冷库压缩机如何计划检修，下面小编为您讲解一下：
Cold storage compressor how to plan maintenance, the following small series for you to explain:
1.机器大修或中修时间确定，应根据生产情况和机器的运转时间来确定。冷库有淡旺季，一般大、中修都要在生产淡季进行。春季大修，秋季中修，运转700小时左右进行小修。因此，机器检修要与生产紧密配合，不要墨守成规，以检修不误生产来制定计划为宜。
1 machine repair or repair time to determine, should be based on the production situation and the running time of the machine to determine. Cold storage has a short season, the general large, medium repair should be carried out in the production of low season. The spring autumn overhaul, repair, running 700 hours to repair.Therefore, the machine to work closely with the production and maintenance, don't in to check the correct production plan.
2.机器在小修时，发现曲铀箱底部有较多的金属粉沫，就应该查明造成金同粉沫的原因。要查明原因，就应该拆卸检查油塞与汽缸、轴须与轴承之间的磨损情况。这样就应按中修的内容进行检修，否则达不到检修的目的。机器在大修时，经拆卸大部分零部件检查，从机件的装配间隙和磨损情况看，符合规定的技术要求，对于较难拆卸的机件(如曲轴)，不拆卸为宜。这样可缩短检修时间，使机器尽快投入生产；同时也可避免因装配时不注意，使机器的原有装配间隙或几何尺寸有所变化，而影响机器的检修质量。
2 machines in repair, metal powder has more Youxiang curved bottom, it should find out the cause of the same gold powder. To find out the reasons, it should be removed to check the oil plug and cylinder, shaft and bearing wear. This should be carried out according to the contents of the overhaul, otherwise not up to the purpose of maintenance. The machine in the overhaul, the demolition of parts inspection, assembly clearance and wear parts from the situation, meet the technical requirements for parts, difficult disassembly (such as crankshaft), without disassembly is appropriate. This can shorten the maintenance time, so that the machine can be put into production as soon as possible, but also to avoid the attention of the assembly, so that the original assembly clearance or geometric size of the machine has changed, and affect the quality of machine maintenance.
3.在检查测量机件时，—般依测量运动机件的装配间隙为主。当机件的装配间隙超过规定要求范围时，再检查有关零件的磨损量。若测量工具不全，有些机件磨损虽然超过规定要求，但可根据机件材料表面硬度的大小来确定修理或更换的部件。例如曲柄销与连杆大头瓦之间的磨损，其间隙超过规定要求，一般是用更换大头瓦的方法来修复。因为轴瓦的硬度比曲柄销的表面硬度小的多，所以易于磨损。
3 check the measurement parts, according to the general assembly of the main moving parts clearance measurement. When parts of the assembly clearance exceeds the specified requirements range, and then check the wear of the parts. If the measurement tool is not complete, although some parts wear more than requirements, but to determine the repair or replacement of parts according to the size of the material surface hardness machine. For example, the wear between the crank pin and the connecting rod big end tile, the gap exceeds the specified requirement, and is generally used to replace the bulk tile method to repair. Because of the hardness of the crank pin bearing than the surface hardness of small, so easy to wear.
若机件发生偏磨现象。如活塞与汽缸偏磨，必须检查连杆大、小头孔之间的平行度和扭摆度和活塞销的中心线与活塞中心线的平行度等几何尺寸精度的测量，查找原因，加以消除。否则，发现问题，不检查处理，这就是检修人员的失职。
If the phenomenon of partial wear parts. As the eccentric wear of the piston and the cylinder, the connecting rod must be checked, the small hole between parallelism and twist degree and the piston pin of the center line and the central line of the piston parallel degree of geometric accuracy of measurement, to find the reasons and to eliminate them. Otherwise, found that the problem is not checked, this is the failure of maintenance personnel.
4.对于更换机件或修理机件的一般要考虑其可靠性，又要考虑经济性。对于磨损超过规定范围的机件，主要考虑到可靠性，该修理或更换的机件，必须认真掌握，不能马虎从事，不然的话，因小的机件损坏造成大的机件损坏，使整个机器损坏过重，不但使机器的检修任务增加，而且也使机器的寿命缩短。对于能修理的军件，不要过早的更换新的机件，这样可以减少校修费用。在整个修理过程中应注意这一问题。
4 parts for replacement or repair parts of the general should consider the reliability, but also consider the economy. To wear over the scope of the provisions of the parts, mainly considering the reliability of the parts, repair or replacement, must grasp, not engaged in sloppy, otherwise, because of the small mechanical damage caused by mechanical damage, the damage to the machine is too heavy, not only makes the machine maintenance task increases, but also enable the machine to shorten the life of. The army can repair, replace not premature new parts, it can reduce the repair cost of school. This problem should be paid attention to during the whole repair process.
