(3) with sealing ring (2) from the body. If necessary, clean the valve body
(8) contact chamfer of the valve couple using a cloth.
Replace the valve couple and reassemble in reverse order, applying a
small amount of CYATIM ST 6267-80 lubricant to the rubber sealing ring
surface of the seating.
(The seating is chamfered on one side at the outside diameter. The
chamfer is small so it must be determined accurately prior to assembly.
The seat must be chamfered to the inside of the body).
8.2.3. Flushing and lubricating the interface connector
Flushing is performed with pure ethyl alcohol or alcohol-gasoline
mixture using a brush (1 part ethyl alcohol, 1 part petrol "Kalosha" or
"Nefras", no other petrol allowed). Alcohol consumption is 30g per month
of use. After washing, apply a small amount of CYATIM lubricant GOST
6267-80 to the connector surface.
8.2.4. Operation monitoring
The main parameters of the level gauge are monitored for the
following operating modes:
1) checking the setting of the setting and display modes,
2) checking in mode Level and pressure monitoring,
3) checking of sensitivity and noise level of the acoustic path,
4) check in mode Automatic Pressure Registration,
5) Test of the maximum working pressure control (max 100 atm),
6) check in the mode of the battery capacity control.
Methodology of checks is presented in the "Manual on conducting
verification tests of devices and complexes manufactured by TSIIC
"SIAM" LLC in operation". Tests 2 and 3 are performed at the Level gauge
control test bench SKU-1 IZM 4.137.003 (SIAM company). Test 5 is
carried out on the hydraulic test bench SGI-1 IZM 4.137.002 (SIAM
company).
