The cooling pure water system working principle in the inside of equipment: control button of the starting on heating furnace electric cabinet 2-21, it is raw After producing line equipment (heating furnace 2-8, forging roll 2-9, hydraulic hammer 2-10, other production line ancillary equipments 2-11 etc.) successively starts, The system starts the second water pump 2-3 automatically, reaches production line by the second anti-cleaning filter 2-5 and second heat exchanger 2-6 Equipment (heating furnace 2-8, forging roll 2-9, hydraulic hammer 2-10, other production line ancillary equipments 2-11 etc.) realizes high-temperature water after cooling Continue cooling equipment after the cooling of heat exchanger 6 and realizes a circulation.Second temperature sensor 2-12 is controlled by PLC controller Second electric control valve 2-7, the second electric control valve 2-7 avoids energy waste, pressure sensor according to temperature automatic control water By pressure monitor second, anti-cleaning filter 2-5 and heat exchanger 6, second pressure gauge 2-14 facilitate an inspection, examine equipment 2-13 Whether work normally, softened water adds water solenoid valve 2-15 to add softened water automatically when controlling by PLC and find that water level is too low.

A kind of control method of the feed water control system of finish forge production line of the invention, comprising the following steps:

Step S1: being adjusted to the automatic control mode of feed water control system using electric cabinet 2-4 startup power supply, automatically controls Mode include production line during normal production waterway circulating, stop production when drain line circulation and control reservoir water line cycle；

Production line during normal production waterway circulating the following steps are included:

Step S2-11: cold using the first temperature sensor 1-9 detection device being arranged on the cooling water inlet pipe 1-3 of equipment But the temperature value on water inlet pipe and electric cabinet 2-4 is sent a signal to, electric cabinet 2-4 controls the first motorized adjustment according to temperature signal Valve 1-21 opens size；

Step S2-12: cold using the first pressure sensor 1-10 detection device being arranged on the cooling water inlet pipe 1-3 of equipment But the pressure value in water inlet pipe 1-3 and electric cabinet 2-4 is sent a signal to, whether electric cabinet 2-4 is lower than pressure based on the feedback signal Setting value；When the pressure value in the cooling water inlet pipe 1-3 of equipment is lower than pressure set points, the first of the electric cabinet 2-4 control free time Suction pump 1-6 starting, the first suction pump 1-6 are drawn water by corresponding water supplying pipe 1-2 from reservoir, when in the cooling water inlet pipe of equipment Pressure value when being higher than pressure set points, the first suction pump 1-6 of electric cabinet 2-4 control operation is closed, and the first suction pump 1-6 stops Only drawn water by corresponding water supplying pipe 1-2 from reservoir；

The water that step the S2-13: the first suction pump 1-6 is extracted converges to the cooling water inlet pipe 1-3 of equipment, by equipment it is cooling into The cryogenic high pressure cold water of water pipe 1-3 by the first anti-cleaning filter 1-11 remove impurity it is laggard enter production line；

Step S2-14: the high-temperature water that production line generates returns to reservoir by first heat exchanger 1-15 and completes a job Circulation；

Step S2-15: the dirty water of the first anti-cleaning filter 1-11 filtering is discharged into dirty water using the first drainpipe 1-18 In well 1-17；

Step S2: when production line stops production, drain line circulation when halt production the following steps are included:

Step S2-21: the cooling water inlet pipe 1-3 of equipment is located at the 4th connecting tube being arranged at the first anti-cleaning filter 1-11 1-26 prevents winter pipeline from freezing for emptying water accumulation of pipeline, cools back water pipe 1-4 in equipment and is located at first heat exchanger 1-15 4th connecting tube 1-26 of place's setting prevents winter pipeline from freezing for emptying water accumulation of pipeline, the 4th connection of electric cabinet 2-4 control The opening and closing of non-freezing drainage valve 1-16 on pipe 1-26；

Step S2-22: the cooling water inlet pipe 1-3 of equipment and equipment are cooled back in water pipe 1-4 using the 4th connecting tube 1-26 Ponding be discharged into dirty water well 1-17；

Step S3: in fabrication line process reservoir control reservoir water line cycle the following steps are included:

Step S31: being provided with the first electric control valve 1-21 on water injection pipe, electric cabinet 2-4 controls the first electric control valve 1-21 is filled the water to reservoir；

When electric cabinet 2-4 has found the first suction pump 1-6 failure in step 1, the first temperature sensor 1-9 and first is utilized The real-time detection of pressure sensor 1-10 simultaneously sends a signal to electric cabinet 2-4 (6es7-288-1sr60-OAAO), electric cabinet 2-4 It was found that electric cabinet 2-4 repeats step after the feedback signal exception of the first temperature sensor 1-9 and first pressure sensor 1-10 S2-12 simultaneously controls alarm lamp or buzzer warning.

Electric cabinet 2-4 controls two sets of cooling recirculation systems on the cooling water inlet pipe 1-3 of equipment, electric cabinet 2-4 difference respectively First temperature sensor 1-9, first pressure sensor the 1-10 information fed back are compared, only two group of first temperature sensing For the error amount of device 1-9 and first pressure sensor 1-10 in the range of setting, electric cabinet 2-4, which just can control, executes next behaviour Make, to guarantee first pressure gauge 1-8, the first temperature sensor 1-9, first pressure sensor 1-10, the first anti-cleaning filter After breaking down, maloperation problem occurs 1-11 for electric cabinet 2-4.
