1. Classification of compressors.

Appointment. The compressor is used to compress, pressurize and move (transport) air or gas. A compressor is the basis of a compressor unit, which, in addition to it, includes auxiliary interstage units, a drive, gas pipelines and various systems (lubrication, cooling and regulation).

Compressors are used in 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 immediate purpose (starting air, brake air, pumping, etc.).

By principle of action compressors are divided into volumetric and dynamic. The former include reciprocating piston compressors, rotary (vane ) with rotary movement of displacer pistons, screw with variable pitch rotors and diaphragm, 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 distinguish between low pressure compressors that create a gas pressure of 0.2 ... 1.0 MPa (2 ... 10 kgf / cm 2), average -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 small (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 subdivided into machines with cooling (air or water) of the compressor and the discharge gas;

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

on type of installation- on stationary (on a foundation or special supports) and mobile (on a chassis or frame). 2. Design and purpose of separators and filters included in compressor units and requirements for them.

Separators (Oil Water Separators) are used to clean the gas from oil and moisture (in turbochargers - from moisture). The separation occurs when a sharp change in the direction of the gas flow due to the different density of the gas and the droplets of oil and moisture contained in it. 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 an outlet that changes the direction of the flow (Fig.

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

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

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

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

The filtering device should not deform and vibrate when air is sucked in by the compressor.

2.47. Filtering devices can 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 a 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 an end cooler and a moisture-oil separator in one apparatus.

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

Dehumidification units operating on the method of moisture absorption by solid sorbents and using non-toxic and non-explosive refrigerants can be located in the machine room of the compressor unit.

3. Preparing to start, starting and stopping the reciprocating compressor.

Compressor preparation for start-up

4. The system of scheduled 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-drawn up plan and contributing to an increase in its durability with optimal operating parameters, prevention of accidents, 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 service

Maintenance

medium repair

major overhaul.

Maintenance is a complex of works on monitoring the technical condition of equipment, timely warning, manifestation of a malfunction, replacement of quickly wearing parts, which entails _ minor disassembly of the equipment. At the same time, the volume is specified

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

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

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

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

failure to comply with fire safety requirements when placing and arranging the equipment of the installation;

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

All fire safety measures can be divided into two groups - fire prevention (prophylaxis) and elimination of an already existing fire.

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

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

Measures are provided to ensure the evacuation of people and property in the event of a fire. These include: 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 those ensuring the successful extinguishing of a fire in the event of a fire.

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

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