1. Regular maintenance is the main form of preventive maintenance: the previous regular maintenance increased the maintenance workload, maintenance costs and downtime of the light steel keel machine. As a result, many invalid repairs were done, but the light Random failures and early failures of the steel keel machine, and excessive disassembly and repair of the keel machine are prone to artificial failure, increase maintenance consumption, and reduce maintenance efficiency;

2. Reliability as the maintenance method: The reliability-based maintenance method is also the inheritance and development of the traditional prevention-based maintenance method, which can control the failure rate of the light steel keel machine to maintain its inherent reliability. .
