The compressor unit operator is a specialist who ensures the smooth operation of the compressor unit, maintains it, prepares it for starts and stops. In work, he must maintain the established technological rhythm.

Using automation tools, measuring and control devices, protection and alarm systems, as well as blocking, the compressor unit operator inspects the equipment and determines the causes of breakdowns, after which it eliminates them.

Requirements

The job description for a compressor unit operator describes a list of duties that require the absence of contraindications. If an employee has he alth problems, then it is strictly forbidden to work at this installation.

The compressor plant operator must have vision that is resistant to fatigue. Sharp vision with normal color discrimination is one of the important criteria.

Good hearing, keen sense of smell, developed memory - qualities that must be at a high level.

Physically demanding work requires a lot of endurance. In case of he alth problems, as a result of which great physical exertion and monotonous work are contraindicated, the employee must be relieved of his post.

The ability to work in a large team is an important personal skill, without which it is difficult to imagine the work of a mechanic.

Contraindications to work in this position are violations of the vestibular apparatus, hearing and vision impairment, predisposition to colds.

Qualifications

Difficult and responsible work for this employee. The compressor unit operator must have extensive knowledge in the field of chemistry, physics, and electrical engineering. Knowledge of the types and types of control and measuring tools and devices is required to perform work efficiently.

Knowledge of the technological processes used in production is the key to successful work.

It is also necessary to know the principles of operation of the installation, the design of the compressor, electric motors, as well as the instruments with which measurements are taken.

Discharges

According to the handbook, there are 5 categories of compressor unit operators. For each, their own requirements for professional training are put forward, as well as the duties that an employee in this position must perform.

In the ETKS classifier, machinists of the second, third, fourth, fifth and sixth categories are distinguished.

The highestis the second category, it is subject to the highest requirements for experience and skills. The sixth, respectively, is the lowest.

The ranks of the compressor unit operator are assigned according to work experience. Responsibilities depend on the category, as well as the level of remuneration.

An employee with a third grade should know:

• device of turbocompressors, reciprocating compressors, internal combustion engines, electric motors, steam engines and installations;
• technical characteristics of the described units and rules for their maintenance;
• measuring equipment device, service rules and specifications;
• installation piping diagram;
• documentation required for the installation to work;
• fundamentals of thermodynamics, as well as electrical engineering;
• properties of gases in compressor operation.

Fourth rank

A driver with the specified category serves turbochargers and stationary compressors up to 10 kgf/cm² (1 MPa). The feed in these plants is more than 100 m^3/min.

The job is:

• establishing and maintaining an advantageous mode for compressor operation;
• monitoring the he alth of engines, instruments, mechanisms;
• participation in the inspection and repair of equipment (according to the qualifications of a locksmith with 3 categories).

Knowledge for the fourth grade

To perform duties at a high level, you must know:

• layouts of pipelines, steam lines, tanks and fittings of the compressor station;
• schemes according to which the automatic device for blocking the operation of the station is located;
• technical specifications of compressors to be serviced;
• norms of electricity consumption for the normal operation of the station;
• Consumption rates for materials to produce gases or compressed air.

Fifth rank

A driver of the fifth category serves automated stations up to 100 m3/min.

His duties are:

• switching, as well as putting equipment into repair and standby;
• process control;
• compiling defect reports and equipment repair records;
• carrying out repairs of station equipment (qualification of a mechanic 4 categories);
