Cooling water pressure redu

30、cing alarmDuring the operation, when the inlet pressure of cooling water lower than 0.2MPa, alarms, at the same time, the electromagnetic valve closes all its actions, cuts off the water circuit, when things happened like that, find the reasons then repair it(reasons, see the descriptions in the mal

31、function analysis column), the cooling water recovers the normal working status. If the electromagnetic valve does not actionnot opened, do according to 5.4.2.5.6. Debugging of the safe valve5.6.1. The safe valve is set between the flux-control valve and the flowmeter, setting working pressure of 0.

32、6MPa, acting pressure of 0.8MPa, when the flow circuit has overloading pressure, the safe valve automatically unloads. The safe valve is regulated well when leaving the factory, normally does not need regulating during the unit working. When it operates for a period of time or finds any malfunction,

33、 if need be, rechecks and regulates the safe valve as below:Connect pressure meters at the rear of the safe valve and between the connective pipes of the safe valve (range of 1MPa), close the water circuit to the instrument, regulate the manual sampling valve to raise the interior pressure of the sa
