制冷系统常用的往复活塞式制冷压缩机,在轴颈、连杆大、小头轴瓦或轴衬,气缸与活塞(或活塞环)等多处运动零部件处构成摩擦付。为了保障这些运动部件处于正常工作状态,在压缩机运转时,必须使摩擦面经常保持油膜,尤其在压缩机转速均已普遍提高的情况下,瞬时断油就会引起严重的后果,以下列举几个因管理疏忽使用不当,使压缩机断油而影响工作的例子。 Refrigeration system commonly used reciprocating piston refrigeration compressors, in the journal, connecting rod, small head bush or bushings, cylinder and piston (or piston ring) and other moving parts constitute friction pay. In order to ensure that these moving parts are in normal working condition, the oil film must be kept on the friction surface constantly when the compressor is operating. Especially when the compressor speed has been generally increased, the instantaneous oil cut-off will cause serious consequences. An example of improper use due to management negligence, the compressor off the oil and affect the work of the example.
