During the long-term operation of the pump, due to wear and corrosion and other reasons, the original accuracy and performance have been lost. Regular inspections should be carried out. According to the actual situation, replace the vulnerable parts and basically restore their original performance. Mist Pump manufacturers share lift maintenance:
1. The front and rear bearing bushes of the connecting rod must not be installed incorrectly. The tightening torque of the connecting rod bolt is 120±5Nm. The screws should be tightened crosswise and locked with lock washers.
2. The newly purchased crankshaft must be ground and polished on the surface of each crank pin journal before assembly. The method is as follows: install the crankshaft on two equal-height V-shaped blocks and use the "No. 0" with a width of approximately 2/3 of the crankshaft length. "Iron sandpaper wraps the shaft journal in a full circle, and then wraps around the sandpaper with a rope of about 1 meter in length, pinching the end of the rope with both hands, tightening the rope and swinging the arms back and forth, pulling the natural color of the metal. , Repeat the above operation with metallographic sandpaper, until the surface is smooth and the nail is scratched without unevenness.
