Another reason for preheating time shortens is: arranging cold solenoid valve 10 and exhaust-valve 11 while being opened, at first Interior that gas at normal temperature in pipeline is discharged first, otherwise, the air in thousands of mitron roads all needs that it is become heat by heat Water or hot gas could be discharged.Arrange cold solenoid valve 10, exhaust-valve 11 is at " the one fully automatic electric sub-controller of vapour three of industrial steam " Control under discharge air, be automatically switched off after drained air, and the condensed water of three vapour tail gas water filters 9 is internal by it Float switch carries out automatic-discharging.
Under control of one vapour three of industrial steam with electronic controller, when the temperature of No.1 barn 2 reaches 130 degree, one Vapour controls solenoid valve 4 and closes, and Second Automobile Works's compensation electromagnetic valve 16 automatically turns on, and main steam is compensated to No. two barns 22;It is baked when No. two When the temperature in room 22 reaches 100 degree, control pipeline Second Automobile Works solenoid valve 21 is closed, and transition solenoid valve 19 automatically turns on, and No.1 is baked After the Second Automobile Works that room is sent is directly fed to control three vapour water filter 29 of pipeline filtering by Second Automobile Works's transition conduit 18, it is supplied to electroplating region 28 use.Under specific circumstances, the temperature such as No. two barns 22 is inadequate, can open Second Automobile Works's manual compensation regulating valve 17 in right amount; If electroplating region 28 meets vapour amount deficiency, three vapour manual compensation regulating valve 26 of electroplating region can be opened in right amount.
It has passed through trimestral trial operation, entirely eliminated the use of oil-burning machine, not only avoid the oil of hot total energy consumption 40% Consumption expenditure and power consumption, machine damage, while also eliminating the pollution of oil smoke, and production efficiency, product quality all significantly improve.It is computed, Only saving heat energy fund just accounts for 20% or more.
