Screw in the screw tooth bar stroke increase and vice versa


Swinging speed control handle and parking handle, the gear bar should be flexible and free from blockage and card issuance. The full stroke of the gear bar should not be less than 21mm. The idle speed limit screw and the idle speed spring component can be assembled during the debugging process. Adjustment test debugging can be carried out as follows. The distribution of the rack stroke, the rack stroke table is installed, and the rack is zero. The rack stroke should be within the specified range. The oil pump is 20r/min below the rated speed, and the high-speed limit screw is adjusted to make the governor not work. Adjust the total oil limit screw so that the rack stroke is 1~2mm larger than the specified range of the calibration; The speed of the flying block is full, the parking limit screw is adjusted, and the anti-corrosion wear-resistant abrasive pump makes the rack stroke within the specified range.
The adjustment of the high-speed working condition of the oil pump is the rated speed, and the high-speed limit screw is adjusted so that the governor does not work, and the rack stroke should be within the specified range. If not in the specification, the total oil limit screw should be adjusted. The screw-toothed screw stroke increases, otherwise it decreases. The adjustment oil pump of the control sleeve is the rated speed, and the oil pump control sleeve is adjusted to make the oil quantity and the oil quantity difference of any two cylinders within the specified range.
Correction condition adjustment The oil pump is lower than the correction active speed, adjust the corrector parts to make the rack stroke meet the requirements; the oil pump is the correction end point speed, the rack stroke should be within the specified range, if not within the specification, the correction spring should be adjusted Pre-tightening force or replacement of the correction spring; in the specified correction speed, the oil quantity and the difference between the oil quantity of any two cylinders should be within the specified range. If it is not within the specification, the corrector stroke should be changed by adjusting the corrector part.
