The routine maintenance of printing equipmentThe routine maintenance of printing equipment
Well as routine maintenance of printing equipment, it may significantly reduce equipment failures, improve equipment utilization, extending equipment life.Good equipment can make book printing / catalog printing/magazine printing/brochure and so on printing with hight quality. Under normal circumstances, the routine maintenance of printing equipment, mainly the following points.
Focus on maintenance work
Printing equipment maintenance mechanical maintenance and electrical maintenance is divided into two aspects. In mechanical maintenance, with particular attention to oil, grease the proper use of. Some of the description specified in printing equipment, equipment only requires lubrication with 32, 46, machine oil, but in actual use has found that a lot of impurities, while the operator has little oil filter cleaning habits. In response to this situation, it is recommended the use of No. 32 turbine oil in winter and summer use of 46 turbine oil. Because the turbine oil, machine oil is relatively speaking, fewer impurities. As for the exposed chain, sprocket, and guide surface 68, such as lubricating oil can be used.
For example: a straight-line package type JBB40 this machine, because the rubber wheel bearing grease bearings Department Shi stuck a result of bearing failure, disassemble sprocket, bearing in the bearing, insert the temperature of the sodium base grease, the rubber tire recovery functioning; a QZ104 hydraulic cutter hydraulic systems use 32, 46, mechanical oil, due to impurities in the oil filled inlet filter, resulting in hydraulic system in the noise and filter cleaning time after troubleshooting.
In electrical maintenance, in particular, observe the motor noise, if unusual sound, should be promptly cut off the power supply, reported to maintenance personnel. In addition, attention should be paid printing equipment sensor cleaning, to avoid the scraps of paper, ink, oil, etc. fall into the sensor surface caused by mechanical failures. For example: a SORD Heidelberg presses in the printing newsprint, the emergence of self-protection state of the machine, after examination found the former rules because of scraps of paper covered the first result of photoelectric detectors.
Good maintenance records
Each machine is equipped with a maintenance record book, the equipment failure time, the phenomenon of position, to exclude methods, the exchange parts, put on record after the operation condition, etc., establish the maintenance files for future reference.
Vulnerable parts of supply thereafter,
To reduce the printing equipment repair parts during the waiting time. Should therefore be vulnerable pieces of equipment supply thereafter. Each device that some components are particularly vulnerable to wear and tear, such as magnetic switches, lost control of paper machine at lifting Taiwan trip switch, turn bad clutch controller circuit board, DC power rectifier bridge, counting photoelectric sensor receiving / launching the first Dengjun wearing parts for the electrical.
Accumulate experience in practice
Malfunctioning of the equipment when the first time can be cut off the power supply is the operator. Operating personnel should be diligent observation, care of equipment, so that failure to prevent further expansion, while equipment failure occurs, the operator provided conditions are favorable technical staff accurately and timely troubleshooting. For example: in determining whether there is electrical failure, the operator must identify the capacity of electrical noise is normal for the benefit of motor maintenance.
In addition, for some equipment, and technology may be based on a reflection of the operator on the operation of printing equipment in some inconvenience to the local to be improved. For example: a folding machine off, the original mechanical and electrical path is not set jog button, and improved jog added features that make a lot of easy to operate.
