离心式制冷压缩机的常见问题有哪些

离心式制冷压缩机的常见问题有哪些

发布日期:2018-04-09 作者:地源热泵 点击:

空气调节制冷系统的迅猛发展,迫切需要大型及低温冷库制冷压缩机,而离心式制冷压缩机以它自身的优点,很好的迎合了这种需求。

With the rapid development of air conditioning refrigeration system, large and low temperature cold storage compressors are urgently needed, and centrifugal refrigeration compressors are well suited to this demand with its own advantages.

主要优点:

Major advantages:

1、制冷能力大,而且大型离心压缩机的效率接近现代大型立式活塞式压缩机。

1, refrigeration capacity is large, and the efficiency of large-scale centrifugal compressor close to modern large vertical piston compressor.


2、结构紧凑,质量轻,比同等制冷能力的活塞式压缩机轻80% ~ 88%,占地面积可以减少一半左右。

2, compact structure, light weight, compared with the same refrigeration capacity of piston compressor light 80% ~ 88%, covering area can be reduced by about half.

3、没有磨损部件,运行平稳,振动小,噪声小。

3, no wear parts, stable operation, small vibration, small noise.

4、能够经济的进行无级调节。当采用进气口导叶阀时,可使机组的负荷在30% ~ 100%范围内进行高效率地能量调节。基于以上优点,离心式压缩机在短短地时间得到广泛地应用和发展。但是如果不解决好离心式压缩机在运行中发生的问题,不仅使机器效率大为降低,严重地可能会毁坏机器。

4. Stepless regulation can be carried out economically. When the intake vane valve is adopted, the unit load can be regulated efficiently in the range of 30% to 100%. Based on the above advantages, centrifugal compressor has been widely used and developed in a short time. However, if the problems in the operation of the centrifugal compressor are not solved, not only will the efficiency of the machine be greatly reduced, but also the machine will be seriously damaged.

解决措施:

Solving measures:

要求压缩机的制冷量减少到喘振点以下时,从压缩机出口引出一部分气态制冷剂,不经冷凝直接旁流至压缩机吸气管。这样,既可减少通入蒸发器的制冷剂流量,以减少该制冷系统的制冷量,又不致使压缩机的排气量过小,从而可以防止喘振发生。

When the refrigerating capacity of the compressor is reduced to below the surge point, a part of gaseous refrigerant is drawn from the outlet of the compressor, which flows directly to the suction pipe of the compressor without condensation. In this way, the refrigerant flow through the evaporator can be reduced, so as to reduce the refrigerating capacity of the refrigerating system, and not to cause the exhaust of the compressor to be too small, so as to prevent the surge from happening.
