Fault 24: The water, ink uneven, when light or heavy one light one reason: 1 water, ink roller head serious wear, resulting in increased clearance, roller beat; 2 bearing lack of oil, dirty or damaged , leading to two different levels of severity.
Repair: 1 shaft head inlaid steel sleeve emergency steel jacket outside the park EDM strengthening treatment to increase the hardness and wear resistance; 2-axis metal brush plating or spray; 3 shaft head adhesion wear-resistant layer; 4 mapping processing; 5 Service or replace the bearings.
Failure 25: uniform, uniform ink roller does not turn Cause: The bearing is short of oil, dirty or damaged.
Repair: maintenance or replacement of bearings (A. According to West Germany DIN standard or similar national standard processing and purchase; B. use of domestic 203 bearings outside the park grinding repair emergency).
Fault 26: The pressure of the ink roller depends on the plate, and the pressure is not adjusted. Sometimes it is loose. The reasons are as follows: 1 The pressure regulating worm wheel and the worm shaft are worn or damaged, and the 2 roller bearing is dirty or damaged.
Repair: 1 survey and processing worm gear; 2 maintenance and replacement of bearings with the former.
Fault 27: The main gas pump has a lot of noise, and the amount of suction blows is small. Causes: 1 Dust plugs the air chamber; 2 Slips, cylinders, end caps, etc., are heavily worn, and the air leakage is not strict.
Repair: 1 Washing and inspecting the components; oil lubrication, 2 change seal gaskets, slide steel; 8 cover a small amount of grinding, see ping up;
4 repair cylinder.
Fault 28: The main air pump is seriously worn out and cannot be used. It is difficult to repair or lose economical repairs: 1 The original pump is used for surveying and processing outside the pipeline, and it is hoped that the professional air pump plant will produce it; 2 It is used in parallel with two Zhenjiang QB-80 air pumps. The connector can be slightly improved (the original pump air volume is 130 liters).
Fault 29: When the drive is running, the drive side hears a "click" sound Cause: The main drive multi-wedge belt is slipping or too loose, and the long belt part number 00.270.0051 short belt 00.270.0052.
Repair: 1 Open the hood, if it is too loose for the short belt, you can loosen the fastening bolts of the wheel axle seat through the bridge, fasten after tightening the belt, and tighten the belt tightly; 2 If the long belt is too loose, adjust the main Motor base.
Fault 30: The main drive multi-wedge belt is broken, and the part number is the same with 29 cases. Reasons: 1 normal fatigue pull off; 2 oil leakage erosion accelerated aging, elastic tight acceleration fracture.
Repair: 1 for import of new belt; 2 according to West Germany DIN standard processing; 3 to improve the original structure for the HTD belt drive, please refer to the failure of five; 4 to improve the original structure of the belt drive, reference failure 5.
Failure 31: Leakage of the water tank cover, part number 66.030.092F
Cause: Caused by long-term soaking of fountain solution.
Repair: 1 plastic glue adhesive seal; 2 mapping processing, molding processing is the most appropriate, choose bakelite or plastic turning can also be emergency.
Repair: 1 shaft head inlaid steel sleeve emergency steel jacket outside the park EDM strengthening treatment to increase the hardness and wear resistance; 2-axis metal brush plating or spray; 3 shaft head adhesion wear-resistant layer; 4 mapping processing; 5 Service or replace the bearings.
