Matters dealt with injection molding machine was flooded after

Usually after the injection molding machine may result in different levels of water flooded the electrical control box inside the electrical machine hydraulic systems, lubrication systems, in this case, can be divided into the following sections to analyze the process:

    First, the electrical control part

    After the injection molding machine electrical parts water, it can cause a variety of electrical injection molding machine original rust corrosion and insulation performance phenomenon. Usually following the steps below:

    1. Disconnect all power injection molding machine;

    2, in the injection molding machine after flooding in the shortest time, the I / O PC board above the battery is removed (recommended customers timely operation) because I / O board in the case of the battery is not removed, the individual components is still powered state, it will accelerate rust and corrosion extent of these elements will increase the difficulty of elements maintenance and repair costs;

    3, the whole point of the injection molding machine inside the electrical components Remove (service operation) cleaned with alcohol, if necessary to break down the parts cleaning, including the I / O board, 24V power supply, 5V power supply, transformers, AC contactors, air switches, axial fans and so on;

    4, dried, and the drying hopper will all live components sufficiently dried, decomposition of cleaning elements can be layered into a clean, after drying hopper and dried at a temperature of 50 ~ 70 ℃, drying time of 8 to 10 hours, the insulation resistance test Meets requirements (generally measured with 200K file), it is determined whether or not completely dry;

    5, the electrical parts dried completely separate power check (service operation), the check can only be installed using intact.

    Second, part of the hydraulic injection molding machine

    1, can not open the injection molding machine motor pump, because the open hydraulic injection molding machine motor oil into the water may enter the hydraulic line system injection molding machine, hydraulic components cause the metal corrosion;

    2. Check the injection molding machine hydraulic oil is water. Open the plug on the injection molding machine frame bottom of the tank, releasing a small amount of oil, with a piece of paper stained with a little light, if you can not ignite the fire burning in the process of crackling Baoxiang, then the hydraulic oil in the water, we need to replace all the hydraulic oil. (Anhydrous copper sulfate can also be used to test whether or not becomes blue, then the blue water);

    3, if the water content in the oil, replace the injection molding machine hydraulic oil tank. Before oil change use a clean cloth to wipe the tank;

    Third, the rest of the

    1, injection molding machine motor

    The motor stator and rotor separated from the stator winding drying treatment (allows professional motor repair process, you can also use 100W incandescent thorough drying processing motor housing about 8 hours), insulation resistance must ensure ≥0.4MΩ, injection machine motor bearings removed by cleaning after checking whether the use of gasoline, are then replaced with the specifications bearings;

    2, injection molding machine lubrication pump

    The injection molding machine lubrication pump rotor, a stator and a pump bile separation, fixed set of windings can be used for drying the drying hopper, the insulation resistance must ensure ≥0.4MΩ, pump gall rust stuck if you can die rust agent sprayed into the pump gall rust inside, the gear pump can be flexible rotation within the bladder.

    3, sub-size models of the injection molding machine must take the connector plug, connector socket (air plug) separately, dried (hair dryer available) after cleaning.

    Fourth, the injection molding machine servo motor and control system

    1, the injection molding machine electrical components, circuit board first with alcohol and then cleaned by air drying or oven drying hopper to 55 ℃ dried for 24 hours.

    2, injection molding machine servo motor Note encoder and motor stator drying and motor bearing protection, to prevent rust.

    After the above ministries processed, re-assembled parts, power test machine.
