High Frequency machine repair and maintenance

　　Induction FAQ

　　1 regularly check water filters;

　　(2) If the machine has a dust for dry compressed air blown clean the machine carefully, but must shut off the main power supply;

　　Problem: After checking, be sure to turn off the main power, because there are thousands of volts machine first million volts.

　　Phenomenon 1: Common red (overload lamp)

　　Cause: A) lower mold insulating material damage.

　　B) the work material, or the upper and lower mold vibrating cylinder dirt, dust, moisture need to clean up.

　　C) the level of high frequency machine up and down mode bit bad.

　　D) upper and lower die without insulation, and direct touch together.

　　E) high-frequency input power is too high.

　　F) frequency machine vacuum damaged or loose.

　　G) Over Power Protection electronic board is damaged. Overcurrent protection board that is three appliances that a total.

　　H) frequency machine with the adjuster is too large, the output is too high.

　　I) work piece is too large, the same machine beyond the rated output.

　　J) Thermostat part failure.

　　K) high voltage capacitor damage.

　　L) high frequency machine insulated column (on the template) damaged.

　　Phenomenon 2: high-cycle output, total supply is disconnected or burning fuse

　　Cause: A) vacuum tube failure. B) transformer fault.

　　C) high voltage rectifier board failure. D) three-phase magnetic switch damaged.

　　E) high voltage lines short barrier. F) electric board failure.

　　Phenomenon 3: No Output

　　Cause: A) switch is defective. B) line fault. C) vacuum tube failure.

　　Phenomenon 4: workload bad

　　Cause: A) Adjustment bad. B) the mold problem.

　　C) plastic pieces (work piece) problem. D) thick insulation, insulation too high.

　　Note: When the mold under the pressure encountered lower die, you must hold the make up ground copper plate, round copper can be slightly distorted. If this did not adjust well grounded copper, this station will not be stable mechanical work. When replacing the different heights of the mold when this grounding copper should be subject to re-adjust again.

　　Two high-frequency operation sequence Dongguan

　　1 first-phase power switch turned on, and then turn on the machine side of the control box power switch, if there is high-cycle switch, not yet marked, then marked with an electric power switch, this time, vacuum tubes and are beginning to pre-heat mode heat.

　　(2) on the lower die and auxiliary insulation, installed on the extreme upper die tryout press the switch, start debugging the upper and lower mold engagement position, if the next poor bonding, it moves the lower die, if the level or not, on the transfer of four compared to the previous model pillar child.

　　Three high frequency machine die after a good tune, adjust the three-time controller (if it is pedal-type machine, only the high-cycle Fuser time), fall time that is pressed on to the lower mold die run time, the time that the fuser Output time, cooling time, that the curing time, the three time to be flexible application, there is no fixed number of values.

　　4 If the first transfer mode, the need to adjust the tuning tune with the widest spacing transferred.

　　5 above operation if more than 10-15 minutes, and the temperature has reached the desired time, the high-cycle switch marked, began operation test.

　　6 test, if the result is not satisfactory, the need to go together with the adjuster slowly, watching the screen flow table (different models with different values ​​in this table, please refer to the manual). Check the product, if not ideal, put the same adjuster add a little or a little less, until it reaches the requirements.

　　7 The finished effect, determined by the following four aspects:

　　A) Temperature B) cohomology power output C) Pressure D) Output High weeks.

　　These four areas, please flexibly adjusted.

　　Three Dongguan High Frequency (HF) Precautions

　　1 Jolo machinery necessary to put on a good grounding terminal (connected to the correct ground)

　　2 machine to moisture, dust is extremely sensitive, to be placed in the appropriate workspace.

　　3 vacuum tube machine will produce heat, so the heat generated can not be placed on the side of the machine, nor device in the solar direct radiation to the place, due to the above reasons will affect the vacuum tube heat dissipation.

　　4 Stop the machine if more than one hour, and then boot, you need to wait 10-15 minutes for the vacuum preheating, protection tube life.

　　5 machine up and down the extreme (upper and lower mold) not directly touch together, must have insulation between them and work pieces.

　　6 operation, when the high-frequency output, remember not to touch the upper pole of the output (ie, the upper die), neither universal table, test meter, or other low-frequency, low-pressure meter, try to directly measure the output of the upper pole, it will lead to accidents.

　　7 periodic inspection under extreme (lower die) of insulating material, if damaged, burned, breakdown place to be immediately replaced insulation, or if they continue to work, it will produce a spark, unable to complete the process.

　　8 If a spark occurs frequently phenomenon (in the upper and lower mold met, and high-cycle output) rather than to check the repair will cause damage to internal parts, affecting work.

　　9 used to make the finished work piece, as far as possible shall have no moisture, dust, due to the above objects easily lead to sparks.

　　10 machine power is turned on, you will hear the sound of the fan rotation (4KW, 5KW sound less), this is the vacuum tube heat dissipation, if a fan fails, you must immediately repair, or will cause damage to the vacuum tube.
