The treatment of vertical injection molding machine after being flooded

General vertical injection molding machine is flooded may cause electrical control box inside the electrical, machine hydraulic system, lubrication system and other degrees of water, in such a case, can be divided into the following parts to analyze and deal with:

1. Electrical control part

After the electrical part of the vertical injection molding machine is flooded, it will cause all kinds of electrical components of the vertical injection molding machine to rust and corrosion and reduce the insulation performance. Generally follow the following steps:

1. Disconnect the power supply of all vertical injection molding machines;

2. Remove the battery on the main board of the I/O computer within the shortest time after water is poured into the vertical injection molding machine (customers are advised to operate in time), because the I/O board is not removed when the battery is not removed.

Individual components are still in the power state, which will accelerate the degree of rust and corrosion of these components, will increase the difficulty of component maintenance and maintenance costs;

3. Remove the electrical components in the whole point box of the vertical injection molding machine (operated by the service personnel) and clean them with alcohol. If necessary, clean the parts separately, including I/O board, 24V power supply and 5V power supply

Source, transformer, ac contactor, air switch, axial flow fan, etc.

4, dry, with field drying hopper will be fully dry, all components can be decomposed components stratification in drying hopper after clean, drying temperature in 50 ~ 70 ℃, the drying time

8~10 hours, test whether the insulation resistance value meets the requirements (200K), judge whether completely dry;

5. Electrify the completely dry electrical components separately (operated by the service personnel), and then install them into use after they are checked and intact.

Ii. Hydraulic part of vertical injection molding machine

1. The motor oil pump of the vertical injection molding machine cannot be started, because the moisture entering the hydraulic oil after starting the motor of the vertical injection molding machine may enter the hydraulic piping system of the vertical injection molding machine, resulting in gold

Corrosion of hydraulic components;

2, check whether the vertical injection molding machine hydraulic oil water. Open the plug at the bottom of the oil tank on the stand of the vertical injection molding machine and release a small amount of oil

The crackling sound in the combustion process indicates that there is water in the hydraulic oil and all hydraulic oil needs to be replaced. (anhydrous copper sulfate can also be used to test whether it turns blue, which indicates the presence of water);

3. If the oil contains water, the hydraulic oil in the oil tank of vertical injection molding machine shall be replaced. Wipe the oil tank with a clean cloth before changing the oil;

Iii. Other parts

1, vertical injection molding machine motor

Separate the stator and rotor of the motor, and dry the stator windings (it can be processed by professional repair motor, or it can be dried in the motor housing with 100W incandescent lamp for about 8 minutes)

Hours), must ensure that the insulation resistance acuity 0.4 M Ω, vertical injection molding machine motor bearing down to check whether use after rinsing with gasoline, are replaced with specifications bearing;

2, vertical injection molding machine lubrication pump

The vertical injection molding machine lubrication pump motor, stator and rotor pump bravery separation, can use dry drying hopper fixed set of winding processing, must ensure that the insulation resistance acuity 0.4 M Ω, bravery, such as pump

If the rust stuck with the mold rust remover can be sprayed into the inside of the pump gallbladder rust, pump gallbladder gear rotation can be flexible.

3, vertical injection molding machine type must be connector plug, connector socket (aviation plug) separate, dry treatment after cleaning (available hair dryer).

Servo motor and control system of vertical injection molding machine

1, vertical injection molding machine, electrical components, circuit boards, first using alcohol to clean with the wind blow dry reoccupy after oven or drying hopper to 55 ℃ dry for 24 hours.

2. The servo motor of vertical injection molding machine should pay attention to the drying of encoder and motor stator and the protection of motor bearing to avoid rusting.

After the above parts are processed, the parts shall be assembled again and electrified for test.
