EXPLANATION TO SOME TERMS

To the term " Maintenance»

Maintenance contains operations regulated in the design documentation to maintain the performance or serviceability of the product during its service life.

The floor of the maintenance operation in accordance with GOST 3.1109 is understood as the complete part of the maintenance of a component part of the product, performed at one workplace by a performer of a certain specialty.

Transportation is understood as the operation of moving cargo along a certain route from the place of loading to the place of unloading or reloading. The transportation of self-propelled products does not include their movement under their own power.

By waiting, they understand that the product is in a state of readiness for its intended use.

Maintenance may include washing the product, monitoring its technical condition, cleaning, lubricating, fastening bolted connections, replacing some component parts products (e.g. filter elements), adjustments, etc.

To the term "repair"

The repair operation in accordance with GOST 3.1109 is understood as the completed part of the repair, performed at one workplace by performers of a certain specialty.

Repairs may include disassembly, troubleshooting, monitoring the technical condition of the product, restoring parts, assembling, etc. The content of some of the repair operations may coincide with the content of some maintenance operations.

Repair of products can be carried out by replacing or restoring individual parts and assembly units.

Repair of any kind, as a rule, should be accompanied by the issuance of certain guarantees for the subsequent life or operating time of the product.

To the term "System of technical maintenance and repair of equipment"

In a particular case, the system of technical maintenance and repair of equipment may include materials, blanks, spare parts, etc., that is, it is characterized by material and technical support, which can be defined as the ability of the service organization to provide the necessary resources for maintenance. and repair of an object under a given strategy and under given conditions. The specified conditions apply both to the object itself and to the conditions of its operation, maintenance and repair.

To the terms "Maintenance cycle" and "Repair cycle"

In a particular case, the starting point of the maintenance cycle (repair cycle) can be the beginning of the use of the product.

To the term "Periodic maintenance"

Periodic maintenance may differ in the content of operations. In this case, maintenance services are numbered in ascending order, for example, shift maintenance, TO-1, TO-2, TO-3, etc.

To the term "Seasonal maintenance"

Seasonal maintenance includes the operations of replacing seasonal grades of operating materials with flushing of the corresponding systems, installation and removal of insulation and engine preheating devices, etc.

Seasonal maintenance is only performed on products used in the same significant changes the state of the environment throughout the year.

To the term "Scheduled Maintenance"

Maintenance schedules can be tight and tolerant. The type of regulation should be established in the operational documentation.

To the term "Method of maintenance by specialized personnel"

Maintenance personnel can be specialized in object types, object brands, forks of operations, and forks for maintenance.

To the terms "Overhaul", "Medium repair", "Current repair"

Major, medium and current repairs can be planned and unplanned. The basic part is understood as the main part of the product, intended for its layout and installation of other component parts.

To the term "Unscheduled repair"

Unscheduled repairs are carried out in order to eliminate the consequences of failures or incidents.

To the term "Aggregate repair"

The opposite of the aggregate method is the detailed method, in which individual parts that have failed are replaced or restored.

To the indicators of the maintenance and repair system

The indicators of the maintenance and repair system allow us to estimate the cost of time, labor and funds for maintenance and repairs and contain the costs due to the design and technical condition of the product (operating costs), and the costs due to the organization, technology for performing maintenance and repairs, material and technical provision, personnel qualifications, environmental conditions, etc.

Indicators of the maintenance and repair system pp. -65 estimate the total cost of time, labor and funds for maintenance and repairs and contain costs due to the design and technical condition of the product (operating costs), and costs due to the organization, technology for performing maintenance and repairs, logistics, personnel qualifications , environmental conditions, etc.

The calculation of the indicators of the system of maintenance and repair of equipment is similar to the calculation of the corresponding indicators of maintainability in accordance with GOST 21623. In this case, instead of operating costs, the total costs of time, labor and funds are taken into account.

EXPLANATION TO SOME TERMS

To the term "Maintenance"

Maintenance contains operations regulated in the design documentation to maintain the operability or serviceability of the product during its service life.

Transportation is understood as the operation of moving cargo along a specific route from the place of loading to the place of unloading or reloading. The transportation of self-propelled products does not include their movement under their own power.

By waiting, they understand that the product is in a state of readiness for its intended use.

Maintenance may include washing the product, monitoring its technical condition, cleaning, lubricating, fastening bolted joints, replacing some component parts of the product (for example, filter elements), adjusting, etc.

To the term "repair"

The repair operation in accordance with GOST 3.1109 is understood as the completed part of the repair, performed at one workplace by performers of a certain specialty.

The repair may include disassembly, troubleshooting, control of the technical condition of the product, restoration of parts, assembly, etc. The content of some of the repair operations may coincide with the content of some maintenance operations.

Repair of products can be carried out by replacing or restoring individual parts and assembly units.

Repair of any kind, as a rule, must be accompanied by the issuance of certain guarantees for the subsequent period of operation or operating time of the product.

To the term "System of technical maintenance and repair of equipment"

In a particular case, the system of technical maintenance and repair of equipment may include materials, blanks, spare parts, etc., that is, it is characterized by logistics, which can be defined as the ability of the service organization to provide the necessary resources for maintenance repair of the object according to the specified strategy and in the specified conditions. The specified conditions apply both to the object itself and to the conditions of its operation, maintenance and repair.

To the terms "Maintenance cycle" and "Repair cycle"

In a particular case, the starting point of the maintenance cycle (repair cycle) can be the beginning of the use of the product.

To the term "Periodic maintenance"

Periodic maintenance may differ in the content of operations. In this case, maintenance services are numbered in ascending order, for example, shift maintenance, TO-1, TO-2, TO-3, etc.

To the term "Seasonal maintenance"

Seasonal maintenance is carried out only for products that are used due to significant changes in the environment during the year.

To the term "Scheduled Maintenance"

Maintenance schedules can be tight and tolerant. The type of regulation should be established in the operational documentation.

To the term "Method of maintenance by specialized personnel"

Maintenance personnel can be specialized in object types, object brands, forks of operations, and forks for maintenance.

To the terms "Overhaul", "Medium repair", "Current repair"

Major, medium and current repairs can be planned and unplanned. The basic part is understood as the main part of the product intended for its layout and installation of other component parts.

To the term "Unscheduled repair"

Unscheduled repairs are carried out in order to eliminate the consequences of failures or incidents.

To the term "Aggregate repair"

The opposite of the aggregate method is the detailed method, in which individual parts that have failed are replaced or restored.

To the indicators of the maintenance and repair system

The calculation of the indicators of the system of maintenance and repair of equipment is similar to the calculation of the corresponding indicators of maintainability in accordance with GOST 21623. At the same time, instead of operating costs, the total costs of time, labor and funds are taken into account.
