Modern industrial enterprises in their production process can not do without the use of instrumentation and automation. Automation has been introduced both at heavy engineering enterprises and in food production. In everyday life, installations are used to account for the consumption of water resources, electrical and thermal energy. The main purpose of the devices is to accurately determine the physical quantity. timely repairs and maintenance of instrumentation guarantee the accuracy of the devices.

Characteristics of measuring instruments

There are high requirements for quality characteristics and accuracy of measurements made to control and measuring devices. They form several groups:

• Devices for measuring pressure;
• Devices for measuring the volume of bulk and liquid substances;
• Devices for determining switching costs;
• Protection devices.

It is possible to determine the indications of a physical quantity on a scale and an installation indicator, they are classified according to the location of the scale. According to the location of the scale indicators, the devices are defined by two types: one-sided and two-sided. One-sided devices include devices in which the scale with the beginning of the readings is located on the left side and is limited to one direction. Dual-sided settings are devices where the zero scale position is located in the center and the values ​​​​are determined on the right and left sides of the center.

Types of repair work

Exclude emergency in production, you can use the recommendations of the provisions on maintenance and repair of instrumentation. The maintenance and repair system determines the types of repairs and the list of repairs, frequency of maintenance of instrumentation and instrumentation, consumption rates of materials and spare parts. The system of scheduled preventive maintenance includes checking of measuring instruments, major and current repairs, as well as maintenance of instrumentation and instrumentation.

The equipment of the enterprise involved in the production process is stopped for scheduled repairs, but there are also emergency stops. At the time of an emergency stop, repair operations are performed that cannot be performed with the equipment running. Planned stops are carried out on the basis of a schedule, which is formed taking into account frequency of instrumentation maintenance.

The maintenance of the equipment in working order ensures the monthly - TO-1, quarterly - TO-2, annual - TO-3. During the period of scheduled shutdowns, the dismantling of measuring structures, as well as automation equipment, pipe and cable wiring, is carried out. The duration of the repair period is determined on the basis of norms of time for maintenance of instrumentation.

List of requirements for performers of work

Ensure the performance of instrumentation and automation, specially trained workers. Given the complexity of automation systems, engineers and specialists with specialized education are engaged in launching the production of installations. depends on the performance of the equipment production activity enterprises.

Maintenance of instrumentation are carried out by employees of the enterprise or specialists of a contracting organization who have documents certifying the right to carry out repair work of measuring instruments. The contractor must have:

• trained personnel;
• repair base;
• Normative and technical documentation.

In fact, the mastered volumes of repair work are monthly drawn up bilaterally by an act of delivery of work performed.

The main goal of performing preventive repair work is to increase the productive efficiency of the enterprise, to ensure the safety of the production process. Also carry out control of production technology, ensure labor safety and environmental safety, equipment performance. The stability of the production process of the enterprise depends on the implementation of measures aimed at introducing new technology and replacement of obsolete equipment. accident-free manufacturing process provide scheduled preventive maintenance. Their planning is carried out taking into account the frequency maintenance of instrumentation and instrumentation.

Verification of instrumentation and automation is carried out to determine the conformity of characteristics state standards and technical conditions. Production metrological supervision regulated by GOST. Depending on the purpose of the tested measuring instrument, verification can be carried out public service or a departmental metrological organization.
