Type - three-phase asynchronous with squirrel-cage rotor

Power, kW - 37

Voltage, V - 220/380

12.1 Before starting the compressor, after completing the work provided for in section 2, it is necessary:

A) check the oil level in the crankcase using the oil gauge, top up if necessary;

b) turn on the compressor in automatic mode;

When the pressure in the air collector is below the minimum (start pressure) according to the pressure switch, the compressor should start, a light signal is issued to the control panel;

If the air pressure is above the minimum, it is necessary to reduce it to the minimum;

V) check the performance control by stopping, for which it is necessary to raise the pressure in the air collector to the maximum, closing the outlet valve. In this case, the compressor should automatically stop with the simultaneous activation of purge and unloading (bypass).

The valves remain on during the entire time the compressor is inactive and turn off automatically the next time the compressor starts (when the pressure drops to the minimum);

G) check the performance control by bypass, for
then move the switch for selecting the method of regulating the performance on the control panel to the “Bypass” position.

Raise the air pressure in the air collector to maximum. At the same time, the purge is turned on and the bypass valve opens, the compressor begins to work as a bypass;

d) alternately check the emergency protection for overheating of the 1st and 2nd stages of the compressor, for which it is necessary to stop the compressor in accordance with clause 11.6.

Unscrew the temperature sensors (stages 1 and 2), place them one by one in a bath with preheated oil to a depth of at least 20 mm and slowly heat them in the bath until completely heated (at least 10 minutes). Turn on the compressor to operate without load.

When the temperature rises to 180±5°C, the compressor must stop with the purge and unloading turned on, and a light signal is issued to the control panel (SCUS) “Overheating 1 stage.” or “Overheat 2 stages.” depending on the accessory of the sensor being tested.

At the end of the check, screw the sensors into place,

e) start the compressor in automatic mode:

12.2 Compressor maintenance during operation (every shift)

When servicing the compressor every shift, you must:

A) control the oil level in the crankcase, which should not be below the bottom mark on the oil indicator; add oil to the crankcase through a funnel with a mesh into the compressor breather;

b) as the filter elements (cloth) of the air filters become dirty, they must be washed from dirt with any cleaning solution;

V) every 4-5 hours of continuous operation of the compressor, perform a purge by pressing the “Purge” button on the control panel;

G) If the compressor stops due to emergency protection, the maintenance personnel, having found out the cause of the malfunction, should flash a signal by turning off the power to the control panel. To carry out troubleshooting work, it is necessary to turn off the power to the compressor at the distribution board;

d) monitor pressure using pressure gauges. The pressure in the 1st stage should be 0.17-0.22 MPa (1.7-2.2 kgf/cm2), the pressure in the 2nd stage - 0.78 MPa (8 kgf/cm2);

e) monitor the tightness of the connections and, if leaks are detected, eliminate them; however, tightening the nuts and bolts while the compressor is running is not allowed;

and) The air collector must be ventilated at least 2 times a day; V winter time the air collector must be purged before each long stop of the compressor to prevent moisture from freezing in it;

h) check daily safety valves by forcing them open under pressure. After closing, the valve must remain completely sealed;

And) check and, if necessary, adjust the belt tension using the adjusting bolt on the fan. The belt deflection under a force of 4 kgf/cm should be within 15±20 mm;

To) Check the tightness of the nuts on the impeller and fan shaft.

12.3 When working with manual control in the cases provided for in clause 7.4. it is necessary to carry out measures in accordance with clause 12.1 and clause 12.2 a), b), c) and d-l), while monitoring the pressure must be regular.

12.4 Stopping the compressor

12.4.1. The compressor is stopped in accordance with clause 11.6.

12.4.2 . If the compressor operates in an unheated room and does not use the oils specified in paragraph 11.1, in the winter, when stopping for a long time, it is necessary to drain the oil from the crankcase.
