Fig. 3.112. Check of resistance of the valve of switching
|
Check resistance of valves of switching, the electromagnetic valve of synchronization and the electromagnetic valve of the hydrotransformer (fig. 3.112). Nominal rate of resistance of electromagnetic valves of switching, synchronization and hydrotransformer: 11–15 Ohms at 20 °C.
Work check
Valve of switching of A (No. 1), B (No. 2) and electromagnetic valve of the hydrotransformer
|
ATTENTION
Do not install the pneumogun for air supply in the valve too close to the mesh filter installed on an entrance of the electromagnetic valve. Otherwise, the mesh filter will be damaged.
|
Make sure that the electromagnetic valve works with click when giving of tension on it from the rechargeable battery.
Make sure that the electromagnetic valve connected to the rechargeable battery is in the closed state giving to it air under pressure of 50–200 kPa.
Make sure that the electromagnetic valve which is not connected to the rechargeable battery is abroach giving to it air under pressure of 50–200 kPa.
|
NOTE
Use compressed air for check to avoid wrong results because the electromagnetic valve has no returnable spring.
