In injection mold
ing machine often flooded, will likely form electrical control box inside the electrical machine hydraulic system, the smooth system, such as different levels of water, in this case, how should we deal with?
After vertical injection molding machine
factory for many years of experience can divide some to analyze the disposal.
A, electrical control, after some electric water can form all kinds of electrical original surface rust corrosion and insulation function decline.
Usually according to the following steps: 1, disconnect all power supply;
2, within the shortest time after the water, will I/O computer host plate under the battery from above (
Claims timely operation)
Because of I/O board did not remove the battery case, a single element is still in the current situation, this will speed up these components rust and corrosion degree, will increase the difficulty of the component repair and repair cost;
3, the whole point of the electrical components in the cabinet will be removed (
Using alcohol to clean, if necessary to clean parts differentiation, contains the I/O board, 24 v power supply, 5 v power supply, transformer, communication, contactor, air switch, axial flow fan, etc. ;
4, boring, use the hopper will all components and boring, boring differentiation after clean cleaning element can be stratified into the hopper, boring boring temperature in 50 ~ 70 ℃, boring time 8 ~ 10 hours, test the insulation resistance value whether meet the requirements (
Usually use a 200 k file measurement)
Discrimination is completely boring;
5, will dry electrical components of the current view (alone,
, the view can only be installed using.
Second, some 1, can't open the hydraulic motor pump, due to open after the motor in the hydraulic oil into the water enters the machine hydraulic piping system, may lead to metal hydraulic components corrosion;
2, check the hydraulic oil is water.
Open rack plug at the bottom of the tank, released a few oil, use paper with small amounts of light, if not on fire burning has a crack in the process of explosive, then clarify with water in the hydraulic oil, hydraulic oil demand to replace all.
Also using anhydrous copper sulfate test is blue, blue is clarified water)
3, if the oil in the water, the demand to replace the hydraulic oil tank.
To scrub with a clean cloth tank before oil change;
Three, other some 1, separate the motor stator and rotor, motor stator winding boring disposal (
Can make professional repair motor disposition, also can use 100 w bulb to deepen inside the motor housing drying for the disposal of about 8 hours)
, it is necessary to ensure insulation resistance & ge;
, a motor bearing down with gasoline can see use after cleaning, are replaced with standard bearings;
2, smooth smooth pump will pump motor, stator and rotor pump bravery separation, fixed set of winding can use boring hopper for drying treatment, it is necessary to ensure insulation resistance & ge;
, pump if rust stuck to use mould bravery inside cleaning rust remover spray into the pump, pump bravery in sensitive gears.
3, size models (
UN320 above models)
Is bound to the adapter plugs, adapter socket (
Separately, dry after cleaning disposal (
Can use hair dryer)
Four 1, servo motor and control system, electrical components, circuit boards to use alcohol clean clean with the wind blow dry or boring in the oven again after hopper to 55 ℃ dry for 24 hours.
2, servo motor of the encoder and motor stator boring and bearing protection, avoid rust.
Finally, vertical injection molding machine factory is pointed out that the various parts of the above treatment has been completed, from the beginning to parts installed, electricity of commissioning.
