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

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

b) turn on the compressor in automatic mode;

When the pressure in the air collector is lower than the minimum (starting pressure) according to the pressure turnip, the compressor should start, a light signal is issued to the SCHUS;

When the air pressure is higher than the minimum, it is necessary to lower it to the minimum;

in) check the capacity regulation by stopping, for which it is necessary to raise the pressure in the air receiver to the maximum, closing the outlet valve. In this case, the compressor should automatically stop with the simultaneous inclusion of purging and unloading (bypass).

The valves remain on during the entire period of inactivity of the compressor and turn off automatically at the next start of the compressor (when the pressure drops to the minimum);

d) check the capacity regulation by bypass, for
then switch the switch for selecting the method of performance regulation on the control panel to the "Bypass" position.

Raise the air pressure in the air receiver to the maximum. In this case, the purge is turned on and the bypass valve opens, the compressor starts to work on bypass;

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

Unscrew the temperature sensors (steps 1 and P), place them alternately in a bath with preheated oil to a depth of at least 20 mm and slowly warm them up in the bath until fully heated (at least 10 minutes). Switch the compressor on without load.

When the temperature rises to 180 ± 5 ° C, the compressor should stop with the purge and unloading turned on, while a light signal is issued to the control panel (SCHUS) "Overheating of stage 1" or "Overheating 2 tbsp." depending on the accessory of the tested sensor.

At the end of the test, screw the sensors back into place,

e)start the compressor in automatic mode:

12.2 Compressor maintenance during operation (every shift)

When servicing the compressor every shift, it is necessary:

and)check the oil level in the crankcase, which should not be below the lower mark on the oil gauge; add oil to the crankcase through a funnel with a mesh into the compressor breather;

b) as the filter elements (cloth) of air filters become dirty, it is necessary to rinse them from dirt with any cleaning solution;

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

d) in the event of a compressor stopping due to the activation of the emergency protection, the maintenance personnel, having found out the cause of the malfunction, the signal should shine by turning off the power to the control panel. To carry out work to eliminate the malfunction, turn off the power to the compressor at the switchboard;

e) control the pressure according to the readings of the manometers. 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 should be 0.78 MPa (8 kgf / cm2);

e) monitor the tightness of the connections and, if any non-tightness is found, eliminate them, while tightening the nuts and bolts on the running compressor is not allowed;

g) purge the air collector at least 2 times a day; in winter time the air collector must be purged before each long shutdown of the compressor to avoid moisture freezing in it;

h) check the safety valves daily by forcing them to 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. Belt deflection under 4 kgf / cm force should be within 15 ± 20 mm;

to) check the tightness of the nuts on the impeller and fan shaft.

12.3 When working on 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 should be regular.

12.4 Stopping the compressor

12.4.1. The compressor is stopped according to clause 11.6.

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