1、 将Ⅰ~Ⅲ级气缸和Ⅱ级气缸互换，按照对应位置就位，气缸座和曲轴箱之

1. Interchange the Ⅰ~Ⅲ grade cylinders and the Ⅱ grade cylinders and put them in place according to the corresponding positions, with a few buckles on the connecting bolts between the cylinder block and the crankcase, do not tighten <br>them temporarily ; 2. Do not assemble the oil hanger for the time being during adjustment Seat and stuffing box; <br>3. Install the cylinder to be adjusted into the piston (guide ring and piston ring have been installed), and install the piston rod into the cross head (not to be locked), and then manually crank the piston into this stage The bottom dead center (the lowest point of up and down movement) and then lock the piston nut of this level; <br>4. Use a special measuring rod and feeler gauge to check the size of the piston rod to the inner wall of the stuffing box (Note: 4 points need to be symmetrically tested and recorded as Data 1, 2, 3, 4), combined with the data deviation to adjust the position of the cylinder block, so that the gap data in the corresponding direction is as consistent as possible; <br>5. Use a feeler gauge to check the uniformity of the clearance around the crosshead and the crosshead slide, and combine the data Deviation adjust the position of the cylinder block to make the gap data of the corresponding direction as consistent as possible; <br>6. Repeat the above steps No.4~No.5 to ensure that the data (data 1, 2, 3, 4 deviations are within the error range ) To determine the cylinder position.

1, the I-III-class cylinder and ii-class cylinder interchange, in accordance with the corresponding position in place, the cylinder seat and crankcase between the connecting bolts with a few buckles, do not tighten for the time being;<br>2, adjust temporarily do not assemble the oil holder and filler letter;<br>3, will need to adjust the cylinder into the piston (has been loaded into the guide ring and piston ring), and the piston rod into the cross head (temporarily do not lock), and then the manual disc car to make the stage piston into the lower dead point (the lowest point of up and down movement) and then lock the piston nut of that stage;<br>4, with a special measuring rod and stopper to check the size of the piston rod to the inner wall of the filler letter (Note: need to detect 4 points and recorded as data 1, 2, 3, 4), combined with the data deviation to adjust the position of the cylinder block, so that the corresponding direction of the gap data to achieve as consistent as possible;<br>5, with a stopper to check the cross head and cross head slide around the gap is uniform, combined with data deviation to adjust the position of the cylinder block, so that the corresponding direction of the gap data to achieve as consistent as possible;<br>6, the above steps No.4 to No.5 repeated, to ensure that the data (data 1, 2, 3, 4 deviation within the error range), determine the position of the cylinder.

1. Interchange the class I ~ III cylinders and class II cylinders, and put them in place according to the corresponding position. Fasten the connecting bolts between the cylinder base and the crankcase;<br>2. Do not assemble the oil hanger seat and stuffing box during adjustment;<br>3. Install the cylinder to be adjusted into the piston (the guide ring and piston ring have been installed), and install the piston rod into the crosshead (do not lock for the time being), then manually turn to make the piston of this stage enter the bottom dead center (the lowest point of up and down movement), and then lock the piston nut of this stage;<br>4. Check the dimension from piston rod to inner wall of stuffing box with special measuring rod and feeler gauge (Note: four points need to be detected symmetrically and recorded as data 1, 2, 3 and 4). Adjust the position of cylinder block according to data deviation to make the clearance data in corresponding direction as consistent as possible;<br>5. Check the clearance uniformity of crosshead and crosshead slideway with feeler gauge, and adjust the position of cylinder block according to data deviation to make the clearance data in corresponding direction as consistent as possible;<br>6. Repeat the above steps No.4 ~ No.5 to ensure the data (the deviation of data 1, 2, 3 and 4 is within the error range) and determine the cylinder position.<br>
