Compressor unit operator, 4th category

1. Classification of compressors.

Appointment. The compressor is used to compress, increase pressure and move (transport) air or gas. The compressor is the basis of the compressor unit, which, in addition to it, includes auxiliary interstage devices, a drive, gas pipelines and various systems (lubricating, cooling and regulating).

Compressors are used in the chemical, metallurgical and mining industry, energy, mechanical engineering, construction, transport and other sectors of the national economy to ensure the technological process of production and for auxiliary purposes.

Classification. Compressors are classified according to purpose, principle of operation, final pressure, supply, method of heat removal, type of drive, type of installation.

By appointment compressors are classified depending on the type of production in which they are used (chemical, gas pumping, general purpose, etc.), as well as for their intended purpose (starting air, brake air, pumping, etc.).

By operating principle compressors are divided into volumetric and dynamic. The first include reciprocating piston compressors, rotary (vane ) with rotational movement of the displacing pistons, screw with variable pitch rotors and membrane, in which the membrane plays the role of a piston. Dynamic compressors (turbocompressors) are divided into centrifugal with a gas flow directed radially from the center to the periphery, and axial with a gas flow moving in the axial direction when the wheel with blades rotates.

By final pressure there are low-pressure compressors that create a gas pressure of 0.2 ... 1.0 MPa (2 ... 10 kgf / cm 2), medium -1 ... 10 MPa (10 ... 100 kgf / cm 2), high -10 ... 100 MPa (100 ... 1000 kgf / cm 2) and ultra-high pressure - over 100 MPa (1000 kgf / cm 2).

By filing compressors are divided into machines with low (up to 0.015 m: 7s), medium (0.015 ... 1.500 m 3 / s) and large (over 1.500 m 3 / s) feed, different for each type of compressor (volumetric or dynamic).

By method of heat removal compressors are divided into machines with cooling (air or water) of the compressor and the injected gas;

By drive type- for compressors with an electric motor, steam or gas turbine, ICE;

By type of installation- stationary (on a foundation or special supports) and mobile (on a chassis or frame). 2. Device and purpose of separators and filters that are part of compressor units and requirements for them.

Separators (Oil-moisture separators) are used to purify gas from oil and moisture (in turbochargers - from moisture). Separation occurs when a sharp change in the direction of the gas flow due to different density gas and the drops of oil and moisture it contains. The direction of the gas flow is changed by installing additional partitions in the cylindrical body, placing the gas inlet and outlet pipes at an angle, or making the inlet pipe in the form of a branch that changes the flow direction (Fig.

2.45. The intake (suction) of air by an air compressor should be carried out outside the compressor station at a height of at least 3 m from the ground level.

For air compressors with a capacity of up to 10 m 3 /min., having air filters on the machine, it is allowed to take air from the compressor station room.

2.46. To clean the intake air from dust, the compressor intake air duct is equipped with a filter protected from atmospheric precipitation.

The design of the filter device should provide safe and convenient access to the filter for cleaning and disassembly.

The filtering device must not be deformed or vibrate when air is drawn in by the compressor.

2.47. Filtering devices may be individual or common to several compressors. In the latter case, for each compressor, it should be possible to disconnect it (in case of repair) from the common suction pipeline.

2.48. For enterprises where high dust content of the intake air is possible, compressor units should be equipped with filters and other special equipment in accordance with the project documentation.

2.49. In compressors equipped with end coolers, moisture-oil separators should be provided on the pipelines between the cooler and the air collector. It is allowed to combine the end cooler and moisture-oil separator in one apparatus.

2.50. If it is necessary to have deeply dried air, in addition to the end coolers, the compressors are equipped with special drying units. Dehumidifiers operating according to the method of freezing moisture with the help of refrigeration units must be located in rooms isolated from the compressor unit.

Dehumidifiers operating on the method of absorbing moisture with solid sorbents and using non-toxic and non-explosive refrigerants can be located in the engine room of the compressor unit.

3. Preparation for start-up, start-up and stop of the reciprocating compressor.

4. The system of planned preventive maintenance of equipment, its essence and goals.

The PPR system is a set of organizational and technical measures for the supervision, maintenance and repair of equipment carried out according to a pre-planned plan and contributing to an increase in its durability with optimal operating parameters, accident prevention, an increase in the culture of operation and the level of organization of repairs.

The PPR provision provides for the following types of repair and overhaul maintenance:

overhaul maintenance

Maintenance

average repair

overhaul.

Maintenance is a set of works to monitor the technical condition of equipment, timely warning, manifestation of a malfunction, replacement of wear parts, which entails _ minor disassembly of equipment. This specifies the volume

preparatory work for current, medium, and major repairs. During the maintenance period, the equipment is switched off from technological cycle(stops). At the same time, only such equipment malfunctions are detected and immediately eliminated, in the presence of which it cannot be operated normally until the next repair. Maintenance is carried out by repair personnel under the guidance of a repair service mechanic.

5. Causes of fires during the operation of compressor units and fire prevention measures.

At oil and gas refineries, where large quantities of combustible gases and liquids are processed and stored, fire prevention measures are organically linked to the technological process itself. In factories, fires can occur as a result of various organizational and technical shortcomings, for example:

deviation from the established mode of operation of the installation (temperature, pressure) and irregular preventive inspection of equipment;

non-compliance with fire-fighting requirements when placing and arranging the equipment of the installation;

non-compliance with the fire regulations established for this installation.

All events for fire safety can be divided into two groups - the prevention (prevention) of fires and the elimination of an already existing fire.

Fire prevention is a set of measures aimed at preventing fires and limiting their size.

Elimination of the causes of fires is achieved the right choice and arrangement of technological and auxiliary equipment. Limitation of the spread of fire is carried out: by measures of the design and construction order, including proper planning and placement of buildings and equipment; the use of structures and materials that meet the requirements of fire regulations; arrangement of fire zones and embankments.

Measures are provided to ensure the evacuation of people and property in case of fire. This includes: the arrangement of the required number of stairs, doors, passages both on the territory of the installations and in the premises; placement of devices in compliance with the required width of the passage or passage between them; emergency lighting device and others.

Preventive measures also include ensuring the successful extinguishing of a fire in the event of a fire.

For example, the device of roads for free access by frying machines to buildings and structures; communication with the fire brigade; providing the enterprise with a sufficient amount of the necessary fire extinguishing means (fire extinguishers, water, sand, etc.).

Important role in ensuring fire safety is assigned to the heads of workshops, installations, foremen. Being responsible for fire safety in their area, they are obliged to develop, together with the authorities fire brigade fire safety instructions, train subordinate personnel in the measures to be taken in the event of a fire, as well as the rules for using fire extinguishing equipment.
