening parts are mounted on the pump body, and the calibration and starting oil quantity should meet the requirements. Checking the parking conditions Under any working condition, turn the parking handle and the oil pump should be able to stop the oil. There is no counter oil supply.
