Maintenance of industrial equipment
To ensure the operability of the machine-building enterprise, maintenance of industrial equipment is carried out periodically. The service life of the machine or machine is limited, and to extend it, you need to monitor the technical condition, change consumables, perform complex repair work.
Equipment depends on the profile, capacity, level of technical training of enterprises. For each type of production, the repair and maintenance of industrial equipment, that is, the complex of works that ensure serviceability and operability, differ in terms of the timing and scope of work.
At machine-building enterprises, equipment is installed for the manufacture of parts and components, assembly of assemblies and products. For these purposes, machines and machines for metalworking, metalworking, welding are used, industrial robots, automated lines and CNC machines are used.
Military products are subject to increased requirements for manufacturing accuracy, reliability, and operating conditions. The enterprises of the aviation, space and other branches of the military-industrial complex are constantly upgrading equipment, a high degree of automation of production, requiring special qualifications. The peculiarity of metallurgical enterprises is the large dimensions of the units and increased loads during operation.
How to carry out maintenance of industrial equipment, the frequency and composition of work is determined by the enterprise itself, taking into account the requirements of the manufacturer’s documentation, GOST 18322-78 “System of maintenance and repair of equipment. Terms and definitions” and recommendations adopted for individual industries. For these purposes, a system of scheduled preventive maintenance is being developed.
According to the time of the maintenance of industrial equipment is divided into:
– Daily, including inspection and maintenance in cleanliness;
– Regulated, provided for in the passport of the unit and performed seasonally or during operation and consisting of oil change and fast-wearing parts, adjustment and verification of operation;
– Irregular, caused by deviations detected during the examination or when checking the indications of diagnostic systems.
The task of maintenance of industrial equipment is prevention and troubleshooting. Repair work is carried out when a breakdown is detected, according to the regulations or according to the technical condition of the equipment. The frequency of repair is calculated for various machines and aggregates. Metal-cutting machines are repaired every 8640 hours of operation, forging machines and machines with asynchronous motors 4320 hours, foundry electric furnace from 1440 to 2880 hours. At the same time, consumable and worn-out and out-of-order parts are replaced.
