一、概况机械维修一般有两种方法:损坏后修理和预防修理。工业发达国家均以预防性修理为主。预防性维修有两个主要体系:一是苏联的P制(即计划预期检修制);二是美国的PM制(预防维修)和日本的TPM制(全员生产维修制)。我国自五十年代以来,一直沿用苏联的计划预期检修制(亦称强制保养制)。这种制度五十年代和六十年代在我国曾起过积极作用。但20多年的实践证明,计划预期检修制确实存很多弊病。它的先决条件是要有准确的台时记录。
I. INTRODUCTION Mechanical maintenance generally has two methods: repair after damage and preventive repair. The industrialized countries all rely on preventive repairs. Preventive maintenance has two main systems: First, the Soviet Union’s P system (ie, planned anticipatory maintenance system); Second, the United States’s PM system (preventive maintenance) and Japan’s TPM system (full production maintenance system). Since the 1950s, our country has been using the Soviet Union’s planned anticipatory maintenance system (also known as the mandatory maintenance system). This kind of system had played an active role in our country in the 1950s and 1960s. However, more than 20 years of practice has proved that the plan is expected to have many drawbacks. Its precondition is to have an accurate time record.
