preventKKEarly module damage and attention to routine maintenance and repair are the key to ensure its long-term stable operation。The following are some specific measures and suggestions：

one、Correct installation and commissioning

1. Install the linear guide rails：When installing a linear slide，The moving surface of the shaft and linear slide shall be coated with the specified grade of cleaning oil，To reduce friction and wear。

2. Check before initial start-up：After the engine linear slide is installed，The fuel switch should be turned off before initial start-up，Idling the engine with the starter several times，To check whether the components are working properly。When the engine oil pressure gauge shows，reconnection、Turn on fuel switch，And put the throttle in the medium-low position，Start the engine for running observation。The idle running time cannot exceed5minutes。

two、Use and maintenance during running-in period

1. Run in period：Do a good job in the running-in period of the new engine and the engine after overhaul，In the running-in period, it is forbidden to work for a long time under the condition of rapid load reduction and high-speed。This can reduce the failure caused by the lack of tight fit between parts。

2. Shutdown processing：After a long period of full load on the engine，Cant shut down immediately，The engine must be run at medium to low speed with no load15It wont stop for another minute。This ensures that the heat inside the engine is fully dissipated，Avoid overheating damage。

three、Regular inspection and maintenance

1. Oil ferrography analysis：Regular oil ferrography analysis，Early detection of abnormal wear based on analysis results，Accurately determine the composition and possible location of abrasive particles，To nip it in the bud，Avoid serious accidents such as rolling tile and burning shaft。

2. Measurement and adjustment：Strictly measure the coaxiality and roundness of the main line slide hole of the diesel engine block，Ensure the diesel engine body coaxial dimension is more accurate。At the same time, the runout of the crankshaft is measured，The thickness of the bearing is selected，Make the oil moistening gap in each axial position to achieve consistency。

3. Maintenance and assembly quality：Improve the repair and assembly quality of linear slides，Strictly control the passing rate of connecting rod on board。Ensure that the back of the linear slide is smooth and spotless，The positioning convex point is intact；new、The parallelism and distortion of the old connecting rod should be measured，The unqualified connecting rod is prohibited from boarding。

four、Lubrication and cleaning

1. Lubrication maintenance：The lubricating oil should be filled before the first use，Do not mix oil types。Under normal use，A certain distance is recommended for each walk（Such as100km）The operation should be checked once，decontamination，relube。The slide rail and screw and other parts should be kept in good lubrication state。

2. Environmental control：In the case of poor working environment，Care should be taken to avoid placing the module in a humid or hot place。meanwhile，Hard particulate protection（sandiness、Scrap iron）enterKKModule rail inside，Avoid wear on guide rail and ball screw。

five、Professional training and operational specifications

1. Professional training：Conduct professional training for operators，Make it clearKKPerformance characteristics of the module、Operating procedures and maintenance knowledge。This improves the skill level of the operator，Reduce the failure caused by improper operation。

2. Operating specification：Develop and strictly implement operating procedures，Ensure that operators are operating according to specifications。Any abnormal situation should be reported and handled in time，Avoid exacerbating the problem。

To sum up，preventKKEarly module damage and pay attention to daily maintenance and repair need to start from many aspects，Including proper installation and commissioning、Use and maintenance during running-in period、Regular inspection and maintenance、Lubrication and cleaning as well as professional training and operational specifications。Its the only way to be sureKKThe module runs stably for a long time and exerts its maximum efficiency。
